Electric Scooter-Related Upper Limb Fractures: Analysis of 458 Cases.

PURPOSE: To perform an analysis of electric scooter (e-scooter)-related upper limb fractures (ULFs), which have increased dramatically in parallel with the rapid rise in the use of e-scooters and shared e-scooter services in recent years. METHODS: We retrospectively reviewed the medical charts of e-scooter-related emergency department visits between January 2017 and January 2020 at a level I trauma center. All patients with ULFs were included in the study, and their data were analyzed for demographics, fracture diagnosis, associated injuries, and required surgical treatment. RESULTS: This study included 356 patients (50% men) with 458 ULFs, of which 23 (5%) were open fractures. The mean age of the cohort was 32.9 years (standard deviation, 10.1 years). The most common mechanism of injury was rider fall (92.1%). The nondominant hand was injured in 53.1% of cases, and 32.1% of all fractures were treated with surgery. A total of 120 (33.7%) patients sustained more than 1 ipsilateral ULF, and 27 (7.6%) patients had a concomitant contralateral ULF. Radial head fracture was the most common fracture type (n = 123, 26.8%), of which 16 (13%) were bilateral. The fifth ray was injured most frequently among the metacarpal and phalangeal fractures (n = 33, 47.1%). Most of the nonextremity-associated injuries were those of the head and maxillofacial bones. CONCLUSIONS: The most common ULF associated with e-scooters was the radial head fracture. Physicians should be alert to and seek associated fractures during initial assessments of e-scooter-related upper limb injuries. Further investigation may be warranted to evaluate the effectiveness of protective measures in reducing the number of injuries. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Initial kinematic chain injuries increase hazard of subsequent arm injuries in professional baseball pitchers.

BACKGROUND: Currently, there are few studies that have evaluated the relationship between a lower extremity or trunk injury (kinematic chain) and subsequent arm injury. The purpose of this study was (1) to investigate the relationship between initial kinematic chain (lower extremity or trunk) injury and subsequent arm injury; and (2) to investigate the relationship between initial shoulder or elbow injury and subsequent arm injury. METHODS: A 7-year prospective injury risk study was conducted with Minor League Baseball pitchers. Pitches, pitching appearances, athlete exposures (AEs), and arm injuries (≥1-day time loss) were documented throughout the season. Cox survival analyses with 95% confidence intervals (95% CIs) were performed. Confounders controlled for included age, body mass index, arm dominance, pitching role, previous arm injury, number of pitching appearances, and seasonal pitch load. RESULTS: A total of 297 pitchers participated (total player days = 85,270). Arm injury incidence was 11.4 arm injuries/10,000 AEs, and kinematic chain incidence was 5.2 injuries/10,000 AEs. Pitchers who sustained a kinematic chain injury demonstrated a greater hazard (2.6 [95% CI: 1.2, 5.6], P = .019) of sustaining an arm injury. Pitchers who sustained an initial shoulder injury demonstrated a greater hazard (9.3 [95% CI: 1.1, 83], P = .047) of sustaining a subsequent shoulder or elbow injury compared with pitchers who sustained an initial elbow injury. CONCLUSIONS: Pitchers who sustained an initial lower extremity or trunk injury demonstrated an increased subsequent arm injury hazard compared with pitchers who did not. Pitchers who sustained an initial shoulder injury demonstrated a greater hazard of sustaining a subsequent arm injury compared with pitchers who sustained an initial elbow injury. However, this secondary analysis should be interpreted with caution. Clinicians should monitor risk with workload accumulation, which may be related to pitching compensatory strategies in a fatigued state. Pitchers who sustain a shoulder injury should be evaluated and perform both shoulder and elbow rehabilitation strategies before return to sport.

Acute distal biceps tendon rupture: retrospective analysis of two different approaches and fixation techniques.

PURPOSE: The aim of our study is to compare the modified double incision (DI) with bone tunnel reinsertion with the single-incision (SI) double tension slide technique in terms of clinical and functional outcomes and complication rates. METHODS: A retrospective comparative analysis was performed on 65 patients treated for total distal biceps tendon rupture. The surgical technique adopted for each patient was based on the preference of two experienced elbow surgeons. The DASH and MAYO questionnaires, functional outcome and ROM were recorded in all subjects. RESULTS: Of 65 patients, we collected data of a cohort of 54 distal biceps tendon ruptures that satisfied inclusion criteria. Twenty-five were treated by modified DI and 29 SI techniques. The recovery of the complete ROM in terms of flexion/extension and prono-supination occurred in the 79.6% of the patients, without statistical significant difference between the adopted technique. We reported a complication rate of 12% and 20.7% for DI and SI techniques, respectively, without statistical correlation (P = 0.84). The average DASH score was similar for DI and SI techniques without significant differences (P = 0,848). The Mayo score results were excellent in the majority of the patients. No significant difference in MAYO results was reported comparing the surgical techniques (P = 1). CONCLUSION: Both techniques provide a reliable and strong repair with an optimal recovery of ROM returning to preinjury activity with substantially overlapping timelines.

Surgical Treatment of Upper Extremity Gunshot Injures: An Updated Review.

INTRODUCTION: Firearm morbidity and mortality have been increasing in recent years, and with this, the demand for medical personnel firearm injury treatment knowledge. Extremities contribute to a majority of firearm injuries, with these injuries being particularly complex because of neurovascular proximity within a confined space. Knowledge of firearm mechanism of injury and treatment management options is important for any trauma hand surgeon. Many factors play vital roles in the treatment of complex upper extremity (UE) gunshot wounds (GSWs). The aim of our review and case illustrations is to provide hand surgeons with an up-to-date guide for initial emergent management, soft tissue, bony, and nerve repair and reconstruction. PATIENT AND METHODS: A literature review was conducted in the current management of UE GSW injuries, and 2 specific patient case examples were included. High-energy versus low-energy GSWs were documented and compared, as well as containment injures. Management including soft tissue, bony, and nerve injuries was explored along with patient outcome. Based on these findings, guidelines for GSW management were purposed. CONCLUSION: Gunshot wounds of the UE encompass a group of highly heterogeneous injuries. High-energy wounds are more extensive, and concomitant injuries to bone, vessel, nerve, muscle, and soft tissue are common. Early treatment with adequate debridement, skeletal fixation, and soft tissue coverage is indicated for complex injuries, and antibiotic treatment in the pre-, peri-, and postoperative period is indicated for operative injuries. Soft tissue coverage options include the entire reconstructive ladder, with pattern of injury and considerations of wound characteristics dictating reconstructive choice. There are arguments to using either external or internal bony fixation techniques for bone fracture management, with choice tailored to the patient. For management of nerve injuries, we advocate earlier nerve repair and a shorter duration of observation before secondary reconstruction in selective cases. If transected nerve endings cannot be brought together, nerve autografts of shorter length are recommended to bridge nerve ending gaps. A significant number of patients with GSW fail to make necessary follow-up appointments, which adds to challenges in treatment.

Does humeral torsion play a role in shoulder and elbow injury profiles of overhead athletes: a systematic review.

BACKGROUND: Humeral retrotorsion (HRT) is one bony adaptation that occurs in overhead athletes. This bony adaptation often leads to bilateral changes in range of motion at the glenohumeral joint. Because HRT can create different stress environments on the surrounding tissue, it may play a role in upper-limb injury and pain profiles. Therefore, the aim of this review was to examine whether HRT plays a role in shoulder and elbow injury profiles. METHODS: Two separate critical appraisal tools were administered: the Newcastle-Ottawa Scale (case control) and the Appraisal Tool for Cross-sectional Studies. The primary author extracted all data and obtained means and standard deviations for each outcome. Cohen d effect sizes (ESs) were calculated (ES [95% confidence interval]) for all HRT measurements including nondominant, dominant, and side-to-side differences. Finally, the Strength of Recommendation Taxonomy was used to evaluate the overall strength of the recommendation. RESULTS: Nine articles were included in this review. Large ESs were present in 2 studies on examination of symptomatic and asymptomatic dominant HRT and ranged between 0.83 (0.08-1.55) and -2.57 (-3.66 to 1.99). The majority of all ESs for all HRT measurements were moderate or low, rendering comparisons between asymptomatic and symptomatic cohorts that were not clinically meaningful. CONCLUSION: The Strength of Recommendation Taxonomy rating was C based on inconsistent findings. Differences in sports populations and definitions of injuries across studies may be one reason for the varying ESs. HRT does occur in the overhead population, but the degree to which this HRT starts to affect upper-limb injury is unknown and is more than likely player specific and multifactorial.

Upper extremity disability and quality of life after breast cancer treatment in the Greater Plains Collaborative clinical research network.

PURPOSE: Chronic upper extremity disability (UED) is common after breast cancer treatment but under-identified and under-treated. Although UED has been linked to quality of life (QoL), the role of UED as mediator between contemporary treatment practices and QoL has not been quantified. This investigation describes UED in a contemporary sample of breast cancer patients and examines its relationship with personal and treatment factors and QoL. METHODS: Eight hundred and thirty-three women diagnosed at eight medical institutions during 2013-2014 with microscopically confirmed ductal carcinoma in situ or invasive stage I-III breast cancer were surveyed an average of 22 months after diagnosis. UED was measured with a modified QuickDASH and QoL with the FACT-B. The questionnaire also collected treatments, sociodemographic information, comorbidity, body mass index, and a 3-item health literacy screener. RESULTS: Women who received post-mastectomy radiation and chemotherapy experienced significantly worse UED and QoL. Women who had lower income, lower health literacy and prior diabetes, arthritis or shoulder diagnoses had worse UED. Patients with worse UED reported significantly worse QoL. Income and health literacy were independently associated with QoL after adjustment for UED but treatment and prior conditions were not, indicating mediation by UED. UED mediated 52-79% of the effect of mastectomy-based treatments on QoL as compared with unilateral mastectomy without radiation. UED and QoL did not differ by type of axillary surgery or post-mastectomy reconstruction. CONCLUSIONS: A large portion of treatment effect on QoL is mediated by UED. Rehabilitation practices that prevent and alleviate UED are likely to improve QoL for breast cancer survivors.

Secretan's syndrome is a rare clinical condition with recurrent swelling of the forearm and dorsum of the hand, together with flexion contracture of the fingers and a thumb that is spared. The disease is associated with automutilation. We present a typical case of a 42-year old women with Secretan's syndrome.

[Free flaps use in chronic wounds: Retrospective study about 91 cases]. / Utilisation des lambeaux libres dans la prise en charge des plaies chroniques.

INTRODUCTION: Chronic wounds represent a major health challenge with no current standardized surgical treatment. The use of free flaps is little discussed in the literature, with a supposed propensity to failure given unfavorable local conditions and land often debility. We present here the analysis of our monocentric experience of the use of free flaps in the curative treatment of chronic wounds. PATIENTS ET METHODS: We performed a retrospective monocentric study over 18 years of all free flaps used for the treatment of a chronic wound between January 2001 and September 2016. Several criteria were evaluated on patients, wounds, free flaps used and immediate to late outcomes. RESULTS: Ninety-one patients were included (sex ratio M/F: 3.55) with an average age of 41.6±16 years. Wounds were localized to the leg in 92.3% of cases and 58% of patients had initial osteomyelitis. The flaps used were predominantly muscle flaps (61.6%). The flaps survival rate was 92.3%. With a mean follow-up of 50 months, the reconstructive failure rate was 20.9%. The presence of a chronic osteomyelitis is the only statistically significant factor of reconstruction failure (P=0.0169) with a risk of failure multiplied by 5. CONCLUSION: Our study demonstrates that the reliability of free flaps in the treatment of chronic wounds is comparable, regardless of the time since the initial cutaneous lesion, to that existing in the treatment of acute wounds or in the reconstruction after oncological excision. The presence of a chronic osteomyelitis, however, represents a major risk of reconstruction failure by increasing 5 times the risk of failure. Recent changes in the integumentary reconstruction paradigm of the lower limb will undoubtedly allow in the next few years to establish more rationally the place of muscle free flaps in the therapeutic armamentarium of chronic wounds.

Arterial Injury in the Upper Limb Resulting from Dog Bite.

Dog bites in the upper limbs have particular significance, because despite the small size of the puncture wounds, penetration is deep, causing serious injuries to deeper structures. There is currently very little data relating to upper extremity dog bite arterial injury. We present the case of a 32-year-old man who sustained a dog bite injury to his right arm, leading to direct puncture and spasm of the brachial artery. He was successfully treated with a jump bypass graft to the right brachial artery, with the use of the reversed ipsilateral cephalic vein as a conduit. We identified 34 cases in the literature reporting upper limb arterial injury secondary to dog bite. Twenty-two cases in the literature detailed axillobrachial artery damage (65%), 24% radial artery, 3% ulnar artery, and 9% combined. Presentation was most commonly with diminished pulses found in at least 45% of the patients. Arterial thrombosis occurred in 29% of cases of single artery injury, transection in 15%, intimal tear in 9% of cases, and undisclosed in 44%. Management most commonly included interposition graft (47%) and primary repair (20%), while 15% did not undergo surgical intervention, 9% underwent ligation, and 3% were treated with thromboembolectomy. Follow-up data for these patients are scarce, with some experiencing residual neurological deficit. This report highlights the importance of prompt recognition and treatment of vascular injury following dog bite to attain an optimal outcome and minimize complications.

Upper Extremity Patterns of Injury and Management at a Plastic and Reconstructive Surgery Referral Center in Mexico City.

BACKGROUND: Acute upper extremity injuries remain one of the most common consultations in the emergency departments for plastic surgery services. These injuries can affect a person's quality of life and negatively affect work-related or social interactions if not properly managed. We aim to evaluate our experience and management in a specialized referral center in Mexico City. METHODS: A retrospective review was performed. All patients with hand trauma managed by our service from July 2010 to June 2015 were included; their demographic characteristics were described as well as the most common patterns of injury, management, and outcome. RESULTS: A total of 4751 patients with injuries in the upper extremities were included, 77% were males with a mean age of presentation of 26.9 ± 17.9 years; the age group most commonly affected was between 16 to 30 years (39%); 54% of the cases affected the right hand. Lacerative wounds were the most common mechanism of injury (60.7%), followed by blunt trauma (28.7%). Management was surgical in 87% of the cases. CONCLUSIONS: Upper extremity trauma encompasses a wide range of clinical presentations, from simple lacerations to catastrophic injuries that require extensive or multiple reconstructive procedures. The clear understanding of the trauma mechanisms and how they are related with certain patterns of injury might maximize awareness and guide a surgeon's management effectively.

Impact of traumatic upper-extremity amputation on the outcome of injury caused by an antipersonnel improvised explosive device

Background: We have previously reported a higher than expected rate of upper-extremity amputation (UEA) in victims of an antipersonnel improvised explosive device (AP-IED) compared with a similar cohort injured by antipersonnel mines (APM). The goal of this study was to describe the rate, severity and impact of UAE caused by an AP-IED. Methods: We analyzed a prospective database of 100 consecutive dismounted AP-IED victims with pattern 1 injuries to compare the outcomes of the cohort with UEA to that without. Results: We found that UEA (8 above elbow, 19 below elbow, 1 through elbow, 3 hand, 15 digit(s)) was much more prevalent with AP-IED than with APM (40% v. 6%, p < 0.001). In addition, UEA was associated with a higher rate of multiple amputations (39 [98%] v. 32 [53%], p < 0.001), bilateral lower-extremity amputation (LEA; 33 [82.5%] v. 30 [53.3%], p = 0.003) and facial injury (8 [20%] v. 4 [6.4%], p = 0.044), but not with pelvic disruption (10 [25%]), genitoperineal mutilation (19 [48%]), eye injury (6 [15%]), or skull fracture (6 [15%]). The fatality rate was higher in patients with UEA than in those without (12 [30%] v. 7 [12%], p = 0.022). Conclusion: Upper-extremity amputation is more prevalent with AP-IED than APM. Presence of UEA is associated with more severe injury and increased risk of death in AP-IED victims. Upper-limb injury has significant consequences for rehabilitation from LEA, which universally accompanies UEA in AP-IED victims. Upper-extremity injury should be amenable to prevention by innovative personal protective equipment designed to protect the flexed elbow.

Contexte: Nous avons déjà fait état d'un taux plus élevé que prévu d'amputations des membres supérieurs (AMS) chez les victimes d'engins explosifs artisanaux (EEA) comparativement à une cohorte similaire blessée par des mines antipersonnel (MAP). L'objectif de cette étude est de décrire le taux, la gravité et l'impact des AMS causées par des EEA. Méthodes: Nous avons analysé une base de données prospective de 100 victimes consécutives d'EEA alors qu'elles se trouvaient hors de leur véhicule et présentant des blessures de type 1 afin de comparer les résultats des cohortes ayant subi ou non des AMS. Résultats: Nous avons constaté que l'AMS (8 au-dessus du coude, 19 sous le coude, 1 au niveau du coude, 3 mains et 15 doigts) était beaucoup plus prévalente avec les EEA qu'avec les MAP (40 % c. 6 %, p < 0,001). De plus, l'AMS a été associée à un taux plus élevé d'amputations multiples (39 [98 %] c. 32 [53 %], p < 0,001), d'amputations bilatérales des membres inférieurs (AMI) (33 [82,5 %] c. 30 [53,3 %], p = 0,003) et de blessures au visage (8 [20 %] c. 4 [6,4 %], p = 0,044), mais non de blessures au bassin (10 [25%]), de mutilations génitopérinéales (19 [48 %]), de blessures oculaires (6 [15 %]), ou de fractures du crâne (6 [15 %]). Le taux de létalité a été plus élevé chez les patients ayant subi une AMS que chez ceux qui n'en ont pas subi (12 [30 %] c. 7 [12 %], p = 0,022). Conclusion: L'amputation des membres supérieurs est plus prévalente avec les EEA qu'avec les MAP. L'AMS est associée à des blessures plus graves et à un risque plus grand de décès chez les victimes d'un EEA. Les blessures aux membres supérieurs ont de graves conséquences sur la réadaptation nécessaire après l'AMI, qui accompagne presque toujours l'AMS chez les victimes d'un EEA. Les blessures aux membres supérieurs devraient pouvoir être évitées grâce à de l'équipement de protection individuelle novateur conçu pour protéger le coude fléchi.

Radial Artery Compression with Threatened Transection: Catfish Injury in a Pediatric Patient.

Marine animal injuries are rare causes of emergency room visits and vascular injuries worldwide. Penetrating injuries from marine animals risk damage to vasculature, and physicians must be alert to such possibilities. We report a 7-year-old boy with penetrating trauma and retained foreign body in the forearm from a catfish injury. Initial imaging suggested transection of the radial artery, but on exposure in a controlled setting the foreign body was found to compress the artery without any vascular injury. No vascular repair was needed after foreign body removal.

Flexor Digitorum Superficialis Tear in a Wakeboarder: An Unusual Clinical Case.

Tears in the flexor digitorum superficialis muscle belly are rare injuries with one single case reported in the literature. In this article, we describe the first case of muscle tear of the flexor digitorum superficialis resulting from a wakeboarding trauma. The wakeboarder presented with pain localized in the anterior forearm, and early symptoms of carpal tunnel syndrome. Ultrasonography demonstrated an intramuscular hematoma of the flexor digitorum superficialis myotendinous junction, which compressed the median nerve. After conservative treatment, the patient was asymptomatic and returned to his usual daily activities and sports within 5 weeks of the injury. In patients with a wakeboard trauma and similar presentations, a tear in the flexor digitorum superficialis muscle belly should be suspected.

The Impact of Safety Regulations on the Incidence of Upper-Extremity Power Saw Injuries in the United States.

PURPOSE: Over 50,000 power saw-related injuries occur annually in the United States. Numerous safety measures have been implemented to protect the users of these tools. This study was designed to determine which interventions, if any, have had a positive impact on the safety of the consumer or laborer. METHODS: We queried the National Electronic Injury Surveillance System database for hand and upper-extremity injuries attributed to power saws from 1997 to 2014. Demographic information including age, sex, date of injury, device, location, body part involved, diagnosis, and disposition was recorded. We performed statistical analysis using interrupted time series analysis to evaluate the incidence of injury with respect to specific safety guidelines as well as temporal trends including patients' age. RESULTS: An 18% increase in power saw-related injuries was noted from 1997 (44,877) to 2005 (75,037). From 2006 to 2015 an annual decrease of 5.8% was observed. This was correlated with regulations for power saw use by the Consumer Safety Product Commission (CPSC) and Underwriters Laboratories. Mean age of injured patients increased from 48.8 to 52.9 years whereas the proportion of subjects aged less than 50 years decreased from 52.8% to 41.9%. These trends were most pronounced after the 2006 CPSC regulations. CONCLUSIONS: The incidence of power saw injuries increased from 1997 to 2005, with a subsequent decrease from 2006 to 2015. The guidelines for safer operation and improvements in equipment, mandated by the CPSC and Underwriters Laboratories, appeared to have been successful in precipitating a decrease in the incidence of power saw injuries to the upper extremity, particularly in the younger population. CLINICAL RELEVANCE: The publication of safety regulations has been noted to have an association with a decreased incidence in power saw injuries. Based on this, clinicians should take an active role in their practice as well as in their professional societies to educate and counsel patients to prevent further injury.

Major League Baseball pace-of-play rules and their influence on predicted muscle fatigue during simulated baseball games.

Major League Baseball (MLB) has proposed rule changes to speed up baseball games. Reducing the time between pitches may impair recovery from fatigue. Fatigue is a known precursor to injury and may jeopardise joint stability. This study examined how fatigue accumulated during baseball games and how different pace of play initiatives may influence fatigue. Pitcher data were retrieved from a public database. A predictive model of muscle fatigue estimated muscle fatigue in 8 arm muscles. A self-selected pace (22.7 s), 12 s pace (Rule 8.04 from the MLB) and a 20 s rest (a pitch clock examined in the 2014 Arizona Fall League (AFL)) were examined. Significantly more muscle fatigue existed in both the AFL and Rule 8.04 conditions, when compared to the self-selected pace condition (5.01 ± 1.73%, 3.95 ± 1.20% and 3.70 ± 1.10% MVC force lost, respectively). Elevated levels of muscle fatigue are predicted in the flexor-pronator mass, which is responsible for providing elbow stability. Reduced effectiveness of the flexor-pronator mass may reduce the active contributions to joint rotational stiffness, increasing strain on the ulnar collateral ligament (UCL) and possibly increasing injury risk.

Upper limb birth trauma in a Jordanian population: a prospective study at King Hussein Medical Centre, Amman, Jordan.

OBJECTIVE: To determine the incidence of and the main risk factors related to upper limb injury at birth. METHODS: This prospective study was conducted at the King Hussein Medical Centre, Amman, Jordan, from October 2014 to May 2015, and comprised newborns. The probable predisposing factors for upper limb birth injury and their relation to injury were analysed. SPSS 17 was used for data analysis. RESULTS: Of the 5,030 live births, 5,003(99.46%) newborns were without and 27(0.54%) were with upper limb birth trauma (5.4 injuries per 1,000 live births). Moreover, 2,565(51%) were boys and 2,465(49%) were girls. Of the injured, 20(74%) patients had clavicle fracture, 3(11.1%) each had brachial plexus injuries and fractures to the humerus, and 1(3.7%) had olecranon fracture, translating into an incidence of 3.97, 0.6 and 0.2 per 1,000 live births, respectively. CONCLUSIONS: Upper limb injury was not uncommon at birth. In most cases, such injuries were unpredictable and unpreventable.

Upper extremity fractures among hospitalized road traffic accident adults.

BACKGROUND: Upper extremity fractures (UEFs) associated with road traffic accidents (RTAs) may result in long-term disability. Previous studies have examined UEF profiles with small patient populations. The objective of this study was to examine the injury profiles of UEFs in all mechanisms of injury related to RTAs. METHODS: Data on 71,231 RTA adult patients between 1997 and 2012 whose records were entered in a centralized country trauma database were reviewed. Data on UEFs related to mechanism of injury (car, motorcycle, bicycle, and pedestrian) including associated injuries, multiple UEFs, and frequency of UEF were analyzed. RESULTS: Of 71,231 adult RTA cases recorded in 1997-2012, 12,754 (17.9%) included UEFs. Motorcycle (27%) and bicycle riders (25%) had the greater risk for UEF (P<.0001). Of 12,754 patients with UEFs, 9701 (76%) had other injuries. Pedestrians (86%) and car occupants (81%) had the greater risk for associated injuries (P<.0001). Most of the injuries were head/face/neck (52%), lower extremities (49%), and chest (46%) injuries (P<.0001). Twenty-two percent of all cases had multiple UEFs. The motorcycle riders (27%) had the greater risk for multiple UEFs (P<.0001). Of 12,754 patients with UEFs we found 16,371 UEFs. Most of the fractures were in the radius (22%), humerus (19%), and clavicle (17%) (P<.0001). CONCLUSIONS: This study contributes the largest database on reported adult UEFs related to all mechanisms of injury in RTAs and finds the comparative epidemiology of associated injuries, multiple UEFs, and frequency of UEFs. It is important that the treating surgeon is aware of the complexity of the UEF patient, the strong possibility for associated injury, the possibility for multiple fractures in the upper limbs, and the most common fractures associated with each mechanism of accident.

Anti-vibration gloves?

For exposure to hand-transmitted vibration (HTV), personal protective equipment is sold in the form of anti-vibration (AV) gloves, but it remains unclear how much these gloves actually reduce vibration exposure or prevent the development of hand-arm vibration syndrome in the workplace. This commentary describes some of the issues that surround the classification of AV gloves, the assessment of their effectiveness and their applicability in the workplace. The available information shows that AV gloves are unreliable as devices for controlling HTV exposures. Other means of vibration control, such as using alternative production techniques, low-vibration machinery, routine preventative maintenance regimes, and controlling exposure durations are far more likely to deliver effective vibration reductions and should be implemented. Furthermore, AV gloves may introduce some adverse effects such as increasing grip force and reducing manual dexterity. Therefore, one should balance the benefits of AV gloves and their potential adverse effects if their use is considered.
