Improving reduction of the pelvic ring improves long-term functional outcomes for patients. It has been demonstrated that posterior internal fixation is necessary to adequately control fractures to the posterior ring and there is evidence that supplementing this with fixation of the anterior ring improves stability. It is accepted that internal fixation provides greater stability than external fixation of the anterior ring but long-term differences in radiographic and functional outcomes have not yet been quantified. A search of electronic databases, reference lists and review articles from 1989 to 2015 yielded 18 studies (n = 884) that met our inclusion criteria. We included studies that discussed pelvic ring injuries in adults, reported functional or radiological outcomes or complications by anterior ring intervention and exceeded 14 patients. We excluded biomechanical and cadaver studies. Internal fixation of the anterior pelvic ring had better functional and radiographic outcomes. Residual displacement of >10 mm was less common with internal fixation (ER 0.12, 95 % CI 0.06-0.24) than external fixation (ER 0.31, 95 % CI 0.11-0.62). Unsatisfactory outcomes also occurred at a lower rate (ER 0.09, 95 % CI 0.03-0.22) compared to external fixation (ER 0.32, 95 % CI 0.18-0.50). Losses of reduction (ER 0.02, 95 % CI 0.01-0.04 versus ER 0.07, 95 % CI 0.02-0.21), malunions (ER 0.03, 95 % CI 0.01-0.08 versus ER 0.07, 95 % CI 0.02-0.21) and delayed/non-unions (ER 0.02, 95 % CI 0.01-0.05 versus ER 0.04, 95 % CI 0.02-0.07). Internal fixation of the anterior pelvic ring as supplementary fixation for unstable injuries to the pelvic ring appears to result in better radiographic and functional outcomes as well as fewer complications. However, data that separated outcomes and complications in relation to interventions of the anterior pelvic ring were limited. More studies looking specifically at outcomes in relation to the type of anterior ring intervention are

Treating pelvic fractures remains a challenging task for orthopaedic surgeons. We aimed to evaluate the feasibility, accuracy, and effectiveness of three-dimensional (3D) printing technology and computer-assisted virtual surgery for pre-operative planning in anterior ring fractures of the pelvis. We hypothesized that using 3D printing models would reduce operation time and significantly improve the surgical outcomes of pelvic fracture repair. We retrospectively reviewed the records of 30 patients with pelvic fractures treated by anterior pelvic fixation with locking plates (14 patients, conventional locking plate fixation; 16 patients, pre-operative virtual simulation with 3D, printing-assisted, pre-contoured, locking plate fixation). We compared operative time, instrumentation time, blood loss, and post-surgical residual displacements, as evaluated on X-ray films, among groups. Statistical analyses evaluated significant differences between the groups for each of these variables. The patients treated with the virtual simulation and 3D printing-assisted technique had significantly shorter internal fixation times, shorter surgery duration, and less blood loss (- 57 minutes, - 70 minutes, and - 274 ml, respectively; P < 0.05) than patients in the conventional surgery group. However, the post-operative radiological result was similar between groups (P > 0.05). The complication rate was less in the 3D printing group (1/16 patients) than in the conventional surgery group (3/14 patients). The 3D simulation and printing technique is an effective and reliable method for treating anterior pelvic ring fractures. With precise pre-operative planning and accurate execution of the procedures, this time-saving approach can provide a more personalized treatment plan, allowing for a safer orthopaedic surgery.

This study was performed to evaluate functional and radiological results of pelvic ring fractures treatment by open reduction and internal fixation. Thirty eight patients with unstable pelvic fractures, treated from 2002 to 2008 were retrospectively reviewed. The mean patients' age was 37 years (range 20 to 67). Twenty six patients were men (4 patients with type B and 22 patients with type C fracture) and 12 women (7 patients with type B and 5 patients with type C fracture). The commonest cause was a road traffic accident (N=37, about 97%). Internal fixation was done by plaque with ilioinguinal and Kocher-Langenbeek approaches for anterior, posterior pelvic wall and acetabulum fracture respectively. Quality of reduction was graded according to Majeed score system. There were 11 type-C and 27 type-B pelvic fractures according to Tile's classification. Thirty six patients sustained additional injuries. The commonest additional injury was lower extremity fracture. The mean follow-up was 45.6 months (range 16 to 84 months).The functional outcome was excellent in 66%, good in 15%, fair in 11% and poor in 7% of the patients with type B pelvic fractures and functional outcome was excellent in 46%, good in 27%, fair in 27% and poor in 0% of the patients with type C pelvic fractures. There were four postoperative infections. No sexual functional problem was reported. Neurologic problem like Lateral cutaneous nerve of thigh injury recovered completely in 2 patients and partially in 2 patients. There was no significant relation between functional outcome and the site of fracture (P greater than 0.005). Unstable pelvic ring fracture injuries should be managed surgically by rigid stabilization. It must be carried out as soon as the general condition of the patient permits, and even up to two weeks.

To explore the effectiveness of Colorado 2 system in the stability reconstruction of sacroiliac joint fracture and dislocation in Tile C pelvic fracture. Between February 2009 and January 2011, 8 cases of Tile C pelvic fracture were treated with Colorado 2 system. There were 3 males and 5 females with an average age of 34.4 years (range, 22-52 years). Fractures were caused by traffic accident in 3 cases, by falling from height in 3 cases, and by crash of heavy object in 2 cases. According to Tile classification, 5 cases were classified as C1-2, 2 cases as C1-3, and 1 case as C2. The time between injury and operation was 5-10 days (mean, 7 days). After skeletal traction reduction, Colorado 2 system was used to fix sacroiliac joint, and reconstruction plate or external fixation was selectively adopted. The postoperative X-ray films showed that the reduction of vertical and rotatory dislocation was satisfactory, posterior pelvic ring achieved effective stability. All the incisions healed by first intention, and no blood vessel or nerve injury occurred. Eight patients were followed up 6-24 months (mean, 12 months). No loosening or breakage of internal fixation was observed and no re-dislocation of sacroiliac joint occurred. The bone healing time was 6-12 months (mean, 9 months). According to Majeed's functional criterion, the results were excellent in 5 cases, good in 2 cases, and fair in 1 case at last follow-up. Colorado 2 system could provide immediate stability of pelvic posterior ring and good maintenance of reduction effect, which is an effective method in the therapy of sacroiliac joint fracture and dislocation in Tile C pelvic fracture.

To determine the effectiveness of 'binder-off' plain pelvic radiographs in the assessment of pelvic ring injuries. All patients requiring operative intervention at our tertiary referral pelvic unit/major trauma centre for high-energy pelvic injuries between April 2012 and December 2014 were retrospectively identified. Pre-operative pelvic imaging with and without pelvic binder was reviewed with respect to fracture pattern and pelvic stability. The frequency with which the imaging without pelvic binder changed the opinion of the pelvic stability and need for operative intervention, when compared with the computed tomography (CT) scans and anteroposterior (AP) radiographs with the binder on, was assessed. Seventy-three percent (71 of 97) of patients had initial imaging with a pelvic binder in situ. Of these, 76% (54 of 71) went on to have 'binder-off' imaging. Seven percent (4 of 54) of patients had unexpected unstable pelvic ring injuries identified on 'binder-off' imaging that were not identified on CT imaging in binder. Trauma CT imaging of the pelvis with a pelvic binder in place is inadequate at excluding unstable pelvic ring injuries, and, based on the original findings in this paper, we recommend additional plain film 'binder-off' radiographs, when there is any clinical concern.

The aim of this study is to determine the incidence and location of Morel-Lavallee lesions (MLLs) on pelvic CTs performed in evaluation of pelvic fractures and determine if correlation exists between MLLs and mechanism of injury or pelvic ring injury pattern. A retrospective review was performed of pelvic CTs on 1493 consecutive patients presenting with pelvic fractures at our level 1 trauma center. MLLs occurred in 182 of 1493 patients presenting with pelvic fractures. Statistical significance in MLL incidence was found across mechanism of injuries with MLLs being seen most frequently in MCC/ATV accidents and crush injuries. A little over half of MLLs occurred over the lateral thigh with almost all other MLLs occurring over the posterior (flank or lumbar) region. MLLs were much more common in vertical shear and spinopelvic dissociation pelvic ring fracture patterns compared to lateral compression and AP compression patterns. In lateral compression injuries, MLLs most commonly occurred over the thigh. In all other pelvic ring injury patterns, MLLs were predominately posterior. MLL's are not as rare as previously believed. The lateral thigh and lumbar/flank regions should be closely inspected on pelvic trauma patients to identify MLLs, particularly in patients with a spinopelvic dissociation injury pattern.

Pelvic fracture in multiple trauma: are we still up-to-date with massive fluid resuscitation?

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. Copyright © 2014 Elsevier Ltd. All rights reserved.

Pelvic ring injuries: Surgical management and long-term outcomes

PubMed Central

Halawi, Mohamad J.

2016-01-01

Pelvic ring injuries present a therapeutic challenge to the orthopedic surgeon. Management is based on the patient's physiological status, fracture classification, and associated injuries. Surgical stabilization is indicated in unstable injury patterns and those that fail nonsurgical management. The optimal timing for definitive fixation is not clearly defined, but early stabilization is recommended. Surgical techniques include external fixation, open reduction and internal fixation, and minimally invasive percutaneous osteosynthesis. Special considerations are required for concomitant acetabular fractures, sacral fractures, and those occurring in skeletally immature patients. Long-term outcomes are limited by lack of pelvis-specific outcome measures and burden of associated injuries. PMID:26908968

The prehospital management of pelvic fractures

Pelvic fractures are one of the potentially life‐threatening injuries that should be identified during the primary survey in patients sustaining major trauma. Early suspicion, identification and management of a pelvic fracture at the prehospital stage is essential to reduce the risk of death as a result of hypovolaemia and to allow appropriate triage of the patient. The assessment and management of pelvic fractures in the prehospital environment is reviewed here. It is advocated that the pelvis should not be examined by palpation or springing, and that the patient should not be log rolled. Pelvic immobilisation should be used routinely if there is any suspicion of pelvic fracture based on the mechanism of injury, symptoms and clinical findings. PMID:17251627

Unstable pelvic fractures can be life-threatening due to catastrophic haemorrhage. Non-invasive methods of reducing and stabilising these injuries include pelvic binder application and also lower limb bandaging over a knee-flexion bolster. Both of these methods help close the pelvic ring and should tamponade bleeding. This study aimed to quantify the intra-pelvic pressure changes that occurred with 3 different manoeuvres: lower limb bandaging over a bolster; a Trauma Pelvic Orthotic Device (T-POD) pelvic binder, and a combination of both. Following a pilot study with 2 soft embalmed cadavers, a formal study with 6 unembalmed cadavers was performed. For each specimen an unstable pelvic injury was created (OA/OTA 61-C1) by dividing the pelvic ring anteriorly and posteriorly. A 3-4cm manometric water-filled balloon was placed in the retropubic space and connected to a 50ml syringe and water manometer via a 3-way tap. A baseline pressure of 8cmH 2 O (equating to the average central venous pressure) was used for each cadaver. Steady intra-pelvic pressures (more reliably reflecting the pressures achieved following an intervention) were used in the subsequent statistical analysis, using R statistical language and Rstudio. Paired t-test or Wilcoxon's rank sum test were used (depending on the normality of the dataset) to determine the impact of each intervention on the intra-pelvic pressure. The mean steady intra-pelvic pressures were significantly greater than the baseline pressure for each intervention. The binder and limb bandaging over a bolster alone increased the mean steady pelvic pressures significantly to 24 (SE=5) (p<0.036) and 15.5 (SE=2) (p<0.02)cmH 2 O respectively. Combining these interventions further increased the mean steady pressure to 31 (SE=7)cmH 2 O. However, this was not significantly greater than pressures for each of the individual interventions. Both lower limb bandaging over a bolster and pelvic binder application significantly increased intra-pelvic

Open reduction and internal fixation of pelvic fractures could restore the stability of the pelvic ring, but there were several problems. Minimally invasive closed reduction cannulated screw treatment of pelvic fractures has lots advantages. However, how to insert the cannulated screw safely and effectively to achieve a reliable fixation were still hard for orthopedist. Our aim was to explore the significance of 3D printing technology as a new method for minimally invasive cannulated screw treatment of unstable pelvic fracture. One hundred thirty-seven patients with unstable pelvic fractures from 2014 to 2016 were retrospectively analyzed. Based on the usage of 3D printing technology for preoperative simulation surgery, they were assigned to 3D printing group (n = 65) and control group (n = 72), respectively. These two groups were assessed in terms of operative time, intraoperative fluoroscopy, postoperative reduction effect, fracture healing time, and follow-up function. The effect of 3D printing technology was evaluated through minimally invasive cannulated screw treatment. There was no significant difference in these two groups with respect to general conditions, such as age, gender, fracture type, time from injury to operation, injury cause, and combined injury. Length of surgery and average number of fluoroscopies were statistically different for 3D printing group and the control group (p < 0.01), i.e., 58.6 vs. 72.3 min and 29.3 vs. 37 min, respectively. Using the Matta radiological scoring systems, the reduction was scored excellent in 21/65 cases (32.3%) and good in 30/65 cases (46.2%) for the 3D printing group, versus 22/72 cases (30.6%) scored as excellent and 36/72 cases (50%) as good for the control group. On the other hand, using the Majeed functional scoring criteria, there were 27/65 (41.5%) excellent and 26/65 (40%) good cases for the 3D printing group in comparison to 30/72 (41.7%) and 28/72 (38.9%) cases for the control group

Radiology-based classifications of pelvic ring injuries and their relevance for the prognosis of morbidity and mortality are disputed in the literature. The purpose of this study was to evaluate potential differences between the pelvic ring injury classification systems by Tile and by Young and Burgess with regard to their predictive value on mortality, transfusion/infusion requirement and concomitant injuries. Two-hundred-and-eighty-five consecutive patients with pelvic ring fractures were analyzed for mortality within 30 days after admission, number of blood units and total volume of fluid infused during the first 24h after trauma, the Abbreviated Injury Severity (AIS) scores for head, chest, spine, abdomen and extremities as a function of the Tile and the Young-Burgess classifications. There was no significant relationship between occurrence of death and fracture pattern but a significant relationship between fracture pattern and need for blood units/total fluid volume for Tile (p<.001/p<.001) and Young-Burgess (p<.001/p<.001). In both classifications, open book fractures were associated with more fluid requirement and more severe injuries of the abdomen, spine and extremities (p<.05). When divided into the larger subgroups "partially stable" and "unstable", unstable fractures were associated with a higher mortality rate in the Young-Burgess system (p=.036). In both classifications, patients with unstable fractures required significantly more blood transfusions (p<.001) and total fluid infusion (p<.001) and higher AIS scores. In this first direct comparison of both classifications, we found no clinical relevant differences with regard to their predictive value on mortality, transfusion/infusion requirement and concomitant injuries.

Open pelvic disruptions represent high-energy injuries. The prompt identification and management of these injuries decreases their associated morbidity and mortality. Computed tomography (CT) scans are routinely obtained in the initial evaluation of patients with pelvic injuries. The purpose of this study is to identify the incidence and source of air densities noted on computed tomography (CT) scans of the abdominal and pelvic region in patients with pelvic fractures and evaluate the use of initial CT imaging as an adjunctive diagnostic tool to identify open injuries. A retrospective review of a prospectively collected database was performed at a single institution. Seven hundred and twenty-two consecutive patients with a pelvic disruption over a two-year period were included. Review of initial injury CT scans was performed using bone and lung viewing algorithms to identify the presence of extra-luminal air. The primary outcome was the presence, location and source of air identified on pre-operative CT scans. Secondary measurements were identification of air by plain radiograph and correlation between identified air densities on CT and clinically diagnosed open pelvic fractures. Ninety-eight patients were identified as having extra-luminal air densities on CT scans. Eighty-one patients were included in the final analysis following application of inclusion and exclusion criteria. Air was noted by the radiologist in forty-five (55.6%) instances. Six patients (7.4%) were clinically diagnosed with an open pelvic ring disruption; in two patients (2.4%) this diagnosis was delayed. In all patients, the CT was able to track air from its origin. In patients with pelvic disruptions, the injury CT should also be evaluated for the presence and source of extra-luminal air. In some patients, this finding may represent an open pelvic ring disruption. A complete physical exam and CT evaluation should be used to decrease the missed or delayed diagnosis of an open pelvic ring

Complex pelvic ring fracture associated with floating knee is comparatively rare which usually results from high-energy trauma including vehicle-related accidence, falls from height, and earthquake-related injury. To our knowledge, few literatures have documented such injuries in the individual patient. Management of both injuries present challenges for surgical management and postoperative care. The purpose of this study is to prove the feasibility and benefits of damage control orthopedics (DCO). Our case involved a 45-year-old lady who was hit by a dilapidated building. The patient was anxious, pale and hemodynamically stable at the initial examination. The pelvis was unstable and there were obvious deformities in the left lower extremities. Significant degloved injuries in the left leg were noted. Her radiographs and physical examination verified the above signs. Unstable pelvic fractures, multiple fractures of bilateral lower limbs with floating knee injury, multiple pelvic and rib fractures and multiple degloving injuries and soft tissue contusion formed the characteristics of the multiple-injury. The algorithm of DCO was determined as the treatment. Early simplified procedures such as wound debridement, pelvis fixation, closed reduction and EF of the right shoulder joint, and chest wall fixation were conducted as soon as possible. After a period of time, internal fixations were applied to the fracture sites. The subsequent functional exercise was also conducted in accordance with this algorithm. This patient got recovery after the treatments which were guided by the criterion of DCO. The restoration of limb functional and the quality of life greatly improved. The DCO plays a decisive role in the first aid and follow-up treatment of this patient. The guidelines of management of complex pelvic ring injuries and floating knee should be established by authorities.

Pelvic-fracture urethral injury in children

2015-01-01

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

We retrospectively reviewed the results of 3 types of initial management of pelvic fracture urethral disruption in children. From 1980 to 1994, 35 boys 2 to 15 years old (mean age 8.1) with prostatomembranous urethral disruption were treated, including 17 who also had associated injuries. Immediate treatment included suprapubic cystostomy and delayed urethroplasty in 19 patients (group 1), urethral catheter alignment without traction and concomitant suprapubic cystostomy in 10 (group 2), and primary retropubic anastomotic urethroplasty in 6 (group 3). In all patients in groups 1 and 2 severe urethral obliteration developed. Four group 3 patients (66%) had a stricture at the site of anastomotic repair. After delayed urethroplasty 16 group 1 (84%) and all 10 group 2 patients were continent. However, only 3 group 3 patients (50%) achieved continence. Retrospectively associated bladder neck injury occurred in 5 of the 6 incontinent boys. Erections were observed before and after treatment in all but 3 children. Unstable pelvic ring fractures (type IV) comprised 28% of all pelvic fractures with a high rate of associated injuries. As described, urethral alignment was not beneficial for avoiding urethral obliteration. Therefore we recommend suprapublic cystostomy as the only form of initial treatment in these cases. Urinary incontinence seems more likely related to associated bladder neck rupture and the severity of pelvic fracture rather than to initial treatment or delayed urethral repair. Consequently, when associated bladder neck injury is present, we advocate immediate surgical repair.

The posterior urethra pierces the perineal diaphragm in close relationship to the pubic arc elements of the bony pelvis to which it is tethered by attachments to the puboprostatic ligaments and the perineal membrane. Because of these relationships, it is not surprising that fracture disruptions of the pelvic ring can be associated with injuries to the urethra at this level. Although the relationship between pelvic fracture and posterior urethral injury has been recognized for >1 century, considerable controversy exists on almost any aspect of these injuries, from the anatomy and classification of the injuries to the strategies for acute management, reconstruction, and treatment of complications, to mention just a few. What it is not controversial and well known is that these injuries can result in significant morbidity in the long run--mainly strictures, erectile dysfunction, and urinary incontinence--which can cause lifelong disability. It also well known that, just as in many other areas of trauma, the severity and duration of the complications can be reduced considerably if the injury is diagnosed and treated promptly and efficiently. This chapter summarizes the most relevant published evidence about the management of pelvic fracture urethral injuries. This comprehensive review, performed by an international panel of experts, will provide valuable information and recommendations to help urologists worldwide improve the treatment and outcomes of their injured patients.

Open pelvic fractures associated with rectal injuries are uncommon. They often cause serious pelvic infection, even death. This combination of injuries has been reviewed infrequently. Herein, we report factors associated with pelvic infection and death in a group of patients with open pelvic fractures and concurrent rectal injuries. We retrospectively reviewed the records of patients with open pelvic fractures and rectal injuries who were treated at our institution from January 2010-April 2014. From the medical records, age, gender, Injury Severity Score (ISS), cause of fracture, associated injuries, classification of the fracture, degree of soft-tissue injury, Glasgow Coma Score (GCS), Revised Trauma Score (RTS), packed red blood cells (PRBCs) needed, presence/absence of shock, early colostomy (yes or no), drainage (yes or no), and rectal washout (yes or no) were extracted. Univariable and multivariable analysis were performed to determine the association between risk factors and pelvic infection or death. Twenty patients were identified. Pelvic infection occurred in 50% (n = 10) of the patients. Four patients suffered septicemia, and three patients died of multiple organ dysfunction. The mortality rate thus was 15%. According to the univariable analysis, the patients in whom pelvic infection developed had shock, RTS ≤8, GCS ≤8, blood transfusion ≥10 units in the first 24 h, no colostomy, or Gustilo grade III soft-tissue injury. According to the multivariable analysis, shock and absence of colostomy were independently associated with pelvic infection. By univariable analysis, the only factor associated with death was RTS ≤8. The incidence of pelvic infection was lower in patients having early colostomy (p < 0.05). Patients with shock had a higher risk of pelvic infection, and we recommend aggressive measures to treat these patients. According to our results, RTS ≤8 could be a predictor of poor outcomes in patients with open pelvic fracture and

Pelvic ring fractures (PRFs) are a major cause of morbidity and mortality in motor vehicle collisions (MVCs). Understanding the factors leading to PRFs may help improve vehicle design and safety. This study sought to determine the vehicular, crash, and occupant characteristics that contribute to PRFs. From 1997 to 2003, 240 adult patients involved in lateral or frontal crashes were prospectively studied. Comprehensive crash reconstructions, vehicle analysis, and occupant data were compiled and analyzed as part of the national Crash Injury Research Engineering Network project. Of 240 study patients, 38 had PRFs. The incidence of PRFs was significantly associated with female gender, lateral impact crashes, vehicle incompatibility, and severity of crash. Seat belts and airbags were not protective against PRFs in either lateral or frontal crashes. All vehicles in the current study were less than 6 years old at the time of the MVC and thus reflect newer safety designs. Compared with studies of PRFs in MVCs before the widespread adoption of modern safety standards, our series suggests there has been a modest decrease in the incidence of PRFs in newer vehicles. Current safety standards do not adequately protect against PRFs, especially in lateral MVCs involving incompatibility and female occupants. New technology needs to be developed and implemented. Our data suggest that side impact airbags, alteration of vehicle geometry, and increased reinforcement of side panels and doors may result in fewer PRFs.

Debate remains over the role of surgical treatment in minimally displaced lateral compression (Young-Burgess, LC, OTA 61-B1/B2) pelvic ring injuries. Lateral compression type 1 (LC1) injuries are defined by an impaction fracture at the sacrum; type 2 (LC2) are defined by a fracture that extends through the posterior iliac wing at the level of the sacroiliac joint. Some believe that operative stabilization of these fractures limits pain and eases mobilization, but to our knowledge there are few controlled studies on the topic. (1) Does operative stabilization of LC1 and LC2 pelvic fractures decrease patients' narcotic use and lower their visual analog scale pain scores? (2) Does stabilization allow patients to mobilize earlier with physical therapy? This retrospective study of LC1 and LC2 fractures evaluated patients treated definitively at one institution from 2007 to 2013. All patients treated surgically, all nonoperative LC2, and all nonoperative LC1 fractures with complete sacral injury were included. In general, LC1 or LC2 fractures with greater than 10 mm of displacement and/or sagittal/axial plane deformity on static radiographs were treated surgically. One hundred fifty-eight patients in the LC1 group (107 [of 697 screened] nonoperative, 51 surgical) and 123 patients in the LC2 group (78 nonoperative, 45 surgical) met inclusion criteria. The surgical and nonoperative groups were matched for fracture type. To account for differences between patients treated surgically and nonoperatively, we used propensity modeling techniques incorporating treatment predictors. Propensity scores demonstrated good overlap and were used as part of multiple variable regression models to account for selection bias between the surgically treated and nonoperative groups. Patient-reported pain scores and narcotic administration were tallied in 24-hour increments during the first 24 hours of hospitalization, at 48 hours after intervention, and in the 24 hours before discharge.

To study the association of solid organ injuries (SOIs) in patients with concurrent rib and pelvic fractures. Retrospective analysis of prospectively collected data from November 2007 to May 2010. Patients' demographics, mechanism of injury, Injury severity scoring, pelvic fracture, and SOIs were analyzed. Patients with SOIs were compared in rib fractures with and without pelvic fracture. The study included 829 patients (460 with rib fractures ± pelvic fracture and 369 with pelvic fracture alone) with mean age of 35 ± 12.7 years. Motor vehicle crashes (45%) and falls from height (30%) were the most common mechanism of injury. The overall incidence of SOIs in this study was 22% (185/829). Further, 15% of patient with rib fractures had associated pelvic fracture. SOI was predominant in patients with concurrent rib fracture and pelvic fracture compared to ribs or pelvic fractures alone (42% vs. 26% vs. 15%, respectively, p = 0.02). Concurrent multiple rib fractures and pelvic fracture increases the risk of SOI compared to either group alone. Lower RFs and pelvic fracture had higher association for SOI and could be used as an early indicator of the presence of SOIs. Copyright © 2013 Surgical Associates Ltd. Published by Elsevier Ltd.

Reduction and temporary stabilization of Tile C pelvic ring injuries using a posteriorly based external fixation system.

PubMed

Martin, Murphy P; Rojas, David; Mauffrey, Cyril

2018-07-01

Tile C pelvic ring injuries are challenging to manage even in the most experienced hands. The majority of such injuries can be managed using percutaneous reduction techniques, and the posterior ring can be stabilized using percutaneous transiliac-transsacral screw fixation. However, a subgroup of patients present with inadequate bony corridors, significant sacral zone 2 comminution or significant lateral/vertical displacement of the hemipelvis through a complete sacral fracture. Percutaneous strategies in such circumstances can be dangerous. Those patients may benefit from prone positioning and open reduction of the sacral fracture with fixation through tension band plating or lumbo-pelvic fixation. Soft tissue handling is critical, and direct reduction techniques around the sacrum can be difficult due to the complex anatomy and the fragile nature of the sacrum making clamp placement and tightening a challenge. In this paper, we propose a mini-invasive technique of indirect reduction and temporary stabilization, which is soft tissue friendly and permits maintenance of reduction during definitive fixation surgical.

Incidence of urethral disruption in females with traumatic pelvic fractures.

Carter, C T; Schafer, N

1993-05-01

According to the National Center for Health Statistics, in 1986 1.4 million female patients in the United States were admitted to inpatient and short-stay nonfederal hospitals as a result of injuries acquired secondary to trauma. Of these, 45,000 had traumatic pelvic fractures. Rupture of the urethra is the most important lower urinary tract injury associated with traumatic pelvic fracture because of the high incidence of serious complications, such as urethral stricture and incontinence. To our knowledge, there are no satisfactory studies in the English literature documenting the incidence of urethral disruption in females with traumatic pelvic fractures. The records of all women patients with pelvic fractures registered in the Latter Day Saints Hospital trauma registry between July 1, 1981 and August 31, 1987 were reviewed. Of 146 female patients with traumatic pelvic fractures who were hospitalized during this period, none was found to have an urethral injury. Two patients (1.4%) had bladder contusions, and one (.7%) had a bladder rupture. This was the first large series attempting to identify the true incidence of urethral disruption in females with traumatic pelvic fracture, and it was found to be a rare occurrence.

Urological injuries in pelvic fractures are noticed in 6-15% of the cases. The bladder, due to its anatomical position, is prone to rupture in pelvic fractures. The majority of urinary bladder injuries are either extraperitoneal or intraperitoneal. Nonetheless, both types can occur simultaneously in 6% of the cases. A 45-year-old male was brought to our emergency department after being struck by an automobile. In the absence of signs of urethral injury, a Foley's catheter was inserted revealing gross hematuria. The radiological assessment showed bilateral non-displacement sacral wing fractures, bilateral non-displacement anterior column fractures and bilateral comminuted superior and inferior pubic rami fractures, with a detached pubic bone fragment displaced posteriorly. A CT cystogram was performed showing intraperitoneal and extraperitoneal extravasation of contrast. The patient was taken to surgery. A sharp-edged bony fragment was discovered inside the bladder. A two-layer closure of the bladder was performed. Pelvic fractures with concomitant lower urinary tract injuries are associated with high morbidity and mortality. The signs indicative of bladder rupture include a more than one centimeter diastasis of the symphysis pubis and a displaced fracture of more than one centimeter involving the obturator ring. However, the signs may not be present as in our case. This unusual case illustrates the potential risk of bladder injury following stable pelvic fractures through a detached bone segment. It also emphasizes on having a high index of suspicion. The teamwork and multidisciplinary approach are essential for an optimal outcome. Copyright © 2016 The Authors. Published by Elsevier Ltd..

Associated urological and orthopedic injuries of the pelvic ring are complex with numerous potential complications. These patients are treated optimally using a team approach. The combined expertise is not only helpful initially when managing these difficult patients, but also later as problems develop. This study describes a treatment protocol and reports the early results of 23 patients with unstable pelvic fractures and associated bladder or urethral disruptions, or both, treated surgically with open reduction and internal fixation of the anterior pelvic ring injuries at the same anesthetic and using the same surgical exposure as the urethral realignments or bladder repairs or both. Early complications occurred in four patients (17%): one patient sustained a fifth lumbar nerve injury caused by the pelvic reduction procedure, and three patients had anterior pelvic internal fixation failures. Late complications occurred in eight patients (35%). There was one deep wound infection (4.3%) that presented 6 weeks after injury. Late urological complications occurred in seven patients (30%). Four of the nine male patients with urethral disruptions had urethral stricture after their primary urethral realignments (44%). Three of the 18 male patients admitted to impotence (16.7%). One of the three had a residual thoracic paraplegia caused by a burst fracture. One of the five female patients had urinary incontinence and required a bladder suspension operation to restore normal function (20%). A low infection rate can be expected despite the use of internal fixation. Early urethral "indirect" realignments avoid more difficult delayed open repairs; however, late urological complication rates are still high. Early "direct" bladder repairs are easily performed at the time of anterior pelvic open reduction and internal fixation. Suprapubic tubes are not necessary to adequately divert the urine when large diameter urethral catheters are used in these patients.

Pelvic fracture and associated urologic injuries.

PubMed

Brandes, S; Borrelli, J

2001-12-01

Successful management of patients with major pelvic injuries requires a team approach including orthopedic, urologic, and trauma surgeons. Each unstable pelvic disruption must be treated aggressively to minimize complications and maximize long-term functional outcome. Commonly associated urologic injuries include injuries of the urethra, corpora cavernosa (penis), bladder, and bladder neck. Bladder injuries are usually extraperitoneal and result from shearing forces or direct laceration by a bone spicule. Posterior urethral injuries occur more commonly with vertically applied forces, which typically create Malgaigne-type fractures. Common complications of urethral disruption are urethral stricture, incontinence, and impotence. Acute urethral injury management is controversial, although it appears that early primary realignment has promise for minimizing the complications. Impotence after pelvic fracture is predominantly vascular in origin, not neurologic as once thought.

The prevalence of osteoporosis has continuously increased over the past decades and it is set to increase substantially as life expectancy rises steadily. Fragility or osteoporotic fractures of the pelvis often occur after low energy falls e.g. from standing, however, some patients present with assumed insufficiency fractures of the pelvis without a previous trauma. Osteoporotic fractures impose a tremendous economic burden and these fractures deserve attention as they lead to a decrease in mobility with an increase in dependency and are associated with a high rate of mortality. To date, little is known about potential risk factors for pelvic insufficiency fractures. Furthermore, information on clinical outcome is scarce. In view of this rather limited knowledge, we aimed to identify potential risk factors for pelvic insufficiency fractures and to collect information on their short- and long-term outcomes. Files of all consecutive patients admitted between January 2010 and December 2013 for a pelvic insufficiency fracture were enrolled in this study. Pelvic fractures that occurred on tumorous bone or after high-energy trauma were excluded. Fractures of the pelvis included all pelvic bones except the coccyx. For all patients, we recorded clinical and biological parameters available from their medical history. For comparison, the same biological and clinical parameters were evaluated in an age matched control group of 1083 patients aged over 70 who were admitted to our orthopaedic department to undergo knee or hip arthroplasty. The statistical analyses used or Fisher test for percentages comparison, 2-tailed t-tests and Mann Whitney for mean comparison. To determine what factors are predictors and what factors are confounders of pelvic insufficiency fractures, multivariate linear regression analysis using the fracture as a continuous variable was performed. Ninety-three patients with a pelvic insufficiency fracture were identified. Following the Rommens and Hofmann

Pelvic crescent fractures: variations in injury mechanism and radiographic pattern.

Gehlert, Rick J; Xing, Zhiqing; DeCoster, Thomas A

2014-01-01

Pelvic crescent fracture, also known as sacroiliac fracture-dislocation, is traditionally considered as a lateral compression injury and a vertically stable injury. Thirty consecutive cases were analyzed and it was found that 63% of cases were caused by lateral compression (LC), 27% by anteroposterior compression (APC), and 10% by vertical shear (VS). APC and VS injuries cause significant displacement of the anterior iliac fragment, but 21% of LC injury cases showed minimal displacement and were treated successfully with nonoperative treatment. Different injury mechanisms also produce different types of pelvic instability. More important, different injury mechanisms produce distinct radiographic fracture patterns regarding the obliquity of the fracture line and fracture surface. These differences in the fracture pattern will influence the decision of internal fixation options. Therefore, treatment of pelvic crescent fractures should be based on individual analysis of injury mechanism and radiographic fracture pattern.

The early diagnosis of pelvic arterial haemorrhage is challenging for initiating treatment by transcatheter arterial embolization (TAE) in multiple trauma patients. We use an institutional algorithm focusing on haemodynamic status on admission and on a whole-body CT scan in stabilized patients to screen patients requiring TAE. This study aimed to assess the effectiveness of this approach. This retrospective cohort study included 106 multiple trauma patients admitted to the emergency room with serious pelvic fracture [pelvic abbreviated injury scale (AIS) score of 3 or more]. Of the 106 patients, 27 (25%) underwent pelvic angiography leading to TAE for active arterial haemorrhage in 24. The TAE procedure was successful within 3h of arrival in 18 patients. In accordance with the algorithm, 10 patients were directly admitted to the angiography unit (n=8) and/or operating room (n=2) for uncontrolled haemorrhagic shock on admission. Of the remaining 96 stabilized patients, 20 had contrast media extravasation on pelvic CT scan that prompted pelvic angiography in 16 patients leading to TAE in 14. One patient underwent a pelvic angiography despite showing no contrast media extravasation on pelvic CT scan. All 17 stabilized patients who underwent pelvic angiography presented a more severely compromised haemodynamic status on admission, and they required more blood products during their initial management than the 79 patients who did not undergo pelvic angiography. The incidence of unstable pelvic fractures was however comparable between the two groups. Overall, haemodynamic instability and contrast media extravasation on the CT-scan identified 26 out of the 27 patients who required subsequent pelvic angiography leading to TAE in 24. An algorithm focusing on haemodynamic status on arrival and on the whole-body CT scan in stabilized patients may be effective at triaging multiple trauma patients with serious pelvic fractures.

To design minimal invasive screw on posterior pelvic ring and perform threedimensional finite element analysis based on a pelvis finite element model. We measured the pelvic anatomical data of 20 healthy volunteers and identified potential designs for minimal invasive screw on posterior pelvic ring. A finite element model of pelvis was then established. Threedimensional finite element analyses were performed under static and dynamic mechanical loading,respectively. Three screw tracks on ilium (A,B and C) were identified based on a threedimensional reconstruction of pelvis. Nail track B and C had greater length and width,but shorter distance between nailing and soft tissue compared with nail track A. Static loading under an external rotation load of 500 N generated a maximum Mises Von stress of 582.05 Pa and sacral iliac complex of 107.38 Pa. The greatest strain was located at the articular cartilage on the side of the nail,followed by lateral sacral joint cartilage and symphysis pubis. The largest displacement was located at the ilium on the side of the nail,with a gradient decrease to the opposite side. The largest displacement of the anterior superior iliac spine was 0.35 cm on the side of the nail. The dynamic loading identified displacement of the anterior superior iliac spine with 1.5 mm in Z axis,1.8 mm in X axis and -0.2 mm in Y axis; and displacement of the pubic bone with 0.8 mm in Z axis,1.0 mm in X axis and 0.03 mm in Y axis. The maximum displacement appeared along the impact direction: Y axis. Relatively large equivalent stress was found in pubis and ischium,anterior superior iliac spine,sacrum,acetabular that are prone to fracture. With increased impact force,the stress of pelvis increased over time. The maximum impact force,stress and displacement of the pelvis occurred at 10 ms when peak force was reached. Under the impact of 4 000 N and 5 000 N,the bone was subject to a stress level of over 200 MPa,exceeding its average yield strength,which suggests

Surgical treatment of pelvic ring injuries requires in-depth knowledge of the topographic anatomy of the pelvic bones, joints and soft tissue structures. A wide range of stabilizing techniques is available including bridging plate osteosynthesis, iliosacral compression screw osteosynthesis and transpubic positioning screws. In this article the different treatment strategies with the respective surgical approaches and patient positioning for pelvic ring fractures and combined lesions of the pelvic ring and acetabulum are presented. Pelvic ring lesions with rotational instability are approached from the anterior and occasionally from both the anterior and posterior based on the amount and localization of the instability. In vertically unstable lesions the most unstable part must be addressed first by reduction and fixation of the dislocated part to the axial skeleton. In combined fractures of the pelvis and acetabulum dorsal stabilization is carried out first.

To evaluate the early operative treatment and clinical results of pelvic fractures associated with urethra disruption. From January 1995 to January 2005, 25 patients suffered from pelvic fractures combined urethra disruption treated by operation were retrospectively analyzed. According to Tile's classification, 1 case was stable pelvic fracture, 17 rotational unstable fractures, and 7 rotational combined vertical unstable fractures. The complete urethra rupture were in 23 cases and incomplete in 2 cases. The operative methods included: (1) emergency open reduction and internal fixation of the pelvis combined primary urethra suturing in 2 cases, partial suturing after realignment in 4 cases, realignment in 2 cases, and urethrovaginal penetrating wound repairing in 1 case; (2) primary urethra realignment only and delayed (range, 7 to 21 days) pelvic internal fixation in 10 cases; (3) early cystostomy and delayed (range, 3 to 21 days) urethra realignment and pelvic internal fixation in 6 cases. The mean follow-up time of all patients was 34 months (range from 6 to 120 months). According to Majeed's evaluation, 17 cases of pelvic injury showed excellent results, 5 good, and 3 fare. After urinary catheter removed, the mean maximal urine flow rate of 19 (76%) patients was 18.6 ml/s and the mean scar length between both disrupted ends on the film of excretion urethrography was 0.51 cm. Five (20%) cases suffered in dysuria needed urethral dilatation or further surgery. One (4%) female could not control urination who need a second-look operation. The primary suprapubic soft tissue avulsion wound infection secondary to retropubic abscess was found in 1 case, posterior urethra-stenosis in 5 cases, sexual impotence in 3 cases, and incontinence in 1 case. The satisfactory reduction and effective fixation of the pelvic fractures is an anatomical basis for receiving "tension-free urethral anastomosis".

Pelvic fractures are severe injuries with frequently associated multi-system trauma and a high mortality rate. The value of the pelvic fracture pattern for predicting transfusion requirements and mortality is not entirely clear. To address hemorrhage from pelvic injuries, the early application of pelvic binders is now recommended and arterial angio-embolization is widely used for controlling arterial bleeding. Our aim was to assess the association of the pelvic fracture pattern according to the Tile classification system with transfusion requirements and mortality rates, and to evaluate the correlation between the use of pelvic binders and arterial angio-embolization and the mortality of patients with pelvic fractures. Single-center retrospective cohort study including all consecutive patients with a pelvic fracture from January 2008 to June 2015. All radiological fracture patterns were independently reviewed and grouped according to the Tile classification system. Data on patient demographics, use of pelvic binders and arterial angio-embolization, transfusion requirements and mortality were extracted from the institutional trauma registry and analyzed. The present study included 228 patients. Median patient age was 43.5 years and 68.9% were male. The two independent observers identified 105 Tile C (46.1%), 71 Tile B (31.1%) and 52 Tile A (22.8%) fractures, with substantial to almost perfect interobserver agreement (Kappa 0.70-0.83). Tile C fractures were associated with a higher mortality rate (p = 0.001) and higher transfusion requirements (p < 0.0001) than Tile A or B fractures. Arterial angio-embolization for pelvic bleeding (p = 0.05) and prehospital pelvic binder placement (p = 0.5) were not associated with differences in mortality rates. Tile C pelvic fractures are associated with higher transfusion requirements and a higher mortality rate than Tile A or B fractures.

Open pelvic fracture is a rare injury. Our aim in this study is to systematically review the literature to define when diverting colostomy is indicated to protect the patient from infection in open blunt pelvic fractures. Papers studying open pelvic fractures and the use of colostomy were retrieved through MEDLINE and PUBMED. The papers were critically appraised regarding their methodology and conclusions. Relevant information was combined. The level of evidence for the use of colostomy in open pelvic fractures is very low. All reports are retrospective and no statistical methods have been used to support conclusions drawn. We found no difference in the overall infectious complication rate between the colostomy and noncolostomy groups. There is an assumption that patients with perineal wounds would benefit from colostomy; however, rectal involvement in these injuries was not detailed. The role of colostomy in open blunt pelvic fractures is unresolved and randomized multicenter trials are needed.

Increased fracture displacement has previously been described with the application of pelvic circumferential compression devices (PCCDs) in patients with lateral compression-type pelvic fracture. We describe the first reported case of hemodynamic deterioration temporally associated with the prehospital application of a PCCD in a patient with a complex acetabular fracture with medial displacement of the femoral head. Active hemorrhage from a site adjacent to the acetabular fracture was subsequently demonstrated on angiography. Caution in the application of PCCDs to patients with lateral compression-type fractures is warranted. Copyright © 2017 Air Medical Journal Associates. All rights reserved.

Minimal Invasive Surgical Treatment of Fragility Fractures of the Pelvis.

Rommens, Pol Maria; Wagner, Daniel; Hofmann, Alex

The incidence of fragility fractures of the pelvis is increasing quickly. The characteristics of these fractures are different from pelvic ring disruptions in adults. Fragility fractures of the pelvis are the consequence of a low-energy trauma which occurs in a patient with an important decrease of bone mineral density. Due to a consistent pattern of alteration of bone mass distribution in the sacrum, other fracture morphologies occur than in younger adults. The leading symptom is immobilizing pain in the lower back, in the buttocks, in the inguinal region and/or at the pubic symphysis. Conventional radiographs and CT will show the presence and localization of the fractures in the anterior and posterior pelvic ring. A new, comprehensive classification system distinguishes four categories of instability. This first criterion is most important, because it also gives hints for the preferred type of treatment. The second criterion, leading to the subtypes in the four categories, is the localization of the instability in the posterior pelvic ring. This criterion points the way towards the type of the surgical procedure to be used. When a surgical treatment is chosen, the procedure should be as minimal invasive as possible. Different techniques for percutaneous or less invasive fixation of the posterior pelvic ring have been developed. Their advantages and limitations are presented: sacroplasty, iliosacral screw osteosynthesis, cement augmentation, transiliac internal fixation, trans-sacral osteosynthesis, lumbopelvic fixation. Fractures of the anterior pelvic ring also need special attention. Retrograde transpubic screw fixation is recommended for pubic rami fractures. Fractures of the pubic body and instabilities of the pubic symphysis need bridging plate osteosynthesis. We do not recommend anterior pelvic external fixation in elderly because of the risk of pin track infection and pin loosening. Celsius.

To evaluate the usefulness of coagulation biomarkers, which are easy and quick to analyze in emergency settings, for prediction of arterial extravasation due to pelvic fracture. The medical records of pelvic fracture patients transferred to the emergency department of Gunma University Hospital between December 2009 and May 2015 were reviewed. Patients were divided into two groups, those with (Extra(+)) and without (Extra(-)) arterial extravasation on enhanced CT or angiography. Levels of fibrin degradation products (FDP), D-dimer, fibrinogen, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, systolic blood pressure, heart rate, the Glasgow Coma Scale, pH, base excess, hemoglobin and lactate levels, the pattern of pelvic injury, and injury severity score were measured at hospital admission, and compared between the two groups. Parameters with a significant difference between the two groups were used to construct receiver operating characteristic (ROC) curves. The study included 29 patients with pelvic fracture. FDP, D-dimer, the ratio of FDP to fibrinogen and the ratio of D-dimer to fibrinogen were the most useful parameters for predicting arterial extravasation due to pelvic fracture. FDP, D-dimer, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, and hemoglobin and lactate levels were significantly higher in the Extra(+) group than in the Extra(-) group (FDP, 354.8μg/mL [median] versus 96.6μg/mL; D-dimer, 122.3μg/mL versus 42.1μg/mL; the ratio of FDP to fibrinogen, 3.39 versus 0.42; the ratio of D-dimer to fibrinogen, 1.14 versus 0.18; hemoglobin, 10.5g/dL versus 13.5g/dL; lactate, 3.5mmol/L versus 1.7mmol/L). The area under the ROC curves for FDP, D-dimer, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, hemoglobin and lactate levels were 0.900, 0.882, 0.918, 0.900, 0.815 and 0.765, respectively.

To review pelvic fracture urethral injuries in women, generally regarded as rare and thus discussed infrequently. Twelve patients (age range 7-51 years) with such injuries were reviewed; most had associated injuries, generally more severe than seen in males with urethral injuries. Patients with milder injuries, perhaps damaging just the innervation of the urethra, presented with incontinence; more severe injuries seemed to cause a longitudinal tear in the urethra but again patients presented mainly with incontinence problems. The most severe injuries were associated with complete rupture of the urethra and a distraction defect suggesting an avulsion injury. These problems were difficult to treat both reconstructively and in providing continence. Pelvic fracture urethral injuries occur in females, but less often than in males. The female urethra seems relatively resistant to injury; differing degrees of severity of pelvic trauma cause different types of urethral injury but in general, a more severe injury is needed to damage it than is necessary in males.

Dislocated pelvic fractures which require surgical repair are usually operated on via open surgery. Approach-related morbidity is reported with a frequency of up to 30%. The aim of this anatomical study was to prove the feasibility of endoscopic visualisation of the relevant anatomical structures in pelvic surgery and to perform completely endoscopic plate osteosynthesis of the acetabulum with available standard laparoscopic instruments. In four human cadavers, we established an endoscopic preparation of the complete pelvic ring, from the symphysis to the iliosacral joint, including the quadrilateral plate and the sciatic nerve, and performed endoscopic plate osteosynthesis along the iliopectineal line. The endoscopic preparation of the complete pelvic ring and the quadrilateral plate was demonstrated step-by-step, followed by completely endoscopic plate osteosynthesis along the pelvic brim. Endoscopic, radiographic, and schematic pictures are used to illustrate the technique. The completely endoscopic preparation of the pelvic brim and the quadrilateral plate is feasible with available standard laparoscopic instruments. Moreover, plate osteosynthesis could be performed endoscopically. Further research on reduction techniques is necessary when planning to implement this technique into a clinical scenario.

Pelvic ring fractures are common in the elderly population and are usually a result of low-energy trauma, such as falls from standing. In most cases, low-energy pelvic ring injuries can be treated with appropriate analgesia and early mobilization. Arterial injury resulting in hemodynamic instability from a low-energy pelvic ring injury is rare but, given the poor compliance of vessels in the elderly population, possible. These patients must be carefully monitored after the initial injury. The purpose of this report is to describe an elderly patient who sustained a superior pubic ramus fracture and arterial injury following a low-energy fall from standing that required angiographic intervention. Elderly patients who sustain low-energy or pelvic insufficiency fractures are unlike the younger population with high-energy pelvic fractures and hemodynamic collapse. Elderly patients can have a delayed presentation of arterial injury and require careful physical examination and close monitoring. Additionally, the authors provide a review of the literature for low-energy pelvic fractures. [Orthopedics. 2017; 40(3):e546-e548.]. Copyright 2017, SLACK Incorporated.

Epidemiological data about pelvic fractures are limited. Until today, most studies only analyzed inpatient data. The purpose of this study was to estimate incidence rates of pelvic fractures in the German population aged 60 years or older, based on outpatient and inpatient data. We conducted a retrospective population-based observational study based on routine data from a large health insurance company in Germany. Age and sex-specific incidence rates of first fractures between 2008 and 2011 were calculated. We also standardized incidence rates with respect to age and sex in the German population. Multiple Poisson regression models were used to evaluate the association between the risk of first pelvic fracture as outcome and sex, age, calendar year and region as independent variables. The total number of patients with a first pelvic fracture corresponded to 8,041 and during the study period 5,978 insured persons needed inpatient treatment. Overall, the standardized incidence rate of all first pelvic fractures was 22.4 [95% CI 22.0-22.9] per 10,000 person-years, and the standardized incidence rate of inpatient treated fractures 16.5 [16.1-16.9]. Our adjusted regression analysis confirmed a significant sex (RR 2.38 [2.23-2.55], p < 0.001, men as reference) and age effect (higher risk with increasing age, p < 0.001) on first fracture risk. We found a slight association between calendar year (higher risk in later years compared to 2008, p = 0.0162) and first fracture risk and a further significant association with region (RR 0.92 [0.87-0.98], p = 0.006, Westfalen-Lippe as reference). The observed incidences are considerably higher than incidences described in the international literature, even if only inpatient treated pelvic fractures are regarded. Besides which, non-inclusion of outpatient data means that a relevant proportion of pelvic fractures are not taken into account. Prevention of low energy trauma among older people remains an important issue.

Study Design: Literature review. Objective: The aim of this review is to describe the injuries associated with sacral fractures and to analyze their impact on patient outcome. Methods: A comprehensive narrative review of the literature was performed to identify the injuries associated with sacral fractures. Results: Sacral fractures are uncommon injuries that result from high-energy trauma, and that, due to their rarity, are frequently underdiagnosed and mistreated. Only 5% of sacral fractures occur in isolation. Injuries most often associated with sacral fractures include neurologic injuries (present in up to 50% of sacral fractures), pelvic ring disruptions, hip and lumbar spine fractures, active pelvic/ abdominal bleeding and the presence of an open fracture or significant soft tissue injury. Diagnosis of pelvic ring fractures and fractures extending to the lumbar spine are key factors for the appropriate management of sacral fractures. Importantly, associated systemic (cranial, thoracic, and abdominopelvic) or musculoskeletal injuries should be promptly assessed and addressed. These associated injuries often dictate the management and eventual outcome of sacral fractures and, therefore, any treatment algorithm should take them into consideration. Conclusions: Sacral fractures are complex in nature and often associated with other often-missed injuries. This review summarizes the most relevant associated injuries in sacral fractures and discusses on their appropriate management. PMID:28989838

The main causes of death in patients with open pelviperineal injuries are uncontrollable bleeding and pelvic sepsis. The aim of this study was to evaluate the management outcomes of open pelvic fractures associated with extensive perineal injuries. We retrospectively studied 15 cases with open pelvic fractures associated with extensive perineal injuries (urethral and anal canal laceration) admitted between August 2006 and September 2010. Mechanism of injury, Injury Severity Score, associated injuries, hemodynamic status on arrival, resuscitation and transfusion requirements, operative techniques, intra- and postoperative complications, length of intensive care unit and hospital stay, and mortality were recorded in a computerised database for further evaluation and analysis. The male to female ratio was 12:3 with an average age of 38.6 years (ranged, 11 to 65 years). The average packed red blood cell units used were 8 units (ranged, 4 to 21 units). All patients were initially transferred to the operating room for colostomy, radical debridement and fixation of the pelvic fracture by an external fixator. One patient had acute renal failure, which improved with medical treatment and 2 patients (13.3%) died, one with type III anteroposterior compression fracture due to hemorrhagic shock and the other due to septicemia. Open pelvic fractures with extensive perineal injuries are associated with high mortality rates. Early diagnosis and appropriate treatment, including reanimation, colostomy, cystostomy, vigorous and repeated irrigation and debridement, and fixation by an external fixator can improve the outcomes and reduce the mortality rate.

To investigate the application and effect of minimally invasive percutaneous anterior pelvic pubic ramus screw fixation in Tile B fractures. A retrospective review was conducted on 56 patients with posterior pelvic ring injury combined with fractures of anterior pubic and ischiadic ramus treated between May 2010 and August 2015, including 31 males and 25 females with an average age of 36.8 years old ranging from 35 to 65 years old. Based on the Tile classification, there were 13 cases of Tile B1 type, 28 cases of Tile B2 type and 15 cases of Tile B3 type. Among them, 26 patients were treated with sacroiliac screws combined with external fixation (external fixator group) and the other 30 patients underwent sacroiliac screw fixation combined with anterior screw fixation (pubic ramus screw group). Postoperative complications, postoperative ambulation time, fracture healing, blood loss, Majeed pelvic function score and visual analogue scale(VAS) were compared between two groups. Fifty-four patients were followed up from 3 to 24 months with a mean of 12 months. There were no significant difference in the peri-operative bleeding and operation time between two groups( P >0.05). The postoperative activity time and fracture healing time of pubic ramus screw group were shorter than those of the external fixator group, the differences were statistically significant( P <0.05). The Majeed score, VAS score of pubic ramus screw group were higher than those of the external fixator group, the differences were statistically significant( P <0.05). The incidence of postoperative complications of pubic ramus screw was lower than that of the external fixator group, the difference was statistically significant ( P <0.05). Percutaneous iliosacral screws fixation combined with the pubic ramus screw is an effective and safty treatment method to the Tile B pelvic fracture. It has advantages of early ambulation, relief of the pain and few complications.

The main objective of this study was to identify demographic, clinical, analytical factors or injuries associated with 30-day mortality in patients with pelvic fractures. Prospective observational study of patients with multiple injuries including pelvic fractures between January 2009 and January 2017. We recorded demographic, clinical, and laboratory data on arrival at the emergency department; type of pelvic fracture; treatments; associated lesions; and 30-day mortality. Univariable and multivariable models were used to analyze the data. A total of 2061 multiple-injury patients were attended; 118 had pelvic fractures. Fifteen of the patients with pelvic fractures (12.7%) died within 30 days. Arterial blood pressure on admission was less than 90 mm Hg in 23.7%, heart rate was over 100 beats per minute in 41.52%, lactic acid level was 20 mg/dL or higher in 67.6%, and base excess of -6 or less was recorded for 26.3%. The mean Injury Severity Score was 20 points. Angiographic embolization was required in 80.6% and preperitoneal packing in 3.4%. The main associated lesions were rib fractures (35.6%), hemo-pneumothorax (31.3%), spinal injuries (35.6%), and head injuries (30%). The 6 independent variables associated with risk of death in multiple-injury patients with pelvic fractures are age, female sex, complex fractures (Tile type C), lactic acid level of 20 mg/dL or more, base excess of -6 or less, and bowel perforation.

There is an established association between ED and pelvic fracture urethral injuries (PFUIs). However, ED can occur after the injury and/or the urethral repair. To our knowledge, only one study of erectile function (EF) after urethroplasty for PFUIs used a validated questionnaire. This study was carried out to determine the impact of anastomotic posterior urethroplasty for PFUIs on EF. We retrospectively reviewed the computerized surgical records to identify patients who underwent anastomotic urethroplasty for PFUIs from 1998 to 2014. Those patients were contacted by phone or mail and were re-evaluated in the outpatient clinic by International Index of Erectile Function questionnaire; in unmarried men, the single-question self-report of ED was used for evaluation of EF, clinical examination and penile color Doppler ultrasonography (CDU) for men with ED. Overall, 58 patients were included in the study among whom 36 (62%) men were sexually active and the remaining 22 (38%) were single. The incidence of ED among our group is 72%. All patients developed ED after initial pelvic trauma and none of our patients had impaired EF after urethroplasty. The incidence of ED increased proportionally with severity of pelvic trauma. All patients with type-C pelvic fracture, associated symphysis pubis diastasis, sacroiliac joints diastasis and bilateral pubic ramus fractures had ED. Men with PFUIs had worse EF than men in other series with pelvic fractures without urethral injury. The majority (88%) of men with ED showed veno-occlusive dysfunction on penile CDU. So we concluded that men with PFUIs had a high incidence of ED up to 72%. Anastomotic posterior urethroplasty had no negative impact on EF and the development of ED after PFUIs was related to the severity of the original pelvic trauma. Veno-occlusive dysfunction is the commonest etiology of ED on penile CDU.

Objectives: Pelvic fracture urethral distraction defect (PFUDD) may be associated with disabling complications, such as recurrent stricture, urinary incontinence, and erectile dysfunction. In this article we review the current concepts in the evaluation and surgical management of PFUDD, including redo urethroplasty. Materials and Methods: A PubMed™ search was performed using the keywords “pelvic fracture urethral distraction defect, anastomotic urethroplasty, pelvic fracture urethral stricture, pelvic fracture urethral injuries, and redo-urethroplasty.” The search was limited to papers published from 1980 to March 2010 with special focus on those published in the last 15 years. The relevant articles were reviewed with regard to etiology, role of imaging, and the techniques of urethroplasty. Results: Pelvic fracture due to accidents was the most common etiology of PFUDD that usually involved the membranous urethra. Modern cross-sectional imaging, such as sonourethrography and magnetic resonance imaging help assess stricture pathology better, but their precise role in PFUDD management remains undefined. Surgical treatment with perineal anastomotic urethroplasty yields a success rate of more than 90% in most studies. The most important complication of surgical reconstruction is restenosis, occurring in less than 10% cases, most of which can be corrected by a redo anastomotic urethroplasty. The most common complication associated with this condition is erectile dysfunction. Urinary incontinence is a much rarer complication of this surgery in the present day. Conclusions: Anastomotic urethroplasty remains the cornerstone in the management of PFUDD, even in previously failed repairs. Newer innovations are needed to address the problem of erectile dysfunction associated with this condition. PMID:22022064

To evaluate the effect of 3D printing technology applied in the surgical treatment of pelvic fractures through the published literatures by Meta-analysis. The PubMed database, EMCC database, CBM database, CNKI database, VIP database and Wanfang database were searched from the date of database foundation to August 2017 to collect the controlled clinical trials in wich 3D printing technology was applied in preoperative planning of pelvic fracture surgery. The retrieved literatures were screened according to predefined inclusion and exclusion criteria, and quality evaluation were performed. Then, the available data were extracted and analyzed with the RevMan5.3 software. Totally 9 controlled clinical trials including 638 cases were chosen. Among them, 279 cases were assigned to the 3D printing technology group and 359 cases to the conventional group. The Meta-analysis results showed that the operative time[SMD=-2.81, 95%CI(-3.76, -1.85)], intraoperative blood loss[SMD=-3.28, 95%CI(-4.72, -1.85)] and the rate of complication [OR=0.47, 95%CI(0.25, 0.87)] in the 3D printing technology were all lower than those in the conventional group;the excellent and good rate of pelvic fracture reduction[OR=2.09, 95%CI(1.32, 3.30)] and postoperative pelvic functional restoration [OR=1.94, 95%CI(1.15, 3.28) in the 3D printing technology were all superior to those in the conventional group. 3D printing technology applied in the surgical treatment of pelvic fractures has the advantage of shorter operative time, less intraoperative blood loss and lower rate of complication, and can improve the quality of pelvic fracture reduction and the recovery of postoperative pelvic function.

Injuries to the female urethra associated with pelvic fracture are uncommon. They may vary from urethral contusion to partial or circumferential rupture. When disruption has occurred at the level of the proximal urethra, it is usually complete and often associated with vaginal laceration. We retrospectively reviewed the records of a series of girls with pelvic fracture urethral stricture and present surgical treatment to restore urethral continuity and the outcome. Between 1984 and 1997, 8 girls 4 to 16 years old (median age 9.6) with urethral injuries associated with pelvic fracture were treated at our institutions. Immediate therapy involved suprapubic cystostomy in 4 cases, urethral catheter alignment and simultaneous suprapubic cystostomy in 3, and primary suturing of the urethra, bladder neck and vagina in 1. Delayed 1-stage anastomotic repair was performed in 1 patient with urethral avulsion at the level of the bladder neck and in 5 with a proximal urethral distraction defect, while a neourethra was constructed from the anterior vaginal wall in a 2-stage procedure in 1 with mid urethral avulsion. Concomitant vaginal rupture in 7 cases was treated at delayed urethral reconstruction in 5 and by primary repair in 2. The surgical approach was retropubic in 3 cases, vaginal-retropubic in 1 and vaginal-transpubic in 4. Associated injuries included rectal injury in 3 girls and bladder neck laceration in 4. Overall postoperative followup was 6 months to 6.3 years (median 3 years). Urethral obliteration developed in all patients treated with suprapubic cystostomy and simultaneous urethral realignment. The stricture-free rate for 1-stage anastomotic repair and substitution urethroplasty was 100%. In 1 girl complete urinary incontinence developed, while another has mild stress incontinence. Retrospectively the 2 incontinent girls had had an associated bladder neck injury at the initial trauma. Two recurrent vaginal strictures were treated successfully with additional

ABSTRACTS Objective: To study the method of X-ray diagnosis of unstable pelvic fractures displaced in three-dimensional (3D) space and its clinical application in closed reduction. Five models of hemipelvic displacement were made in an adult pelvic specimen. Anteroposterior radiographs of the pelvis were analyzed in PACS. The method of X-ray diagnosis was applied in closed reductions. From February 2012 to June 2016, 23 patients (15 men, 8 women; mean age, 43.4 years) with unstable pelvic fractures were included. All patients were treated by closed reduction and percutaneous cannulate screw fixation of the pelvic ring. According to Tile's classification, the patients were classified into type B1 in 7 cases, B2 in 3, B3 in 3, C1 in 5, C2 in 3, and C3 in 2. The operation time and intraoperative blood loss were recorded. Postoperative images were evaluated by Matta radiographic standards. Five models of displacement were made successfully. The X-ray features of the models were analyzed. For clinical patients, the average operation time was 44.8 min (range, 20-90 min) and the average intraoperative blood loss was 35.7 (range, 20-100) mL. According to the Matta standards, 7 cases were excellent, 12 cases were good, and 4 were fair. The displacements in 3D space of unstable pelvic fractures can be diagnosed rapidly by X-ray analysis to guide closed reduction, with a satisfactory clinical outcome.

Current polytrauma management is multidisciplinary, with Damage Control Surgery (DCS), Damage Control Orthopaedics (DCO) and Damage Control Resuscitation (DCR) being applied in the first few hours after injury. The most severe group of polytrauma patients are those with circulatory instability and massive blood loss as a consequence of unstable pelvic fractures. In treating these patients, of crucial importance is the speed and quality of stabilisation of pelvic fracture fragments. The authors present two case reports of polytrauma patients with unstable pelvic fractures, in whom open reduction and internal fixation was performed on the anterior fracture segment through extended laparotomy in order to stop bleeding into the abdominopelvic cavity as part of the DCS approach. Key words: exsanguination, polytrauma, unstable pelvic fracture, plate fixation.

Background: Parkinson disease is a neurodegenerative disease that affects gait and postural stability, resulting in an increased risk of falling. The purpose of this study was to estimate mortality associated with demographic factors after hip or pelvic (hip/pelvic) fracture in people with Parkinson disease. A secondary goal was to compare the mortality associated with Parkinson disease to that associated with other common medical conditions in patients with hip/pelvic fracture. Methods: This was a retrospective observational cohort study of 1,980,401 elderly Medicare beneficiaries diagnosed with hip/pelvic fracture from 2000 to 2005 who were identified with use of the Beneficiary Annual Summary File. The race/ethnicity distribution of the sample was white (93.2%), black (3.8%), Hispanic (1.2%), and Asian (0.6%). Individuals with Parkinson disease (131,215) were identified with use of outpatient and carrier claims. Cox proportional hazards models were used to estimate the risk of death associated with demographic and clinical variables and to compare mortality after hip/pelvic fracture between patients with Parkinson disease and those with other medical conditions associated with high mortality after hip/pelvic fracture, after adjustment for race/ethnicity, sex, age, and modified Charlson comorbidity score. Results: Among those with Parkinson disease, women had lower mortality after hip/pelvic fracture than men (adjusted hazard ratio [HR] = 0.63, 95% confidence interval [CI]) = 0.62 to 0.64), after adjustment for covariates. Compared with whites, blacks had a higher (HR = 1.12, 95% CI = 1.09 to 1.16) and Hispanics had a lower (HR = 0.87, 95% CI = 0.81 to 0.95) mortality, after adjustment for covariates. Overall, the adjusted mortality rate after hip/pelvic fracture in individuals with Parkinson disease (HR = 2.41, 95% CI = 2.37 to 2.46) was substantially elevated compared with those without the disease, a finding similar to the increased mortality associated with a

Pelvic fractures are considered to be uncommon and difficult to treat, even in the modern medical literature. Serious and eventually life-threatening associated injuries may occur, requiring emergency abdominal, vascular or neurologic surgery. Pelvic fractures can also be managed non-operatively; however, a considerable dispute exists on the suitable management strategy. The treatment and healing of such injuries in the bioarchaeological record, is therefore of great interest for anthropological and medico-historical studies. Fractures of the pelvis are rarely reported in the anthropological literature either due to poor preservation of the innominate bone or lack of adequate examination. Here we present two cases of pelvic fractures observed on two adult male individuals from two European medieval sites. They differ in severity and in the pattern of healing. They are both adequately healed and probably had no acute life-threatening consequences, which gives us some insight into the medical knowledge and means of management of past populations.

Pelvic fractures are a marker of severe injury, mandating a thorough investigation for the presence of associated injuries. Anatomical and physiological differences between adults and children may lead to a different impact of pelvic fractures on these populations. The purpose of this study is to compare pelvic fractures between pediatric and adult blunt trauma victims, mainly regarding their severity and associated intraabdominal injuries. A retrospective study involving blunt trauma patients suffering pelvic fractures, according to the records of the Israeli National Trauma Registry. Patients included children, aged 0-14years, and adults between 15 and 64years. The presence and severity of associated injuries were assessed. Overall, 7621 patients aged 0-64years were identified with pelvic fractures following blunt trauma. The incidence of pelvic fractures in children was (0.8%), as compared to 4.3% in adults, p <0.0001. The most common mechanism of injury was motor vehicle accident (MVA) in adults, and pedestrian hit by car (PHBC) in children. About a quarter of the patients in both groups had an ISS >25. Adults sustained significantly more moderate to severe pelvic fractures (AIS≥3) than children (26.7% vs. 17.4%, p<0.0001). The overall mortality rate was similar among the two groups (5.4% in adults, 5.2% in children, p=0.7554). The only associated injury with statistically significant difference in incidence among the two groups was rectal injury (1.2% among children, 0.2% among adults, p<0.0001). Among adult patients, there was a clear correlation between the severity of pelvic fractures and the severity of concomitant splenic and hepatic injuries (p=0.026, p=0.0004, respectively). Among children, a similar correlation was not demonstrated. Adults involved in blunt trauma are more likely to sustain pelvic fractures, and these are generally more severe fractures, as compared to children suffering from blunt trauma. Nonetheless, mortality rates were found

Anterior external fixation for pelvic ring fractures has shown to effectively improve stability and reduce mortality. However, these fixators can be associated with substantial morbidity such as pin tract infection, premature loss of fixation, and decreased quality of life in patients. Recently, two new methods of subcutaneous anterior pelvic internal fixation have been developed; the INFIX and the Pelvic Bridge. These methods have the purported advantages of lower wound complications, less surgical site pain, and improved quality of life. We sought to investigate the measured distances to critical anatomic structures, as well as the qualitative and topographic differences notable during implantation of both devices in the same cadaveric specimen. The Pelvic Bridge and INFIX were implanted in eleven fresh cadavers. Distances were then measured to: the superficial inguinal ring, round ligament, spermatic cord, lateral femoral cutaneous nerve (LFCN), femoral nerve, femoral artery, and femoral vein. Observations regarding implantation and topography were also recorded. The INFIX had greater measured distances from all structures except for the LFCN, in which its proximity placed this structure at risk. Neither device appears to put other critical structures at risk in the supine position. Significant implantation and topographic differences exist between the devices. The INFIX application lacked "safety margins" concerning the LFCN in 10/11 (90.9%) specimens, while Pelvic Bridge placement lacked "safety margins" with regard to the right superficial ring (1/11, 9%) and the right spermatic cord (1/11, 9%). Both the Pelvic Bridge and INFIX lie at safe distances from most critical pelvic structures in the supine position, though INFIX application places the LFCN at risk. Copyright © 2017 Elsevier Ltd.

Acute management and outcome of multiple trauma patients with pelvic disruptions

PubMed Central

2012-01-01

Introduction Data on prehospital and trauma-room fluid management of multiple trauma patients with pelvic disruptions are rarely reported. Present trauma algorithms recommend early hemorrhage control and massive fluid resuscitation. By matching the German Pelvic Injury Register (PIR) with the TraumaRegister DGU (TR) for the first time, we attempt to assess the initial fluid management for different Tile/OTA types of pelvic-ring fractures. Special attention was given to the patient's posttraumatic course, particularly intensive care unit (ICU) data and patient outcome. Methods A specific match code was applied to identify certain patients with pelvic disruptions from both PIR and TR anonymous trauma databases, admitted between 2004 and 2009. From the resulting intersection set, a retrospective analysis was done of prehospital and trauma-room data, length of ICU stay, days of ventilation, incidence of multiple organ dysfunction syndrome (MODS), sepsis, and mortality. Results In total, 402 patients were identified. Mean ISS was 25.9 points, and the mean of patients with ISS ≥16 was 85.6%. The fracture distribution was as follows: 19.7% type A, 29.4% type B, 36.6% type C, and 14.3% isolated acetabular and/or sacrum fractures. The type B/C, compared with type A fractures, were related to constantly worse vital signs that necessitated a higher volume of fluid and blood administration in the prehospital and/or the trauma-room setting. This group of B/C fractures were also related to a significantly higher presence of concomitant injuries and related to increased ISS. This was related to increased ventilation and ICU stay, increased rate of MODS, sepsis, and increased rate of mortality, at least for the type C fractures. Approximately 80% of the dead had sustained type B/C fractures. Conclusions The present study confirms the actuality of traditional trauma algorithms with initial massive fluid resuscitation in the recent therapy of multiple trauma patients with pelvic

ligamentotaxis in 14 patients. Therefore, it is not necessary to address the ischio-acetabular fragment. In the exceptional case, the ischio-acetabular fragment was displaced as a free bone which could not be reduced by ligamentotaxis. However, reduction and internal fixation of the ischio-acetabular fragment to the posterior column for complete re-application of the hip joint onto the pelvic ring of this case was facilitated. Postoperative 2 year and 5 year follow-up showed that the fracture had healed without heterotrophic ossification or premature osteoarthrosis of the hip joint. The exceptional case had a broken plate at the anterior column of the acetabulum. Hip function was evaluated clinically using Merle D' Aubigne's hip score. All patients had a "very good score". The study showed that reconstruction of the pelvic brim by anatomical reduction and fixation of the pubo-acetabular fragment to the anterior column plays an important role in the accuracy of fracture reduction of a displaced T-shaped acetabular fracture.

Open-book pelvic fractures (OBPF) with concomitant intra-abdominal injuries carry a high morbidity and mortality; the significance of associated perineal open wound (OBPF-POW) has not been defined. We hypothesize that the presence of perineal open wounds increases morbidity, mortality, and concomitant use of hospital resources. Patients diagnosed with OBPF over a 5-year period at a Level I trauma center were identified by trauma registry review, and were retrospectively reviewed under an Institutional Review Board-approved protocol. Patients with OBPF without a perineal open wound were compared with those with OBPF-POW. Data collected included patient demographics, injury details, management, and outcomes. A total of 1,635 patients with blunt pelvic fractures were identified, of which 177 (10.8%) had OBPF. OBPF-POW (36/177) significantly increased the use of angioembolization, occurrence of sepsis, pelvic sepsis, ARDS, and multi-organ system failure. Patients with OBPF-POW had an increase of 13 days in length of hospitalization compared with the OBPF group (P < 0.001), with cost of $120,647.30 and $62,952.72 respectively (P < 0.001). Perineal open wounds complicate open-book pelvic fractures with significant increase in hospital resource utilization. Aggressive multidisciplinary evaluation and management is appropriate to detect and prevent complications.

To present our experience with four urethral injuries in females accompanying a pelvic fracture, managed with primary repair or realignment of the urethra. There were three teenage girls and one adult (22 years old). All the patients had complete urethral injuries associated with a pelvic fracture from accidents. They were managed by immediate suprapubic cystostomy followed by repair or realignment of the urethra over a catheter on the same day. The catheter was removed after 3 weeks and a voiding cysto-urethrogram taken. Thereafter they were followed with regular urethral calibration. All patients voided satisfactorily with a good stream; three were fully continent and the fourth had transient stress urinary incontinence. One patient needed dilatation at 2 months and another visual internal urethrotomy at 5 months. At a mean (range) follow-up of 33 (9-60) months all the patients had a normal voiding pattern and were continent; none developed vaginal stenosis. Primary repair of the urethra, and if that is impossible, simple urethral realignment over a catheter, is the procedure of choice for managing female urethral injury associated with a pelvic fracture. The procedure has the additional advantage of reducing the risk of vaginal stenosis.

Severe pelvic trauma remains associated with elevated mortality, largely due to hemorrhagic shock. The main study objective was to test for correlation between fracture type and mortality. The secondary objective was to assess the efficacy in terms of mortality of multidisciplinary management following a decision-tree in multiple trauma victims admitted to a level 1 trauma center. Between July 2011 and July 2013, 534 severe trauma patients were included in a single-center continuous prospective observational study. All patients with hemorrhagic shock received early treatment by pelvic binder. Patients with active bleeding on full-body CT or persisting hemorrhagic shock underwent arteriography with or without embolization. Pelvic trauma was graded on the Tile classification. The principle end-point was mortality. Median age was 40 years (range, 26-48 years), with a 79% male/female sex ratio. Thirty-two of the 67 patients with pelvic trauma (48%) were in hemorrhagic shock at admission. Median injury severity score (ISS) was 36 (range, 24-43). On the Tile classification, 22 patients (33%) were grade A, 33 (49%) grade B and 12 (18%) grade C. Overall mortality was 19%, and 42% in case of hemorrhagic shock. Mortality was significantly higher with Tile C than A or B (58% vs. 9.1% and 12.1%, respectively; P=0.001). Vertical shear fracture (Tile C) was associated with greater mortality from hemorrhagic shock. IV, case series. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Objectives Osteosynthesis of anterior pubic ramus fractures using one large-diameter screw can be challenging in terms of both surgical procedure and fixation stability. Small-fragment screws have the advantage of following the pelvic cortex and being more flexible. The aim of the present study was to biomechanically compare retrograde intramedullary fixation of the superior pubic ramus using either one large- or two small-diameter screws. Materials and Methods A total of 12 human cadaveric hemipelvises were analysed in a matched pair study design. Bone mineral density of the specimens was 68 mgHA/cm3 (standard deviation (sd) 52). The anterior pelvic ring fracture was fixed with either one 7.3 mm cannulated screw (Group 1) or two 3.5 mm pelvic cortex screws (Group 2). Progressively increasing cyclic axial loading was applied through the acetabulum. Relative movements in terms of interfragmentary displacement and gap angle at the fracture site were evaluated by means of optical movement tracking. The Wilcoxon signed-rank test was applied to identify significant differences between the groups Results Initial axial construct stiffness was not significantly different between the groups (p = 0.463). Interfragmentary displacement and gap angle at the fracture site were also not statistically significantly different between the groups throughout the evaluated cycles (p ⩾ 0.249). Similarly, cycles to failure were not statistically different between Group 1 (8438, sd 6968) and Group 2 (10 213, sd 10 334), p = 0.379. Failure mode in both groups was characterised by screw cutting through the cancellous bone. Conclusion From a biomechanical point of view, pubic ramus stabilisation with either one large or two small fragment screw osteosynthesis is comparable in osteoporotic bone. However, the two-screw fixation technique is less demanding as the smaller screws deflect at the cortical margins. Cite this article: Y. P. Acklin, I. Zderic, S. Grechenig, R. G. Richards, P

Transarterial embolization (AE) can be a lifesaving procedure for severe hemorrhage associated with pelvic fractures. The purpose of this study was to identify demographic and radiographic findings that predict the need for embolization. We performed a retrospective review of all patients with at least one pelvic fracture and admission to the intensive care unit over a 35-month period. Computed tomography (CT) and pelvic radiographs were reviewed. Patient demographics, outcomes, time to angiography, and whether or not embolization was performed were determined. Statistical analysis was used to determine factors associated with the need for AE. Of the 327 total patients with pelvic fractures, 317 underwent CT scanning. Forty-four patients (13.5%) underwent angiography and 25 (7.6%) required therapeutic embolization. There were 39 total deaths (11.6%) with five deaths related to pelvic hemorrhage (1.5%). Multivariate analysis revealed that age older than 55 years (odds ratio [OR], 1.06; P < 0.001), systolic blood pressure less than 90 mmHg in the emergency department (OR, 11.64; P = 0.0008), and CT extravasation (OR, 147.152; P < 0.0001) were significantly associated with the need for embolization. Contrast extravasation was not present in 25 per cent of patients requiring therapeutic AE. The presence of contrast extravasation is highly associated with the need for pelvic embolization in patients with pelvic fractures, but its absence does not exclude the need for pelvic angiography.

Medicare currently reimburses hospitals for inpatient admissions with "bundled" payments based on patient Diagnosis-related Groups (DRGs) regardless of true hospital costs. At present, DRG 536 (fractures of the hip and pelvis) includes a broad spectrum of patients with orthopaedic trauma, likely with varying inpatient resource utilization. With the growing incidence of fractures in the elderly, inadequate reimbursements from Medicare for certain patients with DRG 536 may lead to growing financial strain on healthcare institutions caring for these patients with higher costs. The purposes of the study were to determine whether (1) inpatient length of stay; (2) intensive care unit stay; and (3) ventilator time differ among subpopulations with Medicare DRG 536. A total of 56,683 patients, 65 years or older, with fractures of the hip or pelvis were identified in the 2011 and 2012 National Trauma Data Bank. This clinical registry contains data on trauma cases from more than 900 participating trauma centers, allowing analysis of resource utilization in centers across the United States. Patients were grouped in the following subgroups: hip fractures (n = 35,119), nonoperative pelvic fractures (n = 15,506), acetabulum fractures, operative and nonoperative, (n = 7670), and operative pelvic fractures (n = 682). Total inpatient length of stay, intensive care unit (ICU) stay, and ventilator time were compared across groups using multivariate analysis that controlled for hospital factors. After controlling for patient and hospital factors, difference in inpatient length of stay was -0.2 days for patients with nonoperative pelvis fractures compared with inpatient length of stay for patients with hip fractures (95% CI, -0.4 to -0.1 days; p = 0.001); 1.7 days for patient with acetabulum fractures (95% CI, 1.4-1.9 days; p < 0.001); and 7.7 days for patients with operative pelvic fractures (95% CI, 7.0-8.4 days; p < 0.001).

To review systematically the literature on female urethral injuries associated with pelvic fracture and to determine the optimum management of this rare injury. Using Meta-analysis of Observational Studies in Epidemiology criteria, we searched the Cochrane, Pubmed and OVID databases for all articles available before 30 June 2016 using the terms 'female pelvic fracture urethroplasty', 'female urethral distraction', 'female pelvic fracture urethral injury' and 'female pelvic fracture urethra girls.' Two authors of this paper independently reviewed the titles, abstracts, and articles in duplicate. We identified 162 individual articles from the databases. Fifty-one articles met our criteria for full review, including 158 female patients with urethral trauma. Of these injuries, 83 (53%) were managed with immediate repair; 17/83 (20%) via primary alignment and 66/83 (80%) via anastomotic repair. The remaining 75/158 (47%) were managed with delayed repair. Rates of urethral stenosis and fistula were highest after primary alignment. Urethral integrity appears to be similar after both primary anastomosis and delayed repair; however, patients experienced significantly more incontinence and vaginal stenosis after delayed repair. Patients who underwent delayed urethral repair were more likely to undergo more extensive reconstructive surgery than those who underwent primary repair. The optimum management of female urethral distraction defects is based on very-low-quality literature. Based on our review of the available literature, primary anastomotic repair of a female urethral distraction defect via a vaginal approach as soon as the patient is haemodynamically stable appears to be optimal. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Determine if laparotomy further destabilizes an unstable pelvic injury and increases pelvic volume, and if reduction and stabilization restores pelvic volume and prevents volume changes secondary to laparotomy. Cadaveric pelvic fracture model. Unilateral open-book pelvic ring injuries were created in five fresh cadaveric specimens by directly disrupting the pubic symphysis, left sacroliac joint, and sacrospinous and sacrotuberous ligaments. Pelvic volume was determined using computerized axial tomography for the intact pelvis, disrupted pelvis with both a laparotomy incision opened and closed, and disrupted pelvis stabilized and reduced using an external fixator with the laparotomy incision opened. The average volume increase in the entire pelvis (from the top of the iliac crests to the bottom of the ischial tuberosities) between a nonstabilized injury with the abdomen closed and then subsequently opened was 15 +/- 5% (423 cc). The average increase in entire pelvic volume between a stabilized and reduced pelvis and nonstabilized pelvis, both with the abdomen open, was 26 +/- 5% (692 cc). The public diastasis increased from 3.9 to 9.3 cm in a nonstabilized pelvis with the abdomen closed and then subsequently opened. Application of a single-pin anterior-frame external fixator reduced the pubic diastasis anatomically and reduced the average entire and true (from the pelvic brim to the ischeal tuberosities) pelvic volumes to within 3 +/- 4 and 8 +/- 6% of the initial volume, respectively. We believe that the abdominal wall provides stability to an unstable pelvic ring injury via a tension band effect on the iliac wings. Our results demonstrate that a laparotomy further destabilized an open-book pelvic injury and subsequently increased pelvic volume and pubic diastasis. This could potentially increase blood loss from the pelvic injury and delay the tamponade effect of reduction and stabilization. A single-pin external fixator prevents the destabilizing effect of the

To discuss the clinical effects of damage control resuscitation (DCR) in treating severe multiple trauma in the pelvic fractures. From March 2009 to September 2013, a restrospective analysis was conducted on the clinical data of 28 patients with multiple trauma in the pelvic fractures, including 19 males and 9 females, ranging in age from 21 to 51 years old with an average of 32.5 years old. According to Tile classification of pelvic fractures, 16 cases were type B and 12 cases were type C. Injury severity score (ISS) averaged 32.0±3.4. All cases were treated with damage contral orthopaedics and DCR strategy, namely that used immediately with small capacity of balanced salt solution on admission so as to maintain the blood pressure between 80 to 90 mmHg. At the same time, emergency phase I simple debridement plus external fixator or bundled with fixed pelvic was done, and the chest or abdomen combined injury was treated at first. And limbs fracture was temporary dealing with bone traction or plaster external fixation, etc. After bleeding was controlled by operation, fluid resuscitation was done as fast as possible and the plasma was transfused early according to the proportion of plasma and red cell suspension (2 U:1 U-3 U:2 U). Dosage of balanced salt solution and blood before remedy shock was recorded, and the removal of time of lactic acid and coagulation were observed. Five cases were died after 4 to 15 hours into hospital (3 cases died for severe trauma-hemorrhagic shock and 2 cases for acute respiratory distress syndrome). Twenty-three cases were remedy shock at 1.6 to 4.3 hours after injury with an average of 2.4 hours. Period I operation duration was (78.2±10.3) minutes. Dosage of balanced salt solution was (3,798±340) ml and red cell suspension was 14 to 18 U, fresh frozen plasma (FFP) was (1,267±58) ml (1U FFP=100 ml), blood platelet was 8 to 12 U for 9 patients. The removal time of lactic acid and PT-APTT was (11.4±2.1) hours and (4.3±0.8) hours

To predict the outcome of redo-urethroplasty after failed single or multiple open urethral procedures for pelvic fracture urethral distraction defects. From January 1997 to December 2006, 43 patients underwent redo-urethroplasty for pelvic fracture urethral distraction defect. Forty-one were referred from other centers. All had undergone open surgery along with an endoscopic procedure (one or more procedures in each patient) which included endoscopic internal urethrotomy, urethral stenting or urethral dilations. There were 43 men with mean age of 29 (range 11-52). Eleven had associated injuries: intraperitoneal bladder rupture (3), bladder neck (2), rectum (3), anal sphincter (2), combined bladder, rectum and anal sphincter (1). Trocar suprapubic cystostomy was performed in 22, rail-road procedures in 10 and open suprapubic cystostomy in 11 along with the management of associated injuries as immediate treatment. Of 43 patients, 28 had progressive perineal, and 12 had transpubic repair. Three patients had total bulbar necrosis, and they underwent prepuceal tube reconstruction (1) and staged substitution with BMG and standard scrotal inlay (2). Analysis of various factors like number of attempts at previous surgery and stricture length did not affect the outcome. A successful result was achieved in 36 (83.72%), improved and stable in five and failure in two. The overall result of redo-urethroplasty for pelvic fracture urethral distraction defect continues to be gratifying. Failures happen usually within the first 3 months. Substitution urethroplasty can be reserved for those who have long distraction defect. Long-term follow-up is essential using stringent criteria to measure success.

To test the hypothesis that a new surgical technique using elaborated perineal anastomotic urethroplasty combined with laparoscopic omentoplasty for patients with complex and prior failed pelvic fracture urethral defect repair was feasible, safe, and effective. We performed a prospective, observational, stage 2a study to observe treatment outcomes of combined perineal and laparoscopic approach for urethroplasty in patients with pelvic fracture urethral defect at a single center in Pune, India, between January 2012 and February 2013. Complex and redo patients with pelvic fracture urethral defect occurring after pelvic fracture urethral injury were included in the study. Anterior urethral strictures were excluded. The primary study outcome was the success rate of the surgical technique, and the secondary outcome was to evaluate feasibility and safety of the procedure. The clinical outcome was considered a failure when any postoperative instrumentation was needed. Fifteen male patients with a median age of 19 years were included in the study. Seven patients were adolescents (12-18 years) and 8 patients (53.3%) were adults (19-49 years). The mean number of prior urethroplasties was 1.8 (range, 1-3). All patients underwent elaborated bulbomembranous anastomosis using a perineal approach with inferior pubectomy combined with laparoscopic mobilization of the omentum into the perineum to envelope the anastomosis and to fill the perineal dead space. Of 15 patients, 14 (93.3%) were successful and 1 (6.6%) failed. One adolescent boy 14 years old developed a recurrent stricture 2 months after the procedure and was managed using internal urethrotomy. Median follow-up was 18 months (range, 13-24 months). Combining a laparoscopic omentoplasty to a membranobulbar anastomosis for complex and redo pelvic fracture urethral injury is successful, feasible, safe, and with minimal additional morbidity to the patient. The technique has the advantage of a perineal incision and the ability

Pelvic fracture urethral injury (PFUI) management in male adults and children is controversial. The jury is still out on the best way to manage these injuries in the short and long-term to minimise complications and optimise outcomes. There is also little in the urological literature about pelvic fractures themselves, their causes, grading systems, associated injuries and the mechanism of PFUI. A review of pelvic fracture and male PFUI literature since 1757 was performed to determine pelvic fracture classification, associated injuries and, PFUI classification and management. The outcomes of; suprapubic catheter (SPC) insertion alone, primary open surgical repair (POSR), delayed primary open surgical repair (DPOSR), primary open realignment (POR), primary endoscopic realignment (PER), delayed endoscopic treatment (DET) and delayed urethroplasty (DU) in male adults and children in all major series have been reviewed and collated for rates of restricture (RS), erectile dysfunction (ED) and urinary incontinence (UI). For SPC, POSR, DPOSR, POR, PER, DET and DU; (I) mean RS rate was 97.9%, 53.9%, 18%, 58.3%, 62.0%, 80.2%, 14.4%; (II) mean ED rate was 25.6%, 22.5%, 71%, 37.2%, 23.6%, 31.9%, 12.7%; (III) mean UI rate was 6.7%, 13.6%, 0%, 14.5%, 4.1%, 4.1%, 6.8%; (IV) mean FU in months was 46.3, 29.4, 12, 61, 31.4, 31.8, 54.9. For males with PFUI restricture and new onset ED is lowest following DU whilst UI is lowest following DPOSR. On balance DU offers the best overall outcomes and should be the treatment of choice for PFUI.

2009-01-01

The objective of the present study was to evaluate the results and the complications of delayed retropubic urethroplasty of completely transected urethra associated with pelvic fracture in girls. From 2002 to 2008, a total of 7 girls with complete urethral disruption after pelvic fracture were referred to our center and all of them underwent delayed retropubic urethroplasty with end-to-end anastomosis of the urethra. Seven female patients with a median age of 6 years old underwent delayed end-to-end anastomosis. The median time to surgery was 6 months from the trauma. Voiding was normal after catheter removal in all of the patients. The median follow-up was 36 months. Three patients had mild stress urinary incontinence after catheter removal. There are some different strategies for management of complete urethral avulsion in females who have sustained pelvic fracture, including early realignment, bladder flaps, and end-to-end anastomosis. The strategy of delayed end-to-end anastomosis urethroplasty with retropubic approach is sound and produces acceptable results. The use of flexible cystoscope and omental flap is effective in achieving continence after urethroplasty in such cases.

Objective To determine whether the evolution of the authors’ clinical pathway for the treatment of hemodynamically compromised patients with pelvic fractures was associated with improved patient outcome. Summary Background Data Hemodynamically compromised patients with pelvic fractures present a complex challenge. The multidisciplinary trauma team must control hemorrhage, restore hemodynamics, and rapidly identify and treat associated life-threatening injuries. The authors developed a clinical pathway consisting of five primary elements: immediate trauma attending surgeon’s presence in the emergency department, early simultaneous transfusion of blood and coagulation factors, prompt diagnosis and management of associated life-threatening injuries, stabilization of the pelvic girdle, and timely insinuation of pelvic angiography and embolization. The addition of two orthopedic pelvic fracture specialists led to a revision of the pathway, emphasizing immediate emergency department presence of the orthopedic trauma attending to provide joint decision making with the trauma surgeon, closing the pelvic volume in the emergency department, and using alternatives to traditional external fixation devices. Methods Using trauma registry and blood bank records, the authors identified pelvic fracture patients receiving blood transfusions in the emergency department. They analyzed patients treated before versus after the May 1998 revision of the clinical pathway. Results A higher proportion of patients in the late period had blood pressure less than 90 mmHg (52% vs. 35%). In the late period, diagnostic peritoneal lavage was phased out in favor of torso ultrasound as a primary triage tool, and pelvic binding and C-clamp application largely replaced traditional external fixation devices. The overall death rate decreased from 31% in the early period to 15% in the later period, as did the rate of deaths from exsanguination (9% to 1%), multiple organ failure (12% to 1%), and death

BACKGROUND Lower limb and pelvic injuries and fractures occur at a very high incidence in motor vehicle accidents. In this study, the characteristics (e.g., body side, bone location, and fracture severity) of lower limb and pelvic fractures that occurred during front-impact collisions were correlated with the injured patients' sex, age, and position in the vehicle. MATERIAL AND METHODS We retrospectively evaluated 191 patients (136 males, 55 females) who were injured in motor vehicle accidents, specifically in frontal collisions. RESULTS This study revealed that most of lower limb and pelvic fractures occurred in males (71.2%; p=.000), 19-36 years old (55.5%; p=.000), small vehicles (86.4%; p=.000), and rear seat passengers (49.2%; p=.000). Fractures most commonly occurred in the left side of the body (46.6%; p=.000) and upper legs (37.7%; p=.000). Severity scores were higher (2.76) in males than females (2.07). No statistically significant was found in severity scores of patients and other personal characteristics and fracture features of patients with lower limb and pelvic fractures who were injured in a vehicle during front-impact collisions (p>0.05). CONCLUSIONS The results of this study will be useful for the automobile industry, forensics and criminal scientists, and for trauma research studies.

Although there were many different types of fixation techniques for sacroiliac dislocation fracture, the treat remained challenging in posterior pelvic ring injury. The purpose of this study was to evaluate the biomechanical effects of a novel fixation system we designed. 12 human cadavers (L3-pelvic-femora) were used to compare biomechanical stability after reconstruction on the same specimens in four conditions: (1) intact, (2) cable system, (3) plate-pedicle screw system, and (4) cable system and plate-pedicle screw combination system (combination system). Biomechanical testing was performed on a material testing machine for evaluating the stiffness of the pelvic fixation construct in compression and torsion. The cable system and plate-pedicle screw system alone may be insufficient to resist vertical shearing and rotational loads; however the combination system for unstable sacroiliac dislocation fractures provided significantly greater stability than single plate-pedicle or cable fixation system. The novel fixation system for unstable sacroiliac dislocation fractures produced sufficient stability in axial compression and axial rotation test in type C pelvic ring injuries. It may also offer a better solution for sacroiliac dislocation fractures. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pelvic radiotherapy is a treatment delivered to an estimated 150,000 to 300,000 people annually across high-income countries. Fractures due to normal stresses on weakened bone due to radiotherapy are termed insufficiency fractures. Pelvic radiotherapy-related interruption of the blood supply to the hip is termed avascular necrosis and is another recognised complication. The reported incidences of insufficiency fractures are 2.7% to 89% and risk of developing avascular necrosis is 0.5%. These complications lead to significant morbidity in terms of pain, immobility and consequently risk of infections, pressure sores and mortality. To assess the effects of pharmacological interventions for preventing insufficiency fractures and avascular necrosis in adults over 18 years of age undergoing pelvic radiotherapy. We performed electronic literature searches in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and DARE to 19 April 2017. We also searched trial registries. Further relevant studies were identified through handsearching of citation lists of included studies. Randomised controlled trials (RCTs) or non RCTs with concurrent comparison groups including quasi-RCTs, cluster RCTs, prospective cohort studies and case series of 30 or more participants were screened. We included studies assessing the effect of pharmacological interventions in adults over 18 years of age undergoing radical pelvic radiotherapy as part of anticancer treatment for a primary pelvic malignancy. We excluded studies involving radiotherapy for bone metastases. We assessed use of pharmacological interventions at any stage before or during pelvic radiotherapy. Interventions included calcium or vitamin D (or both) supplementation, bisphosphonates, selective oestrogen receptor modulators, hormone replacement therapy (oestrogen or testosterone), denosumab and calcitonin. Two review authors independently assessed trial quality and extracted data. We contacted study authors to

Background Computed tomography (CT) is superior to conventional radiography (CR) for assessing internal fixation of pelvic fractures, but with a higher radiation exposure. Low-dose CT (LDCT) could possibly have a sufficient diagnostic accuracy but with a lower radiation dose. Purpose To compare postoperative diagnostic accuracy of LDCT and CR after open reduction and internal fixation of pelvic fracture. Material and Methods Twenty-one patients were examined with LDCT and CR 0-9 days after surgery. The examinations were reviewed by two musculoskeletal radiologists. Hardware, degree of fracture reduction, image quality, and reviewing time were assessed, and effective radiation dose was calculated. Inter-reader agreement was calculated. Results LDCT was significantly better than CR in determining whether hardware positioning was assessable ( P < 0.001). Acetabular congruence was assessable in all fractured patients with LDCT. In 12 of the 32 assessments with CR of patients with an acetabular fracture, joint congruence was not assessable due to overlapping hardware ( P = 0.001). Image quality was significantly higher for LDCT. Median time to review was 240 s for LDCT compared to 180 s for CR. Effective dose was 0.79 mSv for LDCT compared to 0.32 mSv for CR ( P < 0.001). Conclusion LDCT is more reliable than CR in assessing hardware position and fracture reduction. Joint congruency is sometimes not possible to assess with CR, due to overlapping hardware. The image quality is higher, but also the effective dose, with LDCT than with CR.

Open fractures of the pelvis remain a devastating injury with a high mortality and morbidity. Such injuries require an aggressive treatment plan and the coordination of trauma and orthopaedic surgeons to achieve the best outcomes. We report our experience at the University of Tennessee Medical Center at Knoxville with open pelvic fractures over the last ten years. After IRB and institutional approval, we reviewed patients admitted with a diagnosis of open fracture of the pelvis from 1999 to 2009. Demographic and admission data were recorded in the trauma registry (TRACS) of the Level I Trauma Center, serving the 1.2 million people living in the regions of east Tennessee, western North Carolina and southeastern Kentucky. Data on fractures were obtained from review of the medical records and radiographs within the chart. There were 3053 pelvic fractures from January 1999 to December 2009. There were 231 deaths in this group (6%) and ages ranged from 18 to 89 years old and Injury Severity Scores ranged from 4 to 75, with a mean of 18.3. Seventy five percent of patients were able to be discharged home. Fifty-two fractures were open. There were 43 men and the mean age was 39 years old. Average ISS was 23 and ranged from 5 to 50. There were 10 deaths (19%) and eight patients underwent angioembolization for control of bleeding (3 deaths). Motorcycle crashes were the most frequent cause of an open fracture, with lateral compression injuries representing 71%. A defined algorithm for fracture management has been in place and employed to assure adequate resuscitation and fracture care and is presented. Open pelvic fractures are usually the result of a high energy transfer, and convey a high morbidity and mortality. A defined resuscitation and fixation strategy improves outcome from historical reports. Injuries from penetrating mechanisms are associated with less morbidity and lower mortality.

The purpose of our study was (1) to determine whether four-view radiography of the pelvis is as reliable and accurate as computed tomography (CT) in diagnosing sacral and pelvic fractures, in addition to coxofemoral and sacroiliac joint subluxation or luxation, and (2) to evaluate the effect of the amount of training in reading diagnostic imaging studies on the accuracy of diagnosing sacral and pelvic fractures in dogs. Sacral and pelvic fractures were created in 11 canine cadavers using a lateral impactor. In all cadavers, frog-legged ventro-dorsal, lateral, right and left ventro-45°-medial to dorsolateral oblique frog leg ("rollover 45-degree view") radiographs and a CT of the pelvis were obtained. Two radiologists, two surgeons and two veterinary students classified fractures using a confidence scale and noted the duration of evaluation for each imaging modality and case. The imaging results were compared to gross dissection. All evaluators required significantly more time to analyse CT images compared to radiographic images. Sacral and pelvic fractures, specifically those of the sacral body, ischiatic table, and the pubic bone, were more accurately diagnosed using CT compared to radiography. Fractures of the acetabulum and iliac body were diagnosed with similar accuracy (at least 86%) using either modality. Computed tomography is a better method for detecting canine sacral and some pelvic fractures compared to radiography. Computed tomography provided an accuracy of close to 100% in persons trained in evaluating CT images.

Summary Background and objectives The microvascular circulation plays an important role in bone health. This study examines whether albuminuria, a marker of renal microvascular disease, is associated with incident hip and pelvic fractures. Design, setting, participants, & measurements This study reanalyzed data from the Ongoing Telmisartan Alone and in combination with Ramipril Global End Point Trial/Telmisartan Randomized Assessment Study in Angiotensin-Converting Enzyme Intolerant Subjects with Cardiovascular Disease trials, which examined the impact of renin angiotensin system blockade on cardiovascular outcomes (n=28,601). Albuminuria was defined as an albumin-to-creatinine ratio≥30 mg/g (n=4597). Cox proportional hazards models were used to determine the association of albuminuria with fracture risk adjusted for known risk factors for fractures, estimated GFR, and rapid decline in estimated GFR (≥5%/yr). Results There were 276 hip and pelvic fractures during a mean of 4.6 years of follow-up. Participants with baseline albuminuria had a significantly increased risk of fracture compared with participants without albuminuria (unadjusted hazard ratio=1.62 [1.22, 2.15], P<0.001; adjusted hazard ratio=1.36 [1.01, 1.84], P=0.05). A dose-dependent relationship was observed, with macroalbuminuria having a large fracture risk (unadjusted hazard ratio=2.01 [1.21, 3.35], P=0.007; adjusted hazard ratio=1.71 [1.007, 2.91], P=0.05) and microalbuminuria associating with borderline or no statistical significance (unadjusted hazard ratio=1.52 [1.10, 2.09], P=0.01; adjusted hazard ratio=1.28 [0.92, 1.78], P=0.15). Estimated GFR was not a predictor of fracture in any model, but rapid loss of estimated GFR over the first 2 years of follow-up predicted subsequent fracture (adjusted hazard ratio=1.47 [1.05, 2.04], P=0.02). Conclusions Albuminuria, especially macroalbuminuria, and rapid decline of estimated GFR predict hip and pelvic fractures. These findings support a

Pelvic ring stability is maintained passively by both the osseous and the ligamentous apparatus. Therapeutic approaches focus mainly on fracture patterns, so ligaments are often neglected. When they rupture along with the bone after pelvic ring fractures, disrupting stability, ligaments need to be considered during reconstruction and rehabilitation. Our aim was to determine the influence of ligaments on open-book injury using two experimental models with body donors. Mechanisms of bone avulsion related to open-book injury were investigated. Open-book injuries were induced in human pelves and subsequently investigated by anatomical dissection and endoscopy. The findings were compared to CT and MRI scans of open-book injuries. Relevant structures were further analyzed using plastinated cross-sections of the posterior pelvic ring. A fragment of the distal sacrum was observed, related to open-book injury. Two ligaments were found to be responsible for this avulsion phenomenon: the caudal portion of the anterior sacroiliac ligament and another ligament running along the ventral surface of the third sacral vertebra. The sacral fragment remained attached to the coxal bone by this second ligament after open-book injury. These results were validated using plastination and the structures were identified. Pelvic ligaments are probably involved in sacral avulsion caused by lateral traction. Therefore, ligaments should to be taken into account in diagnosis of open-book injury and subsequent therapy.

Determining whether a Tile-B2 pelvic fracture is stable is very challenging. We sought to identify the role of ultrasonography in determining the stability of Tile-B2 pelvic fractures. We collected the clinical data of patients with Tile-B2 pelvic fractures who presented at Xi'an Hong-Hui Hospital between June 1, 2016, and August 5, 2016. The treatment strategy of each patient was determined by a team of senior surgeons in the department. A single sinologist observed the movement of the fracture sites in patients during rest, under compression, and during separation to determine fracture stability. According to the pelvic fracture stability assessment, an appropriate treatment strategy was redetermined. Overall, 7 patients, including 5 women and 2 men, with Tile-B2 pelvic fractures were included in this case series. During the initial examination, senior surgeons recommended that 2 patients should undergo internal fixation and 4 patients, conservative treatment; treatment was undecided for 1 patient. After ultrasonography examination, 4 patients underwent surgery via the Stoppa (n = 2) or ilioinguinal approach (n = 1) or cannulated screw fixation (n = 1). The rest of the patients (n = 3) received conventional treatment. Follow-up ranged from 6 to 10 months. Most of the patients showed excellent functions based on their last Majeed grading scores. There were no complications during the follow-up. Using ultrasonography examination, the preoperative treatment plan in 1 patient was changed, and the uncertain preoperative plan in 1 patient was identified. Preoperative assessment of stability using ultrasonography may assist surgeons in making appropriate treatment choices for patients with Tile-B2 pelvic fractures.

As a result of pelvic fracture urethral distraction defects, urinary continence relies predominantly on intact bladder neck function. Hence, when cystoscopy and/or cystography reveals an open bladder neck before urethroplasty, the probability of postoperative urinary incontinence may be significant. Unresolved issues are the necessity, the timing and the type of bladder neck repair. We report the outcome of various therapeutic options in patients with pelvic fracture urethral distraction defects and open bladder neck. We also attempt to identify prognostic factors of incontinence before urethroplasty. We retrospectively reviewed the records of 15 patients with a mean age of 30 years in whom an open bladder neck was identified before posterior urethroplasty between January 1981 and October 1997. Of the 15 patients 6 were continent and 8 were incontinent postoperatively. One patient underwent artificial urethral sphincter implantation simultaneously with pelvic fracture urethral distraction defect repair and was dry postoperatively without sphincter activation. Average bladder neck and prostatic urethral opening on the cystourethrogram before urethroplasty was significantly longer in incontinent (1.68 cm.) than in continent (0.9 cm.) patients. Of the 8 patients who were incontinent 6 underwent bladder neck reconstruction, 1 artificial urinary sphincter and 1 periurethral collagen implant. Five patients with bladder neck reconstruction are totally continent and 1 requires 1 pad daily. The patient who underwent collagen implant requires 2 pads daily and the patient who received an artificial urethral sphincter has minor urge leakage. Open bladder neck before urethroplasty may herald postoperative incontinence which may be predicted by radiographic and cystoscopic features. Evaluation of the risk of postoperative incontinence may be valuable, and eventually guide the necessity and timing of anti-incontinence surgery, although our preference remains to manage the pelvic

Delayed or non-union of a sacral fracture is a serious clinical condition that may include chronic pain, sitting discomfort, gait disturbances, neurological problems, and inability to work. It is also a difficult reconstruction problem. Late correction of the deformity is technically more demanding than the primary treatment of acute pelvic injuries. Open reduction, internal fixation (ORIF), excision of scar tissue, and bone grafting often in a multi-step approach are considered to be the treatment of choice in delayed unions of the pelvic ring. This procedure implies the risk of neurological and vascular injuries, infection, repeated failure of union, incomplete correctionmore » of the deformity, and incomplete pain relief as the most important complications. We report a new approach for minimally invasive treatment of a delayed union of the sacrum without vertical displacement. A patient who suffered a Malgaigne fracture (Tile C1.3) was initially treated with closed reduction and percutaneous screw fixation (CRPF) of the posterior pelvic ring under CT navigation and plating of the anterior pelvic ring. Three months after surgery he presented with increasing hip pain caused by a delayed union of the sacral fracture. The lesion was successfully treated percutaneously in a single step procedure using CT navigation for drilling of the delayed union, autologous bone grafting, and screw fixation.« less

Purpose We examined the success of early endoscopic realignment of pelvic fracture associated urethral injury after blunt pelvic trauma. Materials and Methods A retrospective review was performed of patients with pelvic fracture associated urethral injury who underwent early endoscopic realignment using a retrograde or retrograde/antegrade approach from 2004 to 2010 at a Level 1 trauma center. Followup consisted of uroflowmetry, post-void residual and cystoscopic evaluation. Failure of early endoscopic realignment was defined as patients requiring urethral dilation, direct vision internal urethrotomy, posterior urethroplasty or self-catheterization after initial urethral catheter removal. Results A total of 19 consecutive patients (mean age 38 years) with blunt pelvic fracture associated urethral injury underwent early endoscopic realignment. Twelve cases of complete urethral disruption, 4 of incomplete disruption and 3 of indeterminate status were noted. Mean time to realignment was 2 days and mean duration of urethral catheterization after realignment was 53 days. One patient was lost to followup after early endoscopic realignment. Using an intent to treat analysis early endoscopic realignment failed in 15 of 19 patients (78.9%). Mean time to early endoscopic realignment failure after catheter removal was 79 days. The cases of early endoscopic realignment failure were managed with posterior urethroplasty (8), direct vision internal urethrotomy (3) and direct vision internal urethrotomy followed by posterior urethroplasty (3). Mean followup for the 4 patients considered to have undergone successful early endoscopic realignment was 2.1 years. Conclusions Early endoscopic realignment after blunt pelvic fracture associated urethral injury results in high rates of symptomatic urethral stricture requiring further operative treatment. Close followup after initial catheter removal is warranted, as the mean time to failure after early endoscopic realignment was 79 days in

The purpose of this study was to describe a form of anterior wall acetabular fracture, which has been inadequately defined in the literature. Retrospective analysis of consecutive patients. Level 1 trauma center. A retrospective analysis of consecutive acetabulum patients treated by a single surgeon between 1999 and 2005 identified 6 patients with a form of anterior wall fracture without involvement of the pelvic brim. All fractures were treated operatively. Open reduction and internal fixation through an anterior surgical approach. Final radiographic appearance and modified Merle d'Aubigne score. All 6 cases demonstrated characteristics of an atypical fracture of the anterior wall, involving the anterior rim of the acetabulum similar in nature to those described for the posterior wall, rather than the standard anterior wall fracture type described by Letournel. Of the 6 cases that were identified, 5 had follow-up 1 year or greater with a mean modified Merle d'Aubigne Score of 17 (range: 17-18). A form of anterior wall acetabular fracture exists, which involves the anterior acetabular rim without involvement of the pelvic brim. It can occur in young patients with high-energy mechanisms of injury, as well as in the elderly with low-energy trauma. With appropriate surgical management, using a modified Smith-Peterson approach, good to excellent clinical outcomes should be expected.

Common complications of pelvic fractures include visceral injury, large-volume hemorrhage, genitourinary injury, rectal injury, and pulmonary embolism. On the other hand, traumatic hernia is a rare complication, especially in association with pelvic fractures. We report a case of bowel perforation due to traumatic hernia at a pelvic fracture site. A 65-year-old female was presented at our hospital for further examination and treatment of ileus. She was diagnosed with bowel perforation due to traumatic hernia at a pelvic fracture site, and an emergency operation was thus immediately performed. We performed segmental jejunum resection and constructed jejunostomy, and the iliac bone fracture was fixed with four pins. In the postoperative course, she received antibiotics and vasopressors for septic shock. However, there was no need for either a ventilator, dialysis or admission to the ICU. At seven days after the operation, a residual abscess was detected in the pouch of Douglas. We performed percutaneous drainage (Clavien-Dindo IIIa) and jejunostomy closedown 35 days after the first operation. The postoperative course was without complication, but she received rehabilitation until she was able to walk unaided. She was discharged 64 days after the first operation. The occurrence of traumatic hernia is rare, especially in association with pelvic fractures. Although its rarity, traumatic hernia follows a severe course. Thus, proper diagnosis and effective treatment are necessary. Surgeons treating patients with pelvic injuries should consider the possibility of any complications and perform a work-up examination in order to achieve an accurate diagnosis at an earlier time point.

Unstable pelvic ring injuries are complex and risky injuries due to high morbidity and mortality. Although anterior pelvic external fixator is a suitable method for rapid stabilization of an injured pelvic ring, due to some disadvantages such as high complication rate, nerve damage, and difficulties of patient's mobility and comfort, there has recently been increased searching for alternative methods for stabilization of the pelvic ring. Pubic symphysis zone freely moves in pelvic models. This study aims to evaluate the biomechanical stability of anterior pelvic bridge plating and compare it with supraacetabular external fixators in an untreated unstable pelvic fracture model. Samples were loaded statically with 2-mm/min loading rate in single leg standing position. Maximum load was 2.3 kN. When loading the samples, photographs were taken continuously. Stiffness values were calculated from the load displacement curves. Some reference parameters were described and were measured from unloaded and 2.3-kN-loaded photographs of the test. The mean stiffness values were 491.14 ± 52.22, 478.55 ± 41.44, and 470.25 ± 44.51 N/mm for anterior pelvic bridge plating group, supraacetabular external fixator group, and Control group, respectively. According to the measured parameters from photographs, the mean displacement at the pubic symphysis was 4.7 ± 0.32, 15.8 ± 2.01, and 18.2 ± 0.47 mm for anterior pelvic bridge plating, supraacetabular external fixator, and Control group, respectively. The highest displacement in the pubic symphysis was found in Control group, and minimum displacement was observed in anterior pelvic bridge plating group. When the perpendicular distance between the right and left lower end of ischium was examined, it was observed that displacement was minimum in anterior pelvic bridge plating group compared to other two groups, regarding to the high stability of pubic symphysis. In conclusion, this study revealed

The purpose of this study is to compare INFIX to plating in the treatment of unstable pelvic ring injuries with disruption of the symphysis. Twenty-four patients treated with INFIX were compared to 28 patients fixed by plating. All patients had anterior and posterior fixation. Injuries were classified using the Young and Burgess and AO/OTA classification systems. Reductions of the pelvic ring were assessed using the pelvic deformity index (PDI) and symphyseal widening. Patients were contacted to get functional outcomes using the Majeed scoring system and complications were tabulated . INFIX was inferior to plating at reducing symphyseal widening (INFIX 10.72± 5.0 Plates 6.97 ± 3.39 P = 0.012) but similar in reducing the pelvic deformity index. (INFIX 0.0221± .015 Plates 0.0190 ± .0105 P = 0 .38). Majeed scores were similar 83.95 ± 15.2 (median 89, range 51-100) for INFIX and 77.67± 16.7 (median 79, range 54-100) for plating. Complications included infection (1 (4%) INFIX , 4 (14%) plates), improper hardware placement or failure (2 (8%) INFIX, 3 (11%) plates), and heterotopic ossification (11 (46%) INFIX, 16 (57.1%) plates). Infection in the plated patients was related to urological injury in 3/4 cases. Plating provides better reduction of the pubic symphysis and requires only one surgery. Outcomes scores were similar. INFIX may be preferable in obese patients, young women of childbearing age or those with urological injury.

To explore selection and efficacy assessment for membranous urethral trauma caused by pelvic fracture. From June 2000 to August 2010, 72 patients with membranous urethral trauma caused by pelvic fracture were selected. There were 46 males and 26 females,ranging age from 26 to 62 years (averaged 35.2 years). The time from injury to hospitalization time was 1 to 3 hours. According to Tile pelvic fracture classification, there were 8 patients with type A, 45 patients with type B, 19 patients with type C. Thirty of the 35 patients with partial rupture of posterior urethral were treated by catheterization,5 patients treated by rupture anastomosis on the stage I combined with cystostomy; 25 of the 37 patients with complete rupture of posterior urethra were treated by early realignment, and 12 patients were treated by cystostomy. Urinary incontinence, impotence and urethrostenosis were evaluated. All patients were followed up for 5 to 10 years (mean 7.7 years). Incidence of urethrostenosis, impotence and urinary incontinence in patients treated by cystostomy were significantly higher than rupture anastomosis on the stage I and early realignment (P < 0.05); while incidence in patients treated by catheterization was significantly lower than other groups (P < 0.05). For patients with partial rupture of posterior urethral, catheterization and rupture anastomosis on the stage I are preferred methods; while patients with complete rupture of posterior urethra, early realignment is a preferred method with advantages of simple operation and less complications.

To present our institutional experience in the management of pelvic fracture urethral distraction defects with urethral pull-through operation. Seventy-six patients (average age 34.5 years) with posterior urethral strictures caused by pelvic fracture urethral distraction defects underwent urethral pull-through operation at our department from July 1995 to September 2009. The estimated urethral stricture length was 2.0-3.5 cm (mean 2.5). Of these patients, 31 (41%) had undergone failed urethroplasty or urethrotomy after the initial management, and 5 (7%) had urethrorectal fistula. Urethral pull-through operation was performed 4-7 months (mean 4.9) after initial treatment or failed urethral reconstruction. The clinical outcome was considered a failure when any postoperative intervention was needed. Follow-up was 14-74 months (mean 42.5). The overall success rate was 89% (68/76). All treatment failures occurred within the first 6 months postoperatively. Failed repairs were successfully managed with internal urethrotomy in 1 patient, by urethral dilation in 6, and by another urethroplasty in 1. All patients were urinary-continent postoperatively. Of the potent patients, 2 (5%) became impotent after urethroplasty. There was no chordee, penile shortening, or urethral fistula recurrence. Urethral pull-through operation might be a less demanding and less time-consuming procedure. It does not increase the rate of impotence or incontinence and, with a high success rate, might serve as an alternative method for the management of pelvic fracture urethral distraction defects.

The focused abdominal sonography for trauma (FAST) examination has been reported to be unreliable in pelvic fracture patients. Additionally, given the advent of new therapeutic interventions, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), rapid identification of intra-abdominal hemorrhage compared with Zone III hemorrhage may guide different therapeutic strategies. We hypothesized that FAST is reliable for detecting clinically significant intra-abdominal hemorrhage in the face of complex pelvic fractures. Our pelvic fracture database of all hemodynamically unstable patients requiring intervention from January 1, 2005, to July 1, 2015, was reviewed. The FAST examination was compared with operative and computed tomography (CT) scan findings. Confirmatory evaluation for FAST(-) patients was considered positive if therapeutic intervention was required. During the study period, 81 patients in refractory shock with FAST imaging in our emergency department (ED) underwent pelvic packing. Mean age was 45 ± 2 years and Injury Severity Score was 50 ± 1.5. The FAST examination was negative in 53 patients; 52 patients did not require operative intervention for abdominal bleeding while one patient required splenectomy. The FAST examination was positive in 28 patients; 26 had findings confirmed by CT or laparotomy while two patients did not have intra-abdominal hemorrhage on further evaluation. The sensitivity and specificity for FAST in this population was 96% and 96%, respectively, positive predictive value was 93%, and negative predictive value was 98%. The false-negative and -positive rates for FAST were 2% and 7%. Focused abdominal sonography for trauma examination reliably identifies clinically significant hemoperitoneum in life-threatening, pelvic fracture related hemorrhage. The incidence of a false-negative FAST in this unstable pelvic fracture population was 2%. FAST results may be used when determining the role of REBOA in these

Erectile dysfunction (ED) is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5) questionnaire. Nocturnal penile tumescence (NPT) testing confirmed the occurrence of ED in 96 (80%) patients on whom penile duplex ultrasound and neurophysiological testing were further performed. Of these ED patients 29 (30%) were demonstrated only with vascular abnormality, 41 (42.7%) were detected only with neural abnormality, 26 (27.1%) revealed mixed abnormalities. Of the 55 patients (29+26) with vascular problems, 7 patients (12.7%) with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine), 31 (56.4%) with corporal veno-occlusive dysfunction and 17 (30.9%) had both problems. Of the 67 (41+26) patients with abnormal neurophysiological outcomes, 51 (76.1%) with abnormal bulbocavernosus re?ex (BCR), 20 (29.9%) with pathological pudendal nerve evoked potentials (PDEPs) and 25 (37.3%) with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs). Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED.

Of the 55 patients (29+26) with vascular problems, 7 patients (12.7%) with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine), 31 (56.4%) with corporal veno-occlusive dysfunction and 17 (30.9%) had both problems. Of the 67 (41+26) patients with abnormal neurophysiological outcomes, 51 (76.1%) with abnormal bulbocavernosus reflex (BCR), 20 (29.9%) with pathological pudendal nerve evoked potentials (PDEPs) and 25 (37.3%) with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs). Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED. PMID:26689522

Perform a systematic review for the most relevant pelvic injury research involving PMHS. The review begins with an explanation of the pelvic anatomy and a general description of pelvic fracture patterns followed by the particular case of pelvic fractures sustained in pedestrian-vehicle collisions. Field data documenting the vehicle, crash, and human risk factors for pedestrian pelvic injuries are assessed. A summary of full-scale PMHS tests and subsystem lateral pelvic tests is provided with an interpretation of the most significant findings for the most relevant studies. Based on the mechanisms of pedestrian pelvic injury, force, acceleration, and velocity and compression have been assessed as predictive variables by researchers although no consensus criterion exists.

The objective was to assess the predictive performance of different intravascular contrast extravasation (ICE) characteristics for need for pelvic transarterial embolization (TAE) to determine the risk factors of false-positives. A retrospective study was performed in our trauma center between 2010 and 2015. All severe trauma patients with pelvic fracture were included. Pelvic ICE characteristics on computed tomography (CT) scan were studied: arterial (aSICE), portal surface (pSICE), and extension (exSICE) anatomic relationships. The overall predictive performance of ICE surfaces for pelvic TAE was analyzed using receiver operating characteristic curves. The analysis focused on risk factors for false-positives. Among 311 severe trauma patients with pelvic ring fracture (mean age, 42 ± 19 years, mean Injury Severity Score, 27 ± 19), 94 (30%) had at least one pelvic ICE on the initial CT scan. Patients requiring pelvic TAE had significantly larger aSICE and pSICE than others (P=0.001 and P=0.035, respectively). The overall ability of ICE surfaces to predict pelvic TAE was modest (aSICE AUC, 0.76 [95% CI, 0.64-0.90]; P=0.011) or non-significant (pSICE and exSICE). The high-sensitivity threshold was defined as aSICE ≥20 mm. Using this threshold, 76% of patients were false-positives. Risk factors for false-positives were: admission systolic blood pressure ≥90 mmHg (63% versus 20%; P=0.03) and low transfusion needs (63% versus 10%; P=0.009), extravasation in contact with complex bone fracture (78% versus 30%; P=0.008) or the absence of a direct relationship between extravasation and a large retroperitoneal hematoma (100% versus 38%; P<0.001). A significant pelvic ICE during the arterial phase does not guarantee the need for pelvic TAE. Three-quarter of patients with aSICE ≥20 mm did not need pelvic TAE. Several complementary CT scan criteria will help to identify this risk of false-positives to determine adequate hemostatic pelvic procedures.This work is an

To compare the frequency of complications, including screw loosening and pelvic canal narrowing, associated with dynamic compression plating, locking plating, and double locking plating of ilial fractures in cats. Historical cohort study. The radiographs and medical records of cats with pelvic fractures that were presented between 2004 and 2013 were reviewed. The cases were categorized based on the plate type and number as dynamic compression plate (DCP), single locking plate (LPS) and double locking plates (dLPS). The frequency of screw loosening was compared across categories using a Fisher's exact test. The change in pelvic alignment, described by the change in sacral index (postoperative sacral index-followup sacral index), was compared across plate categories using ANOVA. The frequency of screw loosening for DCP (5/10) was significantly higher than LPS (1/13) and dLPS (0/11) (P = .05, P = .012, respectively). There was no significant difference in the SI change across plate categories. The mean change in sacral index for DCP was -0.11 (95%CI -0.25 to 0.03), for LPS was 0.0007 (95%CI -0.07 to 0.08), and for dLPS was -0.01 (95%CI -0.04 to 0.02). None of the cats showed constipation postoperatively. Screw loosening occurred less often but the change in pelvic canal alignment was not significantly different in ilial fractures repaired with LPS or dLPS compared to ilial fractures repaired with DCP. Locking plating of ilial fractures in cats may offer advantages compared to nonlocking plating. © Copyright 2015 by The American College of Veterinary Surgeons.

Are routine pelvic radiographs in major pediatric blunt trauma necessary?

Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children. To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma. We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture. Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P = 0.008, NPV 99, sensitivity 96, 8.98 (1.52-52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS <14, positive urinalysis, abdominal pain/tenderness, femur fracture) and five high-risk mechanisms of injury (unrestrained motor vehicle collision [MVC], MVC with ejection, MVC rollover, auto vs. pedestrian, auto vs. bicycle). Pelvic fractures in pediatric major blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

Pelvic fracture urethral defects associated with urethrorectal fistulas are rare and difficult to repair. The aim of this study was to evaluate the efficacy of transperineal urethroplasty with gracilis muscle interposition for the repair of pelvic fracture urethral defects associated with urethrorectal fistulas. We identified 32 patients who underwent transperineal urethroplasty with gracilis muscle interposition to repair pelvic fracture urethral defects associated with urethrorectal fistulas. Patient demographics as well as preoperative, operative and postoperative data were obtained. Mean followup was 33 months (range 6 to 64). The overall success rate was 91% (29 of 32 cases). One-stage repair was successful in 17 of 18 patients (94%) using perineal anastomosis with separation of the corporeal body and in 12 of 14 (86%) using perineal anastomosis with inferior pubectomy and separation of the corporeal body. All 22 patients (100%) without a previous history of repair were successfully treated. However, only 7 of 10 patients (70%) with a previous history of failed urethroplasty and urethrorectal fistula repair were cured. Recurrent urethral strictures developed in 2 cases. One patient was treated successfully with optical internal urethrotomy and the other was treated successfully with tubed perineoscrotal flap urethroplasty. Recurrent urethrorectal fistulas associated with urethral strictures developed in an additional patient. Transperineal urethroplasty with gracilis muscle interposition is a safe and effective surgical procedure for most pelvic fracture urethral defects associated with urethrorectal fistulas. Several other factors may affect its postoperative efficiency. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

Pelvic packing or angiography: competitive or complementary?

PubMed

Suzuki, Takashi; Smith, Wade R; Moore, Ernest E

2009-04-01

Pelvic angiography is an established technique that has evolved into a highly effective means of controlling arterial pelvic haemorrhage. The current dominant paradigm for haemodynamically unstable patients with pelvic fractures is angiographic management combined with mechanical stabilisation of the pelvis. However, an effective rapid screening tool for arterial bleeding in pelvic fracture patients has yet to be identified. There is also no precise way to determine the major source of bleeding responsible for haemodynamic instability. In many pelvic fracture patients, bleeding is from venous lacerations which are not effectively treated with angiography to fractured bony surfaces. Modern pelvic packing consists of time-saving and minimally invasive techniques which appear to result in effective control of the haemorrhage via tamponade. This review article focuses on the recent body of knowledge on angiography and pelvic packing. We propose the optimal role for each modality in trauma centres.

The purpose of this study was to compare the results of immediate and delayed percutaneous sacroiliac screws surgery for unstable pelvic fractures, regarding technical results and complication rate. Retrospective study. The study was conducted at the Soroka University Medical center, Beer Sheva, Israel, which is a level 1 trauma Center. 108 patients with unstable pelvic injuries were operated by the orthopedic department at the Soroka University Medical Center between the years 1999-2010. A retrospective analysis found 50 patients with immediate surgery and 58 patients with delayed surgery. Preoperative and postoperative imaging were analyzed and data was collected regarding complications. All patients were operated on by using the same technique-percutaneous fixation of sacroiliac joint with cannulated screws. The study's primary outcome measure was the safety and quality of the early operation in comparison with the late operation. A total of 156 sacroiliac screws were inserted. No differences were found between the immediate and delayed treatment groups regarding technical outcome measures (P value = 0.44) and complication rate (P value = 0.42). The current study demonstrated that immediate percutaneous sacroiliac screw insertion for unstable pelvic fractures produced equally good technical results, in comparison with the conventional delayed operation, without additional complications.

Management of genitourinary injuries in patients with pelvic fractures.

Weems, W L

Associated injuries frequently occur in patients who sustain fractures of the pelvis. Hemorrhage from intrapelvic vessels, rupture of the urinary bladder and avulsion of the membranous urethra in males are among the integral risks in this trauma. Non-operative methods of managing hemorrhage have gained favor in recent experience. The case records of 282 male patients with pelvic fractures were reviewed to evaluate experience with lower genitourinary injuries. Early recognition is important in bladder injuries, and surgical repair is advised, except in selected patients who may be managed by catheter drainage alone. Delayed complications of bladder injury are rare. Membranous urethral injuries entail a high risk of chronic stricture disease and sexual impotence. The rationale of early repair versus delayed repair of these injuries is discussed. The results in this series show advantage for delayed repair. Images Fig. 2. Fig. 3. PMID:453943

Adrenalin-seeking airborne sports like BASE-jumping, paragliding, parachuting, delta-gliding, speedflying, and skysurfing are now firmly with us as outdoor lifestyle activities and are associated with a high frequency of severe injuries, especially to the spine. Retrospective analysis of all airborne sports-associated spinal and pelvic injuries admitted to a Level I trauma centre in the Swiss Alps between 1st March 2000 and 31st October 2009. Spinal injuries were classified by the Magerl system and pelvic injuries by the AO/OTA scheme modified by Isler and Ganz. Spino-pelvic dissociation fractures in airborne sports were compared to similar injuries in the general trauma population using multiple logistic regression analysis. 181 patients (11 BASE-jumpers, 144 paragliders, 19 parachuters, 1 speedflyer, 4 deltagliders, 2 skysurfer) were included. 161 (89%) were male. Median age was 37.0 years (IQR=29.0-47.0) and ISS 8 (IQR=4-13). 89 (49.2%) patients sustained spinal fractures. Type A fractures were predominant (91.5%), followed by Type C (5.3%) and Type B (3.2%). The level L1 was most often affected (35.1%). 17 patients (9.4%) had pelvic ring fractures. Most frequent were Type C fractures (41.2%), followed by Types A and B (29.4% each). 8 paragliders (4.4%) suffered spino-pelvic dissociation injuries. The odds ratio for sustaining such fractures in paragliders was 21-fold higher (OR 21.04, 95% CI 7.83-56.57, p<0.001) than in the general trauma population. Serious spinal and pelvic injuries account for most injuries sustained during airborne sporting activities. The thoracolumbar region was most often affected, but the lumbopelvic junction is also especially vulnerable as high impact forces from vertical and horizontal deceleration need to be absorbed. The frequency of spino-pelvic dissociation was very high in paragliding injuries, with a 21-fold higher odds ratio than in the general trauma population. Copyright © 2011 Elsevier Ltd.

We describe the presentation, diagnostic evaluation, management and outcome of female urethral trauma. All female patients treated at Harborview Medical Center between 1985 and 2001 with urethral injury were identified by International Classification of Diseases 9th revision code. Approval of the Human Subject Division was obtained and patient charts were reviewed. The Urogenital Distress Inventory Short Form, the Incontinence Impact Questionnaire Short Form and the Female Sexual Function Index were sent to the patients. A total of 25 patients (13 adults, 12 children) with a mean age of 22 years (range 4 to 67) met inclusion criteria. All had pelvic fracture related to blunt trauma. They represented 6% of all female patients treated in the same review period with pelvic fracture. Blood was seen at the introitus in 15 patients and 19 had gross hematuria. Of the injuries 9 were avulsions, 15 were longitudinal lacerations and 1 was not further specified. Primary repair was performed in 21 patients and 4 were treated nonoperatively. There were 5 patients who required secondary procedures including fistula repair in 4 and continent urinary diversion in 1. At a mean followup of 7.3 years (range 1.6 to 14.4) 9 of 21 patients (43%) had moderate or severe lower urinary tract symptoms and 8 of 13 (38%) had sexual dysfunction (FSFI score less than 26.55). Female urethral and bladder neck injury occurs with pelvic fracture, presents with gross hematuria and/or blood at the introitus, and requires operative repair for avulsions and longitudinal lacerations. These patients are at risk for significant sexual and lower urinary tract dysfunction.

A prospective single-cohort study of 31 patients surgically treated for pelvic injuries with displaced sacral fractures. To describe the medium term functional outcome in unstable sacral fractures. Displaced sacral fractures pose a special challenge in orthopedic surgery due to the high rate of associated injuries. Little information is available on the medium-term functional outcome of patients with injuries which include unstable sacral fractures. We examined 31 patients with displaced sacral fractures having 10 mm or more displacement, 1 year (mean, 1.4 years; range, 1.0-2.5 years) after injury. Data from a previous study were supplemented with functional outcome measures (work status, independence in ADL, and SF-36). An association between outcome and tested variables was sought. Fifteen months after injury, 65% of the patients had regained their independence in functions pertaining to daily activities; 33% had returned to work. All dimensions of perceived health were affected. Polytrauma and impairments relative to voiding and sexual function had a detrimental effect on outcome. Fracture characteristics were not predictive of poor outcome. Although the majority of patients achieved independent living, medium-term follow-up indicated significant residual disability. The complex nature of these fractures and the associated injuries should be considered in the rehabilitation of these patients.

Fat embolism is a common complication of pelvic and long bone fractures. Macroscopic fat emboli in the pulmonary arteries on computed tomography have been reported postoperatively after fixation of long bone fractures for trauma, however the quantification of attenuation values of fat emboli have been infrequently reported in the literature. We present a case of pulmonary fat embolism in a 52-year-old female after acute bony trauma sustained during a motor vehicle accident. To the authors' knowledge however, pulmonary fat embolism has not been described on the initial trauma CT scan.

During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all incidence of injury was 13.5 per cent (bladder 9 per cent, urethra 3.5 per cent and combined 1 per cent). Limited extraperitoneal bladder ruptures were treated successfully by Foley catheter drainage.

Pelvic fracture urethral injuries: the unresolved controversy.

PubMed

Koraitim, M M

1999-05-01

The unresolved controversies about pelvic fracture urethral injuries and whether any conclusions can be reached to develop a treatment plan for this lesion are determined. All data on pelvic fracture urethral injuries in the English literature for the last 50 years were critically analyzed. Studies were eligible only if data were complete and conclusive. The risk of urethral injury is influenced by the number of broken pubic rami as well as involvement of the sacroiliac joint. Depending on the magnitude of trauma, the membranous urethra is first stretched and then partially or completely ruptured at the bulbomembranous junction. Injuries to the prostatic urethra and bladder neck occur only in children. Injury to the female urethra usually is a partial tear of the anterior wall and rarely complete disruption of the proximal or distal urethra. Diagnosis depends on urethrography in men and on a high index of suspicion and urethroscopy in women. Of the 3 conventional treatment methods primary suturing of the disrupted urethral ends has the greatest complication rates of incontinence and impotence (21 and 56%, respectively). Primary realignment has double the incidence of impotence and half that of stricture compared to suprapubic cystostomy and delayed repair (36 versus 19 and 53 versus 97%, respectively, p <0.0001). In men surgical and endoscopic procedures do not compete but rather complement each other for treatment of different injuries under different circumstances, including indwelling catheter for urethral stretch injury, endoscopic stenting or suprapubic cystostomy for partial rupture, endoscopic realignment or suprapubic cystostomy for complete rupture with a minimal distraction defect and surgical realignment if the distraction defect is wide. Associated injury to the bladder, bladder neck or rectum dictates immediate exploration for repair but does not necessarily indicate exploration of the urethral injury site. In women treatment modalities are dictated by

Urethral stricture disease, pelvic fracture urethral injury (PFUI), and their various treatment options are associated with erectile dysfunction (ED). The etiology of urethral stricture disease is multifactorial and includes trauma, inflammatory, and iatrogenic causes. Posterior urethral injuries are commonly associated with pelvic fractures. There is a spectrum in the severity of both conditions and this directly impacts the treatment options offered by the surgeon. Many published studies focus on the treatment outcomes and the relatively high recurrence rates after surgical repair. This communication reviews the current knowledge of the association between ED and urethral stricture disease, as well as PFUI. The incidence, pathophysiology, and clinical ramifications of both conditions on sexual function are discussed. The treatment options for ED in those patients are reviewed and summarized. © 2015 American Society of Andrology and European Academy of Andrology.

To investigate the feasibility and therapeutic effect of subcutaneous pedicle screw-rod system with modified placement in treatment of Tile B pelvic fractures. From June 2014 to August 2015, 14 patients with Tile B pelvic fractures were treated by subcutaneous pedicle screw-rod system with modified placement in the anterior inferior iliac spine and pubic tubercle. There were 8 males and 6 females, aged from 23 to 65 years with an average of 42 years. Operative time, intraoperative blood loss, fracture healing and postoperative complication were observed and clinical effects were evaluated by Matta reduction standard and Majeed score. All patients were followed up from 8 to 15 months with an average of 10.5 months. Operative time was 25 to 45 min with an average of 32 min;intraoperative blood loss was 10 to 35 ml with an average of 18 ml. All fractures got primary healing and healed time was 9 to 14 weeks with an average of 12.5 weeks. No postoperative incision infection, internal fixation failure and ectopic ossification were found, 4 cases occurred unilateral lateral femoral cutaneous nerve injury and 1 case occurred unilateral femoral nerve paralysis, but all restored finally. According to Matta criteria, reduction was excellent in 7 cases, good in 5 cases, fair in 2 case. According to Majeed score system, the functional evaluation at last follow-up was excellent in 5 cases, good in 7 cases, fair in 2 cases with the average score of 81.50±8.05. Subcutaneous pedicle screw-rod system with modified placement in the anterior inferior iliac spine and pubic tubercle have advantages of strong reduction, less trauma and complications, and is a promising surgical method in the treatment of Tile B pelvic fractures.

Frailty fractures encompass pelvic ring fractures in the elderly--a condition more frequently encountered in women, usually with pre-existing osteoporosis. The incidence of these fractures is increasing, following the increase in average life expectancy. Most of the times, they are the result of a minor injury, of which the patient has little or no recollection; the clinical signs and symptoms, radiological changes and the degree of fracture stability vary greatly. As such, there is a wide range of therapeutic options and one of the most important decisions for the physician is choosing between surgery and conservative treatment. We present the case of an elderly female patient with multiple pelvic ring fractures, and a medical history of cardiovascular disease and osteoporosis; the orthopedic examination recommended conservative treatment which was carried out in the Geriatric Clinic of the "Dr. C.I. Parhon" Hospital. Following the complete physical examination and through geriatric evaluation, a complex therapeutic plan was devised, which included: recovery through physiotherapy, adequate nutrition, psychological support, treatment of the cardiovascular comorbidities and prevention of the consequences of extended bed rest. The treatment lasted for 60 days and the outcome was favorable: decreased bone frailty, mainly through preserving muscle tone and osteoarticular function, correction of malnutrition, improvement of depression and partial recovery of patient's mobility; the results of our therapy made it possible for the patient to return home, where she leaves alone. She will need help with daily household chores, but she intends to continue the recovery therapy as means of increasing her quality of life and independence.

To compare the efficacy and acceptability of combined hormonal vaginal ring with combined oral hormonal pill in women with idiopathic chronic pelvic pain. Randomised prospective interventional trial conducted in 60 women with idiopathic chronic pelvic pain. Women were randomised into two groups of 30 each. In each group, treatment was given for 84 days using either combined vaginal ring or combined oral hormonal pill. Hormonal vaginal ring releases 15mcg of ethinyl estradiol and 120mcg of the etonogestrel per day while the hormonal pill contained 30mcg of ethinyl estradiol and 150mcg of levonorgestrel. There was no ring or pill free week. After every 28 days, pain relief was measured using visual analogue scale (VAS), and verbal rating score (VRS) calculated by summing dysmenorrhea, non-cyclic pelvic pain (NCCP) and deep dyspareunia scores. Side effects, compliance, satisfaction, and user acceptability were also measured. Data was analyzed using various parametric and non-parametric tests. Reduction in mean VAS score at end of treatment in ring group was 6.23 (95% confidence interval [CI], 5.45-7.01; p<0.001) as compared to 5.53 in pill group (95% CI, 4.83-6.23; p<0.001). Reduction in mean VRS score was 5.63 in ring users (95% CI, 4.84-6.42; p<0.001) versus 4.36 in pill users (95% CI, 3.63-5.10; p<0.001). A significantly higher persistent relief in NCPP score was observed in vaginal ring group as compared to oral pill group at end of one month after stopping treatment. Compliance, satisfaction, and user acceptability were higher in ring users (80%) than pill users (70%) and a higher incidence of nausea was seen in pill group. Present study demonstrates for first time that both vaginal and oral hormonal therapy are effective in treatment of idiopathic chronic pelvic pain and vaginal ring may be a better choice with higher satisfaction rate and fewer side effects.

To determine, using 3 groups of evaluators of varying experience reading orthopedic CT studies, if 3-dimensional computed tomography (3D-CT) provides a more accurate and time efficient method for diagnosis of canine sacral and pelvic fractures, and displacements of the sacroiliac and coxofemoral joints compared with 2-dimensional computed tomography (2D-CT). Retrospective clinical and prospective study. Dogs (n = 23): 12 dogs with traumatic pelvic fractures, 11 canine cadavers with pelvic trauma induced by a lateral impactor. All dogs had a 2D-CT exam of the pelvis and subsequent 3D-CT reconstructions from the 2D-CT images. Both 2D-CT and 3D-CT studies were anonymized and randomly presented to 2 veterinary radiologists, 2 veterinary orthopedic surgeons, and 2 veterinary medical students. Evaluators classified fractures using a confidence scale and recorded the duration of evaluation for each modality and case. 3D-CT was a more time-efficient technique for evaluation of traumatic sacral and pelvic injuries compared with 2D-CT in all evaluator groups irrespective of experience level reading orthopedic CT studies. However, for radiologists and surgeons, 2D-CT was the more accurate technique for evaluating sacral and pelvic fractures. 3D-CT improves sacral and pelvic fracture diagnosis when added to 2D-CT; however, 3D-CT has a reduced accuracy for evaluation of sacral and pelvic fractures if used without concurrent evaluation of 2D-CT images. © Copyright 2014 by The American College of Veterinary Surgeons.

This study aimed to develop a tool in identifying traumatized children at low risk of pelvic fracture and to determine the sensitivity of this low-risk model for pelvic fractures. We hypothesized that the proportion of children without predictors with pelvic fracture is less than 1%. This is a retrospective trauma registry analysis of previously healthy children 1 year to 17 years old presenting to the pediatric emergency department with blunt trauma. Postulated predictors of pelvic fracture on radiograph or computed tomography included pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, Glasgow Coma Scale (GCS) score of 13 or lower, and hemodynamic instability. We used multivariable logistic regression to identify independent predictors of fracture. Of 1,121 eligible patients (mean [SD] age, 8.5 [4.6] years), 87 (7.8%) had pelvic fracture. Independent predictors included pain/abnormal examination result of the pelvis/hip (odds ratio [OR], 16.7; 95% confidence interval [CI], 9.6-29.1), hematuria (OR, 6.6; 95% CI, 3.0-14.6), femoral deformity (OR, 5.9; 95% CI, 3.1-11.3), GCS score of 13 or lower (OR, 2.4; 95% CI, 1.3-4.3), and hemodynamic instability (OR, 3.4; 95% CI, 1.7-6.9). One of 590 children (0.2%; 95% CI, 0-0.5%) without predictors had pelvic fractures versus 86 (16.2%) of 531 in those with one or more predictors (OR, 119; 95% CI, 16.6-833). One of 87 children with pelvic fractures had no predictors (1.1%; 95% CI, 0-3%). When assuming a 100% radiography rate, this tool saves 53% pelvic radiographs. Children with multiple blunt trauma without pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, GCS score of 13 or lower, or hemodynamic instability constitute a low-risk population for pelvic fracture, with less than 0.5% risk rate. This population does not require routine pelvic imaging. Therapeutic study, level IV.

To report our experience of bladder neck injuries, which are a well recognized but rare consequence of pelvic fracture-related trauma to the lower urinary tract, as we have been unable to find any reference in the English literature to their specific nature, cause and management in adults. In the last 10 years we have treated 15 men with bladder neck injuries after pelvic fracture. Two were treated at our centre by delayed primary repair. Thirteen were initially treated elsewhere and presented to us 3 months to 5 years after their injury with intractable incontinence and various other symptoms most notably recurrent urinary infection and gross haematuria. Twelve of the injuries were at or close to the anterior midline and associated with lateral compression fractures or 'open-book' injuries. Five of them were confined to the bladder neck and prostatic urethra; the other seven extended into the subprostatic urethra. Four of these were associated with a coincidental typical rupture of the posterior urethra. All had an associated cavity involving the anterior disruption of the pelvic ring. Two of the injuries, following particularly severe trauma, were a simultaneous complete transection of the bladder neck and of the bulbo-membranous urethra with a sequestered prostate between. We have seen this in children before but not in adults. Another injury, also after particularly severe trauma, was an avulsion of the anterior aspect of the prostate. We have not seen this described before. Fourteen patients underwent lower urinary tract reconstruction and one underwent a Mitrofanoff procedure. All of the 14 had a layered reconstruction of the prostate and bladder neck and in 13, this was supplemented with an omental wrap. In all patients with an anterior midline rupture, the primary injury appeared to be to the prostate and prostatic urethra with secondary involvement of the bladder neck and the subprostatic urethra. The Mitrofanoff procedure was successful. Of the 14

The results of various immediate treatments of urethral injuries complicating a fractured pelvis were evaluated. The records of 100 male patients with pelvic fracture urethral injury were reviewed, 73 of whom were treated by suprapubic cystostomy and delayed repair, 23 by primary realignment and 4 by primary suturing. Also, the findings of 771 patients reported in the literature were reviewed. Urethral stricture was an almost inevitable consequence (97% of the cases) after suprapubic cystostomy. Primary realignment decreased the incidence of stricture to 53% but produced a 36% impotence rate. Primary suturing also decreased the incidence of stricture to 49% but produced the greatest complication rates for impotence (56%) and incontinence (21%). Suprapubic cystostomy alone is indicated for incomplete urethral rupture, slight urethral distraction and critically unstable patients, and when there are inadequate facilities or inexperienced surgeons. Primary realignment is advised if there is wide separation of the urethral ends, or associated injury of the bladder neck or rectum. Primary suturing is not recommended for any condition.

Emergency primary repair of grade V bladder neck injury complicating pelvic fracture

We report a case of a grade V bladder injury complicating an open-book pelvic fracture following a road traffic accident. The bladder neck injury was primarily repaired in the emergency setting of a poor-resourced area with successful outcome. The dangers of urinary extravasation are still to be considered of importance and we advocate and encourage immediate/emergency open intervention although it remains controversial to say the least in a lesser resourced healthcare set up.

In the evaluation of haemorrhage in trauma patients with pelvic fractures, contrast extravasation (CE) on computed tomography (CT) scan often implies active arterial bleeding. However, the absence of CE on CT scan does not always exclude the need for transcatheter arterial embolisation (TAE) to achieve haemostasis. In the current study, we evaluated the factors associated with the need for TAE in patients without CE on CT scan. These factors may be evaluated as adjuncts to CT scanning in the management of patients with pelvic fractures. We retrospectively reviewed our trauma registry and medical records of patients with pelvic fractures. When CE was observed, indicating active haemorrhage, the patients underwent TAE to achieve haemostasis. In contrast, patients without CE were held for observation and treatment of their injuries, and if their condition deteriorated after a delayed interval, they were then also referred for TAE if no other focus of haemorrhage was found. Patients without CE on CT scan but with retroperitoneal haemorrhage requiring TAE were investigated. Their demographic characteristics, associated injuries, fracture patterns, and changes in systolic blood pressure were described and analysed. In total, 201 patients with pelvic fracture underwent CT scan examination; 47 (23.4%) had CE by CT scan, whereas the other 154 (76.6%) did not. Of the 154 patients who did not show CE by CT scan, 124 (80.5%) patients never underwent TAE; however, 30 (19.5%) of these patients did eventually undergo TAE. In comparing the patients who underwent TAE to those who did not undergo TAE among patients without CE on CT scan, the systolic blood pressure (SBP) on arrival (median: 100.0 mmHg vs 136.0 mmHg, p<0.01) and the lowest SBP recorded in the ED (median: 68.0 mmHg vs 129.0 mmHg, p<0.01) were significantly lower in the patients who underwent TAE. The ROC curve analysis revealed that the most appropriate cutoff value of decrement of SBP (SBP on arrival minus the lowest

Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain. Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.3) that had healed were included. Foreign patients and those with an associated spinal or acetabular fracture or nonunion were excluded. The review consisted of subjective questionnaires, a clinical examination, and standing A/P and lateral stereoradiographic views. The pelvic tilt (PT), sacral slope (SS), pelvic incidence (PI), measured lumbar lordosis (LLm), T9 sagittal offset, leg discrepancy (LD) and lateral curvature (LC). The expected lumbar lordosis (LLe) was calculated using the formula LLe=PI+9°. We defined lumbopelvic mismatch (LPM) as the difference between LLm and LLe being equal or greater than 25% of LLe. Fifteen patients were reviewed after an average follow-up of 8.8 years [5.4-15]. There were four Tile C1, five Tile C2, five Tile C3 and one Tile A3.3 fracture. Ten of the 15 patients had low back pain. The mean angles were: LLm 49.6° and LLe 71.9° (P=0.002), PT 21.3°, SS 44.1°, PI 62.9° in patients with low back pain and LLm 57.4° and LLe 63.2° (P=0.55), PT 13°, SS 43.1°, PI 54.2° in those without. LPM was present in 9 patients, 8 of who had low back pain (P=0.02). Six patients, all of whom had low back pain, had a mean LC of 7.5° [4.5-23] (P=0.02). The mean LD was 0.77cm. The findings of this small study suggest that patients who experience low back pain after their posterior arch of the pelvic ring fracture has healed, have a lumbopelvic mismatch. Early treatment of these patients should aim to reestablish the anatomy of the pelvic base relative to the frontal and sagittal balance. IV. Copyright © 2017 Elsevier Masson SAS.

Traumatic injury to the pelvic ring is a result of high energy trauma in young patients. These osteo-ligamentous injuries are associated with numerous lesions including retroperitoneal hematoma, urogenital, cutaneous and neurological (lumbosacral plexus). The goal of initial management is to restore vital indicators, urinary excretion function and protect the patient from infectious complications. An emergency decisional algorithm helps manage haemodynamic instability. Initial bone and ligament procedures should reduce displacement and make it possible for the patient the wait until his condition is stable enough for definitive surgical fixation. The goal of surgical treatment is to avoid nonunion and malunion. Stable fixation of the posterior arch after reduction favors union. Different techniques can be used by the posterior, anterior ilio-inguinal or lateral percutaneous approaches. Anterior fixation is discussed to improve reduction and increase the stability obtained with a posterior procedure. Anterior external fixation is useful to temporarily reinforce posterior stabilization. Copyright © 2013. Published by Elsevier Masson SAS.

To explore the effectiveness of open reduction and internal fixation through anterior and posterior approaches in treatment of open Tile type C pelvic fractures at early stage. Between January 2009 and April 2012, 12 patients with open Tile C pelvic fractures were treated. There were 7 males and 5 females, aged 6-53 years (median, 31 years). Of 12 cases, 4 were classified as Tile type C1, 6 as Tile type C2, and 2 as Tile type C3; 5 were rated as Gustilo type II and 7 as Gustilo type III. The injury severity score was 18-57 (mean, 37.2). The interval of injury and admission ranged from 15 minutes to 3 days (median, 50 minutes). The debridement and external fixation were performed at first stage; then open reduction and internal fixation were used through anterior approach (reconstruction plate) and posterior approach (cannulated lag screws). The vacuum sealing drainage was performed during treatment until the wounds healed. Delayed healing of incison was obtained in 12 cases because of wound infection. Anatomical reduction or approximate anatomical reduction was achieved in all 12 cases. The patients were followed up 3-39 months (median, 18 months). No loosening of internal fixation or fracture displacement was observed during follow-up. The fracture healing time was 7-13 weeks (mean, 9.7 weeks). At last follow-up, according to the Matta standard, the outcome was excellent in 10 cases and good in 2 cases; according to Majeed score, the results were excellent in 9 cases, good in 1, and poor in 2. Early internal fixation operation of open Tile type C pelvic fractures can effectively restore the pelvic anatomical structure and stability, reduce the complication, and achieve satisfactory effectiveness.

The aim of this study is to evaluate the efficacy and feasibility of three-dimensional printing (3D printing) assisted internal fixation of unstable pelvic fracture from minimal invasive para-rectus abdominis approach. A total of 38 patients with unstable pelvic fractures were analyzed retrospectively from August 2012 to February 2014. All cases were treated operatively with internal fixation assisted by three-dimensional printing from minimal invasive para-rectus abdominis approach. Both preoperative CT and three-dimensional reconstruction were performed. Pelvic model was created by 3D printing. Data including the best entry points, plate position and direction and length of screw were obtained from simulated operation based on 3D printing pelvic model. The diaplasis and internal fixation were performed by minimal invasive para-rectus abdominis approach according to the optimized dada in real surgical procedure. Matta and Majeed score were used to evaluate currative effects after operation. According to the Matta standard, the outcome of the diaplasis achieved 97.37% with excellent and good. Majeed assessment showed 94.4% with excellent and good. The imageological examination showed consistency of internal fixation and simulated operation. The mean operation time was 110 minutes, mean intraoperative blood loss 320 ml, and mean incision length 6.5 cm. All patients have achieved clinical healing, with mean healing time of 8 weeks. Three-dimensional printing assisted internal fixation of unstable pelvic fracture from minimal invasive para-rectus abdominis approach is feasible and effective. This method has the advantages of trauma minimally, bleeding less, healing rapidly and satisfactory reduction, and worthwhile for spreading in clinical practice.

Posterior locked lateral compression injury of the pelvis in geriatric patients: an infrequent and specific variant of the fragility fracture of pelvis.

Posterior locked lateral compression injury (PLLCI) of the pelvic ring is an infrequent variant of lateral compression injury, a condition described in only eight reported cases since 2000. Lateral compression injury usually results from high-energy trauma and is characterized by locking between the medially translated fractured ilium and the anterior border of the sacrum, regardless of whether the fractured ilium involves the sacroiliac joint. However, in our experience, lateral compression injury can also result from low-energy trauma as a manifestation of pelvic fragility fracture. The aim of the present study was to describe this rare form of PLLCI in a case series of geriatric patients. A retrospective analysis of consecutive patients with pelvic ring injuries who were admitted to our hospital from January 2008 to April 2015 identified seven geriatric patients (1 male and 6 females; median age 81 years) with a form of PLLCI. All injuries were due to falls from a standing position onto the ground. All seven cases demonstrated characteristics of a locking fractured ilium over the anterior border of the sacrum on axial computed tomography images, but were not detected on plain radiographs. All underwent follow-up at 1 year or later with improved mean visual analogue scale scores (range 0-3). Regarding Koval walking ability scores, patients who underwent pelvic brim plating with anterior external fixation were more likely to regain their pre-injury walking ability than patients who only underwent anterior external fixation or conservative treatment. Geriatric patients can experience PLCCIs of the pelvis due to low-energy trauma. These fractures have different characteristics from those associated with severe injuries due to high-energy trauma, and they comprise an infrequent form of Rommens fragility fracture of the pelvis (type IIIa). In these cases, appropriate surgical management that includes sacroiliac plating combined with anterior external fixation can

During Expedition 364, IODP/ICDP drilled the peak ring of the Chicxulub impact crater at Site M0077, recovering core from 505.7 to 1334.7 mbsf. The core has been imaged via X-ray Computer Tomography (CT) as a noninvasive method to create a 3-dimensional model of the core, providing information on the density and internal structure at a 0.3 mm resolution. Results from the expedition show that from 748 mbsf and deeper the peak ring is largely composed of uplifted and fractured granitic basement rocks originally sourced from approximately 8-10 km depth. Impact crater modeling suggests the peak ring was formed through dynamic collapse of a rebounding central peak within 10 minutes of impact, requiring the target rocks to temporarily behave as a viscous fluid. The newly recovered core provides a rare opportunity to investigate the cratering process, specifically how the granite was weakened, as well as the extent of the hydrothermal system created after the impact. Based on the CT data, we identify four classes of fractures based on their CT facies deforming the granitoids: pervasive fine fractures, discrete fine fractures, discrete filled fractures, and discrete open fractures. Pervasive fine fractures were most commonly found proximal to dikes and impact melt rock. Discrete filled fractures often displayed a cataclastic texture. We present density trends for the different facies and compare these to petrophysical properties (density, NGR, P-wave seismic velocity). Fractured areas have a lower density than the surrounding granite, as do most filled fractures. This reduction suggests that fluid migrating through the peak ring in the wake of the impact either deposited lower density minerals within the fractures and/or altered the original fracture fill. The extent and duration of fluid flow recorded in these fractures will assist in the characterization of the post-impact hydrothermal system. Future work includes combining information from CT images with thin sections

The surgical treatment of pelvic and acetabular fractures can be technically challenging. Various techniques are available for the reconstruction of pelvic and acetabular fractures. Less invasive percutaneous fracture stabilization techniques, with closed reduction or limited open reduction, have been developed and are gaining popularity in the management of pelvic and acetabular fractures. These techniques require knowledge and interpretation of various fluoroscopic images to ensure appropriate and safe screw placement. Given the anatomic complexity of the intrapelvic structures and the 2-dimensional nature of standard fluoroscopy, multiple images oriented in different planes are needed to assess the accuracy of guide wire and screw placement. This article reviews the fluoroscopic imaging of common screw orientations during pelvic and acetabular surgery.

Pelvic ring injuries and sacroiliac dislocations have significant impacts on patient's quality of life. Several techniques have been described for posterior pelvic fixation. The current study has been designed to evaluate the spinopelvic method of fixation for sacroiliac fractures and fracture-dislocations. Between January 2006 and December 2014, 14 patients with sacroiliac joint fractures, dislocation and fracture-dislocation were treated by Spinopelvic fixation at Shahid Sadoughi Training Hospital, Yazd, Iran. Patients were seen in follow up, on average, out to 32 months after surgery. Computed tomographic (CT) scans of patients with sacral fractures were reviewed to determine the presence of injuries. A functional assessment of the patients was performed using Majeed's score. Patient demographics, reduction quality, loss of fixation, outcomes and complications, return to activity, and screw hardware characteristics are described. The injury was unilateral in 11 (78.5%) patients and bilateral in 3 (21.5%). Associated injuries were present in all patients, including fractures, dislocation and abdominal injuries. Lower limb length discrepancy was less than 10 mm in all patients except two. Displacement, as a measure of quality of reduction was less than 5 mm in 13 patients. The mean Majeed score was 78/100. Wound infection and hardware failure were observed in 3 (21.4%) and 1 (7.1%) cases, respectively. In this study most patients (85%) return to work postoperatively. According to the findings, spinopelvic fixation is a safe and effective technique for treatment of sacroiliac injuries. This method can obtain early partial to full weight bearing and possibly reduce the complications.

Trauma injuries of the posterior urethra resulting from pelvic fracture in children tend to be complete ruptures, with upper dislocation of the prostate. This paper aims to show our experience in using an anterior sagittal transanorectal approach (ASTRA) in the treatment of such injuries. The medical records of 11 patients with pelvic fracture urethral distraction defects who had undergone anastomotic urethroplasty through ASTRA between 1997 and 2009 were reviewed. Ages ranged from 1 year and 6 months to 23 years (mean age 11 years). Of the 11 patients, 8 had previously undergone failed urethroplasties. In 10 patients it was possible to perform tension free urethroplasty. One patient required inferior pubectomy and separation of the corpora cavernosa. Patients' follow-up time varied from 10 months to 10 years and 9 months (mean 41 months). One patient had a urethral fistula and evolved with a urethral diverticulum successfully managed by diverticulectomy. One patient presented a urethral stenosis managed by urethral dilatation. Of the 11 patients, 9 presented functional urethral flow and are continent. Two patients had no urethral flow. One is undergoing bladder catheterization through the Mitrofanoff principle and the other one through the urethra. No patient presented fecal incontinence or rectourethral fistula. This access, which is increasingly being used to approach posterior urethral diseases, has proved to be safe and effective in the treatment of pelvic fracture urethral distraction defects.

Con: bulbomembranous anastomotic urethroplasty for pelvic fracture urethral injuries

PubMed Central

Tausch, Timothy J.

2015-01-01

Current literature remains controversial regarding whether to treat patients sustaining pelvic fracture urethral injuries (PFUIs) with primary endoscopic realignment (PER) versus suprapubic tube (SPT) placement alone with elective bulbomembranous anastomotic urethroplasty (BMAU). Success rates for PER following PFUI are wide-ranging, depending on various authors’ definitions of what defines a successful outcome. At our institution, for SPT/BMAU patients, the mean time to definitive resolution of stenosis was dramatically shorter compared to PER cases. The vast majority of PER patients required multiple endoscopic urethral interventions and/or experienced various other adverse events which were rarely noted among the SPT/BMAU group. While PER does occasionally result in urethral patency without the need for further intervention, the risk of delay in definitive treatment and potential for adverse events has led to a preference for SPT and elective BMAU at our institution.

The aim of this study is to evaluate the effects of the different immediate treatment modalities on the sexual and voiding functions in pelvic fracture urethral injuries. The records of 38 male patients with traumatic posterior urethral injuries were reviewed, 18 of whom were treated by initial suprapubic cystostomy and delayed repair (Group 1), and 20 by primary urethral realignment (Group 2). Types of pelvic fractures and urethral injuries were classified according to surgical and radiological findings. Long-term voiding functions were determined by the patient questionnaire, residual urine and uroflow. Sexual functions were also determined by the patient questionnaire and a penile duplex ultrasound study. Mean follow-ups of Groups 1 and 2 were 37 and 39 months, respectively. Membranous urethral disruption extending to the urogenital diaphragm was the most frequent urethral injury (type 3), with incidences of 66.7% and 77.7%, respectively. There were no statistically significant differences in mean age, incidence of pelvic fracture types and urethral injury types between groups (p > 0.05). After the immediate treatments, 16.7% and 55% of the patients regained normal urination, and stricture developed in 83.3% and 45% of the patients, respectively. In 44.4% of the patients in Group 1 and 10% in Group 2, urethral strictures required open urethroplasty (p < 0.05). Erectile impotence before urethroplasty in 17.6% and 20%, anejaculation after urethroplasty in 17.6% and 15% and incontinence in 5.6% and 10% of the patients were found in Groups 1 and 2, respectively (p > 0.05). However, 88.8% and 90% of patients eventually achieved normal urination with complete continence. Sexual and voiding dysfunction after pelvic fracture posterior urethral injury seem to be the result of the injury itself, not of the immediate treatment modalities. In urethral disruption injuries, primary urethral realignment seems more favourable than suprapubic cystostomy and delayed repair.

Bulboprostatic anastomotic urethroplasty was performed in 20 children with posterior urethral strictures secondary to bony pelvic fractures. The approach was perineal in 4 children and transpubic abdominoperineal in 16, with good postoperative results in 100 and 62.5%, respectively. In some children the urethral disruption occurred within the prostate itself and not at the prostatomembranous junction. In such cases the proximal sphincteric mechanism may be at risk and immediate repair of the injury is advisable. In the case of common prostatomembranous disruption displacement of the urethra may be significant. In such cases a transpubic approach is preferable. If the proximal sphincteric mechanism is deranged, it can be managed at the same time.

Pelvic fracture and injury to the lower urinary tract.

The presence of a urologic injury must be considered in all patients with pelvic fracture. Uroradiographic evaluation starting with retrograde urethrography is indicated in all male patients with concomitant gross hematuria, bloody urethral discharge, scrotal or perineal ecchymosis, a nonpalpable prostate on rectal examination, or an inability to urinate. If the urethra is normal, a catheter may be passed, and in the presence of gross hematuria, a cystogram must be performed. Female patients rarely suffer urethral lacerations. The urethra is examined, and a Foley catheter may be passed without a urethrogram. The immediate management of associated urologic injuries continues to evolve and evoke controversy. Selected cases of extraperitoneal bladder perforation may be safely managed solely by catheter drainage. Intraperitoneal perforations require surgical exploration and repair. Urethral disruption (partial or complete) may be safely managed by primary cystostomy drainage with management of potential complications (stricture, impotence, incontinence) in 4 to 6 months.

Computed tomography (CT) scan with three-dimensional (3D) reconstruction has been used to evaluate complex fractures in pre-operative planning. In this study, rapid prototyping of a life-size model based on 3D reconstructions including bone and vessel was applied to evaluate the feasibility and prospect of these new technologies in surgical therapy of Tile C pelvic fractures by observing intra- and perioperative outcomes. The authors conducted a retrospective study on a group of 157 consecutive patients with Tile C pelvic fractures. Seventy-six patients were treated with conventional pre-operative preparation (A group) and 81 patients were treated with the help of computer-aided angiography and rapid prototyping technology (B group). Assessment of the two groups considered the following perioperative parameters: length of surgical procedure, intra-operative complications, intra- and postoperative blood loss, postoperative pain, postoperative nausea and vomiting (PONV), length of stay, and type of discharge. The two groups were homogeneous when compared in relation to mean age, sex, body weight, injury severity score, associated injuries and pelvic fracture severity score. Group B was performed in less time (105 ± 19 minutes vs. 122 ± 23 minutes) and blood loss (31.0 ± 8.2 g/L vs. 36.2 ± 7.4 g/L) compared with group A. Patients in group B experienced less pain (2.5 ± 2.3 NRS score vs. 2.8 ± 2.0 NRS score), and PONV affected only 8 % versus 10 % of cases. Times to discharge were shorter (7.8 ± 2.0 days vs. 10.2 ± 3.1 days) in group B, and most of patients were discharged to home. In our study, patients of Tile C pelvic fractures treated with computer-aided angiography and rapid prototyping technology had a better perioperative outcome than patients treated with conventional pre-operative preparation. Further studies are necessary to investigate the advantages in terms of clinical results in the short and long run.

Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D) printing techniques for surgical management of old pelvic fractures. First, 16 dried human cadaveric pelvises were used to confirm the anatomical accuracy of the 3D models printed based on radiographic data. Next, nine clinical cases between January 2009 and April 2013 were used to evaluate the surgical reconstruction based on the 3D printed models. The pelvic injuries were all type C, and the average time from injury to reconstruction was 11 weeks (range: 8-17 weeks). The workflow consisted of: (1) Printing patient-specific bone models based on preoperative computed tomography (CT) scans, (2) virtual fracture reduction using the printed 3D anatomic template, (3) virtual fracture fixation using Kirschner wires, and (4) preoperatively measuring the osteotomy and implant position relative to landmarks using the virtually defined deformation. These models aided communication between surgical team members during the procedure. This technique was validated by comparing the preoperative planning to the intraoperative procedure. The accuracy of the 3D printed models was within specification. Production of a model from standard CT DICOM data took 7 hours (range: 6-9 hours). Preoperative planning using the 3D printed models was feasible in all cases. Good correlation was found between the preoperative planning and postoperative follow-up X-ray in all nine cases. The patients were followed for 3-29 months (median: 5 months). The fracture healing time was 9-17 weeks (mean: 10 weeks). No delayed incision healing, wound infection, or nonunions occurred. The results were excellent in two cases, good

To investigate the incidence of and risk factors for pelvic insufficiency fracture (PIF) after definitive chemoradiation therapy for locally advanced cervical cancer (LACC). We analyzed 101 patients with LACC treated from 2008-2014. Patients received weekly cisplatin and underwent external beam radiation therapy with 45 Gy in 25 fractions (node-negative patients) or 50 Gy in 25 fractions with a simultaneous integrated boost of 60 Gy in 30 fractions (node-positive patients). Pulsed dose rate magnetic resonance imaging guided adaptive brachytherapy was given in addition. Follow-up magnetic resonance imaging was performed routinely at 3 and 12 months after the end of treatment or based on clinical indication. PIF was defined as a fracture line with or without sclerotic changes in the pelvic bones. D 50% and V 55Gy were calculated for the os sacrum and jointly for the os ileum and pubis. Patient- and treatment-related factors including dose were analyzed for correlation with PIF. The median follow-up period was 25 months. The median age was 50 years. In 20 patients (20%), a median of 2 PIFs (range, 1-3 PIFs) were diagnosed; half were asymptomatic. The majority of the fractures were located in the sacrum (77%). Age was a significant risk factor (P<.001), and the incidence of PIF was 4% and 37% in patients aged ≤50 years and patients aged >50 years, respectively. Sacrum D 50% was a significant risk factor in patients aged >50 years (P=.04), whereas V 55Gy of the sacrum and V 55Gy of the pelvic bones were insignificant (P=.33 and P=.18, respectively). A dose-effect curve for sacrum D 50% in patients aged >50 years showed that reduction of sacrum D 50% from 40 Gy EQD2 to 35 Gy EQD2 reduces PIF risk from 45% to 22%. PIF is common after treatment of LACC and is mainly seen in patients aged >50 years. Our data indicate that PIFs are not related to lymph node boosts but rather to dose and volume associated with irradiation of the elective pelvic target. Reducing

To compare the efficacy of sacroiliac joint anterior approach with double reconstruction plate and computer assisted navigation percutaneous sacroiliac screw for treating Tile C1 pelvic fractures. Fifty patients with pelvic Tile C1 fractures were randomly divided into two groups ( n =25 for each) in the orthopedic department of West China Hospital of Sichuan University from December 2012 to November 2014. Patients in group A were treated by sacroiliac joint dislocation with anterior plate fixation. Patients in group B were treated with computerized navigation for percutaneous sacroiliac screw. The operation duration,intraoperative blood loss,incision length,and postoperative complications (nausea,vomiting,pulmonary infection,wound complications,etc.) were compared between the two groups. The postoperative fracture healing time,postoperative patient satisfaction,and postoperative fractures MATTA scores (to evaluate fracture reduction),postoperative MAJEED function scores,and SF36 scores of the patients were also recorded and compared. No significant differences in baseline characteristics were found between the two groups of patients. All of the patients in both groups had their operations successfully completed. Patients in group B had significantly shorter operations and lower intraoperative blood loss,incision length and postoperative complications than those in group A ( P <0.05). Patients in group B also had higher levels of satisfaction than those in group A ( P <0.05). No significant differences were found between the two groups in postoperative followup time,fracture healing time,postoperative MATTA scores,postoperative MAJEED function scores and SF36 scores ( P >0.05). Sacroiliac joint anterior approach with double reconstruction plate and computer assisted navigation percutaneous sacroiliac screws are both effective for treating Tile C1type pelvic fractures,with similar longterm efficacies. However,computer assisted navigation percutaneous sacroiliac screw

This study aimed at evaluating the additional stability that is provided by anterior external and internal fixators in an unstable pelvic fracture model (OTA 61-C). An unstable pelvic fracture (OTA 61-C) was created in 27 synthetic pelves by making a 5-mm gap through the sacral foramina (posterior injury) and an ipsilateral pubic rami fracture (anterior injury). The posterior injury was fixed with either a single iliosacral (IS) screw, a single trans-iliac, trans-sacral (TS) screw, or two iliosacral screws (S1S2). Two anterior fixation techniques were utilized: external fixation (Ex-Fix) and supra-acetabular external fixation and internal fixation (In-Fix); supra-acetabular pedicle screws connected with a single subcutaneous spinal rod. The specimens were tested using a nondestructive single-leg stance model. Peak-to-peak (P2P) displacement and rotation and conditioning displacement (CD) were calculated. The Ex-Fix group failed in 83.3 % of specimens with concomitant single-level posterior fixation (Total: 15/18-7 of 9 IS fixation, 8 of 9 TS fixation), and 0 % (0/9) of specimens with concomitant two-level (S1S2) posterior fixation. All specimens with the In-Fix survived testing except for two specimens treated with In-Fix combined with IS fixation. Trans-sacral fixation had higher pubic rotation and greater sacral and pubic displacement than S1S2 (p < 0.05). Rotation of the pubis and sacrum was not different between In-Fix constructs combined with single-level IS and TS fixation. In this model of an unstable pelvic fracture (OTA 61-C), anterior fixation with an In-Fix was biomechanically superior to an anterior Ex-Fix in the setting of single-level posterior fixation. There was no biomechanical difference between the In-Fix and Ex-Fix when each was combined with two levels of posterior sacral fixation.

Review of records from 205 patients with pelvic fracture and hematuria revealed that 121 underwent urologic and radiographic evaluation. Of these patients 20 had severe posterior urethral injuries documented by urethrography of voiding cystourethrography: 9 underwent primary repair and 11 had delayed scrotal-inlay urethroplasty after initial cystostomy alone. Patients who underwent primary repair had a 77 per cent incidence of stricture, a 22 per cent incidence of incontinence and a 33 per cent incidence of impotency. Patients who underwent delayed closure had no incidence of stricture, incontinence or impotence. Patients in both groups had urinary tract infections. Simple cystostomy followed by delayed scrotal-inlay urethroplasty appears superior to primary realignment in the management of patients with posterior urethral injuries.

To investigate clinical efficacy of unstable pelvic fractures in the treatment with percutaneous sacroiliac screws and sacroiliac joint anterior plate fixation. 64 patients with unstable pelvic fractures were selected in the hospital from January 2008 to June 2011, and were randomly divided into two groups.(32 patients with sacroiliac anterior plate fixation as the control group, and another 32 patients with percutaneous sacroiliac screw internal fixation as the observation group). The perioperative period clinical indicators, postoperative Matta score, postoperative Majeed function score of all patients were compared and analyzed. The operation time, intraoperative blood loss, wound total length, postoperative fever time, duration of hospitalization in the observation group were significantly less than those in the control group. The complication rate (3.1%) in the observation group was lower than that in the control group (21.9%). The rate of Matta score excellent (96.9%) in the observation group was higher than that in the control group (81.2%) after the treatment. The rate of Majeed function score excellent (93.8%) in the observation group was significantly higher than that in the control group (75%) after the treatment. Percutaneous sacroiliac screw internal fixation in the treatment of unstable pelvic fractures has less injury, less bleeding, less pain and rapid recovery which is a safe and effective minimally invasive operation method. The clinical curative effect of percutaneous sacroiliac screw internal fixation is better than anterior plate fixation for the treatment of sacroiliac joint. The full preparation before the surgery and patients with positive can substantially reduce the occurrence of complications rate.

managed non-operatively. On trauma MDCT examinations, patients with SPD have characteristic fracture patterns. It is important to differentiate SPD from other pelvic ring injuries due to high rate of associated injuries. Although all SPD injuries are unstable and need fixation, the decision for operative management in an individual patient depends on the systemic injury pattern, specific fracture pattern, and the ability to attain stable screw fixation.

To assess agreement between ultrasonography (transcutaneous and transrectal) and standing radiography in horses with fractures in the pelvic region and disorders of the coxofemoral joint. Case series. Warmblood horses (n=23) and 2 ponies. Medical records (1999-2008) of equids with pelvic or coxofemoral disorders that had pelvic radiography and ultrasonography were retrieved and results of both techniques compared. Radiography and ultrasonography each identified equal numbers of fractures of the tuber coxa (n=4), ilial shaft (2), ischium (3), femoral neck (2), and osteoarthritis/osis of the coxofemoral joint (6). Fractures of the ilial wing (4) were only identified by ultrasonography not by standing radiography. Of 9 acetabular fractures, 3 were identified on radiographs only, 5 were identified with both modalities. One pubic fracture was identified using ultrasonography and radiography. One acetabular and 1 pubic fracture were only diagnosed on necropsy. We found reasonable agreement (73%; 24/33) between ultrasonography and standing radiography for diagnosis of pelvic-femoral disorders. Ultrasonography was more useful for ilial wing fractures and radiography for acetabular fractures. Ultrasonography is a rapid, safe imaging technique for detecting disorders of the pelvic region with a high diagnostic yield and is a preferred initial approach in horses with severe hindlimb lameness.

Gross dissection for demonstrating anatomy of the human pelvis has traditionally involved one of two approaches, each with advantages and disadvantages. Classic hemisection in the median plane through the pelvic ring transects the visceral organs but maintains two symmetric pelvic halves. An alternative paramedial transection compromises one side of the bony pelvis but leaves the internal organs intact. The authors propose a modified technique that combines advantages of both classical dissections. This novel approach involves dividing the pubic symphysis and sacrum in the median plane after shifting all internal organs to one side. The hemipelvis without internal organs is immediately available for further dissection of the lower limb. The hemipelvis with intact internal organs is ideal for showing the complex spatial relationships of the pelvic organs and vessels relative to the intact pelvic floor.

Scientific research is an essential aspect in the ongoing development of medical education and improved patient care. Dissemination of findings is a pivotal goal of any health research study. The number of citations that a published article receives is reflective of the importance that paper has on clinical practice. To date, it is unknown which journals are most frequently cited as influencing the management of pelvic trauma. The aim of this study was to identify the top 50 publications relating to the management of pelvic trauma. The database of the Science Citation Index of the Institute for Scientific Information (1945 to 2016) was reviewed to identify the 50 papers most commonly cited. A total of 1535 papers were included. Of these, 31 papers were cited over 100 times with the top 50 cited 69 times or more. The top 50 were subjected to further analysis to identify the authors and institutions involved. The majority of these publications originated in the USA, followed by Canada. The most cited paper is "pelvic ring fractures-should they be fixed", published by Tile in 1988. We have identified and analysed the publications that have contributed most to the assessment and management of pelvic trauma over the past 50 years. We have also identified the researchers and institutions which have most influenced the evidence-based approach currently employed in the management of pelvic trauma.

Sudden emotions may interfere with mechanisms for keeping balance among the elderly. The aim of this study is to analyse if emotional stress and specifically feelings of anger, sadness, worries, anxiety or stress, can trigger falls leading to hip or pelvic fracture among autonomous older people. The study applied the case-crossover design and was based on data gathered by face to face interviews carried out in Stockholm between November 2004 and January 2006 at the emergency wards of two hospitals. Cases (n = 137) were defined as persons aged 65 and older admitted for at least one night due to a fall-related hip or pelvic fracture (ICD10: S72 or S32) and meeting a series of selection criteria. Results are presented as relative risks with 95% confidence intervals. There was an increased risk for fall and subsequent hip or pelvic fracture for up to one hour after emotional stress. For anger there was an increased relative risk of 12.2 (95% CI 2.7-54.7), for sadness of 5.7 (95% CI 1.1-28.7), and for stress 20.6 (95% CI 4.5-93.5) compared to periods with no such feelings. Emotional stress seems to have the potential to trigger falls and subsequent hip or pelvic fracture among autonomous older people. Further studies are needed to clarify how robust the findings are - as the number of exposed cases is small - and the mechanisms behind them - presumably balance and vision impairment in stress situation.

Pelvic fractures constitute a major cause of death and residual disability in motor vehicle collisions (MVC). To date there has been poor documentation of the epidemiology of severe pelvic injuries. A detailed retrospective examination of all abbreviated injury score (AIS) > or = 4 pelvic fractures sustained in occupants of MVCs seen at this lead trauma hospital over the last 12 years and in the province of Ontario over the last 6 years was completed. The regional trauma centre registry and provincial database were used to obtain demographics, injuries, course in hospital and crash data on patients sustaining AIS > or = 4 pelvic injuries between May 1988 and April 2000. Data was analysed for drivers (D), front (FP) and rear (RP) passengers in 4-year blocks. Means (S.D.) with t-test for continuous and chi2 for categorical data were used for analysis. AIS > or = 4 pelvic fractures increased significantly in D and FP over 12 years and in RP over the last 8 years. Similar significant increases were seen throughout the province over the last 6 years. No significant change in age, sex, ISS or referral patterns was seen. Lateral impact collisions also increased over the study duration. Occupants with pelvic injury compared to all MVC survivors ISS > or = 16 during the same study period had a higher ISS (P < 0.001), utilised more blood in 24h and in total (P < 0.001) and died more frequently (P < 0.001). However, significantly fewer required ICU support (P < 0.01) which may reflect the associated injuries. Patients with pelvic fractures had significantly fewer head and chest injuries as well as fewer face and neck injuries. They did have significantly more injuries in the region of the pelvis including lumbar and sacral spine fractures, genitourinary, liver, spleen and lower extremity blood vessel, nerve and bone injuries. This study documented an increasing incidence of severe pelvic injury resulting from MVCs. This may be related to an associated increase in the

The S1 and S2 corridors are the typical osseous pathways for iliosacral screw fixation of posterior pelvic ring fractures. In dysmorphic sacra, the S1 screw trajectory is often different from that in normal sacra. We present a case of iliosacral screw placement in the third sacral segment for fixation of a complex lateral compression type-3 pelvic fracture in a patient with a dysmorphic sacrum. In patients with dysmorphic sacra and unstable posterior pelvic ring fractures or dislocations, the S3 corridor may be a feasible osseous fixation pathway that can be used in a manner equivalent to the S2 corridor in a normal sacrum.

We have recently developed a subcutaneous anterior pelvic fixation technique (INFIX). This internal fixator permits patients to sit, roll over in bed and lie on their sides without the cumbersome external appliances or their complications. The purpose of this study was to evaluate the biomechanical stability of this novel supraacetabular pedicle screw internal fixation construct (INFIX) and compare it to standard internal fixation and external fixation techniques in a single stance pelvic fracture model. Nine synthetic pelves with a simulated anterior posterior compression type III injury were placed into three groups (External Fixator, INFIX and Internal Fixation). Displacement, total axial stiffness, and the stiffness at the pubic symphysis and SI joint were calculated. Displacement and stiffness were compared by ANOVA with a Bonferroni adjustment for multiple comparisons The mean displacement at the pubic symphysis was 20, 9 and 0.8 mm for external fixation, INFIX and internal fixation, respectively. Plate fixation was significantly stiffer than the INFIX and external Fixator (P = 0.01) at the symphysis pubis. The INFIX device was significantly stiffer than external fixation (P = 0.017) at the symphysis pubis. There was no significant difference in SI joint displacement between any of the groups. Anterior plate fixation is stiffer than both the INFIX and external fixation in single stance pelvic fracture model. The INFIX was stiffer than external fixation for both overall axial stiffness, and stiffness at the pubic symphysis. Combined with the presumed benefit of minimizing the complications associated with external fixation, the INFIX may be a more preferable option for temporary anterior pelvic fixation in situations where external fixation may have otherwise been used.

Trauma registry record linkage: methodological approach to benefit from complementary data using the example of the German Pelvic Injury Register and the TraumaRegister DGU®

PubMed Central

2013-01-01

Background In Germany, hospitals can deliver data from patients with pelvic fractures selectively or twofold to two different trauma registries, i.e. the German Pelvic Injury Register (PIR) and the TraumaRegister DGU® (TR). Both registers are anonymous and differ in composition and content. We describe the methodological approach of linking these registries and reidentifying twofold documented patients. The aim of the approach is to create an intersection set that benefit from complementary data of each registry, respectively. Furthermore, the concordance of data entry of some clinical variables entered in both registries was evaluated. Methods PIR (4,323 patients) and TR (34,134 patients) data from 2004-2009 were linked together by using a specific match code including code of the trauma department, dates of admission and discharge, patient’s age, and sex. Data entry concordance was evaluated using haemoglobin and blood pressure levels at emergency department arrival, Injury Severity Score (ISS), and mortality. Results Altogether, 420 patients were identified as documented in both data sets. Linkage rates for the intersection set were 15.7% for PIR and 44.4% for TR. Initial fluid management for different Tile/OTA types of pelvic ring fractures and the patient’s posttraumatic course, including intensive care unit data, were now available for the PIR population. TR is benefiting from clinical use of the Tile/OTA classification and from correlation with the distinct entity “complex pelvic injury.” Data entry verification showed high concordance for the ISS and mortality, whereas initial haemoglobin and blood pressure data showed significant differences, reflecting inconsistency at the data entry level. Conclusions Individually, the PIR and the TR reflect a valid source for documenting injured patients, although the data reflect the emphasis of the particular registry. Linking the two registries enabled new insights into care of multiple-trauma patients with

Electromagnetic tracking is a relatively new technique that allows real time navigation in the absence of radiation. The aim of this study was to prove the feasibility of this technique for the treatment of posterior pelvic ring fractures and to compare the results with established image guided procedures. Tests were performed in pelvic specimens (Sawbones®) with standardized sacral fractures (Type Denis I or II). A gel matrix simulated the operative approach and a cover was used to disable visual control. The electromagnetic setup was performed by using a custom made carbon reference plate and a prototype stainless steel K-wire with an integrated sensor coil. Four different test series were performed: Group OCT: Optical navigation using preoperative CT-scans; group O3D: Optical navigation using intraoperative 3-D-fluoroscopy; group Fluoro: Conventional 2-D-fluoroscopy; group EMT: Electromagnetic navigation combined with a preoperative Dyna-CT. Accuracy of screw placement was analyzed by standardized postoperative CT-scan for each specimen. Operation time and intraoperative radiation exposure for the surgeon was documented. All data was analyzed using SPSS (Version 20, 76 Chicago, IL, USA). Statistical significance was defined as p< 0.05. 160 iliosacral screws were placed (40 per group). EMT resulted in a significantly higher incidence of optimal screw placement (EMT: 36/40) compared to the groups Fluoro (30/40; p< 0.05) and OCT (31/40; p< 0.05). Results between EMT and O3D were comparable (O3D: 37/40; n.s.). Also, the operation time was comparable between groups EMT and O3D (EMT 7.62 min vs. O3D 7.98 min; n.s.), while the surgical time was significantly shorter compared to the Fluoro group (10.69 min; p< 0.001) and the OCT group (13.3 min; p< 0.001). Electromagnetic guided iliosacral screw placement is a feasible procedure. In our experimental setup, this method was associated with improved accuracy of screw placement and shorter operation time when compared with

The treatment of high-energy open tibia fractures is challenging in both the military and civilian environments. Treatment with modern ring external fixation may reduce complications common in these patients. However, no study has rigorously compared outcomes of modern ring external fixation with commonly used internal fixation approaches. The FIXIT study is a prospective, multicenter randomized trial comparing 1-year outcomes after treatment of severe open tibial shaft fractures with modern external ring fixation versus internal fixation among men and women of ages 18-64. The primary outcome is rehospitalization for major limb complications. Secondary outcomes include infection, fracture healing, limb function, and patient-reported outcomes including physical function and pain. One-year treatment costs and patient satisfaction will be compared between the 2 groups, and the percentage of Gustilo IIIB fractures that can be salvaged without soft tissue flap among patients receiving external fixation will be estimated.

Purpose With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these sites respond to treatment similarly, then a composite fracture endpoint could provide a better estimate of hip fracture reduction. Methods Cohort study using Veterans Affairs and Medicare administrative data. Male Veterans (n=5,036,536) aged 50-99 years receiving VA primary care between1999-2009 were included. Fractures were ascertained using ICD9 and CPT codes and classified by skeletal site. Pearson correlation coefficients, logistic regression and kappa statistics, were used to describe the correlation between each fracture type and hip fracture within individuals, without regards to the timing of the events. Results 595,579 (11.8%) men suffered 1 or more fractures and 179,597 (3.6%) suffered 2 or more fractures during the time under study. Of those with one or more fractures, rib was the most common site (29%), followed by spine (22%), hip (21%) and femur (20%). The fracture types most highly correlated with hip fracture were pelvic/acetabular (Pearson correlation coefficient 0.25, p<0.0001), femur (0.15, p<0.0001), and shoulder (0.11, p<0.0001). Conclusions Pelvic, acetabular, femur, and shoulder fractures cluster with hip fractures within individuals at greater than expected frequency. If we observe similar treatment risk reductions within that cluster, subsequent trials could consider use of a composite endpoint to better estimate hip fracture risk. PMID:26151123

Purpose: To investigate pelvic insufficiency fractures (IF) after definitive pelvic radiation therapy for early-stage uterine cervical cancer, by analyzing subjects of a prospective, multi-institutional study. Materials and Methods: Between September 2004 and July 2007, 59 eligible patients were analyzed. The median age was 73 years (range, 37-84 years). The International Federation of Gynecologic Oncology and Obstetrics stages were Ib1 in 35, IIa in 12, and IIb in 12 patients. Patients were treated with the constant method, which consisted of whole-pelvic external-beam radiation therapy of 50 Gy/25 fractions and high-dose-rate intracavitary brachytherapy of 24 Gy/4 fractions without chemotherapy. After radiation therapymore » the patients were evaluated by both pelvic CT and pelvic MRI at 3, 6, 12, 18, and 24 months. Diagnosis of IF was made when the patients had both CT and MRI findings, neither recurrent tumor lesions nor traumatic histories. The CT findings of IF were defined as fracture lines or sclerotic linear changes in the bones, and MRI findings of IF were defined as signal intensity changes in the bones, both on T1- and T2-weighted images. Results: The median follow-up was 24 months. The 2-year pelvic IF cumulative occurrence rate was 36.9% (21 patients). Using Common Terminology Criteria for Adverse Events version 3.0, grade 1, 2, and 3 IF were seen in 12 (21%), 6 (10%), and 3 patients (5%), respectively. Sixteen patients had multiple fractures, so IF were identified at 44 sites. The pelvic IF were frequently seen at the sacroileal joints (32 sites, 72%). Nine patients complained of pain. All patients' pains were palliated by rest or non-narcotic analgesic drugs. Higher age (>70 years) and low body weight (<50 kg) were thought to be risk factors for pelvic IF (P=.007 and P=.013, Cox hazard test). Conclusions: Cervical cancer patients with higher age and low body weight may be at some risk for the development of pelvic IF after pelvic radiation therapy.« less

Based on a theoretical framework and sound evidence, this article describes a rehabilitation programme for patients with fear of falling after hip and pelvic fracture. Based on exercise science principles, current knowledge from fall prevention, emotion regulation, and the Health Action Process Approach we developed a theoretical framework, from which the components of the intervention were derived. Description of the intervention: The intervention consists of 6 components: (1) relaxation, (2) meaningful activities and mobility-based goals, (3) falls related cognitions and emotions, coping with high risk tasks and situations, (4) individual exercise programme, (5) planning and implementing exercises and activities, and (6) fall risks and hazards. The intervention comprises of 8 individual sessions during 3 to 5 weeks of inpatient rehabilitation and 4 telephone calls and 1 home visit over a 2-month post-discharge period. Each session or telephone call takes about 30-60 minutes. It is provided to geriatric hip and pelvic fracture patients with concerns about falling and no cognitive impairment. To ensure completeness of reporting, the Template for Intervention Description and Replication (TIDierR) is used. Fifty-seven patients were assigned to the intervention group. All 46 completers met all pre-defined criteria for an intervention per protocol. The programme is feasible to administer. We have completed a randomised controlled trial, which will be submitted in due time (for trial protocol: www.isrctn.org ; ISRCTN79191813).

Morel-Lavallée lesions are posttraumatic hemolymphatic collections caused by disruption of the interfascial planes between the subcutaneous soft tissue and muscle. Severe peripelvic Morel-Lavallée lesions have rarely been reported in the literature. By contrast, a number of cases of gluteal muscle necrosis following transcatheter angiographic embolization for pelvic fracture have been reported. Each entity can result in severe infection and sepsis, and the mortality rate in such cases is quite high. However, to date, no previous reports have described a case in which these life-threatening entities occurred simultaneously. A 32-year-old Asian man simultaneously developed severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis with sepsis following transcatheter angiographic embolization after an unstable pelvic fracture. Extremely large skin and soft tissue defects, which were untreatable with any commonly used flaps, were generated after repeated debridement. In addition, a deep-bone infection was suspected in his left fractured iliac bone, while motor function was almost completely lost in his left leg, possibly as a sequela of transcatheter angiographic embolization. As a result of his condition, a left hemipelvectomy was unavoidable. A pedicled fillet flap from his sacrificed left limb was used for the treatment of the defects and to provide a durable base for a prosthesis. Our patient survived and returned to his previous job 24 months after the surgery wearing a prosthetic left leg. As illustrated by the present case, severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis following transcatheter angiographic embolization can occur simultaneously after unstable pelvic fractures. Physicians should recognize that these entities can result in life-threatening sepsis and, therefore, should attempt to detect them as early as possible. When hemipelvectomy is unavoidable, a pedicled upper and lower leg in-continuity fillet flap may

Indications for removing orthopedic hardware on an elective basis varies widely. Although viewed as a relatively benign procedure, there is a lack of data regarding overall complication rates after fracture fixation. The purpose of this study is to determine the overall short-term complication rate for elective removal of orthopedic hardware after fracture fixation and to identify associated risk factors. Adult patients indicated for elective hardware removal after fracture fixation between July 2012 and July 2016 were screened for inclusion. Inclusion criteria included patients with hardware related pain and/or impaired cosmesis with complete medical and radiographic records and at least 3-month follow-up. Exclusion criteria were those patients indicated for hardware removal for a diagnosis of malunion, non-union, and/or infection. Data collected included patient age, gender, anatomic location of hardware removed, body mass index, ASA score, and comorbidities. Overall complications, as well as complications requiring revision surgery were recorded. Statistical analysis was performed with SPSS 20.0, and included univariate and multivariate regression analysis. 391 patients (418 procedures) were included for analysis. Overall complication rates were 8.4%, with a 3.6% revision surgery rate. Univariate regression analysis revealed that patients who had liver disease were at significant risk for complication (p=0.001) and revision surgery (p=0.036). Multivariate regression analysis showed that: 1) patients who had liver disease were at significant risk of overall complication (p=0.001) and revision surgery (p=0.039); 2) Removal of hardware following fixation for a pilon had significantly increased risk for complication (p=0.012), but not revision surgery (p=0.43); and 3) Removal of hardware for pelvic fixation had a significantly increased risk for revision surgery (p=0.017). Removal of hardware following fracture fixation is not a risk-free procedure. Patients with

Pelvic discontinuity is a rare but serious problem in orthopedic surgery. Acetabular reconstruction in case of severe bone loss after failed total hip arthroplasty is technically difficult, especially in segmental loss type III (anterior or posterior) or pelvic discontinuity (type IV). Acetabular reinforcement devices are frequently used as load-sharing devices to allow allograft incorporation and in order to serve as support of acetabular implants. This study tries to show, by means of biomechanic work, the efficiency of reinforced plate in anterior column in a segmental pelvic loss, illustrated with a clinical case, which shows the socket stability of hip prosthesis. © 2017 Elsevier Ltd.

2014-01-01

The most problematic hydrocarbons in hydraulic fracturing (fracking) wastewaters consist of fused, isolated, bridged, and spiro ring systems, and ring systems have been poorly studied with respect to biodegradation, prompting the testing here of six major ring structural subclasses using a well-characterized bacterium and a silica encapsulation system previously shown to enhance biodegradation. The direct biological oxygenation of spiro ring compounds was demonstrated here. These and other hydrocarbon ring compounds have previously been shown to be present in flow-back waters and waters produced from hydraulic fracturing operations. Pseudomonas sp. strain NCIB 9816-4, containing naphthalene dioxygenase, was selected for its broad substrate specificity, and it was demonstrated here to oxidize fundamental ring structures that are common in shale-derived waters but not previously investigated with this or related enzymes. Pseudomonas sp. NCIB 9816-4 was tested here in the presence of a silica encasement, a protocol that has previously been shown to protect bacteria against the extremes of salinity present in fracking wastewaters. These studies demonstrate the degradation of highly hydrophobic compounds by a silica-encapsulated model bacterium, demonstrate what it may not degrade, and contribute to knowledge of the full range of hydrocarbon ring compounds that can be oxidized using Pseudomonas sp. NCIB 9816-4. PMID:24907321

Immediate angiography is warranted in pelvic trauma patients with suspected arterial injury (AI) in order to stop ongoing bleeding. Prior to angiography, plain pelvic radiography (PPR) and abdominopelvic computer tomography (CT) are performed to identify fracture and hematoma sites. To investigate if PPR and CT can identify the location of AI in trauma patients undergoing angiography. 95 patients with pelvic fractures on PPR (29 women, 66 men), at a mean age of 44 (9-92) years, underwent pelvic angiography for suspected AI. Fifty-six of them underwent CT additionally. Right and left anterior and posterior fractures on PPR were registered, and fracture displacement was recorded for each quadrant. Arterial blush on CT was registered, and the size of the hematoma in each region was measured in cm(2). AIs were registered for anterior and posterior segments of both internal iliac arteries. Presence of fractures, arterial blush, and hematomas were correlated with AI. Presence of fracture in the corresponding skeletal segment on PPR showed sensitivity and specificity of 0.86 and 0.58 posteriorly, and 0.87 and 0.44 anteriorly. The area under the curve (AUC) was 0.77 and 0.69, respectively. Fracture displacement on PPR >0.9 cm posteriorly and >1.9 cm anteriorly revealed specificity of 0.84. Sensitivities of arterial blush and hematoma on CT were 0.38 and 0.82 posteriorly, and 0.24 and 0.82 anteriorly. The specificities were 0.96 and 0.58 posteriorly, and 0.79 and 0.53 anteriorly, respectively. For hematomas, the AUC was 0.79 posteriorly and 0.75 anteriorly. Size of hematoma >22 cm(2) posteriorly and >29 cm(2) anteriorly revealed specificity of 0.85 and 0.86, respectively. CT findings of arterial blush and hematoma predicted site of arterial bleeding on pelvic angiography. Also, PPR predicted the site of bleeding using location of fracture and size of displacement. In the hemodynamically unstable patient, PPR may contribute equally to effective assessment of injured arteries.

In a consensus process with four sessions in 2017, the working group "upper cervical spine" of the German Society for Orthopaedics and Trauma Surgery (DGOU) formulated "Therapeutic Recommendations for the Diagnosis and Treatment of Upper Cervical Fractures", taking their own experience and the current literature into consideration. The following article describes the recommendations for axis ring fractures (traumatic spondylolysis C2). About 19 to 49% of all cervical spine injuries include the axis vertebra. Traumatic spondylolysis of C2 may include potential discoligamentous instability C2/3. The primary aim of the diagnostic process is to detect the injury and to determine potential disco-ligamentous instability C2/3. For classification purposes, the Josten classification or the modified Effendi classification may be used. The Canadian C-spine rule is recommended for clinical screening for C-spine injuries. CT is the preferred imaging modality and an MRI is needed to determine the integrity of the discoligamentous complex C2/3. Conservative treatment is appropriate in case of stable fractures with intact C2/3 motion segment (Josten type 2 and 2). Patients should be closely monitored, in order to detect secondary dislocation as early as possible. Surgical treatment is recommended in cases of primary severe fracture dislocation or discoligamentous instability C2/3 (Josten 3 and 4) and/or secondary fracture dislocation. Anterior cervical decompression and fusion (ACDF) C2/3 is the treatment of choice. However, in case of facet joint luxation C2/3 with looked facet (Josten 4), a primary posterior approach may be necessary. Georg Thieme Verlag KG Stuttgart · New York.

Development of indirect ring tension test for fracture characterization of asphalt mixtures

NASA Astrophysics Data System (ADS)

Zeinali Siavashani, Alireza

Low temperature cracking is a major distress in asphalt pavements. Several test configurations have been introduced to characterize the fracture properties of hot mix (HMA); however, most are considered to be research tools due to the complexity of the test methods or equipment. This dissertation describes the development of the indirect ring tension (IRT) fracture test for HMA, which was designed to be an effective and user-friendly test that could be deployed at the Department of Transportation level. The primary advantages of this innovative and yet practical test include: relatively large fracture surface test zone, simplicity of the specimen geometry, widespread availability of the required test equipment, and ability to test laboratory compacted specimens as well as field cores. Numerical modeling was utilized to calibrate the stress intensity factor formula of the IRT fracture test for various specimen dimensions. The results of this extensive analysis were encapsulated in a single equation. To develop the test procedure, a laboratory study was conducted to determine the optimal test parameters for HMA material. An experimental plan was then developed to evaluate the capability of the test in capturing the variations in the mix properties, asphalt pavement density, asphalt material aging, and test temperature. Five plant-produced HMA mixtures were used in this extensive study, and the results revealed that the IRT fracture test is highly repeatable, and capable of capturing the variations in the fracture properties of HMA. Furthermore, an analytical model was developed based on the viscoelastic properties of HMA to estimate the maximum allowable crack size for the pavements in the experimental study. This analysis indicated that the low-temperature cracking potential of the asphalt mixtures is highly sensitive to the fracture toughness and brittleness of the HMA material. Additionally, the IRT fracture test data seemed to correlate well with the data from

To compare primary urethral realignment (PR) with suprapubic cystostomy (SPC) for the management of pelvic fracture-associated posterior urethral injuries with regards to rates of stricture, erectile dysfunction, and urinary incontinence. Two electronic databases (MEDLINE and EMBASE) were searched with the assistance of a librarian. Title, abstract, and full text screening was carried out by 2 independent reviewers, with discrepancies resolved by consensus. Narrative reviews, surveys, and historical articles were excluded. Only studies reporting a direct comparison of PR vs SPC for the management of posterior urethral injuries associated with blunt trauma in adults were included. Quality assessment of the included articles was performed in duplicate. Stricture incidence was evaluated for all included studies, as were erectile dysfunction and incontinence rates when reported. All outcomes were treated as dichotomous data with calculation of odds ratio and were pooled using a random effects model with Review Manager 5.1. Our comprehensive search yielded 161 unique articles. Nine articles were included in the final meta-analysis. Stricture rate was significantly lower in the PR group (odds ratio [OR] = 0.12, 95% confidence interval [CI] 0.04-0.41, P <.001). There was no significant difference between the 2 interventions with regards to erectile dysfunction (OR = 1.19, 95% CI 0.73-1.92, P = .49) or incontinence (OR = 0.75, 95% CI 0.38-1.48, P = .41). PR appears to reduce the incidence of stricture formation after pelvic fracture-associated posterior urethral injuries as compared with SPC. Copyright © 2014 Elsevier Inc. All rights reserved.

To describe the emergency and delayed treatment of patients with pelvic fracture urethral injuries (PFUI) presenting to an Italian high-volume centre. In a retrospective, observational study we evaluated the spectrum of PFUI and posterior urethroplasty in an Italian high-volume centre, from 1980 to 2013. Patients requiring emergency treatment for PFUI and delayed treatment for pelvic fracture urethral defects (PFUD) were included. Patients with incomplete clinical records were excluded from the study. Descriptive statistical methods were applied. In all, 159 male patients (median age 35 years) were included in the study. A traffic accident was the most frequent (42.8%) cause of PFUI, and accidents at work were reported as the cause of trauma in 34% of patients. Agricultural accidents decreased from 24.4% to 6.2% over the course of the survey. A suprapubic cystostomy was the most frequent (49%) emergency treatment in patients with PFUI. The use of surgical realignment decreased from 31.7% to 6.2%, and endoscopic realignment increased from 9.7% to 35.3%. A bulbo-prostatic anastomosis was the most frequent (62.9%) delayed treatment in patients with PFUD. The use of the Badenoch pull-through decreased from 19.5% to 2.6%, and endoscopic holmium laser urethrotomy increased from 4.9% to 32.7%. The spectrum of PFUI and subsequent treatment of PFUD has changed greatly over the last 10 years at our centre. These changes involved patient age, aetiology, emergency and delayed treatments, and were found to be related to changes in the economy and lifestyle of the Italian patients.

To evaluate the results of nocturnal penile erection test and response to daily sildenafil in patients with erectile dysfunction (ED) due to pelvic fracture urethral disruption. From January 2010 to January 2012, we included 38 patients with ED due to pelvic fracture urethral disruption. The mean age was 33.1 years (range, 22-49 years). All were evaluated subjectively and objectively by the International Index of Erectile Function-5, nocturnal penile tumescence and rigidity (NPTR) test, and penile Doppler ultrasonography. Patients received daily sildenafil 50 mg for 3 months. Thirty-one patients were followed up: 54.8% showed response to sildenafil defined as reporting successful vaginal penetration and intercourse. Patients with neurogenic, arterial, and venous EDs did not differ in efficiency rates (P = .587). However, the penile erectile rigidity recorded by NPTR test affected efficiency significantly (P = .046). Patients with tip rigidity >40% had the highest response rate (76.9%), but the response rate for patients with tip rigidity <20% was only 22.2%. NPTR recording can reveal resident erectile function in patients with ED due to trauma and is significant for selecting pharmacologic treatment as optimal therapy. Copyright © 2014 Elsevier Inc.

Lasting disability and further falls are common and costly problems in older people following fall-related lower limb and pelvic fractures. Exercise interventions can improve mobility after fracture and reduce falls in older people, however the optimal approach to rehabilitation after fall-related lower limb and pelvic fracture is unclear. This randomised controlled trial aims to evaluate the effects of an exercise and fall prevention self-management intervention on mobility-related disability and falls in older people following fall-related lower limb or pelvic fracture. Cost-effectiveness of the intervention will also be investigated. A randomised controlled trial with concealed allocation, assessor blinding for physical performance tests and intention-to-treat analysis will be conducted. Three hundred and fifty people aged 60 years and over with a fall-related lower limb or pelvic fracture, who are living at home or in a low care residential aged care facility and have completed active rehabilitation, will be recruited. Participants will be randomised to receive a 12-month intervention or usual care. The intervention group will receive ten home visits from a physiotherapist to prescribe an individualised exercise program with motivational interviewing, plus fall prevention education through individualised advice from the physiotherapist or attendance at the group based "Stepping On" program (seven two-hour group sessions). Participants will be followed for a 12-month period. Primary outcome measures will be mobility-related disability and falls. Secondary outcomes will include measures of balance and mobility, falls risk, physical activity, walking aid use, frailty, pain, nutrition, falls efficacy, mood, positive and negative affect, quality of life, assistance required, hospital readmission, and health-system and community-service contact. This study will determine the effect and cost-effectiveness of this exercise self management intervention on mobility

Few studies have described incidences of proximal limb and pelvic fracture (PLPF) in Thoroughbred racehorses occurring on race day and during training. Information regarding clinical presentations and future racing careers in cases of PLPF is limited. To describe the incidence, clinical presentation and outcome of PLPF sustained by horses in racing and training at the Hong Kong Jockey Club (HKJC) between 2003 and 2014. Retrospective cohort study. Horses with PLPF confirmed by nuclear scintigraphy, ultrasonography, radiography or post-mortem examination were identified using veterinary clinical records. Training and racing data for case horses were described. Incidences of fractures were estimated per 1000 horses in training and per 1000 race starts for fractures sustained during racing. Descriptive statistics were used to describe the study population. A total of 129 instances of PLPF were sustained by 108 racehorses. The most commonly fractured bone was the humerus (49.6%), followed by the tibia (29.4%). Nine horses sustained fatal fractures, eight of which occurred during racing. The incidence of fracture during racing was 0.30 per 1000 starts. Two-thirds of fractures occurred during training. The majority of horses presented with grade 3 lameness (n = 42 of 119 injury events, 35.3%). All horses presenting with grade 5 lameness sustained fatal injuries. Following noncatastrophic injury, all horses underwent box rest and 81 horses subsequently resumed racing; 45 of these won a race. Horses were retired at a median of 25 months (interquartile range: 15-36 months) after injury. Protocols for resting non-training racehorses at the HKJC and for recording rehabilitation regimens post-injury prevented the calculation of horse days at risk. The incidence of PLPF at the HKJC is low. Non-fatal PLPF is not necessarily a career-ending injury and many horses resume racing successfully following conservative treatment. © 2017 EVJ Ltd.

To investigate the clinical and radiologic outcomes in elderly patients suffering from an acetabular fracture operated with an acute primary acetabular reinforcement ring, autologous bone graft, and a total hip arthroplasty (THA). Prospective cohort study. Tertiary care university hospital. Fifteen elderly patients (7 women) with a mean age of 76 years and a displaced acetabular fracture after a low-energy trauma were included. The fractures involved the anterior column, but no patients with associated both column fractures were included. All the patients were able to walk independently before the fracture occurred. Primary operation with a Burch-Schneider reinforcement ring, autologous bone graft, and a THA. The patients were reviewed at 4, 12, 24, and 48 months after the fracture occurred. The outcome assessments included complications, reoperations, activity of daily living function, functional scores (Harris hip score and short musculoskeletal function assessment), health-related quality of life [EuroQol (EQ-5D) index score], and radiologic evaluation. There were no prosthetic dislocations, periprosthetic fractures, deep infections, or other adverse events. There were no radiologic signs of loosening of the reinforcement ring or the prosthesis components at any of the follow up sessions, and the autologous bone graft was well incorporated in all the patients at the final follow-up. At 48 months, the mean Harris hip score was 88, the mean short musculoskeletal function assessment dysfunction score was 30, the bother score was 25, and the mean EQ-5D index score was 0.65. All the patients were able to walk independently at the final follow-up. Treatment of displaced anterior column, anterior column posterior hemitransverse and transverse acetabular fractures in elderly patients using a primary reinforcement ring, autologous bone graft, and a THA seems to be a safe option with good functional and radiologic outcomes.

This study investigates the biomechanical stability of a novel technique for symphyseal internal rod fixation (SYMFIX) using a multiaxial spinal screw-rod implant that allows for direct reduction and can be performed percutaneously and compares it to standard internal plate fixation of the symphysis. Standard plate fixation (PLATE, n = 6) and the SYMFIX (n = 6) were tested on pelvic composite models with a simulated open book injury using a universal testing machine. On a previously described testing setup, 500 consecutive cyclic loadings were applied with sinusoidal resulting forces of 200 N. Displacement under loading was measured using an optoelectronic camera system and construct rigidity was calculated as a function of load and displacement. The rigidity of the PLATE construct was 122.8 N/mm (95 % CI: 110.7-134.8), rigidity of the SYMFIX construct 119.3 N/mm (95 % CI: 105.8-132.7). Displacement in the symphyseal area was mean 0.007 mm (95 % CI: 0.003-0.012) in the PLATE group and 0.021 mm (95 % CI: 0.011-0.031) in the SYMFIX group. Displacement in the sacroiliac joint area was mean 0.156 mm (95 % CI: 0.051-0.261) in the PLATE group and 0.120 mm (95 % CI: 0.039-0.201) in the SYMFIX group. In comparison to standard internal plate fixation for the stabilization of open book pelvic ring injuries, symphyseal internal rod fixation using a multiaxial spinal screw-rod implant in vitro shows a similar rigidity and comparable low degrees of displacement.

The case against primary endoscopic realignment of pelvic fracture urethral injuries

Objectives To review previous reports and present our experience on the outcomes after treating pelvic fracture urethral injuries (PFUIs) with primary endoscopic realignment (PER) vs. placing a suprapubic tube (SPT) with elective bulbomembranous anastomotic urethroplasty (BMAU). Methods We reviewed previous reports and identified articles that reported outcomes after PER vs. SPT and elective BMAU for patients who sustained PFUIs. We also present our institutional experience of treating patients who were referred after undergoing either form of treatment. Results The success rates for PER after PFUI are wide-ranging (11–86%), with variable definitions for a successful outcome. At our institution, for patients treated by SPT/BMAU, the mean time to a definitive resolution of stenosis was dramatically shorter (6 months, range 3–15) than for those treated with PER (122 months, range 4–574; P < 0.01). The vast majority of patients treated by PER required multiple endoscopic urethral interventions (median 4, range 1–36;P < 0.01) and/or had various other adverse events that were rare among the SPT/BMAU group (14/17, 82%, vs. 2/23, 9%;P < 0.05). Conclusion While PER occasionally results in urethral patency with no need for further intervention, the risk of delay in definitive treatment and the potential for adverse events have led to a preference for SPT and elective BMAU at our institution.

Pelvic and acetabular fractures are severe injuries with serious consequences that mainly happen to young people. Therefore it is highly interesting to find out to what extent affected patients succeed in returning to work, which is an important factor concerning quality of live. Thus, the objective of this study was to estimate the "return to work" in a two-year follow-up after rehabilitative treatment of patients with pelvic and acetabular fractures and to identify influencing factors. A retrospective cohort study was conducted using population-based administrative data of the Baden-Württemberg statutory pension fund. All patients (age 18 to 63 years) who had participated in a rehabilitation programme between 2004 and 2009 due to a pelvic or acetabular fracture were included. Return to work was modelled using multivariate logistic regression analysis. Rehabilitants were classified as "returned" if they have paid at least one monthly contribution due to employment during 13 to 24 months after rehabilitation. Age, gender, diagnostic group, type of rehabilitation programme, fractures of the spine, nerve injuries of the lumbosacral area and/or the lower limb and employment status before the fractures were considered as prognostic covariates. Two-thirds of the 249 researched patients returned to work. This corresponds to a reduction of employment amounting to 16.6 % for patients with a pelvic fracture and 20.8 % for patients with an acetabular fracture. Main predictor for a return to work was the employment status before the fracture. Younger patients had a better chance to return to work than older ones. Patients with fractures of the spine or nerve injuries of the lumbosacral area and/or the lower limb had a 73 % or, respectively, 78 % higher risk of not returning to work. Fractures of the pelvis and the acetabulum currently lead in one of five patients to loss of employment. Thereby the trauma threatens the social security of the young patients. Follow

The Abbreviated Injury Scale (AIS) requires the estimation of the lost blood volume for some severity assignments. This study aimed to develop a rule of thumb for facilitating AIS coding by using objective clinical parameters as surrogate markers of blood loss. Using the example of pelvic ring fractures, a retrospective analysis of TraumaRegister DGU(®) data from 2002 to 2011 was performed. As potential surrogate markers of blood loss, we recorded the hemoglobin (Hb) level, systolic blood pressure (SBP), base excess (BE), Quick's value, units of packed red blood cells (PRBCs) transfused before intensive care unit (ICU) admission, and mortality within 24 h. We identified 11,574 patients with pelvic ring fractures (Tile/OTA classification: 39 % type A, 40 % type B, 21 % type C). Type C fractures were 73.1 % AISpelvis 4 and 26.9 % AISpelvis 5. Type B fractures were 47 % AISpelvis 3, 47 % AISpelvis 4, and 6 % AISpelvis 5. In type C fractures, cut-off values of <7 g/dL Hb, <90 mmHg SBP, <-9 mmol/L BE, <35 % Quick's value, >15 units PRBCs, and death within 24 h had a positive predictive value of 47 % and a sensitivity of 62 % for AISpelvis 5. In type B fractures, these cut-off values had poor sensitivity (48 %) and positive predictive value (11 %) for AISpelvis 5. We failed to develop a rule of thumb for facilitating a proper future AIS coding using the example of pelvic ring fractures. The estimation of blood loss for severity assignment still remains a noteworthy weakness in the AIS coding of traumatic injuries.

Posterior urethra primary realignment (PUPR) after complete transection may decrease the gap between the ends of the transected urethra, tamponade the retropubic bleeding, and optimize urinary drainage without the need of suprapubic catheter facilitating concurrent pelvic orthopedic and trauma procedures. Historically, the distorted anatomy after pelvic trauma has been a major surgical challenge. The purpose of the study was to assess the relationship of the severity of the pelvic fracture to the success of endoscopic and immediate PUPR following complete posterior urethral disruption using the Young-Burgess classification system. A review of our Level I trauma center database for patients diagnosed with pelvic fracture and complete posterior urethral disruption from January 2005 to April 2012 was performed. Pelvic fracture severity was categorized according to the Young-Burgees classification system. Management consisted of suprapubic catheter insertion at diagnosis followed by early urethral realignment when the patient was clinically stable. Failure of realignment was defined as inability to achieve urethral continuity with Foley catheterization. Clinical follow-up consisted of radiologic, pressure studies and cystoscopic evaluation. A total of 481 patients with pelvic trauma from our trauma registry were screened initially, and 18 (3.7%) were diagnosed with a complete posterior urethral disruption. A total of 15 primary realignments (83.3%) were performed all within 5 days of trauma. The success rate of early realignment was 100%. There was no correlation between the type of pelvic ring fracture and the success of PUPR. Postoperatively, 8 patients (53.3%) developed urethral strictures, 3 patients (20.0%) developed incontinence, and 7 patients (46.7%) reported erectile dysfunction after the trauma. The mean follow-up of these patients was 31.8 months. Endoscopic PUPR may be an effective option for the treatment of complete posterior urethral disruption and

Urological treatment of the patient with severe mechanical trauma and urethral disruption remains controversial. Debate continues regarding the advisability of early realignment vs delayed open urethroplasty. We analyzed our experience with 96 patients to determine the long-term results of the 2 approaches. We retrospectively reviewed the records of 191 men with posterior urethral disruption after severe blunt pelvic injury between 1984 and 2001, of whom 96 survived. Data on 57 patients who underwent early realignment were compared to those on 39 treated with delayed urethroplasty with an average 8.8-year followup (range 1 to 22). All patients were evaluated postoperatively for incontinence, impotence and urethral strictures. The majority of patients had severe concomitant organ injuries (78%) and severe pelvic fractures (76%). The overall mortality rate was 51%. Diagnosis of urethral rupture was based on clinical findings and retrograde urethrography. Strictures developed in 49% of the early realignment group and in 100% of the suprapubic tube group. Impotence (33.6%) and incontinence (17.7%) were less frequent in the early realignment group than in the delayed reconstruction group (42.1% and 24.9%, respectively). Patients with delayed reconstruction underwent an average of 3.1 procedures compared with an average of 1.6 in the early realignment group. Early realignment may provide better outcomes than delayed open urethroplasty after posterior urethral disruption. Increased complications are not seen and, although it can be inconvenient in the massively injured patient, it appears to be a worthwhile maneuver.

Comparison between laparotomy first versus angiographic embolization first in patients with pelvic fracture and hemoperitoneum: a nationwide observational study from the Japan Trauma Data Bank

PubMed Central

2013-01-01

Background A common dilemma in the management of pelvic fractures is recognizing the presence of associated abdominal injury. The purpose of this study was to determine the association between initial therapeutic intervention (laparotomy or transcatheter arterial embolization (TAE)) and mortality. Methods This was a cohort study using the Japan Trauma Data Bank between 2004 and 2010, including blunt trauma patients with pelvic fractures and positive Focused Assessment with Sonography in Trauma (FAST) results. Eligible patients were restricted to those who underwent laparotomy or TAE/angiography as the initial therapeutic intervention. Crude and adjusted odds ratio (AOR) for in-hospital mortality were compared between the laparotomy first and TAE first groups (reference group). Multiple logistic regression analysis and propensity score adjusted analysis were used to adjust for clinically relevant confounders, including the severity of injury. Results Of the 317 participants, 123 patients underwent laparotomy first and 194 patients underwent TAE first. The two groups were similar in terms of age, although the laparotomy first group had higher mean Injury Severity Scores (ISS) and higher mean scores based on the abdominal Abbreviated Injury Scale (AIS), as well as lower mean pelvic AIS and systolic blood pressure (SBP). Half of the patients who were hypotensive (SBP < 90 mmHg) on arrival underwent TAE first. The laparotomy first group had a significantly higher crude in-hospital mortality (41% vs. 27%; P < 0.01). After adjusting for confounders, the choice of initial therapeutic intervention did not affect the in-hospital mortality (AOR, 1.20; 95% Confidence Interval (CI), 0.61-2.39). Even in the limited subgroup of hypotensive patients (SBP 66–89 mmHg and SBP < 65 mmHg subgroup), the effect was similar (AOR, 1.50; 95% CI, 0.56-4.05 and AOR, 1.05; 95% CI, 0.44-3.03). Conclusions In Japan, laparotomy and TAE are equally chosen as the initial

Ultrasonography has gained increased utility to diagnose pelvic fractures in horses; however, internal pelvic contours can be difficult to appreciate from external palpable landmarks. We developed three-dimensional (3D) simulations of the pelvic ultrasonographic examination to assist with translation of pelvic contours into two-dimensional (2D) images. Contiguous 1mm transverse computed tomography (CT) images were acquired through an equine femur and hemipelvis using a single slice helical scanner. 3D surface models were created using a DICOM reader and imported into a 3D modeling and animation program. The bone models were combined with a purchased 3D horse model and the skin made translucent to visualize pelvic surface contours. 3D models of ultrasound transducers were made from reference photos, and a thin sector shape was created to depict the ultrasound beam. Ultrasonographic examinations were simulated by moving transducers on the skin surface and rectally to produce images of pelvic structures. Camera angles were manipulated to best illustrate the transducer-beam-bone interface. Fractures were created in multiple configurations. Animations were exported as QuickTime movie files for use in presentations coupled with corresponding ultrasound videoclips. 3D models provide a link between ultrasonographic technique and image generation by depicting the interaction of the transducer, ultrasound beam, and structure of interest. The horse model was important to facilitate understanding of the location of pelvic structures relative to the skin surface. While CT acquisition time was brief, manipulation within the 3D software program was time intensive. Results were worthwhile from an instructional standpoint based on user feedback. © 2011 Veterinary Radiology & Ultrasound.

Purpose: Sacral insufficiency (SI) fractures can occur as a late side effect of pelvic radiation therapy. Our goal was to determine the incidence, risk factors, and clinical course of SI fractures in patients treated with preoperative chemoradiation for rectal cancer. Materials and Methods: Between 1989 and 2004, 562 patients with non-metastatic rectal adenocarcinoma were treated with preoperative chemoradiation followed by mesorectal excision. The median radiotherapy dose was 45 Gy. The hospital records and radiology reports of these patients were reviewed to identify those with pelvic fractures. Radiology images of patients with pelvic fractures were then reviewed to identify those withmore » SI fractures. Results: Among the 562 patients, 15 had SI fractures. The 3-year actuarial rate of SI fractures was 3.1%. The median time to SI fractures was 17 months (range, 2-34 months). The risk of SI fractures was significantly higher in women compared to men (5.8% vs. 1.6%, p = 0.014), and in whites compared with non-whites (4% vs. 0%, p = 0.037). On multivariate analysis, gender independently predicted for the risk of SI fractures (hazard ratio, 3.25; p = 0.031). Documentation about the presence or absence of pain was available for 13 patients; of these 7 (54%) had symptoms requiring pain medications. The median duration of pain was 22 months. No patient required hospitalization or invasive intervention for pain control. Conclusions: SI fractures were uncommon in patients treated with preoperative chemoradiation for rectal cancer. The risk of SI fractures was significantly higher in women. Most cases of SI fractures can be managed conservatively with pain medications.« less

U-shaped sacral fractures usually result from axial loading of the spine with simultaneous sacral pivoting due to a horizontal fracture which leads to a highly unstable spino-pelvic dissociation. Due to the rarity of these fractures, there is lack of an agreed treatment strategy. A thorough literature search was carried out to identify current treatment concepts. The studies were analysed for mechanism of injury, diagnostic imaging, associated injuries, type of surgery, follow-up times, complications, neurological, clinical and radiological outcome. Sixty-three cases were found in 12 articles. No Class I, II or III evidence was found in the literature. The most common mechanism of injury was a fall or jump from height. Pre-operative neurological deficit was noted in 50 (94.3%) out of 53 cases (not available in 10 patients). The most used surgical options were spino-pelvic fixation with or without decompression and ilio-sacral screws. Post-operative complications occurred in 24 (38.1%) patients. Average follow-up time was 18.6 months (range 2-34 months). Full neurological recovery was noted in 20 cases, partial recovery in 14 and 9 patients had no neurological recovery (5 patients were lost in follow-up). Fracture healing was mentioned in 7 articles with only 1 case of fracture reduction loss. From the current available data, an evidence based treatment strategy regarding outcome, neurological recovery or fracture healing could not be identified. Limited access and minimal-invasive surgery focussing on sacral reduction and restoration seems to offer comparable results to large spino-pelvic constructs with fewer complications and should be considered as the method of choice. If the fracture is highly unstable and displaced, spino-pelvic fixation might offer better stability.

Acetabular fractures have always been very challenging for orthopedic surgeons; therefore, appropriate preoperative evaluation and planning are particularly important. This study aimed to explore the application methods and clinical value of preoperative computer simulation (PCS) in treating pelvic and acetabular fractures. Spiral computed tomography (CT) was performed on 13 patients with pelvic and acetabular fractures, and Digital Imaging and Communications in Medicine (DICOM) data were then input into Mimics software to reconstruct three-dimensional (3D) models of actual pelvic and acetabular fractures for preoperative simulative reduction and fixation, and to simulate each surgical procedure. The times needed for virtual surgical modeling and reduction and fixation were also recorded. The average fracture-modeling time was 45 min (30-70 min), and the average time for bone reduction and fixation was 28 min (16-45 min). Among the surgical approaches planned for these 13 patients, 12 were finally adopted; 12 cases used the simulated surgical fixation, and only 1 case used a partial planned fixation method. PCS can provide accurate surgical plans and data support for actual surgeries.

In pelvic fracture operations, bone plate shaping is challenging and the operation time is long. To address this issue, a customized bone plate was designed and produced using selective laser melting (SLM) technology. The key steps of this study included designing the customized bone plate, metal 3D printing, vacuum heat treatment, surface post-processing, operation rehearsal, and clinical application and evaluation. The joint surface of the bone plate was placed upwards with respect to the build platform to keep it away from the support and to improve the quality of the joint surface. Heat conduction was enhanced by adding a cone-type support beneath the bone plate to prevent low-quality fabrication due to poor heat conductivity of the Ti-6Al-4V powder. The residual stress was eliminated by exposing the SLM-fabricated titanium-alloy bone plate to a vacuum heat treatment. Results indicated that the bone plate has a hardness of HV1 360-HV1 390, an ultimate tensile strength of 1000-1100 MPa, yield strength of 900-950 MPa, and an elongation of 8%-10%. Pre-operative experiments and operation rehearsal were performed using the customized bone plate and the ABC-made pelvic model. Finally, the customized bone plate was clinically applied. The intraoperative C-arm and postoperative X-ray imaging results indicated that the customized bone plate matched well to the damaged pelvis. The customized bone plate fixed the broken bone and guides pelvis restoration while reducing operation time to about two hours. The customized bone plate eliminated the need for preoperative titanium plate pre-bending, thereby greatly reducing surgical wounds and operation time.

Stress fractures occur following excessive use and are commonly seen in athletes, in whom the lower limbs are frequently involved. Delayed diagnosis and management of these injuries can result in significant long-term damage and athlete morbidity. A high index of suspicion may facilitate diagnosis, but clinical presentation may be non-specific. In this regard, imaging in the form of plain radiograph, CT, MRI and bone scintigraphy may be of value. This article reviews the incidence, presentation, radiological findings and management options for athletes with stress fractures of the lower limb. PMID:22815414

To compare the stability of lengthened sacroiliac screw and standard sacroiliac screw for the treatment of unilateral vertical sacral fractures; to provide reference for clinical applications. A finite element model of Tile type C pelvic ring injury (unilateral Denis type II fracture of the sacrum) was produced. The unilateral sacral fractures were fixed with lengthened sacroiliac screw and sacroiliac screw in six different types of models respectively. The translation and angle displacement of the superior surface of the sacrum (in standing position on both feet) were measured and compared. The stability of one lengthened sacroiliac screw fixation in S1 or S2 segment is superior to that of one sacroiliac screw fixation in the same sacral segment. The stability of one lengthened sacroiliac screw fixation in S1 and S2 segments respectively is superior to that of one sacroiliac screw fixation in S1 and S2 segments respectively. The stability of one lengthened sacroiliac screw fixation in S1 and S2 segments respectively is superior to that of one lengthened sacroiliac screw fixation in S1 or S2 segment. The stability of one sacroiliac screw fixation in S1 and S2 segments respectively is markedly superior to that of one sacroiliac screw fixation in S1 or S2 segment. The vertical and rotational stability of lengthened sacroiliac screw fixation and sacroiliac screw fixation in S2 is superior to that of S1. In a finite element model of type C pelvic ring disruption, S1 and S2 lengthened sacroiliac screws should be utilized for the fixation as regularly as possible and the most stable fixation is the combination of the lengthened sacroiliac screws of S1 and S2 segments. Even if lengthened sacroiliac screws cannot be systematically used due to specific conditions, one sacroiliac screw fixation in S1 and S2 segments respectively is recommended. No matter which kind of sacroiliac screw is used, if only one screw can be implanted, the fixation in S2 segment is more recommended

Penile injuries in children are usually uncommon and are predominantly associated with pelvic trauma or as postcircumcision injuries. The authors present a rare case of penile dislocation with penile inversion in a 5-year-old child occurring due to blunt pelvic injury. The child presented 3 months after pelvic injury with a suprapubic catheter for urinary diversion and absent penis with only penile skin visible. The presence of dislocated penile body was detected on magnetic resonance imaging, which was subsequently confirmed intraoperatively. During the surgery, the dislocated penis was identified and mobilized into its normal anatomical position within the remnant penile skin. Very few cases of penile dislocation have been reported in the literature. Pubic fracture with pulling of suspensory ligament resulting in dislocation of the penis would have been the probable mechanism of injury. PMID:29681700

Pregnancy-related pelvic girdle pain: an update

PubMed Central

2011-01-01

A large number of scientists from a wide range of medical and surgical disciplines have reported on the existence and characteristics of the clinical syndrome of pelvic girdle pain during or after pregnancy. This syndrome refers to a musculoskeletal type of persistent pain localised at the anterior and/or posterior aspect of the pelvic ring. The pain may radiate across the hip joint and the thigh bones. The symptoms may begin either during the first trimester of pregnancy, at labour or even during the postpartum period. The physiological processes characterising this clinical entity remain obscure. In this review, the definition and epidemiology, as well as a proposed diagnostic algorithm and treatment options, are presented. Ongoing research is desirable to establish clear management strategies that are based on the pathophysiologic mechanisms responsible for the escalation of the syndrome's symptoms to a fraction of the population of pregnant women.

2015-01-01

To enhance the diminished screw purchase in cancellous, osteoporotic bone following the fixation of posterior pelvic ring injuries by iliosacral screws an increased bone-implant contact area using modificated screws, techniques or bone cement may become necessary. The aim of the study was to identify sites within the pathway of iliosacral screws requiring modifications of the local bone or the design of instrumentations placed at this site. The breakaway torque was measured mechanically at the iliosacral joint ("ISJ"), the sacral lateral mass ("SLM") and the center of the S1 ("CS1"), at a superior and an inferior site under fluoroscopic control on five human cadaveric specimens (3 female; mean age 87 years, range: 76-99) using the DensiProbe™Spine device. The measured median (range) breakaway torque was 0.63 Nm (0.31-2.52) at the "iliosacral joint", 0.14 Nm (0.05-1.22) at the "sacral lateral mass", 0.57 Nm (0.05-1.42) at the "S1 center." The "sacral lateral mass" breakaway torque was lower than compared to that at the "iliosacral joint" (p < .001) or "S1 center" (p < .001). The median (range) breakaway torque measured at all superior measurement points was 0.52 Nm (0.10-2.52), and 0.48 Nm (0.05-1.18) at all inferior sites. The observed difference was statistically significant (p < .05). The lateral mass of the sacrum provides the lowest bone quality for implant anchorage. Iliosacral screws should be placed as superior as safely possible, should bridge the iliosacral joint and may allow for cement application at the lateral mass of the sacrum through perforations.

The aim of our study is to solve the problem of insufficient fixation of comminuted fractures of the quadrilateral plane and the iliopectineal line. These fixation problems occur while using the standard narrow 3.5 mm fixation plate applied from a modified Stoppa approach. A new plate developed by the authors--the Omega plate--fulfils the requirements. In the period 2010-2012, we performed 156 stabilisations of pelvic ring fractures and acetabular fractures. We used the modified Stoppa approach applying the standard fixation plate in 24 patients and the Omega plate in 15 patients. The patient group with the Omega plate included 10 male and five female patients with the average age of 61 years (range, 30-72). Only 11 patients were followed up, with an average period of 13.3 months, because one patient was lost to followup and three patients were shortly after surgery. The surgical technique of Omega plate application is described in detail. The clinical evaluation of post-operative results was based on the Harris Hip Score; the graphical results were rated using the Matta and Pohlemann criteria. The Stoppa approach alone was used in four patients, combination of two approaches (Stoppa and Kocher-Langenbeck approach) was used in six cases and three approaches were employed in five patients. No adverse intra- or post-operative events were recorded. Excellent or satisfactory graphical results were obtained in 12 patients and an unsatisfactory graphical outcome was recorded in three cases. In the follow-up period ranging from 8 to 22 months, 11 patients healed. Late complications included avascular femoral head necrosis in two and severe post-traumatic coxarthrosis in three patients. Due to these complications, all five patients underwent total hip arthroplasty without previous Omega plate removal at an average interval of 15 months from the primary pelvic surgery. They were not included in the follow-up evaluation. The remaining six patients had an average Harris Hip

The purpose of our study was to evaluate minimally invasive sacroiliac screw fixation for treatment of posterior pelvic instability with the help of CT controlled guidewires, assess its accuracy, safety and effectiveness, and discuss potential pitfalls. 100 guidewires and hollow titan screws were inserted in 38 patients (49.6±19.5 years) suffering from 35 sacral fractures and/or 16 sacroiliac joint disruptions due to 33 (poly-)traumatic, 2 osteoporotic and 1 post-infectious conditions. The guidewire and screw positions were analyzed in multiplanar reconstructions. The mean minimal distance between guidewire and adjacent neural foramina was 4.5±2.01mm, with a distinctly higher precision in S1 than S2. Eight guidewires showed cortical contacts, resulting in a total of 2% mismatched screws with subsequent wall violation. The fracture gaps were reduced from 3.6±0.53mm to 1.2±0.54mm. During follow-up 3 cases of minor iatrogenic sacral impaction (<5mm) due to the bolting and 2 cases of screw loosening were observed. Interventional time was 84.0min with a mean of 2.63 screws per patient whilst acquiring a mean of 93.7 interventional CT-images (DLP 336.7mGycm). The treatment of posterior pelvic instability with a guidewire-based screw insertion technique under CT-imaging results in a very high accuracy and efficacy with a low complication rate. Careful attention should be drawn to radiation levels. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Synthetic vaginal mesh for pelvic organ prolapse.

PubMed

Iglesia, Cheryl B

2011-10-01

The purpose of this review is to summarize recently published comparative trials on synthetic vaginal mesh versus traditional native tissue repairs for pelvic organ prolapse. Although studies suggest benefit from the use of synthetic vaginal mesh for anterior compartment prolapse, data are limited on the use of mesh for posterior and apical prolapse when compared with native tissue repair. The benefits of a more durable repair must be weighed against risks such as the development of de-novo stress incontinence, visceral injury, dyspareunia, pelvic pain and mesh contraction, exposure and extrusion requiring reoperation. Furthermore, the success rates of native tissue repairs are higher than previously considered using updated validated composite outcomes that incorporate both subjective relief of bulge and objective cure defined as prolapse above the hymenal ring. Surgeons placing synthetic mesh for pelvic organ prolapse should counsel patients regarding the potential benefits, risks, and alternatives including native tissue repairs. Level 1 evidence suggests anterior synthetic mesh may be superior to anterior repair. Expert opinion suggests potential benefit of vaginal mesh for recurrences, hysteropexy, and advanced prolapse in patients with medical co-morbidities precluding invasive open and endoscopic sacrocolpopexies; however, comparative clinical trials with long-term data are needed.

Newman, C Benjamin; Keshavarzi, Sassan; Aryan, Henry E

When the management of sacral tumors requires partial or complete sacrectomy, the spinopelvic apparatus must be reconstructed. This is a challenging and infrequently performed operation, and as such, many spine surgeons are unfamiliar with techniques available to carry out these procedures. A 34-year-old man presented with severe low back pain, mild left ankle dorsiflexion weakness, and left S1 paresthesias. Imaging revealed a large sacral mass extending into the L5/S1 and S1/S2 neural foramina as well as the presacral visceral and vascular structures. Needle biopsy of this mass demonstrated a low-grade chondrosarcoma. A 2-stage anterior/posterior en bloc sacrectomy with a novel modification of the Galveston L-rod pelvic ring reconstruction was carried out. Our modification takes advantage of new materials and implant technology to offer another alternative in reconstruction of the spinopelvic junction. Understanding the anatomy and biomechanics of the spinopelvic apparatus and the lumbosacral junction, as well as having a familiarity with the various techniques available for carrying out sacrectomy and pelvic ring reconstruction, will enable the spine surgeon to effectively manage sacral tumors.

This study is aimed at definition of the safe and dangerous zone for screw placement with Stoppa approach for rapid identification during operation and a new way for the studies on the "safe zone." Pelvic CT data of 84 human subjects were recruited to reconstruct the three-dimensional (3D) models. The distances between the edges of the "safe zone," "dangerous zone," and specific anatomic landmarks such as the obturator canal and the pelvic brim were precisely measured, respectively. The results show that the absolute "dangerous zone" was from the pelvic brim to 3.07 cm below it and within 2.86 cm of the obturator canal, while the region 3.56 cm below the pelvic brim or 3.85 cm away from the obturator canal was the absolute "safe zone" for screw placement. The region between the absolute "safe zone" and the absolute "dangerous zone" was the relatively "dangerous zone." As a conclusion, application of computer-assisted 3D modeling techniques aids in the precise measurement of "safe zone" and "dangerous zone" in combination with Stoppa incision. It was not recommended to place screws on the absolute dangerous zone, while, for the relatively "dangerous zone," it depends on the individual variations in bony anatomy and the fracture type.

The three more frequent primitive malignant bone tumour which concerned the iliac bone are chondrosarcoma, following Ewing sarcoma and osteosarcoma. Wide resection remains the most important part of the treatment associated with chemotherapy for osteosarcoma and the Ewing sarcoma. Iliac wing resections and obdurate ring don't required reconstruction. However, acetabular resections and iliac wing resection with disruption of the pelvic ring required reconstruction to provide acceptable functional result. Acetabular reconstruction remains high technical demanding challenge. After isolated acetabular resection or associated to obdurate ring, our usual method of reconstruction is homolateral proximal femoral autograft and total hip prosthesis but it is possible to also used : saddle prosthesis, Mac Minn prosthesis with auto or allograft, modular prosthesis or custom made prosthesis, massive allograft with or without prosthesis and femoro-ilac arthrodesis. After resection of the iliac wing plus acetabulum, reconstruction can be performed by femoro-obturatrice and femora-sacral arthrodesis, homolateral proximal femoral autograft and prosthesis, femoral medialisation, massive allograft and massive allograft. Carcinological results are lesser than resection for distal limb tumor, local recurrence rate range 17 to 45%. Functional results after Iliac wing and obdurate ring are good. However, acetabular reconstruction provide uncertain functional results. The lesser results arrive after hemipelvic or acetabular and iliac wing resection-reconstruction, especially when gluteus muscles were also resected. The most favourable results arrive after isolated acetabular or acetabular plus obturateur ring resection-reconstruction.

The aim of this study was to investigate the sacroiliac joint injury mechanism. Two test configurations were selected from full scale car crashes conducted with the WorldSID 50 th dummy resulting in high sacroiliac joint loads and low pubic symphysis force, i.e. severe conditions for the sacroiliac joint. The two test conditions were reproduced in laboratory using a 150-155 kg guided probe propelled respectively at 8 m/s and 7.5 m/s and with different shapes and orientations for the plate impacting the pelvis. Nine Post Mortem Human Subject (PMHS) were tested in each of the two configurations (eighteen PMHS in total). In order to get information on the time of fracture, eleven strain gauges were glued on the pelvic bone of each PMHS. Results - In the first configuration, five PMHS out of nine sustained AIS2+ pelvic injuries. All five presented sacroiliac joint injuries associated with pubic area injuries. In the second configuration, four specimens out of nine sustained AIS2+ pelvic injuries. Two of them presented sacroiliac joint fractures associated with pubic area injuries. The other two presented injuries at the pubic area and acetabulum only. The strain gauges signals suggested that the pubic fractures occurred before the sacroiliac joint fractures in the great majority of the cases (five cases out of seven). Conclusions - Even in the oblique impact conditions of the present study, the pubic symphysis area was observed to be the weakest zone of the pelvis and its failure the predominant cause of sacroiliac joint injuries. It was hypothesized that the failure of the pubic rami allowed the hemi-pelvis to rotate inward, and that this closing-book motion induced the failure of the sacroiliac joint.

Our goal is to provide an update on the results of pelvic floor rehabilitation in the treatment of urinary incontinence and genital prolapse symptoms. Pelvic floor muscle training allows a reduction of urinary incontinence symptoms. Pelvic floor muscle contractions supervised by a healthcare professional allow cure in half cases of stress urinary incontinence. Viewing this contraction through biofeedback improves outcomes, but this effect could also be due by a more intensive and prolonged program with the physiotherapist. The place of electrostimulation remains unclear. The results obtained with vaginal cones are similar to pelvic floor muscle training with or without biofeedback or electrostimulation. It is not known whether pelvic floor muscle training has an effect after one year. In case of stress urinary incontinence, supervised pelvic floor muscle training avoids surgery in half of the cases at 1-year follow-up. Pelvic floor muscle training is the first-line treatment of post-partum urinary incontinence. Its preventive effect is uncertain. Pelvic floor muscle training may reduce the symptoms associated with genital prolapse. In conclusion, pelvic floor rehabilitation supervised by a physiotherapist is an effective short-term treatment to reduce the symptoms of urinary incontinence or pelvic organ prolapse.

 To investigate whether bariatric surgery increases the risk of fracture.  Retrospective nested case-control study.  Patients who underwent bariatric surgery in the province of Quebec, Canada, between 2001 and 2014, selected using healthcare administrative databases.  12 676 patients who underwent bariatric surgery, age and sex matched with 38 028 obese and 126 760 non-obese controls.  Incidence and sites of fracture in patients who had undergone bariatric surgery compared with obese and non-obese controls. Fracture risk was also compared before and after surgery (index date) within each group and by type of surgery from 2006 to 2014. Multivariate conditional Poisson regression models were adjusted for fracture history, number of comorbidities, sociomaterial deprivation, and area of residence.  Before surgery, patients undergoing bariatric surgery (9169 (72.3%) women; mean age 42 (SD 11) years) were more likely to fracture (1326; 10.5%) than were obese (3065; 8.1%) or non-obese (8329; 6.6%) controls. A mean of 4.4 years after surgery, bariatric patients were more susceptible to fracture (514; 4.1%) than were obese (1013; 2.7%) and non-obese (3008; 2.4%) controls. Postoperative adjusted fracture risk was higher in the bariatric group than in the obese (relative risk 1.38, 95% confidence interval 1.23 to 1.55) and non-obese (1.44, 1.29 to 1.59) groups. Before surgery, the risk of distal lower limb fracture was higher, upper limb fracture risk was lower, and risk of clinical spine, hip, femur, or pelvic fractures was similar in the bariatric and obese groups compared with the non-obese group. After surgery, risk of distal lower limb fracture decreased (relative risk 0.66, 0.56 to 0.78), whereas risk of upper limb (1.64, 1.40 to 1.93), clinical spine (1.78, 1.08 to 2.93), pelvic, hip, or femur (2.52, 1.78 to 3.59) fractures increased. The increase in risk of fracture reached significance only for biliopancreatic diversion.  Patients undergoing bariatric

The long-term outcomes following complex fractures of the tibia are reported to carry a risk of knee pain, malalignment, articular injury and post-traumatic osteoarthritis. The main objective of this study was to account for the patient-reported quality of life (QOL) 12 months after ring fixator removal in patients with a complex tibial fracture. Secondary objectives included a review of the socio-economic characteristics of the patient group and the rate of return to work in the study period. A prospective follow-up study was conducted of 60 patients with complex fractures of the tibia treated with ring external fixation. Patient-reported outcomes, radiological outcomes and socio-economic status including employment status of the patients were obtained 12 months after frame removal. Forty-six patients completed the assessment 12 months after frame removal (77%). The mean age of the patient at the time of fracture was 54.6 years (range 31-86). There were 19 males and 27 females. At 12 months after frame removal, the mean EQ5D-5L index was 0.66 (CI 0.60-0.72). The mean EQ5D-5L VAS was 69 (CI 61-76). When this was compared to the established reference population from Denmark, the study population showed a significantly worse EQ5D-5L index. The majority of patients (87%) were in the lower social classes suggesting a higher degree of social deprivation in the study population. Twenty-seven per cent of patients who were employed prior to injury had returned to employment at approximately 19 months following fracture. The onset of post-traumatic osteoarthritis was present in the knee joint in 29% of patients following a proximal intra-articular fracture, whereas osteoarthritis was present at the ankle joint in 35% of patients following a distal intra-articular fracture 12 months after frame removal. This study indicates that at 12 months after frame removal there are poorer patient-reported QOL as when compared to reference populations. Furthermore, this study

Total sacrectomy with spinal-pelvic fixation is considered to be a successful approach to the radical surgical treatment of extensive sacral tumors, however, technically very demanding, thus only rarely reported in the literature. We presented a patient with sacral gigantocellular tumor managed successfully using this method but with certain standard operative techniques improvements. A 30-year old patient with a pronounced painful syndrome and sphincter disorders was confirmed to have sacral gigantocellular tumor affecting a greater part of the sacrum. Tumor resection was performed in the first act out off retroperitoneal organs (colon and blood vessels), sacroiliac joints were open by the ventral side, the L5 discus removed, the S2-S5 roots cut off. In the second act, performed three weeks later, sacrectomy was completed by the reconstruction of pelvic ring and spinal-pelvic fixation. Then, the standard technique was modified to provide additional spinal fixation. The results of the operation (duration, blood loss, postoperative deficit) were quite comparable with, and in some aspects even better than the results published in the literature. Total sacrectomy with spinal-pelvic fixation can be a therapy of choice in patients with extensive sacral tumors requaring, however, the multidisciplinary approach and a considerable experience with instrumental spinal stabilization.

Pelvic tilt (PT) is used as an indicator of pelvic version with increased values indicating retroversion and disability. The concept of using PT solely as an absolute numerical value can be misleading, especially for the patients with pelvic incidence (PI) values near the upper and lower normal limits. Relative pelvic version (RPV) is a PI-based individualized measure of the pelvic version. Relative pelvic version indicates the individualized spatial orientation of the pelvis relative to the ideal sacral slope as defined by the magnitude of PI. The aim of this study was to compare RPV and PT for their ability to predict mechanical complications and their correlations with health-related quality of Life (HRQoL) scores. A retrospective analysis of a prospectively collected data of adult spinal deformity patients was carried out. Mechanical complications (proximal junctional kyphosis or proximal junctional failure, distal junctional kyphosis or distal junctional failure, rod breakage, and implant-related complications) and HRQoL scores (Oswestry Disability Index [ODI], Core Outcome Measures Index [COMI], Short Form-36 Physical Component Summary [SF-36 PCS], and Scoliosis Research Society 22 Spinal Deformity Questionnaire [SRS-22]) were used as outcome measures. Inclusion criteria were ≥4 levels fusion, and ≥2-year follow-up. Correlations between PT, RPV, PI, and HRQoL were analyzed using Pearson correlation coefficient. Pelvic incidence values and mechanical complication rates in RPV subgroups for each PT category were compared using one-way analysis of variance, Student t test, and chi-squared tests. Predictive models for mechanical complications with RPV and PT were analyzed using binomial logistic regressions. A total of 222 patients (168 women, 54 men) met the inclusion criteria. Mean age was 52.2±19.3 (18-84) years. Mean follow-up was 28.8±8.2 (24-62) months. There was a significant correlation between PT and PI (r=0.613, p<.001), threatening the use of PT

Digitally reconstructed radiograph-based study. Using a computer-based method to determine what degree of pelvic rotation is acceptable for measuring the pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). The effectiveness of a geometrical formula used to calculate the angle of pelvic rotation proposed in a previous article was assessed. It is unclear whether PI, PT, and SS are valid with pelvic rotation while acquiring a radiograph. Ten 3-dimensionally reconstructed models were established with software and placed in a neutral orientation to orient all of the bones in a standing position. Next, 140 digitally reconstructed radiographs were obtained by rotating the models around the longitudinal axis of each pelvis in the software from 0 to 30 degrees at 2.5-degree intervals. PI, PT, and SS were measured. The rotation angle was considered to be acceptable when the change in the measured angle (compared with the "correct" position) was <6 degrees. The rotation angle (α) on the images was calculated by a geometrical formula. Consistency between the measured value and the set angle was assessed. The acceptable maximum angle of rotation for reliable measurements of PI was 17.5 degrees, and the changes in PT and SS were within an acceptable range (<6 degrees) when the pelvic rotation increased from 0 to 30 degrees. The effectiveness of the geometrical formula was shown by the consistency between the set and the calculated rotation angles of the pelvis (intraclass correlation coefficient=0.99). Our study provides insight into the influence of pelvic rotation on the PI, PT, and SS. PI changes with pelvic rotation. The acceptable maximum angle for reliable values of PI, PT, and SS was 17.5 degrees, and the rotation angle of the pelvis on a lateral spinopelvic radiograph can be calculated reliably.

To characterize bone fractures and the usefulness of micro-CT for imaging fractures in pet rabbits. Retrospective case series. 210 client-owned rabbits with bone fractures. Medical records of rabbits evaluated for bone fractures from 2007 through 2013 were examined. Information was collected on signalment and nature of fractures, and radiographic and micro-CT images of fractures were reviewed. Almost half (n = 95 [47.7%]) of fractures were in rabbits < 3 years old. Accidental fall was the most common cause. Vertebral fracture was the most common type of fracture with a nonneoplastic cause (n = 46 [23.2%]) and was most common in the L4-L7 region. The tibia was the most common site for limb fracture among all fractures with a nonneoplastic cause (45 [22.7%]). Twelve (5.7%) fractures had a neoplastic cause, and 7 of these were associated with metastatic uterine adenocarcinoma. Females were significantly more likely to have a fracture caused by neoplasia than were males. Compared with radiography, micro-CT provided more detailed fracture information, particularly for complicated fractures or structures (eg, skull, pelvic, vertebral, and comminuted limb fractures). Findings were useful for understanding the nature of fractures in pet rabbits and supported the use of micro-CT versus radiography for fracture detection and evaluation.

Pelvic Arterial Embolisation in a Trauma Patient with a Pre-Existing Aortobifemoral Graft

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 bemore » 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.« less

To review our experience with penile revascularization for patients with bilateral occlusion of the deep internal pudendal arteries after pelvic fracture urethral injury (PFUI). We identified 17 patients who had undergone penile revascularization with end-to-side anastomosis of the deep inferior epigastric artery to the dorsal penile artery from July 1991 to December 2010. Success was defined as achieving erections sufficient for intercourse with or without pharmacologic assistance. All patients had had a PFUI causing arterial insufficiency and erectile dysfunction not responsive to pharmacologic intervention. Of the 17 patients, 4 (24%) underwent revascularization before and 13 (76%) after PFUI repair. The mean age at revascularization was 32.7 years (range 17-54). At an average follow-up of 3.1 years, the surgery was successful in 14 of the 17 patients (82%). In patients with erectile dysfunction as an indication for surgery, successful erections were achieved in 11 of 13. For those who underwent revascularization to prevent ischemic stenosis of the urethral repair, 3 of 4 achieved successful erections, and all subsequent urethral surgeries were successful. The penile duplex ultrasound parameters showed clinically and statistically significant improvements after revascularization. No operative complications developed. The average hospital length of stay was 4.7 days. Four patients experienced early postoperative complications, including an abdominal wall hematoma requiring evacuation in one, penile edema in two, and a superficial surgical site infection in one. No late complications occurred. Penile arterial revascularization in select patients can allow for successful treatment of PFUIs and the refractory erectile dysfunction caused by them.

Review of techniques for monitoring the healing fracture of bones for implementation in an internally fixated pelvis.

PubMed

Wong, Lydia Chwang Yuh; Chiu, Wing Kong; Russ, Matthias; Liew, Susan

2012-03-01

Sacral fractures from high-impact trauma often cause instability in the pelvic ring structure. Treatment is by internal fixation which clamps the fractured edges together to promote healing. Healing could take up to 12 weeks whereby patients are bedridden to avoid hindrances to the fracture from movement or weight bearing activities. Immobility can lead to muscle degradation and longer periods of rehabilitation. The ability to determine the time at which the fracture is stable enough to allow partial weight-bearing is important to reduce hospitalisation time. This review looks into different techniques used for monitoring the fracture healing of bones which could lead to possible methods for in situ and non-invasive assessment of healing fracture in a fixated pelvis. Traditional techniques being used include radiology and CT scans but were found to be unreliable at times and very subjective in addition to being non in situ. Strain gauges have proven to be very effective for accurate assessment of fracture healing as well as stability for long bones with external fixators but may not be suitable for an internally fixated pelvis. Ultrasound provides in situ monitoring of stiffness recovery but only assesses local fracture sites close to the skin surface and has only been tested on long bones. Vibration analysis can detect non-uniform healing due to its assessment of the overall structure but may suffer from low signal-to-noise ratio due to damping. Impedance techniques have been used to assess properties of non-long bones but recent studies have only been conducted on non-biological materials and more research needs to be done before it can be applicable for monitoring healing in the fixated pelvis.

Anterior sacroiliac joint plate fixation for unstable pelvic ring fractures avoids soft tissue problems in the buttocks; however, the lumbosacral nerves lie in close proximity to the sacroiliac joint and may be injured during the procedure. A 49 year-old woman with a type C pelvic ring fracture was treated with an anterior sacroiliac plate using a computed tomography (CT)-three-dimensional (3D)-fluoroscopy matching navigation system, which visualized the lumbosacral nerves as well as the iliac and sacral bones. We used a flat panel detector 3D C-arm, which made it possible to superimpose our preoperative CT-based plan on the intra-operative 3D-fluoroscopic images. No postoperative complications were noted. Intra-operative lumbosacral nerve visualization using computer navigation was useful to recognize the 'at-risk' area for nerve injury during anterior sacroiliac plate fixation.

Microstructure-Texture-Mechanical Properties in Hot Rolling of a Centrifugal Casting Ring Blank

NASA Astrophysics Data System (ADS)

Qin, Fang-cheng; Li, Yong-tang; Qi, Hui-ping; Ju, Li

2016-03-01

Deformation characteristic of centrifugal casting 25Mn steel was investigated by compression tests, and then processing maps were established. According to the deformation parameters identified from the established processing maps and hot ring rolling (HRR) process, the industrial test for the 25Mn ring blank was performed. Optical microscope (OM) and electron backscatter diffraction (EBSD) techniques were used for detecting grain boundary features and textures of deformation structures. The morphologies and mechanisms of tensile and impact fracture were revealed. The results show that softening effect plays a dominant role in higher temperatures of 1050-1150 °C and strain rates lower than 0.1 s-1. The average grain size of the rolled 25Mn ring is about 28 μm, but the grains are more coarse and inhomogeneous on the middle layer than that on rest of the areas. The texture on the outer layer is characterized by strong {110} <112> and weak {112} <111>, followed by {001} <100> and {001} <110> on the inner layer and {110} <110> on the center layer, which is mainly associated with the shear deformation. The rolled ring with precise geometrical dimensions and sound mechanical properties is fabricated by HRR. Tensile fracture is composed of clear river-shaped pattern and a little dimple near the inner layer and outer layer, and the fracture mechanism is mainly quasi-cleavage fracture, accompanied by dimple fracture. The morphologies of impact fracture consist of tear ridge and cleavage platform.

normal intrauterine pregnancy from threatened or spontaneous abortion, ectopic pregnancy and other complications that may occur in patients with positive pregnancy test. Incomplete abortion is visualized as thickened and irregular endometrial echo with certain amount of intracavitary fluid. If applied, color Doppler ultrasound reveals low vascular resistance signals in richly perfused intracavitary area. Transvaginal sonography has high sensitivity and specificity in visualization of uterine and adnexal signs of ectopic pregnancy. Color Doppler examination may aid in detection of the peritrophoblastic flow. Furthermore, it facilitates detection of ectopic living embryo, tubal ring or unspecific adnexal tumor. Corpus luteum cysts and leiomyomas are another cause of pelvic pain during pregnancy, which can be correctly diagnosed by ultrasound. Detection of uterine dehiscence and rupture in patients with history of prior surgical intervention on uterine wall relies exclusively on correct ultrasound diagnosis. In patients with placental abruption sonographer detects hypoechoic complex representing either retroplacental hematoma, subchorionic hematoma or subamniotic hemorrhage. In closing, ultrasound has already become important and easily available tool which can efficiently recognize patients with possibly threatening conditions of different origins.

Introduction. Pelvic floor dysfunction syndromes present with voiding, sexual, and anorectal disturbances, which may be associated with one another, resulting in complex presentation. Thus, an integrated diagnosis and management approach may be required. Pelvic muscle rehabilitation (PMR) is a noninvasive modality involving cognitive reeducation, modification, and retraining of the pelvic floor and associated musculature. We describe our standardized PMR protocol for the management of pelvic floor dysfunction syndromes. Pelvic Muscle Rehabilitation Program. The diagnostic assessment includes electromyography and manometry analyzed in 4 phases: (1) initial baseline phase; (2) rapid contraction phase; (3) tonic contraction and endurance phase; and (4) late baseline phase. This evaluation is performed at the onset of every session. PMR management consists of 6 possible therapeutic modalities, employed depending on the diagnostic evaluation: (1) down-training; (2) accessory muscle isolation; (3) discrimination training; (4) muscle strengthening; (5) endurance training; and (6) electrical stimulation. Eight to ten sessions are performed at one-week intervals with integration of home exercises and lifestyle modifications. Conclusions. The PMR protocol offers a standardized approach to diagnose and manage pelvic floor dysfunction syndromes with potential advantages over traditional biofeedback, involving additional interventions and a continuous pelvic floor assessment with management modifications over the clinical course.

Pelvic floor muscles have potential to influence relative pelvic alignment. Side asymmetry in pelvic floor muscle tension is claimed to induce pelvic malalignment. However, its nature and amplitude are not clear. There is a need for non-invasive and reliable assessment method. An intervention experiment of unilateral pelvic floor muscle activation on healthy females was performed using image data for intra-subject comparison of normal and altered configuration of bony pelvis. Sequent magnetic resonance imaging of 14 females in supine position was performed with 1.5 T static body coil in coronal orientation. The intervention, surface functional electrostimulation, was applied to activate pelvic floor muscles on the right side. Spatial coordinates of 23 pelvic landmarks were localized in each subject and registered by specially designed magnetic resonance image data processing tool (MPT2006), where individual error calculation; data registration, analysis and 3D visualization were interfaced. The effect of intervention was large (Cohen's d=1.34). We found significant differences in quantity (P<0.01) and quality (P=0.02) of normal and induced pelvic displacements. After pelvic floor muscle activation on the right side, pelvic structures shifted most frequently to the right side in ventro-caudal direction. The right femoral head, the right innominate and the coccyx showed the largest displacements. The consequences arising from the capacity of pelvic floor muscles to displace pelvic bony structures are important to consider not only in management of malalignment syndrome but also in treatment of incontinence. The study has demonstrated benefits associated with processing of magnetic resonance image data within pelvic region with high localization and registration reliability.

To determine whether sarcopenia is an independent predictor of mortality in geriatric acetabular fractures. Retrospective cohort. American College of Surgeons Level I trauma center. One hundred and forty-six patients over the age 60 with acetabular fractures treated at our institution over a 12-year period. The primary outcome was 1-year mortality, collected using the Social Security Death Index. We used the psoas:lumbar vertebral index (PLVI), calculated using the cross-sectional area of the L4 vertebral body and the left and right psoas muscles, to assess for sarcopenia. Using a multivariate logistic regression model, we found that low PLVI was associated with increased 1-year mortality (P = 0.046) when controlling for age, gender, Charlson Comorbidity Index, Injury Severity Score (ISS), smoking status, and associated pelvic ring injury. Increasing age and ISS also showed a relationship with 1-year mortality in this cohort (P < 0.001, P < 0.001, respectively). We defined sarcopenia as those patients in the lowest quartile of PLVI. The mortality rate of this cohort was 32.4%, compared with 11.0% in patients without sarcopenia (odds ratio 4.04; 95% confidence interval 1.62-10.1). Age >75 years, ISS >14, and sarcopenia had 1-year mortality rates of 37.1%, 30.9%, and 32.4%, respectively. In patients with all 3 factors, the mortality rate was 90%. Sarcopenia is an independent risk factor for 1-year mortality in elderly patients with acetabular fractures. This study highlights the importance of objective measures to assess frailty in elderly patients who have sustained fractures about the hip and pelvis. Prognostic Level III.

The aim of this study was to determine if certain occupations or socioeconomic levels are associated with pelvic organ prolapse. Investigators at six American sites performed pelvic organ prolapse quantification examinations on women presenting for routine gynecologic care. Between September 1999 and March 2002, 1,004 patients were examined. Severe pelvic organ prolapse was defined as the leading edge being 1 cm or more beyond the hymeneal ring. The data was analyzed with the Kruskal-Wallis analysis of variance, Bonferroni test, multiple logistic regression, and descriptive statistics. The prevalence of severe pelvic organ prolapse in our group was 4.3%. Women who were laborers/factory workers had significantly more severe prolapse than the other job categories (p < 0.001). Women with annual income of Dollars 10,000 or less had significantly more severe pelvic organ prolapse than other income groups (p < 0.001). These differences persisted even when controlling for age, race, number of deliveries, body mass index >30, and smoking status (all p < 0.001). Laborers/factory worker jobs and an annual household income of Dollars 10,000 or less are associated with severe pelvic organ prolapse.

Mechanical improvement of metal reinforcement rings for a finite ring-shaped superconducting bulk

NASA Astrophysics Data System (ADS)

Huang, Chen-Guang; Zhou, You-He

2018-03-01

As a key technique, reinforcement of type-II superconducting bulks with metal rings can efficiently improve their mechanical properties to enhance the maximum trapped field. In this paper, we study the magnetostrictive and fracture behaviors of a finite superconducting ring bulk reinforced by three typical reinforcing structures composed of metal rings during the magnetizing process by means of the minimization of magnetic energy and the finite element method. After a field-dependent critical current density is adopted, the magnetostriction, pinning-induced stress, and crack tip stress intensity factor are calculated considering the demagnetization effects. The results show that the mechanical properties of the ring bulk are strongly dependent on the reinforcing structure and the material and geometrical parameters of the metal rings. Introducing the metal ring can significantly reduce the hoop stress, and the reduction effect by internal reinforcement is much improved relative to external reinforcement. By comparison, bilateral reinforcement seems to be the best candidate structure. Only when the metal rings have particular Young's modulus and radial thickness will they contribute to improve the mechanical properties the most. In addition, if an edge crack is pre-existing in the ring bulk, the presence of metal rings can effectively avoid crack propagation since it reduces the crack tip stress intensity factor by nearly one order of magnitude.

The use of antibiotic prophylaxis and debridement is controversial when treating low- and high-velocity gunshot-induced fractures, and established treatment guidelines are currently unavailable. The purpose of this review was to evaluate the literature for the prophylactic antibiotic and debridement policies for (1) low-velocity gunshot fractures of the extremities, joints, and pelvis and (2) high-velocity gunshot fractures of the extremities. Low-velocity gunshot fractures of the extremities were subcategorized into operative and non-operative cases, whereas low-velocity gunshot fractures of the joints and pelvis were evaluated based on the presence or absence of concomitant bowel injury. In the absence of surgical necessity for fracture care such as concomitant absence of gross wound contamination, vascular injury, large soft-tissue defect, or associated compartment syndrome, the literature suggests that superficial debridement for low-velocity ballistic fractures with administration of antibiotics is a satisfactory alternative to extensive operative irrigation and debridement. In operative cases or those involving bowel injuries secondary to pelvic fractures, the literature provides support for and against extensive debridement but does suggest the use of intravenous antibiotics. For high-velocity ballistic injuries, the literature points towards the practice of extensive immediate debridement with prophylactic intravenous antibiotics. Our systematic review demonstrates weak evidence for superficial debridement of low-velocity ballistic fractures, extensive debridement for high-velocity ballistic injuries, and antibiotic use for both types of injury. Intra-articular fractures seem to warrant debridement, while pelvic fractures with bowel injury have conflicting evidence for debridement but stronger evidence for antibiotic use. Given a relatively low number of studies on this subject, we recommend that further high-quality research on the debridement and

Roughly half of the femoral fracture patients diagnosed with AFF according to the criteria suggested by a task force of the American Society for Bone and Mineral Research (ASBMR) have not undergone bisphosphonate (BP) therapy. One suspected cause of such fractures is severe bone loss due to osteomalacia, but the pathogenesis remains unknown. We report a case of an 84-year-old woman with AFF not treated by BP therapy, in whom underlying osteomalacia was histologically diagnosed. The involvement of femoral curvature and spino-pelvic malaligment in the fracture in the present case was considered.

Post traumatic arthritis and avascular necrosis of the femoral head are common complications after operatively treated acetabular fractures. This may cause severe disabilities for the patient, necessitating a total hip arthroplasty. Even though an arthroplasty may provide good symptomatic relief, the long-term results are more uncertain and no consensus exists according to preferred prosthetic designs. With this cohort study, we aimed to investigate the medium to long term arthroplasty survival and clinical results of total hip arthroplasty after operatively treated acetabular fractures. We included 52 patients treated with a secondary total hip arthroplasty at a median of 2.4 (0.1-14.1) years after an operatively treated acetabular fracture. The median age was 54 (11-82) years. Cemented arthroplasty was used for 33 patients, 10 patients had an uncemented arthroplasty and 9 patients received a hybrid arthroplasty. Average follow up was 8.0 (SD 5.0) years. Ten-year revision free arthroplasty survival was 79%. Uncemented arthroplasties had a significantly worse 10-year survival of 57%. Arthroplasties performed at a centre without a pelvic fracture service also had a significantly worse 10-years survival of 51%. Cox regression showed similar results with an 8-fold increase in risk of revision for both uncemented arthroplasties and operations performed at a non-pelvic trauma centre. Total hip arthroplasty secondary to an operatively treated acetabular fracture provides good symptomatic relief. These patients are, however, complex cases and are probably best treated at specialist centres with both pelvic trauma surgeons and arthroplasty surgeons proficient in complex revisions present.

The injuries caused by earthquakes are often complex and of various patterns. Our study included all fracture inpatients from the Yushu earthquake (1323 in total), to learn more about the incidence and distribution of fractures during earthquakes. A retrospective study of the clinical characteristics of hospitalized fracture patients after the 2010 Yushu earthquake was conducted from December 20 to 25, 2010.We reviewed medical records of hospitalized patients who had been evacuated from the Yushu earthquake area between April 14 and June 15, 2010, from 57 hospitals, and also reviewed more than 100 documents assembled from daily medical rescue and disease prevention reports submitted by the frontline rescue organizations. In total, 78.0% of fracture patients were admitted to the hospital within 3 days after the earthquake. There were 1323 patients who presented with 1539 fractures. The most common fracture occurred in the lower limbs, followed by spinal, pelvic, and shoulder-upper limb fractures. The end of the thoracic vertebra and the lumbar vertebra were the high-risk sites for vertebral fractures. A total of 38 patients became paraplegic. A 2-level spatial clustering was detected among the 193 patients presenting with 2 fractures. Analysis profiles of the injuries and clinical features of patients with earthquake-related fractures will positively impact rescue efforts and the treatment of fracture injuries caused by possible future natural disasters. We should assemble orthopedic-related medications and surgical equipment, and allocate them promptly after a major earthquake. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Hip fracture is associated with high morbidity and mortality. Pelvic external beam radiotherapy (EBRT) is known to increase the risk of hip fractures in women but the effect in men is unknown. Methods 45,662 men aged ≥66 years, diagnosed with prostate cancer in 1992–2004 were identified from the SEER-Medicare database. Using Kaplan-Meier methods and Cox proportional hazards models, the primary outcome of hip fracture risk was compared among men who received radical prostatectomy (RP), EBRT, EBRT+androgen suppression therapy (AST) or AST alone, controlling for age, osteoporosis, race and other comorbidities. A secondary outcome was distal forearm fractures as an indicator of fragility fracture risk outside the radiation field. Results After controlling for covariates, EBRT increased the risk of hip fractures by 76% (HR 1.76, 95% CI 1.38–2.40) without increasing the risk of distal forearm fractures (HR 0.80, 95% CI 0.56–1.14). Combination therapy with EBRT+AST increased the risk of hip fracture 145% relative to RP (HR 2.45, 95% CI 1.88–3.19) and by 40% relative to EBRT (HR 1.40, 95% CI 1.17–1.68). EBRT+AST increased the risk of distal forearm fracture by 43% relative to RP (HR 1.43, 95% CI 0.97–2.10). The number needed to treat to result in 1 hip fracture through 10 years was 51 (95% CI 31–103). Conclusion In men with prostate cancer, pelvic 3-D conformal EBRT is associated with a 76% increased risk of hip fracture. This risk is slightly increased further by the addition of short-course AST to EBRT. This risk associated with EBRT is site-specific as there is no increase in the risk of fall-related fractures outside the radiation field. PMID:21412999

García-García, Alejandra; Ramírez-Durán, Ninfa; Sandoval-Trujillo, Horacio

2017-01-01

Introduction Actinomycosis is a chronic bacterial infection caused by Actinomyces, Gram-positive anaerobic bacteria. Its symptomatology imitates some malignant pelvic tumours, tuberculosis, or nocardiosis, causing abscesses and fistulas. Actinomycoses are opportunistic infections and require normal mucous barriers to be altered. No epidemiological studies have been conducted to determine prevalence or incidence of such infections. Objective To analyse the clinical cases of pelvic actinomycosis reported worldwide, to update the information about the disease. Methods A systematic review of worldwide pelvic actinomycosis cases between 1980 and 2014 was performed, utilising the PubMed, Scopus, and Google Scholar databases. The following information was analysed: year, country, type of study, number of cases, use of intrauterine device (IUD), final and initial diagnosis, and method of diagnosis. Results 63 articles met the search criteria, of which 55 reported clinical cases and 8 reported cross-sectional studies. Conclusions Pelvic actinomycosis is confusing to diagnose and should be considered in the differential diagnosis of pelvic chronic inflammatory lesions. It is commonly diagnosed through a histological report, obtained after a surgery subsequent to an erroneous initial diagnosis. A bacterial culture in anaerobic medium could be useful for the diagnosis but requires a controlled technique and should be performed using specialised equipment. PMID:28684963

Clinical usefulness of fracture site in situ block on lumbar spine transverse process fracture.

Lumbar spine transverse process fractures (LSTPFs) are uncommon and frequently overlooked on plain film radiographs. Even when recognized, they are often regarded as trivial and minimally painful injuries compared with combined serious major abdominal, pelvic, and spinal injuries. Conservative treatments are usually offered to patients with LSTPFs. This report presents 4 cases of LSTPFs where symptoms did not improve after more than 1 week of conservative management. Local anesthetics and steroids were injected directly into the fracture site under computed tomography guidance, referred to as a fracture site in situ block, in an attempt to accelerate the return to daily lives and professional activities. Three of the 4 patients returned to their daily lives almost immediately after completing the procedure. Although the procedure was appropriately performed at L4, 1 patient still complained of pain. This patient's all films were meticulously re-examined, and it was determined that a transverse process fracture was present at not only L4 but also L1. This report introduces a method of active treatment to help patients with LSTPFs quickly return to their daily lives and professional activities. The positive results in these cases suggest that fracture site in situ block might be a useful option for treating patients with LSTPFs. © 2014 World Institute of Pain.

Fracture reduction and primary ankle arthrodesis: a reliable approach for severely comminuted tibial pilon fracture.

PubMed

Beaman, Douglas N; Gellman, Richard

2014-12-01

Posttraumatic arthritis and prolonged recovery are typical after a severely comminuted tibial pilon fracture, and ankle arthrodesis is a common salvage procedure. However, few reports discuss the option of immediate arthrodesis, which may be a potentially viable approach to accelerate overall recovery in patients with severe fracture patterns. (1) How long does it take the fracture to heal and the arthrodesis to fuse when primary ankle arthrodesis is a component of initial fracture management? (2) How do these patients fare clinically in terms of modified American Orthopaedic Foot and Ankle Society (AOFAS) scores and activity levels after this treatment? (3) Does primary ankle arthrodesis heal in an acceptable position when anterior ankle arthrodesis plates are used? During a 2-year period, we performed open fracture reduction and internal fixation in 63 patients. Eleven patients (12 ankles) with severely comminuted high-energy tibial pilon fractures were retrospectively reviewed after surgical treatment with primary ankle arthrodesis and fracture reduction. Average patient age was 58 years, and minimum followup was 6 months (average, 14 months; range, 6-22 months). Anatomically designed anterior ankle arthrodesis plates were used in 10 ankles. Ring external fixation was used in nine ankles with concomitant tibia fracture or in instances requiring additional fixation. Clinical evaluation included chart review, interview, the AOFAS ankle-hindfoot score, and radiographic evaluation. All of the ankle arthrodeses healed at an average of 4.4 months (range, 3-5 months). One patient had a nonunion at the metaphyseal fracture, which healed with revision surgery. The average AOFAS ankle-hindfoot score was 83 with 88% having an excellent or good result. Radiographic and clinical analysis confirmed a plantigrade foot without malalignment. No patients required revision surgery for malunion. Primary ankle arthrodesis combined with fracture reduction for the severely comminuted

Fracture mechanics analysis results are presented from the following structures/components analyzed at Marshall Space Flight Center (MSFC) between 1982 and 1989: space shuttle main engine (SSME), Hubble Space Telescope (HST), external tank attach ring, B-1 stand LOX inner tank, and solid rocket booster (SRB). Results from the SSME high pressure fuel turbopump (HPFTP) second stage blade parametric analysis determine a critical flaw size for a wide variety of stress intensity values. The engine 0212 failure analysis was a time dependent fracture life assessment. Results indicated that the disk ruptured due to an overspeed condition. Results also indicated that very small flaws in the curvic coupling area could propagate and lead to failure under normal operating conditions. It was strongly recommended that a nondestructive evaluation inspection schedule be implemented. The main ring of the HST, scheduled to launch in 1990, was analyzed by safe-life and fail-safe analyses. First safe-life inspection criteria curves for the ring inner and outer skins and the fore and aft channels were derived. Afterwards the skins and channels were determined to be fail-safe by analysis. A conservative safe-life analysis was done on the 270 redesign external tank attach ring. Results from the analysis were used to determine the nondestructive evaluation technique required.

We sought to assess the effects of fracture injuries on maternal and fetal/neonatal outcomes in a large obstetric population. We performed a retrospective cohort study using a database in which maternal and neonatal hospital discharge summaries were linked with birth and death certificates to identify any relation between maternal fractures and maternal and perinatal morbidity. Fracture injuries and perinatal outcomes were identified with the use of the International Classification of Diseases, 9th revision, Clinical Modification codes. Outcomes were further subdivided on the basis of anatomic site of fracture. A total of 3292 women with > or = 1 fractures were identified. Maternal mortality (odds ratio, 169 [95% CI, 83.2,346.4]) and morbidity (abruption and blood transfusion) rates were increased significantly in women who were delivered during hospitalization for their injury. Women who were discharged undelivered continued to have delayed morbidity, which included a 46% increased risk of low birth weight infants (odds ratio, 1.5 [95% CI, 1.3,1.7]) and a 9-fold increased risk of thrombotic events (odds ratio, 9.2 [95% CI, 1.3,65.7]) Pelvic fractures had the worst outcomes. Fractures during pregnancy are an important marker for poor perinatal outcomes.

Delayed hemothorax after blunt torso injury is rare, but might be associated with significant morbidity and mortality. We present a case of delayed hemothorax bleeding from phrenic artery injury in a 24-year-old woman. The patient suffered from multiple rib fractures on the right side, a right hemopneumothorax, thoracic vertebral injury and a pelvic bone fracture after a fall from a fourth floor window. Delayed hemothorax associated with phrenic artery bleeding, caused by a stab injury from a fractured rib segment, was treated successfully by a minimally invasive thoracoscopic surgery. Here, we have shown that fracture of a lower rib or ribs might be accompanied by delayed massive hemothorax that can be rapidly identified and promptly managed by thoracoscopic means.

Chronic pelvic pain.

PubMed

2016-06-02

Chronic pelvic pain (CPP) affects about 10-40% of women presenting to a physician, and is characterised by pain within the minor pelvis persisting for over 6 months. The Medline database was searched using the key words 'chronic pelvic pain' and 'pelvic congestion syndrome', published in English during the past 15 years. The condition markedly deteriorates the quality of life of the affected. Its aetiology has not been fully described and elucidated, although organic, functional and psychosomatic factors are implicated. Pain associated with parametrial varices was defined as pelvis congestion syndrome (PCS). Since the aetiology of CPP is complex, multi-directional diagnostic procedures are required. The main diagnostic methods employed are imaging examinations (ultrasound, computer tomography, magnetic resonance). Advances in interventional radiology considerably contributed to the CPP treatment. Currently, embolization of parametrial vessels is one of the most effective methods to relieve pain associated with pelvic congestion syndrome. Due to the complex aetiology of chronic pelvic pain, the most beneficial effects are obtained when the therapy is based on cooperation of the gynaecologist, physiotherapist, psychologist and interventional radiologist.

Objective: To describe the diagnosis and management of a competitive male basketball player with discogenic low back pain and presence of an old posterior ring apophyseal fracture (PRAF). This case will highlight the importance of early recognition and considerations regarding patient management for this differential of radiating low back pain. Clinical Features: A 21-year-old provincial basketball player presented with recurrent radiating low back pain into the left groin and lower limb. After several weeks of persistent symptoms including pain, muscle weakness, and changes in the Achilles deep tendon reflex, imaging was obtained that revealed a large disc extrusion with an old posterior ring apophyseal fracture. In collaboration with a spine surgeon and family physician, the patient was treated using a conservative, multimodal approach. Treatment consisted of graded mobilizations, spinal manipulative therapy, interferential current, and soft tissue therapy to the lumbar spine. Rehabilitation exercises focused on centralizing symptoms and improving strength, proprioception and function of the lower limb. After a period of 8 weeks, the patient was able to complete all activities of daily living without pain in addition to returning to basketball practice. Summary: PRAF is a unique condition in the immature spine and recent evidence suggests that those involved in sports requiring repetitive motion of the lumbar spine may be at increased risk. The astute clinician must consider this differential in young populations presenting with discogenic low back pain, as a timely diagnosis and necessary referral may allow for effective conservative management to reduce symptoms. Equally as important, one must be aware of the complications from PRAF as a contributing source of low back pain and dysfunction into adulthood. Knowing when to refer for advanced imaging and/or a surgical consult given the variable clinical presentation and prognosis is an essential component to care

This in vitro biomechanical experiment has shown that the multidirectional titanium fixation (MTF) and pelvic brim long screws fixation (PBSF) provided the strongest fixation for quadrilateral plate fracture; the better biomechanical performance of the AFRIF compared with the T-shaped plate fixation (TPF), L-shaped plate fixation (LPF), and H-shaped plate fixation (HPF); AFRIF gives reasonable stability of treatment for quadrilateral plate fracture and may offer a better solution for comminuted quadrilateral plate fractures or free floating medial wall fracture and be reliable in preventing protrusion of femoral head.

Up to now, field studies set up to measure field-saturated hydraulic conductivity to evaluate contamination risks, have employed small cylinders that may not be representative of the scale of measurements in heterogeneous media. In this study, a large adjustable ring infiltrometer was designed to be installed on-site directly on rock to measure its field-saturated hydraulic conductivity. The proposed device is inexpensive and simple to implement, yet also very versatile, due to its large adjustable diameter that can be fixed on-site. It thus allows an improved representation of the natural system's heterogeneity, while also taking into consideration irregularities in the soil/rock surface. The new apparatus was tested on an outcrop of karstic fractured limestone overlying the deep Murge aquifer in the South of Italy, which has recently been affected by untreated sludge disposal, derived from municipal and industrial wastewater treatment plants. The quasi-steady vertical flow into the unsaturated fractures was investigated by measuring water levels during infiltrometer tests. Simultaneously, subsurface electrical resistivity measurements were used to visualize the infiltration of water in the subsoil, due to unsaturated water flow in the fractures. The proposed experimental apparatus works well on rock outcrops, and allows the repetition of infiltration tests at many locations in order to reduce model uncertainties in heterogeneous media. ?? 2009 Springer-Verlag.

Geometrical and mechanical constraints on the formation of ring-fault calderas

NASA Astrophysics Data System (ADS)

Folch, A.; Martí, J.

2004-04-01

Ash-flow, plate-subsidence (piston-like) calderas are bounded by a set of arcuated sub-vertical collapse faults named ring-faults. Experimental studies on caldera formation, performed mostly using spherical or cylindrical magma chamber geometries, find that the resulting ring-faults correspond to steeply outward dipping reverse faults, and show that pre-existing fractures developed during pre-eruptive phases of pressure increase may play a major role in controlling the final collapse mechanism, a situation that should be expected in small to medium sized ring-fault calderas developed on top of composite volcanoes or volcanic clusters. On the other hand, some numerical experiments indicate that large sill-like, elongated magma chambers may induce collapse due to roof bending without fault reactivation, as seems to occur in large plate-subsidence calderas formed independently of pre-existing volcanoes. Also, numerical experiments allow the formation of nearly vertical or steeply inward dipping normal ring-faults, in contrast with most of the analogue models. Using a thermoelastic model, we investigate the geometrical and mechanical conditions to form ring-fault calderas, in particular the largest ones, without needing a previous crust fracturing. Results are given in terms of two dimensionless geometrical parameters, namely λ and e. The former is the chamber extension to chamber depth ratio, whereas the latter stands for the chamber eccentricity. We propose that the ( λ, e) pair determinates two different types of ring-fault calderas with different associated collapse regimes. Ring-fault region A is related to large plate-subsidence calderas (i.e. Andean calderas or Western US calderas), for which few depressurisation is needed to set up a collapse initially governed by flexural bending of the chamber roof. In contrast, ring-fault region B is related to small to moderate sized calderas (i.e. composite volcano calderas), for which much depressurisation is needed

Purpose  Accurate assessment of cup orientation on postoperative pelvic radiographs is essential for evaluating outcome after THA. Here, we present a novel method for correcting measurement inaccuracies due to pelvic tilt and rotation. Method  In an experimental setting, a cup was implanted into a dummy pelvis, and its final position was verified via CT. To show the effect of pelvic tilt and rotation on cup position, the dummy was fixed to a rack to achieve a tilt between + 15° anterior and -15° posterior and 0° to 20° rotation to the contralateral side. According to Murray's definitions of anteversion and inclination, we created a novel corrective procedure to measure cup position in the pelvic reference frame (anterior pelvic plane) to compensate measurement errors due to pelvic tilt and rotation. Results  The cup anteversion measured on CT was 23.3°; on AP pelvic radiographs, however, variations in pelvic tilt (± 15°) resulted in anteversion angles between 11.0° and 36.2° (mean error 8.3°± 3.9°). The cup inclination was 34.1° on CT and ranged between 31.0° and 38.7° (m. e. 2.3°± 1.5°) on radiographs. Pelvic rotation between 0° and 20° showed high variation in radiographic anteversion (21.2°-31.2°, m. e. 6.0°± 3.1°) and inclination (34.1°-27.2°, m. e. 3.4°± 2.5°). Our novel correction algorithm for pelvic tilt reduced the mean error in anteversion measurements to 0.6°± 0.2° and in inclination measurements to 0.7° (SD± 0.2). Similarly, the mean error due to pelvic rotation was reduced to 0.4°± 0.4° for anteversion and to 1.3°± 0.8 for inclination. Conclusion  Pelvic tilt and pelvic rotation may lead to misinterpretation of cup position on anteroposterior pelvic radiographs. Mathematical correction concepts have the potential to significantly reduce these errors, and could be implemented in future radiological software tools.

Women with anorexia nervosa have reduced skeletal mass. Both anorexia and osteopenia are less common in men. We describe a 22-year-old man with anorexia nervosa and severe osteopenia involving both cortical and trabecular bone who developed a pelvic fracture and multiple vertebral compression fractures. He was found to have secondary hypogonadotropic hypogonadism that was reversible with weight gain. This case illustrates the need to consider osteopenia as a potential complication of anorexia nervosa in males as well as females.

Fractures of the Sacrum After Chemoradiation for Rectal Carcinoma: Incidence, Risk Factors, and Radiographic Evaluation

Purpose: Sacral insufficiency fractures after adjuvant radiation for rectal carcinoma can present similarly to recurrent disease. As a complication associated with pelvic radiation, it is important to be aware of the incidence and risk factors associated with sacral fractures in the clinical assessment of these patients. Methods and Materials: Between 1998 and 2007, a total of 582 patients with locally advanced rectal carcinoma received adjuvant chemoradiation and surgical excision. Of these, 492 patients had imaging studies available for review. Hospital records and imaging studies from all 492 patients were retrospectively evaluated to identify risk factors associated with developing a sacralmore » insufficiency fracture. Results: With a median follow-up time of 3.5 years, the incidence of sacral fractures was 7.1% (35/492). The 4-year sacral fracture free rate was 0.91. Univariate analysis showed that increasing age ({>=}60 vs. <60 years), female sex, and history of osteoporosis were significantly associated with shorter time to sacral fracture (P=.01, P=.004, P=.001, respectively). There was no significant difference in the time to sacral fracture for patients based on stage, radiotherapy dose, or chemotherapy regimen. Multivariate analysis showed increasing age ({>=}60 vs. <60 years, hazard ratio [HR] = 2.50, 95% confidence interval [CI] = 1.22-5.13, P=.01), female sex (HR = 2.64, CI = 1.29-5.38, P=.008), and history of osteoporosis (HR = 3.23, CI = 1.23-8.50, P=.02) were independent risk factors associated with sacral fracture. Conclusions: Sacral insufficiency fractures after pelvic radiation for rectal carcinoma occur more commonly than previously described. Independent risk factors associated with fracture were osteoporosis, female sex, and age greater than 60 years.« less

Hip fracture is associated with high morbidity and mortality. Pelvic external beam radiotherapy (EBRT) is known to increase the risk of hip fractures in women, but the effect in men is unknown. From the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, 45,662 men who were aged ≥66 years and diagnosed with prostate cancer in 1992-2004 were identified. By using Kaplan-Meier methods and Cox proportional hazards models, the primary outcome of hip fracture risk was compared among men who received radical prostatectomy (RP), EBRT, EBRT plus androgen suppression therapy (AST), or AST alone. Age, osteoporosis, race, and other comorbidities were statistically controlled. A secondary outcome was distal forearm fracture as an indicator of the risk of fall-related fracture outside the radiation field. After covariates were statistically controlled, the findings showed that EBRT increased the risk of hip fractures by 76% (hazards ratio [HR], 1.76; 95% confidence interval [CI], 1.38-2.40) without increasing the risk of distal forearm fractures (HR, 0.80; 95% CI, 0.56-1.14). Combination therapy with EBRT plus AST increased the risk of hip fracture 145% relative to RP alone (HR, 2.45; 95% CI, 1.88-3.19) and by 40% relative to EBRT alone (HR, 1.40; 95% CI, 1.17-1.68). EBRT plus AST increased the risk of distal forearm fracture by 43% relative to RP alone (HR, 1.43; 95% CI, 0.97-2.10). The number needed to treat to result in 1 hip fracture during a 10-year period was 51 patients (95% CI, 31-103). In men with prostate cancer, pelvic 3-D conformal EBRT was associated with a 76% increased risk of hip fracture. This risk was slightly increased further by the addition of short-course AST to EBRT. This risk associated with EBRT must be site-specific as there was no increase in the risk of fall-related fractures in bones that were outside the radiation field.

To report the repair of tibial diaphyseal fractures in 2 calves using a circular external skeletal fixator (CEF). Clinical report. Crossbred calves (n=2; age: 6 months; weight: 55 and 60 kg). Mid-diaphyseal tibial fractures were repaired by the use of a 4-ring CEF (made of aluminum rings with 2 mm K-wires) alone in 1 calf and in combination with hemicerclage wiring in 1 calf. Both calves had good weight bearing with moderate lameness postoperatively. Fracture healing occurred by day 60 in 1 calf and by day 30 in calf 2. The CEF was well maintained and tolerated by both calves through fracture healing. Joint mobility and limb usage improved gradually after CEF removal. CEF provided a stable fixation of tibial fractures and healing within 60 days and functional recovery within 90 days. CEF can be safely and successfully used for the management of selected tibial fractures in calves.

Pelvic floor dysfunctions are frequently seen in females. The human pelvic floor is a complex structure and heavily stressed throughout female life. Recent findings in the functional anatomy of the pelvic floor have led to a much better understand-ing, on the basis of which enormous improvements in the therapeutic options have arisen. The pelvic floor activity is regulated by three main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor -organs, bladder and rectum. For different reasons laxity in the vagina or its supporting ligaments as a result of altered connective tissue can distort this functional anatomy. A variety of symptoms can derive from these pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, faecal incontinence, obstructive bowel disease syndrome and pelvic pain. Pelvic floor reconstruction is nowadays driven by the concept that in the case of pelvic floor symptoms restoration of the anatomy will translate into restoration of the physiology and ultimately improve the patients' symptoms. The exact surgical reconstruction of the anatomy is there-fore almost exclusively focused on the restoration of the lax pelvic floor ligaments. An exact identification of the anatomic lesions preoperatively is eminently necessary, to allow for an exact anatomic reconstruction with respect to the muscular forces of the pelvic floor.

Congenital factor, obesity, aging, pregnancy and childbirth are the main risk factors for female pelvic floor disorders (urinary incontinence, anal incontinence, pelvic organ prolapse, dyspareunia). Vaginal delivery may cause injury to the pudendal nerve, the anal sphincter, or the anal sphincter. However the link between these injuries and pelvic floor symptoms is not always determined and we still ignore what might be the ways of prevention. Of the many obstetrical methods proposed to prevent postpartum symptoms, episiotomy, delivery in vertical position, delayed pushing, perineal massage, warm pack, pelvic floor rehabilitation, results are disappointing or limited. Caesarean section is followed by less postnatal urinary incontinence than vaginal childbirth. However this difference tends to disappear with time and following childbirth. Limit the number of instrumental extractions and prefer the vacuum to forceps could reduce pelvic floor disorders after childbirth. Ultrasound examination of the anal sphincter after a second-degree perineal tear is useful to detect and repair infra-clinic anal sphincter lesions. Scientific data is insufficient to justify an elective cesarean section in order to avoid pelvic floor symptoms in a woman without previous disorders. Copyright 2010 Elsevier Masson SAS.

Anorectal and Pelvic Pain

Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the three most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first two conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacologic, behavioral, and physical therapy. Opioids should not be avoided, and surgery has a limited role, primarily in refractory interstitial cystitis. PMID:27712641

Pelvic denervation procedures for dysmenorrhea.

Ramirez, Christina; Donnellan, Nicole

2017-08-01

Chronic pelvic pain and dysmenorrhea are common conditions affecting reproductive-age women. Surgical pelvic denervation procedures may be a treatment option for women with midline dysmenorrhea, in which medical management is declined by the patient, ineffective at managing symptoms, or medically contraindicated. This review describes the surgical techniques and complications associated with pelvic denervation procedures as well as the current evidence for these procedures in women with primary dysmenorrhea and dysmenorrhea secondary to endometriosis. Presacral neurectomy is the preferred pelvic denervation procedure in patients with primary dysmenorrhea and midline chronic pelvic pain associated with endometriosis. In patients with endometriosis presacral neurectomy is a useful adjunct to excision or ablation of all endometrial lesions to improve postoperative pain relief. There is no additional patient benefit of performing combined presacral neurectomy and uterine nerve ablation procedures. Pelvic denervation procedures can be performed safely and quickly with a low risk of complication if the surgeon is knowledgeable and skilled in operating in the presacral space. Patients should be adequately counseled on expected success rates and potential complications associated with pelvic denervation procedures.

Widely used in traumatic pelvic ring fractures, the iliosacral (IS) screw technique for spino-pelvic fixation remains anecdotal in adult spinal deformity. The objective of this study was to assess anatomical variability of the adult upper sacrum and to provide a user guide of spino-pelvic fixation with IS screws in adult spinal deformity. Anatomical variability of the upper sacrum according to age, gender, height and weight was sought on 30 consecutive pelvic CT-scans. Thus, a user guide of spino-pelvic fixation with IS screws was modeled and assessed on ten CT-scans as described below. Two invariable landmarks usable during the surgical procedure were defined: point A (corresponding to the connector binding the IS screw to the spinal rod), equidistant from the first posterior sacral hole and the base of the S1 articular facet and 10 mm-embedded into the sacrum; point B (corresponding to the tip of the IS screw) located at the junction of the anterior third and middle third of the sacral endplate in the sagittal plane and at the middle of the endplate in the coronal plane. Point C corresponded to the intersection between the A-B direction and the external facet of the iliac wing. Three-dimensional reconstructions modeling the IS screw optimal direction according to the A-B-C straight line were assessed. Age had no effect on the anatomy of the upper sacrum. The distance between the base of the S1 superior articular facet and the top of the first posterior sacral hole was correlated with weight (r = 0.6; 95% CI [0.6-0.9]); p < 0.001). Sacral end-plate thickness increased for male patients (p < 0.001) and was strongly correlated with height (r = 0.6; 95% CI [0.29-0.75]); p < 0.001) and weight (r = 0.8; 95% CI [0.6-0.9]); p < 0.001). The thickness of the inferior part of the S1 vertebral body increased in male patients (p < 0.001). Other measured parameters slightly varied according to gender, height and weight.

To evaluate the clinical response and success rate after periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome and to report the safety of endovascular treatment and its rate of complications. Retrospective cohort of patients undergoing endovascular treatment of pelvic congestion syndrome in our department from January 2012 to November 2015. Data were analyzed based on patient background, imaging findings, embolized veins, rate of complications, and clinical response as indicated by the visual analog pain scale. We performed periuterine varices embolization in 22 patients during the study, four of which required a second embolization. Seventeen patients reported a reduction in pelvic pain after the first embolization and three patients reported a reduction in pelvic pain after the second embolization. Minor complications were observed in our patients, such as postural hypotension, postoperative pain, and venous perforation during the procedure, without clinical repercussion. Periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome appears to be an effective and safe technique.

Does a pelvic belt reduce hip adduction weakness in pregnancy-related posterior pelvic girdle pain? A case-control study.

The cause of non-specific lumbopelvic pain is unknown. Pregnancy-related pelvic girdle pain seems to be a subgroup that deserves a specific treatment. One of the options is the use of a pelvic belt. To objectify the influence of a pelvic belt in patients with pelvic girdle pain. Case-control study. Outpatient clinic. A total of 49 women with long-lasting posterior pelvic girdle pain and 37 parous women of the same age group without pelvic girdle pain. Hip adduction force was measured by asking the participant to squeeze a hand-held dynamometer between the knees. This was firstly performed without a pelvic belt and then with a pelvic belt. The increase of hip adduction force after applying the pelvic belt was expressed in percentages. After tightening a pelvic belt hip adduction force increased 25.9±33.9% in patients with pelvic girdle pain (P<0.0001) and 1.0±8.6% in participants without (P=0.67). The difference between groups was significant (P<0.00001). A pelvic belt has a positive influence on hip adduction force in pregnancy-related posterior pelvic girdle pain. The results show an objective positive effect of the pelvic belt in women with long-lasting pregnancy-related posterior pelvic girdle pain in a test-situation. The results support the idea that the use of a belt could be part of a multidisciplinary rehabilitation of those patients.

Retrospective medical record review. The purpose of this study was to describe the incidence of other injuries that commonly occur in conjunction with cervical spine fractures and dislocations. Cervical spine fractures are often associated with other significant traumatic conditions, which may also require prompt diagnosis and management. However, the relative incidences of the injuries that occur in conjunction with various cervical spine fractures have not been well documented. The radiographic reports of all patients who underwent CT scans of the cervical spine at a single level 1 trauma center over a 10-year period were reviewed. The medical records of individuals with acute, nonpenetrating fractures of the cervical spine were further assessed for any associated traumatic pathology including noncontiguous spine injuries and those affecting other organ systems (i.e., head and neck, intrathoracic, intra-abdominal/pelvic, and nonspinal orthopedic disorders). A total of 13,896 CT scans of the cervical spine were performed during this 10-year period of which 492 revealed acute fractures and/or dislocations. Of these subjects, 60% had sustained at least one additional injury. Overall, 57% were noted to have extraspinal injuries (34% head and neck, 17% intrathoracic, 10% intra-abdominal/pelvic, and 30% nonspinal orthopedic conditions) and noncontiguous spinal trauma was present in 19% of these cases (8% cervical injuries, 8% thoracic, and 6% lumbar). In general, the rates of associated injuries observed with occipital condyle and C7 fractures were significantly higher than those recorded for other cervical segments. For patients with a known history of cervical spine trauma, the frequencies of associated injuries were similar across all levels of the cervical spine with the exception of the injuries to the craniocervical junctions. In practice, this means that injuries to the cervical spine can likely be grouped together when considering other possible associated

This study aimed to compare the effectiveness of stabilization exercises and pelvic floor muscle training in women with stage 1 and 2 pelvic organ prolapse. In a total 38 women with pelvic organ prolapse whose average age was 45.60 years, pelvic floor muscles were evaluated with electromyography, and prolapse with pelvic organ prolapse quantification system, and the quality of life with prolapse quality of life questionnaire. Afterwards, the subjects were divided into two groups; stabilization exercise group (n=19) and pelvic floor muscle training group (n=19). Stabilization exercise group were given training for 8 weeks, 3 times a week. Pelvic floor muscle training group were given eight-week home exercises. Each group was assessed before training and after eight weeks. An increase was found in the pelvic muscle activation response in the 2 groups (p≤0.05). There was no difference in EMG activity values between the groups (p>0.05). A difference was found in the values Aa, Ba and C in subjects of each group (p≤0.05), and the TVL, Ap, Bp and D values of subjects in pelvic floor muscle training group (p≤0.05) in the before and after pelvic organ prolapse quantification system assessment, however, no difference was found between the groups (p≤0.05). A positive difference was found in the effect of prolapse sub parameter in each of the two groups, and in general health perception sub parameter in subjects of stabilization exercise group (p<0.05) in the prolapse quality of life questionnaire. It was concluded that both training programs increased the pelvic floor muscle strength, provided a decline in prolapse stages. Stabilization exercise has increased general health perception unlike home training, thus, these exercises can be added to the treatment of women with prolapse.

External fixation of tibial pilon fractures and fracture healing.

PubMed

Ristiniemi, Jukka

2007-06-01

Distal tibial fractures are rare and difficult to treat because the bones are subcutaneous. External fixation is commonly used, but the method often results in delayed union. The aim of the present study was to find out the factors that affect fracture union in tibial pilon fractures. For this purpose, prospective data collection of tibial pilon fractures was carried out in 1998-2004, resulting in 159 fractures, of which 83 were treated with external fixation. Additionally, 23 open tibial fractures with significant > 3 cm bone defect that were treated with a staged method in 2000-2004 were retrospectively evaluated. The specific questions to be answered were: What are the risk factors for delayed union associated with two-ring hybrid external fixation? Does human recombinant BMP-7 accelerate healing? What is the role of temporary ankle-spanning external fixation? What is the healing potential of distal tibial bone loss treated with a staged method using antibiotic beads and subsequent autogenous cancellous grafting compared to other locations of the tibia? The following risk factors for delayed healing after external fixation were identified: post-reduction fracture gap of >3 mm and fixation of the associated fibula fracture. Fracture displacement could be better controlled with initial temporary external fixation than with early definitive fixation, but it had no significant effect on healing time, functional outcome or complication rate. Osteoinduction with rhBMP-7 was found to accelerate fracture healing and to shorten the sick leave. A staged method using antibiotic beads and subsequent autogenous cancellous grafting proved to be effective in the treatment of tibial bone loss. Healing potential of the bone loss in distal tibia was at least equally good as in other locations of the tibia.

Prospective clinical trial in thoracolumbar trauma with 5-year follow-up. To analyze clinical and radiographic outcomes of minimal invasive surgery, and the rational of circumferential fracture treatment with regard to age, degenerative changes, bone mineral density, and global sagittal balance. Non-neurologic fractures with anterior column defect can be treated by posterior percutaneous instrumentation and selective anterior fusion. After consolidation, instrumentation can be removed at 1 year to provide mobility in non-fused segments. Fifty-one patients, 47 (18-75) years, were operated for A2, A3, or B-type fractures. Visual analog scale (VAS) for back pain and Oswestry Disability Index (ODI) were assessed. Radiographic measurements were: sagittal index, regional kyphosis, T4-T12 kyphosis, L1-S1 lordosis, pelvic incidence, pelvic tilt, sacral slope, and T9 tilt. Anterior fusion and facet joints were analyzed on computed tomography (CT) at 1 year. The ODI was 8.8 before accident, 35.4 at 3 months, 17.8 at 2 years, 14.4 at 5 years. The VAS was 2.0 at 3 months and 1.0 at 5 years. The sagittal index was 18.0° preoperatively and 1.0° at 3 months (P < 0.0001). A loss of reduction of 1.1° occurred after implant removal (P = 0.009). Global sagittal balance remained unchanged. Ten patients with osteopenia or osteoporosis had a worse ODI: 24.7 versus 11.9 (P = 0.016), and a greater loss of correction: 4.9° versus 1.3° (P = 0.007). Cages filled with cancellous bone from the fractured vertebra fused regularly. Spontaneous facet joint fusions were observed in two patients at the fracture level in B-type injuries. Percutaneous instrumentation and selective anterior fusion using autologous bone and mesh cages lead to high fusion rates, which provided good long-term clinical results in younger patients with thoracolumbar fractures. Sagittal alignment was maintained after instrumentation removal without damaging paravertebral muscles. Outcomes were worse in

Large impacts provide a mechanism for resurfacing planets through mixing near-surface rocks with deeper material. Central peaks are formed from the dynamic uplift of rocks during crater formation. As crater size increases, central peaks transition to peak rings. Without samples, debate surrounds the mechanics of peak-ring formation and their depth of origin. Chicxulub is the only known impact structure on Earth with an unequivocal peak ring, but it is buried and only accessible through drilling. Expedition 364 sampled the Chicxulub peak ring, which we found was formed from uplifted, fractured, shocked, felsic basement rocks. The peak-ring rocks are cross-cut by dikes and shear zones and have an unusually low density and seismic velocity. Large impacts therefore generate vertical fluxes and increase porosity in planetary crust. Copyright © 2016, American Association for the Advancement of Science.

The authors' intent was to determine the clinical efficacy of comprehensive pelvic floor rehabilitation among women with symptoms of pelvic floor dysfunction (PFD). We performed a retrospective analysis of women referred to an academic female pelvic medicine and reconstructive surgery practice for PFD. Data were gathered from the records of 778 women referred for pelvic floor therapy for urinary, bowel, pelvic pain, and sexual symptoms over the course of 4 years. Patients who completed at least 5 therapy sessions reported a mean symptom improvement of 80% in each of the 3 main categories analyzed, namely, urinary incontinence, defecatory dysfunction, and pelvic pain. Comprehensive, nonoperative management of PFD including pelvic floor muscle training, biofeedback, electrogalvanic stimulation, constipation management, behavioral modification, incontinence devices, and pharmacotherapy including vaginal estrogen is effective in the treatment of women with PFD.

Transforaminal pelvic fractures are high-energy injuries that are translationally and rotationally unstable. This study compared the biomechanical stability of triangular osteosynthesis vs 2-transsacral-screw fixation in the repair of a transforaminal pelvic fracture model. A transforaminal fracture model was created in 10 cadaveric lumbopelvic specimens. Five of the specimens were stabilized with triangular osteosynthesis, which consisted of unilateral L5-to-ilium lumbopelvic fixation and ipsilateral iliosacral screw fixation. The remaining 5 were stabilized with a 2-transsacral-screw fixation technique that consisted of 2 transsacral screws inserted across S1. All specimens were loaded cyclically and then loaded to failure. Translation and rotation were measured using the MicroScribe 3D digitizing system (Revware Inc, Raleigh, North Carolina). The 2-transsacral-screw group showed significantly greater stiffness than the triangular osteosynthesis group (2-transsacral-screw group, 248.7 N/mm [standard deviation, 73.9]; triangular osteosynthesis group, 125.0 N/mm [standard deviation, 66.9]; P=.02); however, ultimate load and rotational stiffness were not statistically significant. Compared with triangular osteosynthesis fixation, the use of 2 transsacral screws provides a comparable biomechanical stability profile in both translation and rotation. This newly revised 2-transsacral-screw construct offers the traumatologist an alternative method of repair for vertical shear fractures that provides biplanar stability. It also offers the advantage of percutaneous placement in either the prone or supine position. Copyright 2014, SLACK Incorporated.

To compare analgesic efficacy of preoperative versus postoperative administration of carprofen and to determine, if preincisional mepivacaine epidural anesthesia improves postoperative analgesia in dogs treated with carprofen. Blind, randomized clinical study. Dogs with femoral (n=18) or pelvic (27) fractures. Dogs were grouped by restricted randomization into 4 groups: group 1 = carprofen (4 mg/kg subcutaneously) immediately before induction of anesthesia, no epidural anesthesia; group 2 = carprofen immediately after extubation, no epidural anesthesia; group 3 = carprofen immediately before induction, mepivacaine epidural block 15 minutes before surgical incision; and group 4 = mepivacaine epidural block 15 minutes before surgical incision, carprofen after extubation. All dogs were administered carprofen (4 mg/kg, subcutaneously, once daily) for 4 days after surgery. Physiologic variables, nociceptive threshold, lameness score, pain, and sedation (numerical rating scale [NRS], visual analog scale [VAS]), plasma glucose and cortisol concentration, renal function, and hemostatic variables were measured preoperatively and at various times after surgery. Dogs with VAS pain scores >30 were administered rescue analgesia. Group 3 and 4 dogs had significantly lower pain scores and amount of rescue analgesia compared with groups 1 and 2. VAS and NRS pain scores were not significantly different among groups 1 and 2 or among groups 3 and 4. There was no treatment effect on renal function and hemostatic variables. Preoperative carprofen combined with mepivacaine epidural anesthesia had superior postoperative analgesia compared with preoperative carprofen alone. When preoperative epidural anesthesia was performed, preoperative administration of carprofen did not improve postoperative analgesia compared with postoperative administration of carprofen.

Clinical anatomy of the pelvic floor.

The study presented here comparing cross-sectional anatomy of the fetal and the adult pelvic connective tissue with the results of modern imaging techniques and actual surgical techniques shows that the classical concepts concerning the subdivision of the pelvic connective tissue and muscles need to be revised. According to clinical requirements, the subdivision of the pelvic cavity into anterior, posterior, and middle compartments is feasible. Predominating connecting tissue structures within the different compartments are: Paravisceral fat pad within the anterior compartment (Fig. 17, I), rectal adventitia or perirectal tissue within the posterior compartment (Fig. 17, II), and uterosacral ligaments within the middle compartment. The nerve-vessel guiding plate can be found in all of these compartments; it starts within the posterior compartment and it ends within the anterior one. It constitutes the morphological border between the anterior and posterior compartments in the male. This border is supplied by the uterosacral ligaments in the female. Whereas in gross anatomy no further border is discernable between anterior and posterior or middle compartment, the rectal fascia (hardly visible in embalmed cadavers) demarcates the rectal adventitia and is one of the most important pelvic structures for the surgeon. In principle, the outlined subdivision of the pelvic connective tissue is identical in the male and in the female; facts that become clear from early human life and that are already established during this period (Fig. 18). The uterus is interposed between the bladder and rectum and subdivides the pelvic peritoneum into two pouches thus establishing the only real difference between male and female pelvic cavity. The preferential direction of the pelvic connective tissue fibers is not changed by the interposition of the uterovaginal complex. The pelvic floor muscles are composed of the portions of the levator ani muscle, the muscles of the cavernous organs

Pelvic pain is a common complaint, and management of it is often difficult. We sought to evaluate the utility of magnetic resonance imaging (MRI) in the diagnosis of male pelvic pain. Though MRIs are commonly ordered to evaluate pelvic pain, there are very few studies obtaining the efficacy of pelvic MRI in determining a definitive diagnosis. The primary aim of our study was to evaluate the clinical utility of pelvic MRI for a diagnosis code that included pain. After receiving institutional review board approval, a retrospective study was performed of all pelvic MRIs completed at our institution from January 2, 2010 to December 31, 2014. These were further delineated into ordering providers by specialty and urology-specific International Classification of Diseases, Ninth Revision (ICD-9) code diagnoses (male pelvic pain, prostatitis, groin pain, scrotal pain, testicular pain, and penile pain). Clinical utility was defined as positive if MRI findings resulted in a change in management. Subanalysis was performed on patients with an ICD-9 co-diagnosis of previous oncologic concern. A total of 2,643 pelvic MRIs were ordered at our institution over a 5-year period. Of these, 597 pelvic MRIs (23%) were ordered for a diagnosis code that included pain (hip pain, rectal pain, joint pain, penile pain, scrotal pain, male pelvic pain and orchitis). Total utility for MRIs to find anatomic abnormalities potentially responsible for the present pain was 34% (205/597). When ordered by urologic providers, utility was 23%. Oncologists represented the highest positivity rate at 57%. Chronic pelvic pain is a multispecialty complaint that is difficult to treat. We were surprised to find the large number of both specialists and generalists invested in the management of pelvic pain. The increasing availability of MRI technology makes it a likely candidate to test for a clinically significant anatomic reason for pain. Though MRI is a test with minimal adverse effect and no increased risk

The sacroiliac joint is a widely described source of low back pain. Therapeutic approaches to relieve pain include the application of pelvic belts. However, the effects of pelvic belts on sacroiliac joint ligaments as potential pain generators are mostly unknown. The aim of our study was to analyze the influence of pelvic belts on ligament load by means of a computer model. Experimental computer study using a finite element method. A computer model of the human pelvis was created, comprising bones, ligaments, and cartilage. Detailed geometries, material properties of ligaments, and in-vivo pressure distribution patterns of a pelvic belt were implemented. The effects of pelvic belts on ligament strain were computed in the double-leg stance. Pelvic belts increase sacroiliac joint motion around the sagittal axis but decrease motion around the transverse axis. With pelvic belt application, most of the strained sacroiliac joint ligaments were relieved, especially the sacrospinous, sacrotuberous, and the interosseous sacroiliac ligaments. Sacroiliac joint motion and ligament strains were minute. These results agree with validation data from other studies. Assigning homogenous and linear material properties and excluding muscle forces are clear simplifications of the complex reality. Pelvic belts alter sacroiliac joint motion and provide partial relief of ligament strain that is subjectively marked, although minimal in absolute terms. These findings confirm theories that besides being mechanical stabilizers, the sacroiliac joint ligaments are likely involved in neuromuscular feedback mechanisms. The results from our computer model help with unraveling the therapeutic mechanisms of pelvic belts.

Erectile dysfunction (ED) is a common sequel of pelvic fracture urethral disruption. Those patients with nocturnal erections may respond favourably to sildenafil; however, little is known about the response to sildenafil in patients with absent nocturnal erections. The aim was to evaluate the response to the treatment of sildenafil 50 mg taken once daily in the patients with absent nocturnal erections. From January 2008 to December 2011, a total of 28 patients with absent nocturnal erections were evaluated. We recorded nocturnal penile tumescence and rigidity with an erectometer. If nocturnal erections were absent for three nights, patients were administrated sildenafil 100 mg at bedtime and tested again at the fourth night. Penile duplex ultrasound with intracavernous injection was performed to define the cause of ED. All patients received a daily dose of sildenafil 50 mg for 12 weeks. Response to sildenafil treatment was defined as sustained erections allowing vaginal penetration and intercourse. Twenty-three (78%) patients completed the daily sildenafil treatment, and follow-up was available. The nocturnal erections at the fourth night in 13 patients (46.4%) were improved. About 61.5% (8/13) reported effective response to daily sildenafil. The improvement of nocturnal erections induced by sildenafil taken at bedtime might predict the response to sildenafil taken daily. © 2016 Blackwell Verlag GmbH.

Among 684 sexually active women with pelvic inflammatory disease (PID) followed up for a mean of 35 months, we related contraceptive use to self-reported PID recurrence, chronic pelvic pain, and infertility. Persistent use of condoms during the study reduced the risk of recurrent PID, chronic pelvic pain, and infertility. Consistent condom use (about 60% of encounters) at baseline also reduced these risks, after adjustment for confounders, by 30% to 60%. Self-reported persistent and consistent condom use was associated with lower rates of PID sequelae. PMID:15284036

To compare the clinical courses of patients with pelvic fracture urethral injury (PFUI) according to initial management strategy. We reviewed the clinical courses of 63 patients with PFUI who were initially treated elsewhere and underwent delayed anastomotic urethroplasty by a single surgeon between 2008 and 2015. Patients were grouped according to their initial treatment: by suprapubic tube placement alone (49 patients, SPT group) or primary realignment (14 patients, PR group). Time to urethroplasty was defined as the period between injury and delayed urethroplasty. Clinical data regarding the status of urethral stenosis, urethroplasty procedure, and treatment outcome were analyzed. The mean time to urethroplasty in the PR group was about 3 times than that in the SPT group (133 months vs 47 months, P = .035). Fifty percent of the PR group (7 of 14) had a history of repeated urethrotomy or dilation before referral, a percentage significantly higher than that of the SPT group (20.4%, 10 of 49, P = .027). The percentage of patients having a false passage and iatrogenic scar was significantly higher in the PR group (42.9% vs 16.3%, P = .035), but there was no significant between-group difference in urethral stenosis length, operative time, operative blood loss, or the percentage of patients requiring inferior pubectomy or urethral rerouting. PR does not facilitate delayed urethroplasty, and patients who undergo PR are at high risk of having a more complicated stenosis and longer time to urethroplasty, presumably because of repeated transurethral procedures.

To investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD). Between June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed. The hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases

Pelvic floor dysfunction is defined as abnormal function of the pelvic floor and includes conditions that can have significant adverse impacts on a woman's quality of life, including urinary incontinence (stress, urge, and mixed), fecal incontinence, pelvic organ prolapse, sexual dysfunction, diastasis recti abdominis, pelvic girdle pain, and chronic pain syndromes. Women's health care providers can screen for, identify, and treat pelvic floor dysfunction. This article examines the case of a woman with multiple pelvic-floor-related problems and presents the evidence for the use of pelvic floor physical therapy (PFPT) for pregnancy-related pelvic floor dysfunction. PFPT is an evidence-based, low-risk, and minimally invasive intervention, and women's health care providers can counsel women about the role that PFPT may play in the prevention, treatment, and/or management of pelvic floor dysfunction. © 2018 by the American College of Nurse-Midwives.

Introduction and Hypothesis We evaluated the associations between pelvic floor muscle strength and tone with sexual activity and sexual function in women with pelvic floor disorders. Methods This was a secondary analysis of a multicenter study of women with pelvic floor disorders from the US and UK performed to validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR). Participants were surveyed about whether they were sexually active and completed the PISQ-IR and Female Sexual Function Index (FSFI) questionnaires to assess sexual function. Physical exams included assessment of pelvic floor strength by the Oxford Grading Scale, and assessment of pelvic floor tone per ICS guidelines. Results The cohort of 585 women was middle aged (mean age 54.9 +/−12.1) with 395 (67.5%) reporting sexual activity. Women with a strong pelvic floor (n=275) were more likely to report sexual activity than women with weak strength (n=280) (75.3 vs. 61.8%, p<0.001), but normal or hypoactive pelvic floor tone was not associated with sexual activity (68.8 vs. 60.2%, normal vs. hypoactive, p=0.08). After multivariable analysis, a strong pelvic floor remained predictive of sexual activity (OR 1.89, CI 1.18–3.03, p<0.01). Among sexually active women (n=370), a strong pelvic floor was associated with higher scores on the PISQ-IR domain of condition impact (Parameter Estimate 0.20+/−0.09, P=0.04), and FSFI orgasm domain (PE 0.51+/−0.17, P=0.004). Conclusion A strong pelvic floor is associated with higher rates of sexual activity as well as higher sexual function scores on the condition impact domain of the PISQ-IR and orgasm domain of the FSFI.

The purpose of this study was to develop a novel technique to improve the accuracy of radiographic cup anteversion measurement by correcting the influence of pelvic tilt. Ninety virtual total hip arthroplasties were simulated from computed tomography data of 6 patients with 15 predetermined cup orientations. For each simulated implantation, anteroposterior (AP) virtual pelvic radiographs were generated for 11 predetermined pelvic tilts. A linear regression model was created to capture the relationship between radiographic cup anteversion angle error measured on AP pelvic radiographs and pelvic tilt. Overall, nine hundred and ninety virtual AP pelvic radiographs were measured, and 90 linear regression models were created. Pearson's correlation analyses confirmed a strong correlation between the errors of conventional radiographic cup anteversion angle measured on AP pelvic radiographs and the magnitude of pelvic tilt (P < 0.001). The mean of 90 slopes and y-intercepts of the regression lines were -0.8 and -2.5°, which were applied as the general correction parameters for the proposed tool to correct conventional cup anteversion angle from the influence of pelvic tilt. The current method proposes to measure the pelvic tilt on a lateral radiograph, and to use it as a correction for the radiographic cup anteversion measurement on an AP pelvic radiograph. Thus, both AP and lateral pelvic radiographs are required for the measurement of pelvic posture-integrated cup anteversion. Compared with conventional radiographic cup anteversion, the errors of pelvic posture-integrated radiographic cup anteversion were reduced from 10.03 (SD = 5.13) degrees to 2.53 (SD = 1.33) degrees. Pelvic posture-integrated cup anteversion measurement improves the accuracy of radiographic cup anteversion measurement, which shows the potential of further clarifying the etiology of postoperative instability based on planar radiographs.

To analyze the available evidence regarding the effect that corticosteroids have on the prevention of fat embolism syndrome after long bone fracture of the lower limbs or pelvic fracture. In March of 2007, we performed a search of various electronic databases, including Medline, the Excerpta Medica database, the Cochrane Library, the Latin American and Caribbean Health Sciences Literature database and the Scientific Electronic Library Online. We selected randomized controlled trials that compared the effect of corticosteroids with that of placebo (or standard care) on the prevention of fat embolism syndrome after long bone fracture of the lower limbs or pelvic fracture. References from the studies included were also reviewed. Six studies were included. The pooled relative risk for developing fat embolism syndrome was 0.16 (95% CI: 0.08-0.35) in the corticosteroid group as compared with the control group. The pooled relative risk for developing hypoxemia was 0.34 (95% CI: 0.19-0.59) in the corticosteroid group as compared with the control group. The analysis of evidence showed that corticosteroids decrease the risk of developing fat embolism syndrome and hypoxemia after long bone fracture of the lower limbs.

The superior suspensory complex of the shoulder (SSCS) is a ring shaped structure composed of bones and soft tissues that play a fundamental role in the stability of the shoulder joint. Isolated injuries of the SSCS are relatively common, but injuries that affect 3 components are extremely unusual. We present a triple injury of the SSCS in a 26 year old patient with a Neer type ii clavicular fracture, a Kuhn type iii acromion fracture and an Ogawa type i coracoid fracture. An open reduction and stabilization of the clavicle was performed with 2 Kirschner nails. The acromial fracture was synthesized with 2 cannulated screws, and the coracoid fracture was treated conservatively. After 24 months of follow up the patient had an excellent functional outcome according to the Constat-Murley shoulder score and QuickDASH scoring system, and all the fractures healed correctly.

Directional asymmetry of pelvic vestiges in threespine stickleback.

Bell, Michael A; Khalef, Victoria; Travis, Matthew P

Extensive reduction of the size and complexity of the pelvic skeleton (i.e., pelvic reduction) has evolved repeatedly in Gasterosteus aculeatus. Asymmetrical pelvic vestiges tend to be larger on the left side (i.e., left biased) in populations studied previously. Loss of Pitx1 expression is associated with pelvic reduction in G. aculeatus, and pelvic reduction maps to the Pitx1 locus. Pitx1 knockouts in mice have reduced hind limbs, but the left limb is larger. Thus left-biased directional asymmetry of stickleback pelvic vestiges may indicate the involvement of Pitx1 in pelvic reduction. We examined 6,356 specimens from 27 Cook Inlet populations of G. aculeatus with extensive pelvic reduction. Samples from 20 populations exhibit the left bias in asymmetrical pelvic vestiges expected if Pitx1 is involved, and three have a slight, non-significant left bias. However, samples from three populations have a significant right bias, and one large sample from another population has equal frequencies of specimens with larger vestiges on the left or right side. A sample of fossil threespine stickleback also has significantly left-biased pelvic vestiges. These results suggest that silencing of Pitx1 or the developmental pathway in which it functions in the pelvis is the usual cause of pelvic reduction in most Cook Inlet populations of G. aculeatu, and that it caused pelvic reduction at least 10 million years ago in a stickleback population. A different developmental genetic mechanism is implicated for three populations with right-biased pelvic vestiges and for the population without directional asymmetry. (c) 2006 Wiley-Liss, Inc.

Pelvic inflammatory disease.

Soper, David E

2010-08-01

Pelvic inflammatory disease (PID) is an infection-caused inflammatory continuum from the cervix to the peritoneal cavity. Most importantly, it is associated with fallopian tube inflammation, which can lead to infertility, ectopic pregnancy, and chronic pelvic pain. The microbial etiology is linked to sexually transmitted microorganisms, including Chlamydia trachomatis, Neisseria gonorrheae, Mycoplasma genitalium, and bacterial vaginosis-associated microorganisms, predominantly anaerobes. Pelvic pain and fever are commonly absent in women with confirmed PID. Clinicians should consider milder symptoms such as abnormal vaginal discharge, metrorrhagia, postcoital bleeding, and urinary frequency as potential symptoms associated with the disease, particularly in women at risk of sexually transmitted infection. The diagnosis of PID is based on the findings of lower genital tract inflammation associated with pelvic organ tenderness. The outpatient treatment of mild-to-moderate PID should include tolerated antibiotic regimens with activity against the commonly isolated microorganisms associated with PID and usually consists of an extended spectrum cephalosporin in conjunction with either doxycycline or azithromycin. Clinically severe PID should prompt hospitalization and imaging to rule out a tuboovarian abscess. Parenteral broad-spectrum antibiotic therapy with activity against a polymicrobial flora, particularly gram-negative aerobes and anaerobes, should be implemented. Screening for and treatment of Chlamydia infection can prevent PID.

To investigate whether femoral neck fracture can be predicted retrospectively on the basis of clinical radiographs by using the combined analysis of bone geometry, textural analysis of trabecular bone, and bone mineral density (BMD). Formal ethics committee approval was obtained for the study, and all participants gave informed written consent. Pelvic radiographs and proximal femur BMD measurements were obtained in 53 women aged 79-82 years in 2006. By 2012, 10 of these patients had experienced a low-impact femoral neck fracture. A Laplacian-based semiautomatic custom algorithm was applied to the radiographs to calculate the texture parameters along the trabecular fibers in the lower neck area for all subjects. Intra- and interobserver reproducibility was calculated by using the root mean square average coefficient of variation to evaluate the robustness of the method. The best predictors of hip fracture were entropy (P = .007; reproducibility coefficient of variation < 1%), the neck-shaft angle (NSA) (P = .017), and the BMD (P = .13). For prediction of fracture, the area under the receiver operating characteristic curve was 0.753 for entropy, 0.608 for femoral neck BMD, and 0.698 for NSA. The area increased to 0.816 when entropy and NSA were combined and to 0.902 when entropy, NSA, and BMD were combined. Textural analysis of pelvic radiographs enables discrimination of patients at risk for femoral neck fracture, and our results show the potential of this conventional imaging method to yield better prediction than that achieved with dual-energy x-ray absorptiometry-based BMD. The combination of the entropy parameter with NSA and BMD can further enhance predictive accuracy. © RSNA, 2014.

Stabilization after a pelvic fracture can be accomplished using multiple techniques. The anterior external fixator has been traditionally used in variety of unstable pelvis either singly or in combination of posterior screws. These devices are cumbersome and restrict side turning and sitting particularly in obese patients. An alternative, anterior subcutaneous pelvic internal fixation technique (ASPIF) was developed which is well tolerated by patients for mobility and comfort and biomechanically more stable construct Complications of this construct included irritation of the lateral femoral cutaneous nerve, femoral nerve palsy &heterotypic ossification with reduced rates of infections and aseptic loosening as compared to external fixator. Bladder incarceration following treatment has never been reported and we encountered such a problem during management which we want to highlight.

Reconstruction of the pelvic floor with human acellular dermal matrix and omental flap following anterior pelvic exenteration.

Pelvic floor reconstruction after pelvic exenteration is challenging, particularly with bacterial contamination and/or pelvic irradiation. Traditional regional myocutaneous flap options are not always avaliable, especially in the multiply operated patient. Human acellular dermal matrix (HADM) confers several advantages and is associated with less morbidity when compared to synthetic mesh used in these compromised wound beds. We report a clinical case of an elderly patient with an anterior pelvic floor defect, who underwent successful reconstruction with a combination of human acellular dermal matrix and an omental flap.

Lee, In Sook; Choi, Euy Soon

2006-12-01

This study was conducted to investigate the effectiveness of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal delivery. The subjects of this study were 49 (experimental group: 25, control group: 24) postpartum women who passed 6 weeks after normal delivery without complication of pregnancy, delivery and postpartum. The experimental group was applied to the pelvic muscle enforcement program by biofeedback and electrical stimulation for 30 minutes per session, twice a week for 6 weeks, after then self-exercise of pelvic floor muscle was done 50-60 repetition per session, 3 times a day for 6 weeks. Maximum pressure of pelvic floor muscle contraction (MPPFMC), average pressure of pelvic floor muscle contraction (APPFMC), duration time of pelvic floor muscle contraction (DTPFMC) and the subjective lower urinary symptoms were measured by digital perineometer and Bristol Female Urinary Symptom Questionnaire and compared between two groups prior to trial, at the end of treatment and 6 weeks after treatment. The results of this study indicated that MPPFMC, APPFMC, DTPFMC were significantly increased and subjective lower urinary symptoms were significantly decreased after treatment in the experimental group than in the control group. This study suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for reinforcing pelvic floor muscle after normal delivery.

Pelvic floor interventions during pregnancy could reduce the impact of pregnancy and delivery on the pelvic floor. To determine the effects of pelvic floor interventions during pregnancy on childbirth-related and pelvic floor parameters. PubMed, Embase, and LILACS were searched for reports published during between 1990 and 2016 in English, Spanish, or Portuguese. The search terms were "pregnancy," "pelvic floor muscle training," and related terms. Randomized controlled trials with healthy pregnant women were included. Baseline and outcome data (childbirth-related parameters, pelvic floor symptoms) were compared for three interventions: EPI-NO (Tecsana, Munich, Germany) perineal dilator, pelvic floor muscle training, and perineal massage. A total of 22 trials were included. Two of three papers assessing EPI-NO showed no benefit. The largest study investigating pelvic floor muscle training reported a significant reduction in the duration of the second stage of labor (P<0.01), and this intervention also reduced the incidence of urinary incontinence (evaluated in 10 trials). Two of six trials investigating perineal massage reported that a lower rate of perineal pain was associated with this intervention. Pelvic floor muscle training and perineal massage improved childbirth-related parameters and pelvic floor symptoms, whereas EPI-NO showed no benefit. © 2018 International Federation of Gynecology and Obstetrics.

Female Pelvic Floor Biomechanics: Bridging the Gap

Purpose of review The pelvic floor is a complex assembly of connective tissues and striated muscle that simultaneously counteract gravitational forces, inertial forces, and intraabdominal pressures while maintaining the position of the pelvic organs. In 30% of women, injury or failure of the pelvic floor results in pelvic organ prolapse (POP). Surgical treatments have high recurrence rates, due, in part, to a limited understanding of physiologic loading conditions. It is critical to apply biomechanics to help elucidate how altered loading conditions of the pelvis contribute to the development of pelvic organ prolapse and to define surgeries to restore normal support. Recent findings Evidence suggests the ewe is a potential animal model for studying vaginal properties and that uterosacral and cardinal ligaments experience significant creep, which may be affecting surgical outcomes. A new method of measuring ligament displacements in vivo was developed, and finite element models that simulate urethral support, pelvic floor dynamics, and the impact of episiotomies on the pelvic floor were studied. Summary This review highlights some contributions over the past year, including mechanical testing and the creation of models, which are used to understand pelvic floor changes with loading, and the impact of surgical procedures, to illustrate how biomechanics is being utilized.

Patients who undergo pelvic floor resection as treatment for recurrent cancer following radiation therapy have increased rates of complications, particularly if permanent prosthetic mesh is used for reconstruction. Human acellular dermal matrix (HADM), commonly used for reconstruction in other torso locations, is associated with lower rates of complications (including infection, adhesions and cutaneous exposure) than synthetic mesh. We describe an effective technique to reconstruct the pelvic floor and perineum with HADM and thigh-based flaps following pelvic exenteration and radical vulvectomy. A 75-year-old woman underwent radical resection of the pelvic floor and perineum to treat recurrent vulvar squamous cell carcinoma and osteoradionecrosis. The pelvic floor and perineal soft tissue defect were reconstructed with HADM (AlloDerm; LifeCell Corporation, Branchburg, NJ) and bilateral, thigh-based tissue flaps, respectively. Despite a large resection, previous irradiation therapy and bacterial contamination the wounds healed without complications. Reconstruction of pelvic floor defects using HADM is an option when wound conditions are unfavorable for the use of permanent prosthetic meshes.

2015-10-01

We developed a three-dimensional finite element model of the pelvis. According to Letournel methods, we established a pelvis model of T-shaped fracture with its three different fixation systems, i. e. double column reconstruction plates, anterior column plate combined with posterior column screws and anterior column plate combined with quadrilateral area screws. It was found that the pelvic model was effective and could be used to simulate the mechanical behavior of the pelvis. Three fixation systems had great therapeutic effect on the T-shaped fracture. All fixation systems could increase the stiffness of the model, decrease the stress concentration level and decrease the displacement difference along the fracture line. The quadrilateral area screws, which were drilled into cortical bone, could generate beneficial effect on the T-type fracture. Therefore, the third fixation system mentioned above (i. e. the anterior column plate combined with quadrilateral area screws) has the best biomechanical stability to the T-type fracture.

Pelvic exenteration is a technically demanding surgical procedure performed for locally advanced cancers in the pelvis. Aim of the present study was to analyze morbidity, failure pattern and survival after pelvic exenteration during a period of 15 years in a dedicated cancer centre in South India. Retrospective analysis of case records of 50 patients who underwent pelvic exenteration from 1996 to 2011 in the Department of Surgical Oncology, Government Royapettah Hospital Chennai. Forty-six patients were females and 4 were males with a mean age of 48.3 years (range 21-72). Twenty six patients had cervical cancer,14 had rectal cancer, 3 had bladder cancer,2 had endometrial cancer, 2 had vaginal cancer, 1 had uterine sarcoma, 1 had anal cancer and 1 had ovarian cancer. The postoperative morbidity was 50%. 7 patients (14%) developed recurrence of which 5 had local and 2 had distant recurrence. The estimated 5 year overall survival for all patients in our series was 53.5% and for the patients with Ca rectum and Ca cervix was 60.6% and 40.1% respectively. Adjacent organ invasion had a significant impact over survival. Pelvic exenteration provides a curative form of treatment for carefully selected locally advanced cancer in the pelvis and it can be done safely with acceptable complications in centers experienced in multivisceral resections.

Anti-osteoporosis therapy and fracture healing.

PubMed

Larsson, Sune; Fazzalari, Nicola L

2014-02-01

A number of medications are approved for treatment of osteoporosis. As mode of action usually is anti-catabolic/anti-resorptive or anabolic, it is of interest to know whether these drugs affect not only normal bone remodeling, but also fracture healing. The purpose of this paper is to give a short overview of the potential effect of various anti-osteoporotic medication on fracture healing. A narrative literature review was performed to describe the current knowledge. Anti-catabolic/anti-resorptive drugs: for bisphosphonates, the most common class of drugs in this group, experimental studies have shown a larger and stronger callus and delayed remodeling but no evidence of delayed healing. A human monoclonal antibody to RANKL is another anti-catabolic drug, with the only report to date showing enhanced healing in an animal model. Strontium ranelate is a drug where both anti-catabolic and a weak anabolic effect have been proposed, with experimental data ranging from no effect to significant increase in both callus volume and strength. Anabolic drugs: PTH has demonstrated accelerated healing of various experimental fractures and of distal radius and pelvic fractures in humans. While the exact mechanism is not fully understood, PTH results in increased recruitment and differentiation of chondrocytes and enhancement of endochondral ossification. A monoclonal antibody to block sclerostin is another potential anabolic pathway, where animal data have shown increase in bone mass and strength. The potential effect on fracture healing is yet to be studied. There are still large gaps in the understanding of the potential effect of anti-osteoporotic drugs on fracture healing, although based on present knowledge a recent or present fracture should not be considered as a contraindication to such treatment.

[Purpose] Pelvic floor muscle training is a first-line therapy for female stress urinary incontinence. Previous studies have suggested that the coccyx tip moves ventrally and cranially during pelvic floor muscle contraction. The study aimed to elucidate the influence of adequate pelvic floor muscle contraction on coccyx movement. [Subjects and Methods] Sixty-three females (57 patients with stress urinary incontinence and additional 6 healthy volunteers) were enrolled. Using magnetic resonance imaging, coccyx movement was evaluated during pelvic floor muscle contraction and strain. An adequate contraction was defined as a contraction with good Oxford grading scale [≥3] and without inadequate muscle substitution patterns. [Results] Inadequate muscle substitution patterns were observed in 33 participants (52.4%). No significant difference was observed in the movement of the coccyx tip in the ventrodorsal direction between females with and without inadequate muscle substitution patterns. However, a significant increase in the movement of the coccyx tip in the cranial direction was detected in the group without inadequate muscle substitution patterns. Compared to participants with inadequate pelvic floor muscle contraction, those who had adequate pelvic floor muscle contraction exhibited significantly increased cranial movement of the coccyx. [Conclusion] Adequate pelvic floor muscle contraction can produce cranial movement of the coccyx tip.

Patients with pelvic fractures due to falls: A paradigm that contributed to autopsy-based audit of trauma in Greece

2011-01-01

Background Evaluation of the pelvic fractures (PFx) population in auditing effective components of trauma care is the subject of this study. Methods A retrospective, case-control, autopsy-based study compared a population with PFx to a control-group using a template with trauma outcome variables, which included demographics, ICD-9, intention, mechanisms, toxicology, Abbreviated Injury Scale (AIS-90), Injury Severity Score (ISS), causes of haemorrhage, comorbidity, survival time, pre-hospital response, in hospital data, location of death, and preventable deaths. Results Of 970 consecutive patients with fatal falls, 209 (21.5%) had PFx and constituted the PFx-group while 761 (78.5%) formed the control-group. Multivariate analysis showed that gender, age, intention, and height of fall were risk factors for PFx. A 300% higher odds of a psychiatric history was found in the PFx-group compared to the control-group (p < 0.001). The median ISS was 50 (17-75) for the PFx-group and 26 (1-75) for the control-group (p < 0.0001). There were no patients with an ISS less than 16 in the PFx group. Associated injuries were significantly more common in the PFx-group than in the control-group. Potentially preventable deaths (ISS < 75) constituted 78% (n = 163) of the PFx-group. The most common AIS3-5 injuries in the potentially preventable subset of patients were the lower extremities in 133 (81.6%), thorax in 130 (79.7%), abdomen/pelvic contents in 99 (60.7%), head in 95 (58.3%) and the spine in 26 (15.9%) patients. A subset of 126 (60.3%) potentially preventable deaths in the PFx-group had at least one AIS-90 code other than the PFx, denoting major haemorrhage. Deaths directly attributed to PFx were limited to 6 (2.9%). The median survival time was 30 minutes for the PFx-group and 20 hours for the control-group (p < 0.001). For a one-group increment in the ISS-groups, the survival rates over the post-traumatic time intervals were reduced by 57% (p < 0.0001). Pre-hospital mortality

Evaluation of acute pelvic pain in women.

Kruszka, Paul S; Kruszka, Stephen J

2010-07-15

Diagnosis of pelvic pain in women can be challenging because many symptoms and signs are insensitive and nonspecific. As the first priority, urgent life-threatening conditions (e.g., ectopic pregnancy, appendicitis, ruptured ovarian cyst) and fertility-threatening conditions (e.g., pelvic inflammatory disease, ovarian torsion) must be considered. A careful history focusing on pain characteristics, review of systems, and gynecologic, sexual, and social history, in addition to physical examination helps narrow the differential diagnosis. The most common urgent causes of pelvic pain are pelvic inflammatory disease, ruptured ovarian cyst, and appendicitis; however, many other diagnoses in the differential may mimic these conditions, and imaging is often needed. Transvaginal ultrasonography should be the initial imaging test because of its sensitivities across most etiologies and its lack of radiation exposure. A high index of suspicion should be maintained for pelvic inflammatory disease when other etiologies are ruled out, because the presentation is variable and the prevalence is high. Multiple studies have shown that 20 to 50 percent of women presenting with pelvic pain have pelvic inflammatory disease. Adolescents and pregnant and postpartum women require unique considerations.

The objective of the present study was to evaluate the effect of pelvic floor muscle training in 46 nulliparous pregnant women. The women were divided into 2 groups: an exercise group and a control group. Functional evaluation of the pelvic floor muscle was performed by digital vaginal palpation using the strength scale described by Ortiz and by a perineometer (with and without biofeedback). The functional evaluation of the pelvic floor muscles showed a significant increase in pelvic floor muscle strength during pregnancy in both groups (P < .001). However, the magnitude of the change was greater in the exercise group than in the control group (47.4% vs. 17.3%, P < .001). The study also showed a significant positive correlation (Spearman's test, r = 0.643; P < .001) between perineometry and digital assessment in the strength of pelvic floor muscles. Pelvic floor muscle training resulted in a significant increase in pelvic floor muscle pressure and strength during pregnancy. A significant positive correlation between functional evaluation of the pelvic floor muscle and perineometry was observed during pregnancy.

Aims A high rate of suicide has been reported in patients who sustain fractures, but the association remains uncertain in the context of other factors. The aim of this study was to examine the association between fractures and the risk of suicide in this contextual setting. Patients and Methods We performed a case-control study of patients aged 40 years or older who died by suicide between 2000 and 2011. We included patients' demographics, physical and mental health problems, and socioeconomic factors. We performed conditional logistic regression to evaluate the associations between fractures and the risk of suicide. Results We included a total of 34 794 patients who died by suicide and 139 176 control patients. We found that fractures as a homogenous group (adjusted odds ratios (aOR), 1.48; 95% confidence interval (CI) 1.43 to 1.53), and specifically pelvic (aOR 2.04; 95% CI 1.68 to 2.47) and spinal fractures (aOR 1.53; 95% CI 1.43 to 1.64), were associated with a higher risk of suicide. In addition, we found that patients who had a lower income, had never married, had lower levels of educational attainment, or had coexistent physical and mental conditions such as anxiety, mood disorders, and psychosis-related disorders had a higher risk of suicide. Conclusion Fractures, specifically those of the hip and spine, were associated with an increased risk of suicide. The findings suggest that greater clinical attention should be given to this risk in patients with fractures, especially for those with additional risk factors.

Parallel genetic origins of pelvic reduction in vertebrates

PubMed Central

Shapiro, Michael D.; Bell, Michael A.; Kingsley, David M.

2006-01-01

Despite longstanding interest in parallel evolution, little is known about the genes that control similar traits in different lineages of vertebrates. Pelvic reduction in stickleback fish (family Gasterosteidae) provides a striking example of parallel evolution in a genetically tractable system. Previous studies suggest that cis-acting regulatory changes at the Pitx1 locus control pelvic reduction in a population of threespine sticklebacks (Gasterosteus aculeatus). In this study, progeny from intergeneric crosses between pelvic-reduced threespine and ninespine (Pungitius pungitius) sticklebacks also showed severe pelvic reduction, implicating a similar genetic origin for this trait in both genera. Comparative sequencing studies in complete and pelvic-reduced Pungitius revealed no differences in the Pitx1 coding sequences, but Pitx1 expression was absent from the prospective pelvic region of larvae from pelvic-reduced parents. A much more phylogenetically distant example of pelvic reduction, loss of hindlimbs in manatees, shows a similar left–right size bias that is a morphological signature of Pitx1-mediated pelvic reduction in both sticklebacks and mice. These multiple lines of evidence suggest that changes in Pitx1 may represent a key mechanism of morphological evolution in multiple populations, species, and genera of sticklebacks, as well as in distantly related vertebrate lineages.

Prevention of childbirth injuries to the pelvic floor.

PubMed

Heit, M; Mudd, K; Culligan, P

2001-08-01

The majority of childbirth injuries to the pelvic floor occur after the first vaginal delivery. Cesarean sections performed after the onset of labor may not protect the pelvic floor. Elective cesarean section is the only true primary prevention strategy for childbirth injuries to the pelvic floor. Alternative primary prevention strategies include elective cesarean section for women with nonmodifiable risks for childbirth injuries to the pelvic floor, antepartum pelvic floor exercises, or intrapartum pudendal nerve monitoring. Secondary prevention strategies must focus on modifying obstetric practices that predispose women to pelvic floor injury. These factors are best delineated for anal incontinence and include restrictive use of episiotomy, mediolateral episiotomy when necessary, spontaneous over forceps-assisted vaginal delivery, vacuum extraction over forceps delivery, and antepartum perineal massage. Finally, tertiary prevention strategies should address the mode of delivery made for women with childbirth injuries to the pelvic floor who desire future fertility.

Objective: Defaecatory MRI allows multicompartmental assessment of defaecatory dysfunction but is often inaccessible. Integrated total pelvic floor ultrasound (transperineal, transvaginal, endoanal) may provide a cheap, portable alternative. The accuracy of total pelvic floor ultrasound for anatomical abnormalities when compared with defaecatory MRI was assessed. Methods: The dynamic images from 68 females who had undergone integrated total pelvic floor ultrasound and defaecatory MRI between 2009 and 2015 were blindly reviewed. The following were recorded: rectocoele, enterocoele, intussusception and cystocoele. Results: There were 26 rectocoeles on MRI (49 rectocoeles on ultrasound), 24 rectocoeles with intussusception on MRI (19 rectocoeles on ultrasound), 23 enterocoeles on MRI (24 enterocoeles on ultrasound) and 49 cystocoeles on MRI (35 cystocoeles on ultrasound). Sensitivity and specificity of total pelvic floor ultrasound were 81% and 33% for rectocoele, 60% and 91% for intussusception, 65% and 80% for enterocoele and 65% and 84% for cystocoele when compared with defaecatory MRI. This gave a negative-predictive value and positive-predictive value of 74% and 43% for rectocoele, 80% and 79% for intussusception, 82% and 63% for enterocoele and 48% and 91% for cystocoele. Conclusion: Integrated total pelvic floor ultrasound may serve as a screening tool for pelvic floor defaecatory dysfunction; when normal, defaecatory MRI can be avoided, as rectocoele, intussusception and enterocoele are unlikely to be present. Advances in knowledge: This is the first study to compare integrated total pelvic floor ultrasound with defaecatory MRI. The results support the use of integrated total pelvic floor ultrasound as a screening tool for defaecatory dysfunction. PMID:27730818

Pelvic floor dysfunction--does menopause duration matter?

2013-10-01

To explore the effect of menopause and hormone replacement therapy on pelvic organ prolapse and pelvic floor muscle function. The records of patients who attended a tertiary urogynaecological center were reviewed retrospectively. A standardised interview included menopausal age, i.e. years since last period or onset of menopausal symptoms, current or previous hormone use. The clinical examination included prolapse assessment (POP-Q) and palpation of the levator ani muscle. 4D transperineal ultrasound, supine and after voiding, was performed in all patients. Volume data sets were analysed for pelvic organ descent and measures of contractility and distensibility of the pelvic floor at a later date, blinded to all clinical data. Of 311 women seen during the inclusion period, 65% were postmenopausal. Current systemic or local hormone use was reported by 7% and 6%, respectively. 163 women (52%) reported prolapse symptoms with a mean bother of 5.7/10. Significant pelvic organ prolapse was found on clinical examination (POP-Q stage≥2) in 77%, and diagnosed on ultrasound in 61%. On multivariate analysis, controlling for calendaric age, parity and levator avulsion, there was no evidence for menopausal age as an independent predictor of any symptom and sign of pelvic organ prolapse and pelvic floor muscle function. Local oestrogen use and past or present hormone replacement therapy had no detectable effect on any pelvic floor parameter. Hormone deficiency following menopause is unlikely to play a major role in pelvic organ support and levator ani function. Hence, both do not appear to be substantially influenced by local or systemic hormone replacement therapy. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Treatment of acetabular fractures remains one of the most challenging tasks that orthopaedic surgeons face. An accurate assessment of the injuries and preoperative planning are essential for an excellent reduction. The purpose of this study was to evaluate the feasibility, accuracy and effectiveness of performing 3D printing technology and computer-assisted virtual surgical procedures for preoperative planning in acetabular fractures. We hypothesised that more accurate preoperative planning using 3D printing models will reduce the operation time and significantly improve the outcome of acetabular fracture repair. Ten patients with acetabular fractures were recruited prospectively and examined by CT scanning. A 3-D model of each acetabular fracture was reconstructed with MIMICS14.0 software from the DICOM file of the CT data. Bone fragments were moved and rotated to simulate fracture reduction and restore the pelvic integrity with virtual fixation. The computer-assisted 3D image of the reduced acetabula was printed for surgery simulation and plate pre-bending. The postoperative CT scan was performed to compare the consistency of the preoperative planning with the surgical implants by 3D-superimposition in MIMICS14.0, and evaluated by Matta's method. Computer-based pre-operations were precisely mimicked and consistent with the actual operations in all cases. The pre-bent fixation plates had an anatomical shape specifically fit to the individual pelvis without further bending or adjustment at the time of surgery and fracture reductions were significantly improved. Seven out of 10 patients had a displacement of fracture reduction of less than 1mm; 3 cases had a displacement of fracture reduction between 1 and 2mm.

The sacroiliac joint (SIJ) is frequently involved in low back and pelvic girdle pain. However, morphometrical and functional characteristics related to SIJ pain are poorly defined. Pelvic belts represent one treatment option, but evidence still lacks as to their pain-reducing effects and the mechanisms involved. Addressing these two issues, this case-controlled study compares morphometric, functional and clinical data in SIJ patients and healthy controls and evaluates the effects of short-term pelvic belt application. Morphometric and functional data pertaining to pelvic belt effects were compared in 17 SIJ patients and 17 controls. Lumbar spine and pelvis morphometries were obtained from 3T magnetic resonance imaging. Functional electromyography data of pelvis and leg muscles and center of pressure excursions were measured in one-leg stance. The numerical rating scale was used to evaluate immediate pain-reducing effects. Pelvic morphometry was largely unaltered in SIJ patients and also by pelvic belt application. The angle of lumbar lateral flexion was significantly larger in SIJ patients without belt application. Muscle activity and center of pressure were unaffected by SIJ pain or by belt application in one-leg stance. Nine of 17 patients reported decreased pain intensities under moderate belt application, four reported no change and four reported increased pain intensity. For the entire population investigated here, this qualitative description was not confirmed on a statistical significant level. Minute changes were observed in the alignment of the lumbar spine in the frontal plane in SIJ patients. The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application. Long-term belt effects will therefore be of prospective interest.

The decision whether or not to undergo pelvic reconstructive surgery is difficult for women suffering from pelvic organ prolapse. However, little research has examined the symptom distress and life impacts that these women face prior to this surgery. Thus, it is crucial that gynecology nurses learn about these life impacts and symptom distresses in order to help these women make the best decisions with regard to surgery. To explore the life impacts and degree of symptom distress in pre-surgery women with pelvic organ prolapse; to explore the relationships between demographic data and the variables of life impact and degree of symptom distress; and to identify the factors that relate to the explainable variance in the life impacts of these women. A cross-sectional and correlational research design was used and a total of 110 women with pelvic organ prolapse who had not yet undergone pelvic reconstruction surgery were recruited in the gynecological clinics of one medical center in Taiwan. Daytime urination frequency was the most prevalent urinary tract symptom noted by the participants; vaginal protrusion was the most prevalent pelvis-related symptom noted; and depression and anxiety were the most prevalent life impacts noted. Moreover, greater lower-urinary-tract symptom distress was associated with greater pelvic-symptom distress. Furthermore, greater lower urinary tract and pelvic symptom distresses were associated with a greater negative impact on life. Education background and pelvis-related symptoms were the explained variances in pre-surgery life impacts. Women with pelvic organ prolapse should pay particular attention to symptoms that include: daytime urinary frequency, vaginal protrusion, and emotional problems including depression and anxiety. Education background and level of symptom distress should be taken into consideration when caring for the life impacts of this vulnerable group of women.

Medicare claims are commonly used to identify hip fractures, but there is no universally accepted definition. We found that a definition using inpatient claims identified fewer fractures than a definition including outpatient and provider claims. Few additional fractures were identified by including inconsistent diagnostic and procedural codes at contiguous sites. Medicare claims data is commonly used in research studies to identify hip fractures, but there is no universally accepted definition of fracture. Our purpose was to describe potential misclassification when hip fractures are defined using Medicare Part A (inpatient) claims without considering Part B (outpatient and provider) claims and when inconsistent diagnostic and procedural codes occur at contiguous fracture sites (e.g., femoral shaft or pelvic). Participants included all long-stay nursing home residents enrolled in Medicare Parts A and B fee-for-service between 1/1/2008 and 12/31/2009 with follow-up through 12/31/2011. We compared the number of hip fractures identified using only Part A claims to (1) Part A plus Part B claims and (2) Part A and Part B claims plus discordant codes at contiguous fracture sites. Among 1,257,279 long-stay residents, 40,932 (3.2%) met the definition of hip fracture using Part A claims, and 41,687 residents (3.3%) met the definition using Part B claims. 4566 hip fractures identified using Part B claims would not have been captured using Part A claims. An additional 227 hip fractures were identified after considering contiguous fracture sites. When ascertaining hip fractures, a definition using outpatient and provider claims identified 11% more fractures than a definition with only inpatient claims. Future studies should publish their definition of fracture and specify if diagnostic codes from contiguous fracture sites were used.

Pelvic floor dysfunction is largely a complex problem of multiparous and postmenopausal women and is associated with pelvic floor or organ descent. Physical examination can underestimate the extent of the dysfunction and misdiagnose the disorders. Functional magnetic resonance (MR) imaging is emerging as a promising tool to evaluate the dynamics of the pelvic floor and use for surgical triage and operative planning. This article reviews the anatomy and pathology of pelvic floor dysfunction, typical imaging findings, and the current role of functional MR imaging. Copyright © 2013 Elsevier Inc.

Pelvic floor dysfunction, and effects of pregnancy and mode of delivery on pelvic floor.

PubMed

Bozkurt, Murat; Yumru, Ayşe Ender; Şahin, Levent

2014-12-01

Pelvic floor dysfunction (PFD), although seems to be simple, is a complex process that develops secondary to multifactorial factors. The incidence of PFD is increasing with increasing life expectancy. PFD is a term that refers to a broad range of clinical scenarios, including lower urinary tract excretory and defecation disorders, such as urinary and anal incontinence, overactive bladder, and pelvic organ prolapse, as well as sexual disorders. It is a financial burden on the health care system and disrupts women's quality of life. Strategies applied to decrease PFD are focused on the course of pregnancy, mode and management of delivery, and pelvic exercise methods. Many studies in the literature define traumatic birth, usage of forceps, length of the second stage of delivery, and sphincter damage as modifiable risk factors for PFD. Maternal age, fetal position, and fetal head circumference are nonmodifiable risk factors. Although numerous studies show that vaginal delivery affects pelvic floor structures and their functions in a negative way, there is not enough scientific evidence to recommend elective cesarean delivery in order to prevent development of PFD. PFD is a heterogeneous pathological condition, and the effects of pregnancy, vaginal delivery, cesarean delivery, and possible risk factors of PFD may be different from each other. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist; therefore, the isolated effects of these variables on the pelvic floor are difficult to study. The routine use of episiotomy for many years in order to prevent PFD is not recommended anymore; episiotomy should be used in selected cases, and the mediolateral procedures should be used if needed.

Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for

Immunological Mechanisms Underlying Chronic Pelvic Pain and Prostate Inflammation in Chronic Pelvic Pain Syndrome

2017-01-01

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common urologic morbidity in men younger than 50 years and is characterized by a diverse range of pain and inflammatory symptoms, both in type and severity, that involve the region of the pelvis, perineum, scrotum, rectum, testes, penis, and lower back. In most patients, pain is accompanied by inflammation in the absence of an invading infectious agent. Since CP/CPPS etiology is still not well established, available therapeutic options for patients are far from satisfactory for either physicians or patients. During the past two decades, chronic inflammation has been deeply explored as the cause of CP/CPPS. In this review article, we summarize the current knowledge regarding immunological mechanisms underlying chronic pelvic pain and prostate inflammation in CP/CPPS. Cumulative evidence obtained from both human disease and animal models indicate that several factors may trigger chronic inflammation in the form of autoimmunity against prostate, fostering chronic prostate recruitment of Th1 cells, and different other leukocytes, including mast cells, which might be the main actors in the consequent development of chronic pelvic pain. Thus, the local inflammatory milieu and the secretion of inflammatory mediators may induce neural sensitization leading to chronic pelvic pain development. Although scientific advances are encouraging, additional studies are urgently needed to establish the relationship between prostatitis development, mast cell recruitment to the prostate, and the precise mechanisms by which they would induce pelvic pain.

The purpose of this study is to determine whether a Pilates exercise program and a pelvic floor muscle-training (PFMT) program could provide similar improvements in pelvic muscle strength. Sixty-two women with little or no pelvic floor dysfunction were randomized to Pilates or PFMT. Each group had 24 biweekly 1-h sessions with either a physical therapist or Pilates instructor. Strength was measured via perineometry (cmH(2)O). Two questionnaires--pelvic floor distress inventory (PFDI-20) and pelvic floor impact questionnaire (PFIQ-7)--were also collected. At baseline, the Pilates and PFMT groups measured 14.9 +/- 12.5 and 12.5 +/- 10.4 cmH(2)O, respectively (p = 0.41). Both the Pilates and PFMT groups got stronger (6.2 +/- 7.5 cmH(2)O, p = 0.0002 and 6.6 +/- 7.4 cmH(2)O, p = 0.0002, respectively), with no difference between groups p = 0.85. PFIQ and PFDI scores improved from baseline but not between groups. Further study is required to determine if Pilates can actually treat pelvic floor dysfunction.

Annuloplasty with various annuloplasty ring systems is a fundamental part of mitral valve repair and has been frequently performed since its introduction by Carpentier in 1969. Due to the different advantages or disadvantages of each system, some controversies exist regarding the best type of ring annuloplasty support. Here we describe, for the first time, the case of a female patient in which a fracture of a semi-rigid open annuloplasty ring occurred, leading to annular deformation and mitral regurgitation.

Patients with pelvic ring displacement and instability can benefit from surgical reduction and instrumentation to stabilize the pelvis and improve functional outcomes. Current treatments include iliosacral screw or transsacral-transiliac screw, which provides greater biomechanical stability. However, controversy exists regarding the effects of placement of a screw across an uninjured sacroiliac joint for pelvis stabilization after trauma. Does transsacral-transiliac screw fixation of an uninjured sacroiliac joint increase pain and worsen functional outcomes at minimum 1-year followup compared with patients undergoing standard iliosacral screw fixation across the injured sacroiliac joint in patients who have sustained pelvic trauma? All patients between ages 18 and 84 years who sustained injuries to the pelvic ring (AO/OTA 61 A, B, C) who were surgically treated between 2011 and 2013 at an academic Level I trauma center were identified for selection. We included patients with unilateral sacroiliac disruption or sacral fractures treated with standard iliosacral screws across an injured hemipelvis and/or transsacral-transiliac screws placed in the posterior ring. Transsacral-transiliac screws were generally more likely to be used in patients with vertically unstable sacral injuries of the posterior ring as a result of previous reports of failures or in osteopenic patients. We excluded patients with bilateral posterior pelvic ring injuries, fixation with a device other than a screw, previous pelvic or acetabular fractures, associated acetabular fractures, and ankylosing spondylitis. Of the 110 patients who met study criteria, 53 (44%) were available for followup at least 12 months postinjury. Sixty patients were unable to be contacted by phone or mail and seven declined to participate in the study.

Intrapartum sacral stress fracture due to pregnancy-related osteoporosis: a case report.

PubMed

2013-01-01

Low back pain (LBP) and hip pain frequently occur during pregnancy and postpartum period. Although pelvic and mechanic lesions of the soft tissues are most responsible for the etiology, sacral fracture is also one of the rare causes. A 32-year-old primigravid patient presented with LBP and right hip pain which started 3 days after vaginal delivery. Although direct radiographic examination was normal, magnetic resonance imaging of the sacrum revealed sacral stress fracture. Lumbar spine and femoral bone mineral density showed osteoporosis as a risk factor. There were no other risk factors such as trauma, excessive weight gain, and strenuous physical activity. It is considered that the patient had sacral fatigue and insufficiency fracture in intrapartum period. The patient's symptoms subsided in 3 months after physical therapy and rest. In conclusion, sacral fractures during pregnancy and postpartum period, especially resulting from childbirth, are very rare. To date, there are two cases in the literature. In cases who even do not have risk factors related to vaginal delivery such as high birth weight infant and the use of forceps, exc., sacral fracture should be considered in the differential diagnosis of LBP and hip pain started soon after child birth. Pregnancy-related osteoporosis may lead to fracture during vaginal delivery.

To compare the differences in levator ani muscle biometry and hiatal dimensions between pregnant nulliparous Caucasian and East Asian women. Offline analysis of three/four-dimensional ultrasound volume data obtained from two groups of pregnant nulliparous women, Caucasian and East Asian, was performed. Volume acquisition was performed in the late third trimester using the same method in both groups, in the context of two prospective observational studies with identical entry criteria. Pelvic organ descent and levator hiatal dimensions were assessed using the volumes acquired on Valsalva maneuver, and pubovisceral muscle thickness was measured from the volumes obtained on pelvic floor muscle contraction (PFMC). Datasets of 200 East Asian and 168 Caucasian women were analyzed. Compared with Caucasian women, East Asian women had a significantly lower body mass index. All indices of pelvic organ descent were significantly higher in the Caucasian group than in the East Asian group. The difference, expressed as a percentage, in levator hiatal area on both Valsalva maneuver and PFMC was markedly greater in Caucasian (32% vs. 19%; P < 0.001) than in East Asian (24% vs. 20%; P = 0.01) women. After controlling for potential confounders using multivariate regression analysis, racial origin remained the only significant factor associated with differences in pelvic organ descent and hiatal dimensions. The thickness and area of pubovisceral muscle were significantly higher in the East Asian group. Pregnant women of East Asian racial origin have a thicker pubovisceral muscle, smaller hiatus and less mobility of pelvic organs than do pregnant Caucasian women. Copyright © 2014 ISUOG.

The human pelvic floor is a complex structure and pelvic floor dysfunction is seen frequently in females. This review focuses on the surgical reconstruction of the pelvic floor employing recent findings on functional anatomy. A selective literature research was performed by the authors. Pelvic floor activity is regulated by 3 main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor organs, bladder and rectum. A variety of symptoms can derive from pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, fecal incontinence, obstructive bowel disease syndrome and pelvic pain. These symptoms mainly derive, for different reasons, from laxity in the vagina or its supporting ligaments as a result of altered connective tissue. Pelvic floor reconstruction is nowadays driven by the concept that in case of pelvic floor symptoms, restoration of the anatomy will translate into restoration of the physiology and ultimately improve patients' symptoms. The surgical reconstruction of the anatomy is almost exclusively focused on the restoration of the lax pelvic floor ligaments. Exact preoperative identification of the anatomical lesions is necessary to allow for exact anatomical reconstruction with respect to the muscular forces of the pelvic floor. Copyright 2010 S.

The association of congenital pelvic kidney with abdominal aortoiliac aneurysm is an extremely rare clinical finding. Previous reports have described various methods of aneurysm repair with successful preservation of the function of pelvic kidney. However, to our knowledge, reconstruction of more than two renal arteries has not been established. We report a case of abdominal aortic aneurysm complicated by congenital right pelvic kidney in a 72-year-old man. Computed tomography (CT) revealed an abdominal aortic aneurysm with a maximum diameter of 54 mm and a right common iliac aneurysm of 45 mm. In addition, he had a congenital right pelvic kidney and CT angiography identified three right pelvic renal arteries. The upper artery originated from the bifurcation of the terminal aorta and the lower two originated from the right common iliac artery. Three-dimensional CT was helpful for the accurate planning of the operation. Open surgical repair of the aortoiliac aneurysm with a Dacron bifurcated graft replacement was decided and reimplantation of all three right pelvic kidney arteries to the right limb of the graft was also performed. For renal preservation, the right pelvic kidney arteries were perfused with cold Ringer's lactate using a rapid infusion pump and coronary perfusion cannula. The patient's postoperative course was uneventful, and worsening of renal function was not observed. The perfusion of renal arteries with cold Ringer's solution was thought to be a simple and appropriate procedure for renal protection.

Chronic pelvic pain is a common and debilitating problem that can significantly impair the quality of life of a woman. Patients with chronic pelvic pain are usually evaluated and treated by gynecologists, gastroenterologists, urologists, and internists. Although these patients seek medical care because they are looking for help to alleviate their pelvic discomfort and pain, in many cases the only focus is on finding and possibly treating the underlying pelvic disease.However, often the examination and work-up remain unrevealing and no specific cause of the pain can be identified. At this point patients are frequently told, that no etiology for their chronic pain syndrome can be found and that nothing can be done. In these cases it is important to recognize that pain is not only a symptom of pelvic disease, but that the patient is suffering from a chronic pelvic pain syndrome. Knowledge of the clinical characteristics of visceral pain will guide the health care provider in making a diagnosis of chronic pelvic pain and in sorting it out from the lump diagnosis of idiopathic pain. Once the diagnosis of chronic pelvic pain is made, treatment should be directed towards symptomatic pain management.This conceptualization of chronic pelvic pain is very important, because chronic pelvic pain is a treatable condition! Effective treatment modalities are available to lessen the impact of pain and offer reasonable expectations of an improved functional status.

The transrectal approach to draining deep-seated pelvic collections may be used to drain The transrectal approach to draining deep-seated pelvic collections may be used to drain intra-abdominal collections not reached by the transabdominal approach. We discuss 6 patients with such pelvic collections treated with transrectal drainage using catheter placement via Seldinger technique. Transrectal drainage helped achieve clinical and radiological resolution of pelvic collections in 6 and 5 of 6 cases, respectively. It simultaneously helped avoid injury to intervening bowel loops and neurovascular structures using real-time visualization of armamentarium used for drainage. Radiation exposure from fluoroscopic/CT guidance was avoided. Morbidity and costs incurred in surgical exploration were reduced using this much less invasive ultrasound guided transrectal catheter drainage of deep-seated pelvic collections.

Case summary A 12-year-old neutered male domestic shorthair cat was presented to our referral hospital with a chronic history of tenesmus and lumbosacral pain. A diagnosis of degenerative lumbosacral stenosis (DLSS) was made and a standard dorsal L7–S1 laminectomy was performed uneventfully, with complete recovery within 1 month. The cat was brought back 4 months later for investigation of lumbosacral pain after having suffered a minor traumatic event. Neurological examination identified a low tail carriage, weakness, exercise intolerance, left pelvic limb lameness and diminished withdrawal reflexes in both pelvic limbs with severe sacrocaudal pain. A traumatic facet fracture of the L7 articular processes and subsequent spondylolisthesis was diagnosed. A second surgery was performed to stabilise the region. The cat was normal on neurological examination 1 month later and no further clinical signs were noted. Relevance and novel information This is the first description of a fracture and spondylolisthesis as a possible postoperative complication after L7–S1 dorsal laminectomy in a cat. The case highlights the importance of postoperative changes in the supportive structures of the lumbosacral spine in cats after surgical treatment of DLSS. PMID:29552353

The aim of investigation is to improve surgical treatment of patients with locally advanced pelvic cancer. The basis of investigation is 186 patients with locally advanced pelvic cancer. The average age of patients is 65.2 ± 5.2 years (from 43.7 to 88.4 years). Among them are 112 women and 74 men. In the period from 2007 to 2015 they were carried out combined (101 patients) and expanded (85 patients) surgical intervention in the department of naval surgery of the Military medical academy after S.M.Kirov. Pelvic evisceration was performed in 63 cases. Both patients were performed isolated vascular hyperthermic chemical pelvic perfusion. Indications for plastic surgery of peritoneum pelvic were: total infralitoral pelvic evisceration (9 patients), dorsal infralitoral pelvic evisceration (11 cases) and expanded abdominoperineal rectum extirpation (34 patients). Plastic surgery with autogenouse tissues was performed to 43 patients, with reticulate explants--to 11 patients. The rate of postoperative complications was 40.2%. The rate of postoperative lethality was 8%. Expanded and combined operations of pelvic at patients with locally advanced cancer without absolute contra-indications can be performed irrespective of age. Plastic surgery of peritoneum pelvic after total and dorsal infralitoral pelvic evisceration and expanded abdominoperineal rectum extirpation indicated in all cases. The easiest method is plastic surgery with greater omentum or peritoneum pelvic. Plastic surgery with reticulate explants is performed when autoplastic is impossible.

References outside the search period were obtained selected manuscript΄s bibliography. Search terms included: pelvic anatomy, less in gynecology, single port colectomy, urological less, single port, single site, NOTES, LESS and single incision. 314 manuscripts were initially identified. Out of these, 46 manuscripts were selected based in their pelvic anatomy or surgical content; including experimental experience, clinical series and literature reviews. LESS drastically limit the surgeon's ability to perform in the operative field and the latter becomes hardened by the lack of space in anatomical location like the pelvis. Potential advantages of LESS are gained with the understanding that the surgical procedure is more technically challenging. Pelvic surgical procedures related to colorectal surgery, gynecology and urology have been performed with LESS technique and information available is mostly represented by case reports and short case series. Comparative series remain few. LESS pelvic surgery remain in its very beginning and due to the very specific anatomical conditions further development of LESS surgery in the mentioned area can be clearly be facilitated by using robotic technology. Standardization ad reproducibility of techniques are mandatory to further develop LESS in the surgical arena.. PMID:22557719

To evaluate the clinicopathologic features and predictors of pelvic metastasis in patients with germ cell tumors. Between 1990 and 2009, 2722 patients undergoing retroperitoneal lymph node dissection (RPLND) were prospectively included in our institution's testis cancer database. Patients with pelvic disease were identified and clinicopathologic features were analyzed. Of the 134 patients, 14.5% had a history of prior groin surgery. At the time of referral, 98% had received prior chemotherapy, 19.4% had undergone prior RPLND, and 24% presented as late relapse. Surgery consisted of pelvic excision alone in 37 (27.6%) and pelvic excision with primary RPLND in 2 (1.5%) or with postchemotherapy RPLND in 95 (70.9%). Median pelvic mass size was 6.5 cm. Pathology of pelvic disease revealed teratoma in 74 (55%), nonseminomatous germ cell tumor in 28 (21%), sarcoma in 8 (6%), and necrosis in 22 (16.5%). Patients with pelvic metastases had a statistically higher initial stage of presentation (P <.001) and had a higher incidence of prior groin surgeries (P <.001). Pelvic metastasis in testicular cancer is uncommon and can be a site of late relapse. These patients tend to present with high-volume retroperitoneal disease or a history of prior groin surgeries. Surgery is curative in most patients, and pelvic pathology was teratoma in more than half. Copyright © 2016 Elsevier Inc. All rights reserved.

Pelvic incidence variation among individuals: functional influence versus genetic determinism.

PubMed

Chen, Hong-Fang; Zhao, Chang-Qing

2018-03-20

Pelvic incidence has become one of the most important sagittal parameters in spinal surgery. Despite its great importance, pelvic incidence can vary from 33° to 85° in the normal population. The reasons for this great variability in pelvic incidence remain unexplored. The objective of this article is to present some possible interpretations for the great variability in pelvic incidence under both normal and pathological conditions and to further understand the determinants of pelvic incidence from the perspective of the functional requirements for bipedalism and genetic backgrounds via a literature review. We postulate that both pelvic incidence and pelvic morphology may be genetically predetermined, and a great variability in pelvic incidence may already exist even before birth. This great variability may also serve as a further reminder that the sagittal profile, bipedal locomotion mode, and genetic background of every individual are unique and specific, and clinicians should avoid making universally applying broad generalizations of pelvic incidence. Although PI is an important parameter and there are many theories behind its variability, we still do not have clear mechanistic answers.

Haptic computer-assisted patient-specific preoperative planning for orthopedic fractures surgery.

The aim of orthopedic trauma surgery is to restore the anatomy and function of displaced bone fragments to support osteosynthesis. For complex cases, including pelvic bone and multi-fragment femoral neck and distal radius fractures, preoperative planning with a CT scan is indicated. The planning consists of (1) fracture reduction-determining the locations and anatomical sites of origin of the fractured bone fragments and (2) fracture fixation-selecting and placing fixation screws and plates. The current bone fragment manipulation, hardware selection, and positioning processes based on 2D slices and a computer mouse are time-consuming and require a technician. We present a novel 3D haptic-based system for patient-specific preoperative planning of orthopedic fracture surgery based on CT scans. The system provides the surgeon with an interactive, intuitive, and comprehensive, planning tool that supports fracture reduction and fixation. Its unique features include: (1) two-hand haptic manipulation of 3D bone fragments and fixation hardware models; (2) 3D stereoscopic visualization and multiple viewing modes; (3) ligaments and pivot motion constraints to facilitate fracture reduction; (4) semiautomatic and automatic fracture reduction modes; and (5) interactive custom fixation plate creation to fit the bone morphology. We evaluate our system with two experimental studies: (1) accuracy and repeatability of manual fracture reduction and (2) accuracy of our automatic virtual bone fracture reduction method. The surgeons achieved a mean accuracy of less than 1 mm for the manual reduction and 1.8 mm (std [Formula: see text] 1.1 mm) for the automatic reduction. 3D haptic-based patient-specific preoperative planning of orthopedic fracture surgery from CT scans is useful and accurate and may have significant advantages for evaluating and planning complex fractures surgery.

[Purpose] Proper pelvic floor function is important to avoid serious dysfunctions including incontinence, prolapse, and sexual problems. The current study evaluated the knowledge of young nulliparous women about their pelvic floor and identified what additional information they wanted. [Subjects and Methods] In this cross-sectional survey, a validated, 36 item questionnaire was distributed to 212 nulliparous women. The questionnaire addressed demography, pelvic floor muscles, pelvic floor dysfunction, and possible information sources. Descriptive statistics were generated for all variables. Stability and validity testing were performed using Kappa statistics and intra class correlation coefficients to define agreement for each question. The study was approved by the ethics Committee (B300201318334). [Results] Using a VAS scale (0 to 10), the women rated their knowledge about the pelvic floor as a mean of 2.4 (SD 2.01). A total of 93% of the women were insufficiently informed and requested more information; 25% had concerns about developing urinary incontinence, and 14% about fecal incontinence. Many of the women were unaware what pelvic floor training meant. [Conclusion] There was a significant lack of knowledge about pelvic floor function among nulliparous women. The majority of nulliparous women expressed a need for education, which might offer a way to reduce dysfunction. PMID:27313364

What's new in the functional anatomy of pelvic organ prolapse?

PubMed

DeLancey, John O L

2016-10-01

Provide an evidence-based review of pelvic floor functional anatomy related to pelvic organ prolapse. Pelvic organ support depends on interactions between the levator ani muscle and pelvic connective tissues. Muscle failure exposes the vaginal wall to a pressure differential producing abnormal tension on the attachments of the pelvic organs to the pelvic sidewall. Birth-induced injury to the pubococcygeal portion of the levator ani muscle is seen in 55% of women with prolapse and 16% of women with normal support. Failure of the lateral connective tissue attachments between the uterus and vagina to the pelvic wall (cardinal, uterosacral, and paravaginal) are strongly related with prolapse (effect sizes ∼2.5) and are also highly correlated with one another (r ∼ 0.85). Small differences exist with prolapse in factors involving the vaginal wall length and width (effect sizes ∼1). The primary difference in ligament properties between women with and without prolapse is found in ligament length. Only minor differences in ligament stiffness are seen. Pelvic organ prolapse occurs because of injury to the levator ani muscles and failure of the lateral connections between the pelvic organs to the pelvic sidewall. Abnormalities of the vaginal wall fascial tissues may play a minor role.

Is pelvic pain in pregnancy a welfare complaint?

Pelvic pain in pregnancy has been suggested to be more common in Scandinavia than in the rest of the world, to be culturally specific for the region and to reflect a change in attitude among pregnant women. Little is known of the prevalence of pelvic pain in pregnancy in low-income countries. To explore whether perceived pelvic pain among pregnant women differs between affluent and poor societies. Four observational studies, comprising a total of 752 women, were carried out in circumstances ranging from wealth to poverty, focusing on the reported prevalence, location and degree of pelvic pain in pregnancy. In Uppsala, Sweden, and in Rufiji, Tanzania, the women were interviewed in late pregnancy. In Jakobstad, Finland, and in Zanzibar Town, Zanzibar, the women were approached after delivery before discharge. The reported prevalence of pelvic pain in pregnancy was 49% in Uppsala and 66% in Rufiji, 77% in Jakobstad and 81% in Zanzibar, with an overall similarity of location and degree of pain. No geographical differences were found in perceived pelvic pain among pregnant women, irrespective of the socio-economy of the countries.

Magnetic resonance imaging of pelvic endometriosis.

PubMed

Méndez Fernández, R; Barrera Ortega, J

Endometriosis is common in women of reproductive age; it can cause pelvic pain and infertility. It is important to diagnose endometriosis and to thoroughly evaluate its extension, especially when surgical treatment is being considered. Magnetic resonance imaging (MRI) with careful examination technique and interpretation enables more accurate and complete diagnosis and staging than ultrasonography, especially in cases of deep pelvic endometriosis. Furthermore, MRI can identify implants in sites that can be difficult to access in endoscopic or laparoscopic explorations. In this article, we describe the appropriate MRI protocol for the study of pelvic endometriosis and the MRI signs of pelvic organ involvement. It is necessary to know the subtle findings and to look for them so we can ensure that they are not overlooked. We describe clinical grading systems for endometriosis and review the diagnostic efficacy of MRI in comparison with other imaging techniques and surgery. Copyright © 2017 SERAM.

[Purpose] The purpose of this study was to compare changes in the mobility of the pelvic floor muscle during the abdominal drawing-in maneuver, maximal expiration, and pelvic floor muscle maximal contraction. [Subjects] Thirty healthy adults participated in this study (15 men and 15 women). [Methods] All participants performed a bridge exercise and abdominal curl-up during the abdominal drawing-in maneuver, maximal expiration, and pelvic floor muscle maximal contraction. Pelvic floor mobility was evaluated as the distance from the bladder base using ultrasound. [Results] According to exercise method, bridge exercise and abdominal curl-ups led to significantly different pelvic floor mobility. The pelvic floor muscle was elevated during the abdominal drawing-in maneuver and descended during maximal expiration. Finally, pelvic floor muscle mobility was greater during abdominal curl-up than during the bridge exercise. [Conclusion] According to these results, the abdominal drawing-in maneuver induced pelvic floor muscle contraction, and pelvic floor muscle contraction was greater during the abdominal curl-up than during the bridge exercise.

Motor cortical representation of the pelvic floor muscles.

Pelvic floor muscle training involves rhythmical voluntary contractions of the external urethral sphincter and ancillary pelvic floor muscles. The representation of these muscles in the motor cortex has not been located precisely and unambiguously. We used functional magnetic resonance imaging to determine brain activity during slow and fast pelvic floor contractions. Cerebral responses were recorded in 17 healthy male volunteers, 21 to 47 years old, with normal bladder control. Functional magnetic resonance imaging was performed during metronome paced slow (0.25 Hertz) and fast (0.7 Hertz) contractions of the pelvic floor that mimicked the interruption of voiding. To study the somatotopy of the cortical representations, flexion-extension movements of the right toes were performed as a control task. Functional magnetic resonance imaging during pelvic floor contractions detected activity of the supplementary motor area in the medial wall and of the midcingulate cortex, insula, posterior parietal cortex, putamen, thalamus, cerebellar vermis and upper ventral pons. There were no significant differences in activation between slow and fast contractions. Toe movements involved significantly stronger activity of the paracentral lobule (ie the medial primary motor cortex) than did the pelvic floor contractions. Otherwise the areas active during pelvic floor and leg muscle contractions overlapped considerably. The motor cortical representation of pelvic floor muscles is located mostly in the supplementary motor area. It extends further ventrally and anteriorly than the representation of distal leg muscles.

Female Pelvic Vein Embolization: Indications, Techniques, and Outcomes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lopez, Anthony James, E-mail: consultant@radiologist.co.uk

Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequatemore » randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.« less

Fibromyalgia (FM) patients were recently found to have more symptom burden from bothersome pelvic pain syndromes that women seeking care for pelvic floor disease at a urogynecology clinic. We sought to further characterize pelvic floor symptoms in a larger sample of FM patients using of validated questionnaires. Female listserv members of the Fibromyalgia Information Foundation completed an online survey of three validated questionnaires: the Pelvic Floor Distress Inventory 20 (PFDI-20), the Pelvic Pain, Urgency and Frequency Questionnaire (PUF), and the Revised Fibromyalgia Impact Questionnaire (FIQR). Scores were characterized using descriptive statistics. Patients (n = 204 with complete data on 177) were on average 52.3 ± 11.4 years with a mean parity of 2.5 ± 1.9. FM severity based on FIQR score (57.2 ± 14.9) positively correlated with PFDI-20 total 159.08 ± 55.2 (r = .34, p <.001) and PUF total 16.54 ± 7 (r = .36, p <.001). Women with FM report significantly bothersome pelvic floor and urinary symptoms. Fibromyalgia management should include evaluation and treatment of pelvic floor disorders recognizing that pelvic distress and urinary symptoms are associated with more severe FM symptoms. Validated questionnaires, like the ones used in this study, are easily incorporated into clinical practice. PMID:26259883

2015-08-01

Bilateral non traumatic femoral neck fatigue fracture is a rare condition usually occurring secondary to medical conditions such as pregnancy, pelvic irradiation, corticosteroid exposure, chronic renal failure and osteomalacia. In this report, we present three young female patients with bilateral femoral neck fracture secondary to osteomalacia. The underlying cause of osteomalacia was Celiac disease in all patients. The patients were treated with closed reduction and internal fixation with cannulated lag screws. They were free of pain and full weight bearing was achieved at three months. There were no complications, avascular necrosis and nonunion during the follow up period. In patients with bone pain, non traumatic fractures and muscle weakness, osteomalacia should be kept in mind and proper diagnostic work-up should be performed to identify the underlying cause of osteomalacia such as celiac disease.

2015-04-01

The aim of this paper was to describe the operative details for en bloc removal of the adnexal tumor, uterus, pelvic peritoneum, and rectosigmoid colon with colorectal anastomosis in advanced epithelial ovarian cancer patients with widespread pelvic involvement. The patient presented with good performance status and huge pelvic tumor extensively infiltrating into adjacent pelvic organs and obliterating the cul-de-sac. The patient underwent en bloc pelvic resection as primary cytoreductive surgery. En bloc pelvic resection procedure is initiated by carrying a circumscribing peritoneal incision to include all pan-pelvic disease within this incision. After retroperitoneal pelvic dissection, the round ligaments and infundibulopelvic ligaments are divided. The ureters are dissected and mobilized from the peritoneum. After dissecting off the anterior pelvic peritoneum overlying the bladder with its tumor nodules, the bladder is mobilized caudally and the vesicovaginal space is developed. The uterine vessels are divided at the level of the ureters, and the paracervical tissues (or parametria) are divided. The proximal sigmoid colon is divided above the most proximal extent of gross tumor using a ligating and dividing stapling device. The sigmoid mesentery is ligated and divided including the superior rectal vessels. The pararectal and retrorectal spaces are further developed and dissected down to the level of the pelvic floor. The posterior dissection is progressed and moves to the right and then to the left of the rectum. The rectal pillars including the middle rectal vessels are ligated and divided. Hysterectomy is completed in a retrograde fashion. The distal rectum is divided using a linear stapler. The specimen is removed en bloc with the uterus, adnexa, pelvic peritoneum, rectosigmoid colon, and tumor masses leaving a macroscopically tumor-free pelvis. Colorectal anastomosis was completed using stapling device. En bloc pelvic resection was performed by total

Acetabular fractures potentially account for up to half of all pelvic fractures, while pelvic fractures potentially account for over one-tenth of all human bone fractures. This is the first biomechanical study to assess acetabular fracture fixation using plates versus cables in the presence of a total hip arthroplasty, as done for the elderly. In Phase 1, finite element (FE) models compared a standard plate method versus 3 cable methods for repairing an acetabular fracture (type: anterior column plus posterior hemi-transverse) subjected to a physiological-type compressive load of 2207N representing 3 x body weight for a 75kg person during walking. FE stress maps were compared to choose the most mechanically stable cable method, i.e. lowest peak bone stress. In Phase 2, mechanical tests were then done in artificial hemipelvises to compare the standard plate method versus the optimal cable method selected from Phase 1. FE analysis results showed peak bone stresses of 255MPa (Plate method), 205MPa (Mears cable method), 250MPa (Kang cable method), and 181MPa (Mouhsine cable method). Mechanical tests then showed that the Plate method versus the Mouhsine cable method selected from Phase 1 had higher stiffness (662versus 385N/mm, p=0.001), strength (3210versus 2060N, p=0.009), and failure energy (8.8versus 6.2J, p=0.002), whilst they were statistically equivalent for interfragmentary sliding (p≥0.179) and interfragmentary gapping (p≥0.08). The Plate method had superior mechanical properties, but the Mouhsine cable method may be a reasonable alternative if osteoporosis prevents good screw thread interdigitation during plating.

Minimally invasive tension band wiring technique for olecranon fractures.

PubMed

Takada, Naoya; Kato, Kenji; Fukuta, Makoto; Wada, Ikuo; Otsuka, Takanobu

2013-12-01

Some types of implants, such as plates, screws, wires, and nails, have been used for open reduction and internal fixation of olecranon fractures. A ≥ 10 cm longitudinal incision is used for open reduction and internal fixation of olecranon fractures. According to previous studies, tension band wiring is a popular method that gives good results. However, back out of the wires after the surgery is one of the main postoperative complications. Moreover, if the Kirschner wires are inserted through the anterior ulnar cortex, they may impinge on the radial neck, supinator muscle, or biceps tendon. Herein, we describe the minimally invasive tension band wiring technique using Ring-Pin. This technique can be performed through a 2 cm incision. Small skin incisions are advantageous from an esthetic viewpoint. Ring-Pin was fixed by using a dedicated cable wire that does not back out unless the cable wire breaks or slips out of the dedicated metallic clamp. As the pins are placed in intramedullary canal, this technique does not lead to postoperative complications that may occur after transcortical fixation by conventional tension band wiring. Minimally invasive tension band wiring is one of the useful options for the treatment of olecranon fractures with some advantages.

Provide guidelines for clinical practice concerning postpartum rehabilitation. Systematically review of the literature concerning postpartum pelvic floor muscle training and abdominal rehabilitation. Pelvic-floor rehabilitation using pelvic floor muscle contraction exercises is recommended to treat persistent urinary incontinence at 3 months postpartum (grade A), regardless of the type of incontinence. At least 3 guided sessions with a therapist is recommended, associated with pelvic floor muscle exercises at home. This postpartum rehabilitation improves short-term urinary incontinence (1 year) but not long-term (6-12 years). Early pelvic-floor rehabilitation (within 2 months following childbirth) is not recommended (grade C). Postpartum pelvic-floor rehabilitation in women presenting with anal incontinence, is associated with a lower prevalence of anal incontinence symptoms in short-term (1 year) (EL3) but not long-term (6 and 12) (EL3). Postpartum pelvic-floor rehabilitation is recommended to treat anal incontinence (grade C) but results are not maintained in medium or long term. No randomized trials have evaluated the pelvic-floor rehabilitation in asymptomatic women in order to prevent urinary or anal incontinence in medium or long term. It is therefore not recommended (expert consensus). Rehabilitation supervised by a therapist (physiotherapist or midwife) is not associated with better results than simple advice for voluntary contraction of the pelvic floor muscles to prevent/correct, in short term (6 months), a persistent prolapse 6 weeks postpartum (EL2), whether or not with a levator ani avulsion (EL3). Postpartum pelvic-floor rehabilitation is not associated with a decrease in the prevalence of dyspareunia at 1-year follow-up (EL3). Postpartum pelvic-floor rehabilitation guided by a therapist is therefore not recommended to treat or prevent prolapse (grade C) or dyspareunia (grade C). No randomized trials have evaluated the effect of pelvic
