Sternal fractures caused by blunt chest trauma are associated with an increased incidence of cardiac injury. Reports of the incidence of cardiac injury associated with sternal fracture range from 18% to 62%. Delayed cardiac tamponade is a rare phenomenon that appears days or weeks after injury. Moreover, after nonpenetrating chest trauma, cardiac tamponade is very rare and occurs in less than 1 of 1000. This case describes a patient who had delayed cardiac tamponade 17 days after a severe blunt chest trauma.

There have been several anthropological studies on trauma analysis in recent literature, but few studies have focused on the differences between the three mechanisms of trauma (sharp force trauma, blunt force trauma and ballistics trauma). The hypothesis of this study is that blunt force and ballistics fracture patterns in the skull can be differentiated using concentric fractures. Two-hundred and eleven injuries from skulls exhibiting concentric fractures were examined to determine if the mechanism of trauma could be determined by beveling direction. Fractures occurring in buttressed and non-buttressed regions were examined separately. Contingency tables and Pearson's Chi-Square were used to evaluate the relationship between the two variables (the mechanism of trauma and the direction of beveling), while Pearson's r correlation was used to determine the strength of the relationship. Contingency tables and Chi-square tests among the entire sample, the buttressed areas, and the non-buttressed areas led to the null hypothesis (no relationship) to be rejected. Pearson's r correlation indicated that the relationship between the variables studied is greater than chance allocation.

Blunt trauma to the temporal region can cause fracture of the skull base, loss of hearing, vestibular symptoms and otorrhoea. The most common causes of blunt trauma to the ear and surrounding area are motor vehicle accidents, violent encounters, and sports-related accidents. We present an obscure case of a man who was struck in the ear by a flying fish while wading in the sea with resulting temporal bone fracture, sudden deafness, vertigo, cerebrospinal fluid otorrhoea, and pneumocephalus.

AIM: The aim of this retrospective study was to report the scapular fractures in patients with blunt chest trauma and to present the type and the frequency of associated thoracic injuries. MATERIAL AND METHODS: Nine patients with fractures of the scapula were included in the study. The mechanisms of the injury, the type of scapular fractures and associated thoracic injuries were analysed. RESULTS: Scapular fractures were caused by high-energy blunt chest trauma. The body of the scapula was fractured in all scapular fractures. In all cases, scapular fractures were associated with other thoracic injuries (average 3.25/per case). Rib fractures were present in eight patients, fractured clavicula - in four cases, the affection of pleural cavity - in eight of the patients and pulmonary contusion in all nine cases. Eight patients were discharged from the hospital up to the 15th day. One patient had died on the 3rd day because of postconcussional lung oedema. CONCLUSIONS: The study confirms the role of scapular fractures as a marker for the severity of the chest trauma (based on the number of associated thoracic injuries), but doesn’t present scapular fractures as an indicator for high mortality in blunt chest trauma patients.

Trauma is the third most common cause of death in the West. In the US, approximately 90,000 deaths annually are traumatic in nature and over 75% of casualties from blunt trauma are due to chest injuries. Cardiac injuries from rib fractures following blunt trauma are extremely rare. We report the unusual case of a patient who fell from a height and presented with haemopericardium and haemothorax as a result of left ventricular and lingular lacerations and was sucessfully operated upon.

We report the successful conservative management of an unusual case of esophageal perforation associated with an upper thoracic spinal fracture from blunt trauma in Minamata, Kumamoto, Japan. A 69-year-old man became paraplegic secondary to an L1 burst fracture caused by a boating accident and underwent posterior fixation on the day of admission. The patient also had a minimally displaced T4 vertebral fracture. Fever, dyspnea and elevated inflammatory markers all persisted postoperatively. Computed tomography showed free mediastinal air at the T4 level, and an esophagram showed contrast medium leakage, which helped diagnose esophageal perforation. The esophageal perforation healed with conservative treatment without life-threatening complications. The possibility of esophageal injury should always be considered when treating upper thoracic spinal injuries due to blunt trauma. PMID:28053736

Pelvic hemorrhage has been implicated as the cause of death in 50% of patients who die following pelvic fractures. To establish correlates of morbidity and mortality from pelvic fractures due to blunt trauma, we reviewed 236 patients treated during 4 years. The average age of the 144 men and 92 women was 31.5 years, the average Injury Severity Score was 21.3, the average blood requirement was 5 units, and the average hospital stay was 16.8 days. One hundred fifty-two patients (64.4%) were injured in motor vehicle accidents, 33 (14%) had motor vehicle-pedestrian accidents, 16 (6.8%) had crush injuries, 12 (5.1%) each had either motorcycle accidents or falls, and 11 (4.6%) had miscellaneous accidents. Eighteen patients (7.6%) died, with seven (38.9%) deaths due to hemorrhage. Only one death was caused by pelvic hemorrhage. Other deaths were due to hemorrhage from other sites (6), head injury (5), sepsis or multiple-organ failure (4), pulmonary injury (1), and pulmonary embolus (1). None of the septic deaths was related to a pelvic hematoma. Multivariate multiple regression analysis showed that the severity of injury was correlated with indices of severity of pelvic fractures such as fracture site (p less than 0.0001), fracture displacement (p less than 0.005), pelvic stability (p less than 0.0001), and vector of injury (p less than 0.01). However death could not be predicted on the basis of these indices of severity (p greater than 0.28). Of the nine patients who underwent pelvic arteriography, three required embolization of actively bleeding pelvic vessels, but seven had intra-abdominal hemorrhage that required laparotomy, and eight developed a coagulopathy. Massive bleeding from pelvic fractures was uncommon, and the major threat of hemorrhage was from nonpelvic sites. Furthermore, although injury severity was correlated with the severity of the pelvic fracture, hospital outcome was determined by associated injuries and not by the pelvic fracture. PMID:2039283

There is very limited knowledge about how long perimortem fracture characteristics persist into the postmortem interval (PMI). Therefore, in this study, 60 porcine long bones were exposed to natural taphonomic conditions and fractured with a steel bone breaking apparatus every 28 days throughout a 141-day period. Differences between macroscopic blunt force trauma fracture characteristics (fracture angle, surface morphology, and outline) were examined to determine if they varied over time or in relationship to bone moisture content (ash weight) and overall assessment. There are significant relationships between (1) PMI and percent ash weight (%AW), fracture surface, and fracture angle and (2) %AW and fracture surface and fracture angle. Bone moisture content correlates significantly with fracture morphology and other characteristics commonly used by forensic anthropologists to determine the timing of traumatic injuries. However, fracture characteristics normally associated with perimortem trauma can persist long into the PMI.

Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

The lesions of the skull following perforating traumas can create complex fractures. The blunt traumas can, according to the swiftness and the shape of the object used, create a depressed fracture. The authors describe through two clinical cases the lesional characteristic of the blunt traumas, perforating the skull using a hammer. In both cases the cranial lesions were very typical: they were geometrical, square shaped, of the same size than the tool (head and tip of the hammer). On the outer table of the skull, the edges of the wounds were sharp and regular. On the inner table, the edges of the wounds were beveled and irregular. The bony penetration in the depressed fracture results from a rupture of the outer table of the bone under tension, in periphery, by the bend of the bone to the impact (outbending) and then, from the inner table with comminuted bony fragmentation. Breeding on the fractures of the size and the shape of the blunt objects used is inconstant and differs, that it is the objects of flat surface or wide in opposition to those of small surface area. Fractures morphologies depend on one hand on these extrinsic factors and on the other hand, of intrinsic factors (structure of the bone). To identify them, we had previously conducted experimental work on cranial bone samples. The bone was submitted to a device for three-point bending. This work had shown properties of thickness and stiffness of the various areas of the vault. Our cases are consistent with these results and illustrate the variability of bone lesions according to region and mode of use of blunt weapons. Many studies have identified criteria for identification of the weapons and the assistance of digital and biomechanical models will be an invaluable contribution with this aim in the future.

Laryngeal fracture is a rare traumatic injury, potentially fatal, with an estimated incidence of 1 in 30,000 patients admitted to severe trauma centers. Because of the rarity of this injury, physician may be not aware of its existence, leading to a late diagnosis of this entity. We report a case of a 59-year-old woman admitted to the emergency room after a motorcycle accident with cervical trauma. The patient presented with dysphonia, hemoptysis, cervical subcutaneous emphysema, and increasing respiratory distress that led to the intubation of the patient. CT-scan demonstrated displaced fracture of the cricoid and thyroid cartilage. The patient was submitted to tracheostomy and the fracture was surgically repaired. Tracheostomy was removed in third postoperative month. The patient presented a good recovery, reporting only hoarseness but without swallowing or breathing problems at 6-month follow-up.

Veterinary pathologists commonly encounter lesions of blunt trauma. The development of lesions is affected by the object's mass, velocity, size, shape, and angle of impact and by the plasticity and mobility of the impacted organ. Scrape, impact, and pattern abrasions cause localized epidermal loss and sometimes broken hairs and implanted foreign material. Contusions are best identified after reflecting the skin, and must be differentiated from coagulopathies and livor mortis. Lacerations-traumatic tissue tears-may have irregular margins, bridging by more resilient tissue, deviation of the wound tail, crushed hairs, and unilateral abrasion. Hanging or choking can cause circumferential cervical abrasions, contusions and rupture of hairs, hyoid bone fractures, and congestion of the head. Other special forms of blunt trauma include fractured nails, pressure sores, and dog bites. Ocular blunt trauma causes extraocular and intraocular hemorrhages, proptosis, or retinal detachment. The thoracic viscera are relatively protected from blunt trauma but may develop hemorrhages in intercostal muscles, rib fractures, pulmonary or cardiac contusions or lacerations with subsequent hemothorax, pneumothorax, or cardiac arrhythmia. The abdominal wall is resilient and moveable, yet the liver and spleen are susceptible to traumatic laceration or rupture. Whereas extravasation of blood can occur after death, evidence of vital injury includes leukocyte infiltration, erythrophagocytosis, hemosiderin, reparative lesions of fibroblast proliferation, myocyte regeneration in muscle, and callus formation in bone. Understanding these processes aids in the diagnosis of blunt force trauma including estimation of the age of resulting injuries.

Simple radiography is the best diagnostic tool for rib fractures caused by chest trauma, but it has some limitations. Thus, other tools are also being used. The aims of this study were to investigate the effectiveness of ultrasonography (US) for identifying rib fractures and to identify influencing factors of its effectiveness. Between October 2003 and August 2007, 201 patients with blunt chest trauma were available to undergo chest radiographic and US examinations for diagnosis of rib fractures. The two modalities were compared in terms of effectiveness based on simple radiographic readings and US examination results. We also investigated the factors that influenced the effectiveness of US examination. Rib fractures were detected on radiography in 69 patients (34.3%) but not in 132 patients. Rib fractures were diagnosed by using US examination in 160 patients (84.6%). Of the 132 patients who showed no rib fractures on radiography, 92 showed rib fractures on US. Among the 69 patients of rib fracture detected on radiography, 33 had additional rib fractures detected on US. Of the patients, 76 (37.8%) had identical radiographic and US results, and 125 (62.2%) had fractures detected on US that were previously undetected on radiography or additional fractures detected on US. Age, duration until US examination, and fracture location were not significant influencing factors. However, in the group without detected fractures on radiography, US showed a more significant effectiveness than in the group with detected fractures on radiography (P=0.003). US examination could detect unnoticed rib fractures on simple radiography. US examination is especially more effective in the group without detected fractures on radiography. More attention should be paid to patients with chest trauma who have no detected fractures on radiography. PMID:28119889

The present photocase illustrates the possible mechanism of direct cardiac injuries from broken sharp jagged fractured ends of ribs in blunt force trauma to the chest in run over traffic mishaps. We propose that the projecting fractured ends of the ribs penetrate the underlying thoracic organs due to the transient phenomenon of deformation of chest cavity under pressure in run over traffic mishaps.

In this paper we present a unique pattern of blunt force cranial trauma that was observed in 10 of a sample of 85 crania from a Cambodian skeletal collection comprised of Khmer Rouge victims. Initial examination of the trauma, which presents as substantial damage to the occipital with fractures extending to the cranial base, suggested the pattern was classifiable as a basilar or ring fracture. However, further investigation, including trauma analysis and historical research, revealed that this fracture type is distinctive from basilar and ring fractures. Historical data indicate that a particular execution method was the likely source of the trauma. Recognition of this trauma pattern is significant because it exemplifies the distinct fracture configuration resulting from an apparently categorical and methodical execution technique. Identification of this fracture type could potentially assist forensic investigators in the recognition of specific methods of murder or execution.

Deaths due to blunt force trauma to the head as a result of assault are some of the most common cases encountered by the practicing forensic pathologist. Previous studies have shown inflicting injury to the head region is one of the most effective methods of murder. The important factors that determine severity of trauma include the type of weapon used, type and site of skull fracture, intracranial haemorrhage and severity of brain injury. The aim of this study was to determine the characteristics of blunt force trauma to the skull produced by different instruments. Nine adult monkeys (Macaca fascicularis) skulls were used as models. Commonly found blunt objects comprising of Warrington hammer, hockey stick and open face helmet were used in this study. A machine calibrated force generator was used to hold the blunt object in place and to hit the skulls at forces of 12.5N and 25N. Resultant traumatic effects and fractures (linear, depressed, basilar, comminuted, and distastic) were analyzed according to type of blunt object used; surface area of contact and absolute force (N/cm(2)) delivered. Results showed that all investigated instruments were capable of producing similar injuries. The severity of trauma was not related to the surface area of contact with the blunt objects. However, only high absolute forces produced comminuted fractures. These findings were observational, as the samples were too small for statistical conclusions.

Duodenal perforation after a blunt abdominal trauma is a rare emergency situation that can result in life-threatening complications. We report on a woman who had a perforation of the duodenum after a supposed mild blunt abdominal trauma. Unremarkable at the initial presentation, the patient presented with acute abdominal pain and a retroperitoneal abscess five days after the initial trauma. The duodenal repair was performed with a Roux-Y anastomosis. Difficulties in diagnosis are very common, but the early recognition of the rupture is essential. The contrast-enhanced CT scan is the gold standard for diagnosis. Surgical management depends on the severity of the trauma and must be chosen on an individual basis.

Blunt laryngotracheal trauma can be a life-threatening event. Two cases of isolated blunt laryngotracheal trauma in pediatric patients are presented. One case involves a 12-year-old mate who suffered isolated tracheal trauma from a fall. He developed respiratory distress and required a tracheostomy. Intraoperatively he was noted to have a thyroid cartilage fracture. The other case involves a 14-year-old female who was kicked in the neck by a horse. After unsuccessful intubation attempts that completed a tracheal transection, she required an emergency cricothyrotomy and a subsequent tracheostomy. The diagnosis, differential diagnosis, associated injuries, and treatment options for blunt laryngeal trauma are reviewed.

Background. Blunt chest wall trauma accounts for over 10% of all trauma patients presenting to emergency departments worldwide. When the injury is not as severe, deciding which blunt chest wall trauma patients require a higher level of clinical input can be difficult. We hypothesized that patient factors, injury patterns, analgesia, postural condition, and positive airway pressure influence outcomes. Methods. The study population consisted of patients hospitalized with at least 3 rib fractures (RF) and at least one pulmonary contusion and/or at least one pneumothorax lower than 2 cm. Results. A total of 140 patients were retrospectively analyzed. Ten patients (7.1%) were admitted to intensive care unit (ICU) within the first 72 hours, because of deterioration of the clinical conditions and gas exchange with worsening of chest X-ray/thoracic ultrasound/chest computed tomography. On univariable analysis and multivariable analysis, obliged orthopnea (p = 0.0018) and the severity of trauma score (p < 0.0002) were associated with admission to ICU. Conclusions. Obliged orthopnea was an independent predictor of ICU admission among patients incurring non-life-threatening blunt chest wall trauma. The main therapeutic approach associated with improved outcome is the prevention of pulmonary infections due to reduced tidal volume, namely, upright postural condition and positive airway pressure.

Survival following tracheoesophageal transection is uncommon. Establishing a secure airway has the highest priority in trauma management. Understanding the mechanism of the incident can be a useful adjunct in predicting the likelihood and severity of specific anatomical patterns of injuries. We discuss published literature on combined tracheoesophageal injuries after blunt neck trauma and their outcome. A search of MEDLINE for papers published regarding tracheoesophageal injury was made. The literature search identified 14 such articles referring to a total of 27 patients. Age ranged from 3-73 years. The mechanism of injury was secondary to a rope/wire in 33%, metal bar in 4% of cases and unspecified in 63%. All of the patients were managed surgically. A number of tissues were used to protect the anastomosis including pleural and sternocleidomastoid muscle flaps. There were no reported mortalities. Patients with combined tracheoesophageal injury after blunt neck trauma require acute management of airway along with concomitant occult injuries.

There have been several forensic pathological studies on the distinction between falls from height and homicidal blows in blunt head trauma, but few studies have focused on suicidal blows. Self-inflicted blunt head trauma is usually a part of a complex suicide with more than one suicidal method applied. Actually, no reports on suicide indicate blunt head trauma to be the singular cause of death in recent publications. Cases with self-inflicted blunt trauma are often challenging for those involved in the investigation because they are confronted with findings that are also found in homicides. A refined guideline to differentiate suicidal blows from homicidal blows in blunt head trauma allows for a more accurate representation of the events surrounding death. This paper presents two cases of suicide by self-inflicted blunt head trauma in which blunt head trauma from repeatedly hitting the decedent's head with a hammer was considered to be the only cause of death.

Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography (CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging (MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful non-operative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma. PMID:26981225

"War games" are gaining popularity in the western United States. These recreational contests involve members of one team attempting to shoot their opponents with high-velocity dye or paint pellets fired from air guns. Unfortunately, serious eye injuries occur when participants do not use protective eye wear. We report a case of severe blunt ocular trauma resulting in a hyphema, choroidal rupture, and retinal and vitreal hemorrhage secondary to a paint pellet striking an unprotected eye. This injury resulted in a significant visual defect in this patient.

Occipital condyle fractures (OCFs) have been treated as rare traumatic injuries, but the number of reported OCFs has gradually increased because of the popularization of computed tomography (CT) and magnetic resonance imaging (MRI). The patient in this report presented with OCFs and C1 dislocation, along with traumatic cerebellar hemorrhage, which led to craniovertebral junction instability. This case was also an extremely rare clinical condition in which the patient presented with traumatic lower cranial nerve palsy secondary to OCFs. When the patient was transferred to our hospital, the occipital bone remained defective extensively due to surgical treatment of cerebellar hemorrhage. For this reason, concurrent cranioplasty was performed with resin in order to fix the occipital bone plate strongly. The resin-made occipital bone was used to secure a titanium plate and screws enabled us to perform posterior fusion of the craniovertebral junction. Although the patient wore a halo vest for 3 months after surgery, lower cranial nerve symptoms, including not only neck pain but also paralysis of the throat and larynx, improved postoperatively. No complications were detected during outpatient follow-up, which continued for 5 years postoperatively. PMID:27800203

Hollow viscus injuries of the digestive tract are an uncommon occurrence in blunt abdominal trauma. We report a 39-year-old male who was hit by a vehicle as a pedestrian and admitted to the Sultan Qaboos University Hospital, Muscat, Oman, in 2015. He underwent an exploratory laparotomy which revealed injuries to the distal stomach, liver and descending colon. Postoperatively, the patient was febrile, tachycardic and hypotensive. Abdominal examination revealed distention and tenderness. The next day, a repeat laparotomy identified a gastric injury which had not been diagnosed during the initial laparotomy. Although the defect was repaired, the patient subsequently died as a result of multiorgan failure. Missed gastric injuries are rare and are associated with a grave prognosis, particularly for trauma patients. Delays in diagnosis, in addition to associated injuries, contribute to a high mortality rate. PMID:28003902

Chest trauma has a significant relevance on outcome after severe trauma. Clinically, impaired lung function typically occurs within 72 hours after trauma. However, the underlying pathophysiological mechanisms are still not fully elucidated. Therefore, we aimed to establish an experimental long-term model to investigate physiological, morphologic and inflammatory changes, after severe trauma. Male pigs (sus scrofa) sustained severe trauma (including unilateral chest trauma, femur fracture, liver laceration and hemorrhagic shock). Additionally, non-injured animals served as sham controls. Chest trauma resulted in severe lung damage on both CT and histological analyses. Furthermore, severe inflammation with a systemic increase of IL-6 (p = 0.0305) and a local increase of IL-8 in BAL (p = 0.0009) was observed. The pO2/FiO2 ratio in trauma animals decreased over the observation period (p < 0.0001) but not in the sham group (p = 0.2967). Electrical Impedance Tomography (EIT) revealed differences between the traumatized and healthy lung (p < 0.0001). In conclusion, a clinically relevant, long-term model of blunt chest trauma with concomitant injuries has been developed. This reproducible model allows to examine local and systemic consequences of trauma and is valid for investigation of potential diagnostic or therapeutic options. In this context, EIT might represent a radiation-free method for bedside diagnostics. PMID:28000769

Renal failure developed in 20 patients following blunt civilian trauma. Ten recovered normal renal function; 8 currently survive. Survivors and nonsurvivors did not differ in age, time from trauma to anuria, mean blood urea nitrogen or creatinine level prior to the first or to subsequent dialyses. However, there was an increased incidence of sepsis and liver failure in those who died. When outcome was related to site of injury, patients with closed head injury and/or intra-abdominal injury had a worse prognosis than those with thoracic or extremity injury only. Only 2 patients with perforated bowel survived; both had peritoneal dialysis combined with peritoneal lavage with antibiotic solutions. Mortality in patients with posttraumatic renal failure remains high; however, death is usually a result of associated complications rather than a result of the renal failure. Aggressive management of other complications of the trauma, especially sepsis or potential sepsis, is necessary. We recommend peritoneal dialysis combined with peritoneal antibiotic lavage where there is a potential for posttraumatic intra-abdominal sepsis associated with renal failure. PMID:843128

We report 2 cases of delayed hemothorax due to blunt chest trauma. A 48-year-old man who fell down and got a blow at the right chest had a checkup with a 1st aid outpatient. By the X-rays at the time of the 1st examination, the hemothorax was not noted. The next day, He has been transported to our hospital for atypical absence. Hemothorax was suggested by computed tomography (CT) and chest drainage was enforced. A 79-year-old man got a blow at the anterior chest by traffic accident and had a checkup in the 1st hospital. The abnormality was not recognized in the chest CT at that time. For the left hemiparesis, he was transported to our hospital the next day. Hemothorax was suggested by CT and chest drainage was enforced.

Blunt abdominal traumas are uncommonly encountered despite their high prevalence, and injuries to the organ like duodenum are relatively uncommon (occurring in only 3%-5% of abdominal injuries) because of its retroperitoneal location. Duodenal injury combined with gastric perforation from a single abdominal trauma impact is rarely heard. The aim of this case report is to present a rare case of blunt abdominal trauma with combined gastric and duodenal injuries. PMID:25738037

Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended.

Right atrial rupture secondary to blunt trauma is exceedingly rare. We present a case report of blunt chest trauma and right atrial rupture in a patient with a background of pericardiectomy that were successfully managed surgically. Right atrial rupture must be considered as a differential diagnosis in patients with blunt chest trauma. In patients with previous pericardiectomy, this injury may manifest with massive hemothorax, and insertion of a chest drain should be performed with extreme caution. In our experience, urgent exploratory thoracotomy and repair of the defect are the mainstays of acute management.

A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

Pediatric laryngotracheal injuries from blunt neck trauma are extremely rare, but can be potentially catastrophic. Early diagnosis and skillful airway management is critical in avoiding significant morbidity and mortality associated with these cases. We present a case of a patient who suffered a complete tracheal transection and cervical spine fracture following a clothesline injury to the anterior neck. A review of the mechanisms of injury, clinical presentation, initial airway management, and anesthetic considerations in laryngotracheal injuries from blunt neck trauma in children are presented.

We present our experience with computed tomographic (CT) cystography for the diagnosis of bladder rupture in patients with blunt abdominal and pelvic trauma and compare the results of CT cystography to operative exploration. We identified all blunt trauma patients diagnosed with bladder rupture from January 1992 to September 1998. We also reviewed the radiology computerized information system (RIS) for all CT cystograms performed for the evaluation of blunt trauma during the same time period. The medical records and pertinent radiographs of the patients with bladder rupture who underwent CT cystography as part of their admission evaluation were reviewed. Operative findings were compared to radiographic findings. Altogether, 316 patients had CT cystograms as part of an initial evaluation for blunt trauma. Of these patients, 44 had an ultimate diagnosis of bladder rupture; 42 patients had CT cystograms indicating bladder rupture. A total of 28 patients underwent formal bladder exploration; 23 (82%) had operative findings that exactly (i.e., presence and type of rupture) matched the CT cystogram interpretation. The overall sensitivity and specificity of CT cystography for detection of bladder rupture were 95% and 100%, respectively. For intraperitoneal rupture, the sensitivity and specificity were 78% and 99%, respectively. CT cystography provides an expedient evaluation for bladder rupture caused by blunt trauma and has an accuracy comparable to that reported for plain film cystography. We recommend CT cystography over plain film cystography for patients undergoing CT evaluation for other blunt trauma-related injuries.

Vessel-whale collision events represented the ultimate cause of death for 21 (52.5%) of the 40 North Atlantic right whales (Eubalaena glacialis) necropsied between 1970 and December 2006. Injuries seen in vessel-struck whales fall into two distinct categories: 1) sharp trauma, often resulting from contact with the propeller, and 2) blunt trauma, presumably resulting from contact with a vessel's hull. This study analyzes four trauma cases that resulted from vessel-whale collisions, which together provide a framework for a more critical understanding of lethal blunt and sharp trauma resulting from vessel collisions with right whales. In case no. 1, contact with a propeller resulted in three deep lacerations. The animal survived acute trauma only to succumb nearly 14 years later when the lesions reopened and became infected. In case no. 2, anecdotal reports linked the laceration of large arteries of the peduncle and histologic evidence of perimortem trauma at a bone fracture site to vessel-whale collision trauma. Case no. 3 had a laceration of the oral rete and a fracture of the rostrum. Both of the areas displayed histologic evidence of perimortem blunt trauma. Finally, in case no. 4, an antemortem mandibular fracture, two additional skull fractures, and widespread hemorrhage were consistent with severe blunt trauma. Evidence from each case, including the timing of trauma relative to the time of death and identifying characteristics of both trauma types, are presented. Before this study, no detailed comparative analysis of trauma pathology that resulted from lethal interactions between vessels and right whales had been conducted. This study demonstrates the importance of detailed gross and histologic examination in determining the significance and timing of traumatic events. This work represents a new paradigm for the differential diagnosis of lethal sharp and blunt trauma in right whales hit by ships and will enhance the present understanding of the impact of

The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

Objective Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. Materials and Methods We investigated the incidence of bowel transection in 513 patients admitted for blunt abdominal trauma who underwent multidetector CT (MDCT). The MDCT findings of 8 patients with a surgically proven complete bowel transection were assessed retrospectively. We report novel CT signs that are unique for transection, such as complete cutoff sign (transection of bowel loop), Janus sign (abnormal dual bowel wall enhancement, both increased and decreased), and fecal spillage. Results The incidence of bowel transection in blunt abdominal trauma was 1.56%. In eight cases of bowel transection, percentage of CT signs unique for bowel transection were as follows: complete cutoff in 8 (100%), Janus sign in 6 (100%, excluding duodenal injury), and fecal spillage in 2 (25%). The combination of complete cutoff and Janus sign were highly specific findings in patients with bowel transection. Conclusion Complete cut off and Janus sign are the unique CT findings to help detect bowel transection in blunt abdominal trauma and recognition of these findings enables an accurate and prompt diagnosis for emergency laparotomy leading to reduced mortality and morbidity.

To determine the effect of admission body weight on blunt trauma victims, a chart review of all patients greater than 12 years of age admitted to Sentara Norfolk General Hospital between January 1 and July 31, 1987 was undertaken. The charts of 351 patients were reviewed; 184 records contained admission height and weight. These 184 patients made up the study group and age, gender, injuries, Injury Severity Score (ISS), ventilator days (VD), complications, length of stay (LOS), and outcome were noted. Body Mass Index (BMI) (weight (kg)/(height(m))2, was calculated for each patient. The average ISS was 21.87 (range, 1-66) and the average BMI was 25.15 kg/m2 (range, 16-46 kg/m2). The overall mortality for the population was 9%. The population was grouped according to BMI: average (less than 27 kg/m2), overweight (27-31 kg/m2), and severely overweight (greater than 31 kg/m2). The mortality of 5.0% and 8.0% in the average and overweight groups was not different. The severely overweight group had a higher mortality at 42.1% compared with the other two groups (p less than 0.0001). The groups did not differ in age, ISS, LOS, nor VD. Age, BMI, and ISS were subjected to regression analysis. By this method BMI and ISS were independent determinants of outcome (p less than 0.0001). There was an increase in complications, mainly pulmonary problems, in the SO group (p less than 0.05). The three groups were subdivided into survivors and nonsurvivors. The nonsurvivors had a longer average LOS at 26.6 days compared with nonsurvivors in the overweight (5.0 days) or severely overweight (8.62 days) groups (p less than 0.007). The severely group was characterized by a rapid deterioration and demise that was unresponsive to intervention. ISS did not differ among nonsuvivors. Among survivors the severely overweight group had a lower ISS, 9.73. This was different from the overweight group (21.57) and from the average group (20.21) (p less than 0.04).

The diagnosis of blunt injury to the gallbladder may constitute a significant challenge to the diagnostician. There is often a delay in presentation with non-specific clinical symptoms. In the absence of reliable clinical symptoms, diagnostic imaging becomes an invaluable tool in the rapid identification of gallbladder injury. We present a case of isolated gallbladder injury following blunt abdominal trauma which was diagnosed by computed tomography and subsequently confirmed by cholecystectomy.

Imaging plays an essential part of chest trauma care. By definition, the employed imaging technique in the emergency setting should reach the correct diagnosis as fast as possible. In severe chest blunt trauma, multidetector computer tomography (MDCT) has become part of the initial workup, mainly due to its high sensitivity and diagnostic accuracy of the technique for the detection and characterization of thoracic injuries and also due to its wide availability in tertiary care centers. The aim of this paper is to review and illustrate a spectrum of characteristic MDCT findings of blunt traumatic injuries of the chest including the lungs, mediastinum, pleural space, and chest wall.

The incidence of pancreatic injury following blunt abdominal trauma is rare. A timely accurate diagnosis of such injury is difficult and also the management remains controversial. Here, we reported the successful use of laparoscopy to diagnose, characterize and treat blunt pancreatic trauma in a 28-year-old male patient involved in a motor vehicle crash. An abdominal computed tomography scan showed peripancreatic fat stranding suggestive of pancreatic injury. With persistent clinical signs of peritonitis and laboratory investigations suggestive of pancreatitis, the patient underwent laparoscopic drainage of the lesser sac. The patient had an uneventful postoperative course. The management of patients with blunt pancreatic injuries should be tailored to individual situations. Our experience suggests that a timely laparoscopic management of traumatic pancreatic injury is safe approach in selected cases.

Diagnostic procedures such as peritoneal lavage, computed tomography, emergency angiography, nuclear scintigraphy, and contrast studies of the gastrointestinal and urinary tracts can assist in the identification, quantification, and localization of injury after blunt abdominal trauma. Use of these procedures should be determined by careful clinically assessment as part of an aggressive approach to the diagnosis of the injured patient. 22 references.

Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.

Background: In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. Objectives: To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. Patients and Methods: We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Results: Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Conclusions: Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid.

Background Although relatively rare, blunt injury to thoracic great vessels is the second most common cause of trauma related death after head injury. Over the last twenty years, the paradigm for management of these devastating injuries has changed drastically. The goal of this review is to update the reader on current concepts of diagnosis and management of blunt thoracic vascular trauma. Methods A review of the medical literature was performed to obtain articles pertaining to both blunt injuries of the thoracic aorta and of the non-aortic great vessels in the chest. Articles were chosen based on authors' preference and clinical expertise. Discussion Blunt thoracic vascular injury remains highly lethal, with most victims dying prior to reaching a hospital. Those arriving in extremis require immediate intervention, which may include treatment of other associated life threatening injuries. More stable injuries can often be medically temporized in order to optimize definitive management. Endovascular techniques are being employed with increasing frequency and can often significantly simplify management in otherwise very complex patient scenarios. PMID:19751511

While the neurobiology of post-traumatic stress disorder has been extensively researched, much less attention has been paid to the neural mechanisms underlying more covert but pervasive types of trauma (e.g., those involving disrupted relationships and insecure attachment). Here, we report on a neurobiological study documenting that mothers’ attachment-related trauma, when unresolved, undermines her optimal brain response to her infant’s distress. We examined the amygdala blood oxygenation level-dependent response in 42 first-time mothers as they underwent functional magnetic resonance imaging scanning, viewing happy and sad face images of their own infant, along with those of a matched unknown infant. Whereas mothers with no trauma demonstrated greater amygdala responses to the sad faces of their own infant as compared to their happy faces, mothers who were classified as having unresolved trauma in the Adult Attachment Interview (Dynamic Maturational Model) displayed blunted amygdala responses when cued by their own infants’ sadness as compared to happiness. Unknown infant faces did not elicit differential amygdala responses between the mother groups. The blunting of the amygdala response in traumatized mothers is discussed as a neural indication of mothers’ possible disengagement from infant distress, which may be part of a process linking maternal unresolved trauma and disrupted maternal caregiving.

Traumatic rupture of intracardiac structures is an uncommon phenomenon although there are a number of reports with regards to rupture of the tricuspid, mitral and aortic valves. We report the case of a 25-year-old patient who presented with acute aortic and mitral valve regurgitation of traumatic origin. Both lesions were seen separated by 2 weeks. Pathophysiology is reviewed. The combination of both aortic and mitral lesions following blunt chest trauma is almost exceptional.

Objective The objective of this study was to determine if the white blood cell count can predict severity of injury in blunt trauma victims. Methods This was a retrospective study comparing two groups of blunt trauma victims by severity of injury, one with significant injury and one without significant injury, and comparing their initial WBC in the emergency department (ED). We also examined if WBC correlates with degree of injury using Injury Severity Score (ISS) in both groups combined. Further, we examined the WBC as a predictor of serious injury. Results Our study showed a difference in mean WBC between the two groups that was statistically significant (p<0.001). A positive relationship between ISS and WBC was found, although the association was weak (correlation coefficient = 0.369). While the WBC had moderate discriminatory capability for serious injury, it could not, in isolation, reliably rule in or out serious injury. Nevertheless, this study supports using WBC on presentation to the ED as an adjunct for making disposition decisions. Conclusion A significant elevation in WBC in a blunt trauma patient, even with minimal initial signs of severe injury, should heighten suspicion for occult injury. PMID:19561712

ABSTRACT Gallbladder rupture following blunt abdominal trauma is a rare event recognized on evaluation and treatment of other visceral injuries during laparotomy. Isolated gallbladder rupture secondary to blunt abdominal trauma is even more uncommon. The clinical presentation of gallbladder injury is variable, resulting in a delay in diagnosis and treatment. We report the case of a patient who suffered an isolated gallbladder rupture due to blunt abdominal trauma. PMID:23843066

Background Traumatic perforation of the distal oesophagus due to blunt trauma is a very rare condition and is still associated with a significant morbidity and mortality. This is further exacerbated by delayed diagnosis and management as symptoms and signs are often masked by or ascribed to more common blunt thoracic injuries. Case report We present a case of a distal oesophageal perforation, secondary to a fall from a third storey window, which was masked by concomitant thoracic injuries and missed on both computed tomography imaging and laparotomy. The delay in his diagnosis significantly worsened the patient's recovery by allowing the development of an overwhelming chest sepsis that contributed to his death. Conclusion Early identification of an intrathoracic oesophageal perforation requires deliberate consideration and is essential to ensure a favorable outcome. Treatment should be individualised taking into account the nature of the oesophageal defect, time elapsed from injury and the patient's general condition. PMID:17374175

During the 5-year period from January 1978 through December 1982, 196 patients with blunt trauma to the small bowel, colon, or mesentery were treated at the Maryland Institute for Emergency Medical Services Systems (MIEMSS) Shock Trauma Center. More than 80% of these patients were the victims of motor vehicle accidents and therefore commonly had multisystem injuries. Sixty of these patients suffered 83 major injuries in the form of perforation or mesenteric injury resulting in ischemic bowel. This group accounted for 6.9% of the 870 patients who had celiotomy for blunt trauma during this period. Several significant observations were made. All injuries, except one, were diagnosed by peritoneal lavage. Only two duodenal injuries were present. Perforations involving the jejunum and ileum were distributed throughout the entire length of the small bowel. Colon injuries comprised one-fourth of the major injuries, with most occurring in the ascending and sigmoid colon. There were 16 deaths, 6 of which occurred as a result of complications from the bowel injury. PMID:3970600
Behind Armour Blunt Trauma (BABT) is the non-penetrating injury resulting from the rapid deformation of armours covering the body. The deformation of the surface of an armour in contact with the body wall arises from the impact of a bullet or other projectile on its front face. The deformation is part of the retardation and energy absorbing process that captures the projectile. In extreme circumstances, the BABT may result in death, even though the projectile has not perforated the armour. An escalation of the available energy of bullets and the desire of armour designers to minimise the weight and bulk of personal armour systems will increase the risk of BABT in military and security forces personnel. In order to develop materials that can be interposed between the armour and the body wall to attenuate the transfer of energy into the body, it is essential that the mechanism of BABT is known. There is a great deal of activity within UK and NATO to unravel the interactions; the mechanism is likely to be a combination of stress (pressure) waves generated by the rapid initial motion of the rear of the armour, and shear deformation to viscera produced by gross deflection of the body wall. Physical and computer model systems are under development to characterise the biophysical processes and provide performance targets for materials to be placed between armours and the body wall in order to attenuate the injuries (trauma attenuating backings-TABs). The patho-physiological consequences of BABT are being clarified by research, but the injuries will have some of the features of blunt chest trauma observed in road traffic accidents and other forms of civilian blunt impact injury. The injuries also have characteristics of primary blast injury. An overview diagnosis and treatment is described.

Duodenal rupture secondary to blunt trauma is a relatively uncommon event and is usually a result of a road traffic accident. As the duodenum is a retroperitoneal organ, delays in diagnosis can occur, as the patient may present with vague abdominal symptoms and other non-specific signs. Computed tomographic scanning is therefore a useful tool in the diagnosis of this condition. We present a 19-year-old girl who was hit in the abdomen with a football and subsequently had a duodenal rupture.

Esophageal injury following blunt trauma to chest is an extremely rare event, with only a limited number of cases being reported in the world literature. We report a case of perforation of the lower thoracic esophagus following a crush injury to the chest in a 14 year old child. An appropriately placed chest drain and decompression gastrostomy resulted in complete resolution of the esophageal leak within four weeks. This case report demonstrates that a conservative approach to lower thoracic esophageal perforations can be carried out successfully without the added morbidity of thoracotomy and risks of direct repair.

Blunt liver trauma is the most dangerous and the second most frequent solid organ trauma that occurs in the abdominal cavity. Management of this life-threatening situation remains a significant challenge. The present study identified that the patterns of blunt liver trauma were closely correlated with the characteristics of the blunt force. Illustrations of findings from this study have been included in the hope that they may aid surgeons in improving the management of this emergency. In total, 53 cases of blunt liver trauma that underwent laparotomy in the First Affiliated Hospital of Wenzhou Medical College between 1999 and 2009 were retrospectively studied. The cause of the injury, the direction and site of the blunt force, surgical records and CT films were carefully studied to obtain information on the patterns and severity of the liver injury and the correlation with blunt forces. Trauma in the right lobe of the liver was mainly caused by acceleration, deceleration and compression of the liver, while in the left lobe of the liver, acceleration was the main cause of the trauma. Liver lacerations were always located close to the attachment sites of the ligaments which bore the majority of the shearing stress. The characteristics of the blunt force play a key role in the different patterns of blunt liver trauma. A thorough understanding of the mechanisms of blunt liver trauma may aid doctors in the management of patients with this condition.

Purpose To evaluate outer retinal structural abnormalities in patients with visual deficits following closed globe blunt ocular trauma (cgBOT). Methods Nine subjects with visual complaints following cgBOT were examined between 1 month post-trauma and 6 years post-trauma. Spectral domain optical coherence tomography (SD-OCT) was used to assess outer retinal architecture, while adaptive optics scanning light ophthalmoscopy (AOSLO) was used to analyze photoreceptor mosaic integrity. Results Visual deficits ranged from central scotomas to decreased visual acuity. SD-OCT defects included focal foveal photoreceptor lesions, variable attenuation of the interdigitation zone, and mottling of the outer segment band, with one subject having normal outer retinal structure. AOSLO revealed disruption of the photoreceptor mosaic in all subjects, variably manifesting as foveal focal discontinuities, perifoveal hyporeflective cones, and paracentral regions of selective cone loss. Conclusions We observe persistent outer retinal disruption in subjects with visual complaints following cgBOT, albeit to a variable degree. AOSLO imaging allows assessment of photoreceptor structure at a level of detail not resolvable using SD-OCT or other current clinical imaging tools. Multimodal imaging appears useful for revealing the cause of visual complaints in patients following cgBOT. Future studies are needed to better understand how photoreceptor structure changes longitudinally in response to various trauma. PMID:24752010

Objective Multiple rib fractures (RFs) and pulmonary contusions (PCs), with resulting systemic lung inflammation, are the most common injuries caused by blunt chest trauma (BCT) in motor vehicle accidents. This study examined levels of the inflammation marker interleukin (IL)-6 and those of the acute-phase reactant surfactant protein (SP)-D in patients with BCT. Design Prospective, cross-sectional, observational study. Setting Single-centre, tertiary care hospital in the Black Sea Region of Turkey. Participants The study included 60 patients with BCT who were hospitalised in our thoracic surgery department. Parameters measures The SP-D and IL-6 serum levels of patients with RFs (two or more RFs) (n=30) and patients with PCs (n=30) were measured after 6 hours, 24 hours and 7 days, and compared with those of age-matched and gender-matched healthy participants. Results The 6-hour serum SP-D levels of the RFs (p=0.017) and PCs (p<0.001) groups were significantly higher than those of the healthy controls. The 24-hour and 7-day SP-D levels of both groups were also higher than the control group. The serum IL-6 levels of both groups were significantly higher than those of the control group. We have found Injury Severity Score to be independently related to 6-hour IL-6 (β=1.414, p<0.001) and 24-hour IL-6 levels (β=1.067, p<0.001). The development of complications was independently related to 6-hour SP-D level (β=0.211, p=0.047). Conclusions RFs and PCs after BCT lead to local and systemic inflammation due to lung injury. The levels of the systemic inflammation marker IL-6 and those of the acute-phase reactant SP-D were elevated in the present study. The SP-D level may be used as a marker in the follow-up of BCT-related complications. PMID:27733410

Although potato cannons are an area of great interest among internet users, they are almost completely unknown in the medical community. These simple ballistic devices are made from plastic plumbing pipes and are powered with propellant gas from aerosol cans. By combustion of the gas-oxygen mixture, a high pressure is produced which propels the potato chunks through the barrel. It is the aim of this study to investigate the hazardous potential of these shooting devices. Test shots were performed using three illegally manufactured potato cannons that were confiscated by police authorities. Velocity, impulse, kinetic energy, and energy density were calculated. The risk of head and chest injuries was investigated by using Sturdivan's Blunt Criterion (BC), an energy based five parametric trauma model assessing the vulnerability to blunt weapons, projectile impacts, and behind-body-armor exposures. The probability of lethality due to blunt impact trauma to the chest was assessed using Sturdivan's lethality model. For potential head impacts, all test shots far exceeded the critical BC (head) value which corresponds to a 50% risk of skull fracture. The risk of injury with regard to chest impacts was similar. All but two test shots far exceeded the critical BC (chest) value corresponding to a 50% risk of sustaining a thoracic skeletal injury of Abbreviated Injury Scale 2 or 3. The probability of a lethal injury due to blunt chest impact was as high as 20%. To conclude, this work demonstrates that potato cannons should be considered dangerous weapons rather than as toys used by adventurous adolescents.

The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (p<0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.

Reformatted CTs of the thoracic and lumbar spine (CT T/L) from CTs of the chest, abdomen, and pelvis (CT body) may be performed for screening the thoracolumbar spine in patients sustaining blunt trauma. The purpose of this study was to determine whether there was a difference in the rate of detection of spinal fractures on CTs of the body compared to the reformatted T/L spine. A secondary endpoint was to evaluate whether cases dictated by trainees improved fracture detection rate. We reviewed the records of 250 consecutive blunt trauma patients that received CTs of the chest, abdomen, and pelvis (CT body) with concurrent CT T/L reformats. Each report was reviewed to determine if there was a thoracolumbar fracture and whether a trainee had been involved in interpreting the CT body. If a fracture was identified on either report, then the number, type, and location of each fracture was documented. Sixty-nine fractures, from a total of 38 patients, were identified on either the CT of the body or the CT T/L. Sensitivity for CT body interpretations was 94 % (95 % CI: 86-98 %) compared to a 97 % (95 % CI: 89-100 %) sensitivity for the CT T/L (p > 0.5). Although the sensitivity was 97 % (95 % CI: 88-100 %) when a trainee was involved in interpreting the body CT, there was no statistically significant improvement. The results suggest that with careful scrutiny most spine fractures can be diagnosed on body CT images without the addition of spine reformats. The most commonly missed finding is an isolated non-displaced transverse process fracture, which does not require surgical intervention and does not alter clinical management. The results suggest that thin section reformats do not need to be routinely ordered in screening blunt trauma patients, unless a bony abnormality is identified on the thicker section body CT images.

Rupture of the membranous septum is a very rare complication of blunt chest trauma. In this report, we describe a 22-year-old man who sustained multiple blunt trauma injuries during a motor vehicle accident. Rupture of the membranous septum was diagnosed 48 hours after the initial trauma and the defect was closed with Gore-Tex (W.L. Gore & Assoc, Flagstaff, AZ). However, the operation was complicated by complete atrioventricular block requiring implantation of a permanent DDD pacemaker.

Purpose. To evaluate the oxygen saturation in retinal blood vessels in patients after closed-globe blunt ocular trauma. Design. Retrospective observational case series. Methods. Retinal oximetry was performed in both eyes of 29 patients with unilateral closed-globe blunt ocular trauma. Arterial oxygen saturation (SaO2), venous oxygen saturation (SvO2), arteriovenous difference in oxygen saturation (SO2), arteriolar diameter, venular diameter, and arteriovenous difference in diameter were measured. Association parameters including age, finger pulse oximetry, systolic pressure, diastolic pressure, and heart rate were analyzed. Results. The mean SaO2 in traumatic eyes (98.1% ± 6.8%) was not significantly different from SaO2 in unaffected ones (95.3% ± 7.2%) (p = 0.136). Mean SvO2 in traumatic eyes (57.1% ± 10.6%) was significantly lower than in unaffected ones (62.3% ± 8.4%) (p = 0.044). The arteriovenous difference in SO2 in traumatic eyes (41.0% ± 11.2%) was significantly larger than in unaffected ones (33.0% ± 6.9%) (p = 0.002). No significant difference was observed between traumatic eyes and unaffected ones in arteriolar (p = 0.249) and venular diameter (p = 0.972) as well as arteriovenous difference in diameter (p = 0.275). Conclusions. Oxygen consumption is increased in eyes after cgBOT, associated with lower SvO2 and enlarged arteriovenous difference in SO2 but not with changes in diameter of retinal vessels.

A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether there is any role for resuscitative emergency department thoracotomy in severe blunt trauma. Emergency thoracotomy is an accepted intervention for patients with penetrating cardiothoracic trauma. However, its role in blunt trauma has been challenged and has been a subject of considerable debate. Altogether, 186 relevant papers were identified, of which 14 represented the best evidence to answer the question. The author, journal, date, country of publication and relevant outcomes are tabulated. The 14 studies comprised 2 systematic reviews and 12 retrospective studies. The systematic review performed by the Trauma Committee of the American College of Surgeons included 42 studies and a cumulative total of 2193 blunt trauma patients who underwent an emergency department thoracotomy, reporting a survival rate of 1.6%. According to this review, 15% of the survivors suffered from neurological sequelae, but survivors from both penetrating and blunt trauma were included. A systematic review comprising 24 studies reported a survival rate of 1.4% among 1047 blunt trauma patients. Of the retrospective studies, 11 report poor survival rates, ranging from 0 to 6%. Only one study reports a higher survival rate (12.2%). Five of the studies reported on the neurological outcome of survivors. The majority of the studies suffered from limitations due to the small number of included cases. The reported survival after an emergency department thoracotomy for blunt trauma is very low in the vast majority of available studies. Furthermore, the neurological sequelae in the few survivors are frequent and severe. Interestingly, some author groups recommend that emergency department thoracotomy should be contraindicated in cases of blunt trauma with no signs of life at the scene of trauma or on arrival at the emergency department. Larger, well-designed series will

Objectives To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. Design A retrospective review. Setting A regional trauma unit in a tertiary-care institution. Patients Multiply injured trauma patients admitted between January 1988 and December 1990 who died within 24 hours of injury and in whom an autopsy was done. Intervention Standard radiography of the chest. Main Outcome Measures Chest injuries diagnosed and recorded by the trauma room team from standard anteroposterior x-ray films compared with the findings at autopsy and with review of the films by a staff radiologist initially having no knowledge of the injuries and later, if injuries remained undetected, having knowledge of the autopsy findings. Results Thirty-seven patients met the study criteria, and their cases were reviewed. In 11 cases, significant injuries were noted at autopsy and not by the trauma-room team, and in 7 cases these injuries were also missed by the reviewing radiologist. Injuries missed by the team were: multiple rib fractures (11 cases), sternal fractures (3 cases), diaphragmatic tear (2 cases) and intimal aortic tear (1 case). In five cases, chest tubes were not inserted despite the presence (undiagnosed) of multiple rib fractures and need for intubation and positive-pressure ventilation. Conclusions Significant blunt abdominal trauma, potentially requiring operative management or chest-tube insertion, may be missed on the initial anteroposterior chest x-ray film. Caution must therefore be exercised in interpreting these films in the trauma resuscitation room. PMID:8599789

The long-term consequences of blunt renal trauma are not well described. We report on 2 patients with a history of blunt renal trauma who presented with radiographically detected renal masses suspicious for renal tumor. Both patients suffered blows to the kidney during boxing matches followed by flank pain and hematuria. The injuries occurred 25 and 50 years prior to the detection of renal masses. Subsequent nephrectomy and histopathological evaluation revealed benign dystrophic renal tissue. These presentations represent probable long-term sequelae of blunt renal trauma.

Profunda femoris artery (PFA) pseudoaneurysm after blunt trauma without associated femur fracture is a rare occurrence. Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed to show any long bone fracture, CT angiography confirmed pseudoaneurysm of the branch of the PFA. Both patients were then treated with emergent coil embolization of the bleeding vessel. Pseudoaneurysms typically present late and signs of persistent hip pain, thigh swelling, presence of a pulsatile mass, and even unexplained anemia all may suggest the diagnosis. Recognition of PFA pseudoaneurysm requires high index of suspicion and is often difficult to diagnose clinically because of its location. PMID:28246563

Traumatic perforation of the cervical esophagus due to blunt trauma is a very rare condition which continues to be associated with significant mortality rates. The symptoms and signs of this injury are often masked by or ascribed to more common blunt thoracic injuries. This paper presents a case of cervical esophageal perforation secondary to blunt trauma resulting from a car accident. The injury was diagnosed early by computed tomography examination, and the patient underwent prompt and successful surgical repair performed to prevent the development of descending mediastinitis.

Gall bladder injuries are seen in 2% of patients undergoing laparotomy for blunt trauma abdomen. Isolated gall bladder injury is a rare event with associated presence of stones is even rarer. The associated visceral injuries lead to intraoperative identification in most cases. Here we present a case of 30 years old male with isolated gall bladder laceration following blunt abdominal trauma. The diagnosis of gallbladder perforation after blunt injury may be suspected in patients with signs of an acute abdomen and hypotension that is not explained by blood loss. Early suspicion and prompt exploration is imperative. Cholecystectomy is an adequate treatment for the condition.

We report the experience of a Level I trauma center in the management of blunt renal injury during a 5-year period, with special attention to those treated using angiography with embolization. The institutional trauma registry was queried for all patients with blunt renal injury between September 1, 2009 and August 30, 2014. Each injury was graded using the American Association for the Surgery of Trauma guidelines. Patients that underwent angiography with embolization were reviewed for case-specific information including imaging findings, treatment, materials used, clinical course, and mortality. The registry identified 48 blunt renal injury patients. Median Injury Severity Score was higher and hospital length of stay was significantly longer in those with blunt renal injury when compared with those without blunt renal injury (P < 0.001). The majority of patients with blunt renal injury were managed nonoperatively. Mortality was three out of 48 patients (5%). Nine patients underwent exploratory laparotomy. These operations were always performed for reasons other than the renal trauma (e.g., splenic injury, free fluid, free air). No patient underwent invasive renal operation. Six patients were treated using angiography with embolization. Of the six, one patient died of pulmonary septic complications. We conclude that selective nonoperative management is the mainstay of treatment for blunt renal injury. Angiography with embolization is a useful modality for cases of ongoing bleeding, and is typically preferable to nephrectomy in our experience.

Blunt thoracic trauma is a common occurrence in automobile accidents. Acute myocardial infarction (AMI) caused by coronary dissection following blunt thoracic trauma is rare. We report a case of healthy 24-year-old man with a history of blunt thoracic injury with subsequent undetected AMI who died of acute decompensated heart failure 4 days after the insult. The autopsy findings showed a 90% luminal narrowing of the left anterior descending coronary artery by dissecting hematoma, 3 cm in length. The myocardium revealed transmural myocardial infarction affecting apex, most part of left ventricular free wall, and interventricular septum. Both lungs were heavy, wet, and noncrepitant. Histological findings of the infarcted myocardium were consistent with 3-5 days post-AMI. Sections from both lungs revealed massive pulmonary edema, reflecting acute decompensated heart failure following a large AMI secondary to coronary dissection. Blunt thoracic trauma may obscure typical chest pain associated with cardiac ischemia especially in cases with a high tolerance for pain.
We report the case of a 69-year-old male patient who appeared in our clinic with persistent swelling on the right middle nasal bridge of 3 months' standing following blunt trauma. On physical examination the swelling was pulsatile and a flow was identified on color Doppler sonography. MRT of the head demonstrated an aneurysm of the dorsal nasal artery. We treated the aneurysm in an open surgical procedure under local anaesthesia. Due to the superficial position of this artery, open injuries are common after blunt nasal trauma. Some cases of aneurysm of the temporal artery have been described. Aneurysm of the dorsal nasal artery is a rare result of nasal trauma.

Gastrointestinal hollow viscus injury after blunt chest and abdominal trauma is uncommon and complicates 0.6%-1.2% of all cases of trauma. Early recognition of such injuries significantly decreases morbidity and mortality. Since physical examination is not accurate in detecting such injuries, contrast-enhanced computed tomography has been the mainstay for diagnosis in many emergency departments. This pictorial essay aims to review the incidence, mechanisms, and signs of gastrointestinal hollow viscus injuries in the setting of blunt chest and abdominal trauma.

Since the advent of percutaneous cardiopulmonary support (PCPS), its application has been extended to massively injured patient. Cardiac injury following blunt chest trauma brings out high mortality and morbidity. In our cases, patients had high injury severity score by blunt trauma and presented sudden hemodynamic collapse in emergency room. We quickly detected cardiac tamponade by focused assessment with sonography for trauma and implemented PCPS. As PCPS established, their vital sign restored and then, they were transferred to the operation room (OR) securely. After all injured lesion repaired, PCPS weaned successfully in OR. They were discharged without complication on day 26 and 55, retrospectively. PMID:23130310
Background Blunt carotid and vertebral artery injury (BCVI) occur infrequently. The incidence of this type of injury is difficult to determine as many emergency room patients are neurologically asymptomatic. The statistics have not been reported in Brazil. The objectives of the current study were: To evaluate the accuracy of criteria used to recommend angiotomography in the diagnosis of cervical BCVI in 100 patients with blunt cervical trauma in the trauma services section of a Brazilian quaternary care hospital. Methods During a 30-month (2006-2008), all patients admitted to the emergency room of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo with blunt cervical trauma and potential risk of cervical vessel injury, were subjected to cervical angiotomography to diagnose BCVI. The data analyzed are presented as mean ± standard deviation, and statistical analyses included Chi-square and Fisher's exact tests, and the Mann-Whitney test. Results During the study period 2467 blunt trauma patients were admitted. In 100 patients that met the criteria for inclusion in the study, angiotomography identified 23 with BCVI, including 17 males and six females. The mean patient age was 34.81 ± 14.84 years. Car crash (49%) and car-pedestrian accidents (24%) were the most frequent causes of injury. Ten patients had internal carotid artery injuries, two patients had common carotid artery injuries, and 11 patients had vertebral artery injuries. Seven patients presented with Degree I arterial injuries, 10 patients presented with Degree II artery injuries, four patients presented with Degree IV artery injuries, one patient presented with a Degree V artery injury, and one patient had a carotid fistula. Seven out of the 23 patients with BCVI (30.4%) presented with cervical vertebrae fractures, and 11 out of the 23 patients with BCVI (47.8%) presented with facial fractures (LeFort II and III). Conclusions Although there is no consensus regarding the criteria

Intraosseous venous access can be life-saving in trauma patients when traditional methods for obtaining venous access are difficult or impossible. Because many blunt trauma patients require expeditious evaluation by computed tomography (CT) scans with intravenous contrast, it is important to evaluate whether intraosseous catheters can be used for administering CT contrast agents in lieu of waiting until secure peripheral intravenous or central venous catheter access can be established. Previous case reports have demonstrated that tibial intraosseous catheters can be used to safely administer CT contrast in the pediatric patient population. Here we report a case in which intraosseous access was the only means of administering intravenous contrast agent in an adult blunt trauma patient. An intraosseous catheter was placed in the standard manner in the right proximal humerus. Intravenous contrast agent was administered through the intraosseous catheter, using the standard blunt trauma protocol at our institution. CT scans were evaluated by a staff radiologist and assessed for the adequacy of diagnosis for blunt traumatic injuries. CT scans of the thorax, abdomen, and pelvis were considered to be adequate for diagnostic purposes and subjectively equivalent to those of studies using traditional central venous access. The intraosseous catheter was discontinued the following day. No complications of intraosseous placement or of contrast administration were identified. Intraosseous catheterization appears to be a feasible and effective alternative to traditional methods of venous access in the administration of iodinated contrast agents for CT evaluation in adult blunt trauma patients. Further study is warranted.

A 65-year-old male developed acute myocardial infarction due to coronary artery dissection and tricuspid valve injury after blunt chest trauma. Acute myocardial infarction was treated by coronary artery intervention; however, refractory heart failure with pleural effusion remained. The first transthoracic echocardiography (TTE) on admission failed to clearly visualize the tricuspid valve and right ventricle due to poor image quality. A follow-up TTE with contrast ultrasonography revealed pericardial rupture in addition to tricuspid regurgitation. Ruptures of the tricuspid papillary muscle and pericardium were confirmed during surgery and were repaired successfully. Blunt chest trauma results in various cardiac injuries including cardiac rupture, intramural hematoma, valvular injury, coronary artery injury, and electrical disturbances, leading to critical conditions and high mortality. Of such blunt trauma-induced injuries, coronary artery dissection, tricuspid valve injury, and pericardial rupture caused by blunt chest trauma are rare, and simultaneous occurrence of the three types of injuries that were successfully repaired has not been reported. In addition, this case indicates the utility of contrast ultrasonography for diagnosis of pericardial rupture caused by blunt chest trauma.

Testicular rupture, one of the most common complications in blunt scrotal trauma, is the rupture of tunica albuginea and extrusion of seminiferous tubules. Testicular rupture is more inclined to young men, and injury mechanisms are associated with sports and motor accidents. After history taking and essential physical examination, scrotal ultrasound is the first-line auxiliary examination. MRI is also one of the vital complementary examinations to evaluate testicular rupture after blunt scrotal trauma. Surgical exploration and repair may be necessary when the diagnosis of testicular rupture is definite or suspicious. Postoperative follow-up is to monitor the relief of local symptoms and changes of testicular functions. This review sums up the literatures about testicular rupture after blunt scrotal trauma in recent 16 years and also refers some new advantages and perspectives on diagnosis and management of testicular rupture.

Purpose This study aims to examine the current management strategies and outcomes after blunt pancreatic trauma in children using a national patient registry. Methods Using the National Trauma Data Bank (NTDB) from 2007–2011, we identified all patients ≤18 years old who suffered blunt pancreatic trauma. Patients were categorized as undergoing nonoperative pancreatic management (no abdominal operation, abdominal operation without pancreatic-specific procedure, or pancreatic drainage alone) or operative pancreatic management (pancreatic resection/repair). Patient characteristics, operative details, clinical outcomes, and factors associated with operative management were examined. Results Of 610,402 pediatric cases in the NTDB, 1653 children (0.3%) had blunt pancreatic injury and 674 had information on specific location of pancreatic injury. Of these 674 cases, 514 (76.3%) underwent nonoperative pancreatic management. The groups were similar in age, gender, and race; however, pancreatic injury grade > 3, moderate to severe injury severity, and bicycle accidents were associated with operative management in multivariable analysis. Children with pancreatic head injuries or GCS motor score < 6 were less likely to undergo pancreatic operation. Overall morbidity and mortality rates were 26.5% and 5.3%, respectively. Most outcomes were similar between treatment groups, including mortality (2.5% vs. 6.7% in operative vs. nonoperative cohorts respectively; p = 0.07). Conclusion Although rare, blunt pancreatic trauma in children continues to be a morbid injury. In the largest analysis of blunt pancreatic trauma in children, we provide data on which to base future prospective studies. Operative management of pancreatic trauma occurs most often in children with distal ductal injuries, suggesting that prospective studies may want to focus on this group. PMID:27577183

Renal artery pseudoaneurysm is a very rare complication after blunt trauma injury. We report on a case of a 54-year-old man admitted to our hospital for right flank pain and gross hematuria, 5 days after blunt abdominal trauma. The diagnosis of interlobar renal pseudoaneurysm was established by a computed tomography scan and confirmed by angiography. Successful superselective angioembolization was performed. This radiographic intervention is an effective and minimally invasive technique to stop active bleeding from renal artery pseudoaneurysms, when patients are hemodynamically stable and where technically feasible. A review of the literature was carried out. PMID:24809039

The spleen is the most commonly injured abdominal organ in children who sustain blunt abdominal trauma, and pediatric splenic injury may result from minor mechanisms of injury, including sports participation. We present 2 cases of splenic injury in soccer goalies because of blunt abdominal trauma sustained during game play. Although abdominal organ injuries are uncommon in soccer, emergency medicine and primary care physicians must be aware of the possibility. A high index of suspicion and careful physical examination are key in making the diagnosis.

Blunt cerebrovascular injuries (BCVI) carry significant morbidity if not diagnosed and treated early. A high index of clinical suspicion is needed to recognize the injury patterns associated with this condition and to order the requisite imaging studies needed to diagnose it accurately. We report of BCVI associated with a congenital cervical spine malformation after blunt trauma. We recommend inclusion of cervical spine malformations to the current Eastern Association for the Surgery of Trauma screening criteria for BCVI and explain our rationale for the same.

Serious blunt scrotal trauma in the pediatric population is rare and can pose significant danger to the viability of the testes. The following case describes an adolescent boy who presented with a single testis in his scrotum after low-impact perineal trauma, consistent with testicular dislocation. The literature regarding scrotal trauma includes few cases of testicular dislocation from low-impact perineal trauma. Included is a brief review of the most recent data including epidemiology, differential diagnosis, acute management, and complications pertinent to the pediatric emergency clinician.

Introduction Soft tissue injuries are relatively common after blunt neck trauma, because of its complex anatomy, many vital structures can be compromised. Isolated trauma to the thyroid is highly uncommon and there are few cases reported in the literature. Presentation of case A 19 year-old female patient with no known pathologies who sustained direct blunt trauma to the right frontal half of the neck after falling down from a stair case. She arrived at the ER with moderate neck swelling and pain. There were no visible hematomas and no respiratory compromise was noted. Contrast enhanced CT-scan showed rupture and hematoma of the right thyroid lobe; she underwent surgical exploration with hemi thyroidectomy and recovered uneventfully. Discussion Despite soft tissue injuries are relatively common after blunt neck trauma, isolated thyroid gland injury is extremely rare and is present in about 1–2% of the cases and in most of the cases there is an underlining pathology within the gland. Most patients arrived at the emergency room hemodynamically stable, presenting neck swelling, pain, respiratory distress, dysphagia and hoarseness. Diagnosis strategy should be focused to rule out respiratory or vascular compromise. Surgical exploration remains the most common treatment strategy. Conclusions Although the rarity of this condition, physicians should take in mind the possibility of thyroid injury after blunt neck trauma. Early detection and prompt treatment, can reduce life threatening complications. Management should be individualized to patient’s characteristics and surgeon’s experience. PMID:26001363

Study Design Retrospective comparative study. Objective To compare strict Biffl criteria to more-liberal criteria for computed tomography angiography (CTA) when screening for blunt cerebrovascular injury (BCVI). Methods All CTAs performed for blunt injury between 2009 and 2011 at our institution were reviewed. All patients with cervical spine fractures who were evaluated with CTA were included; patients with penetrating trauma and atraumatic reasons for imaging were excluded. We then categorized the patients' fractures based on the indications for CTA as either within or outside Biffl criteria. For included subjects, the percentage of studies ordered for loose versus strict Biffl criteria and the resulting incidences of BCVI were determined. Results During our study period, 1,000 CTAs were performed, of which 251 met inclusion criteria. Of the injuries, 192 met Biffl criteria (76%). Forty-nine were found to have BCVIs (19.5%). Forty-one injuries were related to fractures meeting Biffl criteria (21.4%), and 8 were related to fractures not meeting those criteria (13.6%). The relative risk of a patient with a Biffl criteria cervical spine injury having a vascular injury compared with those imaged outside of Biffl criteria was 1.57 (p = 0.19). Conclusions Our data demonstrates that although cervical spine injuries identified by the Biffl criteria trend toward a higher likelihood of concomitant BCVI (21.4%), a significant incidence of 13.6% also exists within the non-Biffl fracture cohort. As a result, a more-liberal screening than proposed by Biffl may be warranted. PMID:27781188

Leadership skills of senior residents, trauma fellows, and a nurse practitioner were assessed during simulation training for the initial management of blunt trauma. This was a pilot, observational study, that in addition to skill development and assessment also sought to determine the need for a dedicated leadership training course for surgical residents. The study evaluated the leadership skills and adherence to Advance Trauma Life Support (ATLS) guidelines of the team leaders during simulation training. The team leaders' performances on criteria regarding prearrival planning, critical actions based on ATLS, injury identification, patient management, and communication were evaluated for each of five blunt-trauma scenarios. Although there was a statistically significant increase in leadership skills for performing ATLS critical actions, P < 0.05, there were 10 adverse events. A structured simulation program dedicated to developing skills for team leadership willbe a worthwhile endeavor at our institution.

We report four cases of occult pneumothorax in patients who had suffered blunt trauma. In each case supine chest X-rays failed to diagnose an anterior pneumothorax. Subsequent spiral computerised tomography scans of the chest showed anterior pneumothoraces in all cases. In two of the cases anterior pneumothoraces were present in spite of a chest drain having been placed in the pleural cavity. We recommend the insertion of anteriorly positioned chest drains to relieve pneumothoraces in severely injured trauma patients.

Abdominal trauma is responsible for most genitourinary injuries. The incidence of renal artery injury and intrathoracic kidney is quite low in patients who present with blunt trauma experiencing damage. There are four defined etiologies for intrathoracic kidney, which include real intrathoracic ectopic kidney, eventration of the diaphragm, congenital diaphragmatic herniation, and traumatic diaphragmatic rupture. The traumatic intrathoracic kidney is an extremely rare case. We presented intrathoracic kidney case after traumatic posterior diaphragmatic rupture. PMID:26881170

The blunt trauma performance of fabric systems against 9 mm bullets is reported. Three shots were fired at each fabric system with impact velocity of 367±9 m/s and the depth of indentation on the modeling clay backing was measured. The results showed that 18-layer and 21-layer all-neat fabric systems failed the blunt trauma test. However, fabric systems with natural rubber (NR) latex coated fabric layers gave lower blunt trauma of between 25-32 mm indentation depths. Deformations on the neat fabrics upon impact were identified as broken yarns, yarn stretching and yarn pull-out. Deflections of the neat fabrics were more localised. For the NR latex coated fabric layers, no significant deformation can be observed except for peeled-off regions of the NR latex film at the back surface of the last layer. From the study, it can be said that the NR latex coated fabric layers were effective in reducing the blunt trauma of fabric systems.

A posttraumatic diaphragmatic hernia was diagnosed by ultrasound and x-ray examinations 1 year after a blunt trauma of the chest and abdomen. The diaphragmatic lesion could be seen retrospectively in the initial sonograms which were performed during the acute illness. It was however not possible to confirm the rupture during laparatomy.

Vehicle collisions represent more than 75% of mechanism of blunt abdominal trauma. In spite of the incomparable improvement of car safety devices, recent studies pointed out that the air bags might cause injuries, specially when it is not associated with seatbelt. In fact, some studies pointed out that crash victims using air bags alone have increased injury severity, hospitalisations, thoracoabdominal procedure, and rehabilitation. Some of the most frequently injured organs reported from air bag deployment are the liver (38%), the spleen (23%) and digestive system (17%). Injury of the hollow viscera are far less common. In particular, blunt abdominal trauma resulting in small bowel perforation is an infrequent lesion. These injuries are difficult to diagnose because specific signs are poor and a delay in treatment increases mortality and morbidity of the patients. We describe a case of thoracoabdominal trauma that occurred during a head-on collision after an air bag deployment without seatbelt use.

Introduction Delayed bile leak following blunt liver trauma is not common. Presentation of case We presented a case report and literature review of delayed bile leak in a young male patient who presented with grade IV blunt liver injury following a motor vehicle collision; he was a restrained driver who hit a fixed object. Physical examination was unremarkable except for revelaed tachycardia, right upper quadrant abdominal tenderness, and open left knee fracture. A diagnosis of grade IV multiple liver lacerations with large hemo-peritoneum was made and urgent exploratory laparotomy was performed. The patient developed a biloma collection post- operatively. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct stenting. His recovery was uneventful, and he was discharged home after 1 month. Discussion This is a rare case with no intra or extra hepatic biliary radicle injury seen on magnetic resonance cholangiopancreatography (MRCP) and no evidence of leak by ERCP. A review of the literature to highlight the incidence of delayed bile leak revealed only few reported cases. Conclusion Our findings demonstrate the need for prompt diagnosis and treatment of delayed bile leak in blunt liver injuries. When these principles are followed, a successful outcome is possible.

Negli ultimi 20 anni il trattamento del trauma epatico chiuso si è modificato radicalmente passando da una gestione quasi costantemente chirurgica ad una non operativa in tutti i casi in cui non vi siano le condizioni di instabilità emodinamica o di variazione nella clinica del paziente traumatizzato. A tutt’oggi però non è raro osservare un approccio a tale condizione clinica seguendo criteri che la Medicina Basata sull’Evidenza dimostra essere superati. Presentiamo in questo lavoro il caso clinico di una donna di 34 anni che subiva un trauma diretto della regione postero-laterale dell’emitorace destro cadendo accidentalmente da una scala. Nonostante la gravità della lesione evidenziata dalla TC (IV grado secondo AAST Liver Injury Scale), si è optato per un trattamento non operativo data la condizione di stabilità emodinamica ottenuta con un primo bolo di cristalloidi. Una complicanza di tipo respiratorio ha complicato il quadro in terza giornata dal trauma richiedendo una toracentesi e dei cicli di ventilazione non invasiva. A 4 anni di distanza dal trauma la paziente sta bene e non lamenta disturbi. La letteratura mostra che il trattamento conservativo viene impiegato oggi in oltre l’85% dei traumi epatici, indipendentemente dall’entità della lesione. Il successo del trattamento conservativo varia nelle diverse casistiche dall’82% al 100% dei casi, e le sue complicanze, quando si verificano (14% dei traumi maggiori) possono spesso essere trattate con procedure di radiologia interventistica, evitando ancora l’intervento chirurgico. Oggi, in assenza di altre lesioni addominali che richiedano l’esplorazione chirurgica, l’indicazione al trattamento operativo è solo l’instabilità emodinamica del paziente che persiste o si ripresenta subito dopo un corretto trattamento rianimatorio iniziale.

The treatment of isolated sternal fractures (ISF) throughout the world is heterogeneous. This study aimed to identify the incidence, morbidity, and mortality associated with isolated fractures of the sternum and describe current practice for diagnosis and management of ISF and cardiac injury at a level I trauma center in the UK. A retrospective cohort study of adult patients (>16 years) with ISF presenting from 2006 to 2010 was conducted. Eighty-eight patients with ISF were identified. Most patients (88%, 77) were admitted to hospital with 66% (58) of them discharged within 48 hours. Two (2%) patients had an ER EKG with abnormality but both resolved to normal sinus rhythm within 6 hours of follow-up. Serum CEs were drawn from 55 (63%) patients with only 2 (2%) having a rise in serum troponin >0.04; however, in both of these patients troponin quickly normalized. Six (7%) patients underwent echocardiograms without significant findings. In all 88 patients with ISF, no cases of clinically significant cardiac injury were identified. Patients presenting with an isolated sternal fracture with no changes on EKG or chest X-ray do not warrant an admission to hospital and may be discharged from the ER. PMID:24653859

Summary Background Blunt abdominal trauma is routinely encountered in the Emergency Department. It is one of the main causes of morbidity and mortality amongst the population below the age of 35 years worldwide. Renal artery injury secondary to blunt abdominal trauma however, is a rare occurrence. Here, we present two such cases, encountered in the emergency department sustaining polytrauma following motor vehicle accidents. Case Report We hereby report two interesting cases of renal artery injury sustained in polytrauma patients. In these two cases we revealed almost the entire spectrum of findings that one would expect in renal arterial injuries. Conclusions Traumatic renal artery occlusion is a rare occurrence with devastating consequences if missed on imaging. Emergency radiologists need to be aware of the CT findings so as to accurately identify renal artery injury. This case report stresses the need for immediate CT assessment of polytrauma patients with suspected renal injury, leading to timely diagnosis and urgent surgical or endovascular intervention.

Introduction: Focused assessment with sonography for trauma (FAST) is a highly effective first screening tool for initial classification of abdominal trauma patients. The present study was designed to evaluate the outcome of patients with blunt abdominal trauma and positive FAST findings. Methods: The present prospective cross-sectional study was done on patients over 7 years old with normal abdominal examination, positive FAST findings, and available abdominopelvic computed tomography (CT) scan findings. The frequency of need for laparotomy as well as its probable risk factors were calculated. Results: 180 patients were enrolled (mean age: 28.0 ± 11.5 years; 76.7% male). FAST findings were confirmed by abdominopelvic CT scan in only 124 (68.9%) cases. Finally, 12 (6.6%) patients needed laparotomy. Mean age of those in need of laparotomy was significantly higher than others (36.75 ± 11.37 versus 27.34 ± 11.37, p = 0.006). Higher grading of spleen (p = 0.001) and hepatic (p = 0.038) ruptures increased the probability of need for laparotomy. Conclusion: 68.9% of the positive FAST findings in patients with blunt abdominal trauma and stable hemodynamics was confirmed by abdominopelvic CT scan and only 6.6% needed laparotomy. Simultaneous presence of free fluid and air in the abdominal area, old age, and higher grading o solid organ injuries were factors that had a significant correlation with need for laparotomy.

Non-penetrating chest trauma commonly causes a wide variety of cardiac injuries. Disruption of the aortic valve with resultant aortic regurgitation is not uncommon; conversely, a sinus of Valsalva-right atrial fistula, in the absence of a congenital sinus of Valsalva aneurysm, has been reported only once previously. This report describes the detection by preoperative cardiac catheterisation of both aortic regurgitation, and a sinus of Valsalva-right atrial fistula after blunt chest trauma, and its surgical management. The need for preoperative cardiac catheterisation in patients suffering from non-penetrating cardiac trauma is emphasised, even when the diagnosis appears cleas, because of the diverse nature and possible multiplicity of cardiac lesions.

Objectives To determine what proportion of abdominal computed tomography (CT) scans ordered after blunt trauma are positive and the applicability and accuracy of existing clinical prediction rules for obtaining a CT scan of the abdomen in this setting. Setting A leading trauma hospital, affiliated with the University of Ottawa. Design A retrospective cohort study. Patients and methods All patients with blunt trauma admitted to hospital over a 1-year period having an Injury Severity Score (ISS) greater than 12 who underwent CT of the abdomen during the initial assessment. Recorded data included age, sex, Glasgow Coma Scale (GCS) score, ISS, type of injuries, number of abdominal CT scans ordered, and scan results. Two clinical prediction rules were found in the literature that identify patients likely to have intra-abdominal injuries. These rules were applied retrospectively to the cohort. The predicted proportion of positive CT scans was compared with the observed proportion, and the sensitivity, specificity, and accuracy were estimated. Results Of the 297 patients entered in the study, 109 underwent abdominal CT. The median age was 32 years, 71% were male and the median ISS was 24. In only 36.7% (40 of 109) of scans were findings suggestive of intra-abdominal injuries. Application of one of the clinical prediction rules gave a sensitivity of 93.8% and specificity of 25.5% but excluded 23% of patients because of a GCS score less than 11. The second prediction rule tested could be applied to all patients and was highly sensitive (92.5%) and specific (100.0%). Conclusions The assessment of the abdomen in blunt trauma remains a challenge. Accuracy in predicting positive scans in equivocal cases is poor. Retrospective application of an existing clinical prediction rule was found to be highly accurate in identifying patients with positive CT findings. Prospective use of such a rule could reduce the number of CT scans ordered without missing significant injuries. PMID

A number of armed assaults on public officials occurred in the early 1970s, which prompted the Lightweight Soft Body Armor Program to develop modern, concealable, soft body armor. Methodology needed to be developed to (1) determine the effectiveness of the soft body armor to stop bullet penetration and (2) assess the potential injury from nonpenetrating blunt impacts to the body. Extensive research was performed under the program to develop methodologies to assess soft body armor, including behind-armor blunt trauma (BABT) evaluation. This methodology is still used today, and it has been applied extensively beyond the original intent. However, the origin of this methodology is not well understood by many researchers in the various fields in which it is being applied because the original documentation is difficult to obtain. Therefore, the purpose of this article is to provide a comprehensive review of the BABT to offer researchers information about its history and limitations.

The MRI-based computational model, previously validated by tagged MRI and HARP imaging analysis technique on in vivo human brain deformation, is employed to study transient wave dynamics during blunt head trauma. Three different constitutive models are used for the cerebrospinal fluid (CSF): incompressible solid elastic, viscoelastic and fluid-like elastic using an equation of state model. Three impact cases are simulated which indicate that the blunt impacts give rise not only to a fast pressure wave but also to a slow, and potentially much more damaging, shear (distortional) wave that converges spherically towards the brain center. The wave amplification due to spherical geometry is balanced by damping due to tissues' viscoelasticity and the heterogeneous brain structure, suggesting a stochastic competition of these two opposite effects. It is observed that this convergent shear wave is dependent on the constitutive property of the CSF whereas the peak pressure is not as significantly affected.
Introduction Computed tomography is commonly used to exclude occult injuries in patients with trauma, but imaging can reveal findings that are of uncertain etiology or clinical significance. We present a case of unsuspected pancreatic abnormality in a female patient with trauma who sustained an isolated blunt head injury. Case presentation A 25-year-old female Caucasian patient sustained massive blunt and penetrating head trauma, secondary to a large object penetrating through the vehicle windshield. Based on the mechanism of injury and clinical evaluation, it was felt to be an isolated head injury. However, computed tomography of her abdomen revealed an occult, intra-abdominal finding of significant pancreatic enlargement and peripancreatic fluid. There was no computed tomography evidence of parenchymal pancreatic laceration. The appearance of her pancreas on computed tomography was identical to that of acute pancreatitis or low-grade pancreatic injury, but her clinical history and laboratory values were not consistent with this, hence the term ‘pseudopancreatitis’. Later surgery for organ donation confirmed diffuse pancreatic and peripancreatic edema, but no hematoma, contusion or other evidence for direct traumatic injury. This was an isolated intra-abdominal abnormality. Conclusion The routine use of computed tomography in patients who have sustained trauma has led to increasing detection of unexpected findings. Clinical information such as mechanism of injury and blood work, along with careful evaluation of ancillary imaging findings (or lack of), is important for the provision of an appropriate differential diagnosis. We discuss the possible mechanism and differential diagnosis of an isolated pancreatic abnormality in the setting of non-abdominal trauma, which includes shock pancreas, overhydration, traumatic pancreatic injury and pancreatitis secondary to other etiologies.

To investigate the importance of route of nutrient administration on septic complications after blunt and penetrating trauma, 98 patients with an abdominal trauma index of at least 15 were randomized to either enteral or parenteral feeding within 24 hours of injury. Septic morbidity was defined as pneumonia, intra-abdominal abscess, empyema, line sepsis, or fasciitis with wound dehiscence. Patients were fed formulas with almost identical amounts of fat, carbohydrate, and protein. Two patients died early in the study. The enteral group sustained significantly fewer pneumonias (11.8% versus total parenteral nutrition 31.%, p less than 0.02), intra-abdominal abscess (1.9% versus total parenteral nutrition 13.3%, p less than 0.04), and line sepsis (1.9% versus total parenteral nutrition 13.3%, p less than 0.04), and sustained significantly fewer infections per patient (p less than 0.03), as well as significantly fewer infections per infected patient (p less than 0.05). Although there were no differences in infection rates in patients with injury severity score less than 20 or abdominal trauma index less than or equal to 24, there were significantly fewer infections in patients with an injury severity score greater than 20 (p less than 0.002) and abdominal trauma index greater than 24 (p less than 0.005). Enteral feeding produced significantly fewer infections in the penetrating group (p less than 0.05) and barely missed the statistical significance in the blunt-injured patients (p = 0.08). In the subpopulation of patients requiring more than 20 units of blood, sustaining an abdominal trauma index greater than 40 or requiring reoperation within 72 hours, there were significantly fewer infections per patient (p = 0.03) and significantly fewer infections per infected patient (p less than 0.01). There is a significantly lower incidence of septic morbidity in patients fed enterally after blunt and penetrating trauma, with most of the significant changes occurring in the

We induced mild blunt and blast injuries in rats using a custom-built device and utilized in-house diffusion tensor imaging (DTI) software to reconstruct 3-D fiber tracts in brains before and after injury (1, 4, and 7 days). DTI measures such as fiber count, fiber length, and fractional anisotropy (FA) were selected to characterize axonal integrity. In-house image analysis software also showed changes in parameters including the area fraction (AF) and nearest neighbor distance (NND), which corresponded to variations in the microstructure of Hematoxylin and Eosin (H&E) brain sections. Both blunt and blast injuries produced lower fiber counts, but neither injury case significantly changed the fiber length. Compared to controls, blunt injury produced a lower FA, which may correspond to an early onset of diffuse axonal injury (DAI). However, blast injury generated a higher FA compared to controls. This increase in FA has been linked previously to various phenomena including edema, neuroplasticity, and even recovery. Subsequent image analysis revealed that both blunt and blast injuries produced a significantly higher AF and significantly lower NND, which correlated to voids formed by the reduced fluid retention within injured axons. In conclusion, DTI can detect subtle pathophysiological changes in axonal fiber structure after mild blunt and blast trauma. Our injury model and DTI method provide a practical basis for studying mild traumatic brain injury (mTBI) in a controllable manner and for tracking injury progression. Knowledge gained from our approach could lead to enhanced mTBI diagnoses, biofidelic constitutive brain models, and specialized pharmaceutical treatments.

In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients. PMID:26147725

Objective: To determine the presentation, anatomical distribution, diagnostic method, management and outcome of hollow viscus injury (HVI) from blunt abdominal trauma. Methods: This was a retrospective cross-ecnal study including patients with blunt abdominal trauma leading to HVI admitted at Rajendra Institute of Medical Sciences, Ranchi, over a period of 4.5 years (January 2009 to July 2014). Data were retrieved from patients’ medical records. Total 173 patients with HVI due to blunt abdominal trauma, who underwent laparotomy at our institute, were reviewed. Data regarding clinical presentation, anatomical distribution, management and outcome were recorded and analysed. Results: Out of 173 patients 87.1% were men and 12.9% were women. Mean age of patients was 29±14.02 years. The most common site of injury was ileum (46.2%) followed by jejunum (44.5%). There were 5 gastric perforations (2.9%), 2 (1.15%) duodenal, 2 (1.15%) colonic, 2 (1.15%) sigmoidal and 2 (1.15%) rectal injuries. One caecal injury was also recorded. Road traffic accident was the most common mechanism of injury (57.2%) followed by fall from height (36.4%) and assault (6.4%). Free gas under diaphragm on erect abdomen radiography was seen in 85.5% of cases while preoperative CT Abdomen was done in 11.6% of cases. Treatment consisted of simple closure of the perforation (66.5%), resection and anastomosis (11.0%) and stoma (22.5%). Major complication was anastamotic leak which was recorded in 6.4% cases and 15.6% patients developed burst abdomen. Average hospital stay was 13±6 days. Overall mortality rate was 12.7%. Conclusion: Although early recognition of intestinal injuries from blunt abdominal trauma may be difficult in all cases, it is very important due to its tremendous life threatening potential. Age of the patient, anatomical site and time of presentation are probably main prognostic factors. PMID:27162889

Abstract We aimed to compare the diagnostic performance and inter-observer consistency between low dose chest CT (LDCT) and standard dose chest CT (SDCT) in the patients with blunt chest trauma. A total of 69 patients who met criteria indicative of blunt chest trauma (77% of male; age range, 16–85) were enrolled. All patients underwent LDCT without intravenous (IV) contrast and SDCT with IV contrast using parameters as following: LDCT, 40 mAs with automatic tube current modulation (ATCM) and 100 kVp (BMI <25, n = 51) or 120 kVp (BMI>25, n = 18); SDCT, 180 mAs with ATCM and 120 kVp. Transverse, coronal, sagittal images were reconstructed with 3-mm slice thickness without gap and provided for evaluation of 3 observers. Reference standard images (transverse, coronal, sagittal) were reconstructed using SDCT data with 1-mm slice thickness without gap. Reference standard was established by 2 experienced thoracic radiologists by consensus. Three observers independently evaluated each data set of LDCT and SDCT. Multiple-reader receiver operating characteristic analysis for comparing areas under the ROC curves demonstrated that there was no significant difference of diagnostic performance between LDCT and SDCT for the diagnosis of pulmonary injury, skeletal trauma, mediastinal injury, and chest wall injury (P > 0.05). The intraclass correlation coefficient was measured for inter-observer consistency and revealed that there was good inter-observer consistency in each examination of LDCT and SDCT for evaluation of blunt chest injury (0.8601–1.000). Aortic and upper abdominal injury could not be appropriately compared as LDCT was performed without using contrast materials and this was limitation of this study. The effective radiation dose of LDCT (average DLP = 1.52 mSv⋅mGy−1 cm−1) was significantly lower than those of SDCT (7.21 mSv mGy−1 cm−1). There is a great potential benefit to use of LDCT for initial evaluation of blunt chest trauma

Atomistic simulations based on interatomic potentials have frequently failed to correctly reproduce the brittle fracture of materials, showing an unrealistic blunting. We analyse the origin of the unrealistic blunting during atomistic simulations by modified embedded-atom method (MEAM) potentials for experimentally well-known brittle materials such as bcc tungsten and diamond silicon. The radial cut-off which has been thought to give no influence on MEAM calculations is found to have a decisive effect on the crack propagation behaviour. Extending both cut-off distance and truncation range can prevent the unrealistic blunting, reproducing many well-known fracture behaviour which have been difficult to reproduce. The result provides a guideline for future atomistic simulations that focus on various fracture-related phenomena including the failure of metallic-covalent bonding material systems using MEAM potentials.

A Human Head Surrogate has been developed for use in behind helmet blunt trauma experiments. This human head surrogate fills the void between Post-Mortem Human Subject testing (with biofidelity but handling restrictions) and commercial ballistic head forms (with no biofidelity but ease of use). This unique human head surrogate is based on refreshed human craniums and surrogate materials representing human head soft tissues such as the skin, dura, and brain. A methodology for refreshing the craniums is developed and verified through material testing. A test methodology utilizing these unique human head surrogates is also developed and then demonstrated in a series of experiments in which non-perforating ballistic impact of combat helmets is performed with and without supplemental ceramic appliques for protecting against larger caliber threats. Sensors embedded in the human head surrogates allow for direct measurement of intracranial pressure, cranial strain, and head and helmet acceleration. Over seventy (70) fully instrumented experiments have been executed using this unique surrogate. Examples of the data collected are presented. Based on these series of tests, the Southwest Research Institute (SwRI) Human Head Surrogate has demonstrated great potential for providing insights in to injury mechanics resulting from non-perforating ballistic impact on combat helmets, and directly supports behind helmet blunt trauma studies.

The aim of this study was to assess radiomorphologic and clinical features of tracheal rupture due to blunt chest trauma. From 1992 until 1998 the radiomorphologic and clinical key findings of all consecutive tracheal ruptures were retrospectively analyzed. The study included ten patients (7 men and 3 women; mean age 35 years); all had pneumothoraces which were persistent despite suction drainage. Seven patients developed a pneumomediastinum as well as a subcutaneous emphysema on conventional chest X-rays. In five patients, one major hint leading to the diagnosis was a cervical emphysema, discovered on the lateral cervical spine view. Contrast-media-enhanced thoracic CT was obtained in all ten cases and showed additional injuries (atelectasis n = 5; lung contusion n = 4; lung laceration n = 2; hematothorax n = 2 and hematomediastinum n = 4). The definite diagnosis of tracheal rupture was made by bronchoscopy, which was obtained in all patients. Tracheal rupture due to blunt chest trauma occurs rarely. Key findings were all provided by conventional chest X-ray. Tracheal rupture is suspected in front of a pneumothorax, a pneumomediastinum, or a subcutaneous emphysema on lateral cervical spine and chest films. Routine thoracic CT could also demonstrate these findings but could not confirm the definite diagnosis of an tracheal rupture except in one case; in the other 9 cases this was done by bronchoscopy. Thus, bronchoscopy should be mandatory in all suspicious cases of tracheal rupture and remains the gold standard.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an electrophysiological disorder of a physically normal heart that occurs in children when the body is subjected to intense emotional or physical stress that causes adrenergic discharge. This troubling disease can be sporadic (spontaneous) or familial (genetic/inherited). Unfortunately, its associated ventricular tachycardia may cause sudden death, so early diagnosis of CPVT is very important. Treatment modalities include medical treatment, implantation of a cardioverter defibrillator, or surgical sympatectomy; but the implantable cardioverter defibrillator (ICD) should be the first choice in patients with a history of cardiac arrest. We herein present the case of a patient diagnosed with CPVT after a successful cardiopulmonary resuscitation triggered by blunt chest trauma. We implanted an implantable cardioverter defibrillator and started oral B-blocker treatment. During the course of follow-up, flecainide was added to his treatment depending on the patient’s status regarding recurrent ICD shock. The patient has now continued follow-up without recurrent ICD shock since flecainide treatment was initiated. In conclusion, in patients with syncope and sudden cardiac arrest secondary to physical stress or blunt chest trauma, CPVT should be considered and an implantable cardioverter defibrillator must be implanted. Additionally, flecainide theraphy should be considered to decrease recurrent ICD shock. PMID:27122894

The aim of this study was to investigate the efficiency of domestic physician-staffed helicopter emergency medical service (HEMS) for the transport of patients with severe trauma to a hospital. The study included patients with blunt trauma who were transported to our hospital by physician-staffed HEMS (Group P; n = 100) or nonphysician-staffed HEMS (Group NP; n = 80). Basic patient characteristics, transport time, treatment procedures, and medical treatment outcomes assessed using the Trauma and Injury Severity Score (TRISS) were compared between groups. We also assessed patients who were transported to the hospital within 3 h of injury in Groups P (Group P3; n = 50) and NP (Group NP3; n = 74). The severity of injury was higher, transport time was longer, and time from hospital arrival to operation room transfer was shorter for Group P than for Group NP (P < 0.001). Although Group P patients exhibited better medical treatment outcomes compared with Group NP, the difference was not statistically significant (P = 0.134 vs. 0.730). However, the difference in outcomes was statistically significant between Groups P3 and NP3 (P = 0.035 vs. 0.546). Under the current domestic trauma patient transport system in South Korea, physician-staffed HEMS are expected to increase the survival of patients with severe trauma. In particular, better treatment outcomes are expected if dedicated trauma resuscitation teams actively intervene in the medical treatment process from the transport stage and if patients are transported to a hospital to receive definitive care within 3 hours of injury.

Between June 1, 1976 and June 30, 1989 The Regional Trauma Unit at Sunnybrook Medical Centre in Toronto, Ontario, Canada received 3730 patients. Of these 335 (9%) sustained a liver injury, 95% being due to blunt trauma. Open peritoneal lavage was performed on 80% of liver trauma patients (267/335), 99% being true positive. A laparotomy was performed on 97% of patients (324/335). Major surgical treatment was required in 132 patients (41%) and minor treatment in 192 patients (59%). The remaining 11 patients were treated conservatively (n = 3) or died during resuscitation (n = 8). Morbidity directly related to the liver injury was seen in 29 of 249 surviving patients (11%) although overall morbidity was 27% (67/249). Reoperation was required in 6% (14/249) with abscess or hematoma accounting for 11 of 14 operations. The overall mortality rate was 26% (86/335). Eighty two percent of patients (n = 276) had a grade I, II or III liver trauma according to Moore’s classification with a mortality of 12% (n = 32). The remaining 18% of patients (n = 59) had a grade IV or V liver trauma with a mortality of 44% (n = 26). Of the 86 deaths, head injury accounted for 48 (56% of deaths); liver hemorrhage for 17 (20%), liver sepsis for (1%) and other causes for 20 deaths (23%). Thus death due to the liver injury itself (hemorrhage and sepsis) occurred in 18 out of 335 patients (5% overall). Head injury accounted for the death of 48 out of 335 patients (14% overall). Over the past 13 years a trend has occurred at our institution whereby we are seeing less liver trauma in our population of multiply injured patients from 12% (1976–1983) down to 7% (1985–1989); with a gradual decline in overall mortality from 32% (1976–1983) to 19% (1985–1989), whereas the precentage of deaths due to head injuries and liver injury have increased.

The aim of this study was to investigate the efficiency of domestic physician-staffed helicopter emergency medical service (HEMS) for the transport of patients with severe trauma to a hospital. The study included patients with blunt trauma who were transported to our hospital by physician-staffed HEMS (Group P; n = 100) or nonphysician-staffed HEMS (Group NP; n = 80). Basic patient characteristics, transport time, treatment procedures, and medical treatment outcomes assessed using the Trauma and Injury Severity Score (TRISS) were compared between groups. We also assessed patients who were transported to the hospital within 3 h of injury in Groups P (Group P3; n = 50) and NP (Group NP3; n = 74). The severity of injury was higher, transport time was longer, and time from hospital arrival to operation room transfer was shorter for Group P than for Group NP (P < 0.001). Although Group P patients exhibited better medical treatment outcomes compared with Group NP, the difference was not statistically significant (P = 0.134 vs. 0.730). However, the difference in outcomes was statistically significant between Groups P3 and NP3 (P = 0.035 vs. 0.546). Under the current domestic trauma patient transport system in South Korea, physician-staffed HEMS are expected to increase the survival of patients with severe trauma. In particular, better treatment outcomes are expected if dedicated trauma resuscitation teams actively intervene in the medical treatment process from the transport stage and if patients are transported to a hospital to receive definitive care within 3 hours of injury.

Context: Ibuprofen is widely used to manage pain and inflammation after orthopaedic trauma, but its effect on acute swelling has not been investigated. Cathodal high-voltage pulsed current (CHVPC) at 120 pulses per second and 90% of visible motor threshold is known to curb edema formation after blunt trauma to the hind limbs of rats. Objective: To examine the effects of ibuprofen, continuous CHVPC, and simultaneous ibuprofen and CHVPC on acute edema formation after blunt trauma to the hind limbs of rats. Design: Randomized, parallel-group, repeated-measures design. Setting: Laboratory animal facility. Participants: A total of 21 3-month-old Zucker Lean rats (mass = 288 ± 55 g) were studied. Intervention(s): We assessed the effects of ibuprofen, continuous CHVPC, and simultaneous ibuprofen and CHVPC on acute edema formation after blunt trauma to the hind limbs of rats. Main Outcome Measure(s): Limb volumes were measured immediately before and after trauma and every 30 minutes over the 4 hours of the experiment. Results: Volumes of treated limbs of all 3 experimental groups were smaller (P < .05) than those of untreated limbs, but no treatment was more effective than another. Conclusions: Ibuprofen, CHVPC, and simultaneous ibuprofen and CHVPC effectively curbed edema after blunt injury by roughly 50% relative to untreated but similarly injured control limbs of rats.

Blunt prenatal trauma is known to have consequences to the developing brain, and can result in subdural hematoma (SDH) or epidural hematoma (EDH). The authors present a case of blunt prenatal trauma resulting in a fetal SDH, intraparenchymal hematoma, and intraventricular hemorrhage, and perform a systematic review of the literature. This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant studies (up to April 2016) that reported on cases of fetal SDH or EDH after blunt prenatal trauma were identified from the PubMed database. The primary outcome was fetal mortality, and the secondary outcome was neurological outcome. Fourteen studies were included in the analysis, comprising a total of 14 patients including the present case. The average gestational age at discovery of hemorrhage was 30.1 weeks. Nine mothers were in a motor vehicle collision and 3 were assaulted; the mechanism of injury for 2 mothers was not defined. Twelve patients had SDH, 1 had EDH, and 1 had conflicting reports. Three patients had intrauterine fetal demise, and 3 died in the neonatal period after birth. Three patients had persistent neurological deficit, and 5 were neurologically intact. Fetal SDH or EDH after blunt trauma to the mother trauma is rare and is associated with mortality. However, a significant number of patients can have good neurological outcomes.
Introduction The goal of non-operative management (NOM) for blunt splenic trauma (BST) is to preserve the spleen. The advantages of NOM for minor splenic trauma have been extensively reported, whereas its value for the more severe splenic injuries is still debated. The aim of this systematic review was to evaluate the available published evidence on NOM in patients with splenic trauma and to compare it with the operative management (OM) in terms of mortality, morbidity and duration of hospital stay. Methods For this systematic review we followed the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" statement. A systematic search was performed on PubMed for studies published from January 2000 to December 2011, without language restrictions, which compared NOM vs. OM for splenic trauma injuries and which at least 10 patients with BST. Results We identified 21 non randomized studies: 1 Clinical Controlled Trial and 20 retrospective cohort studies analyzing a total of 16,940 patients with BST. NOM represents the gold standard treatment for minor splenic trauma and is associated with decreased mortality in severe splenic trauma (4.78% vs. 13.5% in NOM and OM, respectively), according to the literature. Of note, in BST treated operatively, concurrent injuries accounted for the higher mortality. In addition, it was not possible to determine post-treatment morbidity in major splenic trauma. The definition of hemodynamic stability varied greatly in the literature depending on the surgeon and the trauma team, representing a further bias. Moreover, data on the remaining analyzed outcomes (hospital stay, number of blood transfusions, abdominal abscesses, overwhelming post-splenectomy infection) were not reported in all included studies or were not comparable, precluding the possibility to perform a meaningful cumulative analysis and comparison. Conclusions NOM of BST, preserving the spleen, is the treatment of choice for the American Association for the

INTRODUCTION The spleen remains one of the most frequently injured organs following blunt abdominal trauma. In 2012, regional trauma networks were launched across England and Wales with the aim of improving outcomes following trauma. This retrospective cohort study investigated the management and outcomes of blunt splenic injuries before and after the establishment of regional trauma networks. METHODS A dataset was drawn from the Trauma Audit Research Network database of all splenic injuries admitted to English and Welsh hospitals from 1 April 2010 to 31 March 2014. Demographic data, injury severity, treatment modalities and outcomes were collected. Management and outcomes were compared before and after the launch of regional trauma networks. RESULTS There were 1457 blunt splenic injuries: 575 between 2010 and 2012 and 882 in 2012-14. Following the introduction of the regional trauma networks, use of splenic artery embolotherapy increased from 3.5% to 7.6% (P = 0.001) and splenectomy rates decreased from 20% to 14.85% (P = 0.012). Significantly more patients with polytrauma and blunt splenic injury were treated with splenic embolotherapy following 2012 (61.2% vs. 30%, P < 0.0001). Increasing age, injury severity score, polytrauma and Charlson Comorbidity Index above 10 were predictors of increased mortality (P < 0.001). Increasing systolic blood pressure (odds ratio, OR, 0.757, 95% confidence interval, CI, 0.716-0.8) and Glasgow Coma Scale (OR 0.988, 95% CI 0.982-0.995) were protective. CONCLUSIONS This study demonstrates a reduction in splenectomy rate and an increased use of splenic artery embolotherapy since the introduction of the regional trauma networks. This may have resulted from improved access to specialist services and reduced practice variation since the establishment of these networks.

There are differing recommendations in the literature regarding cervical spine imaging in alert, asymptomatic geriatric patients. Previous studies also have not used computed tomography routinely. Given that cervical radiographs may miss up to 60 per cent of fractures, the incidence of cervical spine injuries in this population and its implications for clinical management are unclear. We conducted a retrospective study of blunt trauma patients 65 years and older who were alert, asymptomatic, hemodynamically stable, and had normal neurologic examinations. For inclusion, patients were required to have undergone computed tomography and plain radiographs. The presence and anatomic location of potentially distracting injuries or pain were recorded. Two hundred seventy-four patients were included, with a mean age of 76 +/- 10 years. The main mechanisms of injury were falls (51%) and motor vehicle crashes (41%). Nine of 274 (3%) patients had cervical spine injuries. The presence of potentially distracting injuries above the clavicles was associated with cervical injury when compared with patients with distracting injuries in other anatomic locations or no distracting injuries (8/115 vs 1/159, P = 0.03). There was no association of cervical spine injury with age greater or less than 75 years or with mechanism of injury. The overall incidence of cervical spine injury in the alert, asymptomatic geriatric population is low. The risk is increased with a potentially distracting injury above the clavicles. Patients with distracting injuries in other anatomic locations or no distracting injuries may not need routine cervical imaging.

A 39-year-old woman arrived at our emergency department, complaining of severe pain and swelling of her left leg. She had slipped down stairs and injured on her left leg about 3 months ago. Computed tomography angiography showed left distal superficial femoral artery’s pseudoaneurysm with arteriovenous fistula and thrombotic occlusion of left common iliac vein. We decided to do endovascular intervention due to severe venous hypertension and chronic inflammation around the fistula. The femoral arteriovenous fistula was closed via stent-graft (7 mm×5, 9 mm×5 cm) deployment. The occluded left iliac vein was reopened by nitinol metal stenting (12 mm×4 cm, 14 mm×4 cm). The authors report a very rare case of femoral arteriovenous fistula combined with iliac vein thrombosis developed after a blunt trauma. PMID:28377911

In the last few decades, various researches focus on the transient pressure in the behind armor blunt trauma. This paper presented a investigation on the transient pressure in the ballistic gelatin behind a soft body armor subjected to the impacting from three ammunitions. Experimental results show that three peaks appear on the pressure-time curves without taking into account the ammunition type and the impact velocity. Furthermore, numerical models of the test were created to compare modelling results to the pressure from the pressure gauges buried in the gelatin block. The main features on the pressure-time cure were discussed to analyze the wave formation and propagation. With the verified model, the effect of the boundary was also investigated to explain the wave reflection which appeared after two peaks.

In some fatalities from intense blunt trauma, the victims' clothes show strikingly yellow discoloration being in topographic correspondence with lacerated skin and crush damage to the underlying fatty tissue. This phenomenon is especially pronounced in light-colored textiles such as underwear made of cotton and in the absence of concomitant blood-staining. The constellation of findings seems to indicate that the fabric has been soaked with liquid body fat deriving from the contused adipose tissue. To check this hypothesis, textiles suspected to be contaminated with fat were investigated in 6 relevant cases. GC-MS-analysis proved the presence of 11 fatty acids. The fatty acid composition was similar to that of human adipose tissue with a high proportion of oleic acid (18:1). In total, the morphological and chemical findings demonstrated that the yellow discoloration of the victims' clothes was caused by fat from traumatized adipose tissue.

Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea. PMID:22880189

Extracranial vertebral pseudoaneurysms that develop following blunt trauma to the cervical area may have a benign course; however, embolic or ischemic stroke and progressive pseudoaneurysm enlargement may occur. We review the presentation and endovascular management of pseudoaneurysms of the cervical vertebral artery (VA) due to blunt trauma in nine patients (eight male, mean age 27years). Pseudoaneurysms occurred in dominant vessels in seven patients and coexisted with segmental narrowing in six. We favored endovascular intervention during the acute phase only in cases with significant narrowing of a dominant VA, especially when anticoagulation was contraindicated. Four patients were treated during the acute stage (contraindication to anticoagulation, mass effect, severely injured dominant VA/impending stroke); five during the chronic phase (pseudoaneurysm growth, ischemic stroke on aspirin prophylaxis, patient preference). Reconstructive techniques were favored over deliberate endovascular occlusion when dominant vessels were involved. Arterial reconstruction was performed in eight of nine patients using a flow-diverter implant (5 patients), stent-assisted coiling (1), overlapping stent implant (1), or implantation of a balloon-expandable stent (1). Deliberate VA occlusion with coils was performed in one of nine patients due to suboptimal expansion of the stented artery after flow-diverter implant. No neurological complications occurred during follow-up. All cases treated by reconstructive techniques showed complete, persistent pseudoaneurysm occlusion and full arterial patency. Endovascular therapy of traumatic VA pseudoaneurysms using neurostents and flow-diverters resulted in occlusion of the pseudoaneurysms, preservation of the parent vessel, and no periprocedural or delayed clinical complications, supporting the feasibility and safety of the approach.

Radial head fractures are common injuries, occurring in about 20% of all acute elbow injuries. Isolated radial head fractures are not common and include about 2% of all fractures around the elbow. Bilateral radial head fractures are rare and usually associated with severe trauma and associated fractures and dislocations. We report a case of bilateral undisplaced radial head fracture in a woman, following a simple fall. Early recognition, proper management, and physical therapy led to complete recovery and full functional movement of the elbow. PMID:16369234

Introduction Cost and radiation risk have prompted intense examination of trauma patient imaging. A proposed decision instrument (DI) for the use of chest computed tomography (CT), (CCT) in blunt trauma patients includes thoracic spine (TS) tenderness, altered mental status (AMS) and distracting painful injury (DPI) as potential predictor variables. TS CT is a separate, costly study whose value is currently ill-defined. The objective of this study is to determine test characteristics of these predictor variables alone, and in combination, to derive a TS injury DI. Methods Prospective cohort study of blunt trauma patients age > 14 in a Level I Trauma Center who had either CCT or TS CT. Results Of 1,798 blunt trauma patients, 1,174 (65.3%) had CCT, and 46 (2.6%) had a TS CT at physician discretion. CCT identified 58 TS injuries in 1,220 patients (4.8%). For 1,032 patients without AMS, 18/35 had TS tenderness, for sensitivity of 51.4%, specificity 84.7%, positive (PPV) and negative predictive values (NPV) of 10.5% and 98.0%. Positive likelihood ratio (+LR) was 3.35, with negative (−LR) 0.57. Among the 58 TS injuries, 23 had AMS for sensitivity of 39.7%, with other test characteristics of 85.8%, 12.2%, 96.6%, with +LR 2.79 and −LR 0.70. Thirty-eight of 58 had DPI, for sensitivity 65.5%, with other test characteristics 65.7%, 8.7%, and 97.4%, with +LR 1.91 and −LR 0.52. Combining 3 predictor variables into a proposed DI found 56/58 injuries for test characteristics of 96.6% (95% CI 88.1–99.6%), 49.1% (46.1–52.0%), 8.6% (6.6–11.1%) and 99.7% (CI 98.7–100%), with +LR 1.90 (1.76–2.04) and −LR 0.07 (0.02–0.28). If validated, the DI would exclude 572/1,220 CCT patients from separate TS CT (46.9%, CI 44.1–49.7%), and 141/511 (27.6%, CI 23.8–31.7%) patients who actually had TS CT in our cohort. Medicare payment at our center for sagittal reconstructions of TS CT is $280 for professional plus technical charges ($3,312 per study). The DI, if validated

Blunt trauma to chest cause injury to various cardiac structures. Isolated rupture of aortic valve without aortic dissection is rare complication of blunt chest trauma and can be caused by a tear or avulsion of the valve. We report a case of a 35-year-old male who presented with severe aortic insufficiency due to rupture of a non-infected congenital bicuspid aortic valve following non-penetrating chest trauma. The diagnosis was suggested by echocardiography and was confirmed by intra-operative and histological findings. The patient was successfully treated with surgical valve replacement with uneventful postoperative course and recovery. We describe patho-physiology, clinical manifestations, management and the literature review of traumatic rupture of bicuspid aortic valve. PMID:28164016

Few studies have focused on a description of the fracture toughness properties of dentin in terms of resistance-curve (R-curve) behavior, i.e., fracture resistance increasing with crack extension, particularly in light of the relevant toughening mechanisms involved. Accordingly, in the present study, fracture mechanics based experiments were conducted on elephant dentin in order to determine such R-curves, to identify the salient toughening mechanisms and to discern how hydration may affect their potency. Crack bridging by uncracked ligaments, observed directly by microscopy and X-ray tomography, was identified as a major toughening mechanism, with further experimental evidence provided by compliance-based experiments. In addition, with hydration, dentin was observed to display significant crack blunting leading to a higher overall fracture resistance than in the dehydrated material. The results of this work are deemed to be of importance from the perspective of modeling the fracture behavior of dentin and in predicting its failure in vivo.

A 19-year-old male suffered orthopedic fractures, blunt solid organ injury and pneumopericardium after a fall from 40 feet. With the exception of an external fixation device, he was managed non-operatively and discharged to a rehabilitation unit after 8 days. He was readmitted 4 days later with chest pain and clinical evidence of pericardititis that resolved with the initiation of non-steroidal anti-inflammatory drugs and colchicine. He returned to the rehabilitation hospital, but was readmitted once again for chest pain and hypotension. Echocardiogram revealed cardiac tamponade that required emergent drainage. He tolerated the procedure well and was discharged home from the hospital to continue treatment for his pericarditis. He is doing well at 3 months of follow-up. PMID:25709254

Full medical evaluation is paramount for all trauma patients. Minor traumas are often overlooked, as they are thought to bear low injury potential. In this case report, we describe the case of a 48-year-old man presenting to our Emergency Department with mild to moderate right-sided shoulder and scapular pain following a fall from his own height ten days previously. Clinical and paraclinical investigations (CT) revealed diffuse right shoulder pain, with crepitations on palpation of the neck, right shoulder, and right lateral chest wall. Computed tomography (CT) demonstrated right-sided costal fractures (ribs 7 to 9), with diffuse subcutaneous emphysema and pneumomediastinum due to laceration of the visceral and parietal pleura and the adjacent lung parenchyma. In addition, a small ipsilateral pneumothorax was found. Surprisingly, the clinical status was only minimally affected by mild to moderate pain and minor functional impairment. PMID:28392950

Cardiac contusion is usually caused by blunt chest trauma and, although it is potentially a life-threatening condition, the diagnosis of a myocardial contusion is difficult because of non-specific symptoms and the lack of an ideal test to detect myocardial damage. Cardiac enzymes, such as creatine kinase (CK), creatine kinase MB fraction (CK-MB), cardiac troponin I (cTn-I), and cardiac troponin T (cTn-T) were used in previous studies to demonstrate the blunt cardiac contusion (BCC). Each of these diagnostic tests alone is not effective for diagnosis of BCC. The aim of this study was to investigate the serum heart-type fatty acid binding protein (h-FABP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), CK, CK-MB, and cTn-I levels as a marker of BCC in blunt chest trauma in rats. The eighteen Wistar albino rats were randomly allocated to two groups; group I (control) (n=8) and group II (blunt chest trauma) (n=10). Isolated BCC was induced by the method described by Raghavendran et al. (2005). All rats were observed in their cages and blood samples were collected after five hours of trauma for the analysis of serum h-FABP, NT-pro BNP, CK, CK-MB, and cTn-I levels. The mean serum NT-pro BNP was significantly different between group I and II (10.3 ± 2.10 ng/L versus 15.4 ± 3.68 ng/L, respectively; P=0.0001). NT-pro BNP level >13 ng/ml had a sensitivity of 87.5%, a specificity of 70%, a positive predictive value of 70%, and a negative predictive value of 87.5% for predicting blunt chest trauma (area under curve was 0.794 and P=0.037). There was no significant difference between two groups in serum h-FABP, CK, CK-MB and c Tn-I levels. A relation between NT-Pro BNP and BCC was shown in this study. Serum NT-proBNP levels significantly increased with BCC after 5 hours of the blunt chest trauma. The use of NT-proBNP as an adjunct to other diagnostic tests, such as troponins, electrocardiography (ECG), chest x-ray and echocardiogram may be beneficial for diagnosis of

Introduction: Reduction of nonessential angiogram and embolization for patients sustaining blunt abdominal and pelvic trauma would allow improved utilization and decreased morbidity related to nontherapeutic embolization. We hypothesized that the nature of intravenous contrast extravasation (IVCE) on computed tomography (CT) would be directly related to the finding of extravasation on angiogram and need for embolization. Methods: A 5-year retrospective evaluation of trauma patients with IVCE on CT. Demographics, hemodynamics, and IVCE location and maximal dimension/volume were examined for relationship to IVCE on angiography and need for embolization. Primary complications were defined as nephropathy and acute respiratory distress syndrome. Results: A total of 128 patients were identified with IVCE on CT. Ninety-seven (75.8%) also had IVCE identified on angiography requiring some form of embolization. The size of IVCE on CT was not related to IVCE on angiogram (P = 0.69). Location of IVCE was related to need for embolization, with spleen embolization (85.4%) being much more frequent than liver (51.5%, P = 0.006). Complication rate was 8.7% in all patients, and was not different between patients undergoing embolization and those who did not (P = 0.40). Conclusion: IVCE volume was not predictive of continued bleeding and need for embolization. However, splenic injuries with IVCE required embolization more frequently. In contrast, liver injuries were found to have infrequent on-going IVCE on angiography. Complications associated with angiogram with or without embolization are infrequent, and CT findings may not be predictive of ongoing bleeding. We do not recommend selective exclusion of patients from angiographic evaluation when a blush is present.

Summary Background Diaphragmatic injuries occur in 0.8–8% of patients with blunt trauma. The clinical diagnosis of diaphragmatic rupture is difficult and may be overshadowed by associated injuries. Diaphragmatic rupture does not resolve spontaneously and may cause life-threatening complications. The aim of this study was to present radiological findings in patients with diaphragmatic injury. Material/Methods The analysis of computed tomography examinations performed between 2007 and 2012 revealed 200 patients after blunt thoraco-abdominal trauma. Diaphragmatic rupture was diagnosed in 13 patients. Twelve of these patients had suffered traumatic injuries and underwent a surgical procedure that confirmed the rupture of the diaphragm. Most of diaphragmatic ruptures were left-sided (10) while only 2 of them were right-sided. In addition to those 12 patients there, another patient was admitted to the emergency department with left-sided abdominal and chest pain. That patient had undergone a blunt thoracoabdominal trauma 5 years earlier and complained of recurring pain. During surgery there was only partial relaxation of the diaphragm, without rupture. The most important signs of the diaphragmatic rupture in computed tomography include: segmental discontinuity of the diaphragm with herniation through the rupture, dependent viscera sign, collar sign and other signs (sinus cut-off sign, hump sign, band sign). Results In our study blunt diaphragmatic rupture occurred in 6% of cases as confirmed intraoperatively. In all patients, coronal and sagittal reformatted images showed herniation through the diaphragmatic rupture. In left-sided ruptures, herniation was accompanied by segmental discontinuity of the diaphragm and collar sign. In right-sided ruptures, predominance of hump sign and band sign was observed. Other signs were less common. Conclusions The knowledge of the CT findings suggesting diaphragmatic rupture improves the detection of injuries in thoraco

Blunt thoraco-abdominal trauma in collision injuries in road traffic accident (RTA) occasionally results in diaphragmatic injury and rupture besides other serious multisystem injuries. These diaphragmatic injuries (DI) frequently go undetected specially when occur on the right side. DI associated with hemothorax need insertion of intercostal tube drainage (ICTD). ICTD has never been reported to precipitate diaphragmatic rupture and hernia. We are reporting such a rare case for the first time in medical literature. PMID:26933316

This study evaluates the efficacy of arterial embolization (AE) for blunt hepatic traumas (BHT) as part of a combined management strategy based on the hemodynamic status of patients and CT findings. From 2000 to 2005, 84 patients were admitted to our hospital for BHT. Of these, 14 patients who had high-grade injuries (grade III [n = 2], grade IV [n = 9], grade V [n = 3]) underwent AE because of arterial bleeding and were included in the study. They were classified into three groups according to their hemodynamic status: (1) unresponsive shock, (2) shock improved with resuscitation, and (3) hemodynamic stability. Four patients (group 1) underwent, first, laparotomy with packing and, then, AE for persistent bleeding. Ten patients who were hemodynamically stable (group 1) or even unstable (group 2) underwent AE first, based on CT findings. AE was successful in all cases. The mortality rate was 7% (1/14). Only two angiography-related complications (gallbladder infarction) were reported. Liver-related complications (abdominal compartment syndrome and biliary complications) were frequent and often required secondary interventions. Our multidisciplinary approach for the management of BHT gives a main role to embolization, even for hemodynamically unstable patients. In this strategy AE is very efficient and has a low complication rate.

Euthanasia of small numbers of birds in case of injury or other illness directly on the farm may be necessary for welfare reasons. This should be done without transportation of the moribund animals in order to minimize pain and distress. Blood loss has to be avoided to minimize the risk of contaminating the environment. Cervical dislocation in combination with a blunt trauma may be an appropriate way to achieve this aim but the bird's age and body weight may influence the practicability of this method in the field. In this study, we evaluated broilers, broiler breeders, and turkeys of different age groups and weights up to nearly 16 kg for the efficacy of blunt trauma to induce unconsciousness, allowing subsequent killing of the bird without pain. The effect of blunt trauma on the brain was determined by electroencephalography (EEG). Auditory evoked potentials (AEPs) were recorded for each animal. Convulsions or tonic seizures were observed in all investigated animals after blunt trauma, including strong wing movements, torticollis, and stretching of legs. The EEG results demonstrate that the blunt trauma induced by a single, sufficiently strong hit placed in the frontoparietal region of the head led to a reduction or loss of the AEP in all groups of birds. These results clearly indicate a loss of sensibility and induction of unconsciousness, which would allow painless killing of the birds immediately after the induction of the blunt trauma.

Abstract Effective analgesia in the early stages after any major traumatic event remains pivotal to optimal trauma management. For patients with significant thoracic injuries, this is paramount to ensure ongoing efficient respiratory function. The aim of this study was to investigate the use of analgesic modes in the management of patients with a primary thoracic injury and blunt mechanism of injury. By understanding variables that influence the use of varying analgesic modes and influence the development of pulmonary complications, there should be more uniform evidence-based prescription in the future. This retrospective study considered analgesic use in patients admitted after blunt thoracic injuries at one major trauma center over a 2-year period. Pulmonary complications measured included both infective and ventilator-associated failure. Univariate and multivariate analyses were used to identify patient and injury severity characteristics and their association with respiratory complications. A total of 401 cases were reviewed and analyzed: 159 received Patient Controlled Analgesia (PCA), 32 received PCA and epidural analgesia (EA), 6 received EA alone, and 204 received interval-administered analgesia. There were no significant differences in the rates of complication when compared between analgesic modes. Patients who developed pneumonia had significantly increased number of thoracic fractures and underlying organ injury (P < 0.05). Logistic regression analysis highlighted duration of intercostal drain insertion (OR 1.377, P = 0.001) and premorbid cardiac disease (OR 2.624, P = 0.042) and ICU length of stay (OR: 1.146, P < 0.001) as significant predictors of developing pneumonia in this patient group. Examining the different analgesic modes, this study failed to identify a particular analgesic mode that was more effective in preventing pulmonary complications in blunt thoracic injuries. However, variables that may influence usage of different

Purpose Using the data delivered by the German Trauma Register DGU® from 2002 till 2013, the value of different therapies of blunt thoracic aortic injury (BTAI) in Germany was analyzed. Methods Prospectively collected data of patients suffering from BTAI were retrospectively analyzed with focus on the different treatment modalities for grade I–IV injuries. Results 821 patients suffering from BTAI were identified: 51.6% (424) grade I injury, 35.4% (291) grade II or III injury and 12.9% (106) grade IV injury (77.5% men [44.94 ± 20.6 years]). The main patterns of injury were high- speed accidents and falls (78.0% [n = 640], 21.8% [n = 171] respectively). Significant differences between grade I and grade II/III as well as IV injuries could be assessed for the incidence of cardiopulmonary resuscitation, a Glasgow Coma Scale score below 8 and a systolic blood pressure below 90 mmHg (p-value: <0.001). In the primary admission subgroup, 44.1% (197/447) of the patients received best medical treatment, 55.9% received surgical intervention (250/447): Thereof 37.2% (93/250) received open surgery and 62.8% (147/250) had been treated by endovascular means. Significantly lower 24-h- and in-hospital-mortality rates were encountered after endovascular treatment for all gradings of BTAI (p-value: <0.001). Yet this subgroup of patients showed the lowest incidence of further severe injuries and cardiac arrest. Conclusion Endovascular therapy became the treatment of choice for BTAI in Germany. Patients who have been treated by surgical means showed the highest survival rate, especially endovascular therapy showed a favorable low mortality rate. PMID:28346475

Positron emission tomography with [(18)F]-fluorodeoxyglucose provides functional and anatomic information by visualising the uptake of radiolabelled glucose in tumour and inflammatory cells. We report delayed diagnosis of necrosis of the gastric fundus after blunt abdominal trauma in a 73-year-old man. After a car accident with head-on collision, the patient was stabilised in our emergency room. His femur was treated by internal fixation, his ellbow was stabilised by a fixateur externe. During surgery his status deteriorated. The patient was in need of high dosage of inotrops during the following days. He had a biventricular pacemaker implanted because of ischemic myocardiopathy, and he suffered from renal insufficiency. Over the next days, his haemodynamics improved. A central venous line had to be removed because of ensuing septic fever. The patient complained of upper abdominal pain and nausea. A sonography and computer tomography without contrast medium were performed with negative result. Because of contamination of the central venous line with Staphylococcus epidermidis the pacemaker was evaluated for infection by transoesophageal echocardiography, again without any findings. Because of ongoing fever and positive inflammatory markers a positron emission tomography was indicated, as a contrast examination and a magnetic resonance examination were not feasible because of the renal insufficiency and the pacemaker, respectively. Prophylactic removal of the pacemaker would have been a substantial risk for the patient due to his underlying myocardiopathy. Positron emission tomography showed an increased tracer uptake in the gastric fundus, which turned out to be necrotic by endoscopy. A laparoscopic resection followed, and drainage of an abscess, which had evolved subsequently between stomach and spleen stopped the inflammatory process. This case report demonstrates that positron emission tomography may be an alternative to computer tomography with contrast medium

Introduction Splenic pseudoaneurysms (SPA) are a rare but serious sequela of blunt traumatic injury to the spleen. Management of adult blunt splenic trauma is well-studied, however, in children, the management is much less well-defined. Presentation of case A 15 year-old male presented with severe abdominal pain of acute onset after sustaining injury to his left side while playing football. FAST was positive for free fluid in the abdomen. Initial abdomen CT demonstrated a grade III/IV left splenic laceration with moderate to large hemoperitoneum with no active extravasation or injury to the splenic vessels noted. A follow-up CT angiography of the abdomen demonstrated a splenic hypervascular structure suspicious for a small pseudoaneurysm. Splenic arteriogram which demonstrated multiple pseudoaneurysms arising from the second order splenic artery branches which was angioembolized and treated. Discussion & conclusion Questions still remain regarding the timing of repeat imaging for diagnosis of SPA following non-operative blunt splenic trauma, which patients should be imaged, and how to manage SPA upon diagnosis. More clinical study and basic science research is warranted to study the disease process of SPA in pediatric patient. We believe that our proposed management algorithm timely detect formation of delayed SPA formation and addresses the possible fatal disease course of pediatric SPA. PMID:26117449

Aneurysmal bone cysts predominantly occur in young adults and the long bones, the lumbar spine and the pelvis are mainly affected. This article presents the case of a 22-year-old woman with the very rare localization of an aneurysmal bone cyst of the atlas and an atlas fracture after a minor trauma. The initial radiological diagnosis was a suspicted aneurysmal bone cyst which was confirmed histologically. Due to the unstable fracture it was decided to carry out surgical treatment with occipitocervical stabilization in combination with a transoral bone graft. After a period of 11 months the fracture had completely healed and the implants were removed without any complications.

Aortic regurgitation resulting from blunt chest trauma has been reported only 95 times, to our knowledge. The noncoronary and right coronary cusps are the cardiac structures most often injured. Although the aortic leaflets can appear to be undamaged after nonpenetrating trauma, they can have pathologic abnormalities and insufficient function. Some cases of posttraumatic aortic regurgitation progress slowly. Aortic valve replacement is the optimal treatment. We present the case of a then-62-year-old man who has lived more than 5 years after blunt-trauma aortic regurgitation. His is the only case of long-term survival on medical therapy alone among the 96 cases summarized in this report. PMID:27777534

Introduction Scapular fractures are generally occur from in high-energy traumas and are associated with a high incidence of morbidity and mortality. Presentation of case We present an unusual scapular fracture that occurred with a rare mechanism. A 23-year-old male patient who led an active sports life for 10 years and played ice hockey for the last 5 years. In a competition, he felt a sudden pain in his right scapula after hit the puck. He did not experience any direct trauma to his shoulder and there was no evidence of any pathological fracture. The fracture was isolated in the scapular body and it was classified as type 4, according to Hardegger classification. The was patient immobilized with a Velpau bandage for three weeks and then treated with physiotherapy for shoulder rehabilitation. Discussion The fracture mechanism was likely a disharmonius contracture of the agonist and antagonist muscles of the shoulder joint while hitting the puck. Conclusion Scapular fractures are generally seen along with other injuries, but in this case we wanted to emphasize that care has to been taken to diagnose an isolated scapular fracture while assessing shoulder pain.

Blunt trauma resulting in rib fractures can be associated with hemothorax, pneumothorax, pulmonary contusions or less frequently chest and abdominal wall hematomas. Our case describes the first report of hemoperitoneum secondary to intercostal arterial bleeding from blunt trauma in a patient on anticoagulation. PMID:28108633
Background High mobility group box 1 (HMGB1) is a late mediator of systemic inflammation. Extracellular HMGB1 play a central pathogenic role in critical illness. The purpose of the study was to investigate the association between plasma HMGB1 concentrations and the risk of poor outcomes in patients with severe blunt chest trauma. Methods The plasma concentrations of HMGB1 in patients with severe blunt chest trauma (AIS ≥ 3) were measured by a quantitative enzyme-linked immunosorbent assay at four time points during seven days after admission, and the dynamic release patterns were monitored. The biomarker levels were compared between patients with sepsis and non-sepsis, and between patients with multiple organ dysfunction syndrome (MODS) and non-MODS. The related factors of prognosis were analyzed by using multivariate logistic regression analysis. The short-form 36 was used to evaluate the quality of life of patients at 12 months after injury. Results Plasma HMGB1 levels were significantly higher both in sepsis and MODS group on post-trauma day 3, 5, and 7 compared with the non-sepsis and non-MODS groups, respectively. Multivariate analysis showed that HMGB1 levels and ISS were independent risk factors for sepsis and MODS in patients with severe blunt chest trauma. Conclusions Plasma HMGB1 levels were significantly elevated in patients with severe blunt chest trauma. HMGB1 levels were associated with the risk of poor outcome in patients with severe blunt chest trauma. Daily HMGB1 levels measurements is a potential useful tool in the early identification of post-trauma complications. Further studies are needed to determine whether HMGB1 intervention could prevent the development of sepsis and MODS in patients with severe blunt chest trauma. PMID:25085006
Introduction The benefits of transporting severely injured patients by helicopter remain controversial. This study aimed to analyze the impact on mortality of helicopter compared to ground transport directly from the scene to a University hospital trauma center. Methods The French Intensive Care Research for Severe Trauma cohort study enrolled 2,703 patients with severe blunt trauma requiring admission to University hospital intensive care units within 72 hours. Pre-hospital and hospital clinical data, including the mode of transport, (helicopter (HMICU) versus ground (GMICU), both with medical teams), were recorded. The analysis was restricted to patients admitted directly from the scene to a University hospital trauma center. The main endpoint was mortality until ICU discharge. Results Of the 1,958 patients analyzed, 74% were transported by GMICU, 26% by HMICU. Median injury severity score (ISS) was 26 (interquartile range (IQR) 19 to 34) for HMICU patients and 25 (IQR 18 to 34) for GMICU patients. Compared to GMICU, HMICU patients had a higher median time frame before hospital admission and were more intensively treated in the pre-hospital phase. Crude mortality until hospital discharge was the same regardless of pre-hospital mode of transport. After adjustment for initial status, the risk of death was significantly lower (odds ratio (OR): 0.68, 95% confidence interval (CI) 0.47 to 0.98, P = 0.035) for HMICU compared with GMICU. This result did not change after further adjustment for ISS and overall surgical procedures. Conclusions This study suggests a beneficial impact of helicopter transport on mortality in severe blunt trauma. Whether this association could be due to better management in the pre-hospital phase needs to be more thoroughly assessed. PMID:23131068

Pseudoaneurysm and arteriovenous fistulae of the renal artery are rare complications of kidney trauma. They commonly result from open traumas and occur within days after the injury. Common symptoms include acute haematuria, pain, or hypertension. We report the case of a fifty-three-year-old man presenting with symptomatic complex chronic high flow kidney arteriovenous fistula with interposition of a pseudoaneurysmal pouch and arterial aneurysmal dilatation in a solitary left kidney 38 years after a blunt trauma. Those conditions were successfully treated by endovascular embolization followed by regular radiologic, biological, and clinical follow-up. To the best of our knowledge, few similar cases were reported more than 20 years after trauma. However, no case combining an arteriovenous fistula and a pseudoaneurysm revealing as late as 38 years after trauma was found. In addition, management of those conditions on a solitary kidney and outcomes has not been described. We believe that our case depicts the clinical presentation and management of this rare entity that should not be unrecognized due to its potential lethal implications. PMID:28386510

Few studies have examined the relationship between more-than-minimal-trauma fractures and bone density. This study demonstrated that more-than-minimal-trauma fractures are associated with lower bone density similar to that seen in minimal trauma fractures. Men and women over 50 years with a more-than-minimal-trauma fracture should be investigated to exclude low bone density.

This study aims to investigate the risk of subsequent fractures after low-trauma fracture in frail older people. A total of 1412 elderly residents (mean age 86.2 years, SD 7.0 years, female 77%) were recruited from aged care facilities in Australia. Residents were assessed and then followed for any fracture for 2 years and hip fractures for at least 5 years. Residents with and without a newly acquired fracture in the first 2 years were compared for risk of subsequent hip fracture. Residents with a nonhip fracture in the first 2 years had an increased risk of subsequent hip fracture for about 2.5 years, whereas those with a hip fracture had a similar risk over the whole period compared with those with no fracture. During these 2.5 years, 60, 28, and 6 subsequent hip fractures occurred in the nonfracture group (n = 953), the nonhip fracture group (n = 194), and the hip fracture group (n = 101), respectively, resulting in the probability of subsequent hip fracture of 8.0%, 19.9%, and 10.4%, respectively. Compared with the nonfracture group, the hazard ratio (HR) was 2.82 [95% confidence interval (CI) 1.73-4.59; p < .001] for the nonhip fracture group and 1.48 (95% CI 0.63-3.49, p = .37) for the hip fracture group after adjusting for age, sex, residence type, calcaneal broadband ultrasound attenuation, fracture history, weight, lower leg length, immobility, cognitive function, and medications. Frail institutionalized older people with newly acquired fractures are at increased risk of subsequent hip fracture for the next few years. Accordingly, despite their advanced age, they are a high-priority target group to investigate interventions that might reduce the risk of hip fracture.

Necrotizing fasciitis (NF) is a rare bacterial infection with dramatic course, characterized by widespread necrosis of the skin, subcutaneous tissue, and superficial fascia which can often lead to death. We present a case of a 27-year-old male with NF. One day after experiencing blunt abdominal trauma caused by falling over bike handlebars, the patient was admitted to a regional hospital and treated for diffuse abdominal pain and large hematoma of the anterior abdominal wall. Due to worsening of general condition, he was referred to our hospital the following day and operated on urgently. Surgery revealed rupture of the coecum with peritonitis and abdominal wall infection. After surgery, fulminant necrotizing fasciitis developed. Antibiotics were prescribed according to wound cultures and subsequent necrectomies were performed. After 25 days, reconstruction of the abdominal wall with skin grafts was obtained. Despite all resuscitation measures including fluids, blood transfusions, and parenteral nutrition, lung infection and MODS caused death 42 days after initial operation. Blunt abdominal trauma can cause the rupture of intestine, and if early signs of peritoneal irritation should present, emergency laparotomy should be performed. Disastrous complication are rare but lethal.

A 12-year-old boy suffered a blunt chest trauma. Some hours later, a pulsatile bilateral jugular venous distension, a holosystolic murmur heard at the low parasternal border and hepatomegaly were observed. On echocardiography, ruptured chordae tendineae of the posterior leaflet of the tricuspid valve, as well as tricuspid regurgitation were detected. He remained asymptomatic during hospital stay and was discharged home in good condition. Thus, isolated ruptured chordae tendineae of the posterior leaflet of the tricuspid valve is another cause of tricuspid regurgitation following blunt chest trauma.

BACKGROUND With the use of the framework advocated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group, our aims were to perform a systematic review and to develop evidence-based recommendations that may be used to answer the following PICO [Population, Intervention, Comparator, Outcomes] question: In the obtunded adult blunt trauma patient, should cervical collar removal be performed after a negative high-quality cervical spine (C-spine) computed tomography (CT) result alone or after a negative high-quality C-spine CT result combined with adjunct imaging, to reduce peri-clearance events, such as new neurologic change, unstable C-spine injury, stable C-spine injury, need for post-clearance imaging, false-negative CT imaging result on re-review, pressure ulcers, and time to cervical collar clearance? METHODS Our protocol was registered with the PROSPERO international prospective register of systematic reviews on August 23, 2013 (Registration Number: CRD42013005461). Eligibility criteria consisted of adult blunt trauma patients 16 years or older, who underwent C-spine CT with axial thickness of less than 3 mm and who were obtunded using any definition. Quantitative synthesis via meta-analysis was not possible because of pre-post, partial-cohort, quasi-experimental study design limitations and the consequential incomplete diagnostic accuracy data. RESULTS Of five articles with a total follow-up of 1,017 included subjects, none reported new neurologic changes (paraplegia or quadriplegia) after cervical collar removal. There is a worst-case 9% (161 of 1,718 subjects in 11 studies) cumulative literature incidence of stable injuries and a 91% negative predictive value of no injury, after coupling a negative high-quality C-spine CT result with 1.5-T magnetic resonance imaging, upright x-rays, flexion-extension CT, and/or clinical follow-up. Similarly, there is a best-case 0% (0 of 1,718 subjects in 11 studies) cumulative

A 59-year-old man suffered blunt injury to the left chest during a fall in August 2004. He had 5 repeated episodes of back and left chest pain in three years since August 2005. Since these symptoms were accompanied by left pleural effusion and serum inflammatory reaction, the tentative diagnosis was pleuritis. Although examinations of pleural effusion showed exudation with marked augmentation of inflammatory cells, there were no findings that suggested the cause of repetitive pleuritis. All symptoms were relieved within one or two weeks following administration of non-steroid anti-inflammatory drugs. Surgical thoracoscopy was carried out to investigate the cause of repeated pleuritis, and an acquired deficit of the left pericardium was noted. We considered this case to be postcardiac injury syndrome causing repeated pleuritis following blunt chest injury.

This case report describes a right subclavian artery aneurysm secondary to long-term repetitive blunt trauma. A 62-year-old man with a right subclavian artery aneurysm had had a history of bird hunting using a shotgun that impacted substantially against his right clavicula and shoulder weekly for >20 years. The patient underwent open repair with partial sternotomy and distal balloon control. The aneurysmal sac was resected, and the right subclavian artery was reconstructed with a primary end-to-end anastomosis. Histopathologic examination of the resected aneurysmal wall revealed that all three layers of the arterial wall were comparatively intact, with fibrosis and lipid deposition in the intima and in various degrees of degeneration in the media, suggesting a true aneurysm.

Patients with a (potential) cervical spine injury can be subdivided into low-risk and high-risk patients. With a detailed history and physical examination the cervical spine of patients in the "low-risk" group can be "cleared" without further radiographic examinations. X-ray imaging (3-view series) is currently the primary choice of imaging for patients in the "low-risk" group with a suspected cervical spine injury after blunt trauma. For patients in the "high-risk"group because of its higher sensitivity a computed tomography scan is primarily advised or, alternatively, the cervical spine is immobilised until the patient can be reliably questioned and examined again. For the imaging of traumatic soft tissue injuries of the cervical spine magnetic resonance imaging is the technique of choice.

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game. An initial computerized tomography (CT) scan of the brain was normal; a CT angiogram (CTA) of the neck and carotids did not reveal obstruction, dissection, stenosis, or abnormalities of the carotid or vertebral vessels and the patient was subsequently discharged. A magnetic resonance imaging (MRI) of the brain obtained four days after the initial injury demonstrated an acute infarct in the right middle cerebral artery (MCA) territory. Thus, despite initial negative imaging, neurological deficits must be aggressively pursued in order to prevent stroke in BCVI cases.

Cigarette smoking (CS) aggravates post-traumatic acute lung injury and increases ventilator-induced lung injury due to more severe tissue inflammation and apoptosis. Hyper-inflammation after chest trauma is due to the physical damage, the drop in alveolar PO2, and the consecutive hypoxemia and tissue hypoxia. Therefore, we tested the hypotheses that 1) CS exposure prior to blunt chest trauma causes more severe post-traumatic inflammation and thereby aggravates lung injury, and that 2) hyperoxia may attenuate this effect. Immediately after blast wave-induced blunt chest trauma, mice (n=32) with or without 3-4 weeks of CS exposure underwent 4 hours of pressure-controlled, thoraco-pulmonary compliance-titrated, lung-protective mechanical ventilation with air or 100 % O2. Hemodynamics, lung mechanics, gas exchange, and acid-base status were measured together with blood and tissue cytokine and chemokine concentrations, heme oxygenase-1 (HO-1), activated caspase-3, and hypoxia-inducible factor 1-α (HIF-1α) expression, nuclear factor-κB (NF-κB) activation, nitrotyrosine formation, purinergic receptor 2X4 (P2XR4) and 2X7 (P2XR7) expression, and histological scoring. CS exposure prior to chest trauma lead to higher pulmonary compliance and lower PaO2 and Horovitz-index, associated with increased tissue IL-18 and blood MCP-1 concentrations, a 2-4-fold higher inflammatory cell infiltration, and more pronounced alveolar membrane thickening. This effect coincided with increased activated caspase-3, nitrotyrosine, P2XR4, and P2XR7 expression, NF-κB activation, and reduced HIF-1α expression. Hyperoxia did not further affect lung mechanics, gas exchange, pulmonary and systemic cytokine and chemokine concentrations, or histological scoring, except for some patchy alveolar edema in CS exposed mice. However, hyperoxia attenuated tissue HIF-1α, nitrotyrosine, P2XR7, and P2XR4 expression, while it increased HO-1 formation in CS exposed mice. Overall, CS exposure aggravated post

Cerebral venous air embolism is sometimes caused by head trauma. One of the paths of air entry is considered a skull fracture. We report a case of cerebral venous air embolism following head trauma. The patient was a 55-year-old man who fell and hit his head. A head computed tomography (CT) scan showed the air in the superior sagittal sinus; however, no skull fractures were detected. Follow-up CT revealed a fracture line in the right temporal bone. Cerebral venous air embolism following head trauma might have occult skull fractures even if CT could not show the skull fractures.

DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assesss the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or interstitial changes in patients with blunt chest trauma. A total of 26 patients was chest trauma (4 female, 22 male, 31-80 yrs, mean age; 53+/-13 yrs) who were referred to the emergency department in our hospital participated in this tsudy. Technetium-99m diethylene triamine pentaacetic acid (DTPA) aerosol inhalation scintigraphy was performed on the first and thirtieth days after trauma. Clearance half times (T1/2) were calculated by placing a mono-exponential fit on the curves. Penetration index (PI) was calculated on the first-minute image. On the first day, mean T1/2 value of the whole lung was 63+/-19 minutes (min), and thirtieth day mean T1/2 value was 67+/-21 min. On the first day, mean PI values of the lung and 30th day mean PI value were 0.60+/-0.05, and 0.63+/-0.05, respectively. Significant changes were observed in radioaerosol clearance and penetration indices. Following chest trauma, clearance of 99mTc-DTPA increased owing to breakdown of the alveolar-capillary barrier. This increase in the epithelial permeability of the lung appears to be an early manifestation of lung disease that may lead to efficient therapy in the early phase.

To determine the value of aortography in the assessment of occult aortic and great vessel injuries when routinely performed during screening angiography for blunt cerebrovascular injury (BCVI). Methods. One hundred and one consecutive patients who received both aortography and screening four-vessel angiography over 4 years were identified retrospectively. Angiograms for these patients were evaluated, and the incidence of occult mediastinal vascular injury was determined. Results. Of the 101 patients, 6 (6%) had angiographically documented traumatic aortic injuries. Of these 6 patients, one injury (17%) was unsuspected prior to angiography. Four of the 6 (67%) also had BCVI. One additional patient also had an injury to a branch of the subclavian artery. Conclusion. Routine aortography during screening angiography for BCVI is not warranted due to the low incidence (1%) of occult mediastinal arterial injury. However, in the setting of a BCVI screening study and no CT scan of the chest, aortography may be advantageous.

Background and Purpose Sphenoid bone fractures and sphenoid sinus fractures have a high morbidity due to its association with high-energy trauma. The purpose of this study is to describe individuals with traumatic injuries from different mechanisms and attempt to determine if there is any relationship between various isolated or combined fractures of facial skeleton and sphenoid bone and sphenoid sinus fractures. Methods We retrospectively studied hospital charts of all patients who reported to the trauma center at Hospital de San José with facial fractures from December 2009 to August 2011. All patients were evaluated by computed tomography scan and classified into low-, medium-, and high-energy trauma fractures, according to the classification described by Manson. Design This is a retrospective descriptive study. Results The study data were collected as part of retrospective analysis. A total of 250 patients reported to the trauma center of the study hospital with facial trauma. Thirty-eight patients were excluded. A total of 212 patients had facial fractures; 33 had a combination of sphenoid sinus and sphenoid bone fractures, and facial fractures were identified within this group (15.5%). Gender predilection was seen to favor males (77.3%) more than females (22.7%). The mean age of the patients was 37 years. Orbital fractures (78.8%) and maxillary fractures (57.5%) were found more commonly associated with sphenoid sinus and sphenoid bone fractures. Conclusions High-energy trauma is more frequently associated with sphenoid fractures when compared with medium- and low-energy trauma. There is a correlation between facial fractures and sphenoid sinus and sphenoid bone fractures. A more exhaustive multicentric case-control study with a larger sample and additional parameters will be essential to reach definite conclusions regarding the spectrum of fractures of the sphenoid bone associated with facial fractures.

Background. The trauma burden globally accounts for high levels of mortality and morbidity. Blunt abdominal trauma (BAT) contributes significantly to this burden. Patient's evaluation for BAT remains a diagnostic challenge for emergency physicians. SSORTT gives a score that can predict the need for laparotomy. The objective of this study was to assess the accuracy of SSORTT score in predicting the need for a therapeutic laparotomy after BAT. Method. A prospective observational study. Eligible patients were evaluated for shock and the presence of haemoperitoneum using a portable ultrasound machine. Further evaluation of patients following the standard of care (SOC) protocol was done. The accuracy of SSORTT score in predicting therapeutic laparotomy was compared to SOC. Results. In total, 195 patients were evaluated; M : F ratio was 6 : 1. The commonest injuries were to the head 80 (42%) and the abdomen 54 (28%). A SSORTT score of >2 appropriately identified patients that needed a therapeutic laparotomy (with sensitivity 90%, specificity 90%, PPV 53%, and NPV 98%). The overall mortality rate was 17%. Conclusion. Patients with a SSORTT score of 2 and above had a high likelihood of requiring a therapeutic laparotomy. SSORTT scoring should be adopted for routine practice in low technology settings.

Traumatic injury to the knee leads to the development of post-traumatic osteoarthritis. The objective of this study was to characterize the effects of a single intra-articular injection of a non-ionic surfactant, Poloxamer 188 (P188), in preservation of meniscal tissue following trauma through maintenance of meniscal glycosaminoglycan (GAG) content and mechanical properties. Flemish Giant rabbits were subjected to a closed knee joint, traumatic compressive impact with the joint constrained to prevent anterior tibial translation. The contralateral limb served as an un-impacted control. Six animals (treated) received an injection of P188 in phosphate buffered saline (PBS) post trauma, and another six animals (sham) received a single injection of PBS to the impacted limb. Histological analyses for GAG was determined 6 weeks post trauma, and functional outcomes were assessed using stress relaxation micro-indentation. The impacted limbs of the sham group demonstrated a significant decrease in meniscal GAG coverage compared to non-impacted limbs (p<0.05). GAG coverage of the impacted P188 treated limbs was not significantly different than contralateral non-impacted limbs in all regions except the medial anterior (p<0.05). No significant changes were documented in mechanics for either the sham or treated groups compared to their respective control limbs. This suggests that a single intra-articular injection of P188 shows promise in prevention of trauma induced GAG loss.

When requested to evaluate surviving victims of blunt head trauma the forensic expert has to draw mainly on medical documentation from the time of hospital admission. In many cases these consist of written clinical records, radiographs and in some cases photographic documentation of the injuries. We report two cases of survived severe blunt head trauma where CT images, which had primarily been obtained for clinical diagnostic purposes, were used for forensic assessment. 3D reconstructions of the clinical CT-images yielded valuable information regarding the sequence, number and direction of the impacts to the head, their gross morphology and the inflicting weapon. We conclude that computed tomography and related imaging methods, along with their 3D reconstruction capabilities, provide a useful tool to approach questions in clinical forensic casework.

INTRODUCTION Group AB plasma, the traditional universal donor plasma product, is a limited resource. We compared outcomes of Group A plasma transfusion in comparison to AB. METHODS Analysis of blunt-injured patients who received emergency release plasma from was performed. Multivariable logistic regression was utilized to identify associations with morbidity and mortality. RESULTS There were 191 patients; 115 Group A and 76 Group AB. No differences were seen in age, sex, plasma transfusions, uncrossmatched red blood cells (RBCs), and Glasgow Coma Scale (GCS). Patients who received Group A plasma had significantly lower Injury Severity Score, chest Abbreviated Injury Scale, and scene transfer rate but not head AIS, or abdomen AIS. In addition, significant differences were noted in terms of blood products transfused within 24 hours in those receiving Group A over AB. Development of acute respiratory distress syndrome (ARDS), but not mortality, was higher within the AB cohort. No hemolytic or transfusion associated-ARDS reactions were noted in either group. ARDS; RBC transfusion volumes and head AIS were independently associated with mortality. CONCLUSION Utilization of Group A plasma for emergency blood resuscitation is a safe option which may alleviate potential shortages of AB plasma. PMID:25200933

Cardiac contusion is a potentially fatal complication of blunt chest trauma. The effects of a combination of quercetin and methylprednisolone against trauma-induced cardiac contusion were studied. Thirty-five female Sprague-Dawley rats were divided into five groups (n=7) as follows: sham, cardiac contusion with no therapy, treated with methylprednisolone (30 mg/kg on the first day, and 3 mg/kg on the following days), treated with quercetin (50 mg·kg−1·day−1), and treated with a combination of methylprednisolone and quercetin. Serum troponin I (Tn-I) and tumor necrosis factor-alpha (TNF-α) levels and cardiac histopathological findings were evaluated. Tn-I and TNF-α levels were elevated after contusion (P=0.001 and P=0.001). Seven days later, Tn-I and TNF-α levels decreased in the rats treated with methylprednisolone, quercetin, and the combination of methylprednisolone and quercetin compared to the rats without therapy, but a statistical significance was found only with the combination therapy (P=0.001 and P=0.011, respectively). Histopathological degeneration and necrosis scores were statistically lower in the methylprednisolone and quercetin combination group compared to the group treated only with methylprednisolone (P=0.017 and P=0.007, respectively). However, only degeneration scores were lower in the combination therapy group compared to the group treated only with quercetin (P=0.017). Inducible nitric oxide synthase positivity scores were decreased in all treatment groups compared to the untreated groups (P=0.097, P=0.026, and P=0.004, respectively). We conclude that a combination of quercetin and methylprednisolone can be used for the specific treatment of cardiac contusion. PMID:25098616

Abstract A delay in diagnosing hollow viscus injury (HVI) causes an increase in mortality and morbidity. HVI remains a challenge to diagnose, and there is no specific diagnostic biomarker for HVI. We evaluated the utility of intestinal fatty acid–binding protein (I-FABP) in diagnosing HVI in blunt trauma patients. Within a 5-year period, 93 consecutive patients with clinically suspected HVI at our trauma center were prospectively enrolled. The diagnostic performance of I-FABP for HVI was compared with that of other various parameters (physical, laboratory, and radiographic findings). HVI was diagnosed in 13 patients (14%), and non-HVI was diagnosed in 80 patients (86%). The level of I-FABP was significantly higher in patients with HVI than in those with non-HVI (P = 0.014; area under the curve, 0.71). The sensitivity, specificity, positive predictive value, and negative predictive value were 76.9%, 70.0%, 29.4%, and 94.9%, respectively (P = 0.003). However, all other biomarkers were not significantly different between the groups. Presence of extraluminal air, bowel wall thickening on computed tomography (CT), and peritonitis signs were significantly higher in patients with HVI (P < 0.05). Of 49 patients (52.7%) who had a negative I-FABP and negative peritonitis signs, none developed HVI (sensitivity, 100%; negative predictive value, 100%). This is the first study that demonstrated the diagnostic value of a biomarker for HVI. I-FABP has a higher negative predictive value compared to traditional diagnostic tests. Although the accuracy of I-FABP alone was insufficient, the combination of I-FABP and other findings can enhance diagnostic ability. PMID:28272208

This study investigated the implication of a preceding high-trauma fracture on subsequent high- and low-trauma fractures at different skeletal sites in postmenopausal women and similarly aged men at an age range of 54 to 70 years. A preceding high-trauma fracture increases the risk of future low-trauma non-vertebral fractures including hip.

A 67-year-old man suffered a traffic accident and was transferred to an emergency hospital close to the scene. He was diagnosed to have bilateral pneumohemothorax with a lung contusion, an anterior fracture dislocation of the C6-vertebra and a cervical cord injury at the level of C7. On the 48th day, massive hemoptysis was suddenly recognized. He was transferred in a state of shock to our hospital to undergo hemostasis for the bleeding. On the day of admission, a selective arteriogram showed extravasation from the left bronchial artery, for which embolization was carried out using Gelfoam. In spite of this treatment, his hemoptysis continued. On the next day, a selective left internal mammary arteriogram showed an arteriovenous fistula between the left internal mammary artery and the left pulmonary vein without any apparent extravasation. The arteriovenous fistula was successfully embolized using platinum fiber coils. The patient no longer demonstrated any hemoptysis after embolization.

Background Blunt cardiac injury is a rare trauma entity. Here, we sought to evaluate the relevance and prognostic significance of blunt cardiac injury in severely injured patients. Methods In a retrospective multicentre study, using data collected from 47,580 patients enrolled to TraumaRegister DGU (1993-2009), characteristics of trauma, prehospital / hospital trauma management, and outcome analysis were correlated to the severity of blunt cardiac injury. The severity of cardiac injury was assessed according to the abbreviated injury score (AIS score 1-6), the revised injury severity score (RISC) allowed comparison of expected outcome with injury severity-dependent outcome. N = 1.090 had blunt cardiac trauma (AIS 1-6) (2.3% of patients). Results Predictors of blunt cardiac injury could be identified. Sternal fractures indicate a high risk of the presence of blunt cardiac injury (AIS 0 [control]: 3.0%; AIS 1: 19.3%; AIS 2-6: 19.1%). The overall mortality rate was 13.9%, minor cardiac injury (AIS 1) and severe cardiac injury (AIS 2-6) are associated with higher rates. Severe blunt cardiac injury (AIS 4 and AIS 5-6) is associated with a higher mortality (OR 2.79 and 4.89, respectively) as compared to the predicted average mortality (OR 2.49) of the study collective. Conclusion Multiple injured patients with blunt cardiac trauma are at high risk to be underestimated. Careful evaluation of trauma patients is able to predict the presence of blunt cardiac injury. The severity of blunt cardiac injury needs to be stratified according to the AIS score, as the patients’ outcome is dependent on the severity of cardiac injury. PMID:26136126

, severe permanent hemiplegia in two cases, and minimal or no sequels in two cases. Following blunt trauma, arteriography of supraaortic vessels should be performed to detect BCAD in any patient with immediate or delayed neurologic symptoms that cannot be explained by CT-scan findings. To better understand the natural course of these lesions and define the indications for surgery, we propose a three-grade classification according to arteriographic findings. If surgery is undertaken, vein grafting should be performed following resection of the carotid artery lesions.

Traumatic hemothorax commonly occurs accompanied by organ damage, such as rib fractures, lung injury and diaphragm rupture. Our reported patient was a 61-year-old man who fell down from a stepladder about 1 meter in height, resulting in a heavy blow to the left abdomen. He consulted a clinic because of left chest pain the next day and was transported to the emergency center of our hospital on diagnosis of hemothorax with hemorrhagic shock.On computed tomography scanning with contrast medium, left hemothorax without rib fracture, diaphragm rupture or obvious organ injury was evident. We found only bleeding to the thoracic space from a branch of the left inferior phrenic artery without involvement of the abdomen. The patient underwent percutaneous angiography and embolization for hemostasis, and subsequently thoracotomy in order to check the active bleeding and remove the hematoma to improve respiratory. As thoracotomy findings, we found damage of a branch of the left inferior phrenic artery to the thoracic space without diaphragm rupture, and sutured the lesion. Such active intervention followed by surgical procedures was effective and should be considered for rare occurrences like the present case. We must consider not only traumatic diaphragm rupture, but also vascular damage by pressure trauma as etiological factors for hemothorax.

The incidence of facial trauma is high. This study has the primary objective of documenting and cataloging maxillofacial fractures in polytrauma patients. From a total of 1229 multiple trauma cases treated at the Emergency Room of the Santo Antonio Hospital - Oporto Hospital Center, Portugal, between August 2001 and December 2007, 251 patients had facial wounds and 209 had maxillofacial fractures. Aged ranged form 13 to 86 years. The applied selective method was based on the presence of facial wound with Abbreviated Injury Scale ≥1. Men had a higher incidence of maxillofacial fractures among multiple trauma patients (86.6%) and road traffic accidents were the primary cause of injuries (69.38%). Nasoorbitoethmoid complex was the most affected region (67.46%) followed by the maxilla (57.42%). The pattern and presentation of maxillofacial fractures had been studied in many parts of the world with varying results. Severe multiple trauma patients had different patterns of maxillofacial injuries. The number of maxillofacial trauma is on the rise worldwide as well as the incidence of associated sequelae. Maxillofacial fractures on multiple trauma patients were more frequent among males and in road traffic crashes. Knowing such data is elementary. The society should have a key role in the awareness of individuals and in prevention of road traffic accidents.

This study assessed the impact of oral and maxillofacial trauma and surgical treatment on the quality of life of patients. The study included 66 patients (age range 18-65 years) with facial fractures; 33 required surgical treatment and 33 required conservative (non-surgical) treatment. Quality of life was evaluated by applying the Oral Health Impact Profile questionnaire (OHIP-14) immediately after diagnosis of the trauma (T1), 30 days after surgery or trauma (T2), and 90 days after surgery or trauma (T3). For the control group (conservative treatment), there was a change in quality of life at T1 and T2. A change in quality of life was found for all of the surgical patients, regardless of the type of fracture and the observation period analyzed. There was no statistical difference when T1, T2, and T3 were compared in cases of zygomatic, Le Fort I, and nasal fractures, however there was an improvement in the quality of life of patients with mandibular fractures (P=0.0102) and multiple facial fractures (P=0.0097) at T3. Facial trauma caused the greatest impact on the quality of life of surgical patients at T1. The surgical treatment significantly improved quality of life for patients with mandibular and multiple facial fractures.

Until today the mortality of complex pelvic trauma remains unacceptably high. On the one hand this could be attributed to a biological limit of the survivable trauma load, on the other hand side an ongoing inadequate treatment might be conceivable too. For the management of multiple trauma patients with life-threatening pelvic fractures, there is ongoing international debate on the adequate therapeutic strategy, e.g. arterial embolization or pelvic packing, as well as aggressive or restrained volume therapy. Whereas traditional pelvis-specific trauma algorithms still recommend massive fluid resuscitation, there is upcoming evidence that a restrained volume therapy in the preclinical setting may improve trauma outcomes. Less intravenous fluid administration may also reduce haemodilution and concomitant trauma-associated coagulopathy. After linking the data of the TraumaRegister DGU(®) and the German Pelvic Injury Register, for the first time, the initial fluid management for complex pelvic traumas as well as for different Tile/OTA types of pelvic ring fractures could be addressed. Unfortunately, the results could not answer the question of the adequate fluid resuscitation but confirmed the actuality of massive fluid resuscitation in the prehospital and emergency room setting. Low-volume resuscitation seems not yet accepted in practice in managing multiple trauma patients with pelvic fractures at least in Germany. Nevertheless, prevention of exsanguination and of complications like multiple organ dysfunction syndrome still poses a major challenge in the management of complex pelvic ring injuries. Even nowadays, fluid management for trauma, not only for pelvic fractures, remains a controversial area and further research is mandatory.

IMPORTANCE Increased use of computed tomography (CT) in children is concerning owing to the cancer risk from ionizing radiation, particularly in children younger than 2 years. A guardian report that a child is acting abnormally is a risk factor for clinically important traumatic brain injury (ciTBI) and may be a driving factor for CT use in the emergency department. OBJECTIVE To determine the prevalence of ciTBIs and TBIs in children younger than 2 years with minor blunt head trauma and a guardian report of acting abnormally with (1) no other findings or (2) other concerning findings for TBI. DESIGN, SETTING, AND PARTICIPANTS Secondary analysis of a large, prospective, multicenter cohort study that included 43 399 children younger than 18 years with minor blunt head trauma evaluated in 25 emergency departments. The study was conducted on data obtained between June 2004 and September 2006. Data analysis was performed between August 21, 2014, and March 9, 2015. EXPOSURES A guardian report that the child was acting abnormally after minor blunt head trauma. MAIN OUTCOMES AND MEASURES The prevalence of ciTBI (defined as death, neurosurgery, intubation for >24 hours, or hospitalization for ≥2 nights in association with TBI on CT imaging) and TBI on CT imaging in children with a guardian report of acting abnormally with (1) no other findings and (2) other concerning findings for TBI. RESULTS Of 43 399 children in the cohort study, a total of 1297 children had reports of acting abnormally, of whom 411 (31.7%) had this report as their only finding. Reported as percentage (95% CI), 1 of 411 (0.2% [0–1.3%]) had a ciTBI, and 4 TBIs were noted on the CT scans in 185 children who underwent imaging (2.2% [0.6%–5.4%]). In children with reports of acting abnormally and other concerning findings for TBI, 29 of 886 (3.3% [2.2%–4.7%]) had ciTBIs and 66 of 674 (9.8% [7.7%–12.3%]) had TBIs on CT. CONCLUSIONS AND RELEVANCE Clinically important TBIs are very uncommon, and TBIs

Blunt traumatic injury is one of the leading causes of morbidity and mortality in the United States. Unintentional injury represents the leading cause of death in the United States for all persons between the ages of 1 and 44 years. In the setting of blunt abdominal trauma, the reported rate of occurrence of bowel and mesenteric injuries ranges from 1% to 5%. Despite the relatively low rate of blunt bowel and mesenteric injury in patients with abdominal and pelvic trauma, delays in diagnosis are associated with increased rates of sepsis, a prolonged course in the intensive care unit, and increased mortality. During the past 2 decades, as multidetector computed tomography (CT) has emerged as an essential tool in emergency radiology, several direct and indirect imaging features have been identified that are associated with blunt bowel and mesenteric injury. The imaging findings in cases of blunt bowel and mesenteric injury can be subtle and may be seen in the setting of multiple complex injuries, such as multiple solid-organ injuries and spinal fractures. Familiarity with the various imaging features of blunt bowel and mesenteric injury, as well as an understanding of their clinical importance with regard to the care of the patient, is essential to making a timely diagnosis. Once radiologists are familiar with the spectrum of findings of blunt bowel and mesenteric injury, they will be able to make timely diagnoses that will lead to improved patient outcomes.

We herein report an extremely rare case of a patient chylothorax at an interval of 20 years after thoracic vertebrae fractures, who underwent a successful thoracoscopic thoracic duct ligation and pleurodesis. A 51-year-old man was referred to our hospital with shortness of breath on effort about 1 month after participating in archery. Twenty years previously, he was involved in a traffic accident. At that time, the patient sustained trauma to the spine and suffered a spinal injury, thus resulting in paralysis in the lower part of his body. A chest roentgenogram and computed tomogram revealed a large amount of bilateral pleural effusion. After thoracentesis was performed, a diagnosis of chylothorax was made and the patient was hospitalized. Conservative management by a low-fat diet proved to be unsuccessful. The patient did not request pleurodesis, because pleural adhesions might impair pulmonary function. As a result, we decided to perform surgery. On the right side, we performed video-assisted thoracoscopic surgery by clipping the thoracic duct and applying an absorbable sealing material. Thereafter, pleurodesis was performed and OK-432 was instilled. Thereafter, the pleural fluid flow was almost completely stopped. On the left side, pleurodesis was effective. The patient has since remained symptom free and has been followed up on an outpatient basis for 9 months after the 100th postoperative day. We assumed that the chylothorax in this case was related to the earlier traffic accident.

Background Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions. Methods This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching. Results In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1%) underwent emergency resuscitative thoracotomy and 893 (64.9%) received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001) and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001). Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h

We report a case of fractured occipital condyle caused by minor trauma accompanied by light pain on palpation at the lateral cervical trigonum. A 15-year-old boy complained of nuchal pain, particularly pain on palpation at the left lateral cervical trigonum in the absence of neurologic deficits after head deceleration trauma. Computed tomography demonstrated a unilateral nonluxated fracture of the occipital condyle. Owing to consequent immobilization by means of cervical orthosis, pain disappeared after the first 48 hours. Follow-up examination 4 weeks later showed no neurologic deficits. The boy had no severe impairment of movements at the cervical spine.

For any patient with obvious or suspected chest trauma, one must first assure an adequate airway and adequate ventilation. One should never hesitate to administer oxygen to a victim with a chest injury. The nurse should be concerned with adequate circulation--this may mean the administration of intravenous fluids, specifically volume expanders, via large-bore cannulae. Any obvious open chest wound should be sealed, and any fractures should be splinted. These patients should be rapidly transported to the nearest Emergency Department capable of handling this type of injury. The majority of patients who arrive in the Emergency Department following blunt or penetrating trauma should be considered to be in critical condition until proven otherwise. On presentation, it is essential to recognize those signs, symptoms, and laboratory values that identify the patient's condition as life-threatening. Simple recognition of these signs and symptoms and early appropriate intervention may alter an otherwise fatal outcome.

Background: The work presents the assessment of the results of treatment of open tibial shaft fractures in polytrauma patients. Materials and Methods: The study group comprised 28 patients who underwent surgical treatment of open fractures of the tibial shaft with locked intramedullary nailing. The mean age of the patients was 43 years (range from 19 to 64 years). The criterion for including the patients in the study was concomitant multiple trauma. For the assessment of open tibial fractures, Gustilo classification was used. The most common concomitant multiple trauma included craniocerebral injuries, which were diagnosed in 12 patients. In 14 patients, the surgery was performed within 24 h after the injury. In 14 patients, the surgery was delayed and was performed 8–10 days after the trauma. Results: The assessment of the results at 12 months after the surgery included the following features: time span between the trauma and the surgery and complications in the form of osteomyelitis and delayed union. The efficacy of gait, muscular atrophy, edema of the operated limb and possible disturbances of its axis were also taken under consideration. In patients operated emergently within 24 h after the injury, infected nonunion was observed in three (10.8%) males. These patients had grade III open fractures of the tibial shaft according to Gustilo classification. No infectious complications were observed in patients who underwent a delayed operation. Conclusion: Evaluation of patients with open fractures of the tibial shaft in multiple trauma showed that delayed intramedullary nailing performed 8–10 days after the trauma, resulted in good outcome and avoided development of delayed union and infected nonunion. This approach gives time for stabilization of general condition of the patient and identification of pathogens from wound culture. PMID:19753226

Summary We present a 44-year-old female patient with recurrent fragility fractures including an intercondylar femoral fracture and with normal planar bone densitometry. Diagnosis of hypophosphatasia was suggested by low volumetric cortical bone mineral density and laboratory findings. DNA sequencing revealed heterozygous mutations in the exons 5, 6 and 9 of the ALPL gene, thus confirming the suspected diagnosis. PMID:27920814

Objectives: Complicated fracture healing is often associated with the severity of surrounding muscle tissue trauma. Since inflammation is a primary determinant of musculoskeletal health and regeneration, it is plausible that delayed healing and non-unions are partly caused by compounding local inflammation in response to concomitant muscle trauma. Methods and results: To investigate this possibility, a Lewis rat open fracture model [tibia osteotomy with adjacent tibialis anterior (TA) muscle volumetric muscle loss (VML) injury] was interrogated. We observed that VML injury impaired tibia healing, as indicated by diminished mechanical strength and decreased mineralized bone within the fracture callus, as well as continued presence of cartilage instead of woven bone 28 days post-injury. The VML injured muscle presented innate and adaptive immune responses that were atypical of canonical muscle injury healing. Additionally, the VML injury resulted in a perturbation of the inflammatory phase of fracture healing, as indicated by elevations of CD3+ lymphocytes and CD68+ macrophages in the fracture callus at 3 and 14d post-injury, respectively. Conclusions: These data indicate that heightened and sustained innate and adaptive immune responses to traumatized muscle are associated with impaired fracture healing and may be targeted for the prevention of delayed and non-union following musculoskeletal trauma.

Individuals with intellectual and developmental disabilities (IDD) are at risk for low-trauma fractures. We investigated the rate of low-trauma fractures and the odds of BMD testing in adults with/without IDD. Adults with IDD were more likely to have a low-trauma fracture, but there was no difference in bone mineral density (BMD) testing rates.

Background. Previous studies showed significant interaction between the local and systemic inflammatory response after severe trauma in small animal models. The purpose of this study was to establish a new combined trauma model in pigs to investigate fracture-associated local inflammation and gain information about the early inflammatory stages after polytrauma. Material and Methods. Combined trauma consisted of tibial fracture, lung contusion, liver laceration, and controlled hemorrhage. Animals were mechanically ventilated and under ICU-monitoring for 48 h. Blood and fracture hematoma samples were collected during the time course of the study. Local and systemic levels of serum cytokines and diverse alarmins were measured by ELISA kit. Results. A statistical significant difference in the systemic serum values of IL-6 and HMGB1 was observed when compared to the sham. Moreover, there was a statistical significant difference in the serum values of the fracture hematoma of IL-6, IL-8, IL-10, and HMGB1 when compared to the systemic inflammatory response. However a decrease of local proinflammatory concentrations was observed while anti-inflammatory mediators increased. Conclusion. Our data showed a time-dependent activation of the local and systemic inflammatory response. Indeed it is the first study focusing on the local and systemic inflammatory response to multiple-trauma in a large animal model.

Background The talus has a very complex anatomical morphology and is mainly fractured by a major force caused by a fall or a traffic accident. Therefore, a talus fracture is not common. However, many recent reports have shown that minor injuries, such as sprains and slips during sports activities, can induce a talar fracture especially in the lateral or posterior process. Still, fractures to the main parts of the talus (neck and body) after ankle sprains have not been reported as occult fractures. Methods Of the total 102 cases from January 2005 to December 2012, 7 patients had confirmed cases of missed/delayed diagnosis of a talus body or neck fracture and were included in the study population. If available, medical records, X-rays, computed tomography scans, and magnetic resonance imaging of the confirmed cases were retrospectively reviewed and analyzed. Results In the 7-patient population, there were 3 talar neck fractures and 4 talar body fractures (coronal shearing type). The mechanisms of injuries were all low energy trauma episodes. The causes of the injuries included twisting of the ankle during climbing (n = 2), jumping to the ground from a 1-m high wall (n = 2), and twisting of the ankle during daily activities (n = 3). Conclusions A talar body fracture and a talar neck fracture should be considered in the differential diagnosis of patients with acute and chronic ankle pain after a minor ankle injury. PMID:27583114

Objective: To present the case of a 17-year-old male soccer goalkeeper who sustained maxillofacial fractures and dental trauma after being struck in the face by an opponent's knee. Background: Because of the nature of the sport and a lack of protective headgear, soccer players are at risk for sustaining maxillofacial trauma. Facial injuries can complicate the routine management of on-field medical emergencies often encountered by certified athletic trainers. The appropriate management of maxillofacial trauma on the playing field may help to reduce both the immediate and long-term morbidity and mortality associated with these injuries. Differential Diagnosis: Lacerated superior labial artery, lacerated upper lip, dental fractures, maxillofacial fractures, orbital blowout fracture, closed head injury, cervical spine injury, cerebrovascular accident. Treatment: The athlete received immediate on-field medical care and was subsequently transported to the hospital, where diagnostic testing was performed and further treatment was provided. Hospital inpatient management included dental and plastic surgery. After discharge from the hospital, the athlete underwent several additional dental procedures, including gingival surgery and nonsurgical endodontic treatments. The fractures were followed closely to assure that adequate healing had occurred. The athlete did not return to soccer. Uniqueness: Certified athletic trainers need to be prepared for on-field medical emergencies. Bleeding associated with maxillofacial trauma can complicate basic medical interventions such as airway maintenance. Inappropriate on-field management may result in unnecessary morbidity and mortality for the injured athlete. Therefore, immediate recognition of the severity of the injury is needed in order to institute appropriate airway-management strategies. Conclusions: It is sometimes necessary to consider nonstandard methods of airway management in order to first address heavy bleeding that may be

Head-splitting fractures occur as a result of violent compression of the head against the glenoid; the head splits and the tuberosities may remain attached to the fragments or split and separate. Isolated humeral head-splitting fractures are rare injuries. Favorable results with osteosynthesis can be difficult to achieve because of the very proximal location of the head fracture and associated poor vascularity. We present a case of a 67-year-old man who sustained a severe, sword-like trauma to his left shoulder after a road traffic accident with associated isolated open Gustilo-Anderson IIIA humeral head-splitting fracture. Bony union was achieved with minimal internal fixation but the clinical outcome deteriorated due to accompanying axillary nerve apraxia. To our knowledge, this type of sword-like injury with associated humeral head-split fracture has not previously been reported. PMID:27478665

Records of 100 consecutive patients treated in 1973 through 1977 with post-traumatic retroperitoneal hematomas (RH) were studied. Eighty RH followed blunt injury and 20 were due to penetrating trauma. Overall mortality was 26%. The worst prognosis was associated with RH from automobile accidents and pedestrian injuries. Pelvic RH were almost uniformly associated with pelvic fracture and were the primary cause of 39% of deaths. Blunt perinephric RH required renal exploration in 47% of patients. Blunt RH in other locations were associated with major visceral or vascular injury in half the patients and were the cause of death in five. Sixty-five per cent of RH due to penetrating trauma had visceral or vascular injury requiring operative correction. Contained rupture of descending choracic aorta presented as retrogastric RH in two patients. RH from penetrating trauma should be explored routinely, since 65% are associated with visceral or vascular injury.

Blunt Cardiac Rupture (BCR) is a life threatening injury. Majority of patients do not reach the hospital and in those who reach the emergency department, timely diagnosis and treatment is a challenge. The case is about a patient with multiple blunt injuries who presented in shock. Cardiac tamponade was suspected on clinical grounds and on evidence of mediastinal widening on radiograph. In the absence of songography, the diagnosis was confirmed by subxiphoid pericardial window. Emergency thoracotomy revealed a right atrial appendage rupture which was surgically corrected. The patient also underwent splenectomy for grade IV splenic injury. Liver injury, pubic diastasis and tibial spine avulsion fracture was managed conservatively. He recovered well. Systematic observance of trauma resuscitation guidelines can help salvage patients with life threatening complex injuries even in the absence of specialized imaging investigations. PMID:28050441

Abstract As pelvic fractures in children and adolescents are very rare, the surgical management is not well delineated nor are the postoperative complications. The aim of this study using the prospective data from German Pelvic Trauma Registry study was to evaluate the various treatment approaches compared to adults and delineated the differences in postoperative complications after pelvic injuries. Using the prospective pelvic trauma registry established by the German Society of Traumatology and the German Section of the Arbeitsgemeinschaft für Osteosynthesefragen (AO), International in 1991, patients with pelvic fractures over a 12-year time frame submitted by any 1 of the 23 member level I trauma centers were reviewed. We identified a total of 13,525 patients including pelvic fractures in 13,317 adults and 208 children aged ≤14 years and compared these 2 groups. The 2 groups’ Injury Severitiy Score (ISS) did not differ statistically. Lethality in the pediatric group was 6.3%, not statistically different from the adults’ 4.6%. In all, 18.3% of the pediatric pelvic fractures were treated surgically as compared to 22.7% in the adult group. No child suffered any thrombosis/embolism, acute respiratory distress syndrome (ARDS), multiorgan failure (MOF), or neurologic deficit, nor was any septic MOF detected. The differences between adults and children were statistically significant in that the children suffered less frequently from thrombosis/embolism (P = 0.041) and ARDS and MOF (P = 0.006). This prospective multicenter study addressing patients with pelvic fractures reveals that the risk for a thrombosis/embolism, ARDS, and MOF is significant lower in pediatric patients than in adults. No statistical differences could be found in the ratios of operative therapy of the pelvic fractures in children compared to adults. PMID:26705223

Objectives: To determine whether a time delay greater than 6h from injury to surgical debridement influences the infection rate in open fractures. Methods: During a period of 18 months, from October 2010 to March 2012, 151 open fractures were available for study in 142 patients in our hospital. The data were collected prospectively and the patients were followed up for 6 weeks. The patients were divided into two groups regarding the time delay from injury to surgical debridement (more or less than 6 hours). Results: Surgical debridement was carried out in less than 6h from injury in 90 (59.6%) fractures and after 6 hours from injury in 61 (40.4%) fractures. Infection rates were 12.22% and 13.24%, respectively. The global infection rate was 13.24%. Conclusion: A significantly increased infection rate was not observed in patients whose surgical debridement occurred more than 6h after injury. However, in the fractures of high-energy trauma, a statistically significant increase of the rate of infection was observed in those operated 6 hours after trauma. Level of Evidence II, Study Type Comparative and Prospective. PMID:26327794

Despite numerous studies on high impact fractures of ribs, little is known about compressive rib injuries. We studied rib fractures from a biomechanical and morphological perspective using 15, 5th ribs of domestic pigs Sus scrofa, divided into two groups, desiccated (representing post-mortem trauma) and fresh ribs with intact periosteum (representing peri-mortem trauma). Ribs were axially compressed and subjected to four-point bending in an Instron 3339 fitted with custom jigs. Morphoscopic analysis of resultant fractures consisted of standard optical methods, micro-CT (μCT) and scanning electron microscopy (SEM). During axial compression, fresh ribs had slightly higher strength because of energy absorption capabilities of their soft and fluidic components. In flexure tests, dry ribs showed typical elastic-brittle behaviour with long linear load-extension curves, followed by relatively short non-linear elastic (hyperelastic) behaviour and brittle fracture. Fresh ribs showed initial linear-elastic behaviour, followed by strain softening, visco-plastic responses. During the course of loading, dry bone showed minimal observable damage prior to the onset of unstable fracture. In contrast, fresh bone showed buckling-like damage features on the compressive surface and cracking parallel to the axis of the bone. Morphologically, all dry ribs fractured precipitously, whereas all but one of the fresh ribs showed incomplete fracture. The mode of fracture, however, was remarkably similar for both groups, with butterfly fractures predominating (7/15, 46.6% dry and wet). Our study highlights the fact that under controlled loading, despite seemingly similar butterfly fracture morphology, fresh ribs (representing perimortem trauma) show a non-catastrophic response. While extensive strain softening observed for the fresh bone does show some additional micro-cracking damage, it appears that the periosteum may play a key role in imparting the observed pseudo-ductility to the ribs

Targeted temperature management (TTM) improves survival and neurological outcome after nontraumatic cardiac arrest. However, TTM is not used widely after traumatic cardiac arrest because of concerns that it might exacerbate bleeding. We report the use of postarrest TTM after repair of blunt myocardial rupture. A 48-year-old man was admitted after being rescued from a major traffic accident by the local emergency service. Focused sonography showed pericardial fluid without cardiac tamponade. Computed tomography showed a large hematoma in the anterior mediastinum associated with hemopericardium. The patient developed cardiac arrest during the operative preparations. Repeat bedside sonography revealed a large pericardial effusion and signs of cardiac tamponade. Spontaneous circulation was restored after ultrasound-guided pericardiocentesis. His Glasgow Coma Scale score was 3. The patient was transported promptly to the operating room and underwent median sternotomy without cardiopulmonary bypass. A rupture of the junction of the superior vena cava/right atrium and left atrial appendage was detected and was closed by direct suturing. Immediately after return to the intensive care unit, we performed TTM (target body temperature 34.5°C) using a surface-cooling device at 4 hours postarrest. TTM was maintained for 24 hours and controlled gradual rewarming was then initiated. He regained consciousness 36 hours postrewarming with limited speech ability. The patient recovered with no further cardiac events and was discharged 3 weeks after admission, with no other serious complications. The patient was neurologically intact (cerebral performance category 1) at 6 months of follow-up. This case demonstrates the potential benefit and applicability of postarrest TTM in patients after repair of blunt myocardial rupture.

Areal bone mineral density (BMD) by DXA, although an important index, does not accurately assess risk of fragility fracture. Another bone structural parameter, the orientation of type I collagen, is known to add to risk determination, independently of BMD. Accordingly, we investigated the Haversian systems of transiliac crest biopsies from non-osteoporotic women with low-trauma fractures, matched to healthy women without fracture by age and BMD. We employed circularly polarized light (CPL) microscopy because 1) each of the extinct and bright birefringent signals of CPL corresponds to a specific collagen arrangement; and 2) CPL can employ magnification suitable to provide data, of manageable size, from the whole cortical component of a section of biopsy. Under CPL, the coaxial layers of osteons, called lamellae, appear either birefringent extinct or bright. On a section transverse to the Haversian system, the extinct lamella comprises mainly collagen forming small angles, and the bright lamella comprises mainly collagen forming large angles, relative to the general orientation of the Haversian system. We performed semi-automatic morphometry for birefringent and structural parameters for which we computed intra- and inter-observer errors. The statistical analysis used a linear mixed model to compare fracturing and non-fracturing groups while addressing pairing of fracturing and non-fracturing subjects, and linear regression to assess differences between matched subjects. We found significant reduction in 1) lamellar width and area for extinct lamella and bright lamella; 2) percentage of extinct birefringence in osteons, and 3) single osteon area; in the fracturing group; and in lamellar width in the fracturing subject of all pairs. Our results evidence the need to investigate, in a larger sample of subjects, the distribution of collagen orientation as a parameter diagnostic of increased fracture risk.

We report the case of a 19-year-old male soldier, who sustained stress fractures of the hamate body and fourth metacarpal base due to his daily knuckle push-up routine in the military. We introduce repetitive microtrauma due to daily knuckle push-ups as an unusual, but potential trauma mechanism for metacarpal and carpal stress fractures.

Mandibular fracture is a common occurrence in emergency medicine and belongs to the most frequent facial fractures. Historically road traffic injuries (RTIs) have played a prominent role as a cause for mandibular fractures. We extracted data from all patients between August 2012 and February 2015 with “lower jaw fracture” or “mandibular fracture” from the routine database from the emergency department. We conducted a descriptive analysis at a Swiss level one trauma centre. 144 patients were admitted with suspected mandibular fractures. The majority underwent CT diagnostic (83%). In 7% suspected mandibular fracture was not confirmed. More than half of all patients suffered two or more fractures. The fractures were median or paramedian in 77/144 patients (53%) and in other parts (corpus, mandibular angle, ramus mandibularis, collum, and temporomandibular joint) in 100/144 (69%). Male to female ratio was 3 : 1 up to 59 years of age; 69% were younger than 40 years. 72% of all patients presented during daytime, 69% had to be hospitalized, and 31% could be discharged from the ED after treatment. Most fractures were due to fall (44%), followed by interpersonal violence (25%) and sport activities (12%). Falls were a dominant cause of fracture in all age groups while violence and sport activities were common only in younger patients. Comparisons to other studies were difficult due to lack of standardization of causes contributing to the injuries. In the observed time period and setting RTIs have played a minor role compared to falls, interpersonal violence, and sports. In the future, standardized documentation as well as categorization of causes for analytic purposes is urgently needed to facilitate international comparison of studies. PMID:27656297

PurposeTo compare the impact of proximal or distal splenic artery embolisation versus that of splenectomy on splenic immune function as measured by IgM memory B cell levels.Materials and MethodsPatients with splenic trauma who were treated by splenic artery embolisation (SAE) were enrolled. After 6 months splenic volume was assessed by CT, and IgM memory B cells in peripheral blood were measured and compared to a local normal reference population and to a post-splenectomy population.ResultsOf the 71 patients who underwent embolisation, 38 underwent proximal embolisation, 11 underwent distal embolisation, 22 patients were excluded, 1 had both proximal and distal embolisation, 5 did not survive and 16 did not return for evaluation. There was a significant difference between splenectomy and proximal or distal embolisation and a trend towards greater preservation of IgM memory B cell number in those with distal embolisation—a difference that could not be attributed to differences in age, grade of injury or residual splenic volume.ConclusionIgM memory B cell levels are significantly higher in those treated with SAE compared to splenectomy. Our data provide evidence that splenic embolisation should reduce immunological complications of spleen trauma and suggest that distal embolisation may maintain better function.

In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation. It is child-friendly and diagnostic capabilities have been improved with the advent of contrast-enhanced ultrasound (CEUS). The application of CEUS is indeed promising. However, no ultrasound contrast agent manufactured today is registered for pediatric use in Europe. The contrast agent SonoVue(®) has recently been approved by the FDA under the name of Lumason(®) to be used in hepatic investigations in adults and children. This article reviews the literature with respect to 2 specific applications of CEUS in children: 1) identification of parenchymal injuries following blunt abdominal trauma, and 2) classification of focal liver lesions. Applications were chosen through the CEUS guidelines published by the European Federation of Societies for Ultrasound in Medicine and Biology and World Federation for Ultrasound in Medicine and Biology. Literature was obtained by searching Medline and Pubmed Central (using Pubmed), Scopus database and Embase. CEUS proved to be an effective investigation in the hemodynamically stable child for identifying parenchymal injuries and for the characterization of focal liver lesions. CEUS showed comparable performance to CT and MRI with a specificity of 98% for identifying benign lesions and a negative predictive value of 100%. For the applications reviewed here, CEUS holds promising perspectives and can help reduce radiation exposure and use of iodinated contrast agents in pediatrics, thereby potentially reducing complications in routine imaging.

We hypothesized that elevated base deficit (BD) ≥ 4 mEq/L upon admission could be associated with an altered inflammatory response, which in turn may impact differential clinical trajectories. Using clinical and biobank data from 472 blunt trauma survivors, 154 patients were identified after excluding patients who received prehospital IV fluids or had alcohol intoxication. From this subcohort, 84 patients had a BD ≥ 4 mEq/L and 70 patients with BD < 4 mEq/L. Three samples within the first 24 h were obtained from all patients and then daily up to day 7 after injury. Twenty-two cytokines and chemokines were assayed using Luminex™ and were analyzed using two-way ANOVA and dynamic network analysis (DyNA). Multiple mediators of the innate and lymphoid immune responses in the BD ≥ 4 group were elevated differentially upon admission and up to 16 h after injury. DyNA revealed a higher, sustained degree of interconnectivity of the inflammatory response in the BD ≥ 4 patients during the initial 16 h after injury. These results suggest that elevated admission BD is associated with differential immune/inflammatory pathways, which subsequently could predispose patients to follow a complicated clinical course.

According to the CDC, the leading cause of death for both men and women between the ages of 5 and 44 is traumatic injury. Blood loss is the primary cause of death at acute time points post trauma. Early intervention is critical to save lives, and yet there are no treatments to stop internal bleeding that can be deployed in the field. In this work, we developed hemostatic nanoparticles that are stable at high temperatures (50 °C for 7 days) and are still effective at stopping bleeding and improving survival over the one hour time period in a rat liver injury model. These particles are exceptionally simple: PLA-based nanospheres functionalized with PEG terminated with variants of the RGD motif. This simple system can be stored at temperatures up to 50°C and maintain size, shape, and efficacy. The particles lead to a reduction in bleeding and increased acute survival with significance compared to both control particles and saline. Overall, these hemostatic nanoparticles offer an important step towards an immediate intervention in the field to stop bleeding and improve survival. PMID:27672679
The most common treatment option for postmenopausal osteoporosis are the bisphosphonates which inhibit osteoclast function. Bisphosphonates interfere with cellular metabolism and in large clinical trials reduce risk of vertebral and non-vertebral fractures. Zoledronic acid is a potent bisphosphonate also approved for the treatment of postmenopausal osteoporosis. In addition zoledronic acid reduce relative risk of any new clinical fracture after surgical repair of low-trauma hip fracture. Also the reduction in the relative risk of death was observed after repeated once-yearly intravenous infusion. In conclusion, this is another interesting option for the treatment of the patients affected with osteoporosis and previous hip fractures.

A limited number of studies have described the epidemiology of open fractures, and the epidemiology of open ankle fractures is not an exception. Therefore, the risk factors associated with open ankle fractures have not been extensively evaluated. The frequencies and proportions of open ankle fractures among all the recorded malleolar fractures in the US National Trauma Data Bank data set from January 2007 to December 2011 were analyzed. Clinically relevant variables captured in the data set were also used to evaluate the risk factors associated with open ankle fractures, adjusting for other covariates. The entire cohort was further subdivided into "lower" and "higher" energy trauma groups and the same analysis performed for each group separately. We found that a body mass index of >40 kg/m(2) and farm location were risk factors for open ankle fractures and impaired sensorium was protective against open ankle fractures. In the "lower energy" group, male gender, alcohol use, peripheral vascular disease, other injuries, and injury occurring at a farm location were risk factors for open fractures. In the "higher energy" group, female gender, work-related injury, and injury at a farm or industry location demonstrated statistically significantly associations with open fractures.

Summary Background magnetic resonance imaging (MRI) as a noninvasive diagnostic tool may help clinicians in the evaluation of injuries to menisci and ligaments. Purpose this study assessed the associations between type of trauma to knee joint, bone bruise, fracture and pathological joint effusion with injuries to menisci and ligaments of knee joint. Methods we reviewed knee joint MRI of 175 patients aged less than 45 years old who were referred to MRI center of our University. Results statistical analysis showed that tearing of medial meniscus (MM) is significantly more common in sport related trauma (p= 0.045) but tearing of medial collateral ligament (MCL) is significantly more common in non-sport related trauma (p= 0.005). Existence of bone bruise in knee MRI is negatively associated with tearing of medial meniscus (MM) (p=0.004) and positively associated with tearing of anterior cruciate ligament (ACL) (p=0.00047) and medial collateral ligament (MCL) (p = 0.0001). Existence of fracture is associated with decreased risk of the tearing of ACL and MM (p=0.04, p=0.001 respectively). Pathologic joint effusion is significantly more common in ACL and MCL tearing (p=0.0001, p=0.004 respectively). Conclusions as diagnostic clues, bone bruise, fracture and joint effusion may help radiologists for better assessment of injury to menisci and ligaments in MRI of patients with knee trauma.

An 8-year-old male Jack Russell crossbreed dog was admitted to our hospital with dyspnea and shock following a dog-bite injury on the ventral neck. Radiographs revealed subcutaneous emphysema and bilateral thyrohyoid bone fractures. Intraoperatively, rupture of both sternohyoid muscles, both hyoepiglotticus muscles, both thyrohyoid muscles, and a partial cranial rupture of the superficial sphincter colli muscle were detected. Part of the epiglottis was detached from the thyroid cartilage. The patient’s severed muscles and torn epiglottis were reattached using a simple interrupted suture pattern. Hyoepiglotticus muscles could not be identified. The bilateral thyrohyoid bone fractures were repaired with intraosseous wire suture. A temporary tracheostomy tube and an esophageal feeding tube were placed postoperatively. The dog was discharged after 8 days, re-examined at 2 and 6 months and laryngeal and pharyngeal function were evaluated as normal. To the authors’ knowledge, this is the first report of a dog that presented with laryngeal trauma with hyoid bone fracture and acute dyspnea that underwent surgical treatment resulting in an acceptable outcome.

Thoracic trauma remains a major source of morbidity and mortality in injured children, and is second only to brain injuries as a cause of death. The presence of a chest injury increases an injured child's mortality by 20-fold. Greater than 80% of chest injuries in children are secondary to blunt trauma. The compliant chest wall in children makes pulmonary contusions and rib fractures the most common chest injuries in children. Injuries to the great vessels, esophagus, and diaphragm are rare. Failure to promptly diagnose and treat these injuries results in increased morbidity and mortality.

Children and adolescents who sustain a distal forearm fracture (DFF) owing to mild, but not moderate, trauma have reduced bone strength and cortical thinning at the distal radius and tibia. Whether these skeletal deficits track into adulthood is unknown. Therefore, we studied 75 women and 75 men (age range, 20 to 40 years) with a childhood (age < 18 years) DFF and 150 sex-matched controls with no history of fracture using high-resolution peripheral quantitative computed tomography (HRpQCT) to examine bone strength (ie, failure load) by micro-finite element (µFE) analysis, as well as cortical and trabecular bone parameters at the distal radius and tibia. Level of trauma (mild versus moderate) was assigned using a validated classification scheme, blind to imaging results. When compared to sex-matched, nonfracture controls, women and men with a mild trauma childhood DFF (eg, fall from standing height) had significant reductions in failure load (p < 0.05) of the distal radius, whereas women and men with a moderate trauma childhood DFF (eg, fall while riding a bicycle) had values similar to controls. Consistent findings were observed at the distal tibia. Furthermore, women and men with a mild trauma childhood DFF had significant deficits in distal radius cortical area (p < 0.05), and significantly lower dual-energy X-ray absorptiometry (DXA)-derived bone density at the radius, hip, and total body regions compared to controls (all p < 0.05). By contrast, women and men with a moderate trauma childhood DFF had bone density, structure, and strength that did not differ significantly from controls. These findings in young adults are consistent with our observations in children/adolescents with DFF, and they suggest that a mild trauma childhood DFF may presage suboptimal peak bone density, structure, and strength in young adulthood. Children and adolescents who suffer mild trauma DFFs may need to be targeted for lifestyle interventions to help achieve improved skeletal health.

In patients who have been the victims of high-energy trauma, severe pelvic injury should always be suspected. Most of these fractures are stable and respond well to conservative treatment. Pelvic fractures constitute 3% of all skeletal fractures and are associated with high-energy trauma. They are potentially serious injuries with significant mortality and large numbers of associated lesions. There are fundamentally three sources of bleeding in pelvic fractures: arterial, venous and through the bone ends of the fracture. Arterial bleeding is more associated with hemodynamic instability. In such cases, both early external fixation of the pelvic fracture and angiography with selective embolization of the bleeding vessels are effective methods for achieving hemostasis. Aneurysms of iliac artery branches are rare and are mostly pseudoaneurysm relating to the traumatic event. The natural history of pseudoaneurysms is unknown because of their rarity, but if they rupture, the mortality rate is high. We report a case of spontaneous thrombosis of a pseudoaneurysm of a branch of the right iliac artery. PMID:27026992

Osteoporotic (low-trauma) fractures are a significant public health problem. Over 50% of women over 50yrs. of age will suffer an osteoporotic fracture in their remaining lifetimes. While current therapies reduce skeletal fracture risk by maintaining or increasing bone density, additional information is needed that includes the intrinsic material strength properties of bone tissue to help develop better treatments, since measurements of bone density account for no more than ~50% of fracture risk. The hypothesis tested here is that postmenopausal women who have sustained osteoporotic fractures have reduced bone quality, as indicated with measures of intrinsic material properties compared to those who have not fractured. Transiliac biopsies (N=120) were collected from fracturing (N=60, Cases) and non-fracturing postmenopausal women (N=60, age- and BMD-matched Controls) to measure intrinsic material properties using the nano-indentation technique. Each biopsy specimen was embedded in epoxy resin and then ground, polished and used for the nano-indentation testing. After calibration, multiple indentations were made using quasi-static (hardness, modulus) and dynamic (storage and loss moduli) testing protocols. Multiple indentations allowed the median and variance to be computed for each type of measurement for each specimen. Cases were found to have significantly lower median values for cortical hardness and indentation modulus. In addition, cases showed significantly less within-specimen variability in cortical modulus, cortical hardness, cortical storage modulus and trabecular hardness, and more within-specimen variability in trabecular loss modulus. Multivariate modeling indicated the presence of significant independent mechanical effects of cortical loss modulus, along with variability of cortical storage modulus, cortical loss modulus, and trabecular hardness. These results suggest mechanical heterogeneity of bone tissue may contribute to fracture resistance

Fractures of the transverse processes in the lumbar vertebrae occur as the result of major forces such as direct blunt trauma, violent lateral flexion-extension forces, avulsion of the psoas muscle, or Malgaigne fractures of the pelvis. Dancers make repeated and forceful hyperextension and flexions of the spine, which may cause fractures of the transverse processes of the lumbar vertebrae. Repeated trauma of muscles in dancers may cause avulsion fractures and myositis ossificans. Herein, we report MRI and CT findings of an avulsion from the right transverse process of the L2 and L3 vertebrae in a 16-year-old professional teenage dancer, who responded to conservative treatment.

Background Reflex sympathetic dystrophy (RSD) syndrome is a multifactorial disorder with clinical features of neurogenic inflammation that causes hypersensitivity to pain or severe allodynia as well as blood flow problems, swelling, skin discoloration and maladaptive neuroplasticity due to vasomotor disorders. Patients with major trauma are prone to homeostasis leading to inflammatory response syndrome and multiple organ distress syndrome. Several studies have investigated the etiology of this condition, but the cause remains unknown. The role of associated factors such as the limb immobilization technique and genetics has been reported in the development of this complication, but, so far, there is no information regarding the effect of trauma severity on the risk of RSD occurrence. Objectives Given the importance of diagnosing and treating this condition, we aimed to study the effect of trauma severity on the prevalence of RSD. Patients and Methods In this cross-sectional study, we examined patients with distal tibial fracture who visited Rasht Poursina hospital from 2010 to 2013. Exclusion criteria included associated fractures, underlying musculoskeletal diseases and mental and cognitive problems. To assess the severity of the initial injury in patients, the Hannover Fracture Scale 98 (HFS98) scoring checklist was used. The diagnosis of RSD was made on the basis of the IASP criterion. Demographic data, HFS98 scores, and information regarding RSD prevalence were analyzed using SPSS version 20. The Mann Whitney U nonparametric test was used for variables that were not normally distributed; the chi-square test was used to compare the qualitative variables. Results Among the 488 patients, 292 (59.83%) were male. The mean age of the study population was 44 ± 9.82 years. During the 6-month follow-up, RSD occurred in 45 patients, of whom 28 (62.22%) were female and 17 (37.77%) were male; there was thus a significant difference in the prevalence of RSD in terms of

Traumatic brain and spine injury (TBI/TSI) is a leading cause of death and lifelong disability in children. The biomechanical properties of the child's brain, skull, and spine, the size of the child, the age-specific activity pattern, and variance in trauma mechanisms result in a wide range of age-specific traumas and patterns of brain and spine injuries. A detailed knowledge about the various types of primary and secondary pediatric head and spine injuries is essential to better identify and understand pediatric TBI/TSI, which enhances sensitivity and specificity of diagnosis, will guide therapy, and may give important information about the prognosis. The purposes of this chapter are to: (1) discuss the unique epidemiology, mechanisms, and characteristics of TBI/TSI in children; (2) review the anatomic and functional imaging techniques that can be used to study common and rare pediatric TBI/TSI and their complications; (3) comprehensively review frequent primary and secondary brain injuries; and (4) to give a short overview of two special types of pediatric TBI/TSI: birth-related and nonaccidental injuries.

The objective of this study was to enhance an existing finite element (FE) head model with composite modeling and a new constitutive law for the skull. The response of the state-of-the-art FE head model was validated in the time domain using data from 15 temporo-parietal impact experiments, conducted with postmortem human surrogates. The new model predicted skull fractures observed in these tests. Further, 70 well-documented head trauma cases were reconstructed. The 15 experiments and 70 real-world head trauma cases were combined to derive skull fracture injury risk curves. The skull internal energy was found to be the best candidate to predict skull failure based on an in depth statistical analysis of different mechanical parameters (force, skull internal energy), head kinematic-based parameter, the head injury criterion (HIC), and skull fracture correlate (SFC). The proposed tolerance limit for 50% risk of skull fracture was associated with 453mJ of internal energy. Statistical analyses were extended for individual impact locations (frontal, occipital and temporo-parietal) and separate injury risk curves were obtained. The 50% risk of skull fracture for each location: frontal: 481mJ, occipital: 457mJ, temporo-parietal: 456mJ of skull internal energy.

Otolaryngologists are commonly called upon to emergently evaluate blunt trauma to the facial skeleton. These injuries are occasionally associated with serious trauma to the orbital contents. This manuscript reviews these orbital injuries by considering the pertinent eye anatomy and the extensive examination usually performed by an ophthalmologist. Anterior and posterior segment injuries along with specific trauma to the optic nerve will also be discussed.

Understanding basic ear anatomy and function allows an examiner to quickly and accurately identify at-risk structures in patients with head and ear trauma. External ear trauma (ie, hematoma or laceration) should be promptly treated with appropriate injury-specific techniques. Tympanic membrane injuries have multiple mechanisms and can often be conservatively treated. Temporal bone fractures are a common cause of ear trauma and can be life threatening. Facial nerve injuries and hearing loss can occur in ear trauma.

Differentiation of a recent nasal bone fracture from an old one may become of utmost importance, especially in medico-legal issues. The aim of this study was to demonstrate the value of high-resolution ultrasonography (HRUS) in determining the time of nasal bone fracture. A longitudinal, descriptive-analytic study was done on 45 patients with a clinical manifestation of acute unilateral nasal bone fracture. After a thorough rhinologic physical examination, HRUS was performed by an expert consultant who was blinded to the clinical data of the patients. All patients were followed-up for 6 months: in the first 5 days, 3rd, 6th, 12th and 24th weeks after the trauma. In each session, the ultrasonographic findings were recorded. Thirty-six cases (mean age, 27 years) completed the study course successfully. On HRUS, subperiosteal hematoma, with a mean thickness of 1.14 mm (0.79-1.31 mm) was highly sensitive (100 %) for the diagnosis of nasal bone fracture during the first few days after the trauma, but it was present in 13 cases in the 6th week, with a mean thickness of 0.71 mm (0.62-0.80 mm), and disappeared in all patients in the 24th week, with a mean thickness of 0.47 mm (almost equal to the non-traumatic side). According to the changes of subperiosteal reaction on the traumatic side and by means of generalized linear model and generalized estimating equations, we proposed an equation to estimate the time of nasal bone trauma. In conclusion, HRUS is a reliable diagnostic tool for estimating the time of nasal bone fracture.

Objective To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. Materials and Methods A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Results Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Conclusion Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair. PMID:27587969

Hemorrhagic shock (hS) interacts with the posttraumatic immune response and fracture healing in multiple trauma. Due to the lack of a long-term survival multiple trauma animal models, no standardized analysis of fracture healing referring the impact of multiple trauma on fracture healing was performed. We propose a new long-term survival (21 days) murine multiple trauma model combining hS (microsurgical cannulation of carotid artery, withdrawl of blood and continuously blood pressure measurement), femoral (osteotomy/external fixation) and tibial fracture (3-point bending technique/antegrade nail). The posttraumatic immune response was measured via IL-6, sIL-6R ELISA. The hS was investigated via macrohemodynamics, blood gas analysis, wet-dry lung ration and histologic analysis of the shock organs. We proposed a new murine long-term survival (21 days) multiple trauma model mimicking clinical relevant injury patterns and previously published human posttraumatic immune response. Based on blood gas analysis and histologic analysis of shock organs we characterized and standardized our murine multiple trauma model. Furthermore, we revealed hemorrhagic shock as a causative factor that triggers sIL-6R formation underscoring the fundamental pathophysiologic role of the transsignaling mechanism in multiple trauma.

The charts of 127 consecutive patients who sustained renal trauma between December 1977 and January 1984 were reviewed in order to relate the results of intravenous pyelogram (IVP) to the magnitude of renal pathology. Eighty-eight cases resulted from blunt trauma and 39 cases had penetrating injuries. There were 34 gunshot wounds and five stab wounds. An IVP was performed in 116 patients. All cases of blunt trauma with an IVP reported as normal had no renal pathology greater than contusion. Intravenous pyelogram results in penetrating injuries had a 75% false negative rate. Findings of nonvisualization or extravasation were significant for fractures, perforation, or pedicle injuries in all trauma. Eight of the patients with nonpenetrating wounds and 37 of the patients with penetrating injury underwent exploratory laparotomy. Sixteen nephrectomies were performed for a nephrectomy rate of 12.6% of the total series. This nephrectomy rate is comparable to similar studies which are reviewed.
Background and purpose There have been few prospective studies examining young and middle-aged patients with hip fracture. We therefore investigated background data, risk factors, and the trauma mechanism in young and middle-aged patients with femoral neck fracture. Patients and methods 185 patients, 27 young (20–49 years old) and 158 middle-aged (50–69 years old) were prospectively included in a multicenter study lasting 3 years. Background data and risk factors for osteoporosis and fracture were obtained, and the type of injury was classified as low-energy trauma, high-energy trauma, or sports injury. Results In the young age group, the fracture occurred because of low-energy trauma in two-fifths of patients and because of sport injury in two-fifths of patients. The rest occurred because of high-energy trauma. The corresponding proportions for the middle-aged group were four-fifths, one tenth, and one tenth (p < 0.001). There was a higher proportion of men (19/27) in the young group than in the middle-aged group (69/158) (p = 0.001). One fifth of the young patients were smokers as compared to two-fifths in the middle-age group (p = 0.04). One quarter of the patients reported high-volume alcohol drinking, with no difference between the two groups. Furthermore, three-quarters of the young patients and four-fifths of the middle-aged patients had one or more risk factors for osteoporosis and fracture. Interpretation A minority of patients in each age group had high-energy trauma as the cause of their femoral neck fracture. Lifestyle factors and other non-trauma-related risk factors appear to have been important contributors to the occurrence of femoral neck fracture in both age groups. PMID:23343373

Background Chest CT is more sensitive than a chest X-ray (CXR) in diagnosing rib fractures; however, the clinical significance of these fractures remains unclear. Objectives The purpose of this study was to determine the added diagnostic use of chest CT performed after CXR in patients with either known or suspected rib fractures secondary to blunt trauma. Methods Retrospective cohort study of blunt trauma patients with rib fractures at a level I trauma center that had both a CXR and a CT chest. The CT finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on CXR was considered clinically meaningful. Student’s t-test and chi-square analysis were used for comparison. Results We identified 499 patients with rib fractures: 93 (18.6%) had CXR only, 7 (1.4%) had chest CT only, and 399 (79.9%) had both CXR and chest CT. Among these 399 patients, a total of 1,969 rib fractures were identified: 1,467 (74.5%) were missed by CXR. The median number of additional fractures identified by CT was 3 (range, 4 - 15). Of 212 (53.1%) patients with a clinically meaningful increase in the number of fractures, 68 patients underwent one or more clinical interventions: 36 SICU admissions, 20 pain catheter placements, 23 epidural placements, and 3 SSRF. Additionally, 70 patients had a chest tube placed for retained hemothorax or occult pneumothorax. Overall, 138 patients (34.5%) had a change in clinical management based upon CT chest. Conclusions The chest X-ray missed ~75% of rib fractures seen on chest CT. Although patients with a clinical meaningful increase in the number of rib fractures were more likely to be admitted to the intensive care unit, there was no associated improvement in pulmonary outcomes.

Blunt traumatic abdominal wall disruptions associated with evisceration are very rare. The authors describe a case of traumatic abdominal wall disruption with bowel evisceration that occurred after a middle-aged woman sustained direct focal blunt force impact to the lower abdomen. Abdominal exploration and surgical repair of the abdominal wall defect were performed, with good clinical outcome. A brief overview of literature pertinent to this rare trauma scenario is presented.

Background In September 2011, Kingston General Hospital (KGH) opened a dedicated orthopedic weekend trauma room. Previously, 1 weekend operating room (OR) was used by all surgical services. We assessed the impact this dedicated weekend trauma room had on hospital length of stay (LOS), time to surgery and 30-day mortality for patients with hip fractures. Methods Patients admitted between Oct. 1, 2009, and Sept. 30, 2012, were identified through our trauma registry, representing the 2 years before and 1 year after the opening of the orthopedic weekend trauma room. We documented type of fracture, mode of fixation, age, sex, American Society of Anesthesiologists (ASA) score, time to OR, LOS, discharge disposition and 30-day mortality. We excluded patients with multiple fractures, open fractures and those requiring trauma team activation. Results Our study included 609 patients (405 pre- and 204 post–trauma room opening). Mean LOS decreased from 11.6 to 9.4 days (p = 0.005) and there was a decreasing trend in mean time to OR from 31.5 to 28.5 hours (p = 0.16). There was no difference in 30-day mortality (p = 0.24). The LOS decreased by an average of 2 days following opening of the weekend trauma room (p = 0.031) and by an average of 2.2 additional days if the patient was admitted on the weekend versus during the week (p = 0.024). Conclusion The weekend trauma OR at KGH significantly decreased the LOS and appears to have decreased wait times to surgery. Further analysis is needed to assess the cost-effectiveness of the current strategy, the long-term outcome of this patient population and the impact the additional orthopedic weekend trauma room has had on other surgical services (i.e., general surgery) and their patients.

This study's objective was to identify clinical characteristics of patients with a blunt traumatic injury that increased the risk of peritoneal or pericardial fluid collections and abdominal organ injuries not identified by a bedside focused abdominal sonogram for trauma (FAST) examination. This observational study used a retrospective chart review of a cohort of patients identified through a query of the University of Nebraska Medical Center's trauma registry, a tertiary referral center for portions of Nebraska, Iowa, and Missouri. Adult patients presenting to the Emergency Department (ED) for an evaluation of blunt traumatic injury from September 1996 to December 2002 were eligible if their ED course included admission to the trauma service after completion of a bedside FAST examination (US) and a confirmatory study (Conf) such as an abdominopelvic computed tomography scan or exploratory laparotomy within 12 h of completion of the ED FAST examination. The medical records of those patients with a US+/Conf+ or US-/Conf+ examination were reviewed. Clinical characteristics were recorded on a standard data collection form. Statistically significant predictors of a US-/Conf+ examination were found using a stepwise logistic regression procedure. A query of the trauma registry for the study period revealed 1453 adult individuals with blunt abdominal trauma, with 458 patients meeting the inclusion criteria. The clinical characteristics of the 79 US+/Conf+ examinations were compared to those of the 53 US-/Conf+ examinations. The presence of a radiographically proven pelvic fracture (odds ratio 3.459; 95% confidence interval of 1.308-9.157) and a radiographically or operatively proven renal injury (odds ratio 3.667; 95% confidence interval of 1.013-13.275) were found to be significant predictors. The presence of a pelvic fracture or renal injury in adult victims of blunt abdominal trauma increases the likelihood of a US-/Conf+ examination. Patients with a negative FAST

Background This study uses the American College of Surgeons National Trauma Data Bank (NTDB) to update the field on the demographics, injury mechanisms, and concurrent injuries among a national sample of patients admitted to the hospital department with calcaneus fractures. Methods Patients with calcaneus fractures in the NTDB during 2011-2012 were identified and assessed. Results A total of 14 516 patients with calcaneus fractures were included. The most common comorbidity was hypertension (18%), and more than 90% of fractures occurred via traffic accident (49%) or fall (43%). A total of 11 137 patients had concurrent injuries. Associated lower extremity fractures had the highest incidence and occurred in 61% of patients (of which the most common were other foot and ankle fractures). Concurrent spine fractures occurred in 23% of patients (of which the most common were lumbar spine fractures). Concurrent nonorthopaedic injuries included head injuries in 18% of patients and thoracic organ injuries in 15% of patients. Conclusion This national sample indicates that associated injuries occur in more than three quarters calcaneus fracture patients. The most common associated fractures are in close proximity to the calcaneus. Although the well-defined association of calcaneus fractures with lumbar spine fractures was identified, the data presented highlight additional strong associations of calcaneus fractures with other orthopaedic and nonorthopaedic injuries.

Background Isolated sternal fractures (SFs) rarely show complications, but their influence in a thorax trauma of the seriously injured still remains unclear. Methods A retrospective analysis of the TraumaRegister DGU(®) was performed involving the years 2009 to 2013 (Injury Severity Score [ISS] ≥ 16, primary admission to a trauma center). Cohort formation: Unilateral and bilateral flail chest (FC) injuries with and without a concomitant SF, respectively. Results In total, 21,741 patients (25% female) met the inclusion criteria, with 3,492 (16.1%) showing SF. Unilateral FC patients were on average 53.6 ± 18.4 years old, and bilateral FC patients were on average 55.2 ± 17.7 years old. The ISS in unilateral FC and bilateral FC amounted to 31.2 ± 13.0 and 43.4 ± 13.1 points, respectively. FC with an SF occurred more frequently as an injury to car occupants and less frequently as an injury to motorcyclists or in injuries due to falls. Conclusion Patients with an SF additional to an FC had longer hospital and intensive care unit stays and were longer artificially respirated than those patients without an SF. SF indicates possible cardiac and thoracic spine injuries.

Fractures in bones of the skull base (BSB) are preconditioned by the contact zone of interaction between the two below surfaces, i.e. the trace-forming one (object) and the trace-receiving one (bone). On the basis of their independent research, the authors suggest a set of criteria for the expert evaluation of fractures in BSB for the purpose of specifying the properties of the trauma-causing object, which is made with due regard for the anatomic specific features of the trauma zone.

The field of forensic injury biomechanics is an emerging field. Biomechanically validated tools may assist interdisciplinary teams of investigators in assessing mechanisms of blunt head trauma resulting in skull fractures. The objective of this study is to assess the biofidelity of spherical, frangible skull-brain (SB) surrogates. Blunt impacts were conducted at 20 m/s, using an instrumented 103 g rigid impactor, to the temporo-parietal region of four defleshed cephalic postmortem human subjects (PMHS). Force-deformation response, fracture tolerance, and fracture patterns were recorded for comparison to spherical skull-brain surrogates. Three brain substitutes were assessed: 10% gelatin, lead shot with Styrofoam and water. Force-deformation response of the skull-brain surrogates was similar to defleshed PMHS up to the point of fracture; however, none of the surrogates fractured at tolerance levels comparable to the PMHS. Fracture patterns of the skull-brain surrogates were linear and radiating, while PMHS fractures were all depressed, comminuted.

Background and aim This study aims at evaluating the reliability on specific multi-planar cone beam computer tomography (CBCT) reconstruction in the orbital floor fractures. Methods CBCT examination of the mid-face fractures area involving the floor of the orbit was performed in a number of 93 trauma patients by two independent radiologists. Both radiologists assessed the axial, coronal and sagittal sections and also the oblique coronal and sagittal extracted sections evaluating the location of the orbital fractures, its size and displacement, the involvement of the infra-orbital foramen, herniation of fat or muscle within the maxillary sinus, the overall type of the fracture and the implication of lateral or medial orbital wall. We also registered the section that provided better confidence of both examiners in visualizing the fracture of the orbit floor and the presence of herniated soft tissue, on different reformatted sectioning. Results The presence of pure fracture of the orbital floor was detected in 11% of patients. The association of the orbital fractures with the zygomatic fractures was identified in the majority of the patients. In 86% of patients the displacement of the floor of the orbit was visualized, and in almost 30% of cases more than 50% of the orbital floor was involved in the fracture. Regarding the confidence between examiners, they were more confident using the oblique sagittal CBCT reformatted images for fracture detection and bone displacement evaluation, as for the soft tissue herniation the oblique coronal sections provided the highest level of confidence. Conclusion Mid-face trauma involves the orbital floor in the majority of situations. CBCT allows to obtain oblique images extracted from the three dimensional (3D) data that provide high confidence level in assessing pure orbital floor fractures. PMID:27857522

The purpose of this trial was to compare National Emergency X-Radiography Utilization Study (NEXUS) criteria (NC) with computed tomography (CT) as the gold standard to evaluate cervical spine (C-spine) fractures in elderly blunt trauma patients. We prospectively compared adult blunt trauma patients 65 years or older (E) with younger than 65 years (NE), evaluating the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of NC compared with CT in these two cohorts. A total of 2785 blunt trauma patients were included of whom 320 were E (average age, 75 years) and 2465 were NE (average age, 36 years). Incidence of C-spine fracture was 12.8 per cent (E) versus 7.4 per cent (NE) (P = 0.002). Age was an independent predictor of fracture (P = 0.01). NC had a sensitivity of 65.9 per cent in E and PPV of 19.3 per cent in E (P = 0.001) versus a sensitivity of 84.2 per cent in NE and PPV of 10.6 per cent (P < 0.0001). The specificity was 59.5 per cent for E versus 42.6 per cent for NE (NPV, 92.2% E vs 97.1% NE). This study suggests that NEXUS criteria are not an appropriate assessment tool when applied to severe blunt trauma patients, particularly in the elderly population who had more missed injures than their younger counterparts. CT should be used in all blunt trauma patients regardless of whether they meet NEXUS criteria.

Abdominal trauma accounts for nearly 20% of all severe traffic injuries and can often result from intentional physical violence, from which blunt liver injury is regarded as the most common result and is associated with a high mortality rate. Liver injury may be caused by a direct impact with a certain velocity and energy on the abdomen, which may result in a lacerated liver by penetration of fractured ribs. However, liver ruptures without rib cage fractures were found in autopsies in a series of cases. All the victims sustained punches on the abdomen by fist. Many studies have been dedicated to determining the mechanism underlying hepatic injury following abdominal trauma, but most have been empirical. The actual process and biomechanism of liver injury induced by blunt impact on the abdomen, especially with intact ribs remained, are still inexhaustive. In order to investigate this, finite element methods and numerical simulation technology were used. A finite element human torso model was developed from high resolution CT data. The model consists of geometrically-detailed liver and rib cage models and simplified models of soft tissues, thoracic and abdominal organs. Then, the torso model was used in simulations in which the right hypochondrium was punched by a fist from the frontal, lateral, and rear directions, and in each direction with several impact velocities. Overall, the results showed that liver rupture was primarily caused by a direct strike of the ribs induced by blunt impact to the abdomen. Among three impact directions, a lateral impact was most likely to cause liver injury with a minimum punch speed of 5 m/s (the momentum was about 2.447 kg.m/s). Liver injuries could occur in isolation and were not accompanied by rib fractures due to different material characteristics and injury tolerance.

Klippel-Feil syndrome (KPS) is a congenital spinal deformity characterised by the presence of at least one fused cervical segment. We report an unusual case of a fracture through fused cervical segment in a patient with KPS, who presented with quadriparesis and progressed on to develop respiratory failure and quadriplegia and who had a successful outcome following surgery. To the best of our knowledge, fracture through fused cervical segments in a Klippel-Feil patient has not been reported previously and this case report extends the spectrum of injuries seen in patients with KPS.

Introduction Traumatic injury is a leading cause of death and disability in adults ≥ 65 years old, but there are few epidemiological studies addressing this issue. The aim of this study was to assess how characteristics of blunt traumatic injuries in adults ≥ 65 vary by age. Methods Using data from the a single-state trauma registry, this retrospective cohort study examined injured patients ≥ 65 admitted to all Level I and Level II trauma centers in Pennsylvania between 2011 and 2014 (n=38,562). Patients were stratified by age into three subgroups (age 65–74; 75–84; ≥85). We compared demographics, injury, and system-level across groups. Results We found significant increases in the proportion of female gender, (48.6% vs. 58.7% vs. 67.7%), white race (89.1% vs. 92.6% vs. 94.6%), and non-Hispanic ethnicity (97.5% vs. 98.6% vs. 99.4%) across advancing age across age groups, respectively. As age increased, the proportion of falls (69.9% vs. 82.1% vs. 90.3%), in-hospital mortality (4.6% vs. 6.2% vs. 6.8%), and proportion of patients arriving to the hospital via ambulance also increased (73.6% vs. 75.8% vs. 81.1%), while median injury severity plateaued (9.0% all groups) and the proportion of Level I trauma alerts (10.6% vs. 8.2% vs. 6.7%) decreased. We found no trend between age and patient transfer status. The five most common diagnoses were vertebral fracture, rib fracture, head contusion, open head wound, and intracranial hemorrhage, with vertebral fracture and head contusion increasing with age, and rib fracture decreasing with age. Conclusion In a large cohort of older adults with trauma (n= 38,000), we found, with advancing age, a decrease in trauma alert level, despite an increase in mortality and a decrease in demographic diversity. This descriptive study provides a framework for future research on the relationship between age and blunt traumatic injury in older adults. PMID:27833676

OBJECTIVE Blunt cerebrovascular injuries (BCVIs) affect approximately 1% of patients with blunt trauma. An antithrombotic or anticoagulation therapy is recommended to prevent the occurrence or recurrence of neurovascular events. This treatment has to be carefully considered after severe traumatic brain injury (TBI), due to the risk of intracranial hemorrhage expansion. Thus, the physician in charge of the patient is confronted with a hemorrhagic and ischemic risk. The main objective of this study was to determine the incidence of BCVI after severe TBI. METHODS The authors conducted a prospective, observational, single-center study including all patients with severe TBI admitted in the trauma center. Diagnosis of BCVI was performed using a 64-channel multidetector CT. Characteristics of the patients, CT scan results, and outcomes were collected. A multivariate logistic regression model was developed to determine the risk factors of BCVI. Patients in whom BCVI was diagnosed were treated with systemic anticoagulation. RESULTS In total, 228 patients with severe TBI who were treated over a period of 7 years were included. The incidence of BCVI was 9.2%. The main risk factors were as follows: motorcycle crash (OR 8.2, 95% CI 1.9-34.8), fracture involving the carotid canal (OR 11.7, 95% CI 1.7-80.9), cervical spine injury (OR 13.5, 95% CI 3.1-59.4), thoracic trauma (OR 7.3, 95% CI 1.1-51.2), and hepatic lesion (OR 13.3, 95% CI 2.1-84.5). Among survivors, 82% of patients with BCVI received systemic anticoagulation therapy, beginning at a median of Day 1.5. The overall stroke rate was 19%. One patient had an intracranial hemorrhagic complication. CONCLUSIONS Blunt cerebrovascular injuries are frequent after severe TBI (incidence 9.2%). The main risk factors are high-velocity lesions and injuries near cervical arteries.

A 62-year-old male was admitted after being struck by a bus. He sustained a severe pelvic fracture, sigmoid colon injury, and both intraperitoneal and extraperitoneal bladder injury. He underwent initial successful bladder repair. However, at 7 days post-operatively he manifested a leak from the repair and urine was evident coming from the pins of his pelvic external fixator. A repeat cystogram showed massive extravasation, which was managed by operative ligation of the lower ureters and placement of percutaneous nephrostomy tubes. He underwent ureteral reconstruction and colostomy reversal at 9 months. He has both bladder and bowel control. PMID:26793492

We report a case of thoracic aortic rupture after blunt trauma in a 23-year-old male patient. The initial investigation found no external injury or bleeding, only a slightly widened mediastinum and a broken left calcaneus. Abdominal lavage was negative, biochemistry was normal, and breathing and oxygenation were not compromised. When changing his position during diagnostics, the patient all of a sudden developed cardiac arrest and typical signs of hypovolemic shock. An immediate sternotomy was done without any further diagnostics on suspicion of aortic isthmus injury. A circular avulsion at the ligamentum arteriosum was found as assumed and repaired under cardiopulmonary bypass. The patient left the hospital for rehabilitation after 12 days in adequate health status. Biodynamics of blunt trauma after high-speed frontal impact and the relationship between calcaneus fracture, called "Don-Juan fracture," and aortic rupture at the site of ligamentum arteriosum are discussed.

Diaphragmatic injury is an uncommon but clinically important entity in the setting of trauma. Computed tomography (CT) is widely used to evaluate hemodynamically stable trauma patients. While prior studies have identified CT signs of diaphragm injury in blunt or penetrating trauma, no study has directly compared signs across these two types of injuries. We identified patients with surgically proven diaphragm injuries who underwent CT at presentation. Three reviewers examined each for 12 signs of diaphragm injury, as well as for an overall impression of diaphragm injury. We reviewed a total of 84 patients (37 % blunt trauma, 63 % penetrating). The initial interpreting radiologists discovered 77 % of blunt and 47 % of penetrating injuries (p = 0.01). We found that the majority of signs of diaphragmatic injury were split between those common in blunt trauma and those common in penetrating trauma, with minimal overlap. The presence of at least one blunt injury sign has 90 % sensitivity for diaphragm injury in blunt trauma; the presence of a wound tract traversing the diaphragm has 92 % sensitivity in penetrating trauma. Inter-observer reliability of these signs is also high (κ > 0.65). Penetrating diaphragm injuries present a different spectrum of imaging findings from those in blunt trauma and are underdiagnosed at CT; looking for a wound tract traversing the diaphragm is highly sensitive for diaphragm injury in these cases. Signs of organ or diaphragm fragment displacement are sensitive for blunt diaphragm injuries, consistent with these injuries being caused by increased intra-abdominal pressure.

Of 161 patients with blunt thoracic injury, 135 were male (83.9%) and 26 were female. The most common cause of injury was traffic accidents (130 patients, 80.7%), followed by falls (22 patients), and crushing (7 patients). There were 46 third decade and 36 second decade patients. Thirty-two patients had single thoracic injury and the other had multiple organ injury. The most common associated injury was head injury (65 patients). Most traffic accidents involved motor cycle accident. Forty-four patients died, 32 within 24 hours, and 4 died to thoracic injury. These 4 patients were shock on arrival and died within 24 hours. The injury severity score, which was under 30 in 78.3% of patients, correlated to the mortality rate. Rib fracture was the most common thoracic injury in 96 patients followed by hemothorax in 91, pulmonary contusion in 79, and pneumothorax in 64. Most of the thoracic injuries were treated conservatively. Thoracotomy was performed in 6 patients. Other than one patient with rupture of the left pulmonary vein, 5 patients recovered. Continued bleeding at a rate of more than 200 ml/h from the chest drainage tube or no recovery from shock and large air leakage preventing re-expansion of the lung are indications for emergency thoracotomy. Thoracotomy should also be considered after conservative treatment in patients with continued air leakage or intrabronchial bleeding negatively affecting respiration. Indications for thoracotomy should be determined individually based on evaluating of vital sign.

A 28-year-old man was brought to the emergency department for severe facial swelling the morning after a bungee jumping accident. The patient had been making jumps nearly every weekend for the past 3 years without injury. This time, he had performed a nighttime jump from a railroad trestle over the gorge of a small river. The height of the bridge at the center of the gorge was about 200 ft, and the river was about 12 ft deep. When the patient jumped, he hit the water face first, plunging under the surface to his waist. The cause of the accident was thought to be a miscalculation of the bridge height.

Previous studies have indicated that metal particles remain on bone after sharp force injury or gunshot and that their detection by scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS) could greatly help in tool identification. However, the presence of metal particles on bone surfaces in the context of blunt force trauma has never been assessed experimentally. For this reason the present paper represents an experimental study of the behaviour of metal residues on bone following blunt force injury. Ten fresh sub-adult bovine metatarsal bones were manually cleaned of soft tissues. They were then struck by metal bars (copper, iron or aluminium) on the external surface of the mid-diaphysis. All blunt metal instruments used in this study left a sign in the form of single particles, a smear or a powder-like deposit on the bone surface. The residues of all three metal implements were detected on the bone surface, 0.3-10 mm from the fracture border. The presence of metal particles was confirmed in all samples struck with iron and copper and in two of six aluminium samples; no particles were detected on the negative control. Chemical composition of residues highly corresponded with the composition of applied bars.

The diagnosis of “penile fracture” describes the traumatic rupture of the tunica albuginea of an erect penis. Penile fractures typically occur when the engorged penile corpora are forced to buckle and literally “pop” under the pressure of a blunt sexual trauma. Patients typically describe immediate detumescence, severe pain, and swelling as a result of the injury. Prompt surgical exploration and corporal repair is the most efficacious therapy. Although a majority of cases can be diagnosed from the history and physical examination alone, radiographic studies, including retrograde urethrography and corporal cavernosography can aid in the diagnosis of unusual cases.

When performing a radiological assessment for a trauma case with associated head injury, a fragment of dense tissue detected near the craniovertebral junction would rapidly be assessed as a fractured bone fragment. However, if further imaging and evaluation of the cervical spine with computerised tomography (CT) did not demonstrate an obvious fracture, then the possibility of ligament calcification would be considered. We present a case involving a previously healthy 44-yearold man who was admitted following a severe head injury from a road traffic accident. CT scans of the head showed multiple intracranial haemorrhages, while scans of the cervical spine revealed a small, well-defined, ovoid calcification in the right alar ligament. This was initially thought to be a fracture fragment. Although such calcification is uncommon, accident and emergency physicians and radiologists may find this useful as a differential diagnosis in patients presenting with neck pain or traumatic head injury.

Pneumomediastinum is often an incidental finding following a blunt or penetrating trauma to the neck or chest. We report a rare case of pneumomediastinum following an isolated facial trauma that was diagnosed on imaging. We also review the clinical signs of this condition, its radiologic characteristics, and the 18 previously reported cases of pneumomediastinum following facial trauma.

Background Coronary artery dissection is a rare complication of blunt thoracic trauma which can become rapidly lethal necessitating prompt diagnosis and treatment. Most reported cases of coronary artery injury, including dissection, involve the left anterior descending coronary artery, given its anatomical location in relation to the impact. Description of case A 72-year-old male, who was involved in a vehicular accident, sustained blunt thoracic trauma which resulted in isolated right coronary artery dissection and acute myocardial infarction. The culprit lesion was found in coronary angiography in the proximal right coronary artery and was successfully repaired with percutaneous coronary intervention and one drug-eluting stent placement. Conclusion Traumatic dissection of coronary arteries must be suspected in blunt thoracic trauma. It can be treated with interventional management and results in a fairly good prognosis.

INTRODUCTION Blunt esophageal injury is extremely rare event. However, it is a potential morbid injury unless managed early. PRESENTATION OF CASE We report a rare case of blunt esophageal injury for a 28-year old male who presented with history of fall of heavy object over the right side of the chest. Diagnostic work up including chest X-ray, computerized tomography scans and gastrografin esophagogram revealed lower esophageal rupture. Right mini-thoracotomy with esophageal repair was performed. Postoperative course was uneventful. DISCUSSION The exact mechanism of blunt esophageal injury remains uncertain. This report described a unique location of esophageal rupture after blunt trauma that happened on the right side. Diagnosis of esophageal injury needs high index of suspicion and accurate diagnostic workup. CONCLUSION Prompt diagnosis and management are the key for better prognosis in patients with blunt esophageal injury. PMID:24394856

Bone has one of the highest acoustic densities (AD) in the human body. Traditionally, bone has been considered to be a hindrance to the use of ultrasound (US), as US waves are reflected by the dense matrix and obscure underlying structures. The intense wave reflection, however, can clearly illustrate the cortical bony anatomy of long bones, making cortical disruption obvious. Ultrasound can be used at the bedside concurrently with the overall trauma resuscitation, and may potentially limit the patient's and treating team's exposure to ionizing radiation, corroborate clinical findings, and augment procedural success. The extended focused assessment with sonography for trauma (EFAST) is an essential tool in the resuscitation of severe torso trauma, frequently demonstrating intra- pericardial and intra-peritoneal fluid, inferring hemo/pneumothoraces, and demonstrating cardiac function. Although it is typically considered as a diagnosis of exclusion, multiple long-bone fractures may be a source of shock and can be quickly confirmed at the bedside with EFAST. Further, the early detection of long-bone fractures can also aid in the early stabilization of severely injured patients. Sonographic evaluation for long-bone fractures may be particularly useful in austere environments where other imaging modalities are limited, such as in the battlefield, developing world, and space. While prospective study has been limited, selected series have demonstrated high accuracy among both physician and para-medical clinicians in detecting long-bone fractures. Pitfalls in this technique include reduced accuracy with the small bones of the hands and feet, as well as great reliance on user experience.

Background Previous research has shown that dietary patterns are related to the risk of several adverse health outcomes, but the relation of these patterns to skeletal fragility is not well understood. Objective Our objective was to determine the relation between dietary patterns and incident fracture and possible mediation of this relation by body mass index, bone mineral density, or falls. Design We performed a retrospective cohort study based on the Canadian Multicentre Osteoporosis Study—a randomly selected population-based cohort. We assessed dietary patterns by using self-administered food-frequency questionnaires in year 2 of the study (1997–1999). Our primary outcome was low-trauma fracture occurring before the 10th annual follow-up (2005–2007). Results We identified 2 dietary patterns by using factor analysis. The first factor (nutrient dense) was strongly associated with intake of fruit, vegetables, and whole grains. The second factor (energy dense) was strongly associated with intake of soft drinks, potato chips, French fries, meats, and desserts. The nutrient-dense factor was associated with a reduced risk of fracture per 1 SD in men overall [hazard ratio (HR): 0.83; 95% CI: 0.64, 1.08] and in women overall (HR: 0.86; 95% CI: 0.76, 0.98). An age trend (P = 0.03) was observed, which yielded an HR of 0.97 in younger women (age <70 y) compared with an HR of 0.82 in older women (age ≥70 y). The associations were independent of body mass index, bone mineral density, falls, and demographic variables. The energy-dense pattern was not related to fracture. Conclusion A diet high in vegetables, fruit, and whole grains may reduce the risk of low-trauma fracture, particularly in older women. PMID:21068350

Coronary artery dissection and aneurysm culminating in acute myocardial infarction are rare after blunt chest trauma. We are reporting a case of a previously healthy 52-year-old man who presented with right inferior lobe contusion, pleural effusion, right interlobar fissure effusion, bone fracture of right fourth rib, and acute inferior wall myocardial infarction and who experienced blunt trauma in his right chest wall by an airbag deployment in a car accident. Coronary angiography showed an aneurysm in the middle of right coronary artery with 70% afferent narrowing just distal to the aneurysm with no visible atherosclerotic lesion. A 4.0×20 mm TEXUS Liberté stent in the lesion was deployed, and a good coronary flow was obtained without residual stenosis and the aneurysm vanished.

Pelvic ring fractures are defined as life-threatening injuries that can be treated surgically with external or internal fixation. The authors report on an 81-year-old woman with an unstable pelvic fracture accompanying multiple traumas that was successfully treated with a less invasive procedure. The patient was injured in a traffic accident and sustained a total of 20 fractures, including pelvic ring, bilateral rib, and lumbar transverse processes fractures, and multiple fractures of both upper and lower extremities. The pelvic ring fracture was unstable with fractures of the bilateral sacrum with right sacroiliac disruption, right superior and inferior pubic rami, left superior pubic ramus, and ischium. During emergency surgery, bilateral external fixation was applied to the iliac crest to stabilize the pelvic ring. Second and third surgeries were performed 11 and 18 days after the first emergency surgery, respectively, to treat the multiple fractures. At the third surgery, the pelvic ring fracture was stabilized surgically using a less invasive posterior fixation technique. In this technique, 2 iliac screws were inserted on each side following an 8-cm midline posterior incision from the S-1 to S-3 spinous process, with the subcutaneous tissue detached from the fascia of the paraspinal muscles. The S-2 spinous process was removed and 2 rods were connected to bilateral iliac screws to stabilize the bilateral ilium in a switchback fashion. A crosslink device was applied to connect the 2 rods at the base of the S-2 spinous process. Following pelvic fixation, percutaneous pedicle screws were inserted into L-4 and L-5 vertebral bodies on both sides, and connected to the cranial rod connecting the bilateral iliac screws, thus completing the lumbopelvic fixation. The postoperative course was favorable with no postoperative complications. At the 10-month follow-up, bone union had been achieved at the superior ramus of the pubis, the patient did not complain of pain, and

Pelvic trauma accounts for only 3% of all skeletal injuries but may have mortality as high as 45% in cases of severe trauma. Significant high-grade-mechanism trauma to the pelvis must always take the abdomen into consideration for evaluation. The focused assessment with sonography for trauma (FAST) examination has been shown to be a valuable tool in assessing the unstable trauma patient with blunt abdominal injury, though its diagnostic utility is much less well-defined than in primary pelvic trauma. This systematic review explores the utility and limitations of the FAST examination in patients with blunt pelvic trauma and discusses the timing for the examination during the trauma survey. Newer techniques for emergency department management of the unstable trauma patient are also addressed.

With increased awareness and liberal screening of trauma patients with identified risk factors, recent case series demonstrate improved early diagnosis of carotid artery trauma before they become problematio. There remains a need for unified screening criteria for both intracranial and extracranial carotid trauma. In the absence of contraindications, antithrombotic agents should be considered in blunt carotid artery injuries, as there is a significant risk of progression of vessel injury with observation alone. Despite CTA being used as a common screening modality, it appears to lack sufficient sensitivity. DSA remains to be the gold standard in screening. Endovascular techniques are becoming more widely accepted as the primary surgical modality in the treatment of blunt extracranial carotid injuries and penetrating/blunt intracranial carotid lessions. Nonetheless, open surgical approaches are still needed for the treatment of penetrating extracranial carotid injuries and in patients with unfavorable lesions for endovascular intervention.

The distinction between perimortem and postmortem fractures is an important challenge for forensic anthropology. Such a crucial task is presently based on macro-morphological criteria widely accepted in the scientific community. However, several limits affect these parameters which have not yet been investigated thoroughly. This study aims at highlighting the pitfalls and errors in evaluating perimortem or postmortem fractures. Two trained forensic anthropologists were asked to classify 210 fractures of known origin in four skeletons (three victims of blunt force trauma and one natural death) as perimortem, postmortem, or dubious, twice in 6 months in order to assess intraobserver error also. Results show large errors, ranging from 14.8 to 37% for perimortem fractures and from 5.5 to 14.8% for postmortem ones; more than 80% of errors concerned trabecular bone. This supports the need for more objective and reliable criteria for a correct assessment of peri- and postmortem bone fractures.

Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations. Pneumothorax can also be quickly detected with ultrasound. During the secondary survey and in patients sustaining low-speed or localized trauma, ultrasound can be used to help detect abdominal organ injuries. This is particularly helpful in patients in whom hemoperitoneum is not identified on an initial scan because findings of organ injuries will expedite the next test, often computed tomography (CT). Moreover, ultrasound can assist in detection of fractures easily obscured on radiography, such as rib and sternal fractures.

We present a case report of a college baseball player who sustained a blunt-trauma, distal-third ulna fracture from a thrown ball with delayed presentation of ulnar nerve palsy. Even after his ulna fracture had healed, the nerve injury made it difficult for the athlete to control a baseball while throwing, resulting in a delayed return to full baseball activity for 3 to 4 months. He had almost complete nerve recovery by 6 months after his injury and complete nerve recovery by 1 year after his injury.

Introduction : The nonoperative management of traumatic spleen injuries is the modality of choice in patients with blunt abdominal trauma and hemodynamic stability. However, there are still questions about the treatment indication in some groups of patients, as well as its follow-up. Aim: Update knowledge about the spleen injury. Method : Was performed review of the literature on the nonoperative management of blunt injuries of the spleen in databases: Cochrane Library, Medline and SciELO. Were evaluated articles in English and Portuguese, between 1955 and 2014, using the headings "splenic injury, nonoperative management and blunt abdominal trauma". Results : Were selected 35 articles. Most of them were recommendation grade B and C. Conclusion : The spleen traumatic injuries are frequent and its nonoperative management is a worldwide trend. The available literature does not explain all aspects on treatment. The authors developed a systematization of care based on the best available scientific evidence to better treat this condition.

The aim of this study was to investigate the characteristics of unilateral tibial plateau fractures among hospitalized adult patients in Xijing Hospital, to evaluate the accuracy of Schatzker classification system and AO/OTA classification system to tibial plateau fractures. We retrospectively analysed clinical data on 274 patients admitted to Xijing Hospital between September 2006 and August 2015. The patients’ demographic characteristics, admission periods and seasons, external causes and fracture types were recorded and summarized. Then the characteristics of tibial plateau fractures and the accuracy rate of these two classification systems were analysed. Schatzker type II fractures and AO/OTA type 41-B3 fractures were the most common types. The external causes differed between genders, types of employment, urban-rural residents and both two systems. In addition, some fractures were difficult to classify using Schatzker or AO/OTA classification system. Rural male physical labourers aged between 30–59 years-old were most likely to suffer from unilateral tibial plateau fractures, due to traffic accidents, falls and indoor activity injuries, or falls from height. We should pay more attention to the related people and professions, which contributed to the high occurrence of tibial plateau fractures. Besides that, further improvements are required for both Schatzker and AO/OTA classification systems. PMID:28074894

Introduction. Labyrinthine concussion is a term used to describe a rare cause of sensorineural hearing loss with or without vestibular symptoms occurring after head trauma. Isolated damage to the inner ear without involving the vestibular organ would be designated as a cochlear labyrinthine concussion. Hearing loss is not a rare finding in head trauma that involves petrous bone fractures. Nevertheless it generally occurs ipsilateral to the side of the head injury and extraordinarily in the contralateral side and moreover without the presence of a fracture. Case Report. The present case describes a 37-year-old patient with sensorineural hearing loss and tinnitus in his right ear after a blunt head trauma of the left-sided temporal bone (contralateral). Otoscopy and radiological images showed no fractures or any abnormalities. A severe sensorineural hearing loss was found in his right ear with a normal hearing of the left side. Conclusion. The temporal bone trauma requires a complete diagnostic battery which includes a neurotologic examination and a high resolution computed tomography scan in the first place. Hearing loss after a head injury extraordinarily occurs in the contralateral side of the trauma as what happened in our case. In addition, the absence of fractures makes this phenomenon even more unusual. PMID:27738540

Background: A cross-sectional study to investigate the association of Osteoporosis Self-Assessment Tool for Asians (OSTA) score with clinical presentation and expenditure of hospitalized adult trauma patients with femoral fractures. Methods: According to the data retrieved from the Trauma Registry System between 1 January 2009 and 31 December 2015, a total of 2086 patients aged ≥40 years and hospitalized for treatment of traumatic femoral bone fracture were categorized as high-risk patients (OSTA < −4, n = 814), medium-risk patients (−1 ≥ OSTA ≥ −4, n = 634), and low-risk patients (OSTA > −1, n = 638). Two-sided Pearson’s, chi-squared, or Fisher’s exact tests were used to compare categorical data. Unpaired Student’s t-test and Mann-Whitney U-test were used to analyze normally and non-normally distributed continuous data, respectively. Propensity-score matching in a 1:1 ratio was performed using Number Crunching Statistical Software (NCSS) software (NCSS 10; NCSS Statistical Software, Kaysville, UT, USA), with adjusted covariates including mechanism and Glasgow Coma Scale (GCS); injuries were assessed based on the Abbreviated Injury Scale (AIS), and Injury Severity Score (ISS) was used to evaluate the effect of OSTA-related grouping on a patient’s outcome. Results: High-risk and medium-risk patients were predominantly female, presented with significantly older age and higher incidences of co-morbidity, and were injured in a fall accident more frequently than low-risk patients. High-risk patients and medium-risk patients had a different pattern of femoral fracture and a significantly lower ISS. Although high-risk and medium-risk patients had significantly shorter lengths hospital of stay (LOS) and less total expenditure than low-risk patients did, similar results were not found in the selected propensity score-matched patients, implying that the difference may be attributed to the associated injury severity of the patients with femoral fracture

Background. The impact of human genetic background on low-trauma fracture (LTF) risk has not been evaluated in the context of human immunodeficiency virus (HIV) and clinical LTF risk factors. Methods. In the general population, 6 common single-nucleotide polymorphisms (SNPs) associate with LTF through genome-wide association study. Using genome-wide SNP arrays and imputation, we genotyped these SNPs in HIV-positive, white Swiss HIV Cohort Study participants. We included 103 individuals with a first, physician-validated LTF and 206 controls matched on gender, whose duration of observation and whose antiretroviral therapy start dates were similar using incidence density sampling. Analyses of nongenetic LTF risk factors were based on 158 cases and 788 controls. Results. A genetic risk score built from the 6 LTF-associated SNPs did not associate with LTF risk, in both models including and not including parental hip fracture history. The contribution of clinical LTF risk factors was limited in our dataset. Conclusions. Genetic LTF markers with a modest effect size in the general population do not improve fracture prediction in persons with HIV, in whom clinical LTF risk factors are prevalent in both cases and controls.

Objective To review paediatric posterior urethral injuries and the current potential management options; because urethral injury due to pelvic fracture in children is rare and has a low incidence, the management of this type of trauma and its complications remains controversial. Methods We reviewed previous reports identified by searching the PubMed Medline electronic database for clinically relevant articles published in the past 25 years. The search was limited to the keywords ‘pediatric’, ‘pelvic fracture’, ‘urethral injury’, ‘stricture’, ‘trauma’ and ‘reconstruction’. Results Most paediatric urethral injuries are a result of pelvic fractures after high-impact blunt trauma. After the diagnosis, immediate bladder drainage via a suprapubic cystotomy, or urethral realignment, are the initial management options, except for a possible immediate primary repair in girls. The common complications of pelvic fracture-associated urethral injury include urethral stricture formation, incontinence and erectile dysfunction. Excellent results can be achieved with delayed urethroplasty for pelvic fracture-associated urethral injuries. Conclusion Traumatic injury to the paediatric urethra is rare and calls for an immediate diagnosis and management. These devastating injuries have a high complication rate and therefore a close follow-up is warranted to assure adequate delayed repair by a reconstructive urologist. PMID:26019977

Post-traumatic arthritis (PTA) frequently develops after intra-articular fracture of weight bearing joints. Loss of cartilage viability and post-injury inflammation have both been implicated as possible contributing factors to PTA progression. In order to further investigate chondrocyte response to impact and fracture, we have developed a blunt impact model applying 70%, 80% or 90% surface-to-surface compressive strain with or without induction of an articular fracture in a cartilage explant model. Following mechanical loading, chondrocyte viability and apoptosis were assessed. Culture media were evaluated for the release of double-stranded DNA (dsDNA) and immunostimulatory activity via nuclear factor kappa B (NF-κB) activity in Toll-like receptor-expressing Ramos-Blue reporter cells. High compressive strains, with or without articular fracture, resulted in significantly reduced chondrocyte viability. Blunt impact at 70% strain induced a loss in viability over time through a combination of apoptosis and necrosis, whereas blunt impact above 80% strain caused predominantly necrosis. In the fracture model, a high level of primarily necrotic chondrocyte death occurred along the fracture edges. At sites away from the fracture, viability was not significantly different than controls. Interestingly, both dsDNA release and NF-κB activity in Ramos-Blue cells increased with blunt impact, but was only significantly increased in the media from fractured cores. This study indicates that the mechanism of trauma determines the type of chondrocyte death as well as the potential for post-injury inflammation. PMID:23620164

Many U.S. educators now wonder whether they're teachers or targets. This mentality stems from the specter of their school being sanctioned for failing the state accountability tests mandated under No Child Left Behind (NCLB). According to this author, most of those tests are like blunt-edged swords: They function badly in two directions. While…

Current management of high-grade blunt renal trauma favors a nonoperative approach when possible. We performed a retrospective study of high grade blunt renal injuries at our level I trauma center to determine the indications and success of nonoperative management (NOM). 47 patients with blunt grade IV or V injuries were identified between October 2004 and December 2013. Immediate operative patients (IO) were compared to nonoperatively managed (NOM). Of the 47 patients, 3 (6.4%) were IO and 44 (95.6%) NOM. IO patients had a higher heart rate on admission, 133 versus 100 in NOM (P = 0.01). IO patients had a higher rate of injury to the renal vein or artery (100%) compared to NOM group (18%) (P = 0.01). NOM failed in 3 of 44 patients (6.8%). Two required nonemergent nephrectomy and one required emergent exploration resulting in nephrectomy. Six NOM patients had kidney-related complications (13.6%). The renal salvage rate for the entire cohort was 87.2% and 93.2% for NOM. Nonoperative management for hemodynamically stable patients with high-grade blunt renal trauma is safe with a low risk of complications. Management decisions should consider hemodynamic status and visualization of active renal bleeding as well as injury grade in determining operative management. PMID:28018427

Purpose: The most common life-threatening complication of pelvic trauma is bleeding. Arterial bleedings frequently require active management, preferably with transcatheter arterial embolization (TAE). Hemodynamic instability and/or contrast extravasation at computer tomography (CT) examination are reliable indicators of arterial injury. Unstable pelvic fractures are much more hemorrhagic than stable fractures. Nevertheless, an absent or isolated pelvic fracture does not exclude pelvic hemorrhage. Materials and Methods: A retrospective study was conducted on our institutional database by collecting data of patients who underwent pelvic angiography and/or embolization due to pelvic blunt trauma in the period between August 2010 and August 2015. Results: In a period of five years, 39 patients with traumatic pelvic bleeding underwent angiography at our institution. Thirty-six of the 39 (92%) patients did show CT signs of active pelvic bleeding. Nineteen of 39 (49%) patients were hemodynamically unstable at presentation. Three of the 39 patients did not require embolization. Technical success was 35/36 (97%), and overall mortality was 3/39 (8%). Notably, 5/39 (13%) patients did not have any pelvic fracture at presentation, and 18/39 (46%) had only isolated or stable pelvic ring fracture. Conclusions: TAE is an effective technique to treat arterial pelvic bleeding after trauma. The absence of a major pelvic fracture does not exclude the risk of active bleeding requiring prompt treatment. PMID:27625908

Introduction Pancreatoduodenal (PD) injury is an uncommon but serious complication of blunt and penetrating trauma, associated with high mortality. The aim of this study was to assess the incidence, mechanisms of injury, initial operation rates and outcome of patients who sustained PD trauma in the UK from a large trauma registry, over the period 1989–2013. Methods The Trauma Audit and Research Network database was searched for details of any patient with blunt or penetrating trauma to the pancreas, duodenum or both. Results Of 356,534 trauma cases, 1,155 (0.32%) sustained PD trauma. The median patient age was 27 years for blunt trauma and 27.5 years for penetrating trauma. The male-to-female ratio was 2.5:1. Blunt trauma was the most common type of injury seen, with a ratio of blunt-to-penetrating PD injury ratio of 3.6:1. Road traffic collision was the most common mechanism of injury, accounting for 673 cases (58.3%). The median injury severity score (ISS) was 25 (IQR: 14–35) for blunt trauma and 14 (IQR: 9–18) for penetrating trauma. The mortality rate for blunt PD trauma was 17.6%; it was 12.2% for penetrating PD trauma. Variables predicting mortality after pancreatic trauma were increasing age, ISS, haemodynamic compromise and not having undergone an operation. Conclusions Isolated pancreatic injuries are uncommon; most coexist with other injuries. In the UK, a high proportion of cases are due to blunt trauma, which differs from US and South African series. Mortality is high in the UK but comparison with other surgical series is difficult because of selection bias in their datasets. PMID:25723689

We have previously shown that heart-shaped balloons have a different explosion mechanism than spherical balloons in which the former splits into two rubber parts still attached to the balloon base with a backward whiplash motion. This backward whiplash motion may cause significant blunt ocular trauma if the balloon is inflated by mouth. In this article, the energy of the blunt ocular trauma is estimated by the high speed camera photos analysis of the balloon burst. Furthermore, we describe the followup of eight patients with ocular trauma following inflation of heart-shaped balloons.
Since the 1970s, the management of blunt splenic trauma has evolved from almost exclusive surgical management to selective use of nonsurgical management in hemodynamically stable patients. Understanding of the spleen's immunologic importance in protection against overwhelming postsplenectomy infection led to development first of surgical techniques for splenic salvage and later to protocols for nonsurgical management of adults with blunt splenic injury. The evolution of nonsurgical management has resulted in new patterns of postsplenic trauma complications.This article describes a pancreatic pseudocyst, one of several described delayed complications of nonsurgical management of blunt splenic trauma. Along with missed splenic injury and delayed rupture, the development of a splenic pseudocyst represents challenges for any multidisciplinary team involved in trauma care. Detection and management of these complications is discussed, as is postsplenectomy vaccination and return to activity.

Measurements of bone density (BMD) are central to the World Health Organisation (WHO) approach to the definition of osteoporosis. Dual energy X- ray absorptiometry (DXA) remains the gold standard technique for measuring the bone mineral density (BMD) but Quantitative Ultrasound (QUS) is an attractive alternative method of bone assessment because it is easy to use and relatively inexpensive. It has been suggested that QUS could be used as a selective population pre-screen, to maximise the cost effectiveness of referral for DXA assessment of BMD. We set out to examine how such an approach might perform in the assessment of women with low trauma Colles' fracture. In 46 women aged 50-80 (mean 67) years we used DXA to measure BMD at lumbar spine and hip, and heel bone ultrasound to measure Broad Band Attenuation (BUA) and Velocity of Sound (VOS). We calculated local costs of pounds sterling 45 for DXA and pounds sterling 15 for QUS. We identified a BUA threshold of 60 dB/MHz as most cost effective as pre-screen, and calculated a sensitivity of 93% and specificity of 84% in identifying those subjects who were subsequently identified as having osteoporosis by DXA. DXA assessment of all patients had a cost of pounds sterling 77 per osteoporotic subject identified. We examined the cost-effectiveness of using QUS as a pre-screen, only referring subjects for more expensive DXA assessment if BUA was less than 60 dB/MHz. However this approach had no advantage, still costing pounds sterling 78 per osteoporotic subject identified. QUS assessment does not appear cost-effective as a pre-screen for DXA, even in this high risk group of women with low trauma Colles' fracture. A QUS pre-screen would only be cost-effective if the scan could be performed at a substantially lower cost.

Acute traumatic injury during pregnancy is a significant contributor to maternal and fetal morbidity and mortality in the United States. Motor vehicle accidents are the leading cause of injury-related maternal death, followed by violence and assault. Lack of seat belts or other restraints increases the risks of both maternal and fetal morbidity and mortality. The American College of Obstetricians and Gynecologists recommends proper seat belt use by all pregnant women and screening for domestic abuse. Maternal injury and death from physical abuse is prevalent, and in some communities, homicide is a major cause of pregnancy-associated maternal death. Blunt trauma most often occurs as a result of motor vehicle accidents, whereas penetrating trauma results from gunshots or stabbings. Blunt trauma to the abdomen increases the risk for placental abruption, and direct fetal injury is more likely with penetrating trauma. Management strategies in acute maternal trauma must focus on a thorough assessment of the mother. A coordinated team effort that includes the obstetrician is essential to ensure optimal maternal and fetal outcomes. Imaging studies should not be delayed because of concerns of fetal radiation exposure, because the risk is minimal with usual imaging procedures, especially in mid-to-late pregnancy. The obstetrician should serve in a consultative role if nonobstetric surgical care is required and must also be prepared to intervene on behalf of the mother and the fetus if trauma care is compromised by the pregnancy. Perimortem cesarean delivery should be considered early in the resuscitation of a pregnant trauma victim, especially when fetal viability is a concern. Once the mother is stabilized in the emergency setting, she should be transported for appropriate maternal and fetal observation until both mother and fetus are clear of danger. It is essential that the clinician and staff maintain thorough and accurate documentation and recording of the chronology of

Infection is an everyday problem in orthopaedics and is quite common in open fracture management. To study this process and provide a basis to prevent infection, we developed a model that includes trauma (blunt fracture in the fashion of Bonnarens and Einhorn), surgical stabilization (standardized intramedullary K-wire fixation), and infection (Staphylococcus aureus inoculum). In this two-part study, we found that 10(2) colony-forming units of inoculum produced an optimal infection rate of 90-100%, which substantially challenged the immune system without overwhelming sepsis. We hypothesized that, in traumatic fractures, there is a specific immunological response that may lead to an increased rate of infection. In Part 2, we demonstrated immunosuppression (decreased Interleukin-12 levels) at days 6, 10, and 12 after fracture fixation versus nonfractured control groups (p < 0.05). This study describes a rat model of femur factures with osteomyelitis that allows investigation of posttraumatic immunosuppression.

Penile fracture is the disruption of the tunica albuginea with rupture of the corpus cavernosum secondary to blunt trauma to the erect penis. It is an unusual condition, usually underreported. According to the published literature, vigorous vaginal intercourse with women on top position is the most common etiology across the globe including India with Middle Eastern countries being the exception. A total of seven patients of penile fracture presented in emergency in the last 6 months. The etiology was penile manipulation at the time of sexual excitement in six out of seven patients of penile fracture, which was contrary to the literature published except in Middle Eastern countries. All the patients were managed by emergency exploration and repair. Thus, the incidence and etiologies of penile fracture vary according to geographic region, sexual behavior, marital status, and culture.

Pulmonary fat embolism (PFE) is frequently encountered in blunt trauma. The clinical manifestation ranges from no impairment in light cases to death due to right-sided heart failure or hypoxaemia in severe cases. Occasionally, pulmonary fat embolism can give rise to a fat embolism syndrome (FES), which is marked by multiorgan failure, respiratory disorders, petechiae and often death. It is well known that fractures of long bones can lead to PFE. Several authors have argued that PFE can arise due to mere soft tissue injury in the absence of fractures, a claim other authors disagree upon. In this study, we retrospectively examined 50 victims of blunt trauma with regard to grade and extent of fractures and crushing of subcutaneous fatty tissue and presence and severity of PFE. Our results indicate that PFE can arise due to mere crushing of subcutaneous fat and that the fracture grade correlated well with PFE severity (p = 0.011). The correlation between PFE and the fracture severity (body regions affected by fractures and fracture grade) showed a lesser significant correlation (p = 0.170). The survival time (p = 0.567), the amount of body regions affected by fat crushing (p = 0.336) and the fat crush grade (p = 0.485) did not correlate with the PFE grade, nor did the amount of body regions affected by fractures. These results may have clinical implications for the assessment of a possible FES development, as, if the risk of a PFE is known, preventive steps can be taken.

The characteristic wedge-shaped fracture was first described by Messerer (1880) and Bruns (1884) after performing experiments on long bones. Not much later, Messerer (1885) formulated the forensic significance of the direct bending fracture for the detection of the location and direction of blunt impact trauma. He developed the basic biomechanical theory of the origin of this fracture type, which is therefore called Messerer's fracture in the German-speaking world. In the following decades, the findings concerning the origin, specificity and forensic usability of Messerer's fractures were confirmed and supplemented by experiments and case studies. For forensic examinations, it is important to bear in mind that there are exceptions to the rule according to which the level of the wedge-shaped fracture corresponds exactly to the point of impact. The possibility of "false" or "reversed" wedges must also be considered. Already in the 19th century, authors had pointed out the mechanism of indirect formation of wedge-shaped bone fragments. That is why a forensic examination always has to consider the investigation results and medical findings in their entirety. Autopsy of traffic victims is of paramount importance. It must include a thorough examination of clothing, skin, soft tissues and skeletal system using special preparation techniques. The examination of bone injuries in living victims also requires special expertise. If properly applied, valuable results can be obtained by the forensic expert from the wedge-shaped fracture. Until recently, Messerer's fracture was a typical injury sustained by pedestrians hit by vehicles with protruding frontal elements. In modern car production, not only the dimensions of cars have been changed, but the front-end structures have also been modified, e. g. by integrated bumpers. These constructional changes are likely to reduce the frequency of narrow points of impact in collisions. However, further research on the frequency and

This research utilized biplanar radiographs to estimate cross-sectional biomechanical properties for the skeletal remains of two elite individuals from the Early Classic period (ca. AD 400-600) of Copan, Honduras: K'inich Yax K'uk' Mo' (Hunal Burial 95-2), founder of the Early Classic Dynasty at Copan, and the primary female interment (Burial 37-8) from the Motmot tomb. Both individuals survived severe blunt-force insults to the right forearm. Gross skeletal examination and evaluation of the radiographs for K'inich Yax K'uk' Mo' suggest that these traumas resulted from, at least in part, disuse atrophy of the affected forearm skeletal elements. Gross and radiologic evaluation of the Motmot remains countered the possibility that she suffered from a metabolic bone disease, and confirmed the presence of a well-healed parry fracture of the right ulna. The degree of asymmetry in cross-sectional biomechanical properties reported here for K'inich Yax K'uk' Mo' is likely the secondary result of the described blunt-force trauma. The results obtained for the principal Motmot interment are not as dramatic, but suggest subtle changes to humeral cross-sectional geometry subsequent to trauma.

Tension chylothorax following blunt thoracic trauma is an extremely rare condition. Here we report such a case and review its management. A 31-year-old man was involved in a road traffic collision. The car rolled over and the patient was ejected from the vehicle. On arrival at the Emergency Department the patient was conscious and haemodynamically stable. Clinical examination of the chest and abdomen was normal. The patient had sustained fractures of the sixth cervical vertebra and the tenth thoracic vertebra, left pleural effusion, haematoma around the descending aorta and fracture of the right clavicle. The left pleural effusion continued to increase in size and caused displacement of the trachea and mediastinum to the opposite side. An intercostal chest tube was inserted on the left side on the second day. It drained 1500 mL of milky, blood-stained fluid. We confirmed the diagnosis of chylothorax by a histopathological examination of a cell block prepared from the left pleural effusion using Oil red O stain. The patient was managed conservatively with chest tube drainage and fat free diet. The chylothorax completely resolved on the eighth day after the injury. The patient was discharged home on day 16.

Extended length of time from injury to definitive vascular repair is considered to be a predictor of amputation in patients with popliteal artery injuries. In an urban trauma center with a rural catchment area, logistical issues frequently result in treatment delays, which may affect limb salvage after vascular trauma. We examined how known risk factors for amputation after popliteal trauma are affected in a more rural environment, where patients often experience delays in definitive surgical treatment. All adult patients admitted to the Level I trauma center, the University of Mississippi Medical Center, with a popliteal artery injury between January 2000 and December of 2007 were identified. Demographic information management and outcome data were collected. Body mass index, mangled extremity severity score (MESS), Guistilo open fracture score, injury severity score, and time from injury to vascular repair were examined. Fifty-one patients with popliteal artery injuries (53% blunt and 47% penetrating) were identified, all undergoing operative repair. There were nine amputations (17.6%) and one death. Patients requiring amputation had a higher MESS, 7.8 versus 5.3 (P < 0.01), and length of stay, 43 versus 15 days (P < 0.01), compared with those with successful limb salvage. Body mass index, injury severity score, Guistilo open fracture score, or time from injury to repair were not different between the two groups. Patients with a blunt mechanism of injury had a slightly higher amputation rate compared with those with penetrating trauma, 25.9 per cent versus 8.3 per cent (P = non significant). MESS, though not perfect, is the best predictor of amputation in patients with popliteal artery injuries. Morbid obesity is not a significant predictor for amputation in patients with popliteal artery injuries. Time from injury to repair of greater than 6 hours was not predictive of amputation. This study further demonstrates that a single scoring system should be used with

Diaphragm injuries after blunt trauma are uncommon but require early diagnosis to expedite repair. The advancing technology of computed tomography (CT) scanners has improved the detection of almost all traumatic injuries; however, the literature regarding the diagnostic accuracy of CT scan for blunt diaphragm injuries is lacking. The purpose of this study was to determine the CT scan findings in the setting of known blunt diaphragm injury. We performed a retrospective review of all blunt trauma patients with a known diaphragm injury confirmed at laparotomy who also had a preoperative CT scan of the torso. Every CT scan was retrospectively reviewed by a board-certified radiologist for evidence of diaphragm injury as well as associated abdominal and thoracic injuries. Forty-two patients sustaining blunt trauma had preoperative CT scans of the torso and a diaphragm injury confirmed at laparotomy. Only 57 per cent of CT scans showed evidence of diaphragmatic injury. The most common thoracic injury identified was a pulmonary contusion (79%). Although the advancement of imaging technology has markedly improved the diagnosis and management of blunt traumatic injuries, the detection of diaphragm injuries using CT continues to be low and reconstructions do not help in finding diaphragm injuries.

The Vila Franca de Xira Hospital is located in the region with the highest number of festivals and bullfighting activities of Portugal. As a natural consequence, the hospital ends up with a particular experience in the treatment of victims of bullfighting accidents. These are usually common people harvested in street celebrations during the traditional festivals of the region, but also workers such as cattle herders, foremen, ranchers and others who handle the wild cattle and in particular those who deal with the bulls, such as forcados, banderilleros, matadors and cavaleiros. Although we may refer the perforating injuries generated by the horns of bulls, the most frequent injuries are the blunt ones, among them bruises and fractures of the limbs. This work shows the typical striking of a bull horn, showing the violence of the trauma in bullfighting accidents, which in this case resulted only on the fracture of the clavicle from the member hit in the fall.

Venous injuries as a result of blunt trauma are rare. Even though current protocols for multidetector computed tomography (CT) of patients with trauma are designed to evaluate primarily the solid organs and arteries, blunt venous injuries may nevertheless be identified, or at least suspected, on the basis of the multidetector CT findings. Venous injuries are associated with high morbidity and mortality rates. Diagnosis of a possible venous injury is crucial because the physical findings of a venous injury are nonspecific and may be absent. This article aims to make the radiologist aware of various venous injuries caused by blunt trauma and to provide helpful hints to aid in the identification of venous injuries. Multidetector CT technology, in combination with interactive manipulation of the raw dataset, can be useful in the creation of multiplanar reconstructed images and in the identification of a venous injury caused by blunt trauma. Familiarity with direct and indirect signs of venous injuries, as well as with examples of blunt traumatic venous injuries in the chest, abdomen, and pelvis, will help in the diagnosis of these injuries.

Blunt diaphragmatic lesions (BDL) are uncommon in trauma patients, but they should be promptly recognized as a delayed diagnosis increases morbidity and mortality. It is well known that BDL are often overlooked at initial imaging, mainly because of distracting injuries to other organs. Sonography may directly depict BDL only in a minor number of cases. Chest X-ray has low sensitivity in detecting BDL and lesions can be reliably suspected only in case of intra-thoracic herniation of abdominal viscera. Thanks to its wide availability, time-effectiveness and spatial resolution, multi-detector computed tomography (CT) is the imaging modality of choice for diagnosing BDL; several direct and indirect CT signs are associated with BDL. Given its high tissue contrast resolution, magnetic resonance imaging can accurately depict BDL, but its use in an emergency setting is limited because of longer acquisition times and need for patient’s collaboration.

Objective To analyze the outcome of hemodynamically stable patients with blunt hepatic injury managed nonoperatively, and to examine the impact of this approach on the outcome of all patients with blunt hepatic injury. Summary Background Data Until recently, operative management has been the standard for liver injury. A prospective trial from the authors’ institution had shown that nonoperative management could safely be applied to hemodynamically stable patients with blunt hepatic injury. The present study reviewed the authors’ institutional experience with blunt hepatic trauma since that trial and compared the results with prior institutional experience. Methods Six hundred sixty-one patients with blunt hepatic trauma during the 5-year period ending December 1998 were reviewed (NONOP2). The outcomes were compared with two previous studies from this institution: operative 1985 to 1990 (OP) and nonoperative 1993 to 1994 (NONOP1). Results All 168 OP patients were managed operatively. Twenty-four (18%) of 136 NONOP1 patients and 101 (15%) of the 661 NONOP2 patients required immediate exploration for hemodynamic instability. Forty-two (7%) patients failed nonoperative management; 20 were liver-related. Liver-related failures of nonoperative management were associated with higher-grade injuries and with larger amounts of hemoperitoneum on computed tomography scanning. Twenty-four-hour transfusions, abdominal infections, and hospital length of stay were all significantly lower in the NONOP1 and NONOP2 groups versus the OP cohort. The liver-related death rate was constant at 4% in the three cohorts over the three time periods. Conclusions Although urgent surgery continues to be the standard for hemodynamically compromised patients with blunt hepatic trauma, there has been a paradigm shift in the management of hemodynamically stable patients. Approximately 85% of all patients with blunt hepatic trauma are stable. In this group, nonoperative management significantly

Point-of-care ultrasound is well suited for use in the emergency setting for assessment of the trauma patient. Currently, portable ultrasound machines with high-resolution imaging capability allow trauma patients to be imaged in the pre-hospital setting, emergency departments and operating theatres. In major trauma, ultrasound is used to diagnose life-threatening conditions and to prioritise and guide appropriate interventions. Assessment of the basic haemodynamic state is a very important part of ultrasound use in trauma, but is discussed in more detail elsewhere. Focussed assessment with sonography for Trauma (FAST) rapidly assesses for haemoperitoneum and haemopericardium, and the Extended FAST examination (EFAST) explores for haemothorax, pneumothorax and intravascular filling status. In regional trauma, ultrasound can be used to detect fractures, many vascular injuries, musculoskeletal injuries, testicular injuries and can assess foetal viability in pregnant trauma patients. Ultrasound can also be used at the bedside to guide procedures in trauma, including nerve blocks and vascular access. Importantly, these examinations are being performed by the treating physician in real time, allowing for immediate changes to management of the patient. Controversy remains in determining the best training to ensure competence in this user-dependent imaging modality.

Introduction Gastric emphysema or pneumatosis is a rare finding. Early endoscopy and urgent laparotomy is advised in post-trauma patients. Case Presentation A 29 year old man presented with blunt abdominal injury following a high-speed motorbike crash He complained of abdominal pain and abdomen was distended. CT abdomen revealed air in the gastric wall with disruption of gastric mucosa. He had normal white cell counts, bleeding parameters and blood gases. He was treated conservatively with nasogastric decompression, intravenous analgesics and antibiotics with which he recovered well. Conclusions Early surgical management is indicated in post-trauma patients in whom bowel infarction is suspected. In a stable patient, a negative laparotomy is a major additional stress post trauma - conservative management with close clinical observation is a suitable management alternative. PMID:24396802

Male genital trauma is a rare but potentially serious sports injury. Although such an injury can occur by many different mechanisms, including falls, collisions, straddle injuries, kicks, and equipment malfunction, the clinical presentation is typically homogeneous, characterized by pain and swelling. Almost all sports-related male genital injury comes from blunt force trauma, with involvement of scrotal structures far more common than penile structures. Most injuries can be treated conservatively, but catastrophic testicular injury must first be ruled out. Despite being relatively uncommon compared with other sports injuries, more than half of all testicular injuries are sustained during sports.

Intestinal injury is frequent after non-penetrating abdominal trauma, particularly after modern, high-energy transfer impacts. Under these circumstances, delay in the diagnosis of perforation is a major contributor to morbidity and mortality. This study establishes patterns of intestinal injury after blunt trauma by non-penetrating projectiles and examines relationships between injury distribution and abdominal wall motion. Projectile impacts of variable momentum were produced in 31 anaesthetised pigs to cause abdominal wall motion of varying magnitude and velocity. No small bowel injury was observed at initial impact velocity of less than 40 m/s despite gross abdominal compression. At higher velocity, injury to the small bowel was frequent, irrespective of the degree of abdominal compression (P = 0.00044). Large bowel injury was observed at all impact velocities and at all degrees of abdominal compression. This study confirms the potential for intestinal injury in high velocity, low momentum impacts which do not greatly compress the abdominal cavity and demonstrates apparent differences in injury mechanisms for the small bowel and colon. Familiarity with injury mechanisms may reduce delays in the diagnosis of intestinal perforation in both military and civilian situations.

Multiple trauma in children is rare so that even large trauma centers will only treat a small number of cases. Nevertheless, accidents are the most common cause of death in childhood whereby the causes are mostly traffic accidents and falls. Head trauma is the most common form of injury and the degree of severity is mostly decisive for the prognosis. Knowledge on possible causes of injury and injury patterns as well as consideration of anatomical and physiological characteristics are of great importance for treatment. The differences compared to adults are greater the younger the child is. Decompression and stopping bleeding are the main priorities before surgical fracture stabilization. The treatment of a severely injured child should be carried out by an interdisciplinary team in an approved trauma center with expertise in pediatrics. An inadequate primary assessment involves a high risk of early mortality. On the other hand children have a better prognosis than adults with comparable injuries.

Rib fractures may be dismissed as clinically insignificant, or of secondary importance in a patient presenting with other serious injuries, especially if the patient is young. This study assesses the effect of concomitant rib injuries on fatality risk following a car crash, and compares the effect as a function of patient age. The National Trauma Databank was sampled to identify 181,331 adults that were in motor vehicle crashes and had complete data available. Characteristics among several populations were compared, including the association between rib fractures and fatality risk in two age groups (18 to 45 years old and over 64 years old). Descriptive statistics were compiled to contrast the injury patterns and outcomes. Propensity scores were then generated using logistic regression, where the "treatment group" was those patients with rib fractures of at least an abbreviated injury scale (AIS) 3. Covariates for generating the propensity score included gender and the presence or absence of AIS 3, 4 or greater injuries to the head, abdomen or pelvis. Matching was performed using calipers on the propensity scores for all patients within the two age groups. Odds ratios for the outcome death were calculated for the matched datasets and compared between the two age groups. The probability that an adult with automotive blunt trauma had a rib injury as the maximum AIS (MAIS) increased significantly (p<0.001) with age. Furthermore, the probability of the patient having an MAIS defined by rib fractures increased significantly with age for adults who died with a thoracic MAIS: from 30.4% at age 21 to 51.3% at age 65. Rib fractures defined the MAIS for 55.9% of all patients over age 60 who died with a thoracic MAIS. In other words, over 55% of patients over 60 who died of a chest injury had no injury worse than rib injuries. The odds ratio for death for younger patients (aged 18-45) was 1.4 (95% CI 1.3-1.6) if rib fractures of at least AIS 3 or greater were present. For

In the many years Dr. William R. Maples served as a forensic anthropologist, he saw diverse sources of trauma presented in the victims of violent crime, accident and suicide in the state of Florida. In 1996 the District 18 Medical Examiner's Office of Florida requested the assistance of Dr. Maples in the analysis of human remains recovered by the U.S. Coast Guard. The deceased was in an advanced state of decomposition characterized by skin slippage and discoloration. The torso bore multiple lacerations, including nearly parallel lacerations in the skin of the back. Specimens were carefully macerated and the fractures reconstructed. The skeletal trauma was caused by a device capable of delivering robust cuts and blunt trauma in linear paths, as is consistent with propeller trauma. Unusual in this case were blows to the ventral and dorsal surfaces of the body. Based on the anthropological analysis and interviews with the family of the deceased, the F.B.I. proceeded with the case as a homicide investigation.

Between July 1987 and December 1990 in Washington, DC, 116 patients sustained 146 fractures and seven dislocations due to an assault with a baseball bat. The ulna was the most common site of trauma (61 fractures), followed by the hand (27 injuries) and the radius (14 injuries). Forty-two of the 146 fractures were significantly displaced and required open reduction and internal fixation to restore satisfactory alignment. Twenty-nine of the 146 fractures were open fractures. Treatment protocol for open fractures consisted of irrigation and debridement, antibiotic therapy, and bone stabilization with either internal or external fixation, or casting. Recognition of the severity of the soft tissue and bone damage is important in the management of musculoskeletal trauma secondary to the baseball bat. Images Figure 1 Figure 2 Figure 3 PMID:1460683

The profile and pattern of abdominal trauma is changing with progressing civilisation. We are lacking epidemiological data from most parts of the world. This study was conducted to prepare a database in our set up and look into the pattern of abdominal trauma, make an aetiological correlation of abdominal trauma with the types of injuries, identify the preventable factors causing delay in intervention and, compare the data with the other available national and international data. This prospective, observational study was done in a teaching hospital in a metropolitan city of eastern India. Records of patients with abdominal trauma were collected in predesigned forms, from admission to discharge. Data were analysed applying standard statistical techniques. Males (87.3%) predominated with the age range between 21 and 30 years, and the majority (73.5%) had blunt abdominal trauma. Compression injury (57.3%) commonly caused blunt trauma and stab injuries caused majority of penetrating trauma. The commonest organ injured both in blunt and penetrating trauma was small bowel (30.7% and 33.3% respectively). It was found that prehospital trauma care is virtually non-existent in this region. We are lacking a uniform protocol for the management of abdominal trauma across the hospitals. With the availability of better investigational modalities we are moving more towards a conservative approach to the abdominal trauma patients, especially the blunt abdominal trauma patients with solid organ injuries.

Patients affected by cranial trauma with depressed skull fractures and increased intracranial pressure generally undergo neurosurgical intervention. Because craniotomy and craniectomy remove skull fragments and generate new fracture lines, they complicate forensic examination and sometimes prevent a clear identification of skull fracture etiology. A 3-dimensional reconstruction based on preoperative computed tomography (CT) scans, giving a picture of the injuries before surgical intervention, can help the forensic examiner in identifying skull fracture origin and the means of production.We report the case of a 41-year-old-man presenting at the emergency department with a depressed skull fracture at the vertex and bilateral subdural hemorrhage. The patient underwent 2 neurosurgical interventions (craniotomy and craniectomy) but died after 40 days of hospitalization in an intensive care unit. At autopsy, the absence of various bone fragments did not allow us to establish if the skull had been stricken by a blunt object or had hit the ground with high kinetic energy. To analyze bone injuries before craniectomy, a 3-dimensional CT reconstruction based on preoperative scans was performed. A comparative analysis between autoptic and radiological data allowed us to differentiate surgical from traumatic injuries. Moreover, based on the shape and size of the depressed skull fracture (measured from the CT reformations), we inferred that the man had been stricken by a cylindric blunt object with a diameter of about 3 cm.

This study was undertaken to evaluate the frequency, distribution, cause, pattern, and outcome of patients suffering from major trauma in the State of Victoria over a 1-year period. No previous study in Australia has attempted a comprehensive regional analysis of major trauma. All major trauma admissions resulting from blunt, penetrating, and burns injury were identified, and data collected from emergency departments and intensive care log books at 25 major metropolitan and rural hospitals from the January 3, 1992 to February 28, 1993 by onsite data collectors. The total number of patients admitted into the study was 2,944. There were 1,076 major trauma cases with an Injury Severity Score greater than 15 in a population of 4.2 million people. The type of injury was predominantly blunt (87.5%), with only a small percentage of penetrating injuries (6.4%) and burns (6%). Major trauma in pediatric cases is less common (132 cases). The most common causes of injury were road transport (56%) and falls (22%). The overall outcome of the group was favorable when compared with the Major Trauma Outcome Study group (Z = 1.4, M = 0.93, W = 0.52). There was an unexpectedly low number of patients suffering from major trauma. Outcome using Trauma and Injury Severity Score methodology was favorable when compared with North America.

Thyroid crisis, also known as thyroid storm, is a rare complication of thyrotoxicosis that results in a hypermetabolic and hyperadrenergic state. This condition requires prompt recognition and treatment because the mortality from thyroid crisis approaches 30%. Thyrotoxicosis alone will usually not progress to thyroid crisis. Thyroid crisis will typically be precipitated by some concomitant event such as infection, iodine-containing contrast agents, medications such as amiodarone, pregnancy, or surgery. Trauma is a rare precipitator of thyroid crisis. Several published studies have reported thyroid crisis resulting from blunt or penetrating neck trauma. Significant systemic trauma, such as motor vehicle accidents, has also been reported to precipitate thyroid crisis. It is very unusual for minor trauma to precipitate thyroid crisis. In the present study, we report the case of a patient who had incurred relatively minor maxillofacial trauma and developed thyroid crisis 2 weeks after the initial trauma.

Summary Background: The aim of the paper was to evaluate the usefulness of ultrasonographic examination in diagnosing laryngeal traumas, and monitoring the progress or complications in its treatment. Material/Method: In the years 2004–2009, 12 children, including 5 girls and 7 boys with laryngeal injuries, aged 5–12 years, were diagnosed and treated. In all the children, US examination of the neck and larynx, using a high-frequency linear transducer, as well as laryngoscopy and radiological examination of the cervical spine and chest were performed. Results: Blunt injury of the larynx was found in 12 children; in 9 children, the injury had been caused by hitting the neck against an obtuse object, 1 child had been kicked in the neck, and in one there had been an attempt of strangling. One of the children had sustained blunt injuries of the neck and chest in a traffic accident. In US examinations, the findings included: unilateral lack of vocal cord mobility in 5 children, asymmetry in vocal cord mobility in 1 child, fractured thyroid cartilage with local hematoma in the affected area in 2 children, and thickened vocal cords in 5 children. In radiological examination, the findings included: subcutaneous emphysema in the cervical area of the chest in 4 children, and mediastinal emphysema in 2 children with traumatic rupture of the trachea shown in laryngoscopy. Conclusions: US examination is helpful in the assessment of the extensiveness of laryngeal trauma, especially in the evaluation of vocal cord mobility, cervical cartilage and the soft tissues of the neck. A high level of conformity was demonstrated between the results of cervical US and the respective laryngoscopic findings. US examination does not allow to differentiate between vocal cord paralysis and their immobilization. PMID:22802823

We analyzed reasons, numbers and results of arterial lesions accompanying fractures (n = 21) and luxations (n = 6) in a 6-year-period (1993-1998) retrospectively. Traffic accidents were in nearly 50% responsible for the injuries. 8 patients had suffered multiple injuries. In 17 patients the lower, and in 10 patients the upper extremities were affected. The vascular wall was completely disrupted or severed in 74%. In 7 cases (26%), patients had suffered blunt or indirect arterial trauma with intima- and media-lacerations due to subcapital fracture of the humerus (n = 2), fractured femoral bone (n = 1), luxation of the knee joint (n = 3) or the elbow (n = 1). The mean preoperative time period was 6 hours and 20 minutes (2 to 16 hours) in patients with complete ischaemia. Vascular reconstruction was performed by interposition of an autologous vein graft or an autologous venous bypass (n = 20), by direct reconstruction and primary suturing (n = 2), by use of a venous patch plasty (n = 2) and, in a single case, by autologous bypass procedure. In one case, a crural artery was ligated, in another case with a Mangled Extremity Severity Score (MESS) of 7 points a primary amputation of the lower leg was necessary. In 5 patients (19%) secondary amputations were performed. No patient died. The final outcome is mostly influenced by the preoperative period of ischaemia.

Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon. There are 5 types of vascular injury: intimal injury (flaps, disruptions, or subintimal/intramural hematomas), complete wall defects with pseudoaneurysms or hemorrhage, complete transections with hemorrhage or occlusion, arteriovenous fistulas, and spasm. Intimal defects and subintimal hematomas with possible secondary occlusion are most commonly associated with blunt trauma, whereas wall defects, complete transections, and arteriovenous fistulas usually occur with penetrating trauma. Spasm can occur after either blunt or penetrating trauma to an extremity and is more common in young patients. Clinical presentation of vascular injury may not be straightforward. Physical examination can be misleading or initially unimpressive; a normal pulse examination may be present in 5% to 15% of patients with vascular injury. Detection and treatment of vascular injuries should take place within the context of the overall resuscitation of the patient according to the established principles of the Advanced Trauma Life Support (ATLS) protocols. Advances in the field, made mostly during times of war, have made limb salvage the rule rather than the exception. Teamwork, familiarity with the often subtle signs of vascular injuries, a high index of suspicion, effective communication, appropriate use of imaging modalities, sound knowledge of relevant technique, and sequence of surgical repairs are among the essential factors that will lead to a successful outcome. This article provides a comprehensive literature review on a subject that generates significant controversy and confusion among clinicians involved in the care of trauma patients.

The skeletal remains of eight Australian Aboriginals with healed depressed skull fractures were examined. Male:female ratio 5:3; age range 20-60 yrs. Burial dates by (14) C dating in three cases were 500 years BP (n = 2) and 1300 BP. There were 13 healed depressed skull fractures manifested by shallow indentations of cortical bone and thinning of diploe, with no significant disturbance of the inner skull tables. Nine (69%) were located within 35 mm of the sagittal suture/midline. These lesions represent another acquired feature that might be helpful in suggesting that a skull is from a tribal Aboriginal individual and may be particularly useful if the remains are represented by only fragments of calvarium. While obviously not a finding specific to this population, these healed injuries would be consistent with the possible results of certain types of conflict behavior reported in traditional Aboriginal groups that involved formalized inflicted blunt head trauma.

A case is presented of a 24-year-old man who sustained a forceful blow to the right side of the abdomen during a tackle while playing rugby union. The patient was thought to be “winded” and could not play on. He sought medical attention several hours later at the local hospital where initial evaluation revealed mild right iliac fossa tenderness with no signs of peritonism and clinical parameters showed haemodynamic stability. Subsequent ultrasound and CT evaluation revealed a large haematoma involving the caecum and ascending colon. Emergency right haemicolectomy with primary anastomosis was performed to remove the large haematoma within the intact colonic wall. He was observed in the high dependency unit and was discharged after 7 days following an uneventful postoperative course. He continues to make significant progress some 3 months later and a full return to contact sport is being proposed within 9–12 months. PMID:21754953

We present two separate cases of young male patients with congenital kidney anomalies (horseshoe and crossed fused renal ectopia) identified following blunt abdominal trauma. Despite being rare, ectopic and fusion anomalies of the kidneys are occasionally noted in a trauma patient during imaging or upon exploration of the abdomen. Incidental renal findings may influence the management of traumatic injuries to preserve and protect the patient's renal function. Renal anomalies may be asymptomatic or present with hematuria, flank or abdominal pain, hypotension, or shock, even following minor blunt trauma or low velocity impact. It is important for the trauma clinician to recognize that this group of congenital anomalies may contribute to unusual symptoms such as gross hematuria after minor trauma, are readily identifiable during CT imaging, and may affect operative management. These patients should be informed of their anatomical findings and encouraged to return for long-term follow-up. PMID:27895945

If the septal component of a nasal injury is adequately managed, usually the entire nasal injury will be well managed. Major or minor nasal trauma can cause cartilage fracture, deviation, dislocation, hematoma, or abscess formation, and the various associated sequelae, some of them life-threatening. A negative x-ray report should never be used as a substitute for a complete intranasal examination in any child with nasal trauma. Any nasal abnormality should be referred for immediate evaluation and treatment.

Background: Vascular trauma associated with bony injuries is an orthopaedic emergency. Lack of timely intervention can lead to loss of limb or even life. Inspite of the rising incidence of high speed road traffic accidents in India, there is paucity of literature regarding the demographic pattern, clinical morbidity, management strategies and outcome of arterial injuries associated with lower limb trauma. The aim of this study is to describe the epidemiology and outcome of lower extremity musculoskeletal trauma with associated vascular injuries in a tertiary care institute in India. Materials and Methods: All individuals who presented to our tertiary care trauma center from July 2013 to December 2014 with lower extremity vascular injury associated with lower limb fractures were identified from a retrospective trauma database for this descriptive study. For the 17 months, there were 82 lower extremity vascular trauma cases admitted in our trauma center, of which 50 cases were included in the study. 32 patients with crush injuries, traumatic amputations, and those with head injury and blunt trauma to chest or abdomen were excluded from the study. Results: Out of the 50 cases of lower extremity vascular injury with associated lower limb fractures, 19 limbs were salvaged, 28 amputated, and three patients expired. Young males in the age group of 20–39 years were frequently injured. Motor vehicle accident (MVA) (82%) was found to be the most common cause followed by pedestrian injury. Popliteal artery (62%) was the most common vessel injured, followed by femoral artery (28%). The salvageability percentage was much higher (64%) in the femoral artery injury group when compared to popliteal artery injury group (25%). There were 32 open fractures, with amputation rates (60%) being higher and all three cases of death falling in this group. In addition, the limb salvageability percentage was 43.2% when the patient presented within 12 h of injury and this decreased to a mere

Extraperitoneal bleeding from the inferior epigastric artery (IEA) and its branches is a rare complication of blunt pelvic trauma; however, it can result in life-threatening hemorrhage, even in cases of minimally displaced fractures of the pelvic ring. We report the case of a patient who had posttraumatic pelvic hematoma and cardiovascular collapse caused by avulsion of the right pubic branch of the IEA related to undisplaced fractures of the pubic rami. CT scanning followed by angiography showed leakage of contrast from the IEA. Transcatheter arterial embolization was performed to successfully control the hemorrhage. There have been very few previous reports of IEA injury related to stable fractures of the pubic rami successfully treated by transcatheter arterial embolization.

Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

Injuries to the great vessels of the torso are commonly seen and managed in busy urban trauma centers. This same injury complex is rarely seen in military conflicts, likely because of the high kinetic energy of weapons causing the wounds seen in this setting. Although most of the great advancements in trauma surgery over the past century have generally resulted from our wartime experience, civilian centers have contributed greatly to the understanding and management of torso vascular injuries. This article reviews the presentation and management of injuries to the great vessels of the torso from major penetrating and blunt trauma.

We present the results of the analyses of traumatic bone injuries in two Late Antique (3r to 5th century AD) skeletal samples from Croatia: Zadar--located on the eastern Adriatic coast, and a composite skeletal series from continental Croatia consisting of skeletons from Osijek, Vinkovci, Strbinci, and Zmajevac. The osteological series from continental Croatia are related to settlements located on, or near the Danubian military border, while Zadar--350 km to the west, is located deep in the territory of the Roman Empire. Numerous historical sources describe barbaric incursions, as well as large battles related to civil wars during the Late Antique period in continental Croatia. Conversely, there is no mention of similar events in the Zadar region. In accordance with these data our analysis tests the hypothesis that the inhabitants of continental Croatia were exposed to greater levels of violence than those living in Zadar. Analysis of bone traumas in the two series shows a similar, relatively high prevalence of long bone fractures in both samples, with a slightly higher frequency recorded in Zadar. Both series exhibit a high frequency of cranial injuries with, once again, higher frequencies recorded in the Zadar series. Additionally, two perimortem cranial fractures (one caused by a sword, the other by a blunt object) were observed in Zadar. Some of the recorded traumas in both samples resulted from accidents, but a number of injuries clearly resulted from intentional violence of lesser intensity. Further multidisciplinary research incorporating osteological, archaeological, and historical analyses is necessary to confirm the results obtained from these samples.

Background Sternal fractures are relatively rare, and caused mainly by blunt anterior chest wall trauma. In most cases, sternal fractures are treated conservatively. However, if the patient exhibits problematic symptoms such as intractable chest wall pain or bony crepitus due to sternal instability, surgical correction is indicated. But no consensus exists regarding the most appropriate surgical method. We analyzed the results of surgical fixation in cases of sternal fracture in order to identify which surgical method led to the best outcomes. Methods We retrospectively reviewed the medical records of patients with sternal fractures from December 2008 to December 2011, and found 19 patients who underwent open reduction and internal fixation of the sternum with a longitudinal plate (L-group) or a T-shaped plate (T-group). We investigated patients’ characteristics, clinical details regarding each case of chest trauma, the presence of other associated injuries, the type of open reduction and fixation, whether a combined operation was performed, and postoperative complications. Results Of the 19 patients, 10 patients (52.6%) were male, and their average age was 56.8 years (range, 32 to 82 years). Seven patients (36.8%) had isolated sternal fractures, while 12 (63.2%) had other associated injuries. Seven patients (36.8%) were in the L-group and 12 patients (63.2%) were in the T-group. Three patients in the L-group (42.9%) showed a loosening of the fixation. In all patients in the T-group, the fracture exhibited stable alignment. Conclusion Open reduction and internal fixation with a T-shaped plate in sternal fractures is a safer and more efficient treatment method than treatment with a longitudinal plate, especially in patients with a severely displaced sternum or anterior flail chest, than a longitudinal plate.

Introduction: Despite radiography being the gold standard in evaluation of orthopedic injuries, using bedside ultrasonography has several potential supremacies such as avoiding exposure to ionizing radiation, availability in pre-hospital settings, being extensively accessible, and ability to be used on the bedside. The aim of the present study is to evaluate the diagnostic accuracy of ultrasonography in detection of extremity bone fractures. Methods: This study is a case series study, which was prospectively conducted on multiple blunt trauma patients, who were 18 years old or older, had stable hemodynamic, Glasgow coma scale 15, and signs or symptoms of a possible extremity bone fracture. After initial assessment, ultrasonography of suspected bones was performed by a trained emergency medicine resident and prevalence of true positive and false negative findings were calculated compared to plain radiology. Results: 108 patients with the mean age of 44.6 ± 20.4 years were studied (67.6% male). Analysis was done on 158 sites of fracture, which were confirmed with plain radiography. 91 (57.6%) cases were suspected to have upper extremity fracture(s) and 67 (42.4%) to have lower ones. The most frequent site of injuries were forearm (36.7%) in upper limbs and leg (27.8%) in lower limbs. Prevalence of true positive and false negative cases for fractures detected by ultrasonography were 59 (64.8%) and 32 (35.52%) for upper and 49 (73.1%) and 18 (26.9%) for lower extremities, respectively. In addition, prevalence of true positive and false negative detected cases for intra-articular fractures were 24 (48%) and 26 (52%), respectively. Conclusion The present study shows the moderate sensitivity (68.3%) of ultrasonography in detection of different extremity bone fractures. Ultrasonography showed the best sensitivity in detection of femur (100%) and humerus (76.2%) fractures, respectively. It had low sensitivity in detection of in intra-articular fractures.

Fractures of the forefoot are common and comprise approximately two thirds of all foot fractures. Forefoot fractures are caused by direct impact or the effect of indirect force. The forces exerted can range from repetitive minor load (stress fractures) to massive destructive forces (complex trauma). The clinical course in forefoot fractures is typically more favourable than in fractures of the mid- and hindfoot. The incidence of complications like infection or pseudarthrosis is low. Exceptions are rare fractures of the proximal shaft of the fifth metatarsal and the sesamoids with higher pseudarthrosis rates. Malunited metatarsal fractures can cause painful conditions that should even be treated operatively. Differences in structure and function of the different forefoot areas and specific fracture types require an adapted management of these special injuries.

Preceding trauma may play a role in the etiology and pathogenesis of hematogenous bone and joint infections. Among 345 children with an acute hematogenous bone and/or joint infection, 20% reported trauma during a 2-week period leading to infection. Blunt impact, bruises, or excoriations were commonly reported. The rate was similar to that in the general pediatric population obtained from the literature. In the study group, patients with and without trauma were similar in age, serum C-reactive protein and erythrocyte sedimentation rate, length of hospitalization, and late sequelae. Preceding minor trauma did not prove to be significant as an etiological or as a prognostic factor.

Rarely seen fractures are presented in this study. One case was a calcaneal spur, 2 cases osteochondroma pedicule fractures and talus posteromedial tubercle fracture due to direct trauma. Calcaneal spur and osteochondromas were removed surgically and posteromedial tubercle was treated by short-leg cast immobilization. In conclusion, we think that fractures of osteochondroma and calcaneal spur may be treated by surgical removal which do not cause any functional disorders after this operation, but fractures like the talus posteromedial tubercle should be treated conservatively by short-leg immobilization in the early period.

Timing of blunt force trauma in human bone is a critical forensic issue, but there is limited knowledge on how different environmental conditions, the duration of postmortem interval (PMI), different bone types and different animal models influence fracture morphology. This study aims at evaluating the influence of the type of postmortem environment and the duration of the postmortem period on fracture morphology, for distinguishing perimortem from postmortem fractures on different types of long bones from different species. Fresh limb segments from pig and goat were sequentially left to decompose, under 3 different environmental circumstances (surface, buried and submerged), resulting in sets with different PMI lengths (0, 28, 56, 84, 112, 140, 168 and 196 days), which were then fractured. Fractured bones (total=325; pig tibia=110; pig fibula=110; goat metatarsals=105) were classified according to the Fracture Freshness Index (FFI). Climatic data for the experiment location was collected. Statistical analysis included descriptive statistics, correlation analysis between FFI and PMI, Mann-Whitney U tests comparing FFI medians for different PMI's and linear regression analysis using PMI, pluviosity and temperature as predictors for FFI. Surface samples presented increases in FFI with increasing PMI, with positive correlations for all bone types. The same results were observed in submerged samples, except for pig tibia. Median FFI values for surface samples could distinguish bones with PMI=0 days from PMI≥56 days. Buried samples presented no significant correlation between FFI and PMI, and nonsignificant regression models. Regression analysis of surface and submerged samples suggested differences in FFI variation with PMI between bone types, although without statistical significance. Adding climatic data to surface regression models resulted in PMI no longer predicting FFI. When comparing different animal models, linear regressions suggested greater increases in

First rib fractures are scarce due to their well-protected anatomic locations. Bilateral first rib fractures accompanying bilateral scapular fractures are very rare, although they may be together with scapular and clavicular fractures. According to our knowledge, no case of bilateral first rib fractures accompanying bilateral scapular fractures has been reported, so we herein discussed the diagnosis, treatment, and complications of bone fractures due to thoracic trauma in bias of this rare entity.

Despite the high incidence and prognostic relevance of hemorrhagic shock and abdominal and blunt chest trauma in multiply injured patients, there are no animal models combining these injuries. Therefore, we established a new porcine multiple trauma model consisting of blunt chest trauma, penetrating abdominal trauma (two incisions in the right upper liver lobe using a four-edged scalpel and subsequent liver packing), and pressure-controlled hemorrhagic shock with a mean arterial pressure of 30 ± 5 mmHg (a maximum of 45% of the total blood volume). The combined traumatic insult led to severe signs of hemorrhagic shock and impaired pulmonary function. In conclusion, a consistent, reproducible, and clinically relevant porcine model of multisystem injury with controlled (pressure-controlled blood withdrawal) and uncontrolled components of hemorrhage (liver laceration) with the potential for rebleeding was established.

Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

Introduction In medico-legal evaluation of trauma patients, the bio-psychological effects of the trauma and the severity of the injuries require to be evaluated. In this study, assuming the fact that psychiatric assessment is not taken into consideration in physical trauma cases, we planned to show the presence of psychological trauma in our medico-legally evaluated patients who presented with different types of traumas and to review the mental findings and diagnoses in trauma victims. Method We retrospectively analyzed the hospital records of 1975 patients aged 18 years or older who presented to the Department of Forensic Medicine at Dokuz Eylül University School of Medicine for medico-legal evaluation between 1999 and 2009. Psychiatric assessment was performed in 142 patients by the Department of Psychiatry. The data contained in medico-legal reports and patient records were then examined with respect to patients’ age, gender, nature of traumatic events, psychiatric diagnoses, descriptive characteristics of the patients, severity of trauma and past history of mental disorder and trauma experience. Results of the medicolegal evaluations were also analyzed. Result Of the 142 patients, 80 (56.3%) were female and their average age was 40.30±17.17 years. The most frequent traumatic events were traffic accidents (29.6%) and violence-related blunt force trauma (28.9%). When the distribution of the most common psychiatric diagnoses was examined, it was found that anxiety disorders were found in 69 cases (48.6%), adjustment disorders were found in 16 cases (11.3%) and mood disorders were found in 12 cases (8.5%). Among anxiety disorders, acute stress disorder (n=39) and post-traumatic stress disorder (PTSD) (n=27) were the most common ones. In 27 cases of the 142, it was determined that, psychiatric symptoms and findings did not meet the diagnostic criteria of any psychiatric disorder. Diagnosis of psychiatric disorder was not significantly related with traumatic

To investigate what is currently known about skeletal blunt force trauma (BFT) resulting from falls, and how valuable that research is in contributing to forensic anthropology investigations and interpretations of circumstances of death, a comprehensive review of forensic anthropology, forensic pathology and clinical medicine literature was performed. Forensic anthropology literature identified that establishing the type of fall from the analysis of BFT is difficult given the uniqueness of each fall event, the complexities involved with identify BFT and, in particular, the limited available research documenting fracture patterning and morphologies. Comparatively, skeletal BFT resulting from fatal falls is well documented in the forensic pathology and clinical medicine literature. These disciplines cover a wide range of fall types (free falls, falls in juveniles, specific fractures produced from falls, falls down staircases, falls resulting in impalements, and 'other' fall types), provide details on how the nature of the fall influences the skeletal fracturing, and documents the anatomical regions susceptible to fracturing. Whilst these contributions may assist forensic anthropologists, they provide limited details of fracture patterns and morphologies and thus further research investigating the details of skeletal BFT resulting from fatal falls is required.

The present study describes 3 patients of previous facial trauma who have subsequently been treated with functional endoscopic sinus surgery. The authors want pay attention on the possible correlation between facial trauma and sinusitis. Such fractures can be the cause of onset of paranasal sinusitis or of worsening of a previous sinusitis. The correlation between these 2 pathologies could be due to the fact that facial fractures concern the anatomic structures of paranasal sinuses. The damage to these structures during the facial trauma and tissue regeneration after injury or surgical treatment subverts the anatomy and function of the sinuses in a basically compromised situation.

Ketamine is a promising alternative agent for pain control that offers benefit to traditional strategies, particularly in the setting of rib fracture. Current pharmacologic therapies have clear adverse effects, and other options may be invasive, cost prohibitive, or marginally effective. We describe three consecutive patients with traumatic injuries including rib fracture for which a ketamine infusion was utilized as part of their pain control strategy. For each patient, use of a ketamine infusion trended toward reduced opioid requirements with stable pain scores. One patient experienced a dissociative adverse effect prompting decrease and discontinuation of ketamine. No pulmonary complications in the form of emergent intubation or new diagnosis of pneumonia were observed. We believe the addition of ketamine infusion to be a valid alternative strategy for managing pain associated with rib fracture. PMID:27540552

Less-lethal ballistic projectiles are used by police personnel to temporarily incapacitate suspects. While the frequency of these impacts to the head is low, they account for more serious injuries than impacts to any other body region. As a result, there is an urgent need to assess the tolerance of the head to such impacts. The focus of this study was to investigate the tolerance of the temporo-parietal skull to blunt ballistic impact and establish injury criteria for risk assessment. Seven unembalmed isolated cadaver heads were subjected to fourteen impacts. Specimens were instrumented with a nine-accelerometer array as well as strain gages surrounding the impact site. Impacts were performed with a 38 mm instrumented projectile at velocities ranging from 18 to 37 m/s. CT images and autopsies were performed to document resulting fractures. Peak fracture force for the seven resulting fractures was 5633+/-2095 N. Peak deformation for fracture-producing impacts was 7.8+/-3.2 mm. The blunt criterion (BC), peak force and principal strain were determined to be the best predictors of depressed comminuted fractures. Temporo-parietal tolerance levels were consistent with previous studies. An initial force tolerance level of 2346 N is established for the temporo-parietal region for blunt ballistic impact with a 38 mm diameter impactor.

Transstyloid, transscaphoid, transcapitate fractures are uncommon. We report the case of a 28-year-old man who sustained this fracture following direct trauma. The patient was successfully treated by open reduction internal fixation of the scaphoid and proximal capitate fragment, with a good clinical outcome at 1-year follow-up. This pattern is a new variant of scaphocapitate fracture as involves a fracture of the radial styloid as well. PMID:24686808

The human face contains the sense organs and is responsible for essential functions: swallowing, chewing, speech, breathing and communication. It is also and most importantly the seat of a person's identity. Multiple trauma adds a life-threatening dimension to the physical and psychological impact of a facial trauma.

Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair. PMID:26770280

Transphyseal distal humerus fractures typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a successful outcome. Recognizing that the forearm is not aligned with the humerus on plain radiographs may aid in the diagnosis of a transphyseal distal humerus fracture. Surgical management is most commonly performed with the aid of an arthrogram. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed. Cubitus varus caused by a malunion, osteonecrosis of the medial condyle, or growth arrest is the most common complication encountered in the treatment of transphyseal distal humerus fractures. A corrective lateral closing wedge osteotomy can be performed to restore a nearly normal carrying angle.

Selective nonoperative management is appropriate for most blunt splenic injuries in adults and children, but the efficacy of this approach is unknown when injury occurs in patients with concurrent infectious mononucleosis. We have reviewed our experience during the past 23 years with the selective nonoperative management of blunt splenic injury in these patients. Medical record review identified nine patients with blunt splenic injury and infectious mononucleosis from 1978 to 2001, representing 3.3 per cent of our total trauma population with blunt splenic injury treated during that interval. Two patients underwent immediate splenectomy because of hemodynamic instability. Seven patients were admitted with the intent to treat nonoperatively. Five patients were successfully managed nonoperatively. Two patients failed nonoperative management and underwent splenectomy, one because of hemodynamic instability and one because of an infected splenic hematoma. Concurrent infectious mononucleosis does not preclude the successful nonoperative management of blunt splenic injury. This small subset of patients may be managed nonoperatively using the same criteria as for patients whose splenic injuries are not complicated by infectious mononucleosis.

Background Blunt traumatic cardiac rupture is rare. However, such cardiac ruptures carry a high mortality rate. This study reviews our experience treating blunt traumatic cardiac rupture. Methods This retrospective study included 21 patients who experienced blunt traumatic cardiac rupture from 1999 to 2015. Every patient underwent surgery. Several variables were compared between survivors and fatalities. Results Sixteen of the 21 patients survived, and 5 (24%) died. No instances of intraoperative mortality occurred. The most common cause of injury was a traffic accident (81%). The right atrium was the most common location of injury (43%). Ten of the 21 patients were suspected to have cardiac tamponade. Significant differences were found in preoperative creatine kinase–myocardial band (CK-MB) levels (p=0.042) and platelet counts (p= 0.004) between the survivors and fatalities. The patients who died had higher preoperative Glasgow Coma Scale scores (p=0.007), worse Trauma and Injury Severity Scores (p=0.007), and higher Injury Severity Scores (p=0.004) than those who survived. Conclusion We found that elevated CK-MB levels, a low platelet count, and multi-organ traumatic injury were prognostic factors predicting poor outcomes of blunt cardiac rupture. If a patient with blunt traumatic cardiac rupture has these factors, clinicians should be especially attentive and respond promptly in order to save the patient’s life. PMID:27965920

Most of the literature on surgical site infections following the surgical treatment of fractures of the ankle is based on small series of patients, focusing on diabetics or the elderly. None have described post-operative functional scores in those patients who develop an infection. We performed an age- and gender-matched case-control study to identify patient- and surgery-related risk factors for surgical site infection following open reduction and internal fixation of a fracture of the ankle. Logistic regression analysis was used to identify significant risk factors for infection and to calculate odds ratios (OR). Function was assessed using the Olerud and Molander Ankle Score. The incidence of infection was 4% (29/717) and 1.1% (8/717) were deep infections. The median ankle score was significantly lower in the infection group compared with the control group (60 vs 90, Mann-Whitney test p < 0.0001). Multivariate regression analysis showed that diabetes (OR = 15, p = 0.031), nursing home residence (OR = 12, p = 0.018) and Weber C fractures (OR = 4, p = 0.048) were significant risk factors for infection. A low incidence of infection following open reduction and internal fixation of fractures of the ankle was observed. Both superficial and deep infections result in lower functional scores.

Background Isolated small gut mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. These are always challenging to diagnose and pose a diagnostic dilemma. Objectives To study the pattern of small gut mesenteric injury by steering wheel blunt abdominal trauma in road traffic accidents in patients who had laparotomy. Patients and Methods A 10-year retrospective study was done to study isolated small gut mesentery injury. Results All patients who had isolated mesenteric small gut injury were males. Jejunal mesentery was involved in 13 whereas 4 had ileal mesentery injury. Tear were longitudinal or transverse. Conclusions Isolated small mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. Tears are either longitudinal or transverse. Suture repair is to be done. Delay in reaching hospital or reaching the diagnosis could lead to morbidity and mortality. Isolated mesenteric injury should be considered in any patient with blunt abdominal trauma from steering wheel injury with no evidence of any solid organ injury in unstable patients. PMID:24350106

Mortality has been shown to be high in patients after trauma nephrectomy (TN). However, there are little data regarding morbidity in survivors. The objective of this study was to determine the morbidity rates associated with TN with attention directed to renal failure (RF) and formation of intra-abdominal abscess (IAA). Patients who underwent TN over a 9-year period (1996 to 2004) were identified from the trauma registry. Records were reviewed for all complications after TN in patients surviving at least 48 hours. Eighty-nine patients were identified with TN; 61 per cent resulted after penetrating trauma. Overall mortality was 34 per cent. Seventy-one patients survived greater than 48 hours; 51 (72%) experienced at least one morbidity. There was no difference in morbidity rates between patients undergoing blunt trauma and those undergoing penetrating trama. Patients with morbidities were significantly older, more severely injured, and had higher mortality rates and longer hospital courses. Infectious complications were seen in 52 per cent, respiratory in 48 per cent, gastrointestinal in 30 per cent, coagulopathy in 25 per cent, and RF and IAA were each seen in 14 per cent of patients. Patients undergoing TN are severely injured with significant morbidity. The results from this study allow us to establish benchmarks to assess complication rates for patients who undergo TN, which can provide prognostic information and goals to improve patient outcomes.

The aim here was to present an unusual case of segmental clavicle fracture associated with ipsilateral rib fracture. Although the clavicle is very superficial, undetected cases of both types of fracture may occur, because these patients usually suffer multiple trauma. The case of a patient with a fracture of the diaphysis and lateral extremity of the clavicle is described: the patient was treated surgically and an excellent result was achieved. Similar cases in the literature are reviewed and their management is discussed. PMID:27047835

Abdominal blunt trauma represents the main cause of death in people of age less than 40 years; the liver injury occurs frequently, with an incidence varying from 3 to 10%. Isolated hepatic lesions are rare and in 77-90% of cases, lesions of other organs and viscera are involved. Right hepatic lobe is a frequent site of injury, because it is the more voluminous portion of liver parenchyma; posterior superior hepatic segments are proximal to fixed anatomical structures such as ribs and spine that may have an important role in determining of the lesion. The coronal ligaments' insertion in this parenchymal region augments the effect of acceleration-deceleration mechanism. Associated lesions usually are homolateral costal fractures, laceration or contusion of the inferior right pulmonary lobe, haemothorax, pneumothorax, renal and/or adrenal lesions. Traumatic lesions of left hepatic lobe are rare and usually associated with direct impact on the superior abdomen, such as in car-crash when the wheel causes a compressive effect on thorax and abdomen. Associated lesions to left hepatic lobe injuries correlated to this mechanism are: sternal fractures, pancreatic, myocardial, gastrointestinal tract injuries. Lesions of the caudal lobe are extremely rare, usually not isolated and noted with other large parenchymal lesions. The Institution of Specialized Trauma Centers and the technical progress in imaging methodology developed in the last years a great reduction of mortality. New diagnostic methodologies allow a reduction of negatives laparotomies and allow the possibility of conservative treatment of numerous traumatic lesions; however, therapy depends from imaging findings and clinical conditions of the patient. Computed tomography (CT) certainly presents a large impact on diagnosis and management of patients with lesions from blunt abdominal traumas. It is important to establish a prognostic criteria allowing decisions for conservative or surgical treatment; CT findings

External laryngeal trauma is a rare but potentially life-threatening situation in the acutely injured patient. Trauma mechanism and magnitude, maximum focus of the applied force, and patient related factors, such as age and ossification of the laryngeal cartilages influence the spectrum of observed injuries. Their correct diagnosis and prompt management are paramount in order to avoid patient death or long-term impairment of breathing, swallowing and speaking. The current review provides a comprehensive approach to the radiologic interpretation of imaging studies performed in patients with suspected laryngeal injury. It describes the key anatomic structures that are relevant in laryngeal trauma and discusses the clinical role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the acute emergency situation. The added value of two-dimensional multiplanar reconstructions (2D MPR), three-dimensional volume rendering (3D VR) and virtual endoscopy (VE) for the non-invasive evaluation of laryngeal injuries and for treatment planning is discussed. The clinical presentation, biomechanics of injury, diagnostic pitfalls and pearls, common and uncommon findings are reviewed with emphasis of fracture patterns, involvement of laryngeal joints, intra- and extralaryngeal soft tissue injuries, and complications seen in the acute emergency situation. The radiologic appearance of common and less common long-term sequelae, as well as treatment options are equally addressed.

Facial trauma is a significant cause of morbidity in the United States. Despite the large volume of trauma surgeries at most academic institutions, there is still controversy regarding management of many traumatic injuries. The literature lacks clear-cut best practices for most fractures. In orbital trauma, there is debate about the optimal timing of repair, preferred biomaterial to be used, and the utility of evaluation afterward with intraoperative computed tomographic scan. In repair of mandible fractures, there is debate regarding open versus closed reduction of subcondylar fractures, or alternatively, endoscopic repair.

In structural materials with both brittle and ductile phases, cracks often initiate within the brittle phase and propagate dynamically towards the ductile phase. The macroscale, quasistatic toughness of the material thus depends on the outcome of this microscale, dynamic process. Indeed, dynamics has been hypothesized to suppress dislocation emission, which may explain the occurrence of brittle transgranular fracture in mild steels at low temperatures (Lin et al., 1987). Here, crack tip blunting and cleavage under dynamic conditions are explored using continuum mechanics and molecular dynamics simulations. The focus is on two questions: (1) whether dynamics can affect the energy barriers for dislocation emission and cleavage, and (2) what happens in the dynamic "overloaded" situation, in which both processes are energetically possible. In either case, dynamics may shift the balance between brittle cleavage and ductile blunting, thereby affecting the intrinsic ductility of the material. To explore these effects in simulation, a novel interatomic potential is used for which the intrinsic ductility is tunable, and a novel simulation technique is employed, termed as a "dynamic cleavage test", in which cracks can be run dynamically at a prescribed energy release rate into a material. Both theory and simulation reveal, however, that the intrinsic ductility of a material is unaffected by dynamics. The energy barrier to dislocation emission appears to be identical in quasi-static and dynamic conditions, and, in the overloaded situation, ductile crack tip behavior ultimately prevails since a single emission event can blunt and arrest the crack, preventing further cleavage. Thus, dynamics cannot embrittle a ductile material, and the origin of brittle failure in certain alloys (e.g., mild steels) appears unrelated to dynamic effects at the crack tip.

Background: The contemplation for the salvage operations and the nonoperative treatment for the pediatric splenic injuries had increasingly been suggested as the standard case management. Objectives: The study was carried out to identify the risk factors, the presentations, the severities and outcome of the interventions of blunt splenic injuries in the children and adolescents. Materials and Methods: This retrospective review was carried out in a tertiary care hospital in Sikkim on the children and adolescents admitted with splenic injury from January 2005 to December 2009. Splenic injuries were graded with the American Association for the Surgery of Trauma Splenic Injury Scale followed by the operative and nonoperative managements (NOM). Results: Overall 147 cases with the abdominal trauma were diagnosed with splenic injury. Of them, males reported in higher numbers; three-fourths were adolescents with preponderance above 16 years of age. Majority of the cases [n=91(61.90%)] were due to fall from heights and others from road traffic accidents. Immediate surgical interventions was instituted in the hemodynamically unstable cases (n=87) NOM failed in 27 patients; of them eight cases underwent splenectomy, and 19 underwent surgical salvage; 33 were closely followed up by conservative approach with both clinical and CT criteria. Total number of cases in grade III and above was significantly higher than with lower grades of injury. Conclusions: In total 95(64.63%) of the cases were managed with total splenectomy; 19 cases in the initial nonsurgical group underwent salvage operation and 33 cases received NOM. PMID:21769209
The Chopart articular space was described by François Chopart (1743-1795) as a practical space for amputations in cases of distal foot necrosis. It corresponds to the limit between the anatomical hind-foot and the mid-foot. The bones involved are the talus and the calcaneus proximally, and the navicular and the cuboid distally. This space thus holds two functionally distinct entities, the anterior part of the coxa pedis (an essential functional joint) and the calcaneo-cuboidal joint,which can be considered to be an "adaptive joint" within a normal foot. Trauma to this region may cause fractures and/or dislocations and, in high energy trauma,compartment syndromes. Principles of treatment are immediate reduction of dislocations and realignment of the medial and lateral column of the foot in length and orientation. Open reduction and internal fixation of talus and navicular fractures are often indicated to restore the "coxa pedis". Open reconstruction or fusion in correct length of the calcaneo-cuboidal joint is occasionally indicated. Salvage procedures in malunions include navicular osteotomies and calcaneo-cuboidal bone block fusions. Treatment of joint destructions, especially involving the talo-navicular joint, include triple arthrodesis.

Background The consequence of the low rate of penetrating injuries in Europe and the increase in non-operative management of blunt trauma is a decrease in surgeons' confidence in managing traumatic injuries has led to the need for new didactic tools. The aim of this retrospective study was to present the Corso di Chirurgia del Politrauma (Trauma Surgery Course), developed as a model for teaching operative trauma techniques, and assess its efficacy. Method the two-day course consisted of theoretical lectures and practical experience on large-sized swine. Data of the first 126 participants were collected and analyzed. Results All of the 126 general surgeons who had participated in the course judged it to be an efficient model to improve knowledge about the surgical treatment of trauma. Conclusion A two-day course, focusing on trauma surgery, with lectures and life-like operation situations, represents a model for simulated training and can be useful to improve surgeons' confidence in managing trauma patients. Cooperation between organizers of similar initiatives would be beneficial and could lead to standardizing and improving such courses. PMID:16759403

Blunt, nonpenetrating injuries of the thoracic aorta are uncommon and associated with a high mortality rate within the first hour. Aortic injury is missed in 1-2% of patients that survive to hospital, and a chronic thoracic aortic aneurysm may subsequently form. We present a case in which a chronic thoracic aortic aneurysm was diagnosed 29 years following a significant motor vehicle accident. We discuss the epidemiology, presentation, and management of this uncommon consequence of blunt, nonpenetrating aortic injury. Our case illustrates an important clinical lesson; a past medical history of trauma should not be overlooked at any patient assessment. PMID:26351610

Abstract: Background: The global incidence of fatal head injuries as the result of assault is greater than the number of non-fatal cases. The important factors that determine the outcome in terms of survival of such head injury cases include the type of weapon used, type and site of skull fracture, intra cranial haemorrhage and the brain injury. The present study aims to highlight the role of skull fractures as an indirect indicator of force of impact and the intra cranial haemorrhage by a comparative study of assault victims with fatal and nonfatal head injuries. Methods: 91 head injury cases resulting from assault were studied in the Department of Forensic Medicine, IMS, BHU Varanasi over a period of 2 years from which 18 patients survived and 73 cases had a lethal outcome. Details of the fatal cases were obtained from the police inquest and an autopsy while examination of the surviving patients was done after obtaining an informed consent. The data so obtained were analyzed and presented in the study. Results: Assault with firearms often led to fatality whereas with assault involving blunt weapons the survival rate was higher. Multiple cranial bones were involved in 69.3% cases while comminuted fracture of the skull was common among the fatal cases. Fracture of the base of the skull was noted only in the fatal cases and a combination of subdural and subarachnoid haemorrhage was found in the majority of the fatal cases. Conclusions: The present study shows skull fractures to be an important indicator of severity of trauma in attacks to the head. Multiple bone fracture, comminuted fracture and base fractures may be considered as high risk factors in attempted homicide cases. PMID:21483205

Background: Trauma represents a global public health concern with an estimated 5 million deaths annually. Moreover, the incidence of blunt traumatic injuries (BTI) particularly road traffic accidents (RTAs) and workplace-related injuries are rising throughout the world-wide. Objectives: We aimed to review the epidemiology and prevention of BTI, in the Arab Middle East. Materials and Methods: A traditional narrative literature review was carried out using PubMed, MEDLINE and EMBASE search engines. We used the keywords “traumatic injuries”, “blunt” “epidemiology”, “Arab Middle East” between December 1972 and March 2013. Results: The most common mechanisms of BTI in our region are RTAs, falls from height, struck by heavy objects and pedestrian motor vehicle trauma crashes. The rate of RTA and occupational injuries are markedly increased in the region due to rapid industrial development, extreme climatic conditions and unfamiliar working environment. However, lack of reliable information on these unintentional injuries is mainly responsible for the underestimation of this trauma burden. This knowledge deficit shields the extent of the problem from policy makers, leading to continued fatalities. These preventable injuries in turn add to the overall financial burden on the society through loss of productivity and greater need of medical and welfare services. Conclusion: In the Arab Middle East, population-based studies on the incidence, mechanism of injury, prevention and outcome of BTI are not well-documented. Therefore, region-specific BTI studies would strengthen surveillance to better understand the burden of these injuries in the region. PMID:24812453
The authors present a study of the atomistic mechanisms of crack propagation along grain boundaries in metals and alloys. The failure behavior showing cleavage crack growth and/or crack-tip dislocation emission is demonstrated using atomistic simulations for an embedded-atom model. The simulations follow the quasi-equilibrium growth of a crack as the stress intensity applied increases. Dislocations emitted from crack tips normally blunt the crack and inhibit cleavage, inducing ductile behavior. When the emitted dislocations stay near the crack tip (sessile dislocations), they do blunt the crack but brittle cleavage can occur after the emission of a sufficient number of dislocations. The fracture process occurs as a combination of dislocation emission/micro-cleavage portions that are controlled by the local atomistic structure of the grain boundary. The grain boundary is shown to be a region where dislocation emission is easier, a mechanism that competes with the lower cohesive strength of the boundary region.

Fracture occurs in bone having less than normal elastic resistance without any violence. Numerous terms have been used to classify various types of fractures from low trauma events; "fragility fracture", "stress fracture", "insufficiency fracture", "fatigue fracture", "pathologic fracture", etc. The definitions of these terms and clinical characteristics of these fractures are discussed. Also state-of-the-art bone quality assessments; Finite element analysis of clinical CT scans, assessments of the Microdamage, and the Cross-links of Collagen are introduced in this review.

Massive hematoma of the corpus callosum caused by blunt head trauma is an extremely rare lesion. Most frequent traumatic lesions involve the corpus callosum are diffuse axonal injuries. They might be associated with small hemorrhagic foci in the hemispheric and brain stem white matter, intraventricular hemorrhages, subarachnoid hemorrhages, traumatic lesions of the septum pellucidum and fornix. Many cases of corpus callosum injury present with permanent disconnection syndrome. We present a case of a 32-year-old female suffered blunt head trauma resulted in massive corpus callosum hematoma which was managed non-surgically. The patient initially had a reduced conscious level and symptoms of disconnection syndrome, and significant recovery was observed at 6 months follow up.

Background The optimal timing of initiating low–molecular weight heparin (LMWH) in patients who have undergone nonoperative management (NOM) of blunt solid organ injuries (SOIs) remains controversial. We describe the safety of early initiation of chemical venous thromboembolism (VTE) prophylaxis among patients undergoing NOM of blunt SOIs. Methods We retrospectively studied severely injured adults who sustained blunt SOI without significant intracranial hemorrhage and underwent an initial NOM at a Canadian lead trauma hospital between 2010 and 2014. Safety was assessed based on failure of NOM, defined as the need for operative intervention, in patients who received early (< 48 h) or late LMWH (≥48 h, or early discharge [< 72 h] without LMWH). Results We included 162 patients in our analysis. Most were men (69%), and the average age was 42 ± 18 years. The median injury severity score was 17, and splenic injuries were most common (97 [60%], median grade 2), followed by liver (57 [35%], median grade 2) and kidney injuries (31 [19%], median grade 1). Combined injuries were present in 14% of patients. A total of 78 (48%) patients received early LMWH, while 84 (52%) received late LMWH. The groups differed only in percent of high-grade splenic injury (14% v. 32%). Overall 2% of patients failed NOM, none after receiving LMWH. Semielective angiography was performed in 23 (14%) patients. The overall rate of confirmed VTE on imaging was 1.9%. Conclusion Early initiation of medical thromboembolic prophylaxis appears safe in select patients with isolated SOI following blunt trauma. A prospective multicentre study is warranted. PMID:26820318

Background The initial nonoperative management (NOM) of blunt splenic injuries in hemodynamically stable patients is common. In soldiers who experience blunt splenic injuries with concomitant severe brain injury while on deployment, however, NOM may put the injured soldier at risk for secondary brain injury from prolonged hypotension. Methods We conducted a decision analysis using a Markov process to evaluate 2 strategies for managing hemodynamically stable patients with blunt splenic injuries and severe brain injury — immediate splenectomy and NOM — in the setting of a field hospital with surgical capability but no angiography capabilities. We considered the base case of a 40-year-old man with a life expectancy of 78 years who experienced blunt trauma resulting in a severe traumatic brain injury and an isolated splenic injury with an estimated failure rate of NOM of 19.6%. The primary outcome measured was life expectancy. We assumed that failure of NOM would occur in the setting of a prolonged casualty evacuation, where surgical capability was not present. Results Immediate splenectomy was the slightly more effective strategy, resulting in a very modest increase in overall survival compared with NOM. Immediate splenectomy yielded a survival benefit of only 0.4 years over NOM. Conclusion In terms of overall survival, we would not recommend splenectomy unless the estimated failure rate of NOM exceeded 20%, which corresponds to an American Association for the Surgery of Trauma grade III splenic injury. For military patients for whom angiography may not be available at the field hospital and who require prolonged evacuation, immediate splenectomy should be considered for grade III–V injuries in the presence of severe brain injury.

The aim of this retrospective study was to evaluate the epidemiology, treatment, and complications of frontal bone fractures associated, or not, with other facial fractures. This evaluation also sought to minimize the influence of the surgeon's skills and the preference for any rigid internal fixation system. The files from 3758 patients who attended the Oral and Maxillofacial Surgery Department of the School of Dentistry of Ribeirao Preto, University of Sao Paulo, from March 2004 to November 2011 and presented with facial trauma were scanned, and 52 files were chosen for the review. Eleven (21.15%) of these patients had pure fractures of the frontal bone, and trauma incidence was more prevalent in men (92.3%), whites (61.53%), and adults (50%). Despite the use of helmets at the moment of the trauma, motorcycle crashes were the most common etiological factor (32.69%). Fracture of the anterior wall of the frontal sinus with displacement was the main injury observed (54.9%), and the most common treatment was internal fixation with a plate and screws (45.09%). Postoperative complications were observed in 35.29% of the cases. The therapy applied was effective in handling this type of fracture, and the success rate was comparable to that reported in other published studies.

Introduction: Nonoperative management (NOM) has become the treatment of choice for hemodynamically stable patients with blunt splenic injury. Results of outcome after NOM are predominantly based on large-volume studies from level 1 trauma centers in the United States. This study was designed to assess the results of NOM in a relatively low-volume Dutch level 1 trauma center. Methods: An analysis of a prospective trauma registry was performed for a 6-year period before (period 1) and after the introduction and implementation of splenic artery embolization (SAE) (period 2). Primary outcome was the failure rate of initial treatment. Results: A total of 151 patients were reviewed. An increased use of SAE and a reduction of splenic operations during the second period was observed. Compared with period 1, the failure rate after observation in period 2 decreased from 25% to 10%. The failure rate after SAE in period 2 was 18%. The splenic salvage rate (SSR) after observation increased from 79% in the first period to 100% in the second period. During the second period, all patients with failure after observation were successfully treated with SAE. The SSR after SAE in periods 1 and 2 was respectively 100% and 86%. Conclusions: SAE of patients with blunt splenic injuries is associated with a reduction in splenic operations. The failure and splenic salvage rates in this current study were comparable with the results from large-volume studies of level 1 trauma centers. Nonoperative management also is feasible in a relatively low-volume level 1 trauma center outside the United States.

Background To decrease the burden of injuries it is essential to have an overview of trauma patterns and its management at regional trauma centers. Objectives The aim of this study was to investigate some patterns of trauma and trauma-related therapeutic interventions at our trauma center. Materials and Methods In a cross-sectional study, 19530 trauma cases admitted to the emergency department and hospital wards of Shohada University Hospital during 2007-2008 were assessed. Results Of the 19530 trauma cases, 14960(76.7%) were males. Mean (SD) of age was 31(19.9) years. The elderly aged 65 and above, comprised 10% (1953) of the participants; while 44 were infants. Falls and traffic injuries were the most common cause of injuries among trauma patients. Most of the mortalities were men comprising 74% of the 57 deaths. Reduction of fractures and dislocations were the most common types of operations among trauma patients. Conclusions Young men form the target group for possible interventions to decrease the burden of trauma following falls and traffic accidents. PMID:24350134

Outcome after traumatic brain injury (TBI) in the elderly has not been fully elucidated. The present retrospective observational study investigates the age-dependent outcome of patients suffering from severe isolated TBI with regard to operative and non-operative treatment. Data were prospectively collected in the TraumaRegister DGU. Anonymous datasets of 8629 patients with isolated severe blunt TBI (AISHead≥3, AISBody≤1) documented from 2002 to 2011 were analysed. Patients were grouped according to age: 1-17, 18-59, 60-69, 70-79 and ≥80 years. Cranial fractures (44.8%) and subdural haematomas (42.6%) were the most common TBIs. Independent from the type of TBI the group of patients with operative treatment declined with rising age. Subgroup analysis of patients with critical TBI (AISHead=5) revealed standardised mortality ratios (SMRs) of 0.81 (95% CI 0.75-0.87) in case of operative treatment (n=1201) and 1.13 (95% CI 1.09-1.18) in case of non-operative treatment (n=1096). All age groups ≥60 years showed significantly reduced SMRs in case of operative treatment. Across all age groups the group of patients with low/moderate disability according to the GOS (4 or 5 points) was higher in case of operative treatment. Results of this retrospective observational study have to be interpreted cautiously. However, good outcome after TBI with severe space-occupying haemorrhage is more frequent in patients with operative treatment across all age groups. Age alone should not be the reason for limited care or denial of operative intervention.

Background Up to 62% of patients report chronic pain at the injury site 6-12 months after blunt trauma, with pain from lower extremity fractures exceeding that from other sites. High pain intensity at time of injury is a risk factor for chronic pain, but it is not clear what patient characteristics influence the pain intensity level during the immediate hospitalization following injury. Aim The purpose of this pilot study was to determine the feasibility of collecting pain scores from medical records, to calculate pain trajectories, and to determine whether it is possible to examine patient characteristics by classifying them into those whose pain improved and those whose pain did not improve. Design This descriptive study retrospectively reviewed medical records of 18 randomly chosen patients admitted to an academic trauma center. Methods Patient characteristics and pain scores were collected form electronic and handwritten medical records. Results The pain trajectories calculated from routinely collected pain scores during the in-patient stay showed that for 44% of the patients the pain improved during the hospitalization, for 39% the pain remained the same and for 17% the pain worsened. Variables age, smoking, weight, abbreviated injury scores, length of hospital stay, mean pain score and opioid equianalgesic dose differed based on pain trajectory. Conclusion While patient characteristics differed based on pain trajectory, any significant effects seen from individual tests should be considered tentative, given the number of analyses conducted on this data set. However, feasibility and significance of conducting a larger study has been established. PMID:26545732

Introduction Pancreatic lesions are very infrequent after closed abdominal trauma (5% of cases) with a complication rate that affects 30–40% of patients, and a mortality rate that can reach 39%. In our experience, closed abdominal traumatisms occurring at typical popular horse-riding festivals in our region constitute a high risk of pancreatic trauma. The purpose of the present paper is to raise awareness about our experience in the diagnosis and treatment of pancreatic lesions secondary to closed abdominal traumatism. Presentation of case We present the clinical cases of two young patients who, after suffering blunt abdominal trauma secondary to the impact of a horse during the celebration of typical horse-riding festival, were diagnosed with pancreatic trauma type III. The treatment was surgical in both cases and consisted in performing a pancreaticogastric anastomosis with preservation of the distal pancreas and spleen. The postoperative period was uneventful and, at present, both patients are asymptomatic. Discussion Signs and symptoms caused by pancreatic lesion are unspecific and difficult to objectify. With some limitations CT is the imaging test of choice for diagnosis and staging in the acute phase. The Wirsung section is indication for surgical treatment. The most extended surgical procedure in these cases is the resection of pancreatic body, tail, and spleen. Conclusion The identification of a pancreatic injury after closed abdominal trauma requires a high suspicion based on the injury mechanism. A safer option may be the distal pancreatic preservation with pancreaticogastric anastomosis in grade III lesions with healthy pancreatic tissue. PMID:25744560

Trauma sustained during pregnancy can trigger uncertainty and anxiety for patient and orthopedic surgeon alike. In particular, orthopedic-related injuries raise concerns about preoperative, intraoperative, and postoperative care. In this article, we review common concerns about radiation exposure, leukemia, pain management, anticoagulation, and anesthesia. One finding is that radiation risk is minimal when obtaining x-rays for operative planning, provided that the cumulative dose is within 5 rad. We also address safety concerns about patient positioning and staff radiation exposure. In addition, we found that most anesthetics used in pregnancy are category C (ie, safe). Perioperative opioid use for pain management is recommended with little risk. Regarding anticoagulation, low-molecular-weight heparin and fondaparinux are the safest choices. Last, pregnancy is not a contraindication to operative management of pelvic and acetabular fractures.

Blunt traumatic abdominal aortic dissection is extremely rare and potentially deadly. We present the case of a 62-year-old man involved in a frontal car crash. After emergency undergoing laparotomy for bowel injuries, he was referred to our hospital due to acute ischemia of bilateral lower extremities on day 3 after the trauma. Computed tomography and aortography showed an aortobiiliac dissection with complete occlusion. This injury was successfully treated by endovascular treatment with 'kissing'-technique stent placement, which appears to be a safe, effective, and minimally invasive treatment.

Handball has developed into a much faster and high-impact sport over the past few years because of rule changes. Fast sports with close body contact are especially prone to orofacial trauma. Handball belongs to a category of sports with medium risk for dental trauma. Even so, there is only little literature on this subject. The aim of this study was to examine the prevalence and the type of injuries, especially the occurrence of orofacial trauma, habits of wearing mouthguards, as well as degree of familiarity with the tooth rescue box. For this purpose, 77.1% (n=542/703) of all top athletes and coaches from the two highest Swiss leagues (National League A and National League B), namely 507 professional players and 35 coaches, were personally interviewed using a standardized questionnaire. 19.7% (n=100/507) of the players experienced dental trauma in their handball careers, with 40.8% (n=51/125) crown fractures being the most frequent by far. In spite of the relatively high risk of lip or dental trauma, only 5.7% (n=29/507) of the players wear mouthguards. The results of this study show that dental trauma is common among Swiss handball players. In spite of the high risk of dental trauma, the mouthguard as prevention is not adequately known, and correct procedure following dental trauma is rarely known at all.
Traumatic injuries to the scrotum are uncommon but, when they do occur, frequently lead to serious complications. Early complications include testicular infarction, necrosis and abscess formation; in the longer-term trauma may result in testicular atrophy and subfertility. Early surgical intervention in patients with testicular rupture can significantly improve the clinical outcome and reduce the need for delayed orchidectomy. However, clinical examination of the scrotum following trauma is difficult and frequently inaccurate; this may result in incorrect triage of patients for surgical exploration. Scrotal ultrasound can reliably assess scrotal injuries and diagnose testicular rupture with a high level of accuracy. Additionally, ultrasound can provide important information regarding testicular perfusion, which can further inform decisions on surgical management. This article reviews the sonographic findings that may be encountered in patients with scrotal trauma, with an emphasis on blunt trauma. It describes the pivotal role that ultrasound can play in the accurate triage of these patients to surgical or conservative management. PMID:27433221

Upper extremity trauma can be penetrating or blunt in etiology. The close proximity of vein, artery and nerve makes for a complicated presentation and potentially complicated reconstruction. Orthopedic and neurologic injuries can cause the more long term disability of these patients, but vascular injuries are initially more life threatening. Control of vascular injuries can be particularly difficult due to anatomic issues in the upper extremities. The intervention carried significant morbidity until evolution to endovascular approaches occurred. By reconstructing the injury from a more ''remote'' access site, less concomitant injury to the extremity can be encountered. However, although control of vascular injuries may result in greater survival rates with less morbidity from the procedure, long term outcome remains dependent upon concomitant injuries. This review will encompass both vascular and neurologic injuries secondary to trauma to the upper extremity and outline some of the trends in management.

Hepatic trauma is a common cause for admissions in the Emergency Room. Currently, non-surgical management is the standard treatment in haemodynamically stable patients with a success rate of around 85 to 98%. This haemodynamic stability is the most important factor in selecting the appropriate patient. Adjuncts in non-surgical management are angioembolisation, image-guided drainage and endoscopic retrograde cholangiopancreatography. Failure in non-surgical management is relatively rare but potentially fatal, and needs to be recognised and aggressively treated as early as possible. The main cause of failure in non-surgical management is persistent haemorrhage. The aim of this paper is to describe current evidence and guidelines that support non-surgical management of liver injuries in blunt trauma.

Trauma care has evolved rapidly over the past decade. The benefits of operative fracture management in major trauma patients are well recognised. Concerns over early total care arose when applied broadly. The burden of additional surgical trauma could constitute a second hit, fuelling the inflammatory response and precipitating a decline into acute respiratory distress syndrome, sepsis and multiple organ dysfunction syndrome. Temporary external fixation aimed to deliver the benefits of fracture stabilisation without the risk of major surgery. This damage control orthopaedics approach was advocated for those in extremis and a poorly defined borderline group. An increasing understanding of the physiological response to major trauma means there is now a need to refine our treatment options. A number of large scale retrospective reviews indicate that early definitive fracture fixation is beneficial in the majority of major trauma patients. It is recommended that patients are selected appropriately on the basis of their response to resuscitation. The hope is that this approach (dubbed ‘safe definitive fracture surgery’ or ‘early appropriate care’) will herald an era when care is individualised for each patient and their circumstances. The novel Damage Control in Orthopaedic Trauma Surgery course at The Royal College of Surgeons of England aims to equip senior surgeons with the insights and mindset necessary to contribute to this key decision making process as well as also the technical skills to provide damage control interventions when needed, relying on the improved techniques of damage control resuscitation and advances in the understanding of early appropriate care.

Seatbelt associated blunt trauma to the rectum is a rare but well recognised injury. The exact mechanism of hollow visceral injury in blunt trauma is unclear. Stress and shear waves generated by abdominal compression may in part account for injury to gas containing structures. A ‘seatbelt sign’ (linear ecchymosis across the abdomen in the distribution of the lap belt) should raise the suspicion of hollow visceral injuries and can be more severe with disruption of the abdominal wall musculature. Three consecutive cases of rectal injury following blunt abdominal trauma, requiring emergency laparotomy and resection, are described. Lumbar spine injury occurred in one case and in the other two cases, there was injury to the iliac wing of the pelvis; all three cases sustained significant abdominal wall contusion or muscle disruption. Abdominal wall reconstruction and closure posed a particular challenge, requiring a multidisciplinary approach. The literature on this topic is reviewed and potential mechanisms of injury are discussed. PMID:26741660

Due to the prominent location of the nose, the most common facial traumas are nasal injuries. Although nasal traumas usually require staged intervention at a later period of time, in selected cases, primary reconstruction can be effective. A 20-year-old man who was referred from the emergency department with nasal trauma is presented. He reported a fall after feeling unsteady, which caused a direct nasal injury. Clinical examination revealed septal fracture with obstruction of the left nasal cavity and deformity of the nasal pyramid (inverted V deformity). The patient also had a complete dissection of the columella skin. Epistaxis was self-limited, and an open rhinoplasty procedure was decided because the trauma occurred 1 h before admission and there was no significant edema. Surgical intervention included septal reconstruction combined with restoration of the nasal pyramid and columella. One month later, the patient had patent nasal airways, and he was satisfied with the aesthetic result. PMID:22942663

Management of spinal trauma is a complex and rapidly evolving field. To optimize patient treatment algorithms, an understanding of and appreciation for current controversies and advancing technologies in the field of spinal trauma is necessary. Therefore, members of the AOSpine Knowledge Forum Trauma initiative used a modified Delphi method to compile a list of controversial issues and emerging technologies in the field of spinal trauma, and a list of the 14 most relevant topics was generated. A total of 45 440 manuscripts covering the breadth of spine and spinal trauma were initially identified. This broad search was then refined using the 14 categories felt to be most relevant to the current field of spinal trauma. The results were further pared down using inclusion criteria to select for the most relevant topics. The 8 remaining topics were classification schemes, treatment of vertebral compression fractures, treatment of burst fractures, timing of surgery in spinal trauma, hypothermia, the importance of global sagittal balance, lumbar subarachnoid drainage, and diffusion magnetic resonance imaging. These 8 topics were felt to be the most relevant, controversial, rapidly evolving, and most deserving of inclusion in this summary. In summary, despite recent advances, the field of spinal trauma has many ongoing points of controversy. We must continue to refine our ability to care for this patient population through education, research, and development. It is anticipated that the new AOSpine fracture classification system will assist with prospective research efforts.

Background The optimal time to initiate venous thromboembolism pharmacoprophylaxis after blunt abdominal solid organ injury is unknown. Methods Postinjury coagulation status was characterized using thromboelastography (TEG) in trauma patients with blunt abdominal solid organ injuries; TEG was divided into 12-hour intervals up to 72 hours. Results Forty-two of 304 patients (13.8%) identified underwent multiple postinjury thromboelastographic studies. Age (P = .45), gender (P = .45), and solid organ injury grade (P = .71) were similar between TEG and non-TEG patients. TEG patients had higher Injury Severity Scores compared with non-TEG patients (33.2 vs 18.3, respectively, P < .01). Among the TEG patients, the shear elastic modulus strength and maximum amplitude values began in the normal range within the first 12-hour interval after injury, increased linearly, and crossed into the hypercoagulable range at 48 hours (15.1 ± 1.9 Kd/cs and 57.6 ± 1.6 mm, respectively; P < .01, analysis of variance). Conclusions Patients sustaining blunt abdominal solid organ injuries transition to a hypercoagulable state approximately 48 hours after injury. In the absence of contraindications, pharmacoprophylaxis should be considered before this time for effective venous thromboembolism prevention. PMID:24112665

Videothoracoscopy represents a valid and useful approach in some patients with blunt chest trauma or penetrating thoracic injury. This technique has been validated for the treatment of clotted hemothorax or posttraumatic empyema, traumatic chylothorax, traumatic pneumothorax, in patients with hemodynamic stability. Moreover, it is probably the most reliable technique for the diagnosis of diaphragmatic injury. It is also useful for the extraction of intrathoracic projectiles and foreign bodies. This technique might be useful in hemodynamically stable patients with continued bleeding or for the exploration of patients with penetrating injury in the cardiac area, although straightforward data are lacking to confirm those indications. Thoracotomy or median sternotomy remain indicated in patients with hemodynamic instability or those that cannot tolerate lateral decubitus position or one-lung ventilation. Performing video-surgery in the trauma setting require expertise in both video-assisted thoracic surgery and chest trauma management. The contra-indications to videothoracoscopy and indications for converting the procedure to an open thoracotomy should be perfectly known by surgeons performing video-assisted thoracic surgery in the trauma setting. Conversion to thoracotomy or median sternotomy should be performed without delay whenever needed to avoid blood loss and achieve an adequate procedure.

Deep vein thrombosis (DVT) and pulmonary embolism (PE) are known collectively as venous thromboembolism (VTE). Venous thromboembolic events are common and potentially life-threatening complications following trauma with an incidence of 5 to 63%. DVT prophylaxis is essential in the management of trauma patients. Currently, the optimal VTE prophylaxis strategy for trauma patients is unknown. Traditionally, pelvic and lower extremity fractures, head injury, and prolonged immobilization have been considered risk factors for VTE; however it is unclear which combination of risk factors defines a high-risk group. Modalities available for trauma patient thromboprophylaxis are classified into pharmacologic anticoagulation, mechanical prophylaxis, and inferior vena cava (IVC) filters. The available pharmacologic agents include low-dose heparin (LDH), low molecular weight heparin (LMWH), and factor Xa inhibitors. Mechanical prophylaxis methods include graduated compression stockings (GCSs), pneumatic compression devices (PCDs), and A-V foot pumps. IVCs are traditionally used in high risk patients in whom pharmacological prophylaxis is contraindicated. Both EAST and ACCP guidelines recommend primary use of LMWHs in trauma patients; however there are still controversies regarding the definitive VTE prophylaxis in trauma patients. Large randomized prospective clinical studies would be required to provide level I evidence to define the optimal VTE prophylaxis in trauma patients. PMID:22084663

A 5-month-old, 13.5 kg, female Corriedale sheep was referred to the Veterinary Medicine Teaching Hospital, with a history of traumatic injury of the cervical spine followed by non-ambulatoric tetraparesis that occurred 2 weeks before being admitted to the hospital. At admission, malalignment of the cervical spine with the cranial part of the neck deviating to the right was noted. Neurological examinations identified the absence of postural reactions in both forelimbs, mildly decreased spinal reflexes, and normal reaction to pain perception tests. Radiography revealed malalignment of the cervical vertebrae with subluxations at C1-C2 and C2-C3, and a comminuted fracture of the caudal aspect of C2. The sheep was euthanized due to a presumed poor prognosis. Necropsy and histopathological findings confirmed injuries of the cervical spine from C1 to C3, which were consistent with the clinical finding of tetraparesis in this case. This paper presents a rare case of multiple subluxations of the cervical spine caused by blunt force trauma in a young sheep. These results highlight the importance of an astute clinical diagnosis for such an acute cervical spine trauma and the need for prompt surgical correction for similar cases in the future.

Blunted affect, also referred to as emotional blunting, is a prominent symptom of schizophrenia. Patients with blunted affect have difficulty in expressing their emotions. The work of Abrams and Taylor and their development of the Rating Scale for Emotional Blunting in the late 1970’s was an early indicator that blunted affect could indeed be assessed reliably. Since then, several new instruments assessing negative symptoms with subscales measuring blunted affect have been developed. In light of this, we aim to provide researchers and clinicians with a systematic review of the different instruments used to assess blunted affect by providing a comparison of the type, characteristics, administration and psychometric properties of these instruments. Studies reporting on the psychometric properties of instruments assessing blunted affect in patients with schizophrenia were included. Reviews and case studies were excluded. We reviewed 30 full-text articles and included 15 articles and 10 instruments in this systematic review. On average the instruments take 15–30 minutes to administer. We found that blunted affect items common across all instruments assess: gestures, facial expressions and vocal expressions. The CAINS Self-report Expression Subscale, had a low internal consistency score. This suggests that this sub-scale does not reliably assess patients’ self-reported blunted affect symptoms and is likely due to the nature of blunted affect. Instruments correlated minimally with instruments measuring positive symptoms and more importantly with depression suggesting that the instruments distinguish between seemingly similar symptoms.

We examined the impact of a trauma system on the survival of patients with a Trauma Score of 8 or less. We compared the observed survival with that predicted using a method that calculates the probability of survival (Ps) based on age, physiologic score, and anatomic severity of injury. Of 3394 patients triaged to trauma centers in a 12-month period, 283 (8.3%) had a Trauma Score of 8 or less. Sufficient data were available in 189 patients with blunt trauma to make the survival comparison. The Ps was 18%; the observed survival was 29%. Of 60 patients with penetrating trauma and complete data, the Ps was 8%; the observed survival was 20%. We attribute the improved survival to the integration of prehospital and hospital care and expeditious surgery.

A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial examination, the patient had no light perception in his right eye. Dilated ophthalmoscopy revealed massive subretinal hemorrhage with macular invasion and faint vitreous hemorrhage. We performed intravitreal injection of pure sulfur hexafluoride twice for displacement, after which visual acuity improved to 0.03. For persistent subretinal hemorrhage and suspicion of choroidal neovascularization (CNV), intravitreal bevacizumab (1.25 mg/0.05 mL) injection was administered. After 3 weeks, the visual acuity of his right eye recovered to 0.4. For early-stage choroidal rupture-induced subretinal hemorrhage and complications of suspected CNV, intravitreal injection of expandable gas and intraocular injection of antiangiogenesis drugs seem to be an effective treatment.

Pelvic fractures secondary to blunt trauma are associated with a significant mortality rate due to uncontrolled bleeding. Interventional radiology (IR) can play an important and central role in the management of such patients, offering definitive minimally invasive therapy and avoiding the need for high-risk surgery. Rapid access to whole-body computed tomography has been shown to improve survival in polytrauma patients and allows rapid diagnosis of vascular injury and assessment of suitability for endovascular therapy. IR can then target and treat the specific area of bleeding. Embolisation of bleeding pelvic arteries has been shown to be highly effective and should be the treatment of choice in this situation. The branches of the internal iliac artery (IIA) are usually involved, and these arteries are accessed by way of IIA catheterisation after abdominal aortography. Occasionally these arteries cannot be accessed by way of this conventional route because of recent IIA ligation carried out surgically in an attempt to stop the bleeding or because (in the rare situation we describe here) these vessels are excluded secondary to previous aortoiliac repair. In this situation, knowledge of pelvic arterial collateral artery pathways is important because these will continue to supply pelvic structures whilst making access to deep pelvic branches challenging. We describe a rare case, which has not been previously reported in the literature, in which successful embolisation of a bleeding pelvic artery was carried out by way of the collateral artery pathways.

The mandibular condyle region which protects the middle cranial fossa from facial and jaw traumas has an excellent osteomuscular structure. Condylar structures reduce or limit the force of trauma. Most importantly, the condylar neck is the weakest part of the mandible and is easily fractured without dislocation. Generally, this mechanism prevents condylar penetration into the middle cranial fossa; however, there are condylar penetration into the middle cranial fossa can be rarely. Glenoid fossa fractures without mandibular condylar fracture and dislocation can be made. In this article, we present two cases to assess the isolated glenoid fossa fractures of the temporal bone.

Avulsion injuries of the knee are common sequelae of significant trauma given the number of ligamentous and tendinous insertions around the joint. Commonly discussed avulsion fractures of the lateral knee include the Segond fracture of the lateral tibial plateau and the arcuate complex avulsion fracture of the fibular styloid process. A less common avulsion fracture is the iliotibial (IT) band avulsion fracture involving the anterolateral corner of the tibia (Gerdy's tubercle). It is crucial to identify IT band avulsion fractures because of the frequent associated internal derangements of the knee. This case report describes the imaging of an acute IT band avulsion fracture and compares these findings with other lateral knee avulsion fractures.

Objectives Isolated minor rib fractures (IMRFs) after blunt chest traumas are commonly observed in emergency departments. However, the relationship between IMRFs and subsequent pneumonia remains controversial. This nationwide cohort study investigated the association between IMRFs and the risk of pneumonia in patients with blunt chest traumas. Design Nationwide population-based cohort study. Setting Patients with IMRFs were identified between 2010 and 2011 from the Taiwan National Health Insurance Research Database. Participants Non-traumatic patients were matched through 1:8 propensity-score matching according to age, sex, and comorbidities (namely diabetes, hypertension, cardiovascular disease, asthma and chronic obstructive pulmonary disease (COPD)) with the comparison cohort. We estimated the adjusted HRs (aHRs) by using the Cox proportional hazard model. A total of 709 patients with IMRFs and 5672 non-traumatic patients were included. Main outcome measure The primary end point was the occurrence of pneumonia within 30 days. Results The incidence of pneumonia following IMRFs was 1.6% (11/709). The aHR for the risk of pneumonia after IMRFs was 8.94 (95% CI=3.79 to 21.09, p<0.001). Furthermore, old age (≥65 years; aHR=5.60, 95% CI 1.97 to 15.89, p<0.001) and COPD (aHR=5.41, 95% CI 1.02 to 3.59, p<0.001) were risk factors for pneumonia following IMRFs. In the IMRF group, presence of single or two isolated rib fractures was associated with an increased risk of pneumonia with aHRs of 3.97 (95% CI 1.09 to 14.44, p<0.001) and 17.13 (95% CI 6.66 to 44.04, p<0.001), respectively. Conclusions Although the incidence of pneumonia following IMRFs is low, patients with two isolated rib fractures were particularly susceptible to pneumonia. Physicians should focus on this complication, particularly in elderly patients and those with COPD. PMID:28087547

Background : The liver is the most injured organ in abdominal trauma. Currently, the treatment in most cases is non-operative, but surgery may be necessary in severe abdominal trauma with blunt liver damage, especially those that cause uncontrollable bleeding. Despite the damage control approaches in order to achieve hemodynamic stability, many patients develop hypovolemic shock, acute liver failure, multiple organ failure and death. In this context, liver transplantation appears as the lifesaving last resource Aim : Analyze the use of liver transplantation as a treatment option for severe liver trauma. Methods : Were reviewed 14 articles in the PubMed, Medline and Lilacs databases, selected between 2008-2014 and 10 for this study. Results : Were identified 46 cases undergoing liver transplant after liver trauma; the main trauma mechanism was closed/blunt abdominal trauma in 83%, and severe trauma (>grade IV) in 81 %. The transplant can be done, in this context, performing one-stage procedure (damaged organ removed with immediate transplantation), used in 72% of cases. When the two-stage approach is performed, end-to-side temporary portacaval shunt is provided, until new organ becomes available to be transplanted. If two different periods are considered - from 1980 to 2000 and from 2000 to 2014 - the survival rate increased significantly, from 48% to 76%, while the mortality decreased from 52% to 24%. Conclusion : Despite with quite restricted indications, liver transplantation in hepatic injury is a therapeutic modality viable and feasible today, and can be used in cases when other therapeutic modalities in short and long term, do not provide the patient survival chances.

Background Blunt main stem bronchial injuries are rare but potentially life-threatening injuries in clinical. The aim of this study was to sum up the experience on diagnosis and treatment of blunt main stem bronchial injuries. Methods This report retrospective1y analyzed eight cases of main stem bronchial injuries induced by blunt chest trauma between 2013 and 2016 in Tangdu Hospital, Fourth Military Medical University. Results There were eight patients, including four men and four women. The definitive diagnosis was confirmed by fibrobronchoscopy. Mean time between injury and treatment in our hospital was 4.25 days (range, 1–12 days). Mean length of airway tear was 1.04 cm (range, 0.5–2 cm). In four patients there was an injury to the left main stem bronchus, in three patients to the right main stem bronchus and in one patient to the ambilateral main stem bronchus. Emergent operation was performed in two patients and elective operation in six patients. End to end bronchial anastomosis was performed via right thoracotomy in two patients and via left thoracotomy in three patients, and primary repair was performed via right thoracotomy in two patients and via left thoracotomy in the remaining one patient. There was no death in this group. Seven patients had no complications and were able to take part in normal activities. One patient suffered from anastomotic stricture after operation was healed by granulation tissue resection and cryotherapy under fibrobronchoscopy. Conclusions Fibrobronchoscopy is able to define the blunt main stem bronchial injuries precisely and surgical approach is the preferred method for patients with these life-threatening complications.

Background: In Peru, 11% of deaths are due to trauma. Iquitos is a large underserved Peruvian city isolated from central resources by its geography. Our objective was to implement a locally driven trauma registry to sustainably improve trauma healthcare in this region. Methods: All trauma patients presenting to the main regional referral hospital were included in the trauma registry. A pilot study retrospectively analyzed data from the first two months after implementation. Results: From March to April 2013, 572 trauma patients were entered into the database. Average age was 26.9 years. Ten percent of patients presented more than 24 hours after injury. Most common mechanisms of injury were falls (25.5%), motor vehicle collisions (23.3%), and blunt assault (10.5%). Interim analysis revealed that 99% of patients were entered into the database. However, documentation of vital signs was poor: 42% of patients had temperature, 26% had oxygen saturation documented. After reporting to registry staff, a significant increase in temperature (42 to 97%, P < 0.001) and oxygen saturation (26 to 92%, P < 0.001) documentation was observed. Conclusion: A trauma registry is possible to implement in a resource-poor setting. Future efforts will focus on analysis of data to enhance prevention and treatment of injuries in Iquitos.

Background The management of pancreatic trauma is complex. The aim of this study was to report our experience in the management of pancreatic trauma. Methods All patients hospitalized between 2005 and 2013 for pancreatic trauma were included. Traumatic injuries of the pancreas were classified according to the American Association for Surgery of Trauma (AAST) in five grades. Mortality and morbidity were analyzed. Results A total of 30 patients were analyzed (mean age: 38±17 years). Nineteen (63%) patients had a blunt trauma and 12 (40%) had pancreatic injury ≥ grade 3. Fifteen patients underwent exploratory laparotomy and the other 15 patients had nonoperative management (NOM). Four (13%) patients had a partial pancreatectomy [distal pancreatectomy (n=3) and pancreaticoduodenectomy (n=1)]. Overall, in hospital mortality was 20% (n=6). Postoperative mortality was 27% (n=4/15). Mortality of NOM group was 13% (n=2/15) in both cases death was due to severe head injury. Among the patients who underwent NOM, three patients had injury ≥ grade 3, one patient had a stent placement in the pancreatic duct and two patients underwent endoscopic drainage of a pancreatic pseudocyst. Conclusions Operative management of pancreatic trauma leads to a higher mortality. This must not be necessarily related to the pancreas injury alone but also to the associated injuries including liver, spleen and vascular trauma which may cause impaired outcome more than pancreas injury.

Following complex foot injuries (incidence up to 52 %) in the multiply-injured patient the ultimate goal remains the same as for all significant foot injuries: the restoration of a painless, stable and plantigrade foot to avoid corrective procedures with moderate results. In the case of a complex trauma of the foot (5 point-score) - e. g. a crush injury - primary amputation in the multiply-injured patient (PTS 3-4) is indicated. Limb salvage (PTS 1-2) depends on the intraoperative aspect during the second look (within 24-48 hours after injury): the debridement has to be radical, the selection of amputation level should be at the most distal point compatible with tissue viability and wound healing. A free tissue transfer should be done early if necessary. Single lesions presenting with a compartment syndrome need an immediate dorsal fasciotomy, in the case of a multiply-injured patient as soon as possible. Open fractures are reduced following radical debridement and temporarily stabilized with K-wires and/or tibiotarsal transfixation with an external fixateur until the definitive ORIF. Dislocation-fractures of the talus type 3 and 4 according to Hawkins' classification need open reduction and internal fixation by screws (titan). Open fractures of the calcaneus are stabilized temporarily by a medial external fixateur after debridement until the definitive treatment. If there is a compartment syndrome an immediate dermatofasciotomy is essential. Like closed, calcanear fractures in multiply-injured patients dislocation-fractures of the Chopart's joint need immediate open reduction only if it is an open fracture or associated with a compartment syndrome. The incidence of a compartment syndrome in the case of dislocation fractures of the Lisfranc's joint is high and therefore a dorsal dermatofasciotomy without delay is critical. Open reduction and internal fixation are achieved either by 1.8 mm K-wires or 3.5 mm cortical screws. To avoid further soft tissue damage a

Trauma may cause irreversible tissue damage and loss of function despite current best practice. Healing is dependent both on the nature of the injury and the intrinsic biological capacity of those tissues for healing. Preclinical research has highlighted stem cell therapy as a potential avenue for improving outcomes for injuries with poor healing capacity. Additionally, trauma activates the immune system and alters stem cell behaviour. This paper reviews the current literature on stem cells and its relevance to trauma care. Emphasis is placed on understanding how stem cells respond to trauma and pertinent mechanisms that can be utilised to promote tissue healing. Research involving notable difficulties in trauma care such as fracture non-union, cartilage damage and trauma induced inflammation is discussed further. PMID:28272352

This is a retrospective review to determine demographics, presentation and injury characteristics of trauma deaths at Howard University Hospital over an 1-year period (1994-2005) and to make recommendations for education and prevention in the community based on our findings. Data was obtained from the Howard University Hospital trauma registry. From the study period 1994-2005, there was a total of 365 trauma deaths. The injuries sustained were mainly intentional, which accounted for almost 75% of cases--the majority of deaths being due to penetrating injuries. There was an almost two-fold increase in trauma deaths on Saturdays compared to the rest of the week. The demographics of our study population were similar to those reported in the trauma literature. These were younger patients and predominantly male. Unique to our population was the overwhelming predominance of African-American patients (90%). With these unique features, injury prevention would be better served focusing on social and community prevention and education rather than the usual methods of blunt-trauma prevention--e.g., pedestrian- and motor-vehicle-oriented policies, which may be more beneficial in other trauma systems.

Blunt and penetrating cardiovascular (CV) injuries are associated with a high morbidity and mortality. Rapid detection of these injuries in trauma is critical for patient survival. The advent of multi-detector computed tomography (MDCT) has led to increased detection of CV injuries during rapid comprehensive scanning of stabilized major trauma patients. MDCT has the ability to acquire images with a higher temporal and spatial resolution, as well as the capability to create multiplanar reformats. This pictorial review illustrates several common and life-threatening traumatic CV injuries from a regional trauma center.

Nasal trauma plays a large and important role in the field of craniofacial trauma. The resulting aesthetic, structural, and functional sequelae associated with these injuries necessitate a thorough understanding of the topic. This includes an appreciation for the unique anatomic features of the region, the important aspects of the initial history and examination, nasal injury classification, and subsequent treatment timing and options. While a large body of literature has accumulated on the topic, the purpose of this article is to focus on both clinically relevant information and pearls of management. Additionally, age-specific concerns, secondary procedures, and nasal fracture grafting, will be addressed as well. PMID:22550458

A numerical study was conducted to investigate the effects of blunt leading edges on the viscous flow field around a hypersonic vehicle such as the proposed National Aero-Space Plane. Attention is focused on two specific regions of the flow field. In the first region, effects of nose bluntness on the forebody flow field are investigated. The second region of the flow considered is around the leading edges of the scramjet inlet. In this region, the interaction of the forebody shock with the shock produced by the blunt leading edges of the inlet compression surfaces is analyzed. Analysis of these flow regions is required to accurately predict the overall flow field as well as to get necessary information on localized zones of high pressure and intense heating. The results for the forebody flow field are discussed first, followed by the results for the shock interaction in the inlet leading edge region.

A group of 191 cases of emergency tube thoracostomy for acute trauma reviewed retrospectively from March 1993 to March 1998 is reported. Of this group 169 were men and 22 were women. Their ages ranged from 16 to 73 years. The causes were as follows: 89 cases (46%) road accident; 33 cases (17%) accidental trauma; 33 cases (17%) someone else violence (assault, gunshot or stab wound); 15 cases (8%) work accident; 11 cases (6%) domestic accident and 5 cases (3%) iatrogenic trauma. In 32 patients a diagnosis of pneumothorax was made (2 tension, 11 for penetrating chest injuries, 19 after blunt trauma). In 2 cases of tension pneumothorax and in 3 cases of open pneumothorax a chest tube (24-28 Fr) in the third space in the mid-clavicular line was introduced. In the other patients it was decided to place a chest tube in the mid-axillary line in the fifth intercostal space to drain pneumothorax. Only in 7 cases suction was necessary. Fifty-four hemothorax (3 bilateral) were treated in 11 cases using thoracentesis, while the remaining cases were treated using the insertion of multiple drainage holes in the intercostal space (fifth in the mid-axillary line directed inferiorly and posteriorly). One hundred and three were the cases of hemopneumothorax: 24 of them received 2 chest tubes, the first (20-26 Fr) apically in the second intercostal space in the mid-clavicular line, the second (32-38 Fr) in the fifth intercostal space in the mid-axillary line. All the other cases were treated using a single thoracostomy. In 14 cases suction was applied. Two cases of chylothorax resolved by a large tube positioned in the chest (fifth intercostal space in the mid-axillary line) with a constant negative pressure were also observed. Duration of tube drainage ranged from 4 and 18 days, with an average of 11 days. Five infections of thoracostomy site and 1 empyema resolved by rethoracotomy were observed. Moreover, there were 3 complications: 2 subcutaneous placements and 1 little laceration

Pelvic fractures may occur together with hip fractures as a result of low energy trauma. It is unclear whether they do require special attention. There are conflicting results in the literature about the prevalence of both concomitant hip and pelvic fractures as well as exclusive pelvic fractures. It has been reported that hip fractures and obturator ring fractures are mutually exclusive. To retrospectively analyze the prevalence of exclusively pelvic as well as concomitant hip and pelvic fractures in patients examined with MRI after low-energy trauma in elderly. During 9 years, 316 elderly patients had been examined with MRI for suspected or occult hip fracture after a fall. A fracture was diagnosed when MRI showed focal signal abnormalities in the subcortical bone marrow, with or without disruption of adjacent cortices. One observer reviewed all studies. A second observer verified all studies with hip fractures. Follow-up was available for all but two patients that died prior to hip surgery. The prevalence of concomitant pelvic and femoral neck or trochanteric fractures was statistically compared using chi-squared test for categorical variables. Hip fractures were found in 161 (51 %) patients of which 29 (9 %) had concomitant pelvic fractures. There were exclusively pelvic fractures in 82 (26 %) patients of which 65 (79 %) were on the traumatized side only. In 73 patients, there were no fractures. Occult or suspected hip fractures are not infrequently associated with pelvic fractures. Exclusively pelvic fractures are not uncommon.

Insufficiency fracture of the calcaneus is a rare entity. In the absence of trauma, evaluating a painful ankle in an elderly patient can be difficult and also it might be overlook the insufficiency fracture. We experienced a case of insufficiency calcaneus fracture that occurred after ipsilateral total knee arthroplasty. Here, we report our case with a review of literatures. PMID:26981521

Introduction Advanced Trauma Life Support (ATLS) protocols provide a common approach for trauma resuscitations. This was a quality review assessing compliance with ATLS protocols at a Level I trauma center; specifically whether the presence or absence of a trauma team leader (TTL) influenced adherence. Methods This retrospective study was conducted on adult major trauma patients with acute injuries over a one-year period in a Level I Canadian trauma center. Data were collected from the Alberta Trauma Registry, and adherence to ATLS protocols was determined by chart review. Results The study identified 508 patients with a mean Injury Severity Score of 24.5 (SD 10.7), mean age 39.7 (SD 17.6), 73.8% were male and 91.9% were involved in blunt trauma. The overall compliance rate was 81.8% for primary survey and 75% for secondary survey. The TTL group compared to non-TTL group was more likely to complete the primary survey (90.9% vs. 81.8%, p = 0.003), and the secondary survey (100% vs. 75%, p = 0.004). The TTL group was more likely than the non-TTL group to complete the following tasks: insertion of two large bore IVs (68.2% vs. 57.7%, p = 0.014), digital rectal exam (64.6% vs. 54.7%, p = 0.023), and head to toe exam (77% vs. 67.1%, p = 0.013). Mean times from emergency department arrival to diagnostic imaging were also significantly shorter in the TTL group compared to the non-TTL group, including times to pelvis xray (mean 68min vs. 107min, p = 0.007), CT chest (mean 133min vs. 172min, p = 0.005), and CT abdomen and pelvis (mean 136min vs. 173min, p = 0.013). Readmission rates were not significantly different between the TTL and non-TTL groups (3.5% vs. 4.5%, p = 0.642). Conclusions While many studies have demonstrated the effectiveness of trauma systems on outcomes, few have explored the direct influence of the TTL on ATLS compliance. This study demonstrated that TTL involvement during resuscitations was associated with improved

The bridging procedures discussed provide an accurate engineering method for predicting rarefied transitional aerodynamics of spherically-blunted cone entry vehicles. The single-point procedure offers a way to improve the bridging procedures while minimizing the computational effort. However, the accuracy of these procedures ultimately depends on accurate knowledge of the aerodynamics in the free-molecular and continuum limits. The excellent agreement shown for DSMC predictions and bridging relations with the Viking flight data in transitional regime enhance the coincidence in these procedures.

Thoracolumbar spine fractures are common injuries that can result in significant disability, deformity and neurological deficit. Controversies exist regarding the appropriate radiological investigations, the indications for surgical management and the timing, approach and type of surgery. This review provides an overview of the epidemiology, biomechanical principles, radiological and clinical evaluation, classification and management principles. Literature review of all relevant articles published in PubMed covering thoracolumbar spine fractures with or without neurologic deficit was performed. The search terms used were thoracolumbar, thoracic, lumbar, fracture, trauma and management. All relevant articles and abstracts covering thoracolumbar spine fractures with and without neurologic deficit were reviewed. Biomechanically the thoracolumbar spine is predisposed to a higher incidence of spinal injuries. Computed tomography provides adequate bony detail for assessing spinal stability while magnetic resonance imaging shows injuries to soft tissues (posterior ligamentous complex [PLC]) and neurological structures. Different classification systems exist and the most recent is the AO spine knowledge forum classification of thoracolumbar trauma. Treatment includes both nonoperative and operative methods and selected based on the degree of bony injury, neurological involvement, presence of associated injuries and the integrity of the PLC. Significant advances in imaging have helped in the better understanding of thoracolumbar fractures, including information on canal morphology and injury to soft tissue structures. The ideal classification that is simple, comprehensive and guides management is still elusive. Involvement of three columns, progressive neurological deficit, significant kyphosis and canal compromise with neurological deficit are accepted indications for surgical stabilization through anterior, posterior or combined approaches.

Patients with maxillofacial trauma require a careful evaluation due to the anatomical proximity of the maxillofacial region to the head and neck. Facial injuries can range from soft-tissue lacerations and nondisplaced nasal fractures to severe, complex fractures, eye injuries, and possible brain injury. Though the Advanced Trauma Life Support (ATLS) guidelines provide a framework for the management of trauma patients, they do not provide a detailed reference for many subtle or complex facial injuries. This issue adds a more comprehensive and systematic approach to the secondary survey of the maxillofacial area and emergency department management of injuries to the face. In addition to an overall review of maxillofacial trauma pathophysiology, associated injuries, and physical examination, this review will also discuss relevant imaging, treatment, and disposition plans.

The unique ability of magnetic resonance (MR) imaging to visualize injuries of bone, cartilage, bone marrow, and supporting soft tissue structure makes it ideally suited for the evaluation of musculoskeletal trauma. Magnetic resonance imaging also offers exquisitely detailed anatomical information on the musculoskeletal system. The widespread availability of MR imaging and the constantly improving technology make it the imaging modality of choice for the patients with a musculoskeletal trauma. This review discusses the role and applications of MR imaging for musculoskeletal trauma. It covers traumatic conditions of the musculoskeletal system, including hemarthrosis, lipohemarthrosis, stress fracture, occult fractures, cartilage injuries, the muscle and tendon trauma, avulsion injuries, extensor mechanism injuries, and traumatic conditions of joints.

For 4 years we followed a group of football players in the youth division of a professional club, ranging in age from 9 to 19 years, and analyzed the major injuries, i.e., those which required them to be sidelined for at least 4 weeks. We observed 23 sprains, 16 fractures, 16 cases of osteochondrosis, 7 muscle lesions, 6 cases of groin pain (athletic pubalgia), and 4 tendonopathies. The most frequent sites were the knee (n=30) and the ankle (n=11); the trauma factor was predominant (65.2%) with respect to overuse; noncontact traumas were more numerous (63.8%) than those resulting from contrast. Of a total 72 cases 8 regarded goalkeepers, and the remaining 64 cases were distributed among the other positions. As regards the age categories we detected a prevalence of osteochondrosis, traumatic detachments, and some fractures in the younger players, while in the older athletes we observed more sprains, muscle lesions, and tendonopathies.

In this chapter recent activity in real-gas database definition and code validation will be summarized. In the Phase I report of the Working Group (WG) 181, aerothermodynamic problems were classified, for purpose of discussion, into seven types: aerodynamic parameters, viscous/shock interaction, boundary-layer transition, forebody-heating/heat-transfer, radiation and ablation, lee and base-region flow, and low-density flow. Several of these problem types were the subject of various chapters of the Phase 1 report describing real-gas effects and ground test facility issues. In this chapter some background and objectives outlined in the real-Gas effects Chapter V of the Phase 1 report will be reviewed. The results of the blunt cone test campaign developed under the auspices of the WG18 activity to study real-gas phenomena will be summarized, including the experimental and computational programs, issues and questions, and recommendations. Further, recent progress in other real-gas areas beyond the blunt cone test campaign will be discussed. Finally, a summary in which the present status of our understanding of real-gas issues will be presented.
H. Julian Allen is best known for his 'Blunt Body Theory' of aerodynamics, a design technique for alleviating the severe re-entry heating problem which was then delaying the development of ballistic missiles. His findings revolutionized the fundamental design of ballistic missle re-entry shapes. Subsequently, applied research led to applications of the 'blunt' shape to ballistic missles and spacecraft which were intended to re-enter the Earth's atmosphere. This application led to the design of ablative heat shields that protected the Mercury, Gemini and Apollo astronauts as their space capsules re- entered the Earth's atmosphere. 'Harvey' Allen as he was called by most, was not only a brilliant scientist and aeronautical engineer but was also admired for his kindness, thoughtfulness and sense of humor. Among his many other accomplishments, Harvey Allen served as Center Director of the NASA Ames Research Center from 1965 to 1969. He died of a heart attack on January 29, 1977 at the age of 66.

The incidence of ankle fractures (AFs) in the elderly is rising due to the increase in life expectancy. Rather than directly related to osteoporosis, AFs are a predictor of osteoporotic fractures in other sites. In women AFs are associated with weight and BMI. AFs are difficult to categorize; therapeutic options are non-operative treatment with plaster casts or surgical treatment with Kirschner's wires, plates and screws. The choice of treatment should be based not only on the fracture type but also on the local and general comorbidity of the patient. Considering the new evidence that postmenopausal women with AFs have disrupted microarchitecture and decreased stiffness of the bone compared with women with no fracture history, in our opinion low-trauma AFs should be considered in a similar way to the other classical osteoporotic fractures.

A ruptured spleen caused by blunt abdominal injury is often treated by splenectomy. In view of the gravity of the 'postsplenectomy syndrome,' a conservative approach has been increasingly used. We present the case of a 29-year-old man with a Grade III splenic lesion for a blunt abdominal trauma after a car accident. We performed a partial splenectomy of the upper pole using GIA-Stapler. A supplemental haemostasis of the stapled line was successfully achieved by the application of FloSeal matrix haemostatic agent. The splenic remnant was fixed into the left-upper quadrant using human fibrin glue.

Fractures are an important entity to consider in pediatric patients. There are certain diseases in which bones fracture with a minimal trauma. Pycnodysostosis is an autosomal recessive unusual type of cráneo metaphyseal dysplasia, that presents frequently as fracture in a pathological bone. A 9 year old caucasian female, diagnosed with pycnodysostosis, was admitted with a right femur fracture as a result of a low energy trauma. Radiographic studies showed bilateral femur fractures, proximal fracture and non-union in antecurvatum of the left tibia. Pycnodysostosis is a rare disease, generally diagnosed at an early age by growth restriction, frequent fractures or fractures with low energy trauma. Therapy alternatives are limited, and no permanent cure has been developed. If a patient has dysmorphic facial features and fractures in a pathological bone, it is important to suspect bone dysplasia, such as pycnodysostosis and its differential diagnoses.

Aim: Dental injuries, especially luxation and avulsion, are common. Dental trauma can cause alveolar bone fracture that can lead to tooth loss and malocclusion. Single tooth alveolar bone fractures are difficult to identify unless it protrudes through the overlying mucosa and can be visualized. Pain, malocclusion, and tooth mobility provide signs of suspected alveolar bone fractures. Integrity of the proximate alveolar bone should be examined for fractures where avulsion, luxation, or other tooth trauma is detected. Any suggestion of alveolar fractures should be further investigated with an appropriate radiograph. Summary: This case report shows a pathognomonic sign that detects and diagnosis single tooth alveolar bone fractures, i.e., a localized hematoma crossing the attached gingiva from the free gingival margin to the vestibular mucosa. This should serve as a warning for localized alveolar bone fracture. A visualized hematoma and gentle, careful palpation may help detect covered fractures when the overlying mucosa is not perforated.

The word 'trauma' describes the disease entity resulting from physical injury. Trauma is one of the leading causes of death worldwide and deaths due to injury look set to increase. As early as the 1970s, it became evident that centralisation of resources and expertise could reduce the mortality rate from serious injury and that organisation of trauma care delivery into formal systems could improve outcome further. Internationally, trauma systems have evolved in various forms, with widespread reports of mortality and functional outcome benefits when major trauma management is delivered in this way. The management of major trauma in England is currently undergoing significant change. The London Trauma System began operating in April 2010 and others throughout England became operational this year. Similar systems exist internationally and continue to be developed. Anaesthetists have been and continue to be involved with all levels of trauma care delivery, from the provision of pre-hospital trauma and retrieval teams, through to chronic pain management and rehabilitation of patients back into society. This review examines the international development of major trauma care delivery and the components of a modern trauma system.

Blunt abdominal aortic injury is an uncommon traumatic finding. In the past, treatment options have traditionally consisted of open operative repair; however, the development of endovascular surgery has created new interventional possibilities. This case is presented to demonstrate the applications of endovascular abdominal aortic repair for a blunt traumatic injury. PMID:23730142

Context: Sport-related spleen and liver injuries pose a challenge for the physician. Although rare, these injuries can have serious and even life-threatening outcomes if not accurately diagnosed and managed in a timely fashion. Currently, there are no evidence-based guidelines on duration and intensity of restricted activity and return to play after spleen and liver injury. In addition, there is controversy on follow-up imaging after injury. Evidence Acquisition: PubMed was searched using the terms splenic or spleen and trauma and hepatic or liver and trauma from 1980 to 2013. The citations from sentinel papers were also reviewed. Study Design: Clinical review. Level of Evidence: Level 3. Results: Ultrasound is ideal in the unstable athlete. Nonoperative management of blunt splenic and hepatic injuries is recommended for hemodynamically stable patients regardless of injury grade, patient age, or presence of associated injuries. Follow-up imaging is not routinely recommended unless clinically indicated. Athletes may engage in light activity for the first 3 months after injury and then gradual return to unrestricted activity as tolerated. High-level athletes may choose splenectomy or serial imaging for faster return to play. Conclusion: Intravenous contrast-enhanced computed tomography is the diagnostic imaging modality of choice in stable athletes with blunt abdominal trauma. Strength-of-Recommendation Taxonomy: C.

A review of splenic injuries at Cincinnati Children's Hospital Medical Center from July 1978 to June 1980 revealed this form of injury in 29 patients. Treatment without surgery was successful in 21 patients. Seven patients required operation. One patient died shortly after admission of severe associated injuries. All patients admitted with blunt abdominal trauma were initially treated conservatively. If the clinical state improved, after transfusions if necessary, or remained stable and there were no objective signs of further blood loss, conservative therapy was continued. Liver-spleen scans were obtained on an urgent basis to confirm the diagnosis of splenic injury in patients who did not undergo surgery. No complications of treatment without surgery were recognized. The satisfactory outcome in these patients suggests that there is a place for treatment without surgery in some children with splenic injury.

The risk of overwhelming postsplenectomy infection (OPSI) prompted the evolution toward preservation of the injured spleen. Nonoperative management (NOM) of blunt injury to the spleen in adults has become the standard of care in hemodynamically stable patients. This modality of treatment began in the 1970’s in paediatric patients. It is highly successful with overall failures rates from 2% to 31% (average 10.8%) - with the majority of failures occurring in the first 24 hours. Current, NOM of splenic trauma includes splenic artery embolization. However, the criteria for NOM are controversial. In this study we present the current criteria, the evolution and failure rates of this type of management viewed through the general knowledge and, particularly, our experience. PMID:22574087

The study of skin and bone lesions may give information concerning type and manner of production, but in burnt material modification of tissues by the high temperatures may considerably change the morphological characteristics of the lesions. This study aims at pointing out the effects of burning head of pigs with several types of lesions (blunt trauma, sharp force, and gunshot lesions) on soft tissues and bones, both from a morphological and chemical point of view. Results show that the charring process does not completely destroy signs of lesions on bones, which can often be recovered by cleaning bone surface from charred soft-tissue residues. Furthermore, neutron activation analysis test proved that antimony may be detectable also on gunshot entry wounds at the final stages of charring process.

Patients with thoracic trauma constitute one third of all the trauma cases. Of traumatic patients, 20-25 % die because of thoracic trauma. Our aim was to compare our clinical experience and the results with the related literature. Four hundred thirty-three patients, who underwent surgical interventions due to thoracic trauma, were evaluated. The latest form of treatment applied were taken as the criteria for the quantitative detection of patients. Continuous variables were expressed as mean ± standard deviation, while categorical variables were explained as number and percentage. The significance of the analysis results was evaluated using Fisher's exact test. p values <0.05 were considered as significant. Penetrating injuries were found in 258 (59 %) of the patients, and blunt trauma was identified in 175 (41 %). Depending on the trauma, pneumothorax was discovered in 130 patients (30.02 %), hemothorax in 117 (27.02 %), hemopneumothorax in 61 (14.08 %), pulmonary contusion in 110 (45 %), pneumomediastinum in 14 (3.23 %), and pericardial tamponade in 1 patient (0.23 %). It was demonstrated that 385 of 433 patients examined in the study underwent tube thoracostomy, 41 were treated with thoracotomy, while 6 of them underwent video-assisted thoracoscopic surgery (VATS), and 1 underwent sternotomy. No correlation was observed between mortality, morbidity, and gender and type of trauma and location of trauma (p > 0.05). However, statistically significant correlation was found between mortaxlity, morbidity, and the presence of concomitant injuries, the duration between injury and admission being more than 1 h (p < 0.05). Urgent intervention, early diagnosis, and fast transport are vital for patients with thoracic injuries.

The aim of this study is to develop a reliable and efficient design tool that can be used in hypersonic flows. The flow analysis is based on the axisymmetric Euler/Navier-Stokes and finite-rate chemical reaction equations. The equations are coupled simultaneously and solved implicitly using Newton's method. The Jacobian matrix is evaluated analytically. A gradient-based numerical optimization is used. The adjoint method is utilized for sensitivity calculations. The objective of the design is to generate a hypersonic blunt geometry that produces the minimum drag with low aerodynamic heating. Bezier curves are used for geometry parameterization. The performances of the design optimization method are demonstrated for different hypersonic flow conditions.

The effect of hyperbaric oxygenation (HBO2) on survival during the early phase of severe blunt chest injury (BChI) has not been elucidated. Our aim was to investigate this effect on human victims of BChI. We monitored cardiac index (CI), stroke volume index (SVI), PaO2 and PaO2/FiO2 in 18 victims treated conventionally, and 8 victims treated under combined conventional and HBO2 treatment. Out of the 18 victims, 4 survived (Group A) and 14 died (Group B). Another 8 victims, in Group C, received HBO, and all survived. Human victims showed marked reductions in all cardiorespiratory values during the first 24 h. Group B persistently tended towards a decrease in SVI, PaO2/FiO2 and PaO2, eventually reaching fatal levels. The survivors developed a cardiorespiratory function characterized by a tendency towards recovery of all monitored parameters, more notable in Group C, which showed an earlier and more significant normalization vs. Group A (P<0.01). Our clinical data suggest that the earliest possible HBO2 treatment after severe blunt trauma can significantly enhance victims' survival.

ehind Armor Blunt Trauma (BABT) is a persistent concern for both the military and civil law enforcement. Although personal protective equipment (PPE), including soft and hard body armor, mitigates penetrating injuries from ballistic threats, the impact generates a backface deformation which creates a high-rate blunt impact to the body and potential internal injury (i.e., BABT). A critical need exists to understand the mechanics of the human response and subsequently evaluate the efficacy of current and proposed PPE in mitigating BABT injury risk. Current human surrogate test platforms lack anatomical fidelity or instrumentation for capturing the dynamic transfer of energy during the event. Therefore, we have developed and tested a Human Surrogate Torso Model (HSTM) composed of biosimulants representing soft tissues and skeleton of the human torso. A matrix of pressure transducers were embedded in the soft tissue and a custom displacement sensor was mounted to the skeletal structure to measure sternum displacement. A series of non-penetrating, high energy ballistic tests were performed with the HSTM. Results indicate that both sternum displacement and internal localized pressure are sensitive to impact energy and location. These data provide a spatial and temporal comparison to the current standard (static clay measurements) and a method for evaluating the applicability of thoracic injury metrics, including the Viscous Criterion, for BABT. The HSTM provides an advanced, biomechanically relevant test platform for determining the thoracic response to dynamic loading events due to non-penetrating ballistic impacts.

BACKGROUND: Modern civilization and the sharp rise in living standards have led to dramatic changes in trauma pattern in Saudi Arabia. This study aimed to describe the different patterns of injuries of patients attending the Emergency Department of Jazan General Hospital (JGH) in the southwest corner of Saudi Arabia. METHODS: A total number of 1 050 patients were enrolled in the study. A pre-organized data sheet was prepared for each patient attended the Emergency Department of JGH from February 2012 to January 2013. It contains data about socio-demographics, trauma data, clinical evaluation results, investigations as well as treatment strategies. RESULTS: The mean age of the patients was 25.3±16.8 years. Most (45.1%) of the patients were at age of 18–30 years. Males (64.3%) were affected by trauma more common than females. More than half (60.6%) of the patients were from urban areas. The commonest kind of injury was minor injury (60%), followed by blunt trauma (30.9%) and then penetrating trauma (9.1%). The mean time from the incident to arrival at hospital was 41.3±79.8 minutes. The majority (48.2%) of the patients were discharged after management of trivial trauma, whereas 2.3% were admitted to ICU, 7.7% transferred to inpatient wards, and 17.7% observed and subsequently discharged. The mortality rate of the patients was 2.6%. CONCLUSION: Trauma is a major health problem, especially in the young population in Saudi Arabia. Blunt trauma is more frequent than penetrating trauma, with road traffic accidents accounting for the majority. PMID:25802567

Fractures of the tibial plateau are relatively rare, representing around 1.2% of all fractures. The tibia, due to its subcutaneous location and poor muscle coverage, is exposed and suffers large numbers of traumas, not only fractures, but also crush injuries and severe bruising, among others, which at any given moment, could lead compartment syndrome in the patient. The case is reported of a 58-year-old patient who, following a tibial plateau fracture, presented compartment syndrome of the leg and was submitted to decompressive fasciotomy of the four right compartments. After osteosynthesis with internal fixation of the tibial plateau using an L-plate, the patient again developed compartment syndrome.

Background Craniomaxillofacial (CMF) fractures are typically treated with open reduction and internal fixation. Open reduction and internal fixation can be complicated by hardware exposure or infection. The literature often does not differentiate between these 2 entities; so for this study, we have considered all hardware exposures as hardware infections. Approximately 5% of adults with CMF trauma are thought to develop hardware infections. Management consists of either removing the hardware versus leaving it in situ. The optimal approach has not been investigated. Thus, a systematic review of the literature was undertaken and a resultant evidence-based approach to the treatment and management of CMF hardware infections was devised. Materials and Methods A comprehensive search of journal articles was performed in parallel using MEDLINE, Web of Science, and ScienceDirect electronic databases. Keywords and phrases used were maxillofacial injuries; facial bones; wounds and injuries; fracture fixation, internal; wound infection; and infection. Our search yielded 529 articles. To focus on CMF fractures with hardware infections, the full text of English-language articles was reviewed to identify articles focusing on the evaluation and management of infected hardware in CMF trauma. Each article’s reference list was manually reviewed and citation analysis performed to identify articles missed by the search strategy. There were 259 articles that met the full inclusion criteria and form the basis of this systematic review. The articles were rated based on the level of evidence. There were 81 grade II articles included in the meta-analysis. Result Our meta-analysis revealed that 7503 patients were treated with hardware for CMF fractures in the 81 grade II articles. Hardware infection occurred in 510 (6.8%) of these patients. Of those infections, hardware removal occurred in 264 (51.8%) patients; hardware was left in place in 166 (32.6%) patients; and in 80 (15.6%) cases

Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13%) following blunt injury and 20 (87%) after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury. PMID:23723618
Introduction Ureteral trauma is rare, accounting for less than 1% of all urologic traumas. However, a missed ureteral injury can result in significant morbidity and mortality. The purpose of this article is to review the literature since 1961 with the primary objective to present the largest medical literature review, to date, regarding ureteral trauma. Several anatomic and physiologic considerations are paramount regarding ureteral injuries management. Literature review Eighty-one articles pertaining to traumatic ureteral injuries were reviewed. Data from these studies were compiled and analyzed. The majority of the study population was young males. The proximal ureter was the most frequently injured portion. Associated injuries were present in 90.4% of patients. Admission urinalysis demonstrated hematuria in only 44.4% patients. Intravenous ureterogram (IVU) failed to diagnose ureteral injuries either upon admission or in the operating room in 42.8% of cases. Ureteroureterostomy, with or without indwelling stent, was the surgical procedure of choice for both trauma surgeons and urologists (59%). Complications occurred in 36.2% of cases. The mortality rate was 17%. Conclusion The mechanism for ureteral injuries in adults is more commonly penetrating than blunt. The upper third of the ureter is more often injured than the middle and lower thirds. Associated injuries are frequently present. CT scan and retrograde pyelography accurately identify ureteral injuries when performed together. Ureteroureterostomy, with or without indwelling stent, is the surgical procedure of choice of both trauma surgeons and urologists alike. Delay in diagnosis is correlated with a poor prognosis.

Background The overall incidence of fractures has been addressed in several studies, but there are few data on different types of fractures that require inpatient care, even though they account for considerable healthcare costs. We determined the incidence of limb and spine fractures that required hospitalization in people aged ≥ 16 years. Patients and methods We collected data on the diagnosis (ICD10 code), procedure code (NOMESCO), and 9 additional characteristics of patients admitted to the trauma ward of Central Finland Hospital between 2002 and 2008. Incidence rates were calculated for all fractures using data on the population at risk. Results and interpretation During the study period, 3,277 women and 2,708 men sustained 3,750 and 3,030 fractures, respectively. The incidence of all fractures was 4.9 per 103 person years (95% CI: 4.8–5.0). The corresponding numbers for women and men were 5.3 (5.1–5.4) and 4.5 (4.3–4.6). Fractures of the hip, ankle, wrist, spine, and proximal humerus comprised two-thirds of all fractures requiring hospitalization. The proportion of ankle fractures (17%) and wrist fractures (9%) was equal to that of hip fractures (27%). Four-fifths of the hospitalized fracture patients were operated. In individuals aged < 60 years, fractures requiring hospitalization were twice as common in men as in women. In individuals ≥ 60 years of age, the opposite was true. PMID:24694275

In this report, we describe 6 children with osteogenesis imperfecta with unusual stress femoral fractures. All children were on long-term cyclic pamidronate treatment. All fractures occurred without trauma or with minimal trauma and were located in the subtrochanteric or the diaphyseal regions of the femur over preexisting intramedullary rods. These fractures have very similar features to the reported minimal trauma atypical femoral fractures in adults on long-term bisphosphonate treatment. These fractures raise concerns about the role of prolonged remodeling suppression and microdamage accumulation and the risk of increased bone fragility.

Clavicular fractures commonly occur in adults and children. The usual mechanism of injury is a fall on the outstretched hand or direct trauma. The usual site of these fractures is the mid clavicle with lateral end and medial end clavicular fractures being less common, respectively. Segmental clavicular fractures have been reported in the literature; they usually occur at the medial and lateral ends and tend to occur in adults. Bipolar clavicular injuries involving medial and lateral ends have also been reported rarely but all in adults. We report a very rare case of segmental clavicular fracture involving the mid clavicle and lateral end in an adolescent caused by direct trauma. The management of segmental clavicle fractures has not been clearly outlined although operative intervention is indicated. We report the successful management of segmental fracture clavicle in an adolescent and discuss the relevant literature. PMID:23476850

The most prevalent fractures managed by trauma surgeons are those involving the distal radius. The injury occurs in two peaks of prevalence: the first peak around the age of 10 years and the second peak around the age of 60 years. Distal radius fracture management requires sensitive diagnostics and classification. The objectives of treatment are the reconstruction of a pain-free unlimited durable functioning of the wrist and avoidance of typical fracture complications. Non-operative conservative management is generally employed for stable non-displaced fractures of the distal radius with the expectation of a good functional outcome. Unstable comminuted fractures with intra-articular and extra-articular fragment zones are initially set in a closed operation and finally by osteosynthesis. An armament of surgical implants is available for instable fractures requiring fixation. Palmar locked plate osteosynthesis has been established in recent years as the gold standard for operative management of distal radius fractures. Complex Working Group on Osteosynthesis (AO) classification type 3 fractures require extensive preoperative diagnostics to identify and treat typical associated injuries around the wrist.

Hemothorax is common in elderly patients following blunt chest trauma. Traditionally, tube thoracostomy is the first choice for managing this complication. The goal of this study was to determine the benefits of this approach in elderly patients with and without an initial tube thoracostomy. Seventy-eight patients aged >65 years with blunt chest trauma and stable vital signs were included. All of them had more than 300 mL of hemothorax, indicating that a tube thoracostomy was necessary. The basic demographic data and clinical outcomes of patients with hemothorax who underwent direct video-assisted thoracoscopic surgery without a tube thoracostomy were compared with those who received an initial tube thoracostomy. Patients who did not receive a thoracostomy had lower posttrauma infection rates (28.6% versus 56.3%, P = 0.061) and a significantly shorter length of stay in the intensive care unit (3.13 versus 8.27, P = 0.029) and in the hospital (15.93 versus 23.17, P = 0.01) compared with those who received a thoracostomy. The clinical outcomes in the patients who received direct VATS were more favorable compared with those of the patients who did not receive direct VATS. PMID:27190987

The provision of trauma care is a financial burden, continually associated with low reimbursement, and shifts the economic burden to major trauma centers and providers. Meanwhile, the volume of craniomaxillofacial (CMF) trauma and the number of surgically managed facial fractures are unchanged. Past financial analyses of cost and reimbursement for facial trauma are limited to mandibular and midface injuries, consistently revealing low reimbursement. The incurred financial burden also coincides with the changing landscape of health insurance. The goal of this study is to determine the opportunity cost of operative management of facial trauma at our institution. From our CMF database of greater than 3,000 facial fractures, the physician charges, collections, and relative value units (RVUs) for CMF trauma per year from 2007 to 2013 were compared with a general plastic surgery and otolaryngology population undergoing operative management during this same period. Collection rates were analyzed to assess if a significant difference exists between reimbursement for CMF and non-CMF cases. Results revealed a significant difference between the professional collection rate for operative CMF trauma and that for other operative procedures (17.25 vs. 29.61%, respectively; p < 0.0001). The average number of RVUs billed per provider for CMF trauma declines significantly, from greater than 700 RVUs to 300 over the study period, despite a stable volume. Surgical management of CMF trauma generates an unfavorable financial environment. The large opportunity cost associated with offering this service is a potential threat to the sustainability of providing care for this population.

Genitourinary system injuries generally occur due to blunt and penetrating trauma. Approximately 10% of all injuries encountered in the emergency department are related to the genitourinary system. Male genital trauma is a urological emergency because of the high risk of infection and the priority of protecting the sexual, endocrine, and reproductive functions. Blunt injuries to the penis are more often seen due to the mobility and localization of the penis than due to penetrating injuries caused by firearms or cutting instruments. We aimed to present and discuss a case involving shrapnel that became lodged in the penis of a child in a war zone. After 2 weeks of medical treatment, the patient underwent surgery. Surgery includes primary repair to the penis and urethra. PMID:28149826

Rationale: Acute lung injury is a common complication after severe trauma, which predisposes patients to multiple organ failure. This syndrome largely accounts for the late mortality that arises and despite many theories, the pathological mechanism is not fully understood. Discovery of histone-induced toxicity in mice presents a new dimension for elucidating the underlying pathophysiology. Objectives: To investigate the pathological roles of circulating histones in trauma-induced lung injury. Methods: Circulating histone levels in patients with severe trauma were determined and correlated with respiratory failure and Sequential Organ Failure Assessment (SOFA) scores. Their cause–effect relationship was studied using cells and mouse models. Measurements and Main Results: In a cohort of 52 patients with severe nonthoracic blunt trauma, circulating histones surged immediately after trauma to levels that were toxic to cultured endothelial cells. The high levels were significantly associated with the incidence of acute lung injury and SOFA scores, as well as markers of endothelial damage and coagulation activation. In in vitro systems, histones damaged endothelial cells, stimulated cytokine release, and induced neutrophil extracellular trap formation and myeloperoxidase release. Cellular toxicity resulted from their direct membrane interaction and resultant calcium influx. In mouse models, cytokines and markers for endothelial damage and coagulation activation significantly increased immediately after trauma or histone infusion. Pathological examinations showed that lungs were the predominantly affected organ with edema, hemorrhage, microvascular thrombosis, and neutrophil congestion. An anti-histone antibody could reduce these changes and protect mice from histone-induced lethality. Conclusions: This study elucidates a new mechanism for acute lung injury after severe trauma and proposes that circulating histones are viable therapeutic targets for improving survival

Purpose: To study the epidemiology and clinical profile of victims of ocular trauma in an urban slum population. Materials and Methods: This cross-sectional study, conducted on 500 families each in three randomly selected urban slums in Delhi, collected demographic data for all members of these families, and clinical data for all those who suffered ocular trauma at any time, that required medical attention. Data was managed on SPSS 11.0. Results: Of 6704 participants interviewed, 163 episodes of ocular trauma were reported by 158 participants (prevalence = 2.4%, confidence interval = 2.0 to 2.7) Mean age at trauma was 24.2 years. The association between the age of participants and the history of ocular trauma was significant (P < 0.001), when adjusted for sex, education and occupation. Males were significantly more affected. Blunt trauma was the commonest mode of injury (41.7%). Blindness resulted in 11.4% of injured eyes ( P = 0.028). Of 6704 participants, 1567 (23.4%) were illiterate, and no association was seen between education status and trauma, when adjusted for sex and age at injury. A significant association was noted between ocular trauma and workplace (Chi-square = 43.80, P < 0.001), and between blindness and place (Chi-square = 9.98, P = 0.041) and source (Chi-square = 10.88, P = 0.028) of ocular trauma. No association was found between visual outcome and the time interval between trauma and first consultation (Chi-square = 0.50, P = 0.78), between receiving treatment and the best corrected visual acuity (Chi-square = 0.81, P = 0.81), and between the person consulted and blinding ocular trauma (Chi-square = 1.88, P = 0.170). Conclusion: A significant burden of ocular trauma in the community requires that its prevention and early management be a public health priority. PMID:18579991

Forefoot traumas, particularly involving the metatarsals, are commonly occurring injuries. There have been several advances in management of these injuries. These advances include updates in operative technique, internal fixation options, plating constructs, and external fixation. In addition, the advances of soft tissue management have improved outcomes. This article outlines these injuries and provides an update on techniques, principles, and understanding of managing forefoot trauma.

Paleopathological assessment of the late Middle Pleistocene archaic human cranium from Maba, South China, has documented a right frontal squamous exocranially concave and ridged lesion with endocranial protrusion. Differential diagnosis indicates that it resulted from localized blunt force trauma, due to an accident or, more probably, interhuman aggression. As such it joins a small sample of pre-last glacial maximum Pleistocene human remains with probable evidence of humanly induced trauma. Its remodeled condition also indicates survival of a serious pathological condition, a circumstance that is increasingly documented for archaic and modern Homo through the Pleistocene. PMID:22106311

Partial optic nerve avulsion (ONA) secondary to finger gouging is an uncommon but devastating injury. A 21-year-old man who had an acute vision loss after accidentally getting poked by himself in his right eye when he fell down during jogging is reported. The patient was diagnosed with partial ONA. Magnetic resonance imaging revealed intact optic nerve. Optical coherence tomography (OCT) revealed deep cavity at the inferior-temporal half of the optic disc. Retinal nerve fiber layer thickness was also thin at the inferior quadrant with circumpapillary OCT scan. Visual field test and electrophysiological tests showed functional abnormality compatible with optic nerve lesion. Diagnostic tools for anatomical and functional evaluation may reveal the course of this injury. PMID:20952839

La rotura traqueal tras una contusión es rara, aunque potencialmente mortal. En general, se recomienda el tratamiento quirúrgico para la rotura traqueal, aunque también se ha informado recientemente el abordaje conservador en los pacientes con signos vitales y parámetros respiratorios estables. El objetivo de este estudio es informar sobre un caso de rotura traqueal tras una contusión en el cuello producto de un accidente de bicicleta que se trató de manera conservadora.
Introduction Crush asphyxia is different from positional asphyxia, as respiratory compromise in the latter is caused by splinting of the chest and/or diaphragm, thus preventing normal chest expansion. There are only a few cases or small case series of crush asphyxia in the literature, reporting usually poor outcomes. Case presentation We present the case of a 44-year-old Caucasian man who developed traumatic asphyxia with severe thoracic injury and mild brain edema after being crushed under heavy auto vehicle mechanical parts. He remained unconscious for an unknown time. The treatment included oropharyngeal intubation and mechanical ventilation, bilateral chest tube thoracostomies, treatment of brain edema and other supportive measures. Our patient’s outcome was good. Traumatic asphyxia is generally under-reported and most authors apply supportive measures, while the final outcome seems to be dependent on the length of time of the chest compression and on the associated injuries. Conclusion Treatment for traumatic asphyxia is mainly supportive with special attention to the re-establishment of adequate oxygenation and perfusion; treatment of the concomitant injuries might also affect the final outcome.

We present a case of a growing skull fracture in adult male, with an interval of 43 years after initial trauma. This finding is extremely rare, especially because growing skull fractures are mostly seen as an uncommon complication of pediatric head trauma with calvarial fracture. In our patient, this finding was incidental, existed for many years, and had no clinical consequences. Therefore, we advised a conservative treatment for our patient.

Trauma is one of the leading causes of death before the age of 40 years and approximately 5% of patients with trauma who require hospital admission have pelvic fractures. This article updates the emergency department classification of pelvic fractures first described in 2000. This information is of practical value to emergency physicians in identifying the potential vascular, genitourinary, gastrointestinal, orthopedic, and neurologic complications and further assists them in the initial evaluation and treatment of patients with pelvic fractures.
Contact sports have long been a part of human existence. The two earliest recorded organized contact games, both of which still exist, include Royal Shrovetide Football played since the 12th century in England and Caid played since 1308 AD in Ireland. Rugby is the premier contact sport played throughout the world with the very popular derivative American football being the premier contact sport of the North American continent. American football in the USA has on average 1,205,037 players at the high school and collegiate level per year while rugby in the USA boasts a playing enrollment of 457,983 at all levels. Recent media have highlighted injury in the context of competitive contact sports including their long-term sequelae such as chronic traumatic encephalopathy (CTE) that had previously been underappreciated. Blunt cerebrovascular injury (BCVI) has become a recognized injury pattern for trauma; however, a paucity of data regarding this injury can be found in the sports trauma literature. We present a case of an international level scrum-half playing Rugby Union at club level for a local non-professional team, in which a player sustained a fatal BCVI followed by a discussion of the literature surrounding sport related BCVI.

Bongs and blunts constitute significant elements of marijuana consumption in the United States, especially among youth. The author draws upon ethnographic methods to provide rich descriptions of these practices amongst a network of suburban marijuana users. The author first provides a description of bong use in a suburban home prior to detailing the same youth network engaging in the process of rolling and smoking a blunt in a public environment. Ultimately, the author examines and contrasts these two features of American marijuana consumption.

The aims of this study were to assess the incidence of reverse Segond fracture, to examine the associated ligamentous injuries, and to examine how often reverse Segond fracture coexists with a knee dislocation. At a level 1 trauma center, an 11-year period of emergency department multidetector-row computed tomography (MDCT) examinations for knee trauma was evaluated for reverse Segond and Segond fractures. Surgical findings served as the reference standard for intra-articular injuries. The hospital discharge register was searched for the diagnosis of knee dislocation from August 2000 through the end of August 2011. A total of 1,553 knee MDCT examinations were evaluated. Ten patients with a reverse Segond fracture were found, comprising 0.64 % of emergency room acute knee trauma MDCT examinations. Seven patients who had a reverse Segond fracture were operated: Three had an avulsion fracture of the anterior cruciate ligament, one had an avulsion fracture of posterior cruciate ligament, two had a lateral meniscal tear, and two had a medial collateral ligament tear. The ratio of reverse Segond fractures to Segond fractures was 1:4. None of the 71 knee dislocation patients had a reverse Segond fracture. Reverse Segond fracture is a rare finding even in a level 1 trauma center. Cruciate ligament injuries appear to be associated with avulsion fracture, but every patient does not have PCL injury, as previously reported. Our results do not support the association of knee dislocation with reverse Segond fracture.
In much of contemporary culture, "trauma" signifies not so much terrible experience as a particular context for understanding and responding to a terrible experience. In therapy, in the media, and in international interventions, the traumatized are seen not simply as people who suffer and so are deserving of concern and aid; they are seen also as people who suffer for us, who are given special dispensation. They are treated with awe if they tell a certain kind of trauma story, and are ignored or vilified if they tell another. Trauma has become not simply a story of pain and its treatment, but a host of sub-stories involving the commodification of altruism, the justification of violence and revenge, the entry point into "true experience," and the place where voyeurism and witnessing intersect. Trauma is today the stuff not only of suffering but of fantasy. Historically, trauma theory and treatment have shown a tension, exemplified in the writings of Freud and Janet, between those who view trauma as formative and those who view it as exceptional. The latter view, that trauma confers exceptional status deserving of special privilege, has gained ground in recent years and has helped to shape the way charitable dollars are distributed, how the traumatized are presented in the media, how governments justify and carry out international responses to trauma, and how therapists attend to their traumatized patients. This response to trauma reflects an underlying, unarticulated belief system derived from narcissism; indeed, trauma has increasingly become the venue, in society and in treatment, where narcissism is permitted to prevail.

Background Rheumatoid arthritis (RA) is known to have many predisposing factors. Objective We studied individuals whose RA was initiated by physical injuries. Patients and methods Sixty patients (43 females), previously well, developed RA following trauma. No other known environmental or familial influences were present. Fourteen sustained a fracture; of the 46 who did not, 36 sustained multiple injuries that in part involved the axial skeleton. Subsequent unremitting daily pain, stiffness, limited motion, pain on motion, and/or swelling in the injured areas were mandatory for inclusion. Results Nine months after injuries (span: 2 weeks–36 months), more obvious signs of inflammation (IM) appeared in multiple other joints that were previously not affected by the original trauma. In those with laboratory tests done prior to the spread of IM (30/60), 22 (73%) were normal until an average 8 months after the spread of IM. Of the entire cohort of 60, only 23% had a positive rheumatoid factor, but 43% had a positive antinuclear antibody. Conclusion It seems apparent that any severe trauma to a joint may precipitate an ongoing localized chronic inflammatory disorder for an indefinite period of time, which may then lead to the spread of IM to multiple other joints. The initiation of RA following trauma warrants consideration as a legitimate entity. PMID:27843373

Fractures of the atlas account for 1-2% of all vertebral fractures. We divide atlas fractures into 5 groups: isolated fractures of the anterior arch of the atlas, isolated fractures of the posterior arch, combined fractures of the anterior and posterior arch (so-called Jefferson fractures), isolated fractures of the lateral mass and fractures of the transverse process. Isolated fractures of the anterior or posterior arch are benign and are treated conservatively with a soft collar until the neck pain has disappeared. Jefferson fractures are divided into stable and unstable fracture depending on the integrity of the transverse ligament. Stable Jefferson fractures are treated conservatively with good outcome while unstable Jefferson fractures are probably best treated operatively with a posterior atlanto-axial or occipito-axial stabilization and fusion. The authors preferred treatment modality is the immediate open reduction of the dislocated lateral masses combined with a stabilization in the reduced position using a transarticular screw fixation C1/C2 according to Magerl. This has the advantage of saving the atlanto-occipital joints and offering an immediate stability which makes immobilization in an halo or Minerva cast superfluous. In late instabilities C1/2 with incongruency of the lateral masses occurring after primary conservative treatment, an occipito-cervical fusion is indicated. Isolated fractures of the lateral masses are very rare and may, if the lateral mass is totally destroyed, be a reason for an occipito-cervical fusion. Fractures of the transverse processes may be the cause for a thrombosis of the vertebral artery. No treatment is necessary for the fracture itself.

The parachutist injured in a dramatic accident often describes the injury in an incomplete and biased way and evaluation of materials based solely upon subjective information of this kind can be misleading and of no value for recommendations. As the relation between the mechanical factors of the injury and the lesion in ankle fractures is well documented, an investigation of clinical, radiological and operative findings in 46 parachutists with ankle fractures was conducted. Classification was possible in 44 of 46 fractures. The description of the cause of the trauma in 21 supination-eversion fractures and in 13 pronation-eversion fractures was most frequently faulty landing position or obstacles. The cause of seven supination fractures was oscillation of the parachutist whilst descending with sudden impact against the lateral aspect of the foot. For prophylaxis we recommend improvement of landing and steering techniques and the support of semi-calf boots. PMID:2730996

We report a previously healthy 4-month-old who presented to the hospital with leg pain and swelling and no history of trauma. Radiographs demonstrated a comminuted left femur fracture. Given the concern for child abuse, skeletal survey was performed and revealed four vertebral compression deformities. Although abuse was suspected, the possibility of a lytic lesion associated with the femur fracture and multiple spinal abnormalities raised the possibility of an underlying process such as Langerhans cell histiocytosis. Subsequently 18F-NaF positron emission tomographic (PET) scintigraphy revealed increased tracer activity in the ischium, and MRI confirmed an ischial apophyseal fracture. Pelvic fractures, particularly ischial fractures, are extremely rare in the setting of child abuse. This case report describes the multimodality imaging findings of an ischial fracture in an abused infant.

A case of a C1 posterior arch fracture following a fall is presented. The need to perform a thorough history and examination, regardless of previous examination findings, is emphasized. This is especially true when there is a history of recent trauma. A brief discussion of the characteristics and management of C1 fractures follows. ImagesFigure 1Figure 2Figure 3
Malocclusion is a serious complication of open reduction surgery for facial fractures. It is often caused by the lack of adequate consideration for the occlusal relationship before the trauma and intermaxillary fixation during the operation. This is a case report of postoperative malocclusion that occurred in a patient with a midfacial complex fracture. PMID:28280712

The objective of the study is to better understand how blunt projectile ballistic parameters and material properties influence the events leading to injuries. The present work focuses on lateral thoracic impacts and follows an experimental approach. The projectiles are made with a soft foam nose assembled with a rigid rear plastic part. The dynamic properties of the foams were first determined using the Split Hopkinson Pressure Bar (SHPB) system. The impact forces on a rigid wall were then measured to provide reference load data. Lastly, shots were made on isolated thoraxes of porcine cadavers to investigate the response in the vicinity of the impact (wall displacements, rib accelerations and strains, rib fractures). Results show that the severity of the response appears to be mainly correlated with the impulse and with the pre-impact momentum.
