The aim of this study was to describe the nature and incidence of hand injuries caused by snowblowers, as well as the accident conditions and accident prevention. We conducted a retrospective evaluation over ten consecutive winters. Nine patients were included. All were men with an average age of 49.7 years (17-71). The accidents occurred at home in seven out of nine patients. The machine was running in 50% of the injury events. In most cases, the injuries occurred when the patient tried to unclog snow from the lateral discharge chute. Only four out of the nine patients had read the instructions or received instructions from the salesperson. The dominant hand was injured in 7 out of 9 patients. An average of 2.7 fingers were injured. The longest fingers were most commonly injured: 8 middle fingers, 7 ring fingers, 4 little fingers, 2 indexes and 1 thumb. All the fractures were open. Three patients were operated on several times. In 7 out of 9 cases, the patients had sequelae such as amputation. The mean time off work was 11.4 weeks (3-24). All the patients were experienced snowblower users (9 years and 57th use on average). Snowblower accidents are very mutilating. Prevention must include protected access to blades and better verbal and written safety warnings. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Experiences and consequences for women with hand-arm vibration injuries.

PubMed

Bylund, Sonya Hörnqwist; Ahlgren, Christina

2010-01-01

Vibrating machines are used in a variety of occupations. Exposure to hand-arm vibration can cause vascular, neurological, and muscular symptoms in the hands and arms. This qualitative study provides a deeper understanding of the consequences of vibration injuries in women. In depth interviews were conducted with eight women with vibration injuries. The women were metal and wood product assemblers and dental personnel. The transcribed interviews were analyzed in accordance with the grounded theory method. The core category in the findings was "another life". This was constructed by the categories "consequences for everyday activities", "work performance", "household duties", "leisure", and "self perception" and shows that the injury had affected most parts of the women's lives and decreased their quality of life. The importance of well-functioning hands in all activities was highlighted. Reduced hand function due to numbness, muscle weakness, and pain caused restricted abilities to perform activities at work, at home, and during leisure time. The women described impact on their self-perception, as the injury had affected them in their roles as a worker, mother, and woman. The findings indicate that a vibration injury is a multidimensional problem that can affect every aspect of an individual's life. Health care providers should be aware of these complex consequences.

Hand injuries can result in significant time away from competition for professional basketball players. Time to return to play after hand injuries in elite athletes has not been well described. To report the return to play from metacarpal fractures, phalangeal fractures, and thumb ligament tears in National Basketball Association (NBA) players over a 5-year period. Descriptive epidemiology study. The NBA transaction report was analyzed from January 2009 to May 2014. Players were identified if they were added to the inactive list (IL), missed games due to their injury, or underwent surgery as a result of hand injury. Number of games missed due to injury, days spent on the IL, and age at injury were calculated by injury type and location. One hundred thirty-seven injuries were identified: 39 injuries to the hand and 98 injuries to the finger. Three major injury patterns were identified and analyzed: metacarpal fractures (n = 26), phalangeal fractures (n = 33), and thumb ligament tears (n = 9). The type of injury sustained affected return to play ( P < .05). All thumb ligament tears required surgery and had the longest return to play of 67.5 ± 17.7 days ( P < .05). The return to play for surgically treated metacarpal fractures (56.7 ± 26.3 days) was significantly greater than nonsurgically treated metacarpal fractures (26.3 ± 12.1 days; P < .01). Return to play for surgically repaired phalangeal fractures (46.2 ± 10.8 days) trended greater but was not significantly different than phalangeal fractures treated nonsurgically (33.3 ± 28.5 days; P = .21). Hand injuries in professional basketball players can lead to prolonged periods of time away from competition, especially after surgery. This study provides guidelines on expected return to play in the NBA after these common hand injuries.

The management of hand injuries caused by sea urchin spines.

PubMed

Nassab, R; Rayatt, S; Peart, F

2005-08-01

Injuries to the hand by sea urchin spines are not commonly seen in the United Kingdom. There are many varieties of sea urchins (Echinoidea) throughout the world. They have a spherical calcium carbonate exoskeleton covered with spines. Certain varieties may be venomous, in particular the flower urchin (Toxopneustes pileolus) found in the Indo-Pacific oceans. Injury may also be caused by the urchin spines or pedicellaria (delicate seizing organs equipped with jaws). A small number of hand injuries associated with sea urchin spines have been reported in the literature.

Injuries of the hand can cause significant functional impairment, diminished quality of life and delayed return to work. However, the incidence and functional outcome of hand injuries in polytrauma patients is currently unknown. The aim of this study was to determine the incidence, distribution and functional outcome of fractures and dislocation of the hand in polytrauma patients. A single centre retrospective cohort study was performed at a level 1 trauma centre. Polytrauma was defined as patients with an Injury Severity Score of 16 or higher. Fractures and dislocations to the hand were determined. All eligible polytrauma patients with hand injuries were included and a Quick Disability of Arm, Shoulder and Hand questionnaire (QDASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) were administered. Patients were contacted 1-6 years after trauma. In a cohort of 2046 polytrauma patients 72 patients (3.5%) suffered a hand injury. The functional outcome scores of 52 patients (72%) were obtained. The Metacarpal (48%) and carpal (33%) bones were the most frequently affected. The median QDASH score for all patients with hand injury was 17 (IQR 0-31) and the PRWHE 14 (IQR 0-41). Patients with a concomitant upper extremity injury (p=0.002 for PRWHE, p0.006 for QDASH) and those with higher ISS scores (p=0.034 for PRWHE, QDASH not significant) had worse functional outcome scores. As an example, of the 5 patients with the worst outcome scores 3 suffered an isolated phalangeal injury, all had concomitant upper extremity injury or neurological injuries (3 plexus injuries, 1 severe brain injury). The incidence of hand injuries in polytrauma patients is 3.5%, which is relatively low compared to a general trauma population. Metacarpal and carpal bones were most frequently affected. The functional extremity specific outcome scores are highly influenced by concomitant injuries (upper extremity injuries, neurological injuries and higher ISS). Copyright © 2017 Elsevier Ltd. All

The exploded hand syndrome: a report of five industrial injury cases.

PubMed

Al-Qattan, M M

2013-10-01

The term 'exploded hand syndrome' refers to a specific type of crush injury to the hand in which a high compressive force excessively flattens the hand leading to thenar muscle extrusion through burst lacerations. Out of 89 crushed hands seen over a period of seven years, only five had exploded hand syndrome. They were all male industrial workers ranging in age between 24 and 55 years. All patients had thenar muscle extrusion. Other concurrent injuries included fractures/dislocations, compartment syndrome, and ischaemia. All patients were treated by excision of the extruded intrinsic muscles, as well as primary management of concurrent injuries. All patients had functional assessment including: motor power and sensory testing, range of motion of hand joints, and the quick DASH score. Objective testing showed reduced sensibility in the thumb, reduced grip strength (mean 52% of contralateral hand), reduced pinch strength (mean of 27% of contralateral hand), reduced thumb opposition (the mean Kapandji Score was 5 out of 10), and deficits in the range of motion of the metacarpophalangeal and interphalangeal joints of the thumb. The quick DASH score ranged from 11 to 49 and only two patients were able to go back to regular manual work.

Injuries during cultivation of land are the significant causes of recession for an agricultural country like Bangladesh. Thousands of tools are used in agricultural farm having much probability of getting injury at their workplaces. For the injury prevention, proper hand tool designs need to be recommended with ergonomic evaluations. This paper represents the main causes of agricultural injuries among the Bangladeshi farmers. Effective interventions had been discussed in this paper to reduce the rate of injury. This study was carried out in the Panchagarh district of Bangladesh. Data on 434 agricultural injuries were collected and recorded. About 67% injuries of all incidents were due to hand tools, and the remaining 33% were due to machinery or other sources. Though most of the injuries were not serious, about 22% injuries were greater than or equal to AIS 2 (Abbreviated Injury Scale). The practical implication of this study is to design ergonomically fit agricultural hand tools for Bangladeshi farmers in order to avoid their injuries.

Recreational mountain biking continues to increase in popularity and is a significant source of traumatic injury, including injuries to the hand and wrist. A prospective survey of all hand and wrist injuries sustained while participating in recreational mountain biking presenting to the emergency department at the Municipality of Whistler and the District of Squamish was conducted over a 12-month consecutive period. An analysis of 765 unique emergency department visits with 1,079 distinct injuries was performed. Of these injuries, 511 were sustained to the upper limb. Injury to the metacarpal and metacarpal phalangeal joints was the most common hand injury (52) followed by proximal phalanx and proximal interphalangeal joint (20). Mountain biking is a frequent source of a variety of upper limb trauma, and preventative efforts are necessary to minimize the burden of these injuries.

The hands of "blast" resulting from the handling of unstable explosives. Their repercussion is functional and vital in trauma patients. The authors report their experience of care from the hands of blast in precarious health situation. Between 2001 and 2012, 33 hand blasts were supported in 30 injured civilians and military, received emergency, during and after armed conflict. Two women (6.7%) and 28 men (93.3%) were received, including four teenagers (13.3%) and 26 adults (86.7%). During the war, 15 officers weapon (50%) and three civilians (10%) underwent surgery, or 60% of hand injuries. In peacetime, civilians were mostly operated in 33.3% of cases, against 6.7% of cases of agents' weapon. Nineteen hands blast (57.6%) were observed during the war and 14 in peacetime, or 42.4% of cases. The average age was 25.2 years, with extremes of 12 and 50 years. Thirteen left hands (39.4%) and 20 right hands (60.6%) were operated. The lesion concerned all the anatomical structures of the hand. It was unilateral in 27 cases (81.9%) and bilateral in three cases (9.1%). Three types of hand trauma were observed and were as follows: trauma patients with injuries of the hand (18.2%), trauma of severe and isolated proximal hand or finger amputations (75.7%), and trauma of the hand without apparent seriousness (6.1%). The associated lesion was eye (one case), chest (one case), abdominal (five cases). Debridement was performed immediate emergency (93.9%) and delayed (6.1%). The treatment was surgical hemostasis, made mainly of amputations (69.7%) and regularization of digital stumps (12.1%). The repair was performed in 18.2% of cases. One death has been reported in a polytrauma patient with chest blast. Blast injuries of the hand are common in times of war in armed agents. The young people, manual workers and children are paying a heavy price in peacetime. As land mines which affect feet, instable hand grenades are left exposed in nature.

Agricultural injuries to the hand and upper extremity.

PubMed

Yaffe, Mark Aaron; Kaplan, F Thomas

2014-10-01

Agricultural injuries involving the hand and upper extremity are common, debilitating injuries that reflect the significant occupational hazards associated with the agricultural industry. Farm injuries occur in all age groups and are associated with significant resource utilization and treatment costs. Most of these injuries are associated with machinery, including tractors, power take-off devices, grain augers, hay balers, and combine harvesters. Each piece of machinery produces specific injury patterns and a spectrum of bone and soft-tissue injuries that are frequently characterized by the loss of a digit or limb, permanent disability, loss of function, and serious complications such as infection. Management of agricultural injuries includes expedient administration of antibiotic and tetanus prophylaxis, aggressive irrigation, serial débridement, consideration of delayed wound closure, and reconstruction or replantation of amputated digits and limbs, if feasible.

Akşam, Berrak; Akşam, Ersin; Ceran, Candemir; Demirseren, Mustafa Erol

2016-01-01

The purpose of this study was to describe the role of public exercise equipment in pediatric hand traumas as a preventable etiological factor. Pediatric patients with hand injuries referred from the emergency department were evaluated retrospectively. Age and gender of the patients, timing, etiology, mechanism of hand trauma, localization of the injury, diagnoses of the patients, and hospitalization rates were reviewed. Amongst the 310 pediatric patients evaluated, 31 patients (10%) experienced injury related to public exercise equipment. Within this group of patients, most were between 5 to 9 years of age, and all injuries were blunt and crush type. Lacerations and fractures were the main diagnoses. Complex injuries that required inpatient care were reported in 19.3% of the patients. Public exercise equipment-related injuries are increasingly prevalent in pediatric hand traumas. Preventive actions such as shielding the moving parts should be taken to reduce these rates.

Extensor Tendon Injuries and Repairs in the Hand

PubMed Central

Kontor, J. A.

1982-01-01

Due to their superficial course, the extensor tendons are frequently lacerated over the dorsum of the hand and fingers. Excellent functional results are obtained in repairs of simple tendon lacerations. ‘Open’ mallet lacerations over the distal IP joint or involving the central extensor slip over the proximal IP joint require more precise suturing methods. More proximal extensor tendon divisions near the wrist involve dissection of the retracted finger extensors or long thumb extensor in the distal forearm and more formal tendon repairs, including a possible tendon transfer to the thumb. ‘Closed injuries’, with varying degrees of extensor tendon disruption, occur at three main sites. The mallet injury at the DIP joint and the boutonnière deformity over the PIP joint are sometimes recognized late, but respond to conservative splinting for a minimum of four weeks with guarded motion avoiding secondary stiffening of the remaining small joints of the hand. Surgery of closed injuries most frequently involves the intra-articular traction fracture type of mallet deformities in which the DIP joint has taken the brunt of the injury. PMID:21286174

2009-01-01

Injuries from electric saws cause considerable hand trauma. This study is designed to provide information detailing the costs of these injuries. The study was performed in a tertiary referral academic medical center. The records of patients injured by electric table saws were reviewed. Information regarding demographics, injury severity, medical expense, and time lost from work was analyzed. The patients were stratified by injury severity for further analysis. The mean wage for the region was used to estimate costs of time away from work. The Consumer Protection Agency's review was used to estimate the nationwide burden of these injuries. The study group included 134 patients. Of these patients, 126 were male and 8 were female. The dominant hand was injured in 20; the nondominant, in 114. The mean age was 47.0 years. The mean time lost from work was 64 days. The mean cost of medical expenses for all patients was $22,086, with $8,668 in lost wages, for a total of $30,754 mean cost per injury. The total economic burden for the injuries in this study is $4,121,097. These injuries represent a spectrum of severity, with minor injuries incurring lower hospital fees and requiring less time off work as compared to more involved injuries. Electric saws cause a wide spectrum of injuries that result in not only tremendous physical and emotional pain but also substantial economic impact as well. Technologies that would prevent such injuries would be a socioeconomic advancement. Federal mandates to implement such technologies should be encouraged.

Hand injury with a nail gun: a case report with literature review.

PubMed

Boya, Hakan; Uzun, Belkan

2015-01-01

The nail gun was introduced in the late 1950s to increase the ease of driving nails, studs, bolts, or staples into various hard surfaces. The nail gun is a potentially dangerous device that is still commonly used in the construction industry. Since its introduction, an increasing number of studies have reported injuries associated with nail guns. Nail gun-related injuries-such as to the head, neck, and chest-can be devastating, and in some cases, even fatal. Extremity injuries, notably in the hand, can cause loss of function, missed work, and long-term health effects. This case report describes a nail-gun injury of the hand along with a discussion of the unique features of and treatment strategies for nail gun injuries.

Recognition of factitial hand injuries.

PubMed

Carlson, M J; Linscheid, R L; Lucas, A R

1977-01-01

Facitial injuries with various presentations occur with some frequency to the hand because it is a body part that is easily accessible. Methods used to produce wounds included insertion of porcupine quills, application of constrictive rubber bands, mascara injections and excoriation of healing wounds. It is important to recognize the factitial origin in order to avoid needless repetitive surgery and permanent hand disability. No specific pattern of psychopathology was found in our cases. The patients' attitude toward their lesions was one of bland unconcern and stoicism. The patients were resistant to psychiatric referral and persisted in seeking medical responsibility for cure. Successful management requires early suspicion and prompt recognition as well as establishment of non-accusatory relationship with the primary physician. Confrontation should be avoided if possible. Even if reinforced with collaborative evidence, such confrontation will have limited effect on the patient's subsequent behavior.

To assess the association of four techniques used in management of second stage with risk of moderate and severe perineal injury. Retrospective cross-sectional study. A metropolitan maternity hospital and a private maternity hospital in Brisbane, Australia. Term women with singleton, cephalic presentation experiencing a non-operative vaginal birth from January 2011 to December 2016. The research sites perinatal database recorded data on clinicians approach to instructing women during second stage and hand position at birth. Women were identified from matching the inclusion criteria (n = 26,393) then grouped based on combinations of hands-on, hand- poised, directed and undirected pushing. The associations with perineal injury were estimated using odds ratios obtained by multivariate analysis. Primary outcomes were the risk of moderate and severe perineal injury. The significance was set at 0.001. In Nulliparous women there was no difference in the risk of moderate or severe perineal injury between the different techniques. In multiparous women the use of a hands-on/directed approach was associated with a significant increase in the risk of moderate (AOR 1.18, 95% CI 1.10-1.27, p < 0.001) and severe perineal injury (AOR 1.50, 95% CI 1.20-1.88, p < 0.001) compared to hands-poised/undirected. A hands poised/undirected approach could be utilised in strategies for the prevention of moderate and severe perineal injury. Copyright © 2018 Elsevier Ltd. All rights reserved.

2000-01-01

High-pressure injection injuries of the hand have a reputation for being dangerous for individual fingers and even for whole hand. Usually appearing innocuous at presentation because of small puncture entry wound, these injuries result in severe damage of most internal structures in finger and hand due to extensive penetration of injected substance. This paper reviews the outcome of the treatment of such injuries in 10 patients: 9 sustained injection of toxic paint, and one lead shot. All the patients were operated on: eight a few hours after injury and two with 3 days delay. The surgical technique included wide exposure from site of injection up to the farthest place in which foreign substance was seen. Thorough debridment of injected material and contaminated tissue was performed with careful preservation of neurovascular structures and tendons. Wounds were not closed, but managed by open technique. In all patients wounds healed well: in 3 by secondary intention, in 6 by delayed closure and 2 were covered by skin grafts. No amputation was performed. Final results were assessed form 1.5 to 3.5 years after initial injury (mean at 2.5 years). Two patients complained of moderate pain related to the weather, five of cold intolerance and two of impaired sensation on fingertips. Active range of motion of affected fingers was in whole group from 90% to 104% (mean 97%) of the range of motion of unaffected fingers from the other side. Range of motion of the wrist (2 patients) was 76% and 117% of range of motion of the other side. Pinch grip strength was from 81% to 116% (mean 99%), and global grip strength from 77% to 119% (mean 97%) of the other side. All patients went back to their previous jobs and periods of sick leave were from 2 weeks to 6 months (mean 3 mo). Excellent results achieved in this study--full functional recovery in 9 of 10 patients confirm the effectiveness of aggressive treatment by open wound technique of such injuries.

Fireworks or firecrackers can cause serious accidents. They are classified from K1 to K4 according to the amount of powder they contain. In Alsace (France), a type-K1 firecracker is available on the free market and the K2 and K3 ones are prohibited. The aim of this study was to reveal the effects of measures taken in order to prevent repercussions related to hand injuries caused by fireworks. Patients who fell victim to firework incidents have been recorded since 2006, starting date of the prevention campaign. Records have been taken on the circumstances, the group of firecracker, the level of injury and the severity of the injury in four stages. Our series included 62 hands from 58 patients (average age: 25 years), including two women. Most of them sustained their injury during the night of New Year's Eve. The study dealt with 21 K1, and 35 K2 or K3. We registered 29 cases of grade I, 2 grades II, 21 grades III and 9 grades IV. One patient died. The numbers of consultations, K2/K3 injuries and number of surgeries increased from 2006 to 2012. Our results show that firework-related injuries to the hand are serious, pluridigital, multistage and/or bilateral. Prevention was ineffective but should be improved and strengthened, as a total ban on fireworks is a counterproductive measure. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Hand injuries from snow blowers: a report of an epidemic.

PubMed

Tetz, D J; Aghababian, R

1995-01-01

During a record snowfall in Worcester, Massachusetts, 11-13 December 1992, 37 male patients with hand injuries suffered during snow blower operation were seen at three area hospitals. Two previous reports describe 13 patients seen over a 3-year period and 28 patients over a 12-year period. This report describes the largest number of hand injuries from snow blowers that have occurred over a 48-hour period. The snow was unusual because of the high water density in the initial 9 inches (23 cm) that fell at an average temperature of 33 degrees F (0.6 degree C) with the final depth of 30 inches (76 cm), causing the machines to become clogged. Patients admitted to reaching into a running machine in 35/37 (95%) cases, 11/37 (30%) claimed the auger and impeller blades were disengaged, and 2/37 (5%) patients claimed their injuries occurred with the engines turned off. All injuries occurred when the patients placed their hands down the chute, contacting the impeller blades. Injuries involved 32 long, 15 ring, 13 index, and five small fingers and ranged from simple lacerations to partial phalangeal amputations. The majority, 27/37 (73%), were managed in emergency departments without interventions in the operating suites. Infection occurred in one patient who had the lesion repaired in the operating suite. As in previous studies, no differences were found for the variables of snow-blower age, type, or horsepower, or on experience level or age of the operators.(ABSTRACT TRUNCATED AT 250 WORDS)

High-pressure Injection Injuries of the Hand.

PubMed

Cannon, Tyler A

2016-07-01

High-pressure injection hand injuries are often overlooked, with severe complications owing to the acute inflammatory response. Prognosis for depends on the type of material injected, location of injection, involved pressure, and timing to surgical decompression and debridement. Acute management involves broad-spectrum antibiotics, tetanus prophylaxis, emergent decompression within 6 hours, and complete removal of the injected material. Most patients have residual sequelae of stiffness, pain, sensation loss, and difficulties in returning to work. The hand surgeon's role is prompt surgical intervention, early postoperative motion, and education of patient and staff regarding short- and long-term expectations. Copyright © 2016 Elsevier Inc.

Close range gun shot injuries of the hand with the "mole gun".

PubMed

Keskin, Mustafa; Beydes, Tolga; Tosun, Zekeriya; Savaci, Nedim

2009-07-01

A mole gun is a handmade weapon used as a trap to kill moles by farmers. Their action is based on a simple hammer mechanism: when the moles put their head through the metal ring to get hold of the food, they trigger the mechanism. The hammer strikes the primer, which ignites the gunpowder, propelling the pellets from the barrel. The purpose of this study was to report our experiences in a group of patients who accidentally suffered injuries by mole guns to the hand. Since 2000, 20 patients had attended the clinic with mole gun shot injuries to the hand. The mean age of patients was 38 years. Thirteen cases involved skin defects over the dorsum of the hand associated with extensor tendon and bone injuries. The skin defect was covered with posterior interosseous artery (PIA) flap in 12 cases. In one case, the PIA pedicle was found to be injured so radial forearm flap was used. The main intervention time for these cases was 6.2 days. All flaps except two PIA flap survived uneventfully. One flap was completely lost while other survived with distal necrosis. In remaining seven cases the thumb was the main injured part; it had complete disruption of its arterial supply and was managed with amputation with or without matarcarpal removal. These cases were managed immediately. The risk of injury to the PIA by pellets is low in such close range shots to the hand and PIA flap could be used to cover the defects. In such cases, initial debridement should be minimal and the soft tissue, tendon, and bone injury can be managed in the same stage during the first week of injury.

Maggot therapy in treatment of a complex hand injury complicated by mycotic infection.

Complex injuries of the hand remain a therapeutic challenge for surgeons. We present the case of a male who suffered a devastating injury of the hand caused by a conveyor belt. The patient developed a progressive Absidia corymbifera infection of the affected soft tissues. Initial treatments with serial surgical debridement and topical and intravenous itraconazole were unsuccessful in eliminating the infection. We decided to use maggot debridement therapy in a new special design to debride all necrotic, devitalized tissue and preserve only healthy tissue and functioning structures. This maneuverer followed by negative pressure therapy allowed progressive healing. In such complex hand injuries, maggot debridement combined with negative pressure therapy could be considered to achieve effective and considerable results, although future functional morbidity may occur (Fig. 4, Ref. 18).

Several studies have identified the inappropriate use of emergent interfacility transfer as an opportunity to improve health care use. The authors sought to identify common characteristics among children who were transferred from a community hospital to a pediatric tertiary care center for definitive treatment of hand/wrist injuries. All patients undergoing emergent transfer to a pediatric Level I trauma center and academic tertiary referral center for evaluation and management of injuries to the hand/wrist during the 2-year study period were retrospectively identified. Demographic and transfer data were abstracted from the medical record. Referring hospitals were subcategorized by the presence or absence of hand surgical emergency department coverage and the capability to admit/operate on children. Overall, 169 patients were identified who transferred to the authors' institution for hand injuries. There were no differences in the day or time of transfer. Of those transferred, 59 (35%) were admitted for definitive care, of whom 51 (86%) required a surgical intervention within 24 hours. Of the remaining 110 (65%) patients discharged from the emergency department, 27 (25%) underwent elective surgical intervention within 2 weeks. There were a greater number of transfers from institutions without the ability to admit children, regardless of hand surgical emergency department coverage status. Understanding pediatric referral patterns may improve use of emergency department facilities because most patients who were transferred were discharged the same day. Educational outreach and improved interfacility communication may result in enhanced resource use for evaluation and management of pediatric hand injuries. Copyright 2016, SLACK Incorporated.

The purpose of the study was to analyse and compare KT-1000 knee laxity as examined by a left-hand- and a right-hand-dominant physiotherapist in a group of patients with an anterior cruciate ligament (ACL) injury and a group of patients, 2 years after ACL reconstruction. The other aim was to measure and analyse knee laxity in a group of persons without any known knee problems. A cross-sectional examination of two groups of patients pre-operatively and post-operatively after ACL reconstruction and examination of healthy controls on two different occasions was performed. Fifty-three patients who were scheduled for ACL reconstruction and 39 patients who attended a 2-year follow-up examination were included in the study. In the ACL-deficient group, 32 patients had a right-sided ACL injury and 21 patients a left-sided ACL injury. The corresponding figures in the post-operative group were 21 patients with a right-sided ACL injury and 18 patients with a left-sided ACL injury. Twenty-eight healthy persons without any known knee problems served as controls. One left-hand- and one right-hand-dominant experienced physiotherapist performed all the examinations. To be able to evaluate the intra and inter-reliability of the examiners the controls were examined at two occasions. The left-hand-dominant physiotherapist measured significantly higher absolute laxity values in the left knee, both injured and non-injured ones, compared with the right-hand-dominant physiotherapist. This was found irrespectively of whether the patients belonged to the ACL deficient or the post-operative group. In the healthy control group, the right-hand-dominant physiotherapist measured significantly higher knee-laxity values in the right knee compared with the left-hand-dominant physiotherapist. Correspondingly, the left-hand-dominant physiotherapist measured significantly higher knee laxity values in the left knee. We conclude that KT-1000 arthrometer laxity measurements can be affected by the hand

In the past 5 years, 25 mutilated digits were reconstructed with immediate toe-to-hand transfers after acute hand injuries, for 21 patients. The overall results of the immediate toe-to-hand transfers were evaluated and compared with the results of 65 elective procedures performed during the same period by the same surgeon. There were 15 cases of great toe-to-hand transfer for thumb reconstruction, two cases of second toe transfer for index finger reconstruction, and four cases of simultaneous two-toe transfer for reconstruction of multiple-digit amputations. Two cases (two of 25 cases, 8 percent) were successfully salvaged with emergency reexploration. The incidences of emergency reexploration and postoperative infection were not significantly different from those for elective toe-to-hand transfer cases. The duration of industrial insurance coverage was much shorter than for elective cases, averaging 225 days (p < 0.001). Approximately 44 percent of the patients maintained their original jobs after immediate toe-to-hand transfer. The subjective satisfaction self-assessment scores of aesthetic appearance and function for the newly reconstructed thumb averaged 80 and 88 (of a total score of 100), respectively. Although satisfaction was lower than for elective reconstruction (p < 0.001), it was higher than for reconstruction of other digits. The donor-site appearance after great toe harvesting was mostly unsatisfactory. Immediate toe-to-hand transfer provides many advantages over the elective procedure in acute hand injuries, including single-stage reconstruction, shortened convalescence, early return to work, and socioeconomic efficiency. Because there were no significant differences in the success rates, frequencies of complications, or ultimate functional results, immediate toe-to-hand transfer is a safe and reliable procedure that is indicated for specific cases of acute digital amputation.

Injuries sustained to the hand and wrist are common, accounting for 20% of all emergency presentations. The economic burden of these injuries, comprised of direct (medical expenses incurred), indirect (value of lost productivity) and intangible costs, can be extensive and rise sharply with the increase of severity. This paper systematically reviews cost-of-illness studies and health economic evaluations of acute hand and wrist injuries with a particular focus on direct, indirect and intangible costs. It aims to provide economic cost estimates of burden and discuss the cost components used in international literature. A search of cost-of-illness studies and health economic evaluations of acute hand and wrist injuries in various databases was conducted. Data extracted for each included study were: design, population, intervention, and estimates and measurement methodologies of direct, indirect and intangible costs. Reported costs were converted into US-dollars using historical exchange rates and then adjusted into 2015 US-dollars using an inflation calculator RESULTS: The search yielded 764 studies, of which 21 met the inclusion criteria. Twelve studies were cost-of-illness studies, and seven were health economic evaluations. The methodology used to derive direct, indirect and intangible costs differed markedly across all studies. Indirect costs represented a large portion of total cost in both cost-of-illness studies [64.5% (IQR 50.75-88.25)] and health economic evaluations [68% (IQR 49.25-73.5)]. The median total cost per case of all injury types was US$6951 (IQR $3357-$22,274) for cost-of-illness studies and US$8297 (IQR $3858-$33,939) for health economic evaluations. Few studies reported intangible cost data associated with acute hand and wrist injuries. Several studies have attempted to estimate the direct, indirect and intangible costs associated with acute hand and wrist injuries in various countries using heterogeneous methodologies.

Objectives To identify the remediable transient risk factors of occupational hand injuries in Hong Kong in order to guide the development of prevention strategies. Methods The case‐crossover study design was adopted. Study subjects were workers with acute hand injuries presenting to the government Occupational Medicine Unit for compensation claims within 90 days from the date of injury. Detailed information on exposures to specific transient factors during the 60 minutes prior to the occurrence of the injury, during the same time interval on the day prior to the injury, as well as the usual exposure during the past work‐month was obtained through telephone interviews. Both matched‐pair interval approach and usual frequency approach were adopted to assess the associations between transient exposures in the workplace and the short‐term risk of sustaining a hand injury. Results A total of 196 injured workers were interviewed. The results of the matched‐pair interval analysis matched well with the results obtained using the usual frequency analysis. Seven significant transient risk factors were identified: using malfunctioning equipment/materials, using a different work method, performing an unusual work task, working overtime, feeling ill, being distracted and rushing, with odds ratios ranging from 10.5 to 26.0 in the matched‐pair interval analysis and relative risks ranging between 8.0 and 28.3 with the usual frequency analysis. Wearing gloves was found to have an insignificant protective effect on the occurrence of hand injury in both analyses. Conclusions Using the case‐crossover study design for acute occupational hand injuries, seven transient risk factors that were mostly modifiable were identified. It is suggested that workers and their employers should increase their awareness of these risk factors, and efforts should be made to avoid exposures to these factors by means of engineering and administrative controls supplemented by safety

Hand safety for specialty crop production workers: a pilot study investigating frequencies of minor open-wound hand injuries and presence of pathogenic bacteria.

2013-10-01

The purpose of this study was to quantify the presence of minor open-wound hand injuries in addition to Salmonella, Staphylococcus aureus, coliforms, and Escherichia coli on the hands of farm workers who hand-harvest fruit crops in Utah. Data collection was conducted on four farms without USDA Good Agricultural Practices (GAP) certification and on two farms with GAP certification. This study identified essential safety issues that need to be addressed for improving the effectiveness of safety training for migrant farm workers. Farms that have a food safety audit program in place are less likely to have farm workers exposed to pathogenic bacteria and open-wound injuries to their hands. High frequency of S. aureus may indicate a potentially higher risk for wound infection within this worker population. This could lead to infections that are resistant to the antibiotics commonly used to treat ordinary staph infections, resulting in greater work loss time and medical expenses for these workers. Higher frequencies of bacterial presence on workers' hands on non-certified farms indicate a need to identify essential practices to improve worker hygiene habits and on-farm management practices to promote healthy hygiene. Open-wound injuries to migrant farm workers during hand-harvesting could create additional health problems with the possibility of infection and the spread of diseases. Continued research is needed to understand workers' acceptance of these injuries and barriers to personal protection.

Systematic review. Traumatic hand injuries are frequent cause of work related injuries and can result in prolonged durations of time loss from work. To systematically review available evidence to determine which prognostic factors predict return-to-work (RTW) following work-related traumatic hand injuries. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO from 1980 to September 2013 and reference lists of articles. Studies investigating any prognostic factors of RTW after traumatic hand injury were included. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Identified factors were grouped into conceptual prognostic factor categories. We assessed 8 studies, which addressed 11 potential prognostic factors (i.e., sociodemographic factors, occupation, work compensation status, treatment related factors, impairment severity, location of injury, etc.). The quality of the studies was low to moderate. Across all included studies, RTW (original or modified work) occurred in over 60% of individuals by 6 months. There was consistent low-moderate quality evidence that individuals with more severe impairments and lower pre-injury income were less likely to RTW, and low-moderate quality evidence that age, gender and level of education had no impact on RTW. Evidence on other commonly cited prognostic factors were limited in the literature. Impairment severity and lower pre-injury income showed a consistent association with RTW following occupational hand injury, while other factors demonstrated no or variable effects across studies. Additional high-quality studies are warranted toward improving our understanding of the complex factors that mediate RTW following a traumatic work-related hand injury. 2a.

Analysis of Potential Glove-Induced Hand Injury Metrics During Typical Neutral Buoyancy Training Operations

NASA Technical Reports Server (NTRS)

McFarland, Shane

2016-01-01

Injuries to the hands are common among astronauts who train for extravehicular activity. When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. A brief review of NASA's Lifetime Surveillance of Astronaut Health's injury database reveals that 76 percent of astronaut hand and arm injuries from training between 1993 and 2010 occurred either to the fingernail, finger crotch, metacarpophalangeal joint, or fingertip. The purpose of this study was to assess the potential of using small sensors to measure forces acting on the fingers and hand within pressurized gloves and other variables such as skin temperature, humidity, and fingernail strain of a NASA crewmember during typical NBL (Neutral Buoyancy Laboratory) training activity. During the 5-hour exercise, the crewmember seemed to exhibit very large forces on some fingers, resulting in higher strain than seen in previous glove-box testing. In addition, vital information was collected on the glove cavity environment with respect to temperature and humidity. All of this information gathered during testing will be carried forward into future testing, potentially in glove-box- or 1G- (1 gravitational force) or NBL-suited environments, to better characterize and understand the possible causes of hand injury amongst NASA crew.

In order to analyze the frequency, injury rate and cause of on site accidents to the hands of workers on the east coast of lake of Maracaibo in Zulia State, data was obtained from the accident reports registered with the Venezuelan Institute of Social Security. An occupational hand injury was defined as a traumatic injury to the hands, fingers or wrists that occurred while the employee was at work; that resulted from a single exposure to a hazardous agent. The following variables were analyzed: age, severity, economic activity, material agent, mechanic cause, type of injury, type of accident and unsafe action. The frequency rate was used to analyze the annual accident rate. During the period under study 2.456 injuries to the hand were registered, representing 36% of the total injuries reported; 95% were light injuries, 5% incapacitating and two cases resulted in the death of the worker. 72% of the injuries were located in the fingers, 22% in the hands and 6% in the wrists. The greatest frequency of injuries were found in the economic activity in mines and quarries with a rate of 123.1 per thousand. The age group most affected was of 20-29 years (42%), Wounds or contusions and crushings were the injuries most commonly reported, in 39% and 36% of the cases respectively. The main type of injuries were caused by run over, running into or blow from objects. The principal agents causing injuries were materials, substances and radiations in 45% of the cases. It is concluded that the hand injury rate is very high in the exploitation of mines and quarries and represents the main cause of worker's disability.

Background: The purpose of this investigation was to explore prospectively the nature and duration of hand and wrist injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2012. Methods: Longitudinal prospective injury surveillance of the GB boxing squad was performed from 2005 to 2012. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 hours. Results: Finger carpometacarpal instability and finger metacarpophalangeal joint extensor hood and capsule sprain also known as "boxer's knuckle" injuries were significantly more common than other injury diagnoses. The number of injuries during training or competition was similar, which is remarkable given the far greater number of training hours than competition hours performed. Injury rate for hand and wrist injuries in competition was 347 injuries per 1000 hours, while the estimated injury rate in training was <0.5 injuries per 1000 hours. Conclusion: Carpometacarpal instability and boxer's knuckle were more common than any other kind of hand and wrist injury in this cohort of elite amateur boxers. The rate of hand and wrist injuries was higher in competition than in training. Our study highlights the importance of hand and wrist injury prevention in the competition environment.

Loss of hand function is one of the most devastating consequences of spinal cord injury. Intensive hand training provided on an instrumented exercise workstation in conjunction with functional electrical stimulation may enhance neural recovery and hand function. The aim of this trial is to compare usual care with an 8-week program of intensive hand training and functional electrical stimulation. A multicentre randomised controlled trial will be undertaken. Seventy-eight participants with recent tetraplegia (C2 to T1 motor complete or incomplete) undergoing inpatient rehabilitation will be recruited from seven spinal cord injury units in Australia and New Zealand and will be randomised to a control or experimental group. Control participants will receive usual care. Experimental participants will receive usual care and an 8-week program of intensive unilateral hand training using an instrumented exercise workstation and functional electrical stimulation. Participants will drive the functional electrical stimulation of their target hands via a behind-the-ear bluetooth device, which is sensitive to tooth clicks. The bluetooth device will enable the use of various manipulanda to practice functional activities embedded within computer-based games and activities. Training will be provided for one hour, 5 days per week, during the 8-week intervention period. The primary outcome is the Action Research Arm Test. Secondary outcomes include measurements of strength, sensation, function, quality of life and cost effectiveness. All outcomes will be taken at baseline, 8 weeks, 6 months and 12 months by assessors blinded to group allocation. Recruitment commenced in December 2009. The results of this trial will determine the effectiveness of an 8-week program of intensive hand training with functional electrical stimulation.

Measurement properties of the Patient-Rated Wrist and Hand Evaluation: Rasch analysis of responses from a traumatic hand injury population.

PubMed

Packham, Tara; MacDermid, Joy C

2013-01-01

The Patient-Rated Wrist and Hand Evaluation (PRWHE) is a self-reported assessment of pain and disability to evaluate outcome after hand injuries. Rasch analysis is an alternative strategy for examining the psychometric properties of a measurement scale based in item response theory, rather than classical test theory. This study used Rasch analysis to examine the content, scoring and measurement properties of the PRWHE. PRWHE scores (n = 264) from persons with a traumatic injury or reconstructive surgery to one hand were collected from an outpatient hand rehabilitation facility. Rasch analysis was conducted to assess how the PRWHE fit the Rasch model, confirms the scaling structure of the pain and disability subscales, and identifies any areas of bias from differential item functioning. Rasch analysis of the PRWHE supports internal consistency of the scale (α = 0.96) and reliability (as measured by the person separation index) of 0.95. While gender, age, diagnosis, and duration since injury all systematically influenced how people scored the PRWHE, hand dominance and affected side did not. Rasch analysis supported a 3 subscale structure (pain, specific activities and usual activities) rather than the current divisions of pain and disability. Initial examination of the PRWHE indicates the psychometric properties of consistency, reliability and responsiveness previously tested by classical methods are further supported by Rasch analysis. It also suggests the scale structure may be best considered as 3 subscales rather than simply pain and disability. Copyright © 2013 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

At the age of 18 years, jazz guitarist Django Reinhardt (1910-1953) sustained significant burns to his left-hand ring and little fingers; yet, subsequently, he relearned to play and achieved international fame, despite his injuries. Archive film footage and novel motion analysis software were used to compare movements of Django's fretting hand with that of six other guitarists of the same genre. Django employed greater abduction of index and middle fingers (-9.11 ± 6.52° vs -5.78 ± 2.41°; p < 0.001) and more parallel alignment of fingers to the guitar neck (157.7 ± 3.37° vs 150.59 ± 2.67°; p < 0.001) compared to controls. In response to debilitating hand injury, Django developed quantifiable compensatory adaptation of function of his remaining functional fingers by developing an original playing technique. Hand function following injury may be optimized by maximizing latent degrees of freedom in remaining digits, rather than through extensive surgical reconstruction or complex prostheses. Further study of adaptation strategies may inform prosthesis design. © The International Society for Prosthetics and Orthotics 2014.

Work-related hand injuries in Ontario: an historical perspective.

PubMed

Schofield, Michel M E

2005-10-01

Worker's compensation legislation was enacted in Ontario almost 90 years ago. Workers injured on the job gave up their right to sue employers and received no-fault compensation from an independent, employer-funded body called the Workmen's Compensation Board. Three academic health sciences centers in Ontario that are recognized for their commitment to patient care, research, and education compose part of the Specialty Program network with the Ontario Workplace Safety and Insurance Board (WSIB). Statistical data from the WSIB database for workers with hand injuries from 1996 to 2003 show an increase in fractures from fall injuries in the group of women older than 60 that may be related to osteoporosis, a common condition in this group.

Work-related injuries involving a hand or fingers among union carpenters in Washington State, 1989 to 2008.

Lipscomb, Hester J; Schoenfisch, Ashley; Cameron, Wilfrid

2013-07-01

We evaluated work-related injuries involving a hand or fingers and associated costs among a cohort of 24,830 carpenters between 1989 and 2008. Injury rates and rate ratios were calculated by using Poisson regression to explore higher risk on the basis of age, sex, time in the union, predominant work, and calendar time. Negative binomial regression was used to model dollars paid per claim after adjustment for inflation and discounting. Hand injuries accounted for 21.1% of reported injuries and 9.5% of paid lost time injuries. Older carpenters had proportionately more amputations, fractures, and multiple injuries, but their rates of these more severe injuries were not higher. Costs exceeded $21 million, a cost burden of $0.11 per hour worked. Older carpenters' higher proportion of serious injuries in the absence of higher rates likely reflects age-related reporting differences.

Occupational hand injuries: a current review of the prevalence and proposed prevention strategies for physical therapists and similar healthcare professionals.

Hand injury is the second most common work-related musculoskeletal injury among physical therapists (PTs) and other manual therapy professionals such as osteopaths, physiotherapists, chiropractors, acupuncturists and massage therapists. However, the nature and extent of this problem have not been fully explored yet. Therefore, the objective of this study was to review the existing literature published on the prevalence, risk factors, consequences, and prevention of hand injuries among PTs and similar healthcare professionals. The lifetime prevalence of hand injuries was about 15%-46%, and the annual prevalence was reported as 5%-30%. Thumb injuries were found to be the most prevalent of all injuries, accounting more than 50% of all hand-related problems. The most significant risk factors for job-related hand injuries were performing manual therapy techniques, repetitive workloads, treating many patients per day, continued work while injured or hurt, weakness of the thumb muscles, thumb hypermobility, and instability at the thumb joints. PTs reported modifying treatment technique, taking time off on sick leave, seeking intervention, shifting the specialty area, and decreasing patient contact hours as the major consequences of these injuries. The authors recommend that PTs should develop specific preventive strategies and put more emphasis on the use of aids and equipment to reduce the risk of an unnecessary injury.

[Prevention of Occupational Injuries Related to Hands: Calculation of Subsequent Injury Costs for the Austrian Social Occupational Insurance Institution (AUVA)].

Rauner, M S; Mayer, B; Schaffhauser-Linzatti, M M

2015-08-01

Occupational injuries cause short-term, direct costs as well as long-term follow-up costs over the lifetime of the casualties. Due to shrinking budgets accident insurance companies focus on cost reduction programmes and prevention measures. For this reason, a decision support system for consequential cost calculation of occupational injuries was developed for the main Austrian social occupational insurance institution (AUVA) during three projects. This so-called cost calculation tool combines the traditional instruments of accounting with quantitative methods such as micro-simulation. The cost data are derived from AUVA-internal as well as external economic data sources. Based on direct and indirect costs, the subsequent occupational accident costs from the time of an accident and, if applicable, beyond the death of the individual casualty are predicted for the AUVA, the companies in which the casualties are working, and the other economic sectors. By using this cost calculation tool, the AUVA classifies risk groups and derives related prevention campaigns. In the past, the AUVA concentrated on falling, accidents at construction sites and in agriculture/forestry, as well as commuting accidents. Currently, among others, a focus on hand injuries is given and first prevention programmes have been initiated. Hand injuries represent about 38% of all casualties with average costs of about 7,851 Euro/case. Main causes of these accidents are cutting injuries in production, agriculture, and forestry. Beside a low, but costly, number of amputations with average costs of more than 100,000 Euro/case, bone fractures and strains burden the AUVA-budget with about 17,500 and 10,500 € per case, respectively. Decision support systems such as this cost calculation tool represent necessary instruments to identify risk groups and their injured body parts, causes of accidents, and economic activities, which highly burden the budget of an injury company, and help derive

Prospective cohort study. Identification of risk factors for CRPS development in patients with surgically treated traumatic injuries attending hand therapy allows to watch at-risk patients more closely for early diagnosis and to take precautionary measures as required. The aim of this study was to evaluate the risk factors for the development of complex regional pain syndrome (CRPS) after surgical treatment of traumatic hand injuries. In this prospective cohort, 291 patients with traumatic hand injuries were evaluated 3 days after surgery and monitored for 3 months for the development of CRPS. The factors assessed for the development of CRPS were age, sex, manual work, postoperative pain within 3 days measured on a Pain Numerical Rating Scale (0-10), and injury type (crush injury, blunt trauma, and cut laceration injury). CRPS was diagnosed in 68 patients (26.2 %) with a duration of 40.10 ± 17.01 days between the surgery and CRPS diagnosis. The mean postoperative pain score was greater in patients with CRPS than in those without CRPS (P < .001). Patients with pain scores ≥ 5 had a high risk of developing CRPS compared with patients with pain scores <5 (odds ratio: 3.61, confidence interval = 1.94-6.70). Patients with crush injuries were more likely to develop CRPS (odds ratio: 4.74, confidence interval = 2.29-9.80). The patients with a pain score of ≥5 in the first 3 days after surgery and the patients with crush injury were at high risk for CRPS development after surgical treatment of traumatic hand injuries.

The aim of this research study was to gain an understanding of how rural and remote residents in North Queensland, Australia, engaged in work, activities of daily living tasks and social activities following a traumatic hand injury. Findings from a previous retrospective survey with these participants revealed that patients experienced difficulties such as pain for many years after their injury; however, because of the survey methodology, the voices of participants were not heard. This study contributes to a larger project that seeks to propose a model of service delivery to rural and remote residents who have sustained a traumatic injury. Utilising an interpretive phenomenological research design, data were gathered through in-depth, semistructured interviews. Fifteen participants were recruited into this study and questions were designed to explore the experience of having a traumatic hand injury in rural and remote areas of North Queensland. The thematic analysis indicated five major themes: injury and impairment, pain, occupation and activity, and resilience. Participants reported that having a hand injury often caused further injury due to the impairment. The pain experienced could be 'all consuming' yet participants reported 'pushing through' this pain to complete daily tasks. Participants reported that they would 'go mad' if they did not work and highlighted the importance of activity in their recovery. Participants felt grateful at having their hand and thought towards the future. Being self-reliant was important but they were willing to accept support from others when needed. Incorporating activity and occupation in rehabilitation programs as opposed to focusing on strict protocols is an important consideration in the recovery process of rural and remote residents. In particular, engaging in activity and occupation was an important part of managing the pain associated with the hand trauma. This research also found that participants demonstrated resilient

Forty-Year Follow-up of Full-Thickness Skin Graft After Thermal Burn Injury to the Volar Hand.

PubMed

Weeks, Dexter; Kasdan, Morton L; Wilhelmi, Bradon J

2016-01-01

The hands are commonly affected in severe thermal burn injuries. Resulting contractures lead to significant loss of function. Burn contracture release and skin grafting are necessary to restore hand function. We report a case in which surgical reconstruction of a volar hand burn was performed with full-thickness skin grafting. The patient had a 40-year follow-up to assess the function and cosmesis of the repaired hand. We report a case in which a 15-month-old boy presented after receiving third-degree burns to the left volar hand, including the flexural aspects of the index, long, and ring fingers by placing it on a hot kitchen stove burner. The patient subsequently underwent scar contracture release and full-thickness skin grafting. Eleven years after reconstruction, further contractures developed associated with the patient's growth, which were reconstructed with repeat full-thickness skin graft from the inguinal region. No recurrence was witnessed afterward and 40 years after initial injury, the patient maintains full activities of daily living and use of his hand in his occupation. There is debate regarding the superiority of split-thickness versus full-thickness grafts during reconstruction. Our case strengthens the argument for durability of a full-thickness skin graft following thermal burn injury.

To study costs and outcome for serious hand and arm injuries during the first year after the trauma. In patients with a Hand Injury Severity Score (HISS) > 50, DASH and EQ-5D scores as well as factors related to costs within the health care sector, costs due to lost production and total costs were evaluated. Cox-regression analysis stratifying for mechanism of injury was used to analyse return to work. The majority of the 45 included patients (median 42 years 16-64) were men with severe (n = 9) or major (n = 36) injuries with different type of injuries (amputations n = 13; complex injuries n = 18; major nerve injuries/full house n = 13; burn injury n = 1). DASH and EQ-5D decreased and increased, respectively, significantly over time during one year. Total costs (+34%) and costs of lost production were highest for persons injured at work. Factors associated with higher health care costs were age >50 years (+52%), injury at work (+40%) and partial labour market activity (+66%). Costs of lost production had a significant role in total costs of injury. Patients with major injuries had longer duration of sick leave. Patients with severe injuries were more likely to return to work [(RR 3.76 (95% CI 1.38-10.22) from Cox regression, controlling for age, gender and presence of nerve injury]. Despite the fact that work environments have constantly improved over the last decades, we found that hand injuries at work were most costly both in terms of health care and costs of lost production, although the severity, i.e. HISS, did not differ from injuries occurring at home or during leisure.

Background Acute traumatic tendon injuries of the hand and wrist are commonly encountered in the emergency department. Despite the frequency, few studies have examined the true incidence of acute traumatic tendon injuries in the hand and wrist or compared the incidences of both extensor and flexor tendon injuries. Methods We performed a retrospective population-based cohort study of all acute traumatic tendon injuries of the hand and wrist in a mixed urban and rural Midwest county in the United States between 2001-2010. A regional epidemiologic database and medical codes were used to identify index cases. Epidemiologic information including occupation, year of injury, mechanism of injury and the injured tendon and zone were recorded. Results During the 10-year study period there was an incidence rate of 33.2 injuries per 100,000 person-years. There was a decreasing rate of injury during the study period. Highest incidence of injury occurred at 20-29 years of age. There was significant association between injury rate and age, and males had a higher incidence than females. The majority of cases involved a single tendon, with extensor tendon injuries occurring more frequently than flexor tendons. Typically, extensor tendon injuries involved zone three of the index finger, while flexor tendons involved zone two of the index finger. Work-related injuries accounted for 24.9% of acute traumatic tendon injuries. The occupations of work-related injuries were assigned to major groups defined by the 2010 Standard Occupational Classification structure. After assigning these patients' occupations to respective major groups, the most common groups work-related injuries occurred in construction and extraction occupations (44.2%), food preparation and serving related occupations (14.4%), and transportation and material moving occupations (12.5%). Conclusions Epidemiology data enhances our knowledge of injury patterns and may play a role in the prevention and treatment of future

Feasibility Assessment of an EVA Glove Sensing Platform to Evaluate Potential Hand Injury Risk Factors

Injuries to the hands are common among astronauts who train for extravehicular activity (EVA). When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. A brief review of the Lifetime Surveillance of Astronaut Health's injury database reveals that 58% of total astronaut hand and arm injuries from NBL training between 1993 and 2010 occurred either to the fingernail, MCP, or fingertip. The purpose of this study was to assess the potential of using small sensors to measure force acting on the fingers and hand within pressurized gloves and other variables such as blood perfusion, skin temperature, humidity, fingernail strain, skin moisture, among others. Tasks were performed gloved and ungloved in a pressurizable glove box. The test demonstrated that fingernails saw greater transverse strain levels for tension or compression than for longitudinal strain, even during axial fingertip loading. Blood perfusion peaked and dropped as the finger deformed during finger presses, indicating an initial dispersion and decrease of blood perfusion levels. Force sensitive resistors to force plate comparisons showed similar force curve patterns as fingers were depressed, indicating suitable functionality for future testing. Strategies for proper placement and protection of these sensors for ideal data collection and longevity through the test session were developed and will be implemented going forward for future testing.

Severe Crush Injury to the Forearm and Hand: The Role of Microsurgery.

The main goals of treating severe crush injuries are debriding away devitalized tissue and filling any resultant dead space with vascularized tissue. In the authors' experience, the most ideal methods for soft tissue coverage in treating crush injuries are the iliac flap, the adipofascial lateral arm flap, and the gracilis flap. Accompanying bone defects respond very well to free corticoperiosteal flaps. Digital defects often require the use of complete or subtotal toe transfer to avoid amputation and restore function to the hand. Copyright © 2016 Elsevier Inc. All rights reserved.

Disabling hand injuries in boxing: boxer's knuckle and traumatic carpal boss.

Melone, Charles P; Polatsch, Daniel B; Beldner, Steven

2009-10-01

This article describes the treatment of the two most debilitating hand-related boxing injuries: boxer's knuckle and traumatic carpal boss. Recognition of the normal anatomy as well as the predictable pathology facilitates an accurate diagnosis and precision surgery. For boxer's knuckle, direct repair of the disrupted extensor hood, without the need for tendon augmentation, has been consistently employed; for traumatic carpal boss, arthrodesis of the destabilized carpometacarpal joints has been the preferred method of treatment. Precisely executed operative treatment of both injuries has resulted in a favorable outcome, as in the vast majority of cases the boxers have experienced relief of pain, restoration of function, and an unrestricted return to competition.

Injuries and diseases of the hand naturally have an enormous impact on hand function and on quality of life, both occupational and social. The majority of hand-injury patients are under 30 years of age. Hand surgery, an established specialty in Sweden since 1969, is of great importance in terms of clinical developments, education and research. In the coming decade, scientific and clinical advances are to be expected in several fields such as nerve injuries including brachial plexus lesion, microsurgery, flexor tendon injuries and tendon transfer. Bioimplant research and new advances at the biotechnological interface will yield new options in nerve reconstruction, microchip implants in the nervous system, and the restoration of muscle-tendon function following injury. Artificial limbs with advanced motor and sensory functions will be important future aids in the rehabilitation of amputees. Transplantation of human hands is another promising reconstructive procedure which may open up new perspectives in the coming millennium.

To explore how mothers come to terms with the multiple changes that occur with children who sustain sudden brain injuries. A descriptive study based on symbolic interactionist principles. Mothers' homes or a private interview room in a hospital. Seven mothers recruited through a pediatric rehabilitation center. Each mother described her experiences with her child in one open-ended interview. Mothers' lives changed abruptly and profoundly when a previously healthy child suffered a catastrophic brain injury. Their accounts revealed how they had come to regard themselves and the children as "different people" after the injury. Their reconstructions were the result of continuous self-reflection and interactions with others. Mothers had recast life in general from being predictable and controllable to being precarious and dominated by fate. Believing they had no other choice, they played the hand they had been dealt. Nurses can play an important role in helping mothers of children who have brain injuries by reassuring them that feelings of guilt and helplessness are not uncommon, praising them for learning new caregiving skills, and treating children with brain injuries with respect and dignity.

The hand is very exposed to injuries in the daily man's work. The multiple functions of the hand are based on vitality, sensibility, motor function and stability. In severe hand injuries the functional results of the repair are often very poor. In a complex injury of the hand we are faced with the damage of the soft tissue and bone and the loss of vitality and function of the hand. The cause of hand injuries are mainly a crush trauma or the rotating saw. Basically, we recommend an extended primary repair. After the radical debridement we have to reconstruct the damaged structures. We start doing the osteosynthesis and stabilization of the joints. Thereafter, suturing of extensor and flexor tendons. Then, we do the microsurgical reconstructions of vessels and nerves. In case tendons and bones are exposed we have to cover the defect with a pedicled or a free flap. In a long ischemic time we have to change our concept and do the reconstruction of the vessels first. Our results in vitality and sensibility are listed. In the result of a complex hand injury each single functional restoration is very important. Therefore, it is necessary that severe hand injuries are treated at well established centres for hand surgery.

To gain insight into the management of patients with hand and wrist injuries, a series of clinical and psychological analyses was performed on 9 surgeons, each of whom underwent operative fixation of a hand or wrist fracture. The results of these analyses suggest that the functional outcome after hand surgery was affected by the surgeons' personality, motivation, and ability to accept and adapt to the injury, the nature of the injury, and the importance of the hand to the surgeons' careers. Surgeons are highly motivated and compulsive individuals who consider their career involvement a major source of identity and self-worth. Most returned to their operative duties ahead of the schedule set by their hand surgeons (average, 25 days after surgery), regarded their injuries as a positive challenge, and changed their lifestyles after injury to protect their hands.

2016-01-01

In a previous study consensus was sought from Malaysian occupational therapists of occupation-based intervention (OBI) that was perceived as a means and an end. Occupation as a means refers to occupational and purposeful tasks as a therapeutic agent while occupation as an end refers to occupation as an outcome of intervention. The purpose of this follow-up study was to describe the occupational therapists' experiences of providing OBI in hand injury rehabilitation in Malaysia. Sixteen occupational therapists with more than five years of experience in hand rehabilitation were individually interviewed on their experiences of using OBI in practice. Data were thematically analysed using interpretative phenomenological analysis. Definition of "Occupation as a means", and "Occupation as an end" was broadened after data analysis of interviews to include two new themes: "Rewarding yet challenging" and "Making OBI a reality". Occupational therapists had positive experiences with OBI and perceived that occupation as a means and an end can be merged into a single therapy session when the occupational therapists use an occupation that is therapeutic. Although occupation as a means and as an end have different purposes, when the ultimate goal is to enhance the clients' maximum level of functioning both can be used for successful rehabilitation of hand injuries.

The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Further clinical and biomechanical investigations would be advisable to clarify this complex issue.

Modulation of hand aperture during reaching in persons with incomplete cervical spinal cord injury.

The intact neuromotor system prepares for object grasp by first opening the hand to an aperture that is scaled according to object size and then closing the hand around the object. After cervical spinal cord injury (SCI), hand function is significantly impaired, but the degree to which object-specific hand aperture scaling is affected remains unknown. Here, we hypothesized that persons with incomplete cervical SCI have a reduced maximum hand opening capacity but exhibit novel neuromuscular coordination strategies that permit object-specific hand aperture scaling during reaching. To test this hypothesis, we measured hand kinematics and surface electromyography from seven muscles of the hand and wrist during attempts at maximum hand opening as well as reaching for four balls of different diameters. Our results showed that persons with SCI exhibited significantly reduced maximum hand aperture compared to able-bodied (AB) controls. However, persons with SCI preserved the ability to scale peak hand aperture with ball size during reaching. Persons with SCI also used distinct muscle coordination patterns that included increased co-activity of flexors and extensors at the wrist and hand compared to AB controls. These results suggest that motor planning for aperture modulation is preserved even though execution is limited by constraints on hand opening capacity and altered muscle co-activity. Thus, persons with incomplete cervical SCI may benefit from rehabilitation aimed at increasing hand opening capacity and reducing flexor-extensor co-activity at the wrist and hand.

Objective: To observe the effects of functional training combined with self-made hand flexing training band in treatment of scar contracture after burn injury of dorsal hand. Methods: Forty-six patients with scar contracture after deep partial-thickness or full-thickness burn injury of dorsal hand hospitalized in our department from March 2013 to February 2015 were divided into routine training group (RT, n =18) and comprehensive training group (CT, n =28) according to their willingness. Two weeks after the wounds were healed, patients in group RT were treated with functional training of hands and self-made pressure gloves, while patients in group CT were treated with self-made hand flexing training band (consisting of nylon strap, flexing band, and velcro) on the basis of those in group RT. All patients were treated for 3 months. Before and after treatment, scar condition of affected hands was assessed with Vancouver Scar Scale (VSS). The range of motion of joints of affected hands was measured by Total Active Movement (TAM) Scale. The function of affected hands was evaluated by Carroll Upper Extremity Function Test. Data were processed with t test, chi-square test, and Mann-Whitney U test. Results: (1) The score of VSS in patients of group RT was (10.0±1.9) points before treatment and (4.4±1.4) points after treatment, with the improved score of (5.6±1.0) points. The score of VSS in patients of group CT was (10.5±1.8) points before treatment and (4.6±1.4) points after treatment, with the improved score of (5.9±1.2) points. There was no statistically significant difference in the improved score of patients between the two groups ( t =0.834, P >0.05). The score of VSS in patients of groups RT and CT after treatment was significantly lower than that before treatment (with t values respectively 14.014 and 10.003, P values below 0.01). (2) Before treatment, the ratios of excellent and good results according to TAM were 2/9 in patients of group RT and 3/14 in

Acute and chronic disease processes that lead to cerebral injury can often be clinically challenging diagnostically, prognostically, and therapeutically. Neurodegenerative processes are one such elusive diagnostic group, given their often diffuse and indolent nature, creating difficulties in pinpointing specific structural abnormalities that relate to functional limitations. A number of studies in recent years have focused on eye–hand coordination (EHC) in the setting of acquired brain injury (ABI), highlighting the important set of interconnected functions of the eye and hand and their relevance in neurological conditions. These experiments, which have concentrated on focal lesion-based models, have significantly improved our understanding of neurophysiology and underscored the sensitivity of biomarkers in acute and chronic neurological disease processes, especially when such biomarkers are combined synergistically. To better understand EHC and its connection with ABI, there is a need to clarify its definition and to delineate its neuroanatomical and computational underpinnings. Successful EHC relies on the complex feedback- and prediction-mediated relationship between the visual, ocular motor, and manual motor systems and takes advantage of finely orchestrated synergies between these systems in both the spatial and temporal domains. Interactions of this type are representative of functional sensorimotor control, and their disruption constitutes one of the most frequent deficits secondary to brain injury. The present review describes the visually mediated planning and control of eye movements, hand movements, and their coordination, with a particular focus on deficits that occur following neurovascular, neurotraumatic, and neurodegenerative conditions. Following this review, we also discuss potential future research directions, highlighting objective EHC as a sensitive biomarker complement within acute and chronic neurological disease processes.

Management of extravasation injuries over the dorsum of hand after administration of chemotherapeutic agents. To study the results of hypogastric flap reconstruction in chemotherapy extravasation wounds over dorsum of hand. Retrospective study. At our center over 3-years period, 32 patients were treated for chemotherapy extravasation wounds. Out of these 32 patients, seven had wound over dorsum of hand. There were five males and two females, and their mean age was 45 years (range, 19 - 64 years). These patients with wound over the dorsum of hand were treated with multiple debridements and hypogastric flap reconstruction. The mean interval between extravasation wound and surgical treatment was 6.28 days (range, 4 - 10). The mean size of extravasation wound defect was 14 × 8 (range, 12 × 7 to 18 × 8). Non-dominant hand was involved in six patients and dominant hand in one patient. In four patients, the hypogastric flap was supplemented with skin graft. The hypogastric flap settled well in all patients and enabled a good wound cover. Complete division of the flap and final insetting was done under local anesthesia after 3 weeks; this was followed by limb mobilization exercises. Contour difference over the dorsum of hand was present in all the cases. The range of movement of the hand was functionally restricted in one patient. No patient in current series developed wound infection. Hypogastric flap is a reliable flap to cover wound over dorsum of hand after extravasation of chemotherapeutic agents.

The aim of the study was to demonstrate the feasibility, tolerability, and effectiveness of robotic-assisted arm training in incomplete chronic tetraplegia. Pretest/posttest/follow-up was conducted. Ten individuals with chronic cervical spinal cord injury were enrolled. Participants performed single degree-of-freedom exercise of upper limbs at an intensity of 3-hr per session for 3 times a week for 4 wks with MAHI Exo-II. Arm and hand function tests (Jebsen-Taylor Hand Function Test, Action Research Arm Test), strength of upper limb (upper limb motor score, grip, and pinch strength), and independence in daily living activities (Spinal Cord Independence Measure II) were performed at baseline, end of training, and 6 mos later. After 12 sessions of training, improvements in arm and hand functions were observed. Jebsen-Taylor Hand Function Test (0.14[0.04]-0.21[0.07] items/sec, P = 0.04), Action Research Arm Test (30.7[3.8]-34.3[4], P = 0.02), American Spinal Injury Association upper limb motor score (31.5[2.3]-34[2.3], P = 0.04) grip (9.7[3.8]-12[4.3] lb, P = 0.02), and pinch strength (4.5[1.1]-5.7[1.2] lb, P = 0.01) resulted in significant increases. Some gains were maintained at 6 mos. No change in Spinal Cord Independence Measure II scores and no adverse events were observed. Results from this pilot study suggest that repetitive training of arm movements with MAHI Exo-II exoskeleton is safe and has potential to be an adjunct treatment modality in rehabilitation of persons with spinal cord injury with mild to moderate impaired arm functions.

Cost per case or total cost? The potential of prevention of hand injuries in young children – Retrospective and prospective studies

Background Health-care costs for hand and forearm injuries in young children are poorly documented. We examined costs in 533 children injured years 1996–2003. Methods Health-care costs and costs for lost productivity were retrospectively calculated in children from three catchment areas in Sweden. Seven case categories corresponding to alternative prevention strategies were constructed. Results Over time, diminishing number of ward days reduced the health-care cost per case. Among children, the cost of lost productivity due to parental leave was 14 percent of total cost. Fingertip injuries had low median costs but high total costs due to their frequency. Complex injuries by machine or rifle had high costs per case, and despite a low number of cases, total cost was high. Type of injury, surgery and physiotherapy sessions were associated with variations in health-care cost. Low age and ethnic background had a significant effect on number of ward days. Conclusion The costs per hand injury for children were lower compared to adults due to both lower health-care costs and to the fact that parents had comparatively short periods of absence from work. Frequent simple fingertip injuries and rare complex injuries induce high costs for society. Such costs should be related to costs for prevention of these injuries. PMID:18606018

Rehabilitation of flexor and extensor tendon injuries in the hand: current updates.

PubMed

Howell, Julianne W; Peck, Fiona

2013-03-01

In recent years, a significant amount of research in the field of tendon injury in the hand has contributed to advances in both surgical and rehabilitation techniques. The introduction of early motion has improved tendon healing, reduced complications, and enhanced final outcomes. There is overwhelming evidence to show that carefully devised rehabilitation programs are critical to achieving favourable outcomes. Whatever the type, or level, of flexor or extensor injury, the ultimate goal of both the surgeon and therapist is to protect the repair, modify peritendinous adhesions, promote optimal tendon excursion and preserve joint motion. Early tendon motion regimens are initiated at surgery or within 5 days post repair. Intra-operative information from the surgeon to the therapist is vital to the choice of splint protected position to reduce repair rupture/gap forces, and to commencement of active, or splint controlled, motion for tendon excursion. Decisions should align with the phases of healing, the clinician's observations, frequent range of motion measurements and patient input. Clinical concepts pertinent to early motion rehabilitation decisions are presented by zone of injury for both flexor and extensor tendons during the early phases of healing. Copyright © 2013.

The application of a modified neuroprosthetic hand system in a child with a C7 spinal cord injury. Case report.

PubMed

Smith, B T; Mulcahey, M J; Triolo, R J; Betz, R R

1992-08-01

A neuroprosthetic hand system developed at Case Western Reserve University has been modified for use by an 8 year old child with an incomplete C7 spinal cord injury. This system has been adapted to accommodate voluntary thumb and finger extension, and provides stimulated finger flexion and thumb position for lateral and palmar prehension. Three months were required to develop grasp with sufficient strength and coordination for functional use. This period consisted of: implantation and immobilization of percutaneous intramuscular electrodes; stimulated exercise of the muscles of the hand and forearm; programming grasp patterns; and system training. Functional assessments show that the neuroprosthetic hand system allows the subject to perform unilateral and bilateral tasks that were otherwise impossible or were previously performed bimanually. The ability to perform activities of daily living with one hand frees the contralateral upper extremity to be used either for balance which increases the work area, or to stabilize an object allowing manipulation with the instrumented hand. Telephone interviews suggest that the hand system is used on a consistent basis at home and school. This single subject application indicates that a stimulation system designed for adults with C5-6 spinal cord injuries can enhance hand function and facilitate independence in a child with a low level cervical lesion.

Case-control study. Hospital and local community. Patients with PNI (n=28) were recruited along with age-, sex-, and handedness-matched healthy controls (n=28) (N=56). Not applicable. The Semmes-Weinstein monofilament, moving and static 2-point discrimination, roughness differentiation, stereognosis and barognosis subtests of the MTT, and precision pinch performance were used to examine the sensory and sensorimotor status of the hand. The worst results in all sensibility tests were found for the patients with PNI (P<.001) in comparison with the controls. Multiple linear regression analysis showed the MTT was a better indicator for predicting the sensorimotor capacity of hands in the patients with PNI (r(2)=.189, P=.003) than the traditional test (r(2)=.088, P=.051). The results of the receiver operating characteristic curve estimation show that the area under the curve was .968 and .959 for the roughness differentiation and stereognosis subtests, respectively, and .853 for the barognosis subtest, therefore revealing the accuracy of the MTT in assessing sensorimotor status for patients with PNI. This study indicates that the MTT is highly accurate and a significant predictor of sensorimotor performance in hands of patients with PNI. The MTT could therefore help clinicians obtain a better understanding of the sensorimotor and functional status of the hand with nerve injuries.

Hand injuries are common, contributing up to 30% of accident and emergency (A&E) attendances. The aim of this study was to prospectively analyse the pathological demographics of hand injuries in a level 1 trauma centre with a Hand Trauma Unit and direct A&E links, and compare clinical and intra-operative findings. The null hypothesis was that there would be no differences between clinical and intra-operative findings (100% diagnostic concordance). Data were prospectively collected for referrals during 2012. Referral diagnosis, additional pathologies found on clinical assessment and intra-operative findings were documented on a live database accessible from both the Hand Unit and associated operating theatres. Odds ratios were calculated using SAS. Injuries (1526) were identified in 1308 patients included in the study. Diagnostic concordance between Hand Unit clinical examination and intra-operative findings was 92.5% ± 2.85% (mean ± SEM); this was lower for flexor tendon injuries (56.3%) because a greater number of additional pathologies were found intra-operatively (2.25 ± 0.10). This 'trend' was noted across multiple referral pathologies including phalangeal fractures (1.28 ± 0.02; 82.9%), lacerations (1.33 ± 0.04; 79.1%), extensor tendon injuries (1.30 ± 0.05; 87.8%) and dislocations (1.18 ± 0.05; 87.8%). Odds ratio analysis indicated a relationship between primary referral diagnoses that were more or less likely to be associated with additional injuries (p < 0.05); referral diagnoses of flexor tendon injuries and lacerations were most likely to be associated with additional injuries. As hand injuries are a common presentation to A&E departments, greater emphasis should be placed on training clinicians in the management of hand trauma. Our findings, coupled with the presented relevant literature reports, lead us to advocate that A&E departments should move towards a system wherein links to specialist hand trauma services are in place; we

Booby traps and gun-like devices for vole control can lead to complex trauma requiring emergency medical care. We present a case series of patients who suffered severe hand and facial trauma through detonation of booby traps and paraphernalia (n = 9, Ø 60 years of age). All patients were admitted to the emergency department of Hannover Medical School for primary care. Between 2011 and 2015 we treated six patients with hand trauma due to gun-like devices, two patients with hand trauma due to booby traps, and one patient with injury to the face including eyes due to a gas cartridge explosion. All hand trauma patients (n = 8) showed injuries of the soft tissue. Six of these patients also presented fractures or lesions of capsular or tendon structures. Therapies included debridement as well as skin grafts or flaps for tissue defect coverage. We informed the Department for Commercial Safety (Gewerbeaufsicht Hannover) in 2014 because we believe that these traps pose a serious safety hazard.

Case Report: The casting motion to mobilize stiffness technique for rehabilitation after a crush and degloving injury of the hand.

Case report. This case report describes the use of the casting motion to mobilize stiffness (CMMS) technique in the management of a crush and degloving injury of the hand. The patient was unable to attend multiple hand therapy sessions due to geographic constraints. The CMMS technique involved the application of a nonremovable plaster of paris cast that selectively immobilizes proximal joints in an ideal position while constraining distal joints to direct desired motion over a long period. This uses active motion only. Traditional hand therapy techniques or modalities are not used. This treatment approach was beneficial to the patient as a minimum of 2 appointments per month were needed to regain functional hand use. To document the use of the CMMS technique as an effective treatment approach in the management of a crush and degloving injury of the hand. The CMMS technique was applied to the patient's left (nondominant) hand 8 weeks after injury. The technique's aim was to improve the 30° flexion deformity of the left wrist and flexion contractures of the index, middle, and ring fingers with a total active motion of 0°. Orthotic devices and traditional therapy were applied once joint stiffness was resolved, and a normal pattern of motion was reinstated. At 6 months, substantial improvement was noted in wrist as well as metacarpophalangeal and interphalangeal joints. Total active motion exceeded 170° in all fingers excellent functional outcome resulted as measured with the upper limb functional index short form-10. The upper limb functional index increased from 0% to 55% of preinjury status (or capacity) over the 18 months of therapy. Brief immobilization through casting causes certain functional losses, but these are temporary and reversible. Finger stiffness, edema, and tissue fibrosis were successfully managed with the CMMS technique without the need for attendance at multiple hand therapy sessions. Level V.

We gathered seven specialists from various fields who are interested in worker injury prevention programs, based on cases of patients who had suffered refractory injuries requiring hand surgery because of industrial accidents. The patients were asked to write their thoughts and ideas on the theme, "Measures that must be implemented to prevent arm injuries." The content obtained was classified into different categories, using the KJ method, and was scripted to sort out the items. As a result, the following eleven points were identified as measures to prevent serious hand surgery-related injuries: 1. Purchase safe machinery, 2. Create a list of machines that require caution, 3. Enclose a machine's various rotating parts, 4. Carry out periodic maintenance work on the machines, 5. Indicate dangerous areas by putting up signs that attract attention, 6. Illuminate the rotating parts more brightly and avoid placing objects around them, 7. Systematically carry out safety education that creates a strong impact, 8. Encourage workers to look after their own health, 9. Announce policies on health and safety, 10. Re-examine the operational procedures, and 11. Be prepared in case an accident occurs. A perspective based on the results of this research is deemed important in creating a workplace improvement manual in the future.

There is a paucity of clinical data on severe fireworks-related injuries, and the relationship between firework types, injury patterns, and magnitude of impairment is not well understood. Our objective was to describe the relationship between fireworks type, injury patterns, and impairment. Retrospective case series (2005-2015) of patients who sustained consumer fireworks-related injuries requiring hospital admission and/or an operation at a Level 1 Trauma/Burn Center. Fireworks types, injury patterns (body region, injury type), operation, and permanent impairment were examined. Data from 294 patients 1 to 61years of age (mean 24years) were examined. The majority (90%) were male. 119 (40%) patients were admitted who did not undergo surgery, 163 (55%) patients required both admission and surgery, and 12 (5%) patients underwent outpatient surgery. The greatest proportion of injuries was related to shells/mortars (39%). There were proportionally more rocket injuries in children (44%), more homemade firework injuries in teens (34%), and more shell/mortar injuries in adults (86%). Brain, face, and hand injuries were disproportionately represented in the shells/mortars group. Seventy percent of globe-injured patients experienced partial or complete permanent vision loss. Thirty-seven percent of hand-injured patients required at least one partial or whole finger/hand amputation. The greatest proportion of eye and hand injuries resulting in permanent impairment was in the shells/mortars group, followed by homemade fireworks. Two patients died. Severe fireworks-related injuries from homemade fireworks and shells/mortars have specific injury patterns. Shells/mortars disproportionately cause permanent impairment from eye and hand injury.

A significant number of astronauts sustain hand injuries during extravehicular activity training and operations. These hand injuries have been known to cause fingernail delamination (onycholysis) that requires medical intervention. This study investigated correlations between the anthropometrics of the hand and susceptibility to injury. The analysis explored the hypothesis that crewmembers with a high finger-to-hand size ratio are more likely to experience injuries. A database of 232 crewmembers' injury records and anthropometrics was sourced from NASA Johnson Space Center. No significant effect of finger-to-hand size was found on the probability of injury, but circumference and width of the metacarpophalangeal (MCP) joint were found to be significantly associated with injuries by the Kruskal-Wallis test. A multivariate logistic regression showed that hand circumference is the dominant effect on the likelihood of onycholysis. Male crewmembers with a hand circumference > 22.86 cm (9") have a 19.6% probability of finger injury, but those with hand circumferences < or = 22.86 cm (9") only have a 5.6% chance of injury. Findings were similar for female crewmembers. This increased probability may be due to constriction at large MCP joints by the current NASA Phase VI glove. Constriction may lead to occlusion of vascular flow to the fingers that may increase the chances of onycholysis. Injury rates are lower on gloves such as the superseded series 4000 and the Russian Orlan that provide more volume for the MCP joint. This suggests that we can reduce onycholysis by modifying the design of the current gloves at the MCP joint.

The incidence of hand infections caused by penetrating fish fins or bones injuries (FFBI) is likely to increase following worldwide constant growth of fishery production and consumption. Because data on these infections are scarce, the purposes of this study were to describe their clinical characteristics and disease course, and to analyze risk factors for a complicated disease course. We studied retrospectively all cases of hospitalized patients with hand infections following FFBI over the years 1999-2006 in a single medical center. Demographic data, underlying diseases, clinical characteristics and disease course were analyzed for each case. Univariate and multivariate analysis were used for analyzing risk factors for a complicated hospitalization course. There were 122 separate episodes of hand infections following FFBI among 116 patients, with a mean age (+/- SD) of 52 +/- 19.7. The majority of cases were women (51.6%), and they arrived significantly later to the hospital after injury. Predisposing conditions (diabetes mellitus, liver disease, rheumatologic disorder, malignancy or chronic steroid treatment) were present in 25% of cases. Most of the cases presented with cellulitis. Cultures of either blood or wound were obtained in approximately 1/3 of cases, and 40% of them yielded an isolate. Ceftazidime and doxycycline were administered to 68.8% and 96.7% of cases, respectively. Surgical debridement was performed in 34.4% of cases, but there was no case of death or limb amputation. The presence of fever (p = 0.0005) and a predisposing condition (p = 0.035) were independently correlated with a complicated hospitalization course. The overall prognosis in this largest cohort of hand infections following FFBI was favorable, but immune dysfunction carried a complicated course.

Crossed cerebello-cerebral diaschisis (CCCD) conventionally refers to decreased resting cerebral activity caused by injury to the contralateral cerebellum. We investigated whether functional activation of a contralesional cerebral cortical region controlling a specific task is reduced during task performance in a patient with a unilateral cerebellar lesion. We also examined functional compensation by the corresponding ipsilesional cerebral cortex. It was hypothesized that dysfunction of the primary sensorimotor cortex (SM1) contralateral to the cerebellar lesion would be detected together with a compensatory increase in neural activity of the ipsilesional SM1. To test these possibilities, we conducted non-invasive functional neuroimaging techniques for bilateral SM1 during hand grasping, a task known to activate predominantly the SM1 contralateral to the grasping hand. Activity in SM1 during hand grasping was measured electrophysiologically by magnetoencephalography and hemodynamically by near-infrared spectroscopy in an adult with mild right hemiataxia associated with a large injury of the right cerebellum due to resection of a tumor in early childhood. During left hand grasping, increased neural activity was detected predominantly in the right SM1, the typical developmental pattern. In contrast, neural activity increased in the bilateral SM1 with slight right-side dominance during right (ataxic) hand grasping. This study reported a case that implied functional CCCD and compensatory neural activity in the SM1 during performance of a simple hand motor task in an adult with unilateral cerebellar injury and mild hemiataxia 24 years prior to the study without rehabilitative interventions. This suggests that unilateral cerebellar injuries in early childhood may result in persistent functional abnormalities in the cerebrum into adulthood. Therapeutic treatments that target functional CCCD and interhemispheric compensation might be effective for treating ataxia due to

Hand fracture fixation in mutilating injuries is characterized by multiple challenges due to possible skeletal disorganization and concomitant severe injury of soft tissue structures. The effects of skeletal disruption are best analyzed as divided into specific locales in the hand: radial, ulnar, proximal, and distal. Functional consequences of injuries in each of these regions are discussed. Although a variety of implants are now in vogue, K-wire fixation has stood the test of time and is especially useful in multiple fracture situations. Segmental bone loss is quite common in such injuries, which can be safely reconstructed in a staged manner. Copyright © 2016 Elsevier Inc. All rights reserved.

In France at the present time, there is no comprehensive registry of hand injuries. Three types of occurrences; motor vehicle accidents, work accidents, and accidents incident to activities of daily living, are covered by different types of insurance. It is the individual insurance companies, payers of the indemnification, who maintain registries of these accidents. Statistics on work accidents are very detailed and consistent, but they are oriented toward risk management. The aggregate cost of traumatic injuries to the hand is not known. Only large financial institutions are equipped to determine appropriate preventive measures and to establish premium rates based on loss experience. In 2001, hand injuries accounted for 27% of work accidents causing loss of work of at least 1 day. About 29.8% of these work accidents caused permanent partial impairment. About 17.7% of total days lost and 18.2% of the total costs of permanent impairment were due to hand injuries. In the system of compensation for work accidents, there is a major difference in the cost according to the severity of the impairment. If the permanent impairment is equal to or less than 9%, a lump sum payment is made, but if the permanent impairment is over 9%, the worker receives regular payments for the rest of his life. In 2000, the average cost of a work injury with partial permanent impairment of over 9% was [symbol: see text] 85,405, while the average cost of a lump sum settlement was only [symbol: see text] 1479, a ratio of 57 to 1. The compensation costs represent 80% of the cost of work accidents, while the cost of treatment, including all providers and institutions, makes up only 20% of the cost. Compensation for sequelae of accidents in the course of daily life is new for the insurance companies, although these accidents are frequent and often cause significant repercussions in the professional lives of victims because of the loss of hand function.

Burn scar contractures are perhaps the most frequent and most frustrating sequelae of thermal injuries to the hand. Unfortunately, stiffness occurs in the burned hand quickly. A week of neglect in the burned hand can lead to digital malpositioning and distortion that may be difficult to correct. The dorsal contracture is the most common of all the complications of the burned hand. It is the result of damage to the thin dorsal skin and scant subcutaneous tissue, which offers little protection to the deeper structures. Consequently, these injuries are deep resulting in a spectrum of deformities that has remained the bane of reconstructive surgery. Flap coverage will be required in the event of exposure of joints and tendons with absent paratenons. Multiple different flap types are available to treat complex severe postburn hand contractures. In our center, which is the largest regional burn center in northwest Iran, we have considerable experience in the treatment of thermal hand injuries. Between 2005 and 2010, we treated 53 consecutive patients with 65 severe postburn hand deformities. There were 35 men and 18 women with a mean age of 35±3 years. Flame injury was the inciting traumatic event in each patient. The severity of original injury and inadequate early treatment resulted in all of the fingers developing a severe extension contracture with scarred and adherent extensor tendons and subluxed metacarpophalangeal joints. In 36 cases, the injury was in the patients' dominant hand. We first incised the dorsal aspect of the contracted hands where there was maximum tension, then tenolysed the extensor tendons and released the volar capsules, collateral ligaments, and volar plate in all cases. In 30 cases, we also tenolysed the flexor tendons. We reduced the subluxed metacarpophalangeal joints and fixed them with Kirschner wires in 70 to 90 degrees flexion. Then, we planned and performed axial groin flaps to reconstruct the defects in all of them. In all of these

Injury Risk Assessment of Extravehicular Mobility Unit (EMU) Phase VI and Series 4000 Gloves During Extravehicular Activity (EVA) Hand Manipulation Tasks

Functional Extravehicular Mobility Units (EMUs) with high precision gloves are essential for the success of Extravehicular Activity (EVA). Previous research done at NASA has shown that total strength capabilities and performance are reduced when wearing a pressurized EMU. The goal of this project was to characterize the human-space suit glove interaction and assess the risk of injury during common EVA hand manipulation tasks, including pushing, pinching and gripping objects. A custom third generation sensor garment was designed to incorporate a combination of sensors, including force sensitive resistors, strain gauge sensors, and shear force sensors. The combination of sensors was used to measure the forces acting on the finger nails, finger pads, finger tips, as well as the knuckle joints. In addition to measuring the forces, data was collected on the temperature, humidity, skin conductance, and blood perfusion of the hands. Testing compared both the Phase VI and Series 4000 glove against an ungloved condition. The ungloved test was performed wearing the sensor garment only. The project outcomes identified critical landmarks that experienced higher workloads and are more likely to suffer injuries. These critical landmarks varied as a function of space suit glove and task performed. The results showed that less forces were acting on the hands while wearing the Phase VI glove as compared to wearing the Series 4000 glove. Based on our findings, the engineering division can utilize these methods for optimizing the current space suit glove and designing next generation gloves to prevent injuries and optimize hand mobility and comfort.

Electrocution injuries account for a significant amount of burns unit admissions each year, and can be fatal. These injuries are divided into high-voltage (over 1000 volts) and low-voltage (less than 1000 volts) injuries, with lightning strikes (greater than 100 million volts) considered separately. Although the majority of electrocution injuries are of low voltage, most of the published reports concern industrial/high-voltage and lightning injuries. This disparity may trivialize low-voltage injuries in the minds of clinicians. We report a rare case of trineural (median, ulnar, and radial) injury in an upper limb after a low-voltage electrocution, and discuss the pathogenesis, investigation, and treatment of these injuries.

This study compares surgical techniques and surgeon's standing position during laparoscopic cholecystectomy (LC), investigating each with respect to surgeons' learning, performance, and ergonomics. Little homogeneity exists in LC performance and training. Variations in standing position (side-standing technique vs. between-standing technique) and hand technique (one-handed vs. two-handed) exist. Thirty-two LC procedures performed on a virtual reality simulator were video-recorded and analyzed. Each subject performed four different procedures: one-handed/side-standing, one-handed/between-standing, two-handed/side-standing, and two-handed/between-standing. Physical ergonomics were evaluated using Rapid Upper Limb Assessment (RULA). Mental workload assessment was acquired with the National Aeronautics and Space Administration-Task Load Index (NASA-TLX). Virtual reality (VR) simulator-generated performance evaluation and a subjective survey were analyzed. RULA scores were consistently lower (indicating better ergonomics) for the between-standing technique and higher (indicating worse ergonomics) for the side-standing technique, regardless of whether one- or two-handed. Anatomical scores overall showed side-standing to have a detrimental effect on the upper arms and trunk. The NASA-TLX showed significant association between the side-standing position and high physical demand, effort, and frustration (p<0.05). The two-handed technique in the side-standing position required more effort than the one-handed (p<0.05). No difference in operative time or complication rate was demonstrated among the four procedures. The two-handed/between-standing method was chosen as the best procedure to teach and standardize. Laparoscopic cholecystectomy poses a risk of physical injury to the surgeon. As LC is currently commonly performed in the United States, the left side-standing position may lead to increased physical demand and effort, resulting in ergonomically unsound conditions for

Hand screen-printing (HSP) plays a predominant role in textile industries in developing countries. Workers from HSP industry were mostly affected by musculoskeletal injury due to monotonous, and prolonged work nature and poor workplace environment. The present study aims to investigate the prevalence of work-related musculoskeletal disorder (MSD) symptoms and risk factors associated among the HSP industry workers. Cochran's sample size for categorical data was used to select 385 HSP workers of 1000 samples from various provinces of Tamil Nadu, INDIA. Modified Nordic based questionnaire was used to assess the musculoskeletal injuries and risk factors among HSP workers. The statistical analysis revealed that 62.5% workers are prone to MSD symptoms with lower back (75.1%), shoulder (66.2%), knees (58.7%), and ankle/feet (55.6%). Age, experience, marital status, stress in the job were the risk factors which significantly (p < 0.05) associated with the reported MSDs. Further, this study result infers that the subjects with higher age and experience are exposed higher levels of MSD prevalence of 85.5% and 92.0% respectively in past 12 months than other groups. Among the different work categories in HSP task, the workers reported with the maximum discomfort during printing work (63.1%) with Odds ratio as 10.38 and 95% CI is 6.18-17.4. than the material handling and drying task. Study results infer that HSP workers are prone to lower back and shoulder pain followed by knees and ankle feet regions. Socio-demographic factors, awkward posture and repetitive movements contribute to cause MSD among hand screen-printing workers.

A mole gun is a weapon, which is used to trap and kill moles. This report provides an overview of the state of knowledge of mole gun injuries, comparable to blast injuries caused by fireworks, explosive or gunshot. Over a 2-year period, the authors reported their experience with ten hand injuries caused by mole gun. Radial side of the hand was often concerned, particularly the thumb. The authors explain their choices in the management of such lesions. Surgery was performed primarily and a large debridement currently seemed to offer the best outcome for the patient. Blast, crush, burns and lacerations may explain the higher rate of amputation to the digits. A long period of physiotherapy, specifically of the hand, was needed before the patient could return to work. This ballistic hand trauma encountered by surgeons requires knowledge and understanding of these injuries. It should be in accordance with firearms law because of severe injuries encountered and possible lethal wounds. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

OBJECTIVE: To document long-term results associated with an coordinated plan of care for acutely burned hands in children. SUMMARY AND BACKGROUND DATA: Optimal hand function is a crucial component of a high-quality survival after burn injury. This can be achieved only with a coordinated approach to the injuries. Long-term outcomes associated with such a plan of care have not been previously reported. METHODS: Over a 10-year period, 495 children with 698 acutely burned hands were managed at a regional pediatric burn facility; 219 children with 395 injured hands were followed in the authors' outpatient clinic for at least 1 year and an average of >5 years. The authors' approach to the acutely burned hand emphasizes ranging and splinting throughout the hospital stay, prompt sheet autograft wound closure as soon as practical, and the selective use of axial pin fixation and flaps. Long-term follow-up, hand therapy, and reconstructive surgery are emphasized. RESULTS: Normal functional results were seen in 97% of second-degree and 85% of third-degree injuries; in children with burns involving underlying tendon and bone, 70% could perform activities of daily living and 20% had normal function. Reconstructive hand surgery was required in 4.4% of second-degree burns, 32% of third-degree burns, and 65% of those with injuries involving underlying bone and tendon. CONCLUSIONS: When managed in a coordinated long-term program, the large majority of children with serious hand burns can be expected to have excellent functional results. Images Figure 1. Figure 2.

During a 6-month period, the poison center was consulted on three occasions for advice regarding accidental injection of hexafluorethane (Freon) used in the manufacturing process of athletic shoes. A fourth case was later identified after consulting physicians near the manufacturing facility. Little information exists in the medical literature concerning injection of freon or other volatile substances. In each of these cases, workers inadvertently injected concentrated hexafluorethane into a finger while holding the shoe component and attempting to inject hexafluorethane. Each case presented with edema, limitation of motion, and crepitation. Hand roentgenogram revealed subcutaneous gas. Treatment was nonsurgical, consisting of splinting,more » tetanus immunization, and antibiotics. Rapid resolution of symptoms occurred in all four cases.

To investigate the effectiveness of dorsalis pedis flap series-parallel big toe nail composite tissue flap in the repairment of hand skin of degloving injury with tumb defect. Between March 2009 and June 2013, 8 cases of hand degloving injury with thumb defect caused by machine twisting were treated. There were 7 males and 1 female with the mean age of 36 years (range, 26-48 years). Injury located at the left hand in 3 cases and at the right hand in 5 cases. The time from injury to hospitalization was 1.5-4.0 hours (mean, 2.5 hours). The defect area was 8 cm x 6 cm to 15 cm x 1 cm. The thumb defect was rated as degree I in 5 cases and as degree II in 3 cases. The contralateral dorsal skin flap (9 cm x 7 cm to 10 cm x 8 cm) combined with ipsilateral big toe nail composite tissue flap (2.5 cm x 1.8 cm to 3.0 cm x 2.0 cm) was used, including 3 parallel anastomosis flaps and 5 series anastomosis flaps. The donor site of the dorsal flap was repaired with thick skin grafts, the stumps wound was covered with tongue flap at the shank side of big toe. Vascular crisis occurred in 1 big toe nail composite tissue flap, margin necrosis occurred in 2 dorsalis pedis flap; the other flaps survived, and primary healing of wound was obtained. The grafted skin at dorsal donor site all survived, skin of hallux toe stump had no necrosis. Eight cases were followed up 4-20 months (mean, 15.5 months). All flaps had soft texture and satisfactory appearance; the cutaneous sensory recovery time was 4-7 months (mean, 5 months). At 4 months after operation, the two-point discrimination of the thumb pulp was 8-10 mm (mean, 9 mm), and the two-point discrimination of dorsal skin flap was 7-9 mm (mean, 8.5 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the results were excellent in 4 cases, good in 3 cases, and fair in 1 case. The donor foot had normal function. Dorsalis pedis flap series-parallel big toe nail composite tissue flap is an ideal

A comparison of upper limb amputees and patients with upper limb injuries using the Disability of the Arm, Shoulder and Hand (DASH).

PubMed

Davidson, Judith

To use the Disability of the Arm Shoulder and Hand (DASH) scale to measure the disability of patients with upper limb amputation(s) and to compare these to other upper limb injuries. All 274 patients over the age of 18 years presenting to Prince Henry Hospital in Sydney over a 4-year time frame were given the DASH assessment tool and asked to complete it under supervision of the Occupational Therapist. Patients with brachial plexus injuries, Complex Regional Pain Syndrome and bilateral upper limb amputations demonstrated significantly higher levels of disability to patients with unilateral upper limb amputations. Partial hand amputees reported a higher level of disability than major unilateral upper limb amputees. For the 48 patients who completed pre- and post-treatment assessments, there was a significant improvement in their health status. Further research is required to understand the factors that affect a patient's perceptions of their disability. Perhaps the definitive nature of an amputation and the immediate involvement of highly skilled health professionals serve to assist patients to accept their injury and therefore minimizes the level of disability.

Hand score at latest followup or by telephone, and complications were assessed by chart review. All fractures were healed with stable MCP joints. Eight patients reported having no pain or minimal pain of their injuries to the hand. The median finger and thumb MCP arc of motion were 80° (range, 70°-105°) and 30° (range, 0°-60°), respectively. The median Quick Disabilities of the Arm, Shoulder and Hand score was 3 (range, 0-41). One patient underwent a second surgical procedure for bone grafting and soft tissue coverage. Three patients developed pin site irritations and were treated with oral antibiotics. Six patients returned to their original job. The distraction pinning technique provides reliable osseous union and joint stability of comminuted pilon-type fractures of the base of the proximal phalanx or metacarpal head, even with associated open wounds. Future studies will need to evaluate these patients at longer term followup and compare this approach with other available techniques, because arthrosis, stiffness, and progressive loss of function seem likely to occur given the severity of these injuries.

Nerve injuries of the upper extremity and hand

Dahlin, Lars B.; Wiberg, Mikael

2017-01-01

A nerve injury has a profound impact on the patient’s daily life due to the impaired sensory and motor function, impaired dexterity, sensitivity to cold as well as eventual pain problems. To perform an appropriate treatment of nerve injuries, a correct diagnosis must be made, where the injury is properly classified, leading to an optimal surgical approach and technique, where timing of surgery is also important for the outcome. Knowledge about the nerve regeneration process, where delicate processes occur in neurons, non-neuronal cells (i.e. Schwann cells) and other cells in the peripheral as well as the central nervous systems, is crucial for the treating surgeon. The surgical decision to perform nerve repair and/or reconstruction depends on the type of injury, the condition of the wound as well as the vascularity of the wound. To reconnect injured nerve ends, various techniques can be used, which include both epineurial and fascicular nerve repair, and if a nerve defect is caused by the injury, a nerve reconstruction procedure has to be performed, including bridging the defect using nerve-grafts or nerve transfer techniques. The patients must be evaluated properly and regularly after the surgical procedure and appropriate rehabilitation programmes are useful to improve the final outcome.

Nelson, Clayton E; Rayan, Ghazi M; Judd, Dustin I; Ding, Kai; Stoner, Julie A

2017-07-01

Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries. A 24-question online survey was distributed to rock climbers about upper extremity injuries sustained during rock climbing. Statistical analysis was used to study association between participants' demographics and injuries. A total of 397 participants responded to the survey. Mean age was 32.5 years with males comprising 85%. No significant differences in demographics or climbing behaviors were found between males and females. Ninety percent of participants reported sustaining an upper extremity injury. Fingers were the most common injury followed by shoulder/arm and elbow/forearm. Our study found females to be more likely to report a rock climbing-related injury, and more likely to undergo surgery for it. Female rock climbers were significantly more likely to report a shoulder/upper arm injury and were also more likely to report undergoing surgery compared with males, where these differences were not due to age or climbing behaviors. Further investigation is warranted into the association between shoulder injuries and female athletes to determine how the gender differences relate to extent of injury as well as health service utilization behaviors.

Ku, Chia-Hua; Radwin, Robert G; Karsh, Ben-Tzion

2007-06-01

This study investigated the relationship between pneumatic nutrunner handle reactions, workstation characteristics, and prevalence of upper limb injuries in an automobile assembly plant. Tool properties (geometry, inertial properties, and motor characteristics), fastener properties, orientation relative to the fastener, and the position of the tool operator (horizontal and vertical distances) were measured for 69 workstations using 15 different pneumatic nutrunners. Handle reaction response was predicted using a deterministic mechanical model of the human operator and tool that was previously developed in our laboratory, specific to the measured tool, workstation, and job factors. Handle force was a function of target torque, tool geometry and inertial properties, motor speed, work orientation, and joint hardness. The study found that tool target torque was not well correlated with predicted handle reaction force (r=0.495) or displacement (r=0.285). The individual tool, tool shape, and threaded fastener joint hardness all affected predicted forces and displacements (p<0.05). The average peak handle force and displacement for right-angle tools were twice as great as pistol grip tools. Soft-threaded fastener joints had the greatest average handle forces and displacements. Upper limb injury cases were identified using plant OSHA 200 log and personnel records. Predicted handle forces for jobs where injuries were reported were significantly greater than those jobs free of injuries (p<0.05), whereas target torque and predicted handle displacement did not show statistically significant differences. The study concluded that quantification of handle reaction force, rather than target torque alone, is necessary for identifying stressful power hand tool operations and for controlling exposure to forces in manufacturing jobs involving power nutrunners. Therefore, a combination of tool, work station, and task requirements should be considered.

The validity and clinical utility of the Disabilities of the Arm Shoulder and Hand questionnaire for hand injuries in developing country contexts: A systematic review.

PubMed

de Klerk, Susan; Buchanan, Helen; Jerosch-Herold, Christina

Systematic review. The Disabilities of the Arm Shoulder and Hand Questionnaire has multiple language versions from many countries around the world. In addition there is extensive research evidence of its psychometric properties. The purpose of this study was to systematically review the evidence available on the validity and clinical utility of the Disabilities of the Arm Shoulder and Hand as a measure of activity and participation in patients with musculoskeletal hand injuries in developing country contexts. We registered the review with international prospective register of systematic reviews prior to conducting a comprehensive literature search and extracting descriptive data. Two reviewers independently assessed methodological quality with the Consensus-Based Standards for the Selection of Health Measurement Instruments critical appraisal tool, the checklist to operationalize measurement characteristics of patient-rated outcome measures and the multidimensional model of clinical utility. Fourteen studies reporting 12 language versions met the eligibility criteria. Two language versions (Persian and Turkish) had an overall rating of good, and one (Thai) had an overall rating of excellent for cross-cultural validity. The remaining 9 language versions had an overall poor rating for cross-cultural validity. Content and construct validity and clinical utility yielded similar results. Poor quality ratings for validity and clinical utility were due to insufficient documentation of results and inadequate psychometric testing. With the increase in migration and globalization, hand therapists are likely to require a range of culturally adapted and translated versions of the Disabilities of the Arm Shoulder and Hand. Recommendations include rigorous application and reporting of cross-cultural adaptation, appropriate psychometric testing, and testing of clinical utility in routine clinical practice.

Effect of virtual reality distraction on pain among patients with hand injury undergoing dressing change.

PubMed

Guo, Chunlan; Deng, Hongyan; Yang, Jian

2015-01-01

To assess the effect of virtual reality distraction on pain among patients with a hand injury undergoing a dressing change. Virtual reality distraction can effectively alleviate pain among patients undergoing a dressing change. Clinical research has not addressed pain control during a dressing change. A randomised controlled trial was performed. In the first dressing change sequence, 98 patients were randomly divided into an experimental group and a control group, with 49 cases in each group. Pain levels were compared between the two groups before and after the dressing change using a visual analog scale. The sense of involvement in virtual environments was measured using the Pearson correlation coefficient analysis, which determined the relationship between the sense of involvement and pain level. The difference in visual analog scale scores between the two groups before the dressing change was not statistically significant (t = 0·196, p > 0·05), but the scores became statistically significant after the dressing change (t = -30·792, p < 0·01). The correlation between the sense of involvement in a virtual environment and pain level during the dressing was statistically significant (R(2) = 0·5538, p < 0·05). Virtual reality distraction can effectively alleviate pain among patients with a hand injury undergoing a dressing change. Better results can be obtained by increasing the sense of involvement in a virtual environment. Virtual reality distraction can effectively relieve pain without side effects and is not reliant on a doctor's prescription. This tool is convenient for nurses to use, especially when analgesics are unavailable. © 2014 John Wiley & Sons Ltd.

Mechanisms for anterior cruciate ligament injuries in badminton.

2010-12-01

A high incidence of anterior cruciate ligament (ACL) injuries related to sports activities has been reported; however, the injury situation of ACL injury in badminton has not been elucidated. This study investigated the mechanism of ACL injury in badminton using a questionnaire. Information on injury mechanism was gathered from interviews with six male and 15 female badminton players who received a non-contact ACL injury playing badminton and underwent ACL reconstruction. The most common injury mechanism (10 of 21 injuries) was single-leg landing after overhead stroke. Nine of 10 players had injured the knee opposite to the racket-hand side. The second most frequent injury mechanism (eight of 21 injuries) was plant-and-cut while side-stepping or backward stepping. All eight players injured the knee of the racket-hand side. Eleven injuries occurred in the rear court, and six of the 11 injuries occurred during single-leg landing after an overhead stroke. The knee opposite to the racket-hand side tended to sustain the ACL injuries during single-leg landing after a backhand overhead stroke, whereas the knee of the racket-hand side tended to be injured by plant-and-cut during side or backward stepping. These injury patterns appear to be due to specific movements during badminton.

Spacesuit Glove-Induced Hand Trauma and Analysis of Potentially Related Risk Variables

Injuries to the hands are common among astronauts who train for extravehicular activity (EVA). When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. Glove injuries, both anecdotal and recorded, have been reported during EVA training and flight persistently through NASA's history regardless of mission or glove model. Theories as to causation such as glove-hand fit are common but often lacking in supporting evidence. Previous statistical analysis has evaluated onycholysis in the context of crew anthropometry only. The purpose of this study was to analyze all injuries (as documented in the medical records) and available risk factor variables with the goal to determine engineering and operational controls that may reduce hand injuries due to the EVA glove in the future. A literature review and data mining study were conducted between 2012 and 2014. This study included 179 US NASA crew who trained or completed an EVA between 1981 and 2010 (crossing both Shuttle and ISS eras) and wore either the 4000 Series or Phase VI glove during Extravehicular Mobility Unit (EMU) spacesuit EVA training and flight. All injuries recorded in medical records were analyzed in their association to candidate risk factor variables. Those risk factor variables included demographic characteristics, hand anthropometry, glove fit characteristics, and training/EVA characteristics. Utilizing literature, medical records and anecdotal causation comments recorded in crewmember injury data, investigators were able to identify several risk factors associated with increased risk of glove related injuries. Prime among them were smaller hand anthropometry, duration of individual suited exposures, and improper glove-hand fit as calculated by the difference in the anthropometry middle finger length compared to the baseline EVA glove middle finger length.

There has been no comprehensive injury report of elite-level amateur boxers in competition and training. We reviewed injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2009. Longitudinal, prospective injury surveillance over 5 years of the GB boxing squad from 2005 to 2009. 66 boxers passed through the squad. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training, and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 h. More injuries affected the hand than any other body location. This was the case overall, in training and competition individually, and for both new and recurrent injuries. More injuries occurred during training than during competition, and most injuries were new rather than recurrent. Total injury rate during competition was 828 per 1000 h and hand injury rate in competition was 302 injuries per 1000 h. Hand injury rate in competition was significantly higher than at the other locations. The incidence of concussion is comparatively low. Injury prevention should aim to protect the hands and wrists of elite amateur boxers. Published by the BMJ Publishing Group Limited.

2013-01-01

To survey participants at various experience levels of different martial arts (MA) about upper extremity injuries sustained during training and fighting. A 21-s question survey was designed and utilised. The survey was divided into four groups (Demographics, Injury Description, Injury Mechanism, and Miscellaneous information) to gain knowledge about upper extremity injuries sustained during martial arts participation. Chi-square testing was utilised to assess for significant associations. Males comprised 81% of respondents. Involvement in multiple forms of MA was the most prevalent (38%). The hand/wrist was the most common area injured (53%), followed by the shoulder/upper arm (27%) and the forearm/elbow (19%). Joint sprains/muscle strains were the most frequent injuries reported overall (47%), followed by abrasions/bruises (26%). Dislocations of the upper extremity were reported by 47% of participants while fractures occurred in 39%. Surgeries were required for 30% of participants. Females were less likely to require surgery and more likely to have shoulder and elbow injuries. Males were more likely to have hand injuries. Participants of Karate and Tae Kwon Do were more likely to have injuries to their hands, while participants of multiple forms were more likely to sustain injuries to their shoulders/upper arms and more likely to develop chronic upper extremity symptoms. With advanced level of training the likelihood of developing chronic upper extremity symptoms increases, and multiple surgeries were required. Hand protection was associated with a lower risk of hand injuries. Martial arts can be associated with substantial upper extremity injuries that may require surgery and extended time away from participation. Injuries may result in chronic upper extremity symptoms. Hand protection is important for reducing injuries to the hand and wrist.

Patient-Reported Outcome Measures for Hand and Wrist Trauma

PubMed Central

Dacombe, Peter Jonathan; Amirfeyz, Rouin; Davis, Tim

2016-01-01

Background: Patient-reported outcome measures (PROMs) are important tools for assessing outcomes following injuries to the hand and wrist. Many commonly used PROMs have no evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. This systematic review examines the PROMs used in the assessment of hand and wrist trauma patients, and the evidence for reliability, validity, and responsiveness of each measure in this population. Methods: A systematic review of Pubmed, Medline, and CINAHL searching for randomized controlled trials of patients with traumatic injuries to the hand and wrist was carried out to identify the PROMs. For each identified PROM, evidence of reliability, validity, and responsiveness was identified using a further systematic review of the Pubmed, Medline, CINAHL, and reverse citation trail audit procedure. Results: The PROM used most often was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Patient-Rated Wrist Evaluation (PRWE), Gartland and Werley score, Michigan Hand Outcomes score, Mayo Wrist Score, and Short Form 36 were also commonly used. Only the DASH and PRWE have evidence of reliability, validity, and responsiveness in patients with traumatic injuries to the hand and wrist; other measures either have incomplete evidence or evidence gathered in a nontraumatic population. Conclusions: The DASH and PRWE both have evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. Other PROMs used to assess hand and wrist trauma patients do not. This should be considered when selecting a PROM for patients with traumatic hand and wrist pathology. PMID:27418884

Dentistry--a show of hands, please!

Rucker, Lance M

2007-01-01

Dentists have historically derived a distinctive part of their identity from the role of hand skills in practice. Dentistry is a surgical discipline, requiring a basic competency to perform what has been diagnosed and planned as being in the patients' best interests. Dental education has introduced magnification and computer-assisted technique instruction as the proportion of clock-hours devoted to laboratory practice has decreased. The threats posed by traumatic hand injury to practitioners are unknown, but may be small. By contrast, the strain of repetitive motion and injuries caused by postural problems are reported to be widespread in the profession and is generally accepted as characteristic and unavoidable. Ergonomic approaches to alleviating work strain have not been broadly embraced. As dentistry incorporates more biological alternatives and automated technology, the role of hands in practice may change.

Prevalence of cold sensitivity in patients with hand pathology.

The purpose of this study was to evaluate the prevalence of cold sensitivity in patients with hand- and wrist-related diagnoses. We included English-speaking adults who were more than 1 month following hand injury or onset of symptoms. Patients were asked if exposure to cold air or water provoked cold-related symptoms and to rank symptom severity (scale 0-10). Statistical analyses evaluated the relationships between the cold sensitivity and independent variables (age, gender, history of trauma, and time from injury/symptoms). There were 197 patients (mean age 49 ± 16 years): 98 trauma and 99 non-trauma cases. Cold-induced symptoms were reported by 34 %, with 10 % reporting severe symptoms. Exposure to cold air is the most common catalyst; mean severity score was 6.7 ± 2.2. Those with traumatic injuries compared to non-trauma diagnoses reported significantly more cold-induced symptoms (p = .04). Using backward linear regression, the significant predictors of cold symptom severity were trauma (p = .004) and time since onset (p = .003). Including only the trauma patients in the regression model, the significant predictor was time since injury (p = .005). Cold-induced symptoms are reported by more than 30 % of hand-related diagnoses, and exposure to cold air was the most commonly reported trigger. The significant predictors of cold-induced symptoms are traumatic injuries and longer time from injury. This study provides evidence of the common problem of cold sensitivity in patients with hand pathology. Prognostic Level II.

Robot-assisted training provides an effective approach to neurological injury rehabilitation. To meet the challenge of hand rehabilitation after neurological injuries, this study presents an advanced myoelectric pattern recognition scheme for real-time intention-driven control of a hand exoskeleton. The developed scheme detects and recognizes user's intention of six different hand motions using four channels of surface electromyography (EMG) signals acquired from the forearm and hand muscles, and then drives the exoskeleton to assist the user accomplish the intended motion. The system was tested with eight neurologically intact subjects and two individuals with spinal cord injury (SCI). The overall control accuracy was [Formula: see text] for the neurologically intact subjects and [Formula: see text] for the SCI subjects. The total lag of the system was approximately 250[Formula: see text]ms including data acquisition, transmission and processing. One SCI subject also participated in training sessions in his second and third visits. Both the control accuracy and efficiency tended to improve. These results show great potential for applying the advanced myoelectric pattern recognition control of the wearable robotic hand system toward improving hand function after neurological injuries.

Preventing penetrating hand injuries in sabre fencing: an application and critique of the van Mechelen model by the Fédération Internationale d'Escrime.

PubMed

Harmer, Peter A

2015-09-01

To address the unusual phenomenon of unbroken blades causing penetrating hand injuries in sabre fencing by applying the van Mechelen model of the 'sequence of prevention'. Cases were collected from three surveillance systems and snowball sampling, and examined for potential aetiological factors. Presumed contributing factors were evaluated against the available evidence to compile a viable list for change. Determining a prevention strategy was guided by the philosophy of developing an approach that was most likely to produce a meaningful reduction in these injuries with the least disruption to the current norms of competitive sabre fencing. Nine factors which contributed, either individually or in some combination, to these injuries were grouped under three headings relating to: (1) the nature of modern sabre fencing, (2) the design of the sabre blade and (3) the vulnerability of the hand. Changes to the design and integrity of sabre gloves were selected as the most feasible option and new standards were introduced as compulsory in international competitions from 1 April 2014. The effect of this change is now being monitored via available surveillance systems. The van Mechelen model is a useful framework for sports federations to apply to reduce injury risk, even for rare injuries. However, this research model has limitations in guiding the realities of sometimes competing interests among the scientific, political, financial and technical aspects of injury prevention interventions.

[Does the hand solely belong in the hands of a qualified hand surgeon?

PubMed

Güven, Asim; Kols, Kerstin; Fischer, Klaus; Schönberger, Michael; Allert, Sixtus

2017-09-01

Background In Germany, Hand Surgery is an additional qualification that can only be obtained by a three-year training after a completed residency in General Surgery, Plastic Surgery or Trauma and Orthopaedic Surgery. Nevertheless, injuries and diseases of the hand are also treated by physicians without this particular qualification. It is questionable whether these treatments more often lead to medical malpractice. Material and Methods 376 charges of medical malpractice in surgical treatments of the hand and forearm that were closed in 2014 and 2015 were collected by the Arbitration Board for Medical Liability Issues of the Medical Association of North Germany.Cases with proven medical malpractice were classified by the qualification of the physician in charge and analysed. A statistical analysis was performed with the use of the program SPSS (IBM). Results Medical malpractice was proven in 42 of 113 cases with an attending physician who held the additional qualification for Hand Surgery (37.2 %). For physicians without this qualification, the figures were 79 out of 155 (51.0 %) in the group of trauma and orthopaedic surgeons and 54 out of 108 (50.0 %) in the group of general surgeons. The differences between the hand surgeons and the trauma and orthopaedic surgeons (p = 0.017) and between hand surgeons and general surgeons were significant (p = 0.037). Conclusions It was shown that physicians with an additional qualification in hand surgery had signifcantly fewer proven medical malpratice cases than physicians without this qualification. The following trends were observed in the cases of the physicians without the additional qualification in hand surgery: underestimation of the severity of trauma to soft tissues and infections of the hand, errors in the surgical examination of the hand, including functional tests of tendons and nerves, as well as in diagnostic findings after X-ray studies of the hand.

2015-02-08

In his literary analysis, the author describes a novel method applied in the reconstruction of flexor tendon injuries of the hand. This procedure is named tissue engineering, and it is examined mainly under experimental circumstances. After definition of the method and descriptions of literary preliminaries the author discusses the healing process of the normal tendon tissue, then development of the scaffold, an important step of tissue engineering is described. After these topics the introduction of the pluripotent mesenchymal stem cells into the scaffold, and proliferation of these cells and development of the sliding systems are presented. The mechanical resisting ability of the formed tendon tissue is also discussed. Finally, the author concludes that as long as results of experimental research cannot be successfully applied into clinical practice, well-tried tendon reconstruction operations and high quality postoperative rehabilitation are needed.

Extravasation injuries occur under a wide variety of circumstances in the inpatient setting. Prevention remains the ideal treatment for these iatrogenic injuries. When extravasation injuries do occur, they must be diagnosed and treated promptly to minimize the amount of soft tissue injury. Initial management is similar among vesicant extravasates. Although evidence is limited to guide management for specific extravasates, it is paramount to be aware of the described treatments and principles.

Surgical exploration of hand wounds in the emergency room: Preliminary study of 80 personal injury claims.

PubMed

Mouton, J; Houdre, H; Beccari, R; Tarissi, N; Autran, M; Auquit-Auckbur, I

2016-12-01

The SHAM Insurance Company in Lyon, France, estimated that inadequate hand wound exploration in the emergency room (ER) accounted for 10% of all ER-related personal injury claims in 2013. The objective of this study was to conduct a critical analysis of 80 claims that were related to hand wound management in the ER and led to compensation by SHAM. Eighty claims filed between 2007 and 2010 were anonymised then included into the study. To be eligible, claims had to be filed with SHAM, related to the ER management of a hand wound in an adult, and closed at the time of the study. Claims related to surgery were excluded. For each claim, we recorded 104 items (e.g., epidemiology, treatments offered, and impact on social and occupational activities) and analysed. Of the 70 patients, 60% were manual workers. The advice of a surgeon was sought in 16% of cases. The most common wound sites were the thumb (33%) and index finger (17%). Among the missed lesions, most involved tendons (74%) or nerves (29%). Many patients had more than one reason for filing a claim. The main reasons were inadequate wound exploration (97%), stiffness (49%), and dysaesthesia (41%). One third of patients were unable to return to their previous job. Mean sick-leave duration was 148 days and mean time from discharge to best outcome was 4.19%. Most claims (79%) were settled directly with the insurance company, 16% after involvement of a public mediator, and 12% in court. The mean compensatory damages award was 4595Euros. Inadequate surgical exploration of hand wounds is common in the ER, carries a risk of lasting and sometimes severe residual impairment, and generates considerable societal costs. IV.

Microsurgical reconstruction of the severely mutilated hand aimed at improving prehensile functions often does not address the esthetic aspects of the hand. The poor appearance of the reconstructed hand affects its active display and use. A hand-glove prosthesis may be prescribed in this instance to enhance the overall form and function of the mutilated hand. We reviewed 16 cases of mutilating hand injuries in which surgical reconstructions were performed and the patients were subsequently fitted with a hand-glove prosthesis to augment the outcome. An improved appearance was achieved in all patients fitted with the prosthesis. The patients' sense of confidence was also enhanced, which in turn promoted the active and open use of the reconstructed hands. While prescribed primarily to improve the appearance of the reconstructed hands, these prostheses were documented to enhance the physical hand functions in 11 cases by increasing the span of the hand and providing an opposable post and a palmar base for holding and for anchorage. The prosthesis enhanced assistive functions of the reconstructed hands and freed the contralateral normal hand for use in bimanual activities, such as holding a wallet and taking out money, supporting a note pad for writing, and holding a plate at buffet receptions. At the 18-month follow-up visit, 13 (87%) of the patients continued to use their prosthesis. Wear and tear were problems associated with the frequent use of the prosthesis. The expected life span of the prosthesis with daily use ranged from 2 to 3 years. All the patients acknowledged that the prosthesis played a role in their rehabilitation and that it helped them to overcome the initial psychological trauma and to come to terms with their physical loss.

Many stroke and spinal cord injury patients suffer from paralysis which range from severe to nominal. Some of them, after therapy, could regain most of the motor control, particularly in hands if the severity level is not so high. In this paper we propose a hand orthosis for such patients whose stroke and spinal cord injury severity is nominal and the motor control in hands can be regained by therapy as part of their rehabilitation process. The patients can wear this orthosis and the therapy can be done with simple Human Computer Interface. The physicians, the physiotherapists and the patients themselves can carry out the therapy with the help of this device. The tests conducted in the lab and the results obtained are very promising that this can be an effective mechanism for stroke and spinal cord injury patients in their rehabilitation process. The hand orthosis is designed and fabricated locally so that it can be made available to such patients at an affordable cost.

Biofeedback training is widely used for rehabilitative intervention in patients with central or peripheral nervous impairment to train correct movement patterns; however, no biofeedback apparatus is currently available to correct pinch force ratios for patients with sensory deficiencies. A cross-sectional and longitudinal design was used in an observational measurement study for establishing a prototype and to determine the effects of biofeedback intervention, respectively. This study aimed to develop a computerized evaluation and re-education biofeedback (CERB) prototype for application in clinical settings. A CERB prototype was developed integrating pinch apparatus hardware, a biofeedback user-controlled interface, and a data processing/analysis interface to detect momentary pinch performances in 79 people with normal hand sensation. Nine patients with hand sensory impairments were recruited to investigate the effects of training hand function with the CERB prototype. Hand dominance, pinch pattern, and age significantly affected the peak pinch force and force ratio for lifting a 480-g object with a steel surface. In the case of the 79 volunteers with normal hand sensation, hand dominance affected the time lag between peak pinch force and maximum load; however, it was unaffected by pinch pattern or age. Training with the CERB prototype produced significant improvements in force ratio and better performance in the pin insertion subtests, although the results for both 2-point discriminative and Semmes-Weinstein monofilament tests did not change significantly. The intervention findings are preliminary. This study developed a conjunct system suited for evaluating and restoring sensorimotor function for patients with impaired hand sensibility. The results from the participants with normal hand sensation could serve as a reference database for comparison with patients with nerve injuries.

Fourth-degree hand burns are rare but devastating injuries. They cannot be grafted readily but often require flaps and amputation, and impairment is significant. We report our 10-year experience (1981 to 1990) with deep hand burns to characterize our treatment and outcome. A total of 25 patients (35 hands) were treated. Eight local flaps, nine distant flaps, and two free-tissue transfers were performed. Eleven hands were treated with K-wire immobilization and grafting. Thirty-three amputations were done. Postburn function was evaluated in 25 salvaged hands. Eleven hands had good outcomes, whereas seven had moderate sequelae and seven were severely affected. Patients who were treated with flap coverage of exposed tendons and joints had better functional outcomes than those treated with delayed closure with immobilization and grafting. The excellent outcomes in the flap coverage group justifies the added commitment of technical and therapeutic resources that this treatment requires.

The aim of this study was to determine the differences in the anatomical site of a gunshot entrance wound and the direction of the bullet path between right- and left-handed subjects who committed a suicide by a single gunshot injury to the head. The retrospective autopsy study was performed for a 10-year period, and it included selected cases of single suicidal gunshot head injury, committed by handguns. We considered only contact or near-contact wounds. The sample included 479 deceased, with average age 47.1 ± 19.1 years (range, 12-89 years): 432 males and 47 females, with 317 right-handed, 25 left-handed, and 137 subjects with unknown dominant hand. In our observed sample, most cases involved the right temple as the site of entrance gunshot wound (about 67%), followed by the mouth (16%), forehead (7%), left temple (6%), submental (2%), and parietal region (1%). The left temple, right temple, and forehead were the sites of the gunshot entrance wounds, which were the best predictors of the handedness of the deceased (Spearman ρ = 0.149, P = 0.006). Our study showed that the direction of the bullet intracranial path in cases of suicide was even a more potent predictor of the handedness of the deceased (Spearman ρ = 0.263, P = 0.000; Wald = 149.503, P = 0.000).

This study reports three cases of ulnar neuropathy after trampoline injuries in children. A chart review was performed on children who sustained an ulnar nerve injury from a trampoline accident. In all cases, surgical intervention was required. Injuries included upper-extremity fractures in two cases and an upper-extremity laceration in one case. All cases required surgical exploration with internal neurolysis and ulnar nerve transposition. Nerve grafts were used in two cases and an additional nerve transfer was used in one case. All patients had return of intrinsic hand function and sensation after surgery. Children should be followed for evolution of ulnar nerve neuropathy after upper-extremity injury with consideration for electrical studies and surgical exploration if there is no improvement after 3 months.

Human hands play a significant role during extravehicular activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. It is because of this high frequency usage that hand- and arm-related injuries and discomfort are known to occur during training in the NBL and while conducting EVAs. Hand-related injuries and discomforts have been occurring to crewmembers since the days of Apollo. While there have been numerous engineering changes to the glove design, hand-related issues still persist. The primary objectives of this study are therefore to: 1) document all known EVA glove-related injuries and the circumstances of these incidents, 2) determine likely risk factors, and 3) recommend ergonomic mitigations or design strategies that can be implemented in the current and future glove designs. METHODS: The investigator team conducted an initial set of literature reviews, data mining of Lifetime Surveillance of Astronaut Health (LSAH) databases, and data distribution analyses to understand the ergonomic issues related to glove-related injuries and discomforts. The investigation focused on the injuries and discomforts of U.S. crewmembers who had worn pressurized suits and experienced glove-related incidents during the 1980 to 2010 time frame, either during training or on-orbit EVA. In addition to data mining of the LSAH database, the other objective of the study was to find complimentary sources of information such as training experience, EVA experience, suit-related sizing data, and hand-arm anthropometric data to be tied to the injury data from LSAH. RESULTS: Past studies indicated that the hand was the most frequently injured part of the body during both EVA and NBL training. This study effort thus focused primarily on crew training data in the NBL between 2002 and 2010. Of the 87 recorded training incidents, 19 occurred to women and 68 to men. While crew ages ranged from

We tested the hypothesis that somatosensory system injury would more strongly affect movement than motor system injury in children with unilateral cerebral palsy (USCP). This hypothesis was based on how somatosensory and corticospinal circuits adapt to injury during development; whereas the motor system can maintain connections to the impaired hand from the uninjured hemisphere, this does not occur in the somatosensory system. As a corollary, cortical injury strongly impairs sensory function, so we hypothesized that cortical lesions would impair hand function more than subcortical lesions. Twenty-four children with unilateral cerebral palsy had physiological and anatomical measures of the motor and somatosensory systems and lesion classification. Motor physiology was performed with transcranial magnetic stimulation and somatosensory physiology with vibration-evoked electroencephalographic potentials. Tractography of the corticospinal tract and the medial lemniscus was performed with diffusion tensor imaging, and lesions were classified by magnetic resonance imaging. Anatomical and physiological results were correlated with measures of hand function using 2 independent statistical methods. Children with disruptions in the somatosensory connectivity and cortical lesions had the most severe upper extremity impairments, particularly somatosensory function. Motor system connectivity was significantly correlated with bimanual function, but not unimanual function or somatosensory function. Both sensory and motor connectivity impact hand function in children with USCP. Somatosensory connectivity could be an important target for recovery of hand function in children with USCP.

The number of injuries caused by power tools is steadily increasing as more domestic woodwork is undertaken and more power tools are used recreationally. The injuries caused by the different power tools as a consequence of accidents are an issue, because they can lead to substantial costs for patients and the national insurance system. The increase in hand surgery as a consequence of the use of power tools and its economic impact, and the characteristics of the hand injuries caused by power saws have been described. In recent years, the authors have noticed that, in addition to hand injuries, facial injuries caused by power tools commonly present to the emergency room. This study aimed to review the data in relation to facial injuries caused by power saws that were gathered from patients who visited the trauma center at our hospital over the last 4 years, and to analyze the incidence and epidemiology of the facial injuries caused by power saws. The authors found that facial injuries caused by power tools have risen continually. Facial injuries caused by power tools are accidental, and they cause permanent facial disfigurements and functional disabilities. Accidents are almost inevitable in particular workplaces; however, most facial injuries could be avoided by providing sufficient operator training and by tool operators wearing suitable protective devices. The evaluation of the epidemiology and patterns of facial injuries caused by power tools in this study should provide the information required to reduce the number of accidental injuries.

The aim of the study was to delineate and update the bacteriological spectrum, characterize patterns and sites of injury, evaluate laboratory tests and possible causes of complications in patients with bacterial hand infections. All hand infections operated on in the department of orthopedics at Odense University Hospital during the period 1992-2001 were reviewed retrospectively. A standard protocol was used to collect data for each patient. We also examined all laboratory reports and recorded the identity of the etiologic organism, if known, for all cases of bacterial hand infections. Four hundred and eighteen patients (296 men and 122 women) with hand infections were operated on between 1992 and 2001 in our department. The median age of the patients was 40 years (range 1-93). The average interval from primary injury to operation was 10 days (range 1-50). The etiology was laceration/puncture in 35%. The site of infection was subcutaneous in 45% followed by tendon, joint and bone in 27, 18 and 5%, respectively. The bacteria isolated from the patients showed that 184 cultures (44%) were pure Staphylococcus aureus followed by 49 cultures (11.7%) of mixed organisms. Body temperature and C-reactive protein (CRP) were normal in three quarters of all patients with hand infections in our series. However the erythrocyte sedimentation rate (ESR) was elevated in 50% of the patients and was a significantly better test for infection in this study than CRP (p = 0.002). Neither the severity of infection nor the etiology of infection was related in any way to the initial temperature, CRP or ESR in this study. Complications were noted in 14.8% of all patients, and were especially related to diabetes, and mixed infection. Despite modern antibiotics, hand infections with a variety of organisms continue to be a source of morbidity and possible long-term disability. Most hand infections are the result of minor wounds that have been neglected. A complete history and physical

To validate the psychometric properties of the questionnaire on hand function assessment in leprosy. Study conducted with a convenience sample of 101 consecutive patients in Brasília (Central-Western Brazil), from June 2008 to July 2009. The individuals were adults affected by leprosy, with impairment of the ulnar, median and radial nerves. Interobservers and intraobserver reproducibility was analyzed through successive interviews, and construct validity was analyzed through association between age, clinical form of leprosy, duration of nerve injury, grip and pinch strength measured with a dynamometer, sensibility test performed with Semmes-Weinstein monofilaments and manual ability assessment using the Jebsen test of hand function. Pondered kappa coefficient was calculated and a Bland-Altman plot was constructed to assess the reproducibility of the instrument. For internal consistency, Cronbach's alpha coefficient was utilized. Pearson's correlation coefficient was calculated and a multiple regression model was used. The pondered kappa values for interobservers and intraobserver assessments ranged from 0.86 to 0.97 and from 0.85 to 0.97, respectively. The value of Cronbach's alpha coefficient was 0.967. Pearson's correlation coefficient showed an association (p < 0.001) among duration of nerve injury, grip and pinch strength, cutaneous sensibility and mean score in the Jebsen Test. The mean score of the questionnaire on hand functional assessment in leprosy was associated with operational classification of leprosy, duration of nerve injury, grip strength, cutaneous sensibility and manual ability (p < 0.0001 for the model as a whole). The questionnaire on hand functional assessment in leprosy presents almost perfect interobservers and intraobserver reproducibility, high internal consistency and correlation with operational classification of leprosy, duration of nerve injury, grip strength, cutaneous sensibility in the hands and manual ability.

To investigate whether a Chinese herbal medicine, erigeron breviscapus (vant) hand-mazz (EBHM), can protect the retinal ganglion cells (RGC) damaged by calibrated optic nerve crush injury. Forty-two Sprague-Dawley rats were randomly divided into two groups. Calibrated optic nerve crush injury model was induced in the right eyes by a special designed optic nerve clip. The left eyes served as a control. All 42 rats were randomly divided into 2 groups. Group A consisted of the rats with calibrated optic nerve crush injury and group B consisted of rats with calibrated optic nerve crush injury treated with EBHM. In group B, EBHM solution was given once after the crush injury. According to the time interval between the optic nerve crush and the sacrifice, both groups A and B were further divided into three subgroups (day 4, day 14 and day 21). Therefore, there were 7 rats in each subgroup. Three days before sacrifice, 3% fast blue was injected into superior colliculi bilaterally. The eyes were enucleated after the rat was sacrificed, and flat mounts of the retina from both eyes were prepared on a slide and observed under a fluorescence microscope. Four photos with 400 x magnification were taken from each of the four quadrants of the retina 1 mm away from the optic disc. The labeled RGC were counted by a computerized image analyzer. The labeled RGC rate was used for statistical analysis (the labeled RGC rate = number of RGC in injured eye/control eye x 100%). In group A, the labeled RGC rate was (77.79 +/- 7.11)%, (63.76 +/- 3.79)% and (54.66 +/- 4.75)% on day 4, day 14 and day 21, respectively. In group B, the labeled RGC rate was (80.13 +/- 12.03)%, (78.17 +/- 9.19)% and (83.59 +/- 12.61)% on day 4, day 14 and day 21, respectively. In group B, which was treated with EBHM after injury, the labeled RGC rate was significantly higher than that of group A on day 14 and day 21. In the experimental optic nerve crush model in rats, EBHM therapy can increase the survival rate of

Hand-arm vibration syndrome (HAVS) has been associated with prolonged exposure to vibration transmitted to the human hand-arm system from hand-held power tools, vibrating machines, or hand-held vibrating workpieces. The biodynamic response of the human hand and arm to hand transmitted vibration (HTV) forms an essential basis for effective evaluations of exposures, vibration-attenuation mechanisms, and potential injury mechanisms. The biodynamic response to HTV and its relationship to HAVS are critically reviewed and discussed to highlight the advances and the need for further research. In view of its strong dependence on the nature of HTV and the lack of general agreement on the characteristics of HTV, the reported studies are first reviewed to enhance an understanding of HTV and related issues. The characteristics of HTV and relevant unresolved issues are discussed on the basis of measured data, proposed standards, and measurement methods, while the need for further developments in measurement systems is emphasized. The studies on biodynamic response and their findings are grouped into four categories based on the methodology used and the objective. These include studies on (1) through-the-hand-arm response, expressed in terms of vibration transmissibility; (2) to-the-hand response, expressed in terms of the force-motion relationship of the hand-arm system; (3) to-the-hand biodynamic response function, expressed in terms of vibration energy absorption; and (4) computer modeling of the biodynamic response characteristics.

Previously, we showed that the ventral premotor cortex (PMv) underwent neurophysiological remodeling after injury to the primary motor cortex (M1). In the present study, we examined cortical connections of PMv after such lesions. The neuroanatomical tract tracer biotinylated dextran amine was injected into the PMv hand area at least 5 months after ischemic injury to the M1 hand area. Comparison of labeling patterns between experimental and control animals demonstrated extensive proliferation of novel PMv terminal fields and the appearance of retrogradely labeled cell bodies within area 1/2 of the primary somatosensory cortex after M1 injury. Furthermore, evidence was found for alterations in the trajectory of PMv intracortical axons near the site of the lesion. The results suggest that M1 injury results in axonal sprouting near the ischemic injury and the establishment of novel connections within a distant target. These results support the hypothesis that, after a cortical injury, such as occurs after stroke, cortical areas distant from the injury undergo major neuroanatomical reorganization. Our results reveal an extraordinary anatomical rewiring capacity in the adult CNS after injury that may potentially play a role in recovery.

SYNOPSIS Football and rugby athletes are at increased risk of finger injuries given the full contact nature of these sports. Depending on the injury and the position played, some players may return to play early with protective taping, splinting, and casting. Other injuries, particularly in players requiring the full use of their hand for their position, require a longer rehabilitation period and prolonged time away from the field. The treating hand surgeon must carefully weigh the benefits of early return to play for the athlete’s current season and future playing career against the risks of re-injury and long-term morbidity, including post-traumatic arthritis and decreased range of motion and strength. Each player must be comprehensively assessed and managed with an individualized treatment plan. PMID:27886831

Hands are the most commonly burnt body part given humans' innate response to guard their face from injury, and are known to have detrimental functional and psychological consequences. Conflicting evidence exists regarding the impact of hand burns on long-term health status and global functioning. The objective of this study was to identify patient and clinical characteristics that predict health status and hand function of people at 12-24 months after hand burn. The Burns Specific Health Scale-Brief (BSHS-B) and the Brief Michigan Hand Outcome Questionnaire (Brief MHQ) were administered to community-dwelling adults who were between one and two years after admission to a statewide burns service for burns including one or both hands. Demographic, injury, and treatment data were collected to identify which factors predict health status and hand function in the second year after admission. Linear regression analyses adjusted for total burn surface area and burn depth were conducted to identify important predictors or outcomes. The sample (n=41) was 80.5% male, with a mean age of 44.5 years and total body surface area (TBSA) of 8.4%. Psychiatric illness (regression coefficient -56.6, confidence interval (95% CI) -76.70, -36.49) and female gender (-20.3; 95% CI -0.77, -40.29) were key predictors of poorer global health status on the BSHS-B. Females also scored worse on body image (-5.35; 95% CI -1.83, -8.87) and work (-4.13; 95% CI -0.64, -7.62) domains of BSHS-B. The need for reconstructive or secondary surgery (-38.84; 95% CI -58.04, -19.65) and female gender (-16.30; 95% CI -4.03, -28.57) were important predictors of poorer hand function. Women and those with a history of psychiatric illness are particularly vulnerable to poorer outcomes in health status and/or hand function after burns, and may benefit from more intensive rehabilitation support and long-term follow-up.

Hand injuries are very common in sports, such as skiing and ball sports. One of the major reasons causing hand and finger deformity is due to ligament and tendon injury. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) can demonstrate the complex anatomy of the fingers and thumb, especially the tendons and ligaments, and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport activities. Sixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers. A total of 20 healthy volunteers' hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this study. All subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression (PD FS) in axial, coronal, and sagittal plane, respectively. Subsequently, all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw (six in coronal plane, six in sagittal plane, and four in axial plane). The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament (UCL) at the metacarpal phalangeal joint (MCPJ) of thumb between 20 healthy volunteers and 44 patients (confirmed by surgery) were analyzed. The normal ligaments and tendons in 16 cadaveric hands and 20 volunteers' hands showed uniform low-signal intensity on all the sequences of the MRI. Among 44 patients with tendinous and ligamentous injuries in the fingers or thumb, 12 cases with UCL injury at MCPJ of the thumb (Stener lesion = 8 and non-Stener lesion = 4), 6 cases with the central slip injury, 12 cases with terminal tendon injury, and 14 cases with flexor digitorum profundus injury. The ligaments and tendons disruption manifested as increased signal intensity and poor definition, discontinuity, and heterogeneous signal intensity of the involved ligaments and tendons. Sports

Hand and foot burns in children are difficult to dress. The authors have developed a soft casting technique to manage burns to these areas. The aim of this study is to report the outcomes using weekly dressing changes with a soft casting technique to manage pediatric hand and foot burns in the outpatient setting. A retrospective chart review was performed on children with burns to the hands or feet, who underwent dressing changes with a soft casting technique at the Children's Hospital Colorado Burn Center. Soft casting was performed by placing antibiotic ointment-impregnated nonadherent gauze over the burn wound(s), wrapping the extremity using rolled gauze, applying soft cast pad, plaster, soft cast tape, and an elastic bandage. This was changed weekly. Two hundred ninety-eight children with hand burns had a mean age of 16.8 ± 2 months. Two hundred forty-eight children had partial thickness burn injuries (83%), 50 had full thickness burn injuries (17%), and the mean total body surface area (TBSA) was 1 ± 2.4%. The mean time to heal was 10.1 ± 1.7 days for all subjects. Sixty-six children with foot burns were identified with a mean age of 24 ± 2.6 months. Forty-six children had partial thickness injuries (70%), 20 had full thickness burn injuries (30%), and the mean TBSA was 2.3 ± 2.9%. The mean time to heal was 14.1 ± 2.2 days for all subjects. Weekly dressing changes using a soft casting technique are effective for the outpatient management of pediatric hand and foot burns. This method avoids costly inpatient hospital care, reduces the number of painful dressing changes, and allows children to heal in their own environment.

BACKGROUND: Astronaut spacewalk training can result in a variety of symptom complaints and possible injuries. This study quantified and characterized signs, symptoms, and injuries resulting from extravehicular activity spacesuit training at NASA's Neutral Buoyancy Laboratory, Johnson Space Center, Houston, TX, immersion facility. METHODS: We identified the frequency and incidence of symptoms by location, mechanisms of injury, and effective countermeasures. Recommendations were made to improve injury prevention, astronaut training, test preparation, and training hardware. At the end of each test, a questionnaire was completed documenting signs and symptoms, mechanisms of injury, and countermeasures. RESULTS: Of the 770 tests, there were 190 in which suit symptoms were reported (24.6%). There were a total of 352 reported suit symptom comments. Of those symptoms, 166 were in the hands (47.16%), 73 were in the shoulders (20.7%), and 40 were in the feet (11.4%). Others ranged from 6.0% to 0.28%, respectively, from the legs, arms, neck, trunk, groin, and head. Causal mechanisms for the hands included moisture and hard glove contacts resulting in fingernail injuries; in the shoulders, hard contact with suit components and strain mechanisms; and in the feet, hard boot contact. The severity of symptoms was highest in the shoulders, hands, and feet. CONCLUSIONS: Most signs and symptoms were mild, self-limited, of brief duration, and were well controlled by available countermeasures. Some represented the potential for significant injury with consequences affecting astronaut health and performance. Correction of extravehicular activity training-related injuries requires a multidisciplinary approach to improve prevention, medical intervention, astronaut training, test planning, and suit engineering.

The severity of symptoms was highest in the shoulders, hands, and feet. Most signs and symptoms were mild, self-limited, of brief duration, and were well controlled by available countermeasures. Some represented the potential for significant injury with consequences affecting astronaut health and performance. Correction of extravehicular activity training-related injuries requires a multidisciplinary approach to improve prevention, medical intervention, astronaut training, test planning, and suit engineering.

[The plexal hand (involvement of the hand in traumatic lesions of the brachial plexus in adults)].

Alnot, J Y; Salon, A

After spontaneous recovery following brachial plexus injuries, or after nerve regeneration following nervous surgery on traumatic brachial plexus, there usually is a variable residual distal deficit involving the hand and wrist. This deficit is defined by both a functional approach, and its anatomical nervous correspondence, in order to predict which motor muscles will be available for palliative surgery, and to establish the most reasonable therapeutic plan. Total palsy of the hand will only be mentioned, whereas three main presentations of the "plexic hand" are of a greater surgical interest and will be detailed: the "wrist drop", due to C5 C6 +/- C7 supra-clavicular lesions, the hand presenting with a deficit of digit flexion, pinch and intrinsic functions, due to C8 T1 +/- C7 supra-clavicular lesions, non-standardized deficits due to infra- and retro-clavicular lesions, whose therapeutic indications and prognosis are closer to more classical trunk palsies. The review of 44 "plexic hands" after distal palliative surgery indicates the need to modify the fundamental rules of tendinous transfer surgery, and suggests new principles properly adapted to the surgery of plexic hand palsies.

The severity of the injury is the most important factor to return to work (RTW) when it comes to hand injuries. The purpose of our study is to examine the relationship between the initial anatomic severity, evaluated by the Hand Injury Severity Scoring (HISS) system, and probability of RTW in occupational hand injured patients. In this retrospective cohort study, 140 patients hospitalized for surgery due to occupational hand injuries between 2004 and 2008 were recruited. Participants were interviewed for occupational history and RTW status. The probability of RTW was compared with the initial HISS scores by multiple logistic regression models. In workers' compensation group, there was a significant relationship between HISS severity and the probability of RTW. Compensated patients with moderate injuries (odds ratio [OR] = 0.15; 95% confidence interval [CI], 0.03-0.70) and severe injuries (OR = 0.13; 95% CI, 0.02-0.75) were significantly less likely to RTW than those with minor injuries, and those with major injuries were the least likely to RTW (OR = 0.07; 95% CI, 0.01-0.36). However, no association was found between HISS severity and the probability of RTW for patients without workers' compensation. With regard to the HISS components, patients with motor or neural component deficits had a significantly lower opportunity of RTW, with the neural deficits being the most influential. HISS is a useful instrument to predict the opportunity of RTW while restricted to the compensated patients. We also verified that the relationship between HISS severity and the probability of RTW existed for groups but not for individual patients.

Paralysis of the upper limbs from spinal cord injury results in an enormous loss of independence in an individual's daily life. Meaningful improvement in hand function is rare after 1 year of tetraparesis. Therapeutic developments that result in even modest gains in hand volitional function will significantly affect the quality of life for patients afflicted with high cervical injury. The ability to neuromodulate the lumbosacral spinal circuitry via epidural stimulation in regaining postural function and volitional control of the legs has been recently shown. A key question is whether a similar neuromodulatory strategy can be used to improve volitional motor control of the upper limbs, that is, performance of motor tasks considered to be less "automatic" than posture and locomotion. In this study, the effects of cervical epidural stimulation on hand function are characterized in subjects with chronic cervical cord injury. Herein we show that epidural stimulation can be applied to the chronic injured human cervical spinal cord to promote volitional hand function. Two subjects implanted with a cervical epidural electrode array demonstrated improved hand strength (approximately 3-fold) and volitional hand control in the presence of epidural stimulation. The present data are sufficient to suggest that hand motor function in individuals with chronic tetraplegia can be improved with cervical cord neuromodulation and thus should be comprehensively explored as a possible clinical intervention. © The Author(s) 2016.

Martial arts injuries.

To review the current evidence for the epidemiology of pediatric injuries in martial arts. The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure. Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

We estimated costs associated with injuries to hands from log splitters and circular saws used to cut up firewood and assessed the value of prevention. The study was carried out as a cost of illness study with an incidence approach based on 57 consecutive patients (median age 51; range 8-81) with injuries to the hand or forearm. Twenty-six of the 57 had an amputation which required microsurgery and 31/57 had various injuries. Median Hand Injury Severity Score (HISS) reflecting the severity of all injuries was 67 (range 6-332). Median DASH score after 2-7 years was 12.5 (0-73.3). Total cost (direct costs, costs of lost productivity, and lost quality of life) was estimated to roughly EUR 14 million (EUR 2.8 million/year), where the cost of lost quality of life is 82% of the total cost and loss of productivity and direct costs are 9% each. Injuries sustained from log splitters and circular saws account for considerable costs, but first and foremost human suffering.

The purpose of this study was to assess the prevalence, distribution, severity, risk factors of, and response to musculoskeletal injuries to the low back, hand/wrist, and neck/shoulder among chiropractic students while receiving and/or administering adjustments/manipulation while attending a chiropractic college. The study was an epidemiologic survey of chiropractic students at all levels of training (n = 890) at one chiropractic college. A self-administered anonymous 3-paged questionnaire was used. The questionnaire was divided into sections for collecting data separately on injuries associated with receiving or administering chiropractic adjustments. The response rate was 64.3% with 62.6% male respondents. The overall prevalence of injuries sustained in college was 31.5%, 44.4% of which was exacerbations of prior complaints. Injuries from receiving adjustments/manipulation were most prevalent to neck/shoulder (65.7%), whereas hand/wrist injuries were most common when administering adjustments (45.6%). The risk difference among students receiving adjustments was 81.6/1000 neck/shoulder injuries, and the etiologic fraction was 76.6%. The risk difference was 170/1000 hand/wrist injuries with etiologic fraction of 96.5% among students administering adjustments. Diversified, Gonstead, and upper cervical adjusting techniques were perceived to be the most injury-related. Some students enroll in a chiropractic college with preexisting injuries that can easily be exacerbated. Others sustain new injuries of moderate severity from receiving and administering adjustments. Potential risk factors may include height, body mass index, and nonexercising. The risk factors and mechanisms responsible for the high levels of hand/wrist injuries need further examination. This research identifies an important need to design a comprehensive and logical protocol to prevent injury to chiropractic students.

Sensory evaluations are frequently used to assess patients with functional loss resulting from nerve injury. The results of these tests are routinely utilized by hand surgeons as an indication for conservative management or surgical intervention in the evaluation of surgical outcome and in the determination of disability ratings. Reports in the literature regarding specific tests for sensibility show variation in their application. The purpose of this study was to evaluate which tests are used to evaluate hand sensibility and the techniques of application currently used by hand therapists. Two hundred members of the American Society of Hand Therapists were randomly selected and a survey was sent to these members. The results of this study identify the need to develop standardized protocols for sensory evaluations and the need for therapists to follow the standardized methods for administration of moving and static two-point discrimination, and Semmes-Weinstein monofilaments, if comparisons of results between centers are to be meaningful.

Firework related injury and legislation: the epidemiology of firework injuries and the effect of legislation in Northern Ireland.

Fogarty, B J; Gordon, D J

1999-02-01

The efficacy of legislation in reducing firework associated injuries is uncertain as is the nature of the problem within the United Kingdom (UK). In September 1996 the legislation governing firework sale in Northern Ireland was relaxed thus equalling that of the rest of the UK. For the 2 years following the change in legislation we prospectively assessed those patients who were admitted with a firework injury over the Halloween period. We then compared these results with retrospective data for the 3 years prior to the change in firework law. In the pre-legislation series the mean number of patients admitted annually was 0.38 per 100,000 while in the post-legislation series the mean was 0.43 per 100,000. Blast injury to the hand was the commonest injury accounting for 53% of cases in both series. Burn injuries were the second commonest form of injury comprising 30% of all admissions. Of those admitted with a hand injury 47% had at least one finger terminalised and nearly half of those patients admitted with burns (44%) required skin grafting. We conclude that early evidence suggests that liberalisation of the law on firework sale has not resulted in a significant increase in firework related injuries requiring hospital admission.

We report a previously unrecognized hand dermatosis, pulling boat hands (PBH), occurring in thirteen participants at the Outward Bound School on Hurricane Island, Maine. Painful and pruritic macules, plaques, and vesicles developed exclusively while subjects lived aboard a pulling boat, the school's open rowing/sailing craft. Nine of those affected were women and eight had Raynaud's phenomenon or vasospasm. These subjects experienced thirty episodes of PBH during May through October, 1978 to 1982. Histopathology revealed a superficial and deep lymphohistiocytic perivascular infiltrate, subepidermal blister formation, red blood cell extravasation, and dermal capillary thrombosis compatible with cold injury to the skin. All patients experienced prolonged percussion to their hands while rowing as well as a continuous environmental exposure to cold air, wind, humidity, ocean spume, and precipitation. These clinical, histopathologic, and environmental findings suggest a unique syndrome that combines the vascular effects of mechanical trauma from rowing with those of nonfreezing cold injury.

Obstetric brachial plexus injury

Obstetric brachial plexus injury (OBPI), also known as birth brachial plexus injury (BBPI), is unfortunately a rather common injury in newborn children. Incidence varies between 0.15 and 3 per 1000 live births in various series and countries. Although spontaneous recovery is known, there is a large subset which does not recover and needs primary or secondary surgical intervention. An extensive review of peer-reviewed publications has been done in this study, including clinical papers, review articles and systematic review of the subject. In addition, the authors’ experience of several hundred cases over the last 15 years has been added and has influenced the ultimate text. Causes of OBPI, indications of primary nerve surgery and secondary reconstruction of shoulder, etc. are discussed in detail. Although all affected children do not require surgery in infancy, a substantial proportion of them, however, require it and are better off for it. Secondary surgery is needed for shoulder elbow and hand problems. Results of nerve surgery are very encouraging. Children with OBPI should be seen early by a hand surgeon dealing with brachial plexus injuries. Good results are possible with early and appropriate intervention even in severe cases. PMID:22279269

Powerlifting is a discipline of competitive weightlifting. To date, no investigations have focused on pain encountered during routine training. The aim of the study was to identify such pain, assign it to particular exercises and assess the data regarding injuries as well as the influence of intrinsic and extrinsic factors. Data of 245 competitive and elite powerlifters was collected by questionnaire. Information regarding current workout routines and retrospective injury data was collected. Study subjects were selected from 97 incorporated powerlifting clubs. A percentage of 43.3% of powerlifters complained of problems during routine workouts. Injury rate was calculated as 0.3 injuries per lifter per year (1 000 h of training=1 injury). There was no evidence that intrinsic or extrinsic factors affected this rate. Most commonly injured body regions were the shoulder, lower back and the knee. The use of weight belts increased the injury rate of the lumbar spine. Rate of injury to the upper extremities was significantly increased based on age >40 years (shoulder/p=0.003, elbow/p=0.003, hand+wrist/p=0.024) and female gender (hand+wrist/p=0.045). The daily workout of a large proportion of powerlifters is affected by disorders which do not require an interruption of training. The injury rate is low compared to other sports. © Georg Thieme Verlag KG Stuttgart · New York.

Acute common peroneal neuropathy due to hand positioning in normal labor and delivery.

Radawski, Melissa M; Strakowski, Jeffrey A; Johnson, Ernest W

2011-08-01

Foot drop has been described as an infrequent complication from common peroneal nerve injury related to external compression and forceful knee flexion while pushing during vaginal delivery. Past recommendations include placing the hands at the posterior thighs rather than the legs to avoid this complication. A 32-year-old woman developed unilateral foot drop after vaginal delivery. Electromyography was diagnostic for an acute compression neuropathy of the common peroneal nerve above the knee. The patient's likely mechanism of injury occurred during delivery from external compression by the patient's dominant hand to the distal posterior thigh while under epidural anesthesia. Labor and delivery teams should be aware that nerve injury is also possible at the distal thigh with excessive external pressure.

Objective: To describe the epidemiology of work related injury in a group of small scale, independent commercial fishers. Design: Cross sectional survey (baseline instrument of a prospective cohort study). Setting and subjects: Commercial fishers in eastern North Carolina. Results: A cohort of 219 commercial fishers was established and 215 subjects completed an injury questionnaire. The main types of fishing conducted by the cohort were finfishing (159/215) and crabbing (154/215). Of the 215 fishers, 83 reported that they had suffered an injury event in the previous 12 months, a retrospective recall incidence proportion of 38.6 per 100 workers (95% confidence interval 32.1 to 45.1). The 83 injury events resulted in 94 injuries; 47% were penetrating wounds and 24% were strains/sprains. Half of injuries were to the hand/wrist/digits and 13% were to the back. Of the penetrating wounds, 87% were to the hand/wrist/digits, 32% became infected, and 80% were caused by contact with finfish, shellfish, or other marine animal. Of the strains/sprains, 48% were to the back and 26% were to the shoulder. Seventy percent of strains/sprains were caused by moving heavy objects, mainly either while hauling in nets, pots, or lines or loading/unloading the boat. Conclusion: In this group of small scale, independent fishers, the most common reported injuries were penetrating wounds to the hand/wrist/digits from marine animals and strains/sprains to the back while moving heavy objects.

The aim of this article was to explore retrospectively the Takei dynamometer as a valid and reliable outcome measure tool for hand and wrist pathology in the Great Britain amateur boxing squad between 2010 and 2014. Longitudinal retrospective injury surveillance of the Great Britain boxing squad was performed from 2010 to 2014. The location, region affected, description, and duration of each injury were recorded by the team doctor and team physiotherapists. For each significant injury, we recorded hand grip scores using the Takei handheld dynamometer and compared the scores with baseline measures. At the hand, fractures and dislocations were highly detected with an average difference of 40.2% ( P < .05) when comparing postinjury to baseline measures. At the wrist, carpometacarpal and carpal joint injuries were highly detected with an average difference of 32.6% ( P < .05). Other injuries provided varied results. In the absence of pathology, up to 15% difference between left and right scores can be considered normal with a predominance observed below 10%. A difference of 20% can be indicative of a form of pathology, although pathologies can also be present with lower difference or no apparent changes. A difference of >20% should be highly considered for significant pathology. The Takei dynamometer is a valid and reliable outcome measure tool for hand and wrist pathologies in boxing. Our study highlights the importance of appropriate clinical tools to guide injury management in this sport.

A large proportion of spinal cord injuries (SCI) are incomplete. Even in clinically complete injuries, silent non-functional connections can be present. Therapeutic approaches that can strengthen transmission in weak neural connections to improve motor performance are needed. Our aim was to determine whether long-term delivery of paired associative stimulation (PAS, a combination of transcranial magnetic stimulation [TMS] with peripheral nerve stimulation [PNS]) can enhance motor output in the hands of patients with chronic traumatic tetraplegia, and to compare this technique with long-term PNS. Five patients (4 males; age 38-68, mean 48) with no contraindications to TMS received 4 weeks (16 sessions) of stimulation. PAS was given to one hand and PNS combined with sham TMS to the other hand. Patients were blinded to the treatment. Hands were selected randomly. The patients were evaluated by a physiotherapist blinded to the treatment. The follow-up period was 1 month. Patients were evaluated with Daniels and Worthingham's Muscle Testing (0-5 scale) before the first stimulation session, after the last stimulation session, and 1 month after the last stimulation session. One month after the last stimulation session, the improvement in the PAS-treated hand was 1.02 ± 0.17 points (p < 0.0001, n = 100 muscles from 5 patients). The improvement was significantly higher in PAS-treated than in PNS-treated hands (176 ± 29%, p = 0.046, n = 5 patients). Long-term PAS might be an effective tool for improving motor performance in incomplete chronic SCI patients. Further studies on PAS in larger patient cohorts, with longer stimulation duration and at earlier stages after the injury, are warranted.

Clinical Assessment and Diagnostics of Patients With Hand Disorders: A Case Study Approach.

Leow, Mabel Qi He; Lim, Rebecca Qian Ru; Tay, Shian Chao

Clinical assessment of the hand is important for diagnosing underlying hand disorders. Using a case study approach, the clinical assessment for three disorders of the hands is presented: trigger finger (stenosing tenosynovitis), carpal tunnel syndrome, and ulnar-sided wrist injury (styloid impingement). We assess the annular one pulley and finger range of motion for patients with trigger finger. To diagnose for carpal tunnel syndrome, assessment for Tinel's sign, Phalen's sign, abductor pollicis brevis muscle bulk, two-point discrimination, and obtaining a nerve conduction study are performed. Assessment for ulnar-sided wrist injury includes wrist range of motion, assessment of distal radial ulnar joint stability, provocation tests, grip strength, x-ray, and magnetic resonance imaging. This article begins with a description of the hand and wrist anatomy. For each case study, the clinical history is described, followed by a discussion of the pathophysiology, clinical assessments, and diagnostic tests.

2018-06-01

This study conducted two series of experiments to investigate the relationships between hand coupling force and biodynamic responses of the hand-arm system. In the first experiment, the vibration transmissibility on the system was measured as a continuous function of grip force while the hand was subjected to discrete sinusoidal excitations. In the second experiment, the biodynamic responses of the system subjected to a broadband random vibration were measured under five levels of grip forces and a combination of grip and push forces. This study found that the transmissibility at each given frequency increased with the increase in the grip force before reaching a maximum level. The transmissibility then tended to plateau or decrease when the grip force was further increased. This threshold force increased with an increase in the vibration frequency. These relationships remained the same for both types of vibrations. The implications of the experimental results are discussed. Practitioner Summary: Shocks and vibrations transmitted to the hand-arm system may cause injuries and disorders of the system. How to take hand coupling force into account in the risk assessment of vibration exposure remains an important issue for further studies. This study is designed and conducted to help resolve this issue.

Kendo is a Japanese martial art analogous to fencing, which is becoming increasingly popular worldwide. The large number of participants creates a need to assess injury patterns to better train them. The purpose of this study is to describe current injury rates in kendo and compare these rates to other martial arts. This retrospective study used an online questionnaire sent to 500 active members of the All United States Kendo Federation and World Kendo Federation. The questionnaire, based on the NCAA Injury Surveillance System, contains questions regarding location and type of injuries sustained during competition and practice, time lost to training, and competitor demographics. Statistical analyses between competitor demographics and injury rates are provided. Injury rates are expressed as injury rates/minute of competition or practice and by athlete exposures. 95% CIs were calculated. Responses from 307 of 500 kendo players were received (response rate = 61.4%). 41 (18%) male and 13 (16%) female participants reported injury to only one body region, while 16 (7%) men and one (1%) woman reported no injuries. 166 (74%) males and 70 (83%) females reported injuries to two or more body regions. The most common sites of injury involved the foot/ankle (65.1%), wrist/hand (53.5%) and elbow/forearm (48.8%). Most injuries occurred during practice (87.9% foot/ankle, 89.9% wrist/hand, elbow/forearm 92.2%). The most common injuries were contusions, abrasions, and sprains/strains. Injury rates were 121/1000 A-E (0.025 injuries/min) in tournaments versus 20.5/1000 A-E (0.011 injuries/min) in training. 26% of injuries resulted in time off of participation, with an average recovery time of 15 days (range = 1 day-1 year). Although more total injuries occurred in practice than in competition, there was a lower injury rate in kendo than in taekwondo and western-style fencing. This study demonstrates that kendo is a relatively safe sport compared to other martial arts sports.

Human hands play a significant role during Extravehicular Activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. Because of this high frequency usage, hand and arm related injuries are known to occur during EVA and EVA training in the NBL. The primary objectives of this investigation were to: 1) document all known EVA glove related injuries and circumstances of these incidents, 2) determine likely risk factors, and 3) recommend interventions where possible that could be implemented in the current and future glove designs. METHODS: The investigation focused on the discomforts and injuries of U.S. crewmembers who had worn the pressurized Extravehicular Mobility Unit (EMU) spacesuit and experienced 4000 Series or Phase VI glove related incidents during 1981 to 2010 for either EVA ground training or in-orbit flight. We conducted an observational retrospective case-control investigation using 1) a literature review of known injuries, 2) data mining of crew injury, glove sizing, and hand anthropometry databases, 3) descriptive statistical analyses, and finally 4) statistical risk correlation and predictor analyses to better understand injury prevalence and potential causation. Specific predictor statistical analyses included use of principal component analyses (PCA), multiple logistic regression, and survival analyses (Cox proportional hazards regression). Results of these analyses were computed risk variables in the forms of odds ratios (likelihood of an injury occurring given the magnitude of a risk variable) and hazard ratios (likelihood of time to injury occurrence). Due to the exploratory nature of this investigation, we selected predictor variables significant at p=0.15. RESULTS: Through 2010, there have been a total of 330 NASA crewmembers, from which 96 crewmembers performed 322 EVAs during 1981-2010, resulting in 50 crewmembers being injured inflight and 44

To survey the American Society for Surgery of the Hand membership to determine the nature and distribution of nerve injuries treated after elbow arthroscopy. An online survey was sent to all members of the American Society for Surgery of the Hand under an institutional review board-approved protocol. Collected data included the number of nerve injuries observed over a 5-year period, the nature of treatment required for the injuries, and the outcomes observed after any intervention. Responses were anonymous, and results were securely compiled. We obtained 372 responses. A total of 222 nerve injuries were reported. The most injured nerves reported were ulnar, radial, and posterior interosseous (38%, 22%, and 19%, respectively). Nearly half of all patients with injuries required operative intervention, including nerve graft, tendon transfer, nerve repair, or nerve transfer. Of the patients who sustained major injuries, those requiring intervention, 77% had partial or no motor recovery. All minor injuries resolved completely. Our results suggest that major nerve injuries after elbow arthroscopy are not rare occurrences and the risk of these injuries is likely under-reported in the literature. Furthermore, patients should be counseled on this risk because most nerve injuries show only partial or no functional recovery. With the more widespread practice of elbow arthroscopy, understanding the nature and sequelae of significant complications is critically important in ensuring patient safety and improving outcomes.

Treadmills: a preventable source of pediatric friction burn injuries.

PubMed

Maguiña, Pirko; Palmieri, Tina L; Greenhalgh, David G

2004-01-01

Treadmills are a burn risk for children. A child's hand can get trapped in the conveyor belt, causing friction burns to the underlying tissue. The purpose of this retrospective study was to review the characteristics and treatment of treadmill-related burns in children from 1998 to 2002. Ten patients, at a mean age of 3.4 years, sustained injuries associated with treadmill use. Trapping of the hand between the conveyor belt and the base was the most frequent injury mechanism. Burn location was predominantly on fingers and palms. Four patients required operative intervention. All patients required specialized wound care as well as scar management and occupational therapy. Treadmills pose a danger to children. Current safety devices are ineffective for preventing serious hand injuries in children. New design modifications and public awareness are needed to improve child safety.

Scar Management of the Burned Hand

Unimpaired hand function is critical in almost all activities of daily living. Burn injury can result in hypertrophic scar formation that can lead to debilitating functional deficits and poor aesthetic outcomes. Initial algorithms of acute burn management involve early debridement and skin grafting and early mobilization to prevent formation of hypertrophic scarring and ultimately digit contractures. While non-operative modalities in the early phase of scar maturation are critical to minimize hypertrophic scar formation, surgical management is often indicated in order to restore hand function. The essential tenant of operative scar management is release of tension, which can often be achieved through local tissue rearrangement. Laser therapy has emerged as a central pillar of subsequent scar rehabilitation with several modalities that address scar texture, color, pruritis and thickness. These can be utilized in conjunction with local corticosteroid treatment and other emerging modalities to modulate the scar and achieve optimal hand function. These treatment tools provide an effective resource for the reconstructive surgeon to treat hypertrophic hand scars. PMID:28363297

Several cases are described in which severe radiation injuries occurred in the hands of surgeons during operative procedures requiring fluoroscopy. The radiation lesions appeared to be aggravated by the various mechanical traumas accompanying washing-up processes preceding surgery including brushing the fingers, use of strong disinfectants and detergents, and sprinkling the hands with talcum before donning rubber gloves. These routine measures may cause acute eruptions of old radiation lesions. Various phases in the development of radiation burns on the hands, from the initial dermatitis to the late necrotic changes, are discussed. Fraquently, the early lesions are erroneously diagnosed as allergic eczemamore » so that effective therapeutic measures may not be instituted soon enough. Plastic surgical rapairs of finger lesions, in the cases described, are illustrated. (H.H.D.)« less

Background Paralysis of the upper-limbs from spinal cord injury results in an enormous loss of independence in an individual’s daily life. Meaningful improvement in hand function is rare after one year of tetraparesis. Therapeutic developments that result in even modest gains in hand volitional function will significantly impact the quality of life for patients afflicted with high cervical injury. The ability to neuromodulate the lumbosacral spinal circuitry via epidural stimulation in regaining postural function and volitional control of the legs has been recently shown. A key question is whether a similar neuromodulatory strategy can be used to improve volitional motor control of the upper-limbs, i.e., performance of motor tasks considered to be less “automatic” than posture and locomotion. In this study, the effects of cervical epidural stimulation on hand function are characterized in subjects with chronic cervical cord injury. Objective Herein we show that epidural stimulation can be applied to the chronic injured human cervical spinal cord to promote volitional hand function. Methods and results Two subjects implanted with an cervical epidural electrode array demonstrated improved hand strength (approximately three-fold) and volitional hand control in the presence of epidural stimulation. Conclusions The present data are sufficient to suggest that hand motor function in individuals with chronic tetraplegia can be improved with cervical cord neuromodulation and thus should be comprehensively explored as a possible clinical intervention.

Caine, Dennis J; Nassar, Larry

2005-01-01

The purpose of this chapter is to review the distribution and determinants of injury rates as reported in the pediatric gymnastics injury literature, and to suggest measures for the prevention of injury and directions for further research. An extensive search of Pubmed was conducted using the Text and MeSH words "gymnastics" and "injury" and limited to the pediatric population (0-18 years). The review focused on studies using denominator-based designs and on those published in the English language. Additional references were obtained from hand searches of the reference lists. Unpublished injury data from the USA Gymnastics National Women's Artistic Gymnastics Championships during 2002-04 were also analyzed. Comparison of study results was compromised due to the diversity of study populations, variability of injury definition across studies, and changes in rules and equipment across years. Notwithstanding, this review of the literature reveals a reasonably consistent picture of pediatric gymnastics injuries. The incidence and severity of injuries is relatively high, particularly among advanced level female gymnasts. Body parts particularly affected by injury vary by gender and include the ankle, knee, wrist, elbow, lower back, and shoulder. Ankle sprains are a particular concern. Overuse and nonspecific pain conditions, particularly the wrist and low back, occur frequently among advanced-level female gymnasts. Factors associated with an increased injury risk among female gymnasts include greater body size and body fat, periods of rapid growth, and increased life stress. Above all, this overview of the gymnastics injury literature underscores the need to establish large-scale injury surveillance systems designed to provide current and reliable data on injury trends in both boys and girls gymnastics, and to be used as a basis for analyzing injury risk factors and identifying dependable injury preventive measures.

American flag football is a non-tackle, contact sport with many moderate to severe contact-type injuries reported. A previous prospective injury surveillance study by the authors revealed a high incidence of injuries to the fingers, face, knee, shoulder and ankle. The objectives of the study were to conduct a pilot-prospective injury prevention study in an attempt to significantly reduce the incidence and the severity of injuries as compared to a historical cohort, as well as to provide recommendations for a future prospective injury prevention study. A prospective injury prevention study was conducted involving 724 amateur male (mean age: 20.0 ± 3.1 years) and 114 female (mean age: 21.2 ± 7.2 years) players. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. An injury surveillance questionnaire was administered to record all time-loss injuries sustained in game sessions. There was a statistically significant reduction in the number of injured players, the number of finger/hand injuries, the incidence rate and the incidence proportion between the two cohorts (p < 0.05). This one-season pilot prevention study has provided preliminary evidence that finger/hand injuries can be significantly reduced in flag football. Prevention strategies for a longer, prospective, randomised-controlled injury prevention study should include the strict enforcement of the no-pocket rule, appropriate head gear, the use of comfortable-fitting ankle braces and mouth guards, and changing the blocking rules of the game.

Patient-Reported Outcome Measures for Hand and Wrist Trauma: Is There Sufficient Evidence of Reliability, Validity, and Responsiveness?

Dacombe, Peter Jonathan; Amirfeyz, Rouin; Davis, Tim

2016-03-01

Patient-reported outcome measures (PROMs) are important tools for assessing outcomes following injuries to the hand and wrist. Many commonly used PROMs have no evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. This systematic review examines the PROMs used in the assessment of hand and wrist trauma patients, and the evidence for reliability, validity, and responsiveness of each measure in this population. A systematic review of Pubmed, Medline, and CINAHL searching for randomized controlled trials of patients with traumatic injuries to the hand and wrist was carried out to identify the PROMs. For each identified PROM, evidence of reliability, validity, and responsiveness was identified using a further systematic review of the Pubmed, Medline, CINAHL, and reverse citation trail audit procedure. The PROM used most often was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Patient-Rated Wrist Evaluation (PRWE), Gartland and Werley score, Michigan Hand Outcomes score, Mayo Wrist Score, and Short Form 36 were also commonly used. Only the DASH and PRWE have evidence of reliability, validity, and responsiveness in patients with traumatic injuries to the hand and wrist; other measures either have incomplete evidence or evidence gathered in a nontraumatic population. The DASH and PRWE both have evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. Other PROMs used to assess hand and wrist trauma patients do not. This should be considered when selecting a PROM for patients with traumatic hand and wrist pathology.

Systematic reviews are fundamental decision-making tools for the assessment of the effectiveness of healthcare interventions and for determining future research fields. In the field of hand surgery, so far, there exists only a limited number of systematic reviews. According to the diversity and multitude of hand surgical topics, relevant fields for systematic reviews were identified by means of an expert ranking. A catalogue of 24 topics was extracted from publications of representative hand surgical journals. These topics were categorized and integrated into a questionnaire which was presented to 30 experts in the field of hand surgery. Every single topic had to be rated by marks from 1 (very relevant) to 5 (not relevant). Further topics could have been indicated. Averaging of the marks allowed to define a ranking and a prioritisation of the topics. 29 of 30 questionnaires were returned. The ranking showed scapholunate ligament injury, Kienboeck's disease and scaphoid nonunion to have the highest relevance, followed by 5 other topics dealing with wrist problems. The lowest relevance was attributed to neck fractures of the fifth metacarpal, ulnar collateral ligament injury of the thumb metacarpophalangeal joint and postoperative management following replantation. The results of the presented survey allow for a prioritisation of topics for systematic reviews in hand surgery. The ranking of the topics emphasises the particular relevance of injuries and diseases of the wrist. © Georg Thieme Verlag KG Stuttgart · New York.

Wheelbarrow tire explosion causing trauma to the forearm and hand: a case report

PubMed Central

2009-01-01

Introduction Tire explosion injuries are rare, but they may result in a severe injury pattern. Case reports and statistics from injuries caused by exploded truck tires during servicing are established, but trauma from exploded small tires seems to be unknown. Case presentation A 47-year-old german man inflated a wheelbarrow tire. The tire exploded during inflation and caused an open, multiple forearm and hand injury. Conclusion Even small tires can cause severe injury patterns in the case of an explosion. High inflating pressures and low safety distances are the main factors responsible for this occurrence. Broad safety information and suitable filling devices are indispensable for preventing these occurrences. PMID:19946543

Analysis of karate injuries sustained in 295 contests.

1976-11-01

The injuries sustained in 295 karate contests were analysed. It was noted that in 25 per cent of the contests there was some sort of injury, and in 10 per cent the injury was severe enough to cause the withdrawal of the participant. Injury seemed to occur most commonly among lower-grade participants and more often in the first hour of each day's competition. Protective padding of the arms, legs, feet and hands, and the use of gumshields and protective boxes appeared to reduce the incidence and severity of injury.

Democratic Republic of Congo (DRC), a particular form of juvenile delinquency and insecurity intensifies in the city of Kinshasa. This is the phenomenon Kuluna. It is organized gangs equipped with machetes and other weapons. The main objective of this study is to know the phenomenon Kuluna and describe the upper limb injuries caused by machetes, while insisting on the specifics of the management of these lesions in our communities. This retrospective descriptive study examines 14 cases of wounds of the hand and forearm due to stab phenomenon Kuluna, in Kinshasa. It covers the period from 1 November 2010 to 1 November 2013. Among the 14 patients with lesions in the hand and forearm admitted and treated at the Unit of Plastic Reconstructive and Aesthetic Surgery, Hand Surgery and Burns, University Clinics of Kinshasa to attacks due to the phenomenon Kuluna. We have 11 men and 3 women. The average age was 33, 5 years (extremes of 21 and 56 years). The right upper limb is reached that the left upper limb, respectively 12 patients and 2 patients. The lesions are localized to the wrist in the majority of cases (10 patients) in the palm of hand and in 3 patients in the fingers in 1 patient. The palmar surface is reached (10 cases) and the dorsal (4 cases). Zone 5 of the International Classification of flexor and Zone 8 topographic classification extensors at hand are the predilection sites of lesions respectively the palmar surface (6 out of 10) and the dorsal (2 case 4). The median nerve at the wrist is cut in half the cases. On bone lesions localized to the forearm, we observed a high incidence of fracture of the ulna (62.5%). The treatment begins with the stabilization of bone pieces, gestures revascularization and nerve sutures and suture tendon and finally skin coverage. Rehabilitation was mandatory, she supervises the actions of repair and it continues until the recovery of function.

Ligamentous and capsular injuries to the metacarpophalangeal joints of the hand.

Shah, Smiresh Suresh; Techy, Fernando; Mejia, Alfonso; Gonzalez, Mark H

2012-01-01

The mechanism of dorsal dislocation of the metacarpophalangeal (MCP) joint is with forced hyperextension of the joint and the main structure injured is the volar plate. A simple dislocation can be reduced by closed means whereas a complex dislocation cannot. Care must be taken not to put traction across the joint, which may cause the volar plate to slip into the joint, converting a simple dislocation into a complex dislocation. Volar dislocations are rare and mainly treated nonoperatively. Sagittal band injuries can be treated with extension splinting or surgical management with direct repair or reconstruction. A locked MCP joint can usually be treated with closed manipulation. This article discusses these injuries and management options.

Hand surgery fellowship programs in the United States are predominately sponsored by departments or divisions of orthopaedic surgery or plastic surgery. This study compares the operative experiences of hand surgery fellows graduating from orthopaedic or plastic surgery hand surgery fellowships. Operative case logs of 3 cohorts of hand surgery fellows graduating during the academic years of 2012-2013, 2013-2014, and 2014-2015 were analyzed. The median case volumes were compared by specialty via Mann-Whitney U tests. An arbitrary 1,000% change between the 90th and 10th percentiles of fellows was used as a threshold to highlight case categories with substantial variability. In this study, 413 orthopaedic hand surgery fellows (87%) and 62 plastic surgery hand surgery fellows (13%) were included. Plastic surgery fellows reported more cases in the following categories: wound closure with graft; wound reconstruction with flap; vascular repair, reconstruction, replantation, or microvascular; closed treatment of fracture or dislocation; nerve injury; and congenital (p < 0.05). Orthopaedic surgery fellows reported more cases in the following categories: wound irrigation and debridement fasciotomy or wound preparation; hand reconstruction or releases; wrist reconstruction, releases, or arthrodesis; forearm, elbow, or shoulder reconstruction or releases; hand fractures, dislocation, or ligament injury; wrist fractures or dislocations; forearm and proximal fractures or dislocations; miscellaneous insertion or removal of devices; shoulder arthroscopy, elbow arthroscopy, and wrist arthroscopy; decompression of tendon sheath, synovectomy, or ganglions; nerve decompression; Dupuytren; and tumor or osteomyelitis (p < 0.05). Plastic surgery fellows reported substantial variability for 12 case categories (range, 1,024% to 2,880%). Orthopaedic surgery fellows reported substantial variability for 9 case categories (range, 1,110% to 9,700%). Orthopaedic and plastic hand surgery

To report the epidemiology, mechanism, anatomical location, distribution, and severity of open extensor tendon injuries in the digits, hand, and forearm as well as the frequency of associated injuries to surrounding bone and soft tissue. Retrospective chart review was conducted for patients who had operative repair of open digital extensor tendon injuries in all zones within an 11-year period. Data was grouped according to patient characteristics, zone of injury, mechanism of injury, and presence of associated injury. Statistical analysis was used to determine the presence of relevant associations. Eighty-six patients with 125 severed tendons and 105 injured digits were available for chart reviews. Patients were predominantly males (83%) with a mean age of 34.2 years and the dominant extremity was most often injured (60%). The thumb was the most commonly injured (25.7%), followed by middle finger (24.8), whereas small finger was least affected (10.5%). Sharp laceration was the most common mechanism of injury (60%), and most of these occurred at or proximal to the metacarpophalangeal joints. Most saw injuries occurred distal to the metacarpophalangeal joint. Zone V was the most commonly affected in the fingers (27%) while zone VT was the most commonly affected in the thumb (69%). Associated injuries to bone and soft tissue occurred in 46.7% of all injuries with saw and crush/avulsions being predictive of fractures and damage to the underlying joint capsule. The extensor mechanism is anatomically complex, and open injuries to the dorsum of the hand, wrist, and forearm, especially of crushing nature and those inflicted by saws, must be thoroughly evaluated. Associated injuries should be ruled out in order to customize surgical treatment and optimize outcome.

Computer vision-based classification of hand grip variations in neurorehabilitation.

Zariffa, José; Steeves, John D

2011-01-01

The complexity of hand function is such that most existing upper limb rehabilitation robotic devices use only simplified hand interfaces. This is in contrast to the importance of the hand in regaining function after neurological injury. Computer vision technology has been used to identify hand posture in the field of Human Computer Interaction, but this approach has not been translated to the rehabilitation context. We describe a computer vision-based classifier that can be used to discriminate rehabilitation-relevant hand postures, and could be integrated into a virtual reality-based upper limb rehabilitation system. The proposed system was tested on a set of video recordings from able-bodied individuals performing cylindrical grasps, lateral key grips, and tip-to-tip pinches. The overall classification success rate was 91.2%, and was above 98% for 6 out of the 10 subjects. © 2011 IEEE

Injury rates in Shotokan karate

OBJECTIVE: To document the injury rate in three British Shotokan karate championships in consecutive years. In these tournaments strict rules governed contact, with only "light" or "touch" contact allowed. Protective padding for the head, hands, or feet was prohibited. METHODS: Prospective recording of injuries resulting from 1770 bouts in three national competitions of 1996, 1997, and 1998. Details of ages and years of karate experience were also obtained. RESULTS: 160 injuries were sustained in 1770 bouts. The overall rate of injury was 0.09 per bout and 0.13 per competitor. 91 (57%) injuries were to the head. The average age of those injured was 22 years, with an average of nine years of experience in karate. CONCLUSIONS: The absence of protective padding does not result in higher injury rates than in most other series of Shotokan karate injuries. Strict refereeing is essential, however, to maintain control and minimise contact.

Nowadays, the increasing old population 65+ as well as the pace imposed by work activities lead to a high number of people that have particular injuries for limbs. In addition to persistent or temporary disabilities related to accidental injuries we must take into account that part of the population suffers from motor deficits of the hands due to stroke or diseases of various clinical nature. The most recurrent technological solutions to measure the rehabilitation or skill motor performance of the hand are glove-based devices, able to faithfully capture the movements of the hand and fingers. This paper presents a system for hand motion analysis based on 9-axis complete inertial modules and dedicated microcontroller which are fixed on fingers and forearm. The technological solution presented is able to track the patients' hand motions in real-time and then to send data through wireless communication reducing the clutter and the disadvantages of a glove equipped with sensors through a different technological structure. The device proposed has been tested in the study of Parkinson's disease.

Recovery of nerve injury-induced alexia for Braille using forearm anaesthesia.

Björkman, Anders; Rosén, Birgitta; Lundborg, Göran

2008-04-16

Nerve injuries in the upper extremity may severely affect hand function. Cutaneous forearm anaesthesia has been shown to improve hand sensation in nerve-injured patients. A blind man who lost his Braille reading capability after an axillary plexus injury was treated with temporary cutaneous forearm anaesthesia. After treatment sensory functions of the hand improved and the patient regained his Braille reading capability. The mechanism behind the improvement is likely unmasking of inhibited or silent neurons, but after repeated treatment sessions at increasing intervals the improvement has remained at 1-year follow-up, implying a structural change in the somatosensory cortex.

2017-07-01

The aim of this study was to examine the effect of the side of brain lesion on the ipsilesional hand function of stroke survivors. Twenty-four chronic stroke survivors, equally allocated in 2 groups according to the side of brain lesion (right or left), and 12 sex- and age-matched healthy controls performed the Jebsen-Taylor Hand Function Test (JTHFT), the Nine-Hole Peg Test (9HPT), the maximum power grip strength (PwGS max ) test, and the maximum pinch grip strength (PnGS max ) test. Only the ipsilesional hand of the stroke survivors and both hands (left and right) of the controls were assessed. PwGS max and PnGS max were similar among all tested groups. Performances in JTHFT and 9HPT were affected by the brain injury. Individuals with left brain damage showed better performance in 9HPT than individuals with right brain damage, but performance in JTHFT was similar. Individuals after a brain injury have the capacity to produce maximum strength preserved when using their ipsilesional hand. However, the dexterity of their hands and digits is affected, in particular for stroke individuals with right brain lesion. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

Work-Related Musculoskeletal Disorders of the Hand and Wrist: Epidemiology, Pathophysiology, and Sensorimotor Changes

PubMed Central

Barr, Ann E.; Barbe, Mary F.; Clark, Brian D.

2006-01-01

The purpose of this commentary is to present recent epidemiological findings regarding work-related musculoskeletal disorders (WMSDs) of the hand and wrist, and to summarize experimental evidence of underlying tissue pathophysiology and sensorimotor changes in WMSDs. Sixty-five percent of the 333 800 newly reported cases of occupational illness in 2001 were attributed to repeated trauma. WMSDs of the hand and wrist are associated with the longest absences from work and are, therefore, associated with greater lost productivity and wages than those of other anatomical regions. Selected epidemiological studies of hand/wrist WMSDs published since 1998 are reviewed and summarized. Results from selected animal studies concerning underlying tissue pathophysiology in response to repetitive movement or tissue loading are reviewed and summarized. To the extent possible, corroborating evidence in human studies for various tissue pathomechanisms suggested in animal models is presented. Repetitive, hand-intensive movements, alone or in combination with other physical, nonphysical, and nonoccupational risk factors, contribute to the development of hand/wrist WMSDs. Possible pathophysiological mechanisms of tissue injury include inflammation followed by repair and/or fibrotic scarring, peripheral nerve injury, and central nervous system reorganization. Clinicians should consider all of these pathomechanisms when examining and treating patients with hand/wrist WMSDs. PMID:15552707

Fishing injuries commonly affect the hands. The goal of this study was to quantify the incidence of fishing-related upper extremity injuries that present to emergency departments in the United States. We examined the reported cases of fishing-related upper extremity injuries in the National Electronic Injury Surveillance System database. Analysis was performed based on age, sex and the type of injury reported. The national incidence of fishing-related upper extremity injuries was 119.6 per 1 million person-years in 2014. The most common anatomic site for injury was the finger (63.3%), followed by the hand (20.3%). The most common type of injury in the upper extremity was the presence of a foreign body (70.4%). The incidence of fishing-related upper extremity injuries in males was 200 per 1 million person-years, which was significantly higher than the incidence in females (41 per 1 million person-years). The incidence of fishing-related upper extremity injuries that present to the Emergency Department was 120 per 1 million person-years. The incidence was significantly higher in males. With the widespread popularity of the activity, it is important for Emergency Physicians and Hand Surgeons to understand how to properly evaluate and manage these injuries.

Tendon and ligament injuries: the genetic component

PubMed Central

September, Alison V; Schwellnus, Martin P; Collins, Malcolm

2007-01-01

Tendons and ligaments within the upper and lower limbs are some of the more common sites of musculoskeletal injuries during physical activity. Several extrinsic and intrinsic factors have been shown to be associated with these injuries. More recently, studies have suggested that there is also, at least in part, a genetic component to the Achilles tendon, rotator cuff and anterior cruciate ligament injuries. However, specific genes have not been suggested to be associated with rotator cuff or anterior cruciate ligament injuries. Sequence variants of the tenascin C (TNC) gene, on the other hand, have been shown to be associated with Achilles tendinopathies and Achilles tendon ruptures, whereas a variant of the collagen V α 1 (COL5A1) gene has also been shown to be associated with Achilles tendinopathies. Both genes encode for important structural components of tendons and ligaments. The COL5A1 gene encodes for a component of type V collagen, which has an important role in regulating collagen fibre assembly and fibre diameters. The TNC gene, on the other hand, encodes for TNC, which regulates the tissue's response to mechanical load. To date, only variants in two genes have been shown to be associated with Achilles tendon injuries. In addition, although specific genes have not been identified, investigators have suggested that there is also a genetic component to both rotator cuff and anterior cruciate ligament injuries. In future, specific genotypes associated with increased risk of injury to specific tendons and ligaments can prevent these injuries by identifying individuals at higher risk. PMID:17261551

The apparent mass and mechanical impedance of the hand and the transmission of vibration to the fingers, hand, and arm

NASA Astrophysics Data System (ADS)

Concettoni, Enrico; Griffin, Michael

2009-08-01

Although hand-transmitted vibration causes injury and disease, most often evident in the fingers, the biodynamic responses of the fingers, hand, and arm are not yet well understood. A method of investigating the motion of the entire finger-hand-arm system, based on the simultaneous measurement of the biodynamic response at the driving point and the transmissibility to many points on the finger-hand-arm system, is illustrated. Fourteen male subjects participated in an experiment in which they pushed down on a vertically vibrating metal plate with their right forearm pronated and their elbow bent at 90°. The apparent mass and mechanical impedance of the finger-hand-arm system were measured for each of seven different contact conditions between the plate and the fingers and hand. Simultaneously, the vibration of the fingers, hand, and arm was measured at 41 locations using a scanning laser Doppler vibrometer. Transmissibilities showed how the vibration was transmitted along the arm and allowed the construction of spectral operating deflection shapes showing the vibration pattern of the fingers, hand, and arm for each of the seven contact conditions. The vibration patterns at critical frequencies for each contact condition have been used to explain features in the driving point biodynamic responses and the vibration behaviour of the hand-arm system. Spectral operating deflection shapes for the upper limb assist the interpretation of driving point biodynamic responses and help to advance understanding required to predict, explain, and control the various effects of hand-transmitted vibration.

Heelys and street gliders injuries: a new type of pediatric injury.

2007-06-01

Our goals were to highlight an increasing trend in orthopedic injuries in children as a result of "heeling" or "street gliding," to describe injuries sustained by children using Heelys (HSL, Carrollton, TX) and Street Gliders (Glowgadgets Ltd, Bristol, United Kingdom), and to increase public awareness and prevent such injuries. We prospectively recorded the data of all roller shoes injuries referred to our department during the summer school holiday. Using a data-collection sheet, we recorded demographic data, type of injury, mechanism and place of injury, heeling or street-gliding experience, use of safety equipment, methods of treatment, and intention to continue heeling or street gliding after recovery from injury. Over a 10-week period, 67 children suffered orthopedic injuries while using Heelys or Street Gliders. There were 56 girls and 11 boys with a mean age of 9.6 years. Upper limbs were the most common location of injury. Distal radius fractures were the most prevalent, followed by supracondylar fractures, elbow dislocations, and hand fractures. The majority of children suffered the injury while heeling or street gliding outdoors. Interestingly, 20% of the injuries happened while trying Heelys or Street Gliders for the first time, and 36% of the injuries occurred while learning (using 1-5 times) how to use them. None of the children used any sort of protective gear at the time of the injury. The majority of the injured children expressed their intention to continue heeling or street gliding after complete recovery from their injury. Our study shows that the majority of children with injuries from heeling or street gliding are girls. We recommend close supervision of children using Heelys or Street Gliders during the steep learning curve and usage of protective gear at all times. These new types of injuries have a serious impact on child health and constitute a burden for the pediatric orthopedic service.

This study compared didactic hand surgery training during orthopedic and plastic surgery residency. The Plastic Surgery In-Service Training Exam and Orthopaedic In-Training Examination were analyzed for hand content for the years 2009 to 2013. Topics were categorized with the content outline for the Surgery of the Hand Examination. Differences were elucidated by means of Fisher's exact test. Relative to the Orthopaedic In-Training Examination, the Plastic Surgery In-Service Training Exam had greater hand representation (20.3 percent versus 8.1 percent; p < 0.001) with more annual hand questions (40 ± 3 versus 24 ± 2; p < 0.001). The Plastic Surgery Exam questions had more words, were less often level I-recall type, and were less often image-based. The questions focused more on finger and hand/palm anatomy, whereas the Orthopaedic examination was more wrist-focused. The Plastic Surgery Exam emphasized wound management and muscle/tendon injuries, but underemphasized fractures/dislocations. References differed, but Journal of Hand Surgery (American Volume) and Green's Operative Hand Surgery were common on both examinations. The Plastic Surgery Exam had a greater publication lag for journal references (10.7 ± 0.5 years versus 9.0 ± 0.6; p = 0.035). Differences in didactic hand surgery training are elucidated for plastic surgery and orthopedic residents. Deficiencies in the Plastic Surgery In-Service Training Exam hand curriculum relative to the Orthopaedic In-Training Examination may underprepare plastic surgeons for the Surgery of the Hand Examination. These data may assist future modifications to hand surgery training in the United States.

We evaluated demographic and occupational features of patients with phalangeal fractures of the hand, etiologies and types of injuries, and the results of rehabilitation. The study included 91 fingers of 62 patients (54 males, 8 females; mean age 28+/-13 years; range 4 to 59 years) who were referred to our hand rehabilitation unit for phalangeal fractures. Demographic features, the cause and localization of injury, the type of surgery, time from surgery to rehabilitation, and the follow-up period were determined. At the end of rehabilitation, range of motion (ROM) of the phalangeal joint and total ROM of the injured fingers were assessed using the Strickland-Glogovac rating system. A great majority of injuries were caused by work accidents, followed by sport injuries and falls occurring in students. Sixty patients (96.8%) were right-handed. The fractures occurred in the dominant hand in 29 patients (46.8%). The majority of patients (n=45) were primary school graduates. The most common mechanism of injury was accidents related to heavy work machinery (n=18). The most commonly injured finger and the phalanx were the third finger (n=25, 27.5%) and the proximal phalanx (n=59, 56.7%), respectively. Only 27 patients (43.6%) had a sufficient follow-up with a mean of 79.7+/-46.6 days (range 30 to 254 days). Following rehabilitation, the mean ROM and the total ROM were 45.0+/-22.9 degrees and 63.3+/-16.1 degrees for the injured joint and the thumb, and 31.3+/-22.5 degrees and 122+/-60.3 degrees for the injured joint and the other fingers, respectively. Our data provide important insight into appropriate treatment and rehabilitation of phalangeal fractures, in particular, shortcomings in the treatment and follow-up.

The aim of the work has been to evaluate the risk of injuries connected to the use of machinery and work tools in the footwear industry. The analysis of the data related to injuries in the footwear industry, deduced from the registers of injuries collected in the investigated factories, shows that most accidents arise from the contact of the operator's hands with tools and machinery parts during their use. Risk factors generally include the inherent specific danger of some work tools and machines, the lack or inadequacy of safety devices, the obsolescence of the equipment, the imprudence and underestimation of risk.

To describe circumstances surrounding injuries involving nail guns among carpenters, calculate injury rates, identify high risk groups and preventive measures. and setting: Active injury surveillance was used to identify causes of injury among a large cohort of union residential and drywall carpenters. Injured carpenters were interviewed by experienced journeymen; enumeration of workers and hourworked were provided by the union. The combined data allowed definition of a cohort of carpenters, their hours worked, detailed information on the circumstances surrounding injuries, and identification of preventive measures from the perspectives of the injured worker and an experienced investigator. Nail guns were involved in 14% of injuries investigated. Ninety percent of these injuries were the result of the carpenter being struck, most commonly by a nail puncturing a hand or fingers. The injury rate among apprentices was 3.7 per 200 000 hours worked (95% confidence interval (CI) 2.7 to 4.9) compared with a rate of 1.2 among journeymen (95% CI 0.80 to 1.7). While not always the sole contributing factor, a sequential trigger would have likely prevented 65% of the injuries from tools with contact trip triggers. Training, engineering, and policy changes in the workplace and manufacturing arena are all appropriate targets for prevention of these injuries. Use of sequential triggers would likely decrease acute injury rates markedly. Over 70% of injuries among residential carpenters were associated with through nailing tasks (such as nailing studs or blocks, trusses or joists) or toe nailing (angled, corner nailing) as opposed to flat nailing used for sheathing activities; this provides some indication that contact trip tools could be used solely for flat nailing.

2010-01-01

To patients who have lost the functionality of their hands as a result of a severe spinal cord injury or brain stroke, the development of new techniques for grasping is indispensable for reintegration and independency in daily life. Functional Electrical Stimulation (FES) of residual muscles can reproduce the most dominant grasping tasks and can be initialized by brain signals. However, due to the very complex hand anatomy and current limitations in FES-technology with surface electrodes, these grasp patterns cannot be smoothly executed. In this paper, we present an adaptable passive hand orthosis which is capable of producing natural and smooth movements when coupled with FES. It evenly synchronizes the grasping movements and applied forces on all fingers, allowing for naturalistic gestures and functional grasps of everyday objects. The orthosis is also equipped with a lock, which allows it to remain in the desired position without the need for long-term stimulation. Furthermore, we quantify improvements offered by the orthosis compare them with natural grasps on healthy subjects.

Abstract In this cross-sectional study, we surveyed all pediatric orthopedic surgeons in Saudi Arabia using an anonymous electronic questionnaire composed of 23 items to identify the rate of occupational injuries and obtain other relevant information. Thirty-nine participants completed the questionnaire (response rate: 83%). Participants who sustained occupational injuries throughout their careers represented 82.5%. The most injured areas were the hands, eyes, and back by 54.5%, 24.2%, and 15.2%, respectively. Approximately 11.1% were injured while operating on infected patients. Approximately 30.3% reported their injuries to their institution. We concluded that the rate of occupational injuries among pediatric orthopedic surgeons is very high and underreported.

Open fractures of the hand are a common and varied group of injuries. Although at increased risk for infection, open fractures of the hand are more resistant to infection than other open fractures. Numerous unique factors in the hand may play a role in the altered risk of postinjury infection. Current systems for the classification of open fractures fail to address the unique qualities of the hand. This article proposes a novel classification system for open fractures of the hand, taking into account the factors unique to the hand that affect its risk for developing infection after an open fracture.

Effects of vibration appear as mechanical and psychological disorders, including stress reactions, cognitive and movement disorders, problem in concentration and paying attention to the assigned duties. The common signs and symptoms of hand-arm vibration (HAV) in the fingers and hands may appear as pins and needles feeling, tingling, numbness, and also the loss of finger sensation and dexterity. Laboratory Virtual Instrument Engineering Workbench programming software designed for occupational vibrations measurement was used to calculate HAV acceleration. Hole steadiness test is designed to measure involuntary movement of people. V-Pieron test is designed for one of the other aspects of the psycho motor phenomena of steadiness by moving the stylus across a V-form ruler. The two points test was an experiment of touch acuity, which used a caliper by placing the two styli very close on the pad of finger knuckles. The temperature of finger skin is also measured simultaneous to the above tests. Wilcoxon test indicated that a significant decrement in hand steadiness occurred after gripping a vibrating handle for 2 min (P ≤ 0.003). Wilcoxon test also represented a significant change in errors after gripping a grinder vibratory handle (P ≤ 0.003). The differences at all of the knuckles were significant with a confidence interval percentage of 99%. There was a significant reduction in finger skin temperature before and after exposure to vibration (mean = 0.45°C, based on paired sample test). The obtained results considerably demonstrated the relation between hand performance and vibrations due to gripping a grinder. It can be concluded that an injury or accident may happen after exposure to vibrations for the fine duties, in fast actions. PMID:29204383

Mountain biking injuries in children and adolescents.

PubMed

Aleman, Kylee B; Meyers, Michael C

2010-01-01

Over the last decade, the sport of mountain biking has experienced extensive growth in youth participation. Due to the unpredictable nature of outdoor sport, a lack of rider awareness and increased participation, the number of injuries has unnecessarily increased. Many believe that the actual incidence of trauma in this sport is underestimated and is just the 'tip of the iceberg'. The most common mechanism of injury is usually attributed to downhill riding and forward falling. Although rare, this type of fall can result in serious cranial and thoraco-abdominal trauma. Head and neck trauma continue to be documented, often resulting in concussions and the possibility of permanent neurological sequelae. Upper limb injuries range from minor dermal abrasions, contusions and muscular strains to complex particular fracture dislocations. These are caused by attempting to arrest the face with an outstretched hand, leading to additional direct injury. Common overuse injuries include repeated compression from the handlebars and vibration leading to neurovascular complications in the hands. Along with reports of blunt abdominal trauma and lumbar muscle strains, lower extremity injuries may include various hip/pelvic/groin contusions, patellofemoral inflammation, and various muscle strains. The primary causes of mountain biking injuries in children and adolescents include overuse, excessive fatigue, age, level of experience, and inappropriate or improperly adjusted equipment. Additional factors contributing to trauma among this age group involve musculoskeletal immaturity, collisions and falls, excessive speed, environmental conditions, conditioning and fitness status of the rider, nonconservative behavioural patterns, and inadequate medical care. The limited available data restrict the identification and understanding of specific paediatric mountain biking injuries and injury mechanisms.

High-voltage electrical injury has been well documented in a number of situations, such as the occupational hazard of linesmen and construction workers, and in the context of overhead railway power lines. Two cases of hang-glider pilots contacting 11,000-volt power lines have recently been treated in the Royal Brisbane Hospital Burns Unit. They demonstrate an interesting pattern of injury, not described in current burns literature, involving both hand and lower abdominal burns. Both patients sustained full-thickness patches of burn injury, with underlying muscle damage and peripheral neurological injury. This distribution of injury seems to be closely related to the design of the hang glider.

We studied the epidemiology of paediatric firework-related injury in the urban population of Delhi during the festival of lights (Diwali). In this prospective observational study, data were collected on the day of Diwali for two consecutive years, 2010 and 2011. All children with firework injuries coming to the emergency room were included in the study. Data were recorded in a predesigned proforma. Of the 65 cases, 75% were males and 25% were females; most children were more than 10 years of age and majority (90%) of them were unsupervised. Half (49%) of the cases were due to misuse of the fireworks or erratic behaviour, among which the most common observed mode was igniting cracker while holding it (18 cases; 24% of total injuries), which led to injuries to the hand and palm. Device failure was the next common cause for firework injuries, including unexpected blast of the crackers and string bomb as the most common. Overall, the most commonly injured body sites were hands (62%), face (32%) and eyes (10%). Crackers and string bomb mainly caused injuries to hands; fountains and gunpowder caused injuries to the face. Sixty (94%) children were managed conservatively and 5 (6%) required skin grafting and tendon repair. We recommend parental supervision especially for males, wearing non-synthetic and non-flowing clothes, promoting branded crackers and educational campaigns in schools to curtail the rising trend in firework-related injuries in the paediatric population. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Alexander Scriabin: his chronic right-hand pain and Its impact on his piano compositions.

PubMed

Altenmüller, Eckart

2015-01-01

Alexander Scriabin was an outstanding pianist and an avant-garde composer who influenced later generations with his innovative "multimedia" conceptions of aesthetic experience. As an adolescent, he was systematically trained as a concert pianist and received lessons from Vassily Safonoff, one of the founders of the legendary Russian Piano School. At age 20, Scriabin suffered an overuse injury of his right hand when attempting to improve the sound quality of his piano touch. This injury caused a deep crisis and influenced his later composition style in his piano works. From this time on, his works were frequently dominated by unusual virtuosic use and wide spans of his left hand. Rest, restricted repertoire, and an increased focus on composition contributed to recovery; however, he always remained anxious concerning the stamina of his right hand. The case report impressively demonstrates the stressors an aspiring young pianist had to cope with at the end of the nineteenth century. Furthermore, it is a convincing example of how resource-oriented behavior and intuition lead to the improvement of health status. Differential diagnoses and the modern concept of multimodal pain therapy in chronic overuse injury will be discussed from a historical perspective. © 2015 Elsevier B.V. All rights reserved.

Intravenous (IV) administration of iodinated contrast agents (ICAs) is frequently employed for image enhancement while performing radiographic studies such as computed tomography and angiography. Complications related to IV administration of ICAs such as immediate hypersensitivity reactions and nephrotoxicity are well-known. However, severe skin and soft tissue injuries and acute compartment syndrome resulting from contrast extravasation are rare. This is especially so with small volume extravasation of a low osmolar, nonionic ICA such as iohexol. Here, we report a 63-year-old woman who developed acute compartment syndrome of left hand following iohexol extravasation and had swelling, blistering, cutaneous and soft tissue necrosis. She underwent fasciotomy for acute compartment syndrome of hand and later surgical debridement of necrotic skin and soft tissues was carried out. Clinical pharmacology of ICAs, extravasation injuries following their IV administration, their management and measures to reduce them are discussed in brief. PMID:27127398

2014-01-01

Scalpels are utilized by many different user groups for such purposes as medical procedures and dissection. Injuries caused by scalpels are a potential risk for scalpel users, and include injuries that may occur while mounting and removing the scalpel blade. Between 10% and 20% of all scalpel injuries in education and healthcare settings are reported to occur while scalpel blades are being mounted or removed. At present there are few published or "best practice" demonstrations of safe technique for scalpel blade mounting and removal. This brief article outlines a variation of the procedure for scalpel blade mounting and removal. It includes strategies developed to minimize risk or injury for the scalpel user, including providing a stable base for the hands and arms so as to prevent unnecessary large amplitude movements that may lead to injury of the scalpel user or a third party. Such a technique may promote scalpel safety, contribute to the development of "best practice" scalpel use, and help decrease injuries that may be caused while mounting or removing scalpel blades. © 2013 American Association of Anatomists.

Groin Flap in Paediatric Age Group to Salvage Hand after Electric Contact Burn: Challenges and Experience

Introduction Electric contact burn is characterised by multiple wounds produced by entrance and exit of the current. Hand is most commonly involved in the same and children are particularly susceptible to such accidents. Aim To document effectiveness and challenges associated with the use of groin flap as an initial definitive treatment of electric contact burn in paediatric age group. Materials and Methods From January 2015 to December 2016, 25 children up to 12 years of age, who were admitted at SMS Medical College, Jaipur, Rajasthan, India, after electric burn injury with hand defect and who were treated by pedicled groin flap at the Department of Plastic and Reconstructive Surgery, were included in the study. Details related to gender, age, type of voltage injury, sites of injury and postoperative complications were recorded. The groin flap was used in these children for coverage of hand and finger defect with exposed bone and tendon. Results Normal functional results were seen in all children treated with pedicled groin flap and all were able to perform activities of daily living. All the children had satisfactory aesthetic result. Conclusion Although, groin flap was an uncomfortable procedure due to limb position that was particularly difficult for children, it was found to be a useful method to salvage hand and it resulted in favourable functional and aesthetic outcome in each case.

This original prospective cohort study was conducted in an attempt to significantly reduce the incidence and the severity of injuries in an intervention cohort as compared to a two-season historical cohort, and to provide recommendations to the International Federation of Football (IFAF) pertaining to prevention measures to make the game safer. A total of 1,260 amateur male (mean age: 20.4 ± 3.9 years) and 244 female (mean age: 18.5 ± 1.7 years) players participated in the study. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. All time-loss injuries sustained in game sessions were recorded by the off-the-field medical personnel and followed up by a more detailed phone injury surveillance questionnaire. There was a 54 % reduction in the total number of injuries and a significant reduction in the incidence rate and incidence proportion between the intervention cohorts as compared to the historical cohort (p < 0.001). There was no statistically significant reduction in the number of injuries in any of the body parts, except for in hand/wrist injuries related to the use of pockets (p < 0.001), as well as the severity of mild-moderate injuries (p < 0.05). This study provided evidence that hand/wrist injuries can be significantly reduced in flag football. Recommendations to the IFAF include strict enforcement of the no-pocket rule, the use of soft headgear, comfortable-fitting ankle braces and mouth guards and additionally, to change game rules concerning blocking.

Treadmill injuries in young children are a serious but little documented problem. Friction burns occur when the hands come into contact with the moving belt resulting in deep burns that often require hospital admission and surgery. The aim of this study was to assess the nature and prevalence of injuries sustained and to highlight treadmill friction burns as a public health issue previously undocumented in Ireland. A retrospective chart review from January 2006 until March 2008 was performed and functional outcome was assessed by the modified Michigan Hand Outcomes Questionnaire. Eight girls and four boys from one year and seven months to seven years and five months were treated. Eight children required admission to hospital and to date three have required surgery for their injuries. This is a new and increasing problem in Ireland which must be highlighted.

Specialization of the left supramarginal gyrus for hand-independent praxis representation is not related to hand dominance.

Króliczak, Gregory; Piper, Brian J; Frey, Scott H

2016-12-01

Data from focal brain injury and functional neuroimaging studies implicate a distributed network of parieto-fronto-temporal areas in the human left cerebral hemisphere as playing distinct roles in the representation of meaningful actions (praxis). Because these data come primarily from right-handed individuals, the relationship between left cerebral specialization for praxis representation and hand dominance remains unclear. We used functional magnetic resonance imaging (fMRI) to evaluate the hypothesis that strongly left-handed (right hemisphere motor dominant) adults also exhibit this left cerebral specialization. Participants planned familiar actions for subsequent performance with the left or right hand in response to transitive (e.g., "pounding") or intransitive (e.g. "waving") action words. In linguistic control trials, cues denoted non-physical actions (e.g., "believing"). Action planning was associated with significant, exclusively left-lateralized and extensive increases of activity in the supramarginal gyrus (SMg), and more focal modulations in the left caudal middle temporal gyrus (cMTg). This activity was hand- and gesture-independent, i.e., unaffected by the hand involved in subsequent action performance, and the type of gesture (i.e., transitive or intransitive). Compared directly with right-handers, left-handers exhibited greater involvement of the right angular gyrus (ANg) and dorsal premotor cortex (dPMC), which is indicative of a less asymmetric functional architecture for praxis representation. We therefore conclude that the organization of mechanisms involved in planning familiar actions is influenced by one's motor dominance. However, independent of hand dominance, the left SMg and cMTg are specialized for ideomotor transformations-the integration of conceptual knowledge and motor representations into meaningful actions. These findings support the view that higher-order praxis representation and lower-level motor dominance rely on dissociable

Epidemiology, results of treatment, impact on activity of daily living (ADL), and costs for treatment of digital nerve injuries have not been considered consistently. Case notes of patients of 0-99 years of age living in Malmö municipality, Sweden, who presented with a digital nerve injury and were referred to the Department of Hand Surgery in 1995-2005 were analysed retrospectively. The incidence was 6.2/100 000 inhabitants and year. Most commonly men (75%; median age 29 years) were injured. Isolated nerve injuries and concomitant tendon injuries were equally common. The direct costs (hospital stay, operation, outpatient visits, visits to a nurse and/or a hand therapist) for a concomitant tendon injury was almost double compared with an isolated digital nerve injury (6136 EUR [range, 744-29 689 EUR] vs 2653 EUR [range, 468-6949 EUR]). More than 50% of the patients who worked were injured at work and 79% lost time from work (median 59 days [range 3-337]). Permanent nerve dysfunction for the individual patient with ADL problems and subjective complaints of fumbleness, cold sensitivity, and pain occur in the patients despite surgery. It is concluded that digital nerve injuries, often considered as a minor injury and that affect young people at productive age, cause costs, and disability. Focus should be directed against prevention of the injury and to improve nerve regeneration from different aspects.

Every doctor can be confronted, during his career, with patients presenting symptoms they created themselves. Because it is easily accessible, the hand is a favored target organ for these self-inflicted injuries. The diagnosis of factitious disorder of the hand is very difficult, rarely suggested and widely under-estimated. The real issue is detecting it early on to develop a cohesive diagnostic and therapeutic approach. The three clinical cases reported in this article illustrate the difficulty of caring for this pathology at all stages, from diagnosis to treatment. These disorders must be distinguished from malingering. A psychiatrist must be part of the treatment team. The prognosis of factitious disorders is poor. It is vital to maintain contact with the patient once the diagnosis is established. The risk is that the patient consults with other professionals, restarting a new cycle. The featured clinical cases were chosen to remind surgeons that factitious disorders of the hand are a recognized psychiatric disease. It must be evoked in the context of an unusual injury with a vague history. Everything possible must be done to confirm the diagnosis and avoid surgery. Copyright © 2018 SFCM.

With the incidence of work-related injuries decreasing, we continue to observe an unchanged trend in leisure-related accidents. As in any other hobby, model flying devices bear the risk for accidents among builders and flyers ranging from skin lacerations to complicated and even life-threatening injuries. The fast-moving razor-sharp propeller blades predominantly cause trauma to the hands and fingers resulting in typical multiple parallel skin injuries also affecting structures deep to the dermis (e. g., tendons, vessels and nerves). The resultant clinical management involves complex reconstructive surgical procedures and prolonged rehabilitative follow-up. Improving the legal framework (e. g., warnings by the manufacturer) on the one hand, providing informative action and sensitising those affected on the other, should form a basis for an altered prevention strategy to reduce model flying device-related injuries in the future. © Georg Thieme Verlag KG Stuttgart · New York.

Use of tissue adhesive as a field expedient barrier dressing for hand wounds in disaster responders.

PubMed

Levy, Matthew J; Tang, Nelson

2014-02-01

Injuries sustained by disaster responders can impede the affected individuals' ability to perform critical functions and often require the redirection of already scarce resources. Soft-tissue injuries to the hand are commonly experienced by disaster workers and even seemingly mild lacerations can pose the potential for significant complications in such hazard-filled environments. In this report, the authors describe their experience utilizing tissue adhesive to create a functional and effective barrier dressing for a hand injury sustained by a responder at the West, Texas USA fertilizer plant explosion. This technique of wound management allowed the patient to continue performing essential onsite functions for a sustained period following the explosion and the subsequent investigative processes. At the 30-day follow-up, the wound was well healed and without complications. This technique proved to be a valuable method of field expedient wound management and is worthy of consideration in similar future circumstances.

Effectiveness of functional hand splinting and the cognitive orientation to occupational performance (CO-OP) approach in children with cerebral palsy and brain injury: two randomised controlled trial protocols

PubMed Central

2014-01-01

Background Cerebral palsy (CP) and brain injury (BI) are common conditions that have devastating effects on a child’s ability to use their hands. Hand splinting and task-specific training are two interventions that are often used to address deficits in upper limb skills, both in isolation or concurrently. The aim of this paper is to describe the method to be used to conduct two randomised controlled trials (RCT) investigating (a) the immediate effect of functional hand splints, and (b) the effect of functional hand splints used concurrently with task-specific training compared to functional hand splints alone, and to task-specific training alone in children with CP and BI. The Cognitive Orientation to Occupational Performance (CO-OP) approach will be the task-specific training approach used. Methods/Design Two concurrent trials; a two group, parallel design, RCT with a sample size of 30 participants (15 per group); and a three group, parallel design, assessor blinded, RCT with a sample size of 45 participants (15 per group). Inclusion criteria: age 4-15 years; diagnosis of CP or BI; Manual Abilities Classification System (MACS) level I – IV; hand function goals; impaired hand function; the cognitive, language and behavioural ability to participate in CO-OP. Participants will be randomly allocated to one of 3 groups; (1) functional hand splint only (n=15); (2) functional hand splint combined with task-specific training (n=15); (3) task-specific training only (n=15). Allocation concealment will be achieved using sequentially numbered, sealed opaque envelopes opened by an off-site officer after baseline measures. Treatment will be provided for a period of 2 weeks, with outcome measures taken at baseline, 1 hour after randomisation, 2 weeks and 10 weeks. The functional hand splint will be a wrist cock-up splint (+/- thumb support or supination strap). Task-specific training will involve 10 sessions of CO-OP provided in a group of 2-4 children.

Fortington, Lauren V; Donaldson, Alex; Finch, Caroline F

2016-01-01

Background Increasing participation by women in Australian football (AF) has made understanding their specific injury prevention needs a priority. In other sports, men and women have different injury profiles. This study aims to provide the first overview of self-reported injuries in women's AF. Methods Nationwide survey of women aged 17+ years who played in an AF competition was conducted following the 2014 playing season. The players' self-reported worst injury from the 2014 season is presented according to injury type, body part injured, treatment sought and games/training missed. Results Three-quarters of 553 respondents (n=431, 78%) reported at least 1 injury. Over half (n=235, 55%) of injuries were to the lower limb. Ankle ligament tears/sprains (n=50, 12% of all injuries) and knee ligament tears/sprains (n=45, 10%) were most frequent lower limb injuries reported. Two-thirds (65%) of all lower limb injuries led to at least 1 missed game. Of 111 (26% of all injuries) upper limb injuries reported, over half (n=57, 62%) were to the hand/fingers/thumb, including fractures (n=28, 6% of all injuries), ligament tears/sprains (n=18, 4%) and dislocations (n=11, 3%). Half of the upper limb injuries (51%) resulted in players missing matches/training. Conclusions The most frequent self-reported worst injuries for women playing AF were joint damage to the ankle and knee. A prospective injury study is needed to confirm the causes and rate of these lower limb injuries to identify the most suitable prevention interventions. PMID:27900178

The Influence of Speed and Grade on Wheelchair Propulsion Hand Pattern

Slowik, Jonathan S.; Requejo, Philip S.; Mulroy, Sara J.; Neptune, Richard R.

2015-01-01

Background The hand pattern used during manual wheelchair propulsion (i.e., full-cycle hand path) can provide insight into an individual's propulsion technique. However, previous analyses of hand patterns have been limited by their focus on a single propulsion condition and reliance on subjective qualitative characterization methods. The purpose of this study was to develop a set of objective quantitative parameters to characterize hand patterns and determine the influence of propulsion speed and grade of incline on the patterns preferred by manual wheelchair users. Methods Kinematic and kinetic data were collected from 170 experienced manual wheelchair users on an ergometer during three conditions: level propulsion at their self-selected speed, level propulsion at their fastest comfortable speed, and graded propulsion (8%) at their level self-selected speed. Hand patterns were quantified using a set of objective parameters and differences across conditions were identified. Findings Increased propulsion speed resulted in a shift away from under-rim hand patterns. Increased grade of incline resulted in the hand remaining near the handrim throughout the cycle. Interpretation Manual wheelchair users change their hand pattern based on task-specific constraints and goals. Further work is needed to investigate how differences between hand patterns influence upper extremity demand and potentially lead to the development of overuse injuries and pain. PMID:26228706

The purpose of this systematic review was to evaluate the effectiveness of exercise compared to other interventions, placebo/sham intervention, or no intervention in improving self-rated recovery, functional recovery, clinical, and/or administrative outcomes in individuals with musculoskeletal disorders and injuries of the elbow, forearm, wrist, and hand. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials from 1990 to 2015. Paired reviewers independently screened studies for relevance and assessed the risk of bias using the Scottish Intercollegiate Guidelines Network criteria. We synthesized the evidence using the best evidence synthesis methodology. We identified 5 studies with a low risk of bias. Our review suggests that, for patients with persistent lateral epicondylitis, (1) adding concentric or eccentric strengthening exercises to home stretching exercises provides no additional benefits; (2) a home program of either eccentric or concentric strengthening exercises leads to similar outcomes; (3) home wrist extensor strengthening exercises lead to greater short-term improvements in pain reduction compared to "wait and see"; and (4) clinic-based, supervised exercise may be more beneficial than home exercises with minimal improvements in pain and function. For hand pain of variable duration, supervised progressive strength training added to advice to continue normal physical activity provides no additional benefits. The relative effectiveness of stretching vs strengthening for the wrist extensors remains unknown for the management of persistent lateral epicondylitis. The current evidence shows that the addition of supervised progressive strength training does not provide further benefits over advice to continue normal physical activity for hand pain of variable duration.

Pain-related psychological issues in hand therapy.

PubMed

Hamasaki, Tokiko; Pelletier, René; Bourbonnais, Daniel; Harris, Patrick; Choinière, Manon

Literature review. Pain is a subjective experience that results from the modulation of nociception conveyed to the brain via the nervous system. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats of injury. This appraisal is influenced by one's cognitions and emotions based on her/his pain-related experiences, which are processed in the forebrain and limbic areas of the brain. Unarguably, patients' psychological factors such as cognitions (eg, pain catastrophizing), emotions (eg, depression), and pain-related behaviors (eg, avoidance) can influence perceived pain intensity, disability, and treatment outcomes. Therefore, hand therapists should address the patient pain experience using a biopsychosocial approach. However, in hand therapy, a biomedical perspective predominates in pain management by focusing solely on tissue healing. This review aims to raise awareness among hand therapists of the impact of pain-related psychological factors. This literature review allowed to describe (1) how the neurophysiological mechanisms of pain can be influenced by various psychological factors, (2) several evidence-based interventions that can be integrated into hand therapy to address these psychological issues, and (3) some approaches of psychotherapy for patients with maladaptive pain experiences. Restoration of sensory and motor functions as well as alleviating pain is at the core of hand therapy. Numerous psychological factors including patients' beliefs, cognitions, and emotions alter their pain experience and may impact on their outcomes. Decoding the biopsychosocial components of the patients' pain is thus essential for hand therapists. Copyright © 2018 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

PubMed

Freixes, Orestes; Fernandez, Sergio Anibal; Gatti, Marcelo Andres; Crespo, Marcos Jose; Olmos, Lisandro Emilio; Russo, Maria Julieta

2017-01-01

Background: Subjects with spinal cord injury (SCI) propel their wheelchairs by generating a different level of muscle activity given their multiple deficits in muscle strength. Exercise training programs seem to be effective in improving wheelchair propulsion capacity. Functional electrical stimulation (FES) therapy is a complementary tool for rehabilitation programs. Objectives : To determine the accuracy of the synchronization between the FES activation and the push phase of the propulsion cycle by using hand pressure sensors that allow anterior deltoids activation when the hand is in contact with the pushrim. Methods: We analyzed 2 subjects, with injuries at C6 American Spinal Injury Association Impairment Scale (AIS) A and T12 AIS A. The stimulation parameters were set for a 30 Hz frequency symmetrical biphasic wave, 300 μs pulse width. Data were collected as participants propelled the wheelchair over a 10-m section of smooth, level vinyl floor. Subjects were evaluated in a motion analysis laboratory (ELITE; BTS, Milan, Italy). Results: Subject 1 showed synchronization between the FES activation and the push phase of 87.5% in the left hand and of 80% in the right hand. Subject 2 showed synchronization of 95.1% in the left and of hand 94.9% in the right hand. Conclusion : Our study determined a high accuracy of a novel FES therapeutic option, showing the synchronization between the electrical stimulation and the push phase of the propulsion cycle.

Fingertip injuries with nail bed trauma can require specialist hand surgery, depending on severity. However, most of these injuries can be managed in well-equipped emergency departments by emergency nurses with an in-depth knowledge and understanding of the anatomy and physiology of the fingernail and surrounding structures, assessment and examination, pain management and treatment. This article describes the surface and underlying anatomy and physiology of the nail, the most common mechanisms of injury, relevant diagnostic investigations, and initial assessment and management. It also discusses treatment options, referral pathways, and patient discharge advice.

Andersen, T; Arnason, A; Engebretsen, L; Bahr, R

2004-01-01

Objectives: The aim of this study was to describe, using video analysis, the mechanisms of head injuries and of incidents with a high risk of head injury in elite football. Methods: Videotapes and injury information were collected prospectively for 313 of the 409 matches played in the Norwegian (2000 season) and Icelandic (1999 and 2000 season) professional leagues. Video recordings of incidents where a player appeared to be hit in the head and the match was consequently interrupted by the referee were analysed and cross referenced with reports of acute time loss injuries from the team medical staff. Results: The video analysis revealed 192 incidents (18.8 per 1000 player hours). Of the 297 acute injuries reported, 17 (6%) were head injuries, which corresponds to an incidence of 1.7 per 1000 player hours (concussion incidence 0.5 per 1000 player hours). The most common playing action was a heading duel with 112 cases (58%). The body part that hit the injured player's head was the elbow/arm/hand in 79 cases (41%), the head in 62 cases (32%), and the foot in 25 cases (13%). In 67 of the elbow/arm/hand impacts, the upper arm of the player causing the incident was at or above shoulder level, and the arm use was considered to be active in 61 incidents (77%) and intentional in 16 incidents (20%). Conclusions: This study suggests that video analysis provides detailed information about the mechanisms for head injuries in football. The most frequent injury mechanism was elbow to head contact, followed by head to head contact in heading duels. In the majority of the elbow to head incidents, the elbow was used actively at or above shoulder level, and stricter rule enforcement or even changes in the laws of the game concerning elbow use should perhaps be considered, in order to reduce the risk of head injury.

The American Medical Association (AMA) and National Institutes of Health (NIH) recommend that patient education materials be written at no higher than a sixth-grade reading level. We examined 100 online educational materials for the 10 hand conditions most commonly treated by hand surgeons, as reported by the American Society for Surgery of the Hand. The listed conditions were carpal tunnel syndrome, basal joint arthritis of the thumb, de Quervain syndrome, Dupuytren's contracture, ganglion cysts, hand fractures, trigger finger, extensor tendon injuries, flexor tendon injuries, and mallet finger. Following a Google search for each condition, we analyzed the 10 most visited websites for each disorder utilizing the Flesch-Kincaid formula. The average grade reading level of the 100 websites studied was 9.49 with a reading ease of 53.03 ("fairly difficult high school"). Only 29% of the websites were at or below the national average of an eighth-grade reading level. Carpal tunnel syndrome had the highest average grade reading level at 10.32 (standard deviation: 1.52), whereas hand fractures had the lowest at 8.14 (2.03). Every hand condition in this study had an average readability at or above the ninth-grade reading level. The most frequently accessed materials for common maladies of the hand exceed both the readability limits recommended by the AMA and NIH, and the average reading ability of most US adults. Therefore, the most commonly accessed websites pertaining to hand pathology may not be comprehended by the audience for which it is intended.

Orthopedic fractures are a common injury in operational activities, injuries that often occur in isolated or hostile environments. Clinical ultrasound devices have become more user friendly and lighter allowing them to be easily transported with forward medical teams. The bone-soft tissue interface has a very large acoustic impedance, with a high reflectance that can be used to visualize breaks in contour including fractures. Herein reported is a case of an ulnar fracture that was quickly visualized in the early phase of a multi-system trauma resuscitation with a hand-held ultrasound device. The implications for operational medicine are discussed.

Ratfish (Chimaera) spine injuries in fishermen.

PubMed

Hayes, A J; Sim, A J W

2011-08-01

An occupational hazard peculiar to fishermen, is an injury from a sharp fish spine. Such spines can cause envenomation injury, infectious sequelae or trauma to anatomical structures. The management of two fishermen with penetrating ratfish (Chimaera) spine injuries to the lower limb is described. Both were managed by removal of the spine under general anaesthesia. In the second patient, the spine was embedded adjacent to the left femoral artery, highlighting the potential for major haemorrhage and supporting the use of surgical wound exploration when important structures may be involved. Herein, we describe the first report in English of Chimaera spine injury. In addition, we surveyed nine northeast Atlantic deep-sea fishermen to gain information on exposure to, and injuries from, this type of fish. The most commonly identified species was Chimaera monstrosa. Five fishermen reported injuries to their feet or hands from Chimaera spines and two had sought medical attention. The evidence indicates that deep-sea trawler fishermen of the northeast Atlantic frequently encounter Chimaera species and can suffer dangerous penetrating wounds from its dorsal spine.

Particularly challenging after complete brachial plexus avulsion is reestablishing effective hand function, due to limited neurological donors to reanimate the arm. Acute repair of avulsion injuries may enable reinnervation strategies for achieving hand function. This patient presented with pan-brachial plexus injury. Given its irreparable nature, the authors recommended multistage reconstruction, including contralateral C-7 transfer for hand function, multiple intercostal nerves for shoulder/triceps function, shoulder fusion, and spinal accessory nerve-to-musculocutaneous nerve transfer for elbow flexion. The video demonstrates distal contraction from electrical stimulation of the avulsed roots. Single neurorrhaphy of the contralateral C-7 transfer was performed along with a retrosternocleidomastoid approach. The video can be found here: https://youtu.be/GMPfno8sK0U .

2017-09-01

Background  Fractures or fracture dislocations of the proximal interphalangeal joint often occur during sports or accidents. Dislocations of the PIP-joint are the most common ligamentary injuries of the hand. As this kind of injury is so frequent, hand surgeons and other physicians should be aware of the correct treatment. Objectives  This paper summarises the most common injury patterns and the correct treatment of PIP-joint dislocations. Materials and Methods  This paper reviews the current literature and describes the standardised treatment of PIP-joint dislocations. Results  What is most important is that reposition is anatomically correct, and this should be controlled by X-ray examination. Depending on the instability and possible combination with other injuries (e. g. injury to the palmar plate), early functional physiotherapy of the joint or a short immobilisation period is indicated. Conclusions  Early functional treatment of the injured PIP-joint, initially using buddy taping, is important to restore PIP-joint movement and function. Depending on the injury, joint immobilisation using a K-wire may be indicated. Detailed informed consent is necessary to explain to the patient the severity of the injury and possible complications, such as chronic functional disorders or development of arthrosis. © Georg Thieme Verlag KG Stuttgart · New York.

Preventable wheelchair-related thermal injury.

Bull, William; Priebe, Michael; Dillig, Gina; Dado, Diane

2006-01-01

Wheelchair-related injuries are common, and with proper reporting of injuries, advanced technologic support may offer new ways to prevent those injuries. Case REPORT AND FINDINGS: A man with tetraplegia who retains only minimal use of his right hand experienced a right-sided armrest malfunction of his wheelchair resulting in his wheelchair controls being out of reach. This left him stranded in the sun for almost 2 hours in 86 degrees F weather. During that time, he developed full thickness sunburns of his left forearm and deep partial thickness burns of the left fingertips where they were in contact with the left armrest. This patient's full thickness burns could have been prevented if his motorized wheelchair had back-up communication in the event of a malfunction. Technology developers must realize the need for such systems. Health care professionals must advocate for a higher standard of safety and report injuries related to wheelchair malfunction.

Sallam, Asser A; El-Deeb, Mohamed S; Imam, Mohamed A

2017-04-01

To assess the efficacy of nerve transfer versus nerve grafting in restoring motor and sensory hand function in patients with complete, isolated high ulnar nerve injuries. A retrospective chart review was performed, at a minimum 2 years of follow-up, of 52 patients suffering complete, isolated high ulnar nerve injury between January 2006 and June 2013 in one specialized hand surgery unit. Twenty-four patients underwent motor and sensory nerve transfers (NT group). Twenty-eight patients underwent sural nerve grafting (NG group). Motor recovery, return of sensibility and complications were examined as outcome measures. The Medical Research Council scale was applied to evaluate sensory and motor recovery. Grip and pinch strengths of the hand were measured. Twenty of 24 patients (83.33%) in the NT group regained M3 grade or greater for the adductor pollicis, the abductor digiti minimi, and the medial 2 lumbricals and interossei, compared with only 16 of 28 patients (57.14%) in the NG group. Means for percentage recovery of grip strengths compared with the other healthy hand were significantly higher for the NT group than the NG group. Sensory recovery of S3 or greater was achieved in more than half of each group with no significant difference between groups. Nerve transfer is favored over nerve grafting in managing high ulnar nerve injuries because of better improvement of motor power and better restoration of grip functions of the hand. Therapeutic IV.

2015-03-01

Skin features have been employed by law enforcement agencies for suspect and victim identification. Comparisons of hand have arisen in casework where images have been submitted where a face was not present but a hand was visible. This research utilizes a collection of 128 hands from employees of the U.S. Army Criminal Investigation Laboratory to examine the frequency and distribution of skin detail on the dorsal surface of the hand. To assess the location of features, the hand was segmented into 14 regions using readily discernible anatomical landmarks. Overall, 2618 pigmented lesions and 92 scars or injuries were documented. When comparing the regions with one another, Regions 1-10 had fewer pigmented lesions than Regions 11-14. There was no pattern to the distribution of scars throughout the regions. The findings presented a foundation for one possible method that may differentiate hands based on the frequency and distribution of such features. Published 2014.

The first step in infection control is hand hygiene.

PubMed

Canham, Leslie

2011-01-01

A dental health care worker (DHCW) has an obligation to prevent the spread of health care associated infections. Adhering to proper hand hygiene procedures, selecting appropriate hand hygiene products and the use of gloves are all important elements of infection control. The CDC Guidelines for Hand Hygiene state that improved hand hygiene practices can reduce transmission of pathogenic microorganisms to patients and personnel in health care settings. DHCWs must also protect themselves by recognizing pitfalls such as irritants or allergies that may pose obstacles to proper hand hygiene. Occupational irritants and allergies can be caused by frequent hand washing, exposure to hand hygiene products, exposure to chemicals and shear forces associated with wearing or removing gloves. Since the primary defense against infection and transmission of pathogens is healthy, unbroken skin, DHCWs must take steps to ensure that their skin remains healthy and intact. These steps include evaluating different types of hand hygiene products, lotions and gloves for the best compatibility. If the DHCW sees a breakdown of his or her skin barrier, steps should be taken to determine the cause and remedy. Remedies can include the use of alcohol-based hand sanitizers containing emollients and moisturizers and regular use of a medical grade hand lotion. The bottom line: healthy skin protects you at work and at home. Selection and use of appropriate hand hygiene products, including moisturizers, are an essential part ofa dental office infection control program. My coworker lost the use of her thumb for several months due to complications of a staph infection. She was unable to work and found even simple tasks such as closing a button hard to do. Think of how difficult your work would be if something happened to your hands. Injury, irritation or allergies could alter your ability to work or even perform routine tasks.

2014-04-01

Homer's Iliad--the most famous and influential epic poem--has been previously reviewed with respect to head, craniomaxillofacial, neck, thoracic, and hand injuries in the literature. However, to the best of the authors' knowledge, there are no data regarding musculoskeletal injuries. This article describes the musculoskeletal injuries that had ensued during the war of Troy. The Turkish translation of the original epic poem Iliad was reviewed for musculoskeletal injuries, that is, their descriptions, outcome, the weapons used, and the engaged warriors. Extremity injuries were evaluated as regards the affected bones. The pertinent treatment methods were also recorded. In total, 103 musculoskeletal injuries were detected during 81 combats. The most commonly involved areas were the shoulder (15.5%), the head (14.5%), the cervical vertebrae (14.5%), and the thoracic vertebrae (8.7%). The weapons used were spear (n = 52); sword (n = 9); arrow (n = 9); stone (n = 8); and cane, animal, the hand, Chariot race, and broken yoke (n = 1 for each). Fifty-four combats (66.6%) resulted in death. Therapeutic herbs, compound of milk, and essence of fig were used as treatment alternatives. While providing a historic snapshot on the war of Troy, in this article, the authors have reviewed the musculoskeletal injuries and their management in those ancient times. Despite the long period in between, unfortunately, physicians/surgeons are still faced with war injuries in current medical practice. The authors strongly hope that, at least in the near future, physicians will be left with only natural health problems and without those artificially generated by human beings.

Work-related injuries are commonly seen in the emergency department (ED). This study sought to analyze characteristics of ED patient visits that were billed under workers' compensation. This was a retrospective chart review of visits during 2015 that were billed under workers' compensation at an academic ED. The following variables were collected: age, gender, mechanism of injury/exposure, diagnoses, imaging performed, specialty consultation, operative requirement, follow-up specialty, and ED disposition. In 2015, 377 patients presented to the ED for work-related injuries. The most common mechanism of injury was fall. Frequent diagnoses included lower extremity injuries and hand/finger injuries. The most common consulting service was orthopedics. Only five patients were referred to occupational medicine for follow up. Knowledge of the types of occupational injuries and subsequent care required may help guide both workers and employers how to best triage patients within the healthcare system. Alternative settings such as occupational medicine or primary care services may be appropriate for some patients. Copyright © 2018 Elsevier Inc. All rights reserved.

2015-08-01

The purpose of this study was to develop and test a hand therapy game using the Microsoft (Redmond, WA) Kinect(®) sensor with a customized videogame. Using the Microsoft Kinect sensor as an input device, a customized game for hand rehabilitation was developed that required players to perform various gestures to accomplish a virtual cooking task. Over the course of two iterative sessions, 11 participants with different levels of wrist, hand, and finger injuries interacted with the game in a single session, and user perspectives and feedback were obtained via a questionnaire and semistructured interviews. Participants reported high levels of enjoyment, specifically related to the challenging nature of the game and the visuals. Participant feedback from the first iterative round of testing was incorporated to produce a second prototype for the second round of testing. Additionally, participants expressed the desire to have the game adapt and be customized to their unique hand therapy needs. The game tested in this study has the potential to be a unique and cutting edge method for the delivery of hand rehabilitation for a diverse population.

The effects of musical training on the body in professional musicians remain an understudied area, particularly in reference to understanding and managing orthopedic/neuromuscular deviations and injuries in this population. The purpose of this study was to evaluate hand/finger fine motor function in musicians via physical examination as well as laboratory-based evaluations. Thirteen healthy noninjured young elite string musicians participated in this study. Performance of musicians was compared with healthy age-matched, sex-matched, and handedness-matched nonmusician controls. Musicians exhibited decreased intrinsic muscle strength compared with controls; however, no change in extrinsic muscle strength was found between groups. No between-group differences in overall force control were found; however, Group × Hand (right vs left) interactions were found in force control. These data suggest that musicians are a unique population with respect to: (1) fine motor control of the hand; and (2) exhibit changes in differential hand use. This suggests cortical reorganization of string musicians, such that this population should be studied separately from typical healthy controls with respect to hand function.

To report the clinical features of ocular injuries associated with explosive military ammunition in insurgent attacks in Turkey. The medical records of 48 casualties who were treated for ocular injuries sustained in insurgent attacks at the Combat Region Hospitals in Turkey were retrospectively reviewed. The reviewed data included initial visual acuity, type of explosive military ammunition (ie, improvised explosive device, mine, hand grenade and rocket-propelled grenade), type of globe injury (open-globe vs closed-globe injury), traumatised globe zones, the presence/absence of an intraocular foreign body, medical interventions, status during the explosion and injuries to other parts of the body. The visual acuity differences between different explosive materials and between 'on-foot' and 'inside-vehicle' casualties were investigated. A total of 83 injured eyes were analysed. The mean patient age was 24.5±6.6 years. The mean initial logarithm of the minimum angle of resolution visual acuity was 0.60±0.63. The injuries were due to improvised explosive devices in 28 cases (58.3%), land mines in 16 cases (33.3%), and hand grenades and rocket-propelled grenades in 2 cases each (4.2%). Forty-seven eyes (56.6%) had open-globe injuries. The most frequently involved zones were zone 1 (50.0%) in closed-globe injuries and all zones (31.9%) in open-globe injuries. Intraocular foreign bodies were present in 45/47 (95.7%) eyes with open-globe injuries. Twelve (14.4%) eyes with no light perception were enucleated, and two (2.4%) eviscerated. The difference in the visual acuities between the on-foot and inside-vehicle casualties and between the injuries that were caused by the different types of explosive ammunitions was also insignificant (p=0.271 and 0.394, respectively). The clinical results for eye injuries caused by explosive military ammunition sustained during insurgent attacks in Turkey are disappointing irrespective of the explosive material.

Explosion injuries to the upper extremity have specific clinical characteristics that differ from injuries due to other mechanisms. To evaluate the upper extremity injury pattern of attacks on civilian targets, comparing bomb explosion injuries to gunshot injuries and their functional recovery using standard outcome measures. Of 157 patients admitted to the hospital between 2000 and 2004, 72 (46%) sustained explosion injuries and 85 (54%) gunshot injuries. The trauma registry files were reviewed and the patients completed the DASH Questionnaire (Disabilities of Arm, Shoulder and Hand) and SF-12 (Short Form-12) after a minimum period of 1 year. Of the 157 patients, 72 (46%) had blast injuries and 85 (54%) had shooting injuries. The blast casualties had higher Injury Severity Scores (47% vs. 22% with a score of > 16, P = 0.02) and higher percent of patients treated in intensive care units (47% vs. 28%, P = 0.02). Although the Abbreviated Injury Scale score of the upper extremity injury was similar in the two groups, the blast casualties were found to have more bilateral and complex soft tissue injuries and were treated surgically more often. No difference was found in the SF-12 or DASH scores between the groups at follow up. The casualties with upper extremity blast injuries were more severely injured and sustained more bilateral and complex soft tissue injuries to the upper extremity. However, the rating of the local injury to the isolated limb is similar, as was the subjective functional recovery.

Two hundred and seventeen patients who had sustained an injury during the recreational use of a trampoline were managed in the emergency room of Logan Regional Hospital in Logan, Utah, from January 1991 through December 1992. We retrospectively reviewed the charts and radiographs of these patients to categorize the injuries. Additional details regarding the injuries of seventy-two patients (33 per cent) were obtained by means of a telephone interview with use of a questionnaire. The injuries occurred from February through November, with the peak incidence in July. The patients were eighteen months to forty-five years old (average, ten years old); ninety-four patients (43 per cent) were five to nine years old. Eighty-four patients (39 per cent) sustained a fracture; fifty-four (25 per cent), a sprain or strain; forty-five (21 per cent), a laceration; and thirty-four (16 per cent), a contusion. Fifty-seven injuries (26 per cent) involved the elbow or forearm; forty-six (21 per cent), the head or neck; forty (18 per cent), the ankle or foot; thirty-three (15 per cent), the knee or leg; nineteen (9 per cent), the trunk or back; thirteen (6 per cent), the shoulder or arm; and nine (4 per cent), the wrist or hand. Thirteen patients (6 per cent) had a back injury, but none of them had a permanent neurological deficit. One patient who had an ocular injury was transferred to a tertiary care center. One hundred and fifty-six patients (72 per cent) were evaluated radiographically, fifteen (7 per cent) were admitted to the hospital, and thirteen (6 per cent) had an operation.(ABSTRACT TRUNCATED AT 250 WORDS)

Understanding the position-specific musculoskeletal forces placed on the body of athletes facilitates treatment, prevention, and return-to-play decisions. While position-specific injuries are well documented in most major sports, little is known about the epidemiology of position-specific injuries in National Association for Stock Car Automobile Racing (NASCAR) drivers and pit crew. To investigate position-specific upper extremity injuries in NASCAR drivers and pit crew members. Descriptive epidemiological study. A retrospective chart review was performed to assess position-specific injuries in NASCAR drivers and pit crew members. Included in the study were patients seen by a single institution between July 2003 and October 2014 with upper extremity injuries from race-related NASCAR events or practices. Charts were reviewed to identify the diagnosis, mechanism of injury, and position of each patient. A total of 226 NASCAR team members were treated between July 2003 and October 2014. Of these, 118 injuries (52%) occurred during NASCAR racing events or practices. The majority of these injuries occurred in NASCAR changers (42%), followed by injuries in drivers (16%), carriers (14%), jack men (11%), fuel men (9%), and utility men (8%). The majority of the pit crew positions are at risk for epicondylitis, while drivers are most likely to experience neuropathies, such as hand-arm vibration syndrome. The changer sustains the most hand-related injuries (42%) on the pit crew team, while carriers commonly sustain injuries to their digits (29%). Orthopaedic injuries in NASCAR vary between positions. Injuries in NASCAR drivers and pit crew members are a consequence of the distinctive forces associated with each position throughout the course of the racing season. Understanding these forces and position-associated injuries is important for preventive measures and facilitates diagnosis and return-to-play decisions so that each team can function at its maximal efficiency.

Splenic injuries are often caused when snowboarders thrust their abdomens with their own left elbows after falling and hitting the ground. We report 10 snowboarders who suffered a splenic injury by accidentally thrusting their own elbow against their abdomen upon falling to the ground. Clinical presentation, postural analysis, and treatment are described. In an attempt to break the force while falling, snowboarders assumed 1 of 2 defensive postures that subsequently induced splenic injury: falling with an outstretched hand or falling with folded arms placed closely to the chest, that is, the fetal tuck posture. Snowboarders who fell in the outstretched hand posture developed more severe symptoms than those who fell in the fetal tuck posture. Herein, we discuss the mechanisms of such snowboarding-related splenic injury in detail and provide a review of the literature.

Burn injuries often lead to significant cosmetic and functional deformity. In the Orient, household electric rice cookers have caused a significant number of steam burns to infant hands. The clinical course and treatment outcome of these burns have been studied retrospectively in a review of the medical records of 79 pediatric patients treated for acute hand steam burns and of 38 other patients who underwent correction for postburn contracture. Electric rice cookers caused all of the acute pediatric steam burns treated at our institute. Of the 81 hands treated between 1995 and 1998, 38.3 percent healed with conservative treatment and 61.7 percent required skin grafting. The volar aspects of the index and middle fingers were those most frequently involved. Eighteen of 36 hands (50 percent) grafted with split-thickness skin developed late contractures requiring additional procedures. Among the 38 patients who underwent correction for postburn deformity, initial treatment was split-thickness grafting for 60.5 percent, full-thickness skin grafting for 7.9 percent, and spontaneous healing for 31.6 percent. Awareness among medical personnel and continued public education should be promoted to help prevent this unique type of pediatric steam burn from occurring.

Although a popular endeavor, boxing has fallen under increased scrutiny because of its association with traumatic brain injury. However, few studies have investigated the overall epidemiology of boxing injuries from representative samples, and no study has ever documented the incidence of injuries in female boxers. This study is a review of professional boxing data from the state of Nevada from September 2001 through March 2003. Medical and outcome data for all professional boxing matches occurring in Nevada between September 2001 and March 2003 (n = 524 matches) were analyzed on the basis of a pair-matched, case-control design. Cases were boxers who received an injury during the boxing matches. Boxers who were not injured served as control subjects. Both conditional and unconditional logistic regression models were used to assess risk factors for injury. The overall incidence rate of injury was 17.1 per 100 boxer-matches, or 3.4 per 100 boxer-rounds. Facial laceration accounted for 51% of all injuries, followed by hand injury (17%), eye injury (14%), and nose injury (5%). Male boxers were significantly more likely than female boxers to receive injuries (3.6 versus 1.2 per 100 boxer-rounds, P = 0.01). Male boxing matches also ended in knockouts and technical knockouts more often than did female matches (P < 0.001). The risk of injury for those who lost the matches was nearly twice the risk for the winners. Those who lost by knockout had double the risk of injury compared with those who lost by other means. Neither age nor weight was significantly associated with the risk of injury. The injury rate in professional boxing matches is high, particularly among male boxers. Superficial facial lacerations are the most common injury reported. Male boxers have a higher rate of knockout and technical knockouts than female boxers. Further research is necessary to determine the outcomes of injury, particularly the long-term neurologic outcome differences between sexes.

Data from a nationally representative sample of emergency departments for the 6-month period July through December 1992 were used to examine nonfatal occupational injuries sustained by adolescents aged 14 through 17 years. There were 679 occupational injuries, corresponding to an estimated 37,405 injuries nationwide. Males constituted 65.8% of the injury victims. The injury rate for males was 7.0 per 100 full-time employees, compared with 4.4 for females. Lacerations to the hand or finger accounted for 25.6% of all injuries. The majority of injuries occurred in retail trades (53.7%), which also had the highest rate (6.3 per 100 full-time employees). Seventy-one percent of the injuries in retail trade occurred in eating and drinking establishments. PMID:8154574

Ketonis, Constantinos; Dwyer, Joseph; Ilyas, Asif M.

2016-01-01

Background: Literature on open fracture infections has focused primarily on long bones, with limited guidelines available for open hand fractures. In this study, we systematically review the available hand surgery literature to determine infection rates and the effect of debridement timing and antibiotic administration. Methods: Searches of the MEDLINE, EMBASE, and Cochrane computerized literature databases and manual bibliography searches were performed. Descriptive/quantitative data were extracted, and a meta-analysis of different patient cohorts and treatment modalities was performed to compare infection rates. Results: The initial search yielded 61 references. Twelve articles (4 prospective, 8 retrospective) on open hand fractures were included (1669 open fractures). There were 77 total infections (4.6%): 61 (4.4%) of 1391 patients received preoperative antibiotics and 16 (9.4%) of 171 patients did not receive antibiotics. In 7 studies (1106 open fractures), superficial infections (requiring oral antibiotics only) accounted for 86%, whereas deep infections (requiring operative debridement) accounted for 14%. Debridement within 6 hours of injury (2 studies, 188 fractures) resulted in a 4.2% infection rate, whereas debridement within 12 hours of injury (1 study, 193 fractures) resulted in a 3.6% infection rate. Two studies found no correlation of infection and timing to debridement. Conclusions: Overall, the infection rate after open hand fracture remains relatively low. Correlation does exist between the administration of antibiotics and infection, but the majority of infections can be treated with antibiotics alone. Timing of debridement, has not been shown to alter infection rates. PMID:28344521

Efficacy of enzymatic debridement of deeply burned hands.

The burned hand is a common and difficult to care-for entity in the field of burns. Due to the anatomy of the hand (important and delicate structures crowded in a small limited space without sub-dermal soft tissue), surgical debridement of the burned tissue is technically difficult and may cause considerable complications and, therefore, should be performed judiciously. Selective enzymatic debridement of the burn wound can preserve the spontaneous epithelialisation potential and reduce the added injury to the traumatised tissue added by a surgical debridement. The aim of the study was to assess the implication of a selective enzymatic compound (Debrase(®) - Ds) in the special field of deep hand burns, by comparing the actual burn area that required surgical coverage after enzymatic debridement to the burn area clinically judged to require skin grafting prior to debridement. This was a retrospective data collection and analysis from 154 complete files of prospective, open-label study in 275 hospitalised, Ds-treated burn patients. A total of 69 hand burns diagnosed as 'deep' was analysed; 36% of the wounds required surgical intervention after enzymatic debridement; 28.6% of the total burned area estimated initially as deep was covered by skin graft (statistically significant p<0.001). Debridement of deep-hand burns with a selective enzymatic agent decreased the perceived full-thickness wound area and skin-graft use. Copyright © 2011 Elsevier Ltd and ISBI. All rights reserved.

High-voltage electric injuries have many manifestations, and an important complication is the damage of the central/peripheral nervous system. The purpose of this work was to assess the upper limb dysfunction in patients injured by high-voltage current. The evaluation consisted of analysis of patients' records, cutaneous-sensibility threshold, handgrip and pinch strength and a specific questionnaire about upper limb dysfunctions (DASH) in 18 subjects. All subjects were men; the average age at the time of the injury was 38 years. Of these, 72% changed job/retired after the injury. The current entrance was the hand in 94% and grounding in the lower limb in 78%. The average burned surface area (BSA) was 8.6%. The handgrip strength of the injured limb was reduced (p<0.05) and so also that of the three pinch types. The relationship between the handgrip strength and the DASH was statistically significant (p<0.001) as well as the relationship between the three pinch types (phand, principally in the median nerve area. These data indicate a reduction of the hand muscular strength and sensibility, reducing the function of the upper limb in patients who received high-voltage electrical shock.

This article is a retrospective review of patients who presented to Martin Luther King, Jr./Drew Medical Center with gunshot wounds and had either isolated or associated injuries to the hand. The following is an account of those injuries noting the location, soft-tissue or bony involvement, and interventional methods that were implemented in the treatment of these patients who resided primarily in South Central Los Angeles. Prompt evaluation and initiation of treatment is essential in the management of both high- and low-velocity gunshot wounds so as to decrease the potential morbidity that often follows. Society must also look at the prevalence of these injuries and address the underlying issues that often are the root of the acts of violence.

The biomechanical and mental strains placed on the surgeon while performing laparoscopic procedures are significantly higher compared with open surgical techniques. We undertook this study to assess the prevalence of surgeons' deleterious perceptions or injuries related to laparoscopic urologic surgery. Members of endourological society were mailed a questionnaire evaluating their laparoscopic experience, total number of standard laparoscopic surgeries (SLS), hand-assisted laparoscopic surgeries (HALS), and robotic-assisted laparoscopic surgeries (RALS) they performed. The subjects reported any neuromuscular or arthritic injuries sustained during laparoscopic surgery, and graded the degree of pain, numbness, and fatigue they experienced. A total of 73 urologists completed the questionnaires. The average responder was 44 years old, had completed a median of 117 procedures, and was performing 3 laparoscopic surgeries per week. Neuromuscular or arthritic symptoms during surgery were reported by 22 responders (30%), the most common was finger paresthesia (18%). At the conclusion of HALS, 45% of the surgeons suffered from hand and wrist numbness and 37% reported pain in these areas. A significant association was observed between the risk of sustaining injury during surgery and the total number of laparoscopic procedures performed by the responder (P = 0.016). RALS was the procedure least associated with injuries, and HALS the most. The laparoscopic operating theater is a hostile ergonomic environment. Surgeons' awareness of the common injuries associated with laparoscopic surgery and careful equipment adjustments before surgery are mandatory to minimize injury. Future improvements in instrument design according to ergonomic principles are highly warranted.

Scientific injury data in men's professional team handball injuries are rare and even less scientific information exists on injury prevention. In 2011, Germany's national second team handball league was restructured by merging the existing two regional leagues into one league. This study evaluates the injury patterns in professional team handball and compares the injury rates between the first and second league before and after the restructure. All players of Germany's national first and second men's team handball leagues have mandatory trauma insurance with the same insurance company. This retrospective cohort study analysed the injury data of three consecutive seasons 2010-2013 using standardized injury definitions. 1194 professional team handball players were included in this study. The majority of severe injuries affected the lower extremities, shoulders, and hands. The average injury incidence significantly differed between the first (4.9 injuries per 1000 h) and the second league (3.9 per 1000 h, p < 0.01). The injury incidence in the restructured second league had increased from 3.7 to 4.1 per 1000 h (p < 0.01) and prevalence from 67.1 to 79.3% (p < 0.001), thus almost to the same levels of the first league. The second league showed more time-loss injuries at all severity levels. This study yielded a high injury incidence after the restructure of the national second team handball league and presents details on prevalence, incidence, and patterns of injury in professional men's team handball. This study is an important basis for developing injury prevention strategies that should focus on the shoulders, hands, and lower extremities and on reducing the number of matches and travel burden.

Objectives The presence of intracranial lesions or epilepsy may lead to functional reorganization and hemispheric lateralization. We applied a clinical magnetoencephalography (MEG) protocol for the localization of the contralateral and ipsilateral S1 and M1 of the foot and hand in patients with non-lesional epilepsy, stroke, developmental brain injury, traumatic brain injury and brain tumors. We investigated whether differences in activation patterns could be related to underlying pathology. Methods Using dipole fitting, we localized the sources underlying sensory and motor evoked magnetic fields (SEFs and MEFs) of both hands and feet following unilateral stimulation of the median nerve (MN) and posterior tibial nerve (PTN) in 325 consecutive patients. The primary motor cortex was localized using beamforming following a self-paced repetitive motor task for each hand and foot. Results The success rate for motor and sensory localization for the feet was significantly lower than for the hands (motor_hand 94.6% versus motor_feet 81.8%, p < 0.001; sensory_hand 95.3% versus sensory_feet 76.0%, p < 0.001). MN and PTN stimulation activated 86.6% in the contralateral S1, with ipsilateral activation < 0.5%. Motor cortex activation localized contralaterally in 76.1% (5.2% ipsilateral, 7.6% bilateral and 11.1% failures) of all motor MEG recordings. The ipsilateral motor responses were found in 43 (14%) out of 308 patients with motor recordings (range: 8.3–50%, depending on the underlying pathology), and had a higher occurrence in the foot than in the hand (motor_foot 44.8% versus motor_hand 29.6%, p = 0.031). Ipsilateral motor responses tended to be more frequent in patients with a history of stroke, traumatic brain injury (TBI) or developmental brain lesions (p = 0.063). Conclusions MEG localization of sensorimotor cortex activation was more successful for the hand compared to the foot. In patients with neural lesions, there were signs of brain reorganization as

Three cases of ulnar post-traumatic aneurysms of the hand as a consequence of occupational injury are reported. In two cases arteriography examination confirmed the presence of ulnar aneurysm while in the third case we performed only Duplex-scanning. To avoid complications treatment was surgical, consisting of resection of the lesion with end-to-end anastomosis. Ulnar artery patency was confirmed by Duplex-scanning in the follow-up period and the patients were able to return to their jobs.

Severe hand traumata have a significant impact on our health system and on insurance companies, respectively. It is estimated that 33% of all occupational injuries and 9% of all invalidity pensions are due to severe hand trauma. Unfortunately, these high numbers are not only due to the severity of the trauma but to organisational deficiencies. Usually, the patient is treated at the general surgical emergency in the first place and only then forwarded to a microsurgeon. This redirection increases the time that is required for the patient to finally arrive at an expert for hand surgery. On the one hand, this problem can be explained by the population's lack of awareness for distinguished experts for hand and microsurgery, on the other hand, the emergency network, or emergency doctors in particular are not well informed about where to take a patient with a severe hand trauma - clearly a problem of communication between the hospitals and the ambulance. It is possible to tackle this problem, but put participating hand trauma centres have to work hand in hand as a network and thus exploit synergy effects. The French system "FESUM" is a good example for such a network and even comprises centres in Belgium and Switzerland. To improve the treatment of severe hand trauma, a similar alliance was initiated in Germany just recently. The pilot project "Hand Trauma Alliance" (www.handverletzung.com) was started in April 2013 and currently comprises two hospitals within the region of upper Bavaria. The network provides hand trauma replantation service on a 24/7 basis and aims at shortening the way from the accident site to the fully qualified hand surgeon, to improve the therapy of severe hand injuries and to optimise acute patient care in general. In order to further increase the alliance's impact it is intended to extend the project's scope from regional to national coverage - nevertheless, such an endeavour can only be done in collaboration with the German Society for Hand

Peripheral nerve injuries are challenging problems. Nerve transfers are one of many options available to surgeons caring for these patients, although they do not replace tendon transfers, nerve graft, or primary repair in all patients. Distal nerve transfers for the treatment of high ulnar nerve injuries allow for a shorter reinnervation period and improved ulnar intrinsic recovery, which are critical to function of the hand.

2001-08-01

This retrospective study, conducted at the Indian Oil Corporation Ltd. (Assam Oil Division) Hospital, Digboi, in a period of 5 yr amongst workers of IOC Ltd. (AOD) describes work-associated injuries. Out of 2320 cases of different types of injuries involving workers over this period, 820 (35.3%) occurred at the workplace. 1430 (61.6%) at home or other places and 70 (3.1%) occurred on way to the workplace. Burn injuries were found in 132 cases (5.8% of the total injuries), but constituted 12.6% of the accidents at the workplace. The majority of the other injuries were soft tissue injuries, including sprains 1288 (55.5%) and hand injuries 688 (29.5%). Major burns (above 20% BSB) were found only in 5 cases. The most common sites of involvement in minor burns were the hands (45 cases), the legs (35 cases) and face (20 cases) with the remaining involving the chest and abdomen. Scald injury was observed in 66/132 (50%) cases, contact burns in 13/132 (10%) cases, flame burns in 33/132 (25%) cases, chemical burns in 11/132 (8.3%), and electrical burns in 9/132 (7%) cases. Mortality was 1.5%. Working days lost (man-days loss) in burn injuries was found to be higher in comparison to other injuries of similar severity. Causation of industrial burns is discussed and importance of prevention of burns in industries has been emphasised.

Across the world, many species of nondomesticated animals dwell among humans in metropolitan areas. Rare animal bites pose a dilemma for hand surgeons, as they often result in operative injuries and recalcitrant infections. The authors treated an 85-year-old man who experienced severe cellulitis of the index finger following an opossum bite. This case prompted a systematic review of upper extremity injuries caused by species other than dogs, cats, snakes, and insects. The authors conducted a systematic review of PubMed and Scopus databases to identify relevant articles published between 1980 and 2016. Two reviewers critically appraised the studies that met inclusion and exclusion criteria. The hand infection in the man who sustained an opossum bite at the authors' institution was successfully treated with targeted antibiotic therapy, hand elevation, and splinting. Seventy-one articles met inclusion criteria for and were included in this systematic review. The vast majority of existing articles represent level IV and level V evidence. The relevant literature suggests that the majority of hand infections attributable to animal bites and stings are polymicrobial. Injuries secondary to aquatic animals appear to be the most frequently described in the literature, and hot water immersion should be used for the majority of envenomation attributable to aquatic species. Infections can often be treated with an aminopenicillin antibiotic combined with a beta-lactamase inhibitor. Given the variability in presentation and potential for sequelae such as soft-tissue necrosis and systemic reactions, hand surgeons should approach such upper extremity injuries with a high degree of caution.

To investigate the effectiveness of digital technology in repairing wounds of the hand and foot with anterolateral thigh flap. Between September 2013 and September 2014, 16 cases of wounds of the hand and foot were treated with the anterolateral thigh flap. There were 10 males and 6 females, with an average age of 31 years (range, 20-52 years). The causes included traffic accident injury in 8 cases, crushing injury by machine in 6 cases, burning injury in 1 case, and animal biting injury in 1 case. The locations of soft tissue defect were the dorsum of the foot in 5 cases, the ankle in 4 cases, the planta pedis in 1 case, and the hand and forearm in 6 cases. The time was 2 hours to 45 days from injury to hospitalization (mean, 14.3 days). All defects were associated with exposure of bone and tendon. The size of wound was from 9.0 cmx4.0 cm to 29.0 cmx8.5 cm. CT angiography (CTA) was performed before operation, and the appropriate perforator as well as the donor site was selected. Then the Mimics l5.0 software was used to reconstruct the data of CTA so as to locate the main perforators, design the three-dimensional models of the anterolateral thigh flap, and simulate operation. The flap was obtained according to preoperative plan during operation. The size of flaps varied from 11 cm x 5 cm to 31 cm x 10 cm. The donor sites were sutured directly in 14 cases and were repaired by free skin graft in 2 cases. The lateral femoral circumflex artery identified by Mimics l5.0 software before operation, as well as the starting position of its descending branch, the blood vessel diameter at start site, vascular distribution, the maximum cutting length of the vascular pedicle were consistent with the actual observation during operation. All flaps were harvested and were used to repair defect smoothly. Vascular crisis occurred in 1 flap after operation, and the other flaps survived successfully. The wounds and the incisions obtained healing by first intention, and grafted skin

Thermometric diagnosis of peripheral nerve injuries. Assessment of the diagnostic accuracy of a new practical technique.

The diagnosis of nerve injury using thermotropic liquid crystal temperature strips was compared blindly and prospectively against operative findings in 36 patients requiring surgical exploration for unilateral upper limb lacerations with suspected nerve injury. Thermotropic liquid crystal strips were applied to affected and non-affected segments in both hands in all subjects. A pilot study showed that a simple unilateral laceration without nerve injury results in a cutaneous temperature difference between limbs, but not within each limb. Thus, for detection of a nerve injury, comparison was made against the unaffected nerve distribution in the same hand. Receiver operating characteristic curve analysis showed that an absolute temperature difference > or = 1.0 degrees C was diagnostic of a nerve injury (area under the curve = 0.985, sensitivity = 100%, specificity = 93.8%). Thermotropic liquid crystal strip assessment is a new, reliable and objective method for the diagnosis of traumatic peripheral nerve injuries. If implemented in the acute setting, it could improve the reliability of clinical assessment and reduce the number of negative surgical explorations.

3 cases of head injury are described in the Bible: the death of Sisera by the hand of Jael (Judges 4: 21; 5: 25); the skull fractures of Avimelech incurred at the tower of Tevetz, (Judges, 9: 53, 54); and the slaying of Goliath by David, (Samuel I 17: 49-51). The various attempts to understand the mechanisms of these head injuries using philology, knowledge of the art of biblical warfare and modern medical considerations are reviewed. We try to identify the site of the mortal blow to Sisera's head, to understand why Avimelech asked to be killed, and to decide whether the giant from Gath was a rugged warrior or just an endocrinological cripple.

Patient participation in pressure injury prevention: giving patient's a voice.

Pressure injuries burden patients and healthcare organisations, with some preventative practices having little impact on prevalence reduction. Patient participation in care may be an effective pressure injury prevention strategy, yet patient preferences are unknown. The aim of this interpretive study was to describe patients' perceptions of their current and future role in pressure injury prevention. Semi-structured interviews were conducted with 20 adult inpatients recruited from four medical units, at two Australian metropolitan hospitals. Interview data were analysed using content analysis, with three categories emerging: 'experiencing pressure injuries'; 'participating in pressure injury prevention'; and 'resourcing pressure injury prevention and treatment'. These categories reflect the complex nature of participants' pressure injury experience. The findings suggest participants gather pressure injury knowledge from first-hand and vicarious experience; knowledge they bring to hospital. Most participants preferred a proactive pressure injury prevention role. Many identified barriers in the healthcare environment that impeded their participation and affected their experience of pressure injuries and pressure injury prevention. If patient participation as a pressure injury prevention strategy is to be considered, nurses and organisations need to view patients as partners. © 2013 Nordic College of Caring Science.

The art and science of photography in hand surgery.

2014-03-01

High-quality medical photography plays an important role in teaching and demonstrating the functional capacity of the hands as well as in medicolegal documentation. Obtaining standardized, high-quality photographs is now an essential component of many surgery practices. The importance of standardized photography in facial and cosmetic surgery has been well documented in previous studies, but no studies have thoroughly addressed the details of photography for hand surgery. In this paper, we provide a set of guidelines and basic camera concepts for different scenarios to help hand surgeons obtain appropriate and informative high-quality photographs. A camera used for medical photography should come equipped with a large sensor size and an optical zoom lens with a focal length ranging anywhere from 14 to 75 mm. In a clinic or office setting, we recommend 6 standardized views of the hand and 4 views for the wrist; additional views should be taken for tendon ruptures, nerve injuries, or other deformities of the hand. For intraoperative pictures, the camera operator should understand the procedure and pertinent anatomy in order to properly obtain high-quality photographs. When digital radiographs are not available and radiographic film must be photographed, it is recommended to reduce the exposure and change the color mode to black and white to obtain the best possible pictures. The goal of medical photography is to present the subject in an accurate and precise fashion. Copyright © 2014 American Society for Surgery of the Hand. Published by Elsevier Inc.

Repetitive forces and moments are among the work requirements of hand-rim wheelchair propulsion that are related to shoulder injuries. No previous research has been published about the influence of power-assisted wheelchair propulsion on these work requirements. The purpose of our study was therefore to determine the influence of power-assisted propulsion on shoulder biomechanics and muscle activation patterns. We also explored the theoretical framework for the effectiveness of power-assisted propulsion in preventing shoulder injuries by decreasing the work requirements of hand-rim wheelchair propulsion. Nine non-wheelchair users propelled a hand-rim wheelchair on a treadmill at 0.9 m/s. Shoulder biomechanics, and muscle activation patterns, were compared between propulsion with and without power-assist. Propulsion frequency did not differ significantly between the two conditions (Wilcoxon Signed Rank test/significance level/effect size:4/.314/-.34). During power-assisted propulsion we found significantly decreased maximum shoulder flexion and internal rotation angles (1/.015/-.81 and 0/.008/-.89) and decreased peak force on the rim (0/.008/-.89). This resulted in decreased shoulder flexion, adduction and internal rotation moments (2/.021/-.77; 0/.008/-.89 and 1/.011/-.85) and decreased forces at the shoulder in the posterior, superior and lateral directions (2/.021/-.77; 2/.008/-.89 and 2/.024/-.75). Muscle activation in the pectoralis major, posterior deltoid and triceps brachii was also decreased (2/.038/-.69; 1/.015/-.81 and 1/.021/-.77). Power-assist influenced the work requirements of hand-rim wheelchair propulsion by healthy subjects. It was primarily the kinetics at rim and shoulder which were influenced by power-assisted propulsion. Additional research with actual hand-rim wheelchair users is required before extrapolation to routine clinical practice. Copyright © 2011 Elsevier Ltd. All rights reserved.

Musculoskeletal loading during the round-off in female gymnastics: the effect of hand position.

Chronic elbow injuries from tumbling in female gymnastics present a serious problem for performers. This research examined how the biomechanical characteristics of impact loading and elbow kinematics and kinetics change as a function of technique selection. Seven international-level female gymnasts performed 10 trials of the round-off from a hurdle step to flic-flac with 'parallel' and 'T-shape' hand positions. Synchronized kinematic (3D-automated motion analysis system; 247 Hz) and kinetic (two force plates; 1,235 Hz) data were collected for each trial. Wilcoxon non-parametric test and effect-size statistics determined differences between the hand positions examined in this study. Significant differences (p < 0.05) and large effect sizes (ES > 0.8) were observed for peak vertical ground reaction force (GRF), anterior-posterior GRF, resultant GRF, loading rates of these forces and elbow joint angles, and internal moments of force in sagittal, transverse, and frontal planes. In conclusion, the T-shape hand position reduces vertical, anterior-posterior, and resultant contact forces and has a decreased loading rate indicating a safer technique for the round-off. Significant differences observed in joint elbow moments highlighted that the T-shape position may prevent overloading of the joint complex and consequently reduce the potential for elbow injury.

Adding insult to injury?: the untoward impact of requiring more than de minimis injury in an Eighth Amendment excessive force case.

This Note explores the conflict over whether a prisoner must suffer more than de minimis injury to sustain an Eighth Amendment excessive force claim. It examines this conflict against the backdrop of the various standards the U.S. Supreme Court adopted in its Eighth Amendment prison conditions jurisprudence between 1976 and 1992, principally focusing on the 1992 Hudson v. McMillian decision. Moreover, this Note considers the intersection of "the evolving standards of decency," the "hands-off doctrine," and the Eighth Amendment injury requirement. Ultimately, this Note advocates that excessive force--when meted out as punishment--violates the Eighth Amendment's prohibition on cruel and unusual punishment regardless of whether a prisoner's injuries are more than de minimis.

Background: Volar plate fixation with locked screws has become the preferred treatment of displaced distal radius fractures that cannot be managed nonoperatively. This treatment, however, is not without complication. The purpose of this study was to determine what percentage of hand surgeons, over a 12-month period, have experienced a tendon complication when using volar plates for the treatment of distal radius fractures. Methods: A total of 3022 hand surgeons were e-mailed a link to an online questionnaire regarding their observation and treatment of tendon injuries associated with volar plating of distal radius fractures. Responses were reported using descriptive statistics. Results: Of the 596 (20%) respondents, 199 (33%) surgeons reported encountering at least one flexor tendon injury after distal radius volar plating over the past year of practice. The flexor pollicis longus was the most commonly reported tendon injury (254, 75%). Palmaris longus grafting (118, 37%) and tendon transfer (114, 36%) were the most often reported treatments following this complication. A total of 216 respondents (36%) also encountered 324 cases of extensor tendon rupture after volar plating of distal radius fractures, with tendon transfer (88%) being the preferred treatment option. Conclusions: Both flexor and extensor tendon ruptures can be seen after volar plating of distal radius fractures. Surgeons should be aware of these complications. Critical assessment of hardware position at the time of index procedure is recommended to avoid complications. Long-term studies are needed to standardize approaches to managing tendon rupture following volar plating of distal radius fractures. PMID:27698628

Many people are unaware of the science underlying the biophysical properties of Soldier clothing and personal protective equipment, yet there is a well-refined biomedical methodology initiated by Army physiologists in World War II. This involves a methodical progression of systematic material testing technologies, computer modeling, and human testing that enables more efficient development and rapid evaluation of new concepts for Soldier health and performance. Sophisticated manikins that sweat and move are a central part of this testing continuum. This report briefly summarizes the evolution and use of one specialized form of the manikin technologies, the thermal hand model, and its use in research on Soldier hand-wear items that sustain dexterity and protect the hand in extreme environments. Thermal manikin testing methodologies were developed to provide an efficient and consistent analytical tool for the rapid evaluation of new clothing concepts. These methods have been upgraded since the original World War II and Korean War eras to include articulation and sweating capabilities, as characterized and illustrated in this article. The earlier "retired" versions of thermal hand models have now been transferred to the National Museum of Health and Science. The biophysical values from manikin testing are critical inputs to the U.S. Army Research Institute of Environmental Medicine mathematical models that provide predictions of soldier comfort, duration of exposure before loss of manual dexterity, and time to significant risk of freezing (skin temperature <-1°C) and nonfreezing cold injuries (skin temperature <5°C). The greater thickness of better insulated handwear reduces dexterity and also increases surface area which makes added insulation increasingly less effective in retaining heat. Measurements of both thermal resistance (insulation) and evaporative resistance (permeability) collectively characterize the biophysical properties and enable mathematical

Raynaud's phenomenon and neurosensory symptoms are common after hand-arm vibration exposure. Knowledge of early signs of vibration injuries is needed. To investigate the risk of developing Raynaud's phenomenon and paraesthesia in relation to sensation of cold hands in a cohort of male employees at an engineering plant. We followed a cohort of male manual and office workers at an engineering plant in Sweden for 21 years. At baseline (1987 and 1992) and each follow-up (1992, 1997, 2002, 2008), we assessed sensation of cold, Raynaud's phenomenon and paraesthesia in the hands using questionnaires and measured vibration exposure. We calculated risk estimates with univariate and multiple logistic regression analyses and adjusted for vibration exposure and tobacco usage. There were 241 study participants. During the study period, 21 individuals developed Raynaud's phenomenon and 43 developed paraesthesia. When adjusting the risk of developing Raynaud's phenomenon for vibration exposure and tobacco use, the odds ratios were between 6.0 and 6.3 (95% CI 2.2-17.0). We observed no increased risk for paraesthesia in relation to a sensation of cold hands. A sensation of cold hands was a risk factor for Raynaud's phenomenon. At the individual level, reporting a sensation of cold hands did not appear to be useful information to predict future development of Raynaud's phenomenon given a weak to moderate predictive value. For paraesthesia, the sensation of cold was not a risk factor and there was no predictive value at the individual level.

2018-05-01

Measurement of grip force is important for both exercise training and assessment of the hand during physical rehabilitation. The standard method uses a grip dynamometer which measures the force between the fingers and opposing thumb. The primary limitation of the grip dynamometer is the restriction of measurement to cylindrical grasps. Any deformation of the hand due to muscular or skeletal disease makes the grip dynamometer difficult or impossible to use. An alternative to the grip dynamometer is a sealed pneumatic object that can be gripped by the hand. Measurement of the internal pressure in the object can be related to the grip force. In this paper, we analyze such a pneumatic pressure sensing object for hand grip assessment and also describe an easy fabrication of the grip sensor. The instrumented object presented in this paper is designed to assess both the maximal voluntary grip forces and continuous grip force to monitor control of hand function during exercise under instruction from a therapist. Potential uses of such a pneumatic pressure sensing object for hand grip are in physical rehabilitation of patients following paralysing illnesses like stroke and spinal cord injury.

Injury to the cervical spinal cord results in bilateral deficits in arm/hand function reducing functional independence and quality of life. To date little research has been undertaken to investigate control strategies of arm/hand movements following cervical spinal cord injury (cSCI). This study aimed to investigate unimanual and bimanual coordination in patients with acute cSCI using 3D kinematic analysis as they performed naturalistic reach to grasp actions with one hand, or with both hands together (symmetrical task), and compare this to the movement patterns of uninjured younger and older adults. Eighteen adults with a cSCI (mean 61.61 years) with lesions at C4-C8, with an American Spinal Injury Association (ASIA) grade B to D and 16 uninjured younger adults (mean 23.68 years) and sixteen uninjured older adults (mean 70.92 years) were recruited. Participants with a cSCI produced reach-to-grasp actions which took longer, were slower, and had longer deceleration phases than uninjured participants. These differences were exacerbated during bimanual reach-to-grasp tasks. Maximal grasp aperture was no different between groups, but reached earlier by people with cSCI. Participants with a cSCI were less synchronous than younger and older adults but all groups used the deceleration phase for error correction to end the movement in a synchronous fashion. Overall, this study suggests that after cSCI a level of bimanual coordination is retained. While there seems to be a greater reliance on feedback to produce both the reach to grasp, we observed minimal disruption of the more impaired limb on the less impaired limb. This suggests that bimanual movements should be integrated into therapy.

Rehabilitation interventions for the hand have shown benefits for children with Hemiplegia due to cerebral palsy or traumatic brain injury. Longer interventions are facilitated if training is provided in the patient's home, due to easier access to care and reduced impact on school or work activities. Providing remote rehabilitation over lengthy periods of time has however its own challenges. This paper presents two pediatric patients with hemiplegia, who practiced virtual hand rehabilitation games using a modified PlayStation 3 and 5DT sensing gloves. Despite severe initial hand spasticity, and occasional technology shortcomings, the subjects practiced for about 14 months, and 6 months, respectively. Game performance data for the second patient is presented. Follow-up evaluations 14 months from the removal of the PlayStation 3 from the home of the child with cerebral palsy showed that the patient had good retention in terms of grasp strength, hand function and bone health. Challenges of long-term home tele-rehabilitation are also discussed.

Reaching and grasping impairments significantly affect the quality of life for people who have experienced a stroke or spinal cord injury. The long-term well-being of patients varies greatly according to the restorable residual capabilities. Electrical stimulation could be a promising solution to restore motor functions in these conditions, but its use is not clinically widespread. Here, we introduce the HandNMES, an electrode array (EA) for neuromuscular electrical stimulation (NMES) aimed at grasp training and assistance. The device was designed to deliver electrical stimulation to extrinsic and intrinsic hand muscles. Six independent EAs, positioned on the user forearm and hand, deliver NMES pulses originating from an external stimulator equipped with demultiplexers for interfacing with a large number of electrodes. The garment was designed to be adaptable to user needs and anthropometric characteristics; size, shape, and contact materials can be customized, and stimulation characteristics such as intensity of stimulation and virtual electrode location, and size can be adjusted. We performed extensive tests with nine healthy subjects showing the efficacy of the HandNMES in terms of stimulation performance and personalization. Because encouraging results were achieved, in the coming months, the HandNMES device will be tested in pilot clinical trials.

Reanimating the arm and hand with intraspinal microstimulation

To date, there is no effective therapy for spinal cord injury, and many patients could benefit dramatically from at least partial restoration of arm and hand function. Despite a substantial body of research investigating intraspinal microstimulation (ISMS) in frogs, rodents and cats, little is known about upper-limb responses to cervical stimulation in the primate. Here, we show for the first time that long trains of ISMS delivered to the macaque spinal cord can evoke functional arm and hand movements. Complex movements involving coordinated activation of multiple muscles could be elicited from a single electrode, while just two electrodes were required for independent control of reaching and grasping. We found that the motor responses to ISMS were described by a dual exponential model that depended only on stimulation history. We demonstrate that this model can be inverted to generate stimulus trains capable of eliciting arbitrary, graded motor responses, and could be used to restore volitional movements in a closed-loop brain-machine interface.

There were 3 objectives for this prospective quasiexperimental study. The first was to determine the effect of mentor's hand hygiene practices on student's hand hygiene rates during clinical rotations. The second was to assess the difference in hand hygiene rates for students with and without prior medical experience. The third was to assess the student's opinion and beliefs regarding hand hygiene. Sixty students enrolled in a certified nursing program were selected to participate in the study. Each study group was observed twice during the 30-day span. The first observational period was conducted on day 1 of clinical rotation. The second observational period was conducted on day 30 of clinical rotation. Students were observed for hand hygiene. Also assessed were medical experience, sex, gloving, age, and mentor's hand hygiene practices. After observational period 2, a brief questionnaire was given to students to determine their opinion and beliefs regarding hand hygiene. The questionnaire was divided into 5 sections: student's commitment to hand hygiene, their perception of hand hygiene inconvenience, the necessity of hand hygiene, the student's ability to perform hand hygiene, and their opinion on the frequency of medical staff's hand hygiene. The mentor's practice of hand hygiene was the strongest predictor of the student's rate of hand hygiene for both observational periods (P < .01). Furthermore, students without prior medical experience had a significant increase in hand hygiene rates when comparing observational period 1 to observational period 2 (P < .01). Glove usage was associated with increased hand hygiene rates by 50% during observational period 1 (P = .01) and 44% during observational period 2 (P < .01). Male students during observational period 1 practiced hand hygiene 30% less often than female students (P < .01); however, during observational period 2, there was no significant difference between hand hygiene rates for males and females (P = .82

Outcomes after hand and upper extremity transplantation.

2017-05-01

Hand and upper extremity transplantation (HUET) has emerged as the most frequently performed reconstructive procedure in the burgeoning field of vascularized composite allotransplantation (VCA). VCA refers to a form of transplant with multiple tissue types that represents a viable treatment option for devastating injuries where conventional reconstruction would be unable to restore form and function. As hand transplantation becomes increasingly more common, discussions on advantages and disadvantages of the procedure seem to intensify. Despite encouraging functional outcomes, current immunosuppressive regimens with their deleterious side-effect profile remain a major concern for a life-changing but not life-saving type of transplant. In addition, a growing number of recipients with progressively longer follow-up prompt the need to investigate potential long-term sequelae, such as chronic rejection. This review will discuss the current state of HUET, summarizing outcome data on graft survival, motor and sensory function, as well as immunosuppressive treatment. The implications of these findings for VCA in terms of achievements and challenges ahead will then be discussed.

Back to basics: hand hygiene and surgical hand antisepsis.

Spruce, Lisa

Health care-associated infections (HAIs) are a significant issue in the United States and throughout the world, but following proper hand hygiene practices is the most effective and least expensive way to prevent HAIs. Hand hygiene is inexpensive and protects patients and health care personnel alike. The four general types of hand hygiene that should be performed in the perioperative environment are washing hands that are visibly soiled, hand hygiene using alcohol-based products, surgical hand scrubs, and surgical hand scrubs using an alcohol-based surgical hand rub product. Barriers to proper hand hygiene may include not thinking about it, forgetting, skin irritation, a lack of role models, or a lack of a safety culture. One strategy for improving hand hygiene practices is monitoring hand hygiene as part of a quality improvement project, but the most important aspect for perioperative team members is to set an example for other team members by following proper hand hygiene practices and reminding each other to perform hand hygiene.

Adolescent Daughters and Ritual Abjection: Narrative Analysis of Self-injury in Four US Films.

PubMed

Bareiss, Warren

2017-09-01

Media representations of illnesses, particularly those associated with stigma such as non-suicidal self-injury (NSSI), not only define health conditions for mass audiences, but generally do so in ways that are consistent with dominant ideologies. This article examines the construction of non-suicidal self-injury as practiced by female adolescents and young adults in four US films: Girl, Interrupted, Painful Secrets, Prozac Nation, and Thirteen. The methodology used to examine the films' narrative structure is Kenneth Burke's dramatism, while Julia Kristeva's concept of abjection informs the analysis. On one hand, a paradigmatic reading suggests that the films frame self-injury as resistance to repressive maternal domination of female adolescents. On the other hand, syntagmatic analysis reveals a privileged response to NSSI in the form of pacification administered by psychotherapists functioning as the return of the phallic-mother fantasy.

The purpose of this systematic review was to determine the effectiveness of passive physical modalities compared to other interventions, placebo/sham interventions, or no intervention in improving self-rated recovery, functional recovery, clinical outcomes and/or administrative outcomes (eg, time of disability benefits) in adults and/or children with soft tissue injuries and neuropathies of the wrist and hand. We systematically searched MEDLINE, EMBASE, PsycINFO, and the Cochrane Central Register of Controlled Trials, accessed through Ovid Technologies, Inc, and CINAHL Plus with Full Text, accessed through EBSCO host, from 1990 to 2015. Our search strategies combined controlled vocabulary relevant to each database (eg, MeSH for MEDLINE) and text words relevant to our research question and the inclusion criteria. Randomized controlled trials, cohort studies, and case-control studies were eligible. Random pairs of independent reviewers screened studies for relevance and critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with low risk of bias were synthesized following best evidence synthesis principles. We screened 6618 articles and critically appraised 11 studies. Of those, 7 had low risk of bias: 5 addressed carpal tunnel syndrome (CTS) and 2 addressed de Quervain disease. We found evidence that various types of night splints lead to similar outcomes for the management of CTS. The evidence suggests that a night wrist splint is less effective than surgery in the short term but not in the long term. Furthermore, a night wrist splint and needle electroacupuncture lead to similar outcomes immediately postintervention. Finally, low-level laser therapy and placebo low-level laser therapy lead to similar outcomes. The evidence suggests that kinesio tape or a thumb spica cast offers short-term benefit for the management of de Quervain disease. Our search did not identify any low risk of bias studies examining the

Regular physical activity is important for people with tetraplegia to maintain fitness but may not always be easily integrated into daily life. In many countries, hand cycling has become a serious option for daily mobility in people with tetraplegia. However, little information exists regarding the suitability of this exercise mode for this population. The purpose of this study was to evaluate the effects of a structured hand cycle training program in individuals with chronic tetraplegia. Pretraining and posttraining outcome measurements of physical capacity were compared. Structured hand cycle interval training was conducted at home or in a rehabilitation center in the Netherlands. Twenty-two patients with tetraplegia (American Spinal Injury Association Impairment Scale classification A-D) at least 2 years since injury participated. The intervention was an 8- to 12-week hand cycle interval training program. Primary outcomes of physical capacity were: peak power output (POpeak) and peak oxygen uptake (Vo(2)peak), as determined in hand cycle peak exercise tests on a motor-driven treadmill. Secondary outcome measures were: peak muscle strength (force-generating capacity) of the upper extremities (as assessed by handheld dynamometry), respiratory function (forced vital capacity and peak expiratory flow) and participant-reported shoulder pain. Significant improvements following a mean of 19 (SD=3) sessions of hand cycle training were found in POpeak (from 42.5 W [SD=21.9] to 50.8 W [SD=25.4]), Vo(2)peak (from 1.32 L.min(-1) [SD=0.40] to 1.43 L.min(-1) [SD=0.43]), and mechanical efficiency, as reflected by a decrease in submaximal oxygen uptake. Except for shoulder abduction strength, no significant effects were found on the secondary outcomes. Common health complications, such as urinary tract infections, bowel problems, and pressure sores, led to dropout and nonadherence. Patients with tetraplegia were able to improve their physical capacity through regular hand cycle

Efficacy of Low Level Laser Therapy After Hand Flexor Tendon Repair

Ayad, K. E.; Abd El Mejeed, S. F.; El Gohary, H. M.

Flexor tendon injury is a common problem requiring suturing repair followed by early postoperative mobilization. Muscle atrophy, joint stiffness, osteoarthritis, infection, skin necrosis, ulceration of joint cartilage and tendocutaneous adhesion are familiar complications produced by prolonged immobilization of surgically repaired tendon ruptures. The purpose of this study was to clarify the importance of low level laser therapy after hand flexor tendon repair in zone II. Thirty patients aging between 20 and 40 years were divided into two groups. Patients in group A (n = 15) received a conventional therapeutic exercise program while patients in group B (n = 15) receivedmore » low level laser therapy combined with the same therapeutic exercise program. The results showed a statistically significant increase in total active motion of the proximal and distal interphalangeal joints as well as maximum hand grip strength at three weeks and three months postoperative, but improvement was more significant in group B. It was concluded that the combination of low level laser therapy and early therapeutic exercises was more effective than therapeutic exercises alone in improving total active motion of proximal and distal interphalangeal joints and hand grip strength after hand flexor tendon repair.« less

The growth in participation in men's lacrosse has increased the likelihood of sport-specific injuries, yet there continues to be a need for specific epidemiological data concerning lacrosse injuries. The purpose of this literature review is to aggregate available published data on injuries that occur in the sport of men's lacrosse at the youth, high school, collegiate, and professional levels. A comprehensive literature search was performed in PubMed, High Wire Press, SPORTDiscus, Google Scholar, and Ovid, using the keywords Lacrosse Injuries, Epidemiology Lacrosse Injuries, Lacrosse Injury, Lacrosse AND Injury and limited to 1990-2016. All bibliographies were cross-referenced to identify any additional publications. Sources were categorized based on data provided and were aggregated into groups based on reported overall injury rates, rates by setting (competition vs. practice), nature of injury, location, type, severity, and player position. The game and practice injury rates in college are greater than the rates in high school, similarly rates greater for high school players than in youth leagues. Rates of injury varied from 0.095-12.98 per 1000 athlete exposures. Game injury rates were higher across all studies. Injuries in men's lacrosse occur most often from player-to-player contact, which result in immediate injuries, such as concussions, contusions, and lacerations. Overall concussion incidence was reported to range from 0.11-0.84 per 1000 AE. The most common types of injuries were sprain, strain, concussion, and contusions and the most common area of injury was hand (23%), with a significant proportion of these (59.4%) being to the thumb. Limited evidence of different injuries among the player positions suggests there might be a pattern that midfield players had the most injuries, followed by offensive players and then defensive players. The potential for sports-related injury is of relative concern; especially considering rising participation and total

Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

Children and adolescents spend up to 50% of their time at school. The purpose of this study was to assess injury patterns with their treatment of school accidents in a Trauma Service of a German University Hospital and to compare these data to the literature. All school accidents from 01.07.1999 to 30.06.2004 were statistically analysed in a retrospective manner by chart review. There were 1399 school accidents treated in our department. Average age of the injured children was 11.8 years with a boy:girl ratio of 3:2. Almost 40% of the injuries occurred during school sport. The most frequently injured region was the upper extremity including the hand (36.8%). Distortion and contusion were the most frequent diagnoses of all injuries. 16% of the cases had to be treated surgically and/or under general anaesthesia and also a total of 16% of the patients had to be admitted to the hospital. It can be concluded for school facilities that special attention has to be paid during school sports activity and breaks because they account for most accidents. Traffic education may reduce severe injuries. For diagnosis and treatment of school accidents specific knowledge of the growing longbones of the upper extremity and the hand is important.

Suitable grip strength is a police occupational requirement. The aim of this study was to investigate the association between grip strength, task performance and injury risk in a police population. Retrospective data of police recruits (n = 169) who had undergone basic recruit training were provided, including handgrip strength results, occupational task performance measures (consisting of police task simulations [SIM], tactical options [TACOPS] and marksmanship assessments) and injury records. Left hand grip strength (41.91 ± 8.29 kg) measures showed a stronger correlation than right hand grip strength (42.15 ± 8.53 kg) with all outcome measures. Recruits whose grip strength scores were lower were significantly more susceptible to failing the TACOPS occupational task assessment than those with greater grip strength scores, with significant (p ≤ 0.003) weak to moderate, positive correlations found between grip strength and TACOPS performance. A significant (p < 0.0001) correlation was found between grip strength, most notably of the left hand, and marksmanship performance, with those performing better in marksmanship having higher grip strength. Left hand grip strength was significantly associated with injury risk (r = −0.181, p = 0.018) but right hand grip strength was not. A positive association exists between handgrip strength and police recruit task performance (notably TACOPS and marksmanship) with recruits who scored poorly on grip strength being at greatest risk of occupational assessment task failure.

There are an estimated 2.75 million electronic cigarette (EC) users in the United States. ECs have become the most commonly used nicotine-containing product in young adults ages 18-24 years. Thermal, blast, and missile injuries from EC explosions has grown rapidly in recent years. Burn surgeons must remain up to date regarding management and treatment of burn injuries related to EC device ignition. An IRB approved retrospective review of all patients admitted to the Massachusetts General Hospital Burn Center from January 2015 to April 2017 was performed. Fourteen patients with injuries associated with EC use were identified. Patient demographics, injury location, size and degree of burn, treatments required, length of stay (LOS), time to 95% closure, associated complications and injuries, and the circumstances that led to the injury were identified. The mean age was 28.6±8.6 years with a range of 19-50 years (n=14). EC burns occurred in males 93% (13/14) of the time. The majority of EC explosions caused 2nd and 3rd degree burns (57%) within the same wound bed, followed by deep 2nd degree (29%), and superficial 2nd degree (14%). The average TBSA from EC burns was 4.7±2.4% with a range of 1-10%. The most common location of the device or battery at the time of the injury was a pant pocket 86% (12/14), followed by 7% hand (1/14) and 7% purse (1/14). Isolated lower extremity burns occurred in 43% (6/14) of patients, while lower extremity and hand burns occurred in 21% (3/14) of patients. Nine of 14 patients required an operating room encounter under general anesthesia. Eight of 14 patients required skin grafting for definitive wound closure. The mean hospital length of stay was 6.6±4.7 days with a range of 0-15 days. Time to 95% wound closure was 18.4±10.8 with a range of 8-40 days. Thermal and blast injuries associated with EC device failure tend to cause small TBSA burns that are deep 2nd and 3rd degree wounds. The most common location for EC device storage among

Context: Lower extremity injuries are common in basketball, yet it is unclear how prophylactic interventions affect lower extremity injury incidence rates. Objective: To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. Data Sources: PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Study Selection: Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 2. Data Extraction: Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Results: Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P < 0.001) and ankle sprains (OR, 0.45; 95% CI, 0.29-0.69; P < 0.001), yet not ACL ruptures (OR, 1.09; 95% CI, 0.36-3.29; P = 0.87) in basketball athletes. Conclusion: In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. PMID

Ballistic fractures of the carpus and hand are routinely treated in large urban centers. These injuries can be challenging due to many factors. Various treatment options exist for these complicated injuries, but there are limited data available. This report analyzes patient demographics, treatments, and outcomes at a large urban trauma center. All ballistic fractures of the hand and wrist of the patients who presented to a single center from 2011 to 2014 were retrospectively reviewed. Patient demographics, injury mechanism, treatment modalities, and outcomes were analyzed. Seventy-seven patients were identified; 70 were male, and 7 were female. Average age of the patients was 29.6 years. Seventy-five injuries were low velocity, whereas 2 were high velocity. Sixty-seven patients had fractures of a metacarpal or phalanx, whereas 4 had isolated carpal injuries. Six had combined carpal and metacarpal or phalanx fractures. Thirty-six patients had concomitant tendon, nerve, or vascular injuries requiring repair. Sixty-three patients underwent operative intervention, with the most common intervention being percutaneous fixation. Sixteen patients required secondary surgery. Eighteen complications were reported. The majority of patients in this report underwent early operative intervention with percutaneous fixation. Antibiotics were administered in almost all cases and can usually be discontinued within 24 hours after surgery. It is important to consider concomitant nerve, vascular, or tendon injuries requiring repair. We recommend early treatment of these injuries with debridement and stabilization. Due to lack of follow-up and patient noncompliance, early definitive treatment with primary bone grafting should be considered.

Hand preference and skilled hand performance among individuals with successful rightward conversions of the writing hand.

PubMed

Porac, Clare

2009-03-01

Searleman and Porac (2001) studied lateral preference patterns among successfully switched left-hand writers, left-hand writers with no switch pressure history, and left-hand writers who did not switch when pressured. They concluded that left-handers who successfully shift to right-hand writing are following an inherent right-sided lateralisation pattern that they already possess. Searleman and Porac suggested that the neural mechanisms that control lateralisation in the successfully switched individuals are systematically different from those of other groups of left-handers. I examined patterns of skilled and less-skilled hand preference and skilled hand performance in a sample of 394 adults (ages 18-94 years). The sample contained successfully switched left-hand writers, left-handers pressured to shift who remained left-hand writers, left-handers who did not experience shift pressures, and right-handers. Both skilled hand preference and skilled hand performance were shifted towards the right side in successfully switched left-hand writers. This group also displayed mixed patterns of hand preference and skilled hand performance in that they were not as right-sided as "natural" right-handers nor were they as left-sided as the two left-hand writing groups, which did not differ from each other. The experience of being pressured to switch to right-hand writing was not sufficient to shift lateralisation patterns; the pressures must be experienced in the context of an underlying neural control mechanism that is amenable to change as a result of these external influences.

Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p < 0.05) with age: 8 to 13 > 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p < 0.05). Evaluation of only the nonaccidental injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p < 0.001). Two thirds of the injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p < 0.001). The study findings indicate that children have lower risk of resistance training-related joint sprains and muscle strains than adults. The majority of youth resistance training injuries are the result of accidents that are

Damage to the motor cortex of one hemisphere has classically been associated with contralateral upper limb paresis, but recent patient studies have identified deficits in both upper limbs. In non-human primates, we tested the hypothesis that the severity of ipsilesional upper limb motor impairment in the early post-injury phase depends on the volume of gray and white matter damage of the motor areas of the frontal lobe. We also postulated that substantial recovery would accompany minimal task practice and that ipsilesional limb recovery would be correlated with recovery of the contralesional limb. Gross (reaching) and fine hand motor functions were assessed for 3-12 months post-injury using two motor tests. Volumes of white and gray matter lesions were assessed using quantitative histology. Early changes in post-lesion motor performance were inversely correlated with white matter lesion volume indicating that larger lesions produced greater decreases in ipsilesional hand movement control. All monkeys showed improvements in ipsilesional hand motor skill during the post-lesion period, with reaching skill improvements being positively correlated with total lesion volume indicating larger lesions were associate with greater ipsilesional motor skill recovery. We suggest that reduced trans-callosal inhibition from the lesioned hemisphere may play a role in the observed skill improvements. Our findings show that significant ipsilesional hand motor recovery is likely to accompany injury limited to frontal motor areas. In humans, more pronounced ipsilesional motor deficits that invariably develop after stroke may, in part, be a consequence of more extensive subcortical white and gray matter damage. PMID:21703261

Introduction Although death due to electrical injury and lightning are rare in children, these injuries are often preventable. Twenty years ago, most injuries occurred at home, precipitated by oral contact with electrical cords, contact with wall sockets and faulty electrical equipment. We sought to assess the epidemiology of electrical injuries in children presenting to Emergency Departments (EDs) that participate in the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP). This study is a retrospective review of electrical and lightning injury data from CHIRPP. The study population included children and youth aged 0-19 presenting to participating CHIRPP EDs from 1997-2010. Age, sex, year, setting, circumstance and disposition were extracted. Variables were tested using Fisher's exact test and simple linear regression. The dataset included 1183 electrical injuries, with 84 (7%) resulting in hospitalization. Most events occurred at home in the 2-5 year age group and affected the hands. Since 1997 there has been a gradual decrease in the number of electrical injuries per year (p<0.01) and there is an annual surge in electrical injuries over the summer (p<0.01). Forty-six percent of injuries involved electrical outlets, 65% of injuries involved some sort of electrical equipment. Injuries due to lightning were rare (n=19). No deaths were recorded in the database. Despite the decrease in the number of electrical injuries per year, a large portion of injuries still appear to be preventable. Further research should focus on effective injury prevention strategies.

Injury to the male external genitalia: a comprehensive review.

While rare, trauma and injury to the male external genitalia can result in significant consequences regarding function, appearance, psychological effects, and overall quality of life. Due to the relative paucity of literature regarding male external genitalia injuries, few standardized protocols exist. This review aims to outline common clinical causes of male external genitalia injuries by both anatomic location and etiology. Initial stabilization, long-term reconstruction, and coverage options are discussed in detail. Outcomes of complex grafts have favorable success rates of 90-100% in the hands of experienced surgeons. Outcomes of penile, testicular trauma also have favorable outcomes when managed appropriately. Attempts at reconstruction after initial injury stabilization should be undertaken at high-volume centers where a multidisciplinary approach can be employed. This manuscript will be an excellent reference and source that can provide direction for evaluation and management of these complex presentations.

Bimanual reach to grasp movements after cervical spinal cord injury

Injury to the cervical spinal cord results in bilateral deficits in arm/hand function reducing functional independence and quality of life. To date little research has been undertaken to investigate control strategies of arm/hand movements following cervical spinal cord injury (cSCI). This study aimed to investigate unimanual and bimanual coordination in patients with acute cSCI using 3D kinematic analysis as they performed naturalistic reach to grasp actions with one hand, or with both hands together (symmetrical task), and compare this to the movement patterns of uninjured younger and older adults. Eighteen adults with a cSCI (mean 61.61 years) with lesions at C4-C8, with an American Spinal Injury Association (ASIA) grade B to D and 16 uninjured younger adults (mean 23.68 years) and sixteen uninjured older adults (mean 70.92 years) were recruited. Participants with a cSCI produced reach-to-grasp actions which took longer, were slower, and had longer deceleration phases than uninjured participants. These differences were exacerbated during bimanual reach-to-grasp tasks. Maximal grasp aperture was no different between groups, but reached earlier by people with cSCI. Participants with a cSCI were less synchronous than younger and older adults but all groups used the deceleration phase for error correction to end the movement in a synchronous fashion. Overall, this study suggests that after cSCI a level of bimanual coordination is retained. While there seems to be a greater reliance on feedback to produce both the reach to grasp, we observed minimal disruption of the more impaired limb on the less impaired limb. This suggests that bimanual movements should be integrated into therapy. PMID:28384247

Among the various incidents in industrial radiography, inadvertent handling of sources by hands is one of the most frequent incidents in which some parts of the hands may be locally exposed to high doses. An accurate assessment of extremity dose assists medical doctors in selecting appropriate treatments, preventing the injury expansion in the region. In this study, a phantom was designed to simulate a fisted hand of a radiographer when the worker holds a radioactive source in their hands. The local doses were measured using implanted TLDs in the phantom at different distances from a source. Furthermore, skin dose distribution was measured by Gaf-chromic films in the palm region of the phantom. The reliability of the measurements has been studied via analytical as well as Monte-Carlo simulation methods. The results showed that the new phantom design can be used reliably in extremity dose assessments, particularly at the points next to the source.

Although sliding occurs frequently in professional baseball, little is known about the epidemiology and effect of injuries that occur during sliding in this population of elite athletes. To describe the incidence and characteristics of sliding injuries, determine their effect in terms of time out of play, and identify common injury patterns that may represent appropriate targets for injury prevention programs in the future. Descriptive epidemiologic study. All offensive sliding injuries occurring in Major League Baseball (MLB) and Minor League Baseball (MLB) that resulted in time out of play during a span of 5 seasons (2011-2015) were identified. In addition to player demographics, data extracted included time out of play, location on field where injury occurred, level of play, treatment (surgical vs nonsurgical), direction of slide (head vs feet first), body region injured, and diagnosis. Descriptive statistics were used to describe the distribution of these injuries, and injury rates were calculated per slide. From 2011 to 2015, 1633 injuries occurred as a result of a slide. The total number of days missed per season was 4263. Surgical intervention was required for 134 (8.2%) injuries, and the mean days missed was 66.5 for players treated surgically and 12.3 days for players treated nonoperatively ( P < .001). MLB players were more likely than MiLB players to require surgical intervention (12.3% vs 7.5%, P = .019). Injuries to the hands/fingers represented 25.3% of all injuries and 31.3% of those requiring surgery. Although the majority of injuries occurred at second base (57%), the per-slide injury rate was similar across all bases ( P = .991). The estimated overall frequency of injury in MLB was once per every 336 slides, and the rate of injury for head- and feet-first slides was 1 in 249 and 413 slides, respectively ( P = .119). Injuries occurring while sliding in professional baseball result in a significant amount of time out of play for these elite athletes

The purpose of this study was to provide new insight into the etiology of primarily nonfatal, work-related electrical injuries. We developed a multistage, case-selection algorithm to identify electrical-related injuries from workers' compensation claims and a customized coding taxonomy to identify pre-injury circumstances. Workers' compensation claims routinely collected over a 1-year period from a large U.S. insurance provider were used to identify electrical-related injuries using an algorithm that evaluated: coded injury cause information, nature of injury, "accident" description, and injury description narratives. Concurrently, a customized coding taxonomy for these narratives was developed to abstract the activity, source, initiating process, mechanism, vector, and voltage. Among the 586,567 reported claims during 2002, electrical-related injuries accounted for 1283 (0.22%) of nonfatal claims and 15 fatalities (1.2% of electrical). Most (72.3%) were male, average age of 36, working in services (33.4%), manufacturing (24.7%), retail trade (17.3%), and construction (7.2%). Body part(s) injured most often were the hands, fingers, or wrist (34.9%); multiple body parts/systems (25.0%); lower/upper arm; elbow; shoulder, and upper extremities (19.2%). The leading activities were conducting manual tasks (55.1%); working with machinery, appliances, or equipment; working with electrical wire; and operating powered or nonpowered hand tools. Primary injury sources were appliances and office equipment (24.4%); wires, cables/cords (18.0%); machines and other equipment (11.8%); fixtures, bulbs, and switches (10.4%); and lightning (4.3%). No vector was identified in 85% of cases. and the work process was initiated by others in less than 1% of cases. Injury narratives provide valuable information to overcome some of the limitations of precoded data, more specially for identifying additional injury cases and in supplementing traditional epidemiologic data for further

Recently injury has become a major world-wide health problem. But studies in Korea about injuries were very few. Thus, this study was conducted to analyze the trend of major injuries from 1991 to 2006 and to provide basic data for preventing injuries. This study was based on the National Statistical Office data from 1991 to 2006 and calculated to estimate the burden of major injuries by using the standard expected years of life lost (SEYLL) and total lost earnings equation. For transport accidents, mortality, SEYLL and total lost earnings were increased from 1991 to 1996 and decreased from 2000 to 2006. On the other hand, for suicides, these were increased gradually. Since 2003, falls were included in ten leading causes of death. This study showed that injury causes major social and economical losses. We could reduce injury related premature death through active interest in injury prevention program.

Several scoring systems for measuring brain injury severity have been developed to standardize the classification of MRI results, which allows for the prediction of functional outcomes to help plan effective interventions for children with cerebral palsy. The aim of this study is to use statistical techniques to optimize the clinical utility of a recently proposed template-based scoring method by weighting individual anatomical scores of injury, while maintaining its simplicity by retaining only a subset of scored anatomical regions. Seventy-six children with unilateral cerebral palsy were evaluated in terms of upper limb motor function using the Assisting Hand Assessment measure and injuries visible on MRI using a semiquantitative approach. This cohort included 52 children with periventricular white matter injury and 24 with cortical and deep gray matter injuries. A subset of the template-derived cerebral regions was selected using a data-driven region selection algorithm. Linear regression was performed using this subset, with interaction effects excluded. Linear regression improved multiple correlations between MRI-based and Assisting Hand Assessment scores for both periventricular white matter (R squared increased to 0.45 from 0, P < 0.0001) and cortical and deep gray matter (0.84 from 0.44, P < 0.0001) cohorts. In both cohorts, the data-driven approach retained fewer than 8 of the 40 template-derived anatomical regions. The equal or better prediction of the clinically meaningful Assisting Hand Assessment measure using fewer anatomical regions highlights the potential of these developments to enable enhanced quantification of injury and prediction of patient motor outcome, while maintaining the clinical expediency of the scoring approach.

To learn more about the causes of nonfatal construction worker injuries, and to identify injury cases for further work-site investigations or prevention programs, an emergency department-based surveillance program was established. Construction workers with work-related injuries or illnesses were identified by reviewing the medical records of all patients treated at the George Washington University Emergency Department between November 1, 1990 and November 31, 1992. Information regarding the worker, the injury, and the injury circumstances were abstracted from medical records. Information was obtained on 592 injured construction workers from numerous trades. Lacerations were the most commonly treated injuries among these workers, followed by strains and sprains, contusions, and eye injuries. Injuries were most commonly caused by sharp objects (n = 155, 26%), falls (n = 106, 18%), and falling objects (n = 70, 12%). Thirty-five percent of injuries were to the hands, wrists, or fingers. Among the twenty-eight injuries severe enough to require hospital admission, eighteen (64%) were caused by falls. Laborers and Hispanic workers were overrepresented among these severe cases. Emergency Department records were a useful surveillance tool for the initial identification and description of work-related injuries. Although E codes were not that useful for formulating prevention strategies, detailed review of injury circumstances from Emergency Department records was valuable and has helped to establish priorities for prevention activities.

The purpose of this review was to identify the relative impact of injected material, location of injury, time to debridement, injection pressure, infection, and the use of adjuvant steroid medication upon the need for amputation after high-pressure injection injuries to the upper extremity. A Medline literature search extending from 1966 to December 2003 was performed, referencing the key words "high-pressure injection injury," "grease gun injury," "paint gun injury," "pressure gun injury," and "high-pressure injection." The results were limited to the English language and to reports involving human subjects. Each abstract was reviewed to confirm that the described injury had occurred in the upper extremity and that it had truly been a high-pressure injection. The reference pages from each of the papers were reviewed to identify additional reports of high-pressure injection injury. Manuscripts describing injuries resulting from hand held syringes or other low-pressure mechanisms were excluded. All of the manuscripts were analyzed to identify the clinical outcome, age, hand dominance, site of injection, substance injected, injection pressure, elapsed time to wide debridement, use of steroids, and incidence of infection. These variables were subjected to a Pearson chi test to determine their impact upon the need for amputation. Four hundred thirty-five cases of high-pressure injection injury to the upper extremity were identified. The amputation rate after these injuries was 30%. The location of the injury and the material injected contributed significantly to the need for amputation. For injections of paint, paint thinner, gasoline, oil, or jet fuel (organic solvents), the amputation risk was lower if wide surgical debridement occurred within 6 hours of injury. Steroids did not impact the amputation rate or incidence of infection. The presence of infection did not affect the incidence of amputation. The risk of amputation after high-pressure injection injury to the

Pneumatic nail guns greatly increase worker productivity and are extensively used in wood frame building construction, with especially high use in residential construction. One surveillance report of nail gun injuries in Washington State has been published; however, other literature consists largely of case reports and case series in trauma journals. The major objective of the current study was to investigate the occurrence of nail gun-associated injuries among construction workers and to identify preventable work-related factors associated with these injuries. Nail gun-related injuries occurring among a cohort of 13,347 carpenters in Ohio who worked union hours during the time period January 1, 1994, until September 30, 1997, were identified by matching the cohort with workers' compensation claims made to the Ohio Bureau of Workers' Compensation. We also analyzed workers' compensation claims for North Carolina Home Builders Association members for the period July 1996-November 1999 to identify nail gun-related injuries. Analyses included stratified analyses of claims by nature and body part injured, calculation of nail gun injury rates, and analyses of free text descriptions of injuries. Overall, nail gun injuries were responsible for 3.9 percent of workers' compensation claims with 8.3 percent to 25.5 percent of claims involving paid lost work time. The overall rate of nail gun injuries (cases per 200,000 work hours) was 0.33 in North Carolina and 0.26 in Ohio, reflecting the greater concentration of wood frame construction workers in the North Carolina population studied. Higher rates of injury were observed for carpenters in North Carolina and among residential carpenters in Ohio. The predominant body part injured was the hands/fingers, with 80 to 89 percent of injuries being nail punctures. Analyses of free text information for puncture injuries found approximately 70 percent of injuries to occur during the framing/sheathing stage of construction. Our data

The increasing popularity of the Wii video game console has been associated with a number of gameplay related traumas. We sought to investigate if there were any identifiable injury patterns associated with Wii use. Utilising a database of self-reported Wii related injuries, the data was categorised by type of injury and game title being played at the time of injury. We found that of 39 reported Wii related injuries over a two-year span, 46% occurred while playing the Wii Sports Tennis software. Further, we identified 14 distinct injury patterns sustained during gameplay. Of these injuries, hand lacerations were the most common, accounting for 44% of the total number of reported cases. Injury associated with video game play is not unique to the Wii, nor is it a new phenomenon. However, the Wii console appears to have a higher rate of associated injuries than traditional game consoles because of its unique user interface. We review the literature and discuss some of the medical complications associated with the Wii and other video game consoles.

We report a prospective study on 284 digital fractures of the hand in 235 patients. Management followed clear guidelines set out in a protocol. Important factors in the selection of the treatment method were, acceptable alignment, functional stability, and associated "significant" soft tissue injuries. "Functionally" stable fractures treated by free mobilization had satisfactory results. Unstable fractures treated by splints or Kirschner wire fixation produced unsatisfactory results. "Open fracture," "comminuted fracture," and "associated significant soft tissue injuries" were identified as unfavorable prognostic factors. The anatomic site of the fractures was not important in determining the final outcome. About 15% of the displaced fractures became functionally stable after closed reduction and their results were comparable with the undisplaced fractures. About 30% of the patients had various degrees of difficulty after they returned to work. About 14% of the patients eventually changed their jobs because of their residual disability.

This study aims to compare hand-rim and power-assisted hand-rim propulsion on potential risk factors for shoulder overuse injuries: intensity and repetition of shoulder loading and force generation in the extremes of shoulder motion. Eleven experienced hand-rim wheelchair users propelled an instrumented wheelchair on a treadmill while upper-extremity kinematic, kinetic and surface electromyographical data was collected during propulsion with and without power-assist. As a result during power-assisted propulsion the peak resultant force exerted at the hand-rim decreased and was performed with significantly less abduction and internal rotation at the shoulder. At shoulder level the anterior directed force and internal rotation and flexion moments decreased significantly. In addition, posterior and the minimal inferior directed forces and the external rotation moment significantly increased. The stroke angle decreased significantly, as did maximum shoulder flexion, extension, abduction and internal rotation. Stroke-frequency significantly increased. Muscle activation in the anterior deltoid and pectoralis major also decreased significantly. In conclusion, compared to hand-rim propulsion power-assisted propulsion seems effective in reducing potential risk factors of overuse injuries with the highest gain on decreased range of motion of the shoulder joint, lower peak propulsion force on the rim and reduced muscle activity.

Tiwari, V K; Sharma, D

1999-09-01

A retrospective study was conducted to evaluate the cause of a sudden rise in number of pediatric admissions with electrical injuries at our centre during the year 1998. In evaluating the cause, six out of twelve admissions were found to be related to kite-flying which is a popular sport during the months of June, July, August and September. In two out of six cases current travelled directly through the string of the kite. In two others, flame burns occured following ignition of clothing. Another patient had contact with wire through a metal rod. In the last case, arcing pulled the hand of the patient leading to direct contact with wire. The average burns size was approximately 31% body surface area (BSA), with all patients having burns over the palmar aspect of at least one hand. No patient required amputation for the injuries. In this article, attention has been focussed on the various modes of electrical injuries associated with kite-flying and some measures have been advised to avoid such accidents.

Recent studies have raised the possibility of a predisposition to mononeuropathies in a number of professions including musicians, cleaners, and industrial workers. There are, however, no previous reports of increased rates of mononeuropathies in the culinary arts. The authors report three cases of mononeuropathies occurring in professional chefs that presented over a 3-month period in the same outpatient clinic, with a case each of distal ulnar neuropathy, distal median motor neuropathy (thenar motor syndrome) and posterior interosseous neuropathy. There was no history of direct hand trauma in any of the patients. In all three patients, the injuries occurred exclusively in the dominant hand, further strengthening the argument for an occupational link.

PLAY HANDS PROTECTIVE GLOVES: TECHNICAL NOTE ON DESIGN AND CONCEPT.

Cerebral Palsy (CP) is the leading cause of childhood motor disability, with a global incidence of 1.6 to 2.5/1,000 live births. Approximately 23% of children with CP are dependent upon assistive technologies. Some children with developmental disabilities have self-injurious behaviors such as finger biting but also have therapeutic needs. The purpose of this technical note is to describe design considerations for a protective glove and finger covering that maintains finger dexterity for children who exhibit finger and hand chewing (dermatophagia) and require therapeutic range of motion and may benefit from sensory stimulation resulting from constant contact between glove and skin. Protecting Little and Adolescent Youth (PLAY) Hands are protective gloves for children with developmental disorders such as CP who injure themselves by biting their hands due to pain or sensory issues. PLAY Hands will be cosmetically appealing gloves that provide therapeutic warmth, tactile sensory feedback, range of motion for donning/ doffing, and protection to maximize function and quality of life for families of children with developmental disorders. The technology is either a per-finger protective orthosis or an entire glove solution designed from durable 3D-printed biodegradable/bioabsorbable materials such as thermoplastics. PLAY Hands represent a series of protective hand wear interventions in the areas of self-mutilating behavior, kinematics, and sensation. They will be made available in a range of protective iterations from single- or multi-digit finger orthoses to a basic glove design to a more structurally robust and protective iteration. To improve the quality of life for patients and caregivers, they are conceptualized to be cosmetically appealing, protective, and therapeutic.

The hand function for persons with cervical spinal cord injury (PCSCI) is most frequently cause difficulties in leading normal lives. The purpose of this study was to test the usability of a new writing assistive device (NWAD) for PCSCI. To access its usability, the authors design usability testing method and test the NWAD to five individuals with cervical spinal cord injury. From the usability testing, we have found number of issues that lead us to key design concept about developing the NWAD. The NWAD will be redesigned based on the result of the present study. We expect that the NWAD will help PCSCI use their affected hand better and improve the level of independence and quality of life.

The characteristics and incidence of injuries at the Summer Paralympic Games have not previously been reported. A better understanding of injuries improves the medical care of athletes and informs future injury prevention strategies. The objective of this prospective cohort study was to characterise the incidence and nature of injuries during the London 2012 Summer Paralympic Games. Injury information was obtained from two databases. One database was populated from medical encounter forms completed by providers at the time of assessment in one of the medical stations operated by the Organising Committee. The second database was populated daily with information provided by team medical personnel who completed a comprehensive, web-based injury survey. The overall injury incidence rate was 12.7 injuries/1000 athlete-days. Injury rates were similar in male and female athletes. The precompetition injury rates in women were higher than those in the competition period. Higher injury rates were found in older athletes and certain sports such as football 5-a-side (22.4 injuries/1000 athlete-days). Overall, 51.5% of injuries were new onset acute traumatic injuries. The most commonly injured region (percentage of all injuries) was the shoulder (17.7%), followed by the wrist/hand (11.4%), elbow (8.8%) and knee (7.9%). This is the largest and most comprehensive epidemiological report examining injuries in Paralympic athletes. Injury rates differ according to age and sport. Upper limb injuries are common. The knowledge gained from this study will inform future injury surveillance studies and the development of prevention strategies in Paralympic sport.

Rodents are the primary animal model of corticospinal injury and repair, yet current behavioral tests do not show the large deficits after injury observed in humans. Forearm supination is critical for hand function and is highly impaired by corticospinal injury in both humans and rats. Current tests of rodent forelimb function do not measure this movement. To determine if quantification of forelimb supination in rats reveals large-scale functional loss and partial recovery after corticospinal injury. We developed a knob supination device that quantifies supination using automated and objective methods. Rats in a reaching box have to grasp and turn a knob in supination in order to receive a food reward. Performance on this task and the single pellet reaching task were measured before and after 2 manipulations of the pyramidal tract: a cut lesion of 1 pyramid and inactivation of motor cortex using 2 different drug doses. A cut lesion of the corticospinal tract produced a large deficit in supination. In contrast, there was no change in pellet retrieval success. Supination function recovered partially over 6 weeks after injury, and a large deficit remained. Motor cortex inactivation produced a dose-dependent loss of knob supination; the effect on pellet reaching was more subtle. The knob supination task reveals in rodents 3 signature hand function changes observed in humans with corticospinal injury: (1) large-scale loss with injury, (2) partial recovery in the weeks after injury, and (3) loss proportional to degree of dysfunction.

Dog bites are common injuries in children. The effects of such injuries can be devastating for the children concerned and their families. It is therefore important to provide holistic care and to consider psychological well-being as well as physical recovery. There should be clear guidelines for professionals about reporting dog bites and safeguarding. The literature recommends primary closure of the dog bite wound unless an infection is present. Literature also suggests that prophylactic antibiotics are ineffective in preventing infection except in hand injuries, although they are still routinely used in practice. This article recommends further research, support and education on dog bites in children, as well as national guidelines.

Homer's Iliad remains a fascinating source of medical history. This epic poem, compiled around 800 BCE, describes several weeks of the last year of the 10-year siege of Troy (Ilion) by the Achaeans. Homer composed the epic by combining and formalizing oral poems, legends, customs, and experiences that originated in the later Mycenaean age (1600-1100 bce). The story centers on the rage of the great warrior Achilles. The Iliad remains the oldest record of Greek medicine and a unique source of surgical history. This study examines the upper extremity injuries described in the Iliad and compares them to those other sites of injury. Copyright © 2013 American Society for Surgery of the Hand.

Boxing injuries can have serious consequences. To examine the epidemiology of boxing injuries in the U.S. with attention to head injuries and children. National estimates of boxing injuries were calculated using data from the National Electronic Injury Surveillance System. Injury rates per 1000 participants for the year 2003 were calculated using boxing participation data. Data analysis was conducted in 2009-2010. An estimated 165,602 individuals (95% CI=134891, 196313) sustained boxing injuries that resulted in a visit to a U.S. hospital emergency department from 1990 through 2008. An average of 8716 (95% CI=7078, 10354) injuries occurred annually, and there was a statistically significant increase in the annual number of injuries during the 19-year study period (slope=610, p<0.001). The rate of injury was 12.7 per 1000 participants. Those injured were predominately male (90.9%). The most common diagnosis was fracture (27.5%), and the most common body regions injured were the hand (33.0%) and head and neck (22.5%). Punching bag-related injuries accounted for 36.8% of boxing injuries. The percentage of injuries that were concussions/closed head injuries in the group aged 12-17 years (8.9%) was similar to that in the group aged 18-24 years (8.1%) and the group aged 25-34 years (8.5%). These findings, based on a nationally representative sample, indicate that injuries related to boxing are increasing in number. Increased efforts are needed to prevent boxing injuries.

Fishing is a leisure activity for some people around the world. Accidently the fish hook can get hooked in the hand. If the hook is barbed, removal becomes difficult. We report a case of such a injury in the hand and discuss the technique for its removal with a brief review of the literature. A thirty-two year old male accidently suffered a fishhook injury to his hand. He came to the orthopaedic ward two hours after the incident with pain; the fish hook was hanging from the hand. Unsuccessful attempts to remove it were made by his relatives. A push-through and cut-off technique was used for removal of barbed hook. Barbed hooks are to be removed atraumatically with controlled incision over properly anaesthetised skin. Proper wound management and prophylactic antibiotics suitable for treatment of Aeromonas species should be initiated to prevent complications.

Injury in China: a systematic review of injury surveillance studies conducted in Chinese hospital emergency departments

PubMed Central

2011-01-01

Background Injuries represent a significant and growing public health concern in China. This Review was conducted to document the characteristics of injured patients presenting to the emergency department of Chinese hospitals and to assess of the nature of information collected and reported in published surveillance studies. Methods A systematic search of MEDLINE and China Academic Journals supplemented with a hand search of journals was performed. Studies published in the period 1997 to 2007 were included and research published in Chinese was the focus. Search terms included emergency, injury, medical care. Results Of the 268 studies identified, 13 were injury surveillance studies set in the emergency department. Nine were collaborative studies of which eight were prospective studies. Of the five single centre studies only one was of a prospective design. Transport, falls and industrial injuries were common mechanisms of injury. Study strengths were large patient sample sizes and for the collaborative studies a large number of participating hospitals. There was however limited use of internationally recognised injury classification and severity coding indices. Conclusion Despite the limited number of studies identified, the scope of each highlights the willingness and the capacity to conduct surveillance studies in the emergency department. This Review highlights the need for the adoption of standardized injury coding indices in the collection and reporting of patient health data. While high level injury surveillance systems focus on population-based priority setting, this Review demonstrates the need to establish an internationally comparable trauma registry that would permit monitoring of the trauma system and would by extension facilitate the optimal care of the injured patient through the development of informed quality assurance programs and the implementation of evidence-based health policy.

Objective: To investigate the features of peripheral nerve injuries in workers exposed to vibration. Methods: A total of 197 male workers [median age: 34 years (21 - 50 years) ; median working years of vibration exposure: 7.3 years (1 - 20 years) ] engaged in grinding in an enterprise were enrolled. Their clinical data and electromyography results were analyzed to investigate the features of peripheral nerve impairment. Results: Of all workers, 96 (48.73%) had abnormal electromyography results. Of all workers, 88 (44.7%) had simple mild median nerve injury in the wrist, who accounted for 91.7% (88/96) of all workers with abnormal electromy-ography results. Six workers had ulnar nerve injury, superficial radial nerve injury, or/and superficial peroneal nerve injury and accounted for 6.3% of all workers with abnormal electromyography results. Of all workers, 88 had a reduced amplitude of median nerve sensory transduction, and 28 had slowed median nerve sensory transduction. A total of 46 workers were diagnosed with occupational hand-arm vibration disease and hospitalized for treatment. They were followed up for more than 4 months after leaving their jobs, and most of them showed improvements in neural electromyography results and returned to a normal state. Conclusion: Workers exposed to vibration have a high incidence rate of nerve injury in the hand, mainly sensory function impairment at the distal end of the median nerve, and all injuries are mild peripheral nerve injuries. After leaving the vibration job and being treated, most workers can achieve improvements and return to a normal state.

This study describes the occurrence of work-related injuries from thermal-, electrical- and chemical-burns among electric utility workers. We describe injury trends by occupation, body part injured, age, sex, and circumstances surrounding the injury. This analysis includes all thermal, electric, and chemical injuries included in the Electric Power Research Institute (EPRI) Occupational Health and Safety Database (OHSD). There were a total of 872 thermal burn and electric shock injuries representing 3.7% of all injuries, but accounting for nearly 13% of all medical claim costs, second only to the medical costs associated with sprain- and strain-related injuries (38% of all injuries). The majority of burns involved less than 1 day off of work. The head, hands, and other upper extremities were the body parts most frequently injured by burns or electric shocks. For this industry, electric-related burns accounted for the largest percentage of burn injuries, 399 injuries (45.8%), followed by thermal/heat burns, 345 injuries (39.6%), and chemical burns, 51 injuries (5.8%). These injuries also represented a disproportionate number of fatalities; of the 24 deaths recorded in the database, contact with electric current or with temperature extremes was the source of seven of the fatalities. High-risk occupations included welders, line workers, electricians, meter readers, mechanics, maintenance workers, and plant and equipment operators.

Mining is a hazardous occupation with elevated rates of lost-time injury and disability. The purpose of this study is twofold: 1) To identify the type of lost-time injuries in the mining workforce, regardless of the kind of mining and 2) To examine the antecedent factors to the occupational injury (lost-time injuries). We identified and extracted primary papers related to lost-time injuries in the mining sector by conducting a systematic search of the electronic literature in the eight health and related databases. We critically reviewed nine articles in the mining sector that examined lost-time injuries. Musculoskeletal injuries (hand, back, limbs, fractures, lacerations and muscle contusions), slips and falls were identified as types of lost-time injuries. The review identified the following antecedent factors related to lost-time injuries: the mining work environment (underground mining), being male, age, working with mining equipment, organizational size, falling objects, disease status, job training and lack of occupational safety management teams, recovery time, social supports, access to health services, pre-injury health status and susceptibility to injury. The mining sector is a hazardous environment that increases workers' susceptibility to occupational injuries. There is a need to create and implement monitoring systems of lost-time injuries to implement prevention programs.

Case series. Hand injuries are the most common injury observed in hurling although compliance in wearing protective gloves is reportedly low. To devise a glove that offers comfort, protection and freedom of movement, using the bespoke capabilities of 3-dimensional (3D) printing. Each player's "catching" hand was imaged using a 3D scanner to produce a bespoke glove that they later trialed and provided feedback. Nine players provided feedback. On average, the players favorably rated the glove for the protection offered. The average response on comfort was poor, and no players reported that glove aided performance during play. This feasibility study explores the versatility of 3D printing as a potential avenue to improve player compliance in wearing protective sportswear. Feedback will help refine glove design for future prototypes. Hurling is the primary focus in this study, but knowledge gains should be transferable to other sports that have a high incidence of hand injury. 4. Crown Copyright © 2017. Published by Elsevier Inc.

Sears, Erika Davis; Larson, Bradley P; Chung, Kevin C

2013-03-01

The authors' aim was to conduct a national survey of hand surgery fellowship program directors to determine differences of opinions of essential components of hand surgery training between program directors from plastic and orthopedic surgery programs. The authors performed a Web-based survey of 74 program directors from all Accreditation Council for Graduate Medical Education-accredited hand surgery fellowship programs to determine components that are essential for hand surgery training. The survey included assessment of nine general areas of practice, 97 knowledge topics, and 172 procedures. Twenty-seven scales of related survey items were created to determine differences between specialty groups based on clinical themes. An 84 percent response rate was achieved, including 49 orthopedic and 12 plastic surgery program directors. There were significant differences in mean responses between the specialty groups in 11 of 27 scales. Only one scale, forearm fractures, contained items with a significantly stronger preference for essential rating among orthopedic surgeons. The other 10 scales contained items with a significantly higher preference for essential rating among plastic surgeons, most of which related to soft-tissue injury and reconstruction. The burn scale had the greatest discrepancy in opinion of essential ratings between the groups, followed by pedicled and free tissue transfer, and amputation and fingertip injuries. Despite being united under the subspecialty of hand surgery, program directors tend to emphasize clinical areas that are stressed in their respective primary disciplines. These differences promote the advantage of programs that provide exposure to both plastic surgery-trained and orthopedic surgery-trained hand surgeons.

Background: In literature, the competitive sport of modern karate is almost always characterised as a combat sport involving injuries caused by impact effects and physical contact with opponents. There is a lack of data regarding the outcome after karate injuries, specifically with a view to the contact-free Kata karate. Methods: Performing a random test using a questionnaire, we collected data concerning regular medical treatment, prior surgeries of the locomotor system, and medical care. This study included 300 athletes from 65 countries (average age: 24.1 years; 176 male, 124 female) participating in the Karate World Cup 2014. Seven participants competed in both disciplines, 87 only in the Kata discipline, and 206 only in Kumite (the discipline involving physical contact with opponents). The statistical analysis was performed using a two-sided Chi-square test and the Fisher's exact test. Results : Recurrent medical treatment was most commonly required for the knee region (Kata 28.7 %, Kumite 26.7 %). In Kata the shoulder region came second (22.9 %), in Kumite the ankle region (21.8 %), followed by hand and foot in both groups. Medical treatment of the elbow area was more frequent in the Kata Group (p = 0.033), while in Kumite athletes' hand (p = 0.002) and foot injuries (p = 0.007) prevailed. Prior surgeries of athletes of both disciplines most commonly concerned the knee, followed by the ankle region in the Kata group and by the hand and head region in the Kumite group. Statistically significant differences between the two disciplines were found in head injuries (p = 0.004), which commonly do not occur in the Kata discipline. During the World Cup, 56.0 % of the athletes had no individual medical care and 24.6 % received no sports-related medical care in their home countries. Conclusion: Although the risk of injuries in Kumite Karate has been reduced by the introduction of gumshields, hand and foot protectors as well as a reform of

To measure the desirable health outcome, termed utility, and the expected quality-adjusted life years (QALYs) gained with hand composite tissue allotransplantation (CTA) using hand amputee patients and the general public. Using the standard gamble (SG) and time trade-off (TTO) techniques, utilities were obtained from 30 general public participants and 12 amputee patients. The health utility and net QALYs gained or lost with transplantation were computed. A sensitivity analysis was conducted to account for the effects of lifelong immunosuppression on the life expectancy of transplant recipients. Higher scores represent greater utility. Hand amputation mean health utility as measured by the SG and TTO methods, respectively, was 0.72 and 0.80 for the general public and 0.69 and 0.70 for hand amputees. In comparison, hand CTA mean health utility was 0.74 and 0.82 for the general public and 0.83 and 0.86 for amputees. Hand CTA imparted an expected gain of 0.9 QALYs (SG and TTO) in the general public and 7.0 (TTO) and 7.8 (SG) QALYs in hand amputees. A loss of at least 1.7 QALYs was demonstrated when decreasing the life expectancy in the sensitivity analysis in the hand amputee group. Hand amputee patients did not show a preference toward hand CTA with its inherent risks. With this procedure being increasingly adopted worldwide, the benefits must be carefully weighed against the risks of lifelong immunosuppressive therapy. This study does not show clear benefit to advocate hand CTA. Copyright © 2015 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.

Table saw injuries: epidemiology and a proposal for preventive measures.

PubMed

Chung, Kevin C; Shauver, Melissa J

2013-11-01

Table saws are ubiquitous devices in professional, home, and school woodshops that have the potential to cause severe injuries. Many of these injuries results in finger and thumb tendon, nerve, and vascular damage or amputation. Long-term outcomes of these injuries can include functional and sensory deficits. Table saw manufacturers are required to equip saws with blade guards to prevent blade contact; nevertheless, treatment of table saw injuries is a common occurrence in U.S. emergency departments. The authors performed a literature search using PubMed and the Cumulative Index to Nursing and Allied Health Literature to compile epidemiology data relevant to table saw injuries. The authors also reviewed the U.S. Consumer Product Safety Commission's briefing package on table saw blade contact injuries. Over 30,000 table saw injuries occur annually. Fingers and hands are the most frequently injured body parts, and lacerations are the most common injuries. Individuals suffering from occupational injuries tend to be younger than those injured during amateur woodworking. A small but important minority of injuries are to students participating in school shop classes. Medical costs for the treatment of table saw injuries are estimated at more than $2 billion every year. SawStop technology stops the saw blade when contact with skin is made, resulting in a small cut rather than a more complicated laceration or amputation. The application of this novel technology in saw designs can prevent serious injuries that deleteriously affect lives at the personal and societal levels.

Our objective for this study was to describe the epidemiology of lawn mower-related injuries among children in the United States. A retrospective analysis was conducted of data from children who were 20 years and younger in the National Electronic Injury Surveillance System of the United States Consumer Product Safety Commission for 1990-2004. There were an estimated 140700 lawn mower-related injuries to children who were 20 years and younger and treated in hospital emergency departments in the United States during the 15-year period of 1990-2004. This yielded an average of 9400 injuries annually, or 11.1 injuries per 100000 US children per year. The mean age was 10.7 (SD: 6.0) years, and 78% were boys. The leading type of lawn mower-related injury sustained by patients was a laceration (41.2%), followed by soft tissue injury (21.4%), burn (15.5%), and fracture (10.3%). The most common body region injured was the hand/finger (34.6%), followed by lower extremity (18.9%) and foot/toe (17.7%). The eyeball/face and upper extremity accounted for 10.6% and 7.4% of injuries, respectively. Burns accounted for 34.5% of injuries to the hand/finger compared with 5.5% to other body regions. Ninety-seven percent of amputation injuries occurred to the foot/toe (49.5%) and hand/finger (47.5%) compared with 3% of amputations to other body regions. Burns accounted for 41.8% of injuries among children who were < or = 5 years of age compared with 6.5% of injuries to children who were older than 5 years. Foreign body injuries accounted for 4.8% of injuries among children who were > or = 12 years of age compared with 1.6% of injuries to children who were younger than 12 years. Amputations (31.9%), lacerations (28.8%), and fractures (26.0%) accounted for almost 87% of injuries among children who were admitted or transferred to another hospital. In contrast, lacerations (42.3%), soft tissue injuries (23.3%), and burns (16.9%) predominated among children who were treated and released to

Penetrating injuries of the aorta are rare and highly lethal; very few patients are able to reach the hospital alive. We report a case of penetrating injury into the ascending aorta with the arrow still in situ, shot by a bow in a tribal region of India. The wound of entry into the aorta was sealed by the arrow itself. The patient came to us walking and supporting the arrow with his left hand. He was operated on, and the arrow was successfully removed from the aorta. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Softball is a popular participant sport in the United States. This study investigated the epidemiology of softball injuries with comparisons between children and adults. Data from the National Electronic Injury Surveillance System for patients 7 years and older treated in an emergency department (ED) for a softball injury from 1994 through 2010 were analyzed. An estimated 2107823 (95% confidence interval [CI], 1736417-2479229) patients were treated in US EDs for a softball injury during the 17-year study period. The annual number of injuries decreased by 23.0% from 1994 to 2010 (P < .001); however, during the last 6 years of the study, injuries increased by 11.7% (P = .008). The annual rate of softball injuries increased significantly during the study period (P = .035). The most commonly injured body regions were the hand/wrist (22.2%) and face (19.3%). Being hit by a ball was the most common mechanism of injury (52.4%) and accounted for most of face (89.6%) and head (75.7%) injuries. Injuries associated with running (relative risk, 2.36; 95% CI, 1.97-2.82) and diving for a ball (relative risk, 4.61; 95% CI, 3.50-6.09) were more likely to occur among adult than pediatric patients. To our knowledge, this is the first study to investigate softball injuries using a nationally representative sample. Softball is a common source of injury among children and adults. Increased efforts are needed to promote safety measures, such as face guards, mouth guards, safety softballs, and break-away bases, to decrease these injuries. Copyright © 2013 Elsevier Inc.

[Hand osteoarthritis].

PubMed

Šenolt, Ladislav

Hand osteoarthritis (OA) is a common chronic disorder causing pain and limitation of mobility of affected joints. The prevalence of hand OA increases with age and more often affects females. Clinical signs obviously do not correlate with radiographic findings - symptomatic hand OA affects approximately 26 % of adult subjects, but radiographic changes can be found in up to two thirds of females and half of males older than 55 years.Disease course differ among individual patients. Hand OA is a heterogeneous disease. Nodal hand OA is the most common subtype affecting interphalangeal joints, thumb base OA affects first carpometacarpal joint. Erosive OA represents a specific subtype of hand OA, which is associated with joint inflammation, more pain, functional limitation and erosive findings on radiographs.Treatment of OA is limited. Analgesics and nonsteroidal anti-inflammatory drugs are the only agents reducing symptoms. New insights into the pathogenesis of disease should contribute to the development of novel effective treatment of hand OA.

The popularity of bicycle riding for recreation, exercise and transportation has grown enormously in recent years, which has led to an increased incidence of bicycle-related injuries. While these injuries involve mainly the musculoskeletal system, data on shoulder-specific injuries incurred while bike riding are lacking. Classifying these shoulder injuries may provide insight and assistance in the creation and implementation of effective protective gear and measures. To investigate the types and mechanisms of shoulder injuries among cyclists. This study retrospectively examined all cyclists who incurred shoulder injuries while riding and were admitted to the emergency department and shoulder clinic between January 2008 and November 2013. The study included 157 subjects with various bicycle-related shoulder injuries treated with either conservative or surgical measures. Eighty-four percent of injuries were caused by a direct blow to the shoulder, 7% by falling on an outstretched hand, 6% were traction injuries, and 3% were due to hyperabduction. Nine different clinical types of injury were observed; the most common injuries were clavicle fractures (32%), followed by acromioclavicular joint dislocations (22%), rotator cuff tears (22%), and humeral fractures (8%). Fifty-one percent of subjects were managed with conservative care and the remaining patients required surgical interventions. Shoulder injuries incurred while riding a bicycle span the entire spectrum of shoulder injuries and often result in debilitating conditions. Although the use of helmets is increasing, there is currently no effective protective gear or measures to prevent riders from suffering shoulder injuries.

2007-09-01

A series of 15 consecutive patients with various hand defects requiring flap coverage was reviewed in this study. The defects were all covered with the distally based posterior interosseous flap. Its main indications were in complex hand trauma, severe burn injury, or skin cancer ablation, either acute or postprimary. In 12 of the patients, flaps survived completely. In 3 patients, there was partial necrosis of the distal part of the flap, which did not require additional surgical procedure. Radial nerve palsy was noted in one of the cases, with a complete recovery after 3 months. Donor site was closed directly in up to 4-cm-wide flaps, while larger flaps required skin grafting. No major anatomic variation was observed. Distally based posterior interosseous flap is a reliable choice for various types and areas of hand defects, with very low donor-site morbidity, and should be more commonly considered in clinical practice.

Prognostic Determinants in Patients with Traumatic Pancreatic Injuries

2008-01-01

The aim of this study was to identify factors that predict morbidity and mortality in patients with traumatic pancreatic injuries. A retrospective review was performed on 75 consecutive patients with traumatic pancreatic injuries admitted to the Emergency Medical Center at Masan Samsung Hospital and subsequently underwent laparotomy during the period January 2000 to December 2005. Overall mortality and morbidity rates were 13.3% and 49.3%, respectively. A multivariate regression analysis revealed that greater than 12 blood transfusions and an initial base deficit of less than -11 mM/L were the most important predictors of mortality (p<0.05). On the other hand, the most important predictors of morbidity were surgical complexity and an initial base deficit of less than -5.8 mM/L (p<0.01). These data suggests that early efforts to prevent shock and rapidly control of bleeding are most likely to improve the outcome in patients with traumatic pancreatic injuries. The severity of pancreatic injury per se influenced only morbidity. PMID:18303212

HIV-1 infected individuals are living longer but experiencing a prevalence rate of over 50% for HIV-1 associated neurocognitive disorders (HAND) for which no effective treatment is available. Viral and cellular factors secreted by HIV-1 infected cells leads to neuronal injury and HIV-1 Tat continues to be implicated in the pathogenesis of HAND. Here we tested the hypothesis that creatine protected against HIV-1 Tat-induced neuronal injury by preventing mitochondrial bioenergetic crisis and/or redox catastrophe. Creatine blocked HIV-1 Tat1-72-induced increases in neuron cell death and synaptic area loss. Creatine protected against HIV-1 Tat-induced decreases in ATP. Creatine and creatine plus HIV-1 Tat increased cellular levels of creatine, and creatine plus HIV-1 Tat further decreased ratios of phosphocreatine to creatine observed with creatine or HIV-1 Tat treatments alone. Additionally, creatine protected against HIV-1 Tat-induced mitochondrial hypopolarization and HIV-1 Tat-induced mitochondrial permeability transition pore opening. Thus, creatine may be a useful adjunctive therapy against HAND. PMID:25613139

To describe injury rates and patterns in the emerging sport of hardcourt bike polo (HBP). Descriptive survey. HBP playing areas (urban flat concrete surfaces). Twenty-two adult (≥18 years) HBP players who presented to a routine thrice-weekly playing site completed the survey. Participants completed a survey that was used to evaluate demographics; frequency of play; rate, localization, and severity of injuries sustained in the past 1 year; and use of medical care. The incidence of sustaining an injury in 1 year was 0.86. The main sites of injury involved the knee, elbow, wrist, and hand. Medical attention was sought by 15% of the injured players. HBP is a rapidly evolving urban sport in which participants are at risk for trauma-related injury, some of which may be preventable by the addition of appropriate safety equipment.

Repeated measures design. This study compared the upper extremity (UE) joint kinetics between three transfer techniques. Research laboratory. Twenty individuals with spinal cord injury performed three transfer techniques from their wheelchair to a level tub bench. Two of the techniques involved a head-hips method with leading hand position close (HH-I) and far (HH-A) from the body, and the third technique with the trunk upright (TU) and hand far from body. Motion analysis equipment recorded upper body movements and force sensors recorded their hand and feet reaction forces during the transfers. Several significant differences were found between HH-A and HH-I and TU and HH-I transfers indicating that hand placement was a key factor influencing the UE joint kinetics. Peak resultant hand, elbow, and shoulder joint forces were significantly higher for the HH-A and TU techniques at the trailing arm (P < 0.036) and lower at the leading arm (P < 0.021), compared to the HH-I technique. Always trailing with the same arm if using HH-A or TU could predispose that arm to overuse related pain and injuries. Technique training should focus on initial hand placement close to the body followed by the amount of trunk flexion needed to facilitate movement.

Military service in Finland is compulsory for all male citizens and annually about 80% of 19-year-old men enter into the service. The elevated risk for many chronic diseases and loss of function among those who are inactive and unfit can be often detected already in youth. On the other hand, activity-induced injuries among young are true public health issue. The purpose of the present prospective cohort follow-up study was to evaluate predictive associations between acute or overuse injuries and their various intrinsic risk factors. Four successive cohorts of conscripts who formed a representative sample of Finnish young men were followed for 6 months. At the beginning of the service, the risk factors of injuries were measured and recorded and then the acute and overuse injuries treated at the garrison clinic were identified. Predictive associations between injuries and their risk factors were examined by multivariate Cox's proportional hazard models. Of the 1411 participants, 27% sustained an acute injury and 51% suffered from overuse injury. Concerning acute injuries, highest risk for severe injuries were detected among conscripts with low fitness level in both the standing long-jump and push-up tests (hazard rate, HR=5.9; 95% CI: 1.6‒21.3). A history of good degree in school sports was not a protective factor against acute injuries. High waist circumference and, on the other hand, being underweight according to BMI increased the HR for overuse injuries. Brisk leisure time physical activity before military entry was a protective factor against overuse injuries. Poor result in Cooper's test was a warning signal of elevated risk of overuse injuries. We confirmed previous findings that low level of physical fitness is predictor for musculoskeletal injuries during intensive physical training. The U-shaped relationship between body composition and overuse injuries was noticed indicating that both obesity and underweight are risk factors for overuse injuries. Persons

This study characterizes the epidemiology of nonfatal pediatric firework-related injuries in the United States among children and adolescents by analyzing data from the National Electronic Injury Surveillance System from 1990 through 2014. During this 25-year period, an estimated 136 991 (95% CI = 113 574-160 408) children <20 years old were treated in US emergency departments for firework-related injuries. The annual injury rate decreased significantly by 30.4% during this period. Most of those injured were male (75.7%), mean patient age was 10.6 years, and 7.6% required hospital admission. The hands (30.0%) were the most commonly injured body region, followed by head and neck (22.2%), and eyes (21.5%). Sixty percent of injuries were burns. Injuries were most commonly associated with firecrackers (26.2%), aerial devices (16.3%), and sparklers (14.3%). Consumer fireworks pose a serious injury risk to pediatric users and bystanders, and families should be encouraged to attend public firework displays rather than use consumer fireworks.

Nerve injury following shoulder dislocation: the emergency physician's perspective.

PubMed

Ameh, Victor; Crane, Steve

2006-08-01

We describe the case of a 57-year-old woman who presented to the emergency department with a right anterior shoulder dislocation following a fall onto the right shoulder and right upper arm. She also complained of numbness in the right forearm and dorsum of the right hand. The examination revealed a bruise to the upper aspect of the right arm resulting from the impact following the fall. The patient also had a right wrist drop and loss of sensation in the lateral border of the right forearm and on the dorsum of the right hand, suggesting a radial nerve injury. She also had altered sensation in the ulnar distribution of her right hand, suspicious of concomitant ulnar nerve injury. No loss of sensation in the distribution of the axillary nerve (regimental patch) was observed. These findings were carefully documented and the patient subsequently had the shoulder reduced under entonox and morphine. The neurological deficits remained unchanged. The patient was sent home from the emergency room with arrangements for orthopaedic and physiotherapy follow-up. After a 3-month period, she had clinical and electromyography evidence of persistent radial and ulnar nerve deficit. She continues to have physiotherapy. This case highlights the need for awareness of the potential for nerve damage following shoulder dislocation and also to ensure that appropriate follow-up plan is instituted on discharge from the emergency department.

Various neurological conditions, such as stroke or spinal cord injury, result in an impaired control of the hand. One method of restoring this impairment is through functional electrical stimulation (FES). However, traditional FES techniques often lead to quick fatigue and unnatural ballistic movements. In this study, we sought to explore the capabilities of a non-invasive proximal nerve stimulation technique in eliciting various hand grasp patterns. The ulnar and median nerves proximal to the elbow joint were activated transcutanously using a programmable stimulator, and the resultant finger flexion joint angles were recorded using a motion capture system. The individual finger motions averaged across the three joints were analyzed using a cluster analysis, in order to classify the different hand grasp patterns. With low current intensity (<5 mA and 100 µs pulse width) stimulation, our results show that all of our subjects demonstrated a variety of consistent hand grasp patterns including single finger movement and coordinated multi-finger movements. This study provides initial evidence on the feasibility of a proximal nerve stimulation technique in controlling a variety of finger movements and grasp patterns. Our approach could also be developed into a rehabilitative/assistive tool that can result in flexible movements of the fingers.

During the past 15 years fewer than 1% of those treated in the National Spinal Cord Injury Center were injured as a result of aviation accidents. In addition to 9 such patients treated at the center since 1973, another 6 were found among the many hundreds receiving ambulatory care in our clinics. 3 patients had survived a helicopter crash, 2 were injured while ejecting from combat aircraft, 3 were injured in crashes of light aircraft, 1 fell from a hand glider and 6 were injured in parachute drops. Of the 15 reviewed, 6 use wheelchairs, 3 walk assisted by orthopedic devices, while 6 ambulate freely. Although initial hospitalization was not substantially longer than in other patients with spinal cord injuries, extended ambulatory psychological intervention was necessary.

Context: Golf is a popular sport, particularly in older populations. Regardless of age and skill level, golfers risk injury to the back, shoulder, wrist and hand, elbow, and knee. Because of the unique compressive, shear, rotational, and lateral bending forces created in the lumbar region during the golf swing, the primary sport-related malady experienced by amateurs and professionals is low back pain. Extrinsic and intrinsic injury risk factors have been reported in the literature. A growing body of evidence supports the prescription of strength training routines to enhance performance and reduce the risk of injury. Evidence Acquisition: Relevant studies were reviewed on golf injuries, swing mechanics, training routines, and general training program design. The following electronic databases were used to identify research relevant to this report: MEDLINE (from 1950–November 2009), CINAHL (1982–November 2009), and SPORTDiscus (1830–November 2009). Results: Injuries may be associated with lack of warm-up, poor trunk flexibility and strength, faulty swing technique, and overuse. Conclusions: Implementing a training program that includes flexibility, strength, and power training with correction of faulty swing mechanics will help the golfer reduce the likelihood of injury and improve overall performance.

The fall-related injuries of old people have attracted increasing attention particularly because of the continuous aging of the population. In this meta-analysis, we aim to present the incidence and sub-groups of fall-related injuries among old people in mainland China. A systematic electronic literature search was performed using four Chinese and two English databases. The selected papers were cross-sectional studies in mainland China, the participants of which were recruited based on inclusion and exclusion criteria. Data were collected through face-to-face interviews using questionnaire. The risk of bias was assessed using the Reporting of Observational Studies in Epidemiology (STROBE), and the pooled rates were estimated by DerSimonian and Laird random-effects model. A total of 40 cross-sectional studies that focused on 128,691 participants who were aged 60 years were included in this review. On the one hand, 54.95 per 1000 (overall), 45.94 per 1000 (males), 78.89 per 1000 (females), 25.95 per 1000 (60 years to 69 years), 33.03 per 1000 (70 years to 79 years), and 62.74 per 1000 (≥80 years) were estimated for the pooled incidence of fall-related injury. On the other hand, 91.72 per 1000 (overall), 94.54 per 1000 (males), and 144.93 per 1000 (females) were estimated for person-time incidence of fall-related injury. Higher incidence rates were observed in females compared with males, and these rates continued to increase along with age. A moderate level of fall-related injuries was observed among old people in mainland China. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The International Classification of Functioning, Disability and Health (ICF) provides a standardized language of almost 1500 ICF categories for coding information about functioning and contextual factors. Short lists (ICF Core Sets) are helpful tools to support the implementation of the ICF in clinical routine. In this paper we report on the implementation of ICF Core Sets in clinical routine using the "ICF Core Sets for Hand Conditions" and the "Lighthouse Project Hand" as an example. Based on the ICF categories of the "Brief ICF Core Set for Hand Conditions", the ICF-based assessment tool (ICF Hand A ) was developed aiming to guide the assessment and treatment of patients with injuries and diseases located at the hand. The ICF Hand A facilitates the standardized assessment of functioning - taking into consideration of a holistic view of the patients - along the continuum of care ranging from acute care to rehabilitation and return to work. Reference points for the assessment of the ICF Hand A are determined in treatment guidelines for selected injuries and diseases of the hand along with recommendations for acute treatment and care, procedures and interventions of subsequent treatment and rehabilitation. The assessment of the ICF Hand A according to the defined reference points can be done using electronic clinical assessment tools and allows for an automatic generation of a timely medical report of a patient's functioning. In the future, the ICF Hand A can be used to inform the coding of functioning in ICD-11.
