Clinical analysis of 1301 children with hand and foot fractures and growth plate injuries

BACKGROUND

Fractures of hands and feet are common in children, but relevant epidemiological studies are currently lacking. We aim to study the epidemiological characteristics of hand and foot fractures and growth plate injuries in children and provide a theoretical basis for their prevention, diagnosis, and treatment.

METHODS

We retrospectively analyzed the data of children with hand and foot fractures who were hospitalized at Shenzhen Children's Hospital between July 2015 and December 2020. Data on demographic characteristics, fracture site, treatment method, etiology of injury, and accompanying injuries were collected. The children were divided into four age groups: infants, preschool children, school children, and adolescents. The fracture sites were classified as first-level (the first-fifth finger/toe, metacarpal, metatarsal, carpal, and tarsal) and second-level (the first-fifth: proximal phalanx, middle phalanx, distal phalanx, metacarpal, and metatarsal) sites. The changing trends in fracture locations and injury causes among children in each age group were analyzed.

RESULTS

Overall, 1301 children (1561 fractures; 835 boys and 466 girls) were included. The largest number of fractures occurred in preschool children (n = 549, 42.20%), with the distal phalanx of the third finger being the most common site (n = 73, 15.57%). The number of fractures in adolescents was the lowest (n = 158, 12.14%), and the most common fracture site was the proximal phalanx of the fifth finger (n = 45, 29.61%). Of the 1561 fractures, 1143 occurred in the hands and 418 in the feet. The most and least common first-level fracture sites among hand fractures were the fifth (n = 300, 26.25%) and first (n = 138, 12.07%) fingers, respectively. The most and least common first-level foot fracture locations were the first (n = 83, 19.86%) and fourth (n = 26, 6.22%) toes, respectively. The most common first-level and second level etiologies were life related injuries (n = 1128, 86.70%) and clipping injuries (n = 428, 32.90%), respectively. The incidence of sports injuries gradually increased with age, accounting for the highest proportion in adolescents (26.58%). Hand and foot fractures had many accompanying injuries, with the top three being nail bed injuries (570 cases, 36.52%), growth plate injuries (296 cases, 18.96%), and distal severed fracture (167 cases, 10.70%). Among the 296 growth plate injuries, 246 occurred on the hands and 50 on the feet.

CONCLUSIONS

In contrast to previous epidemiological studies on pediatric hand and foot fractures, we mapped the locations of these fractures, including proximal, shaft, distal, and epiphyseal plate injuries. We analyzed the changing trends in fracture sites and injury etiologies with age. Hand and foot fractures have many accompanying injuries that require attention during diagnosis and treatment. Doctors should formulate accident protection measures for children of different ages, strengthen safety education, and reduce the occurrence of accidental injuries.

Youngest hand injury during cesarean delivery: A case report

An emergency cesarean surgery resulted in extensor tendon lacerations in a 27-week-old preterm fetus. This injury is unique because fetal hand lacerations rarely occur, and to the best of our knowledge, this is the youngest case of hand injury during cesarean delivery reported in the literature. This case report sets the framework for a more in-depth investigation of the incidence and treatment options for fetal lacerations, with an emphasis on the less common but clinically important hand lacerations that can occur during cesarean section. LEVEL OF EVIDENCE: Therapeutic IV.

Hand Fractures-Management and the Complications That Inevitably Occur: Metacarpal Fractures

Metacarpal fractures are among the most common hand fractures. To properly manage these injuries, surgeons must understand the anatomy, biomechanics, clinical assessment, surgical and nonsurgical treatment options, and potential complications. Metacarpal head fractures often require surgical treatment to restore the joint surface by using a variety of techniques. Metacarpal neck fractures are usually stable injuries that do not require surgical intervention, but surgeons must know when surgical intervention is indicated. Fractures of the metacarpal shaft can be treated surgically and nonsurgically and may be associated with large bone defects or soft-tissue injuries that require careful consideration. Finally, fractures involving the carpometacarpal joints must be promptly managed to avoid long-term complications, potentially requiring salvage procedures.

Minimally invasive percutaneous screw internal fixation under robot navigation for the treatment of a hamate bone fracture

PURPOSE

Hamate fractures are rare fractures of the wrist and there is still no consensus on the optimal treatment for these fractures, especially hook of hamate fractures. Herein, the authors present a case study of a series of patients who were treated with closed reduction and minimally invasive percutaneous fixation under robot navigation.

METHODS

This retrospective study reviewed 14 patients who had nondisplaced or minimally displaced hamate fractures on computerized tomography images and were treated using the treatment in our centre from November 1, 2019, to October 31, 2022. At the final follow-up, the flexion-extension and radial-ulnar range of motion of the wrist were measured, and the grip strength and pinch strength were measured. The pain of the wrist was assessed using the visual analogue scale (VAS). The Mayo wrist score reflected the recovery of the wrist.

RESULTS

The mean total operative duration was 40.1 min. All the fractures showed union at a mean of 3.0 months. At a mean follow-up of 23.3 months (range 6-36 months), the mean VAS score was 0.7, the average Mayo wrist score was 95, and the mean pinch strength and grip strength were 11.3 and 38.7 kg, respectively. The flexion-extension arc was 138.3°, the mean radial and ulnar deviation arc was 63.8°, and the mean pronation-supination arc was 172.3°. And the time of return to the original occupation was mean 4 months (3~6 months). There were no complications, such as infection or nerve paralysis.

CONCLUSIONS

This study suggests that nondisplaced or minimally displaced hamate hook fractures can be successfully treated by closed reduction and internal fixation with a headless compression screw with the assistance of robot navigation, and the small fragment of fracture can be accurately fixed with minimal iatrogenic injury.

A New Source of Mutilating Hand Injuries: The Side-by-Side Utility Terrain Vehicle

BACKGROUND

Rates of mutilating hand injuries are increasing from accidents caused by all-terrain vehicles (ATVs) and the recently popularized side-by-side utility terrain vehicles (UTVs). Increasing surgeon familiarity with upper extremity (UE) injury patterns, severity, and outcomes following ATV and UTV accidents may improve patient care and advocacy.

METHODS

Retrospective comparisons of UE injury patterns, severity, hospital and intensive care unit (ICU) admission lengths, and number of operations were made between ATVs and UTVs. Findings were analyzed with Fisher exact tests, multivariate analysis of variance, analyses of variance with post hoc analyses, and multiple linear regressions.

RESULTS

A total of 154 cases were identified for inclusion (ATV, n = 87; UTV, n = 67). Patient ages ranged from 4 to 89 years. The UTV group contained significantly more hand and finger injuries, and more of the fractures were open ( P = 0.005, P < 0.001, and P < 0.001, respectively). Riders of UTVs had nearly three times as many mutilating hand injuries and a nearly ninefold increase in amputations compared with ATV riders ( P < 0.001 and P < 0.001, respectively). On average, the UTV group spent 2.5 additional days in the hospital, 0.91 additional days in an ICU, and had 1.3 additional operations ( P = 0.001, P = 0.007, and P < 0.001, respectively). Vehicle type was the only variable significantly correlated with days in the hospital, ICU, and number of UE operations ( P = 0.002, P = 0.008, and P < 0.001, respectively).

CONCLUSIONS

Hand surgeons are in a unique position to serve as forerunners for increasing public awareness of off-road vehicle risks and promoting rider safety. Collaborating with manufacturers and emergency care providers and directing teaching initiatives may improve patient outcomes.

Comparison of Finger, Hand, and Wrist Injuries in the US Air Force to US Workers

OBJECTIVE

Fingers, hands, and wrists (FHW) are the most frequently injured body parts in work-related injuries. This study described and compared FHW injuries among enlisted, officer, and civilian US Air Force (USAF) personnel to those in the US workforce.

METHODS

All work-related, noncombat FHW injuries (≥1 lost workday) and demographics among USAF personnel and US workforce (2008-2018) were included. The USAF FHW injury rates were age adjusted to the US employment and compared by sex, source, event, and nature of the injuries.

RESULTS

Finger, hand, and wrist injuries were significantly lower among the USAF personnel and among females. In both populations, FHW injuries from falls were higher and increased with age group among females. Males had higher overall FHW injuries from contact with objects and equipment.

CONCLUSIONS

Prevention efforts should focus on understanding risk factors and sharing successful prevention activities.

Firearm Injuries to the Wrist and Hand in Children and Adults: An Epidemiologic Study

BACKGROUND

Gunshot wounds (GSWs) to the wrist and hand are a major health and economic burden in the United States. There are few studies examining the circumstances and epidemiological factors surrounding these injuries. This study assesses the epidemiological factors, as well as the shooting circumstances, injury details, and surgical management of wrist and hand GSWs in children and adults.

METHODS

Medical records and radiographs were reviewed for all patients with ballistic injury to the wrist or hand treated at an urban academic level 1 trauma center from 2016 to 2019. Fisher exact and Pearson χ2 tests were used to assess differences between groups.

RESULTS

Two hundred forty-nine victims (29 children, 220 adults) with complete documentation were identified. Among 180 victims with known shooting circumstances, 132 (70%) were shot by another person and 110 (65%) were injured by intentional gunfire. Eighty-seven victims (35%) suffered a concurrent GSW to another body region. Metacarpal fracture was the most commonly diagnosed bony injury (37%), followed by proximal phalanx fracture (25%). One hundred twenty-nine victims (52%) underwent surgery following their injuries. Nerve discontinuity was diagnosed in 27 victims (11%), while 20 victims (8%) had vascular disruption. There was no significant difference between children and adult victims' type of fracture, concurrent injuries, rates of surgery, or in the most common fracture fixation method.

CONCLUSIONS

Most wrist and hand GSW victims were injured due to intentional, non-self-inflicted gunfire. Most patients present with hand fractures, and fortunately, nerve and vascular disruptions are uncommon.

Persistent Unilateral Force Production Deficits Following Hand Injury in Experienced Climbers: A Reliability and Retrospective Injury Study

INTRODUCTION

In climbing, research is needed to guide clinical and training advice regarding strength differences between hands. The objectives of this study were to establish test-retest reliability of a field-based apparatus measuring sport-specific unilateral isometric hand strength and to investigate whether these measures detect between-hand differences in climbers with and without a history of unilateral hand injury.

METHODS

A reliability and case-control injury study was carried out. Seventeen intermediate-advanced climbers without and 15 intermediate-advanced climbers with previous unilateral hand injury participated. Unilateral isometric fingertip flexor strength was assessed during maximal voluntary contraction (MVC) and peak rate of force development (RFD) tests in full-crimp overhead position. The magnitude of within-group between-hand differences was calculated using a generalized estimating equation to evaluate if prior injury was associated with lower MVC and RFD outcomes and whether hand dominance influenced the magnitude of these effects. The control group was assessed 1 wk later to determine intraclass correlation coefficients (ICCs) for all measures.

RESULTS

The MVC (ICC 0.91-0.93) and the RFD (ICC 0.92-0.83) tests demonstrated moderate-to-high reliability. When accounting for handedness, those with prior injury showed 7% (P=0.004) reduced MVC and 13% (P=0.008) reduced RFD in the injured hand. The nondominant hand was also significantly weaker in MVC (11%, P<0.001) and RFD (12%, P=0.02) outcomes. For uninjured climbers, MVC and RFD were not significantly higher in the dominant hand (differing by 4% and 5%, respectively).

CONCLUSIONS

Previous climbing injury was associated with persistent weakness in the injured limb and exacerbated handedness effects. Therefore, recommendations for rehabilitation should be considered.

Hand injuries in Kenya: a chaff cutter menace

Introduction Hand injuries are a recognized occupational hazard from the use of chaff cutters. With increasing mechanization of farming in our region, the burden of hand injuries is poised to increase. Methods We conducted a descriptive study of 47 patients presenting with chaff cutter hand injuries at our center in one year. Results They were predominantly male (98%) and the majority (70%) were aged between 21 and 40 years. The majority of patients who had not resumed work were those with severe injuries and those who had had an amputation. There was a positive correlation between age category and severity of injury. Discussion Chaff cutter injuries contribute considerably to hand amputations at our center. The majority of patients with severe injuries and those undergoing amputations do not return to gainful activities one year after sustaining the injury, suggesting increased dependency. Further research is paramount to identify safety features of chaff cutters in this region.

Prevalence of household meat grinder-induced severe hand injuries: A retrospective clinical study

BACKGROUND

The aim of the study was to evaluate patients with household meat grinder-related hand injuries who presented to our hospital between 2009 and 2020, investigate the causes of these injuries, and discuss prevention methods.

METHODS

Sixty-four patients injured by a meat grinder were retrospectively screened. The patients aged one to 18 years were evaluated in the pediatric group and those over 18 years were evaluated in the adult group. The relationships between age, gender, location of injury (right hand, left hand, wrist, and fingers), and amputation level were analyzed.

RESULTS

Twenty-two of the patients were children, of whom 13 were boys and nine were girls, with a mean age of 11 (range 1-18) years. There were 42 adult patients comprising 15 males and 27 females, and their mean age was 42 (range 19-74) years. In the pediatric group, the rate of amputations at the metacarpophalangeal (MP) and wrist joint levels were significantly higher compared to the adults (p<0.005). In the adult group, the rate of amputations at the third finger distal interphalangeal (DIP) joint was significantly higher compared to the pediatric group (p=0.007). There was no statistically significant difference between the pediatric and adult groups regarding the rate of amputations at the thumb and little finger levels.

CONCLUSION

There seems to be a lack of research to guide the development of strategies to prevent household meat grinder-related injuries, and this type of injury remains a national health problem. To prevent such injuries, occupational safety should be considered not only in workplaces but also at home, and information should be provided to raise the awareness of the society.

[ACUTE INJURY TO FLEXOR TENDONS OF THE HAND: ASSESSMENT, DIAGNOSIS AND TREATMENT]

Hand lacerations are common injuries seen by the primary care physician. Even seemingly small cuts carry a high risk of injury to flexor tendons of the hand which requires surgical treatment by a specialist. Elucidation of the relevant history, along with a dedicated and focused physical examination is imperative for an early intervention which, along with a meticulous surgical technique and dedicated rehabilitation by occupational therapists, will lead to a much improved functional prognosis for the patient. This is a brief review of the anatomy and physiology of flexor tendons injury and repair, with historical milestones of developments in the approach to the injury. The article also highlights the surgical procedure brought forth by the late Professor Isidor Kessler, one of the founders of surgery of the hand in Israel, presented here as an overview and guidance to the primary care physician.

Impact of COVID-19 pandemic on hand injuries

BACKGROUND

The aim of the study was to evaluate etiologies of hand injuries in emergency department (ED), to compare the etiologies of hand injuries at the time of this study with the previous year, to assess whether novel coronavirus-2019 (COVID-19) pandemic affected the treatment decisions, and to investigate the COVID-19 infection rate within the first 14 days after admission.

METHODS

A total of 229 patients admitted to ED with hand injury between March 15 and April 30, 2020, were included in the study. The control group consisted of 439 ED admissions with hand injury in the previous year (March 15-April 30, 2019). Data including age, sex, cause of trauma, treatment, and COVID-19 infection status within 14 days after ED admission were compared between groups.

RESULTS

The mean age was 32.30±15.63 years in the study group and 30.85±18.54 years in the control group. The number of patients consulted to the surgery department decreased by 52.6% and the number of patients admitted to ED with hand injuries de-creased by 47.6% during the pandemic, compared to the previous year (p=0.0001). The incidence of home accidents increased and the glass cuts and penetrating/perforating injuries were the most common causes during the pandemic most of which occurred at home.

CONCLUSION

The COVID-19 pandemic-mandated social restrictions led to a significant decrease in the number of ED admissions with hand injuries and the type of injuries. The incidence of home accidents increased with more time spent indoors. This study may be a useful guide for ED admissions of hand injury cases and management planning in the current and future pandemics.

Clinical outcome of pediatric hand burns and evaluation of neglect as a leading cause: A retrospective study

BACKGROUND

Majority of the pediatric burns happen when an adult is nearby the child. This suggests the role of adult carelessness or neglect as a cause of burns. The aim of this study is to provide clinical data on pediatric hand burns and to draw attention to the role of neglect in pediatric burn injuries.

METHODS

Children admitted to a tertiary burn center between September 2017 and October 2018 were included in the study. Epidemiological data including age, sex, etiology and place of injury, presence of caregiver nearby, physical signs of neglect or abuse, clinical outcomes including burned total body surface area, length of admittance, and complications were recorded.

RESULTS

A total of 335 pediatric burns were admitted to the burn center. Among them 89 patients with hand involvement were included in the study. Most of the patients were under the age of 6 (79.8%) and 88.8% of the burn accidents occurred indoors. Scalding was the main mechanism for hand burns. There was an adult nearby in 71.9% of the patients. Among patients with hand involvement, 19 (21.35%) were considered as neglect. All the neglect cases were under the age of 6.

CONCLUSION

Pediatric burn accidents occurred mainly at home, mostly with an adult around. Habits of drinking hot beverages, dangerous cooking practices and lack of awareness are some important issues leading to burn accident. Neglect is found in 21.35% of hand burns as the etiology. In addition to general preventive measures special attention should be paid to the signs of neglect in the evaluation of patients. These burns should also be reported to official services, as they may reflect inadequate supervision or neglect by the caregiver.

Iatrogenic hand trauma in institutionalized brain-injured patients: About 2 cases

The objective of this work was to draw the attention of caretakers for institutionalized brain-injured patients to the risk of iatrogenic trauma associated with improper manipulation of the fingers during hand opening for grooming. Two clinical cases of chronic open dislocation of the thumb and the fifth finger in institutionalized brain-injured patients were reviewed. Interrogation of the patients and their relatives did not reveal either the date or the mechanism of the injury. In the light of these two cases, it appears that better training of caretakers should make it possible to avoid iatrogenic trauma during hygiene care of institutionalized brain-injured patients.

Increases in Firework-Related Upper Extremity Injuries Correspond to Increasing Firework Sales: An Analysis of 41,195 Injuries Across 10 Years

INTRODUCTION

Between 2008 and 2017, the American Pyrotechnics Association reported a 41% increase in revenue from firework sales, with 2017 showing $885 million US dollars in consumer sales. We sought to evaluate the epidemiology of firework-related upper extremity injuries during this 10-year period, hypothesizing that hand/upper extremity injuries from fireworks were increasing in the United States.

METHODS

Observational epidemiologic assessment of a weighted cohort of patients via the National Electronic Injury Surveillance System from 2008 to 2017. The National Electronic Injury Surveillance System provides a nationwide probability sample of injuries related to consumer products based on emergency department visits collected from a cohort of about 100 US hospitals.

RESULTS

A total of 1,079 patients representing an estimated 41,195 firework-related upper extremity injuries presented to US emergency departments from 2008 to 2017. The number of injuries increased significantly from 2,576 in 2008 to 5,101 in 2017 (R2 = 0.85, R = 0.92, P < 0.001). A Spearman rank-order correlation determined that there was a strong, positive correlation between the increase in firework sales and the increase in injuries (rs = 0.939, P < 0.01). The overwhelming majority of firework-related injuries were seen in males (77%) aged 11 to 29 years (48%). The hand and fingers accounted for 85.8% of injuries, with the thumb being the most commonly injured body part (51.3%). Burns were the most common injury across all body sites except the wrist, where fractures were most common.

CONCLUSION

Ten-year firework-related upper extremity injuries increased, corresponding to increased consumer sales across the same period. This study provides previously absent population-level data to provide a framework for discussion among policy makers and physicians alike in an attempt to mitigate the use of fireworks and their associated upper extremity injuries.

High-Pressure Injection Injuries of the Hand: A 10-Year Retrospective Analysis at a Single Academic Center

INTRODUCTION

The incidence of high-pressure injection injuries of the hand is low. Although the occurrence is rare, the precarious progression of the injury exacts prompt surgical evaluation in order to avoid complications and amputation. The current study was devised in order to make comparisons to the current data, in addition to supplementing the literature with observations regarding clinical course and management.

METHODS

A multisurgeon, retrospective chart review from a single institution was performed. Inclusion criteria included cases involving a high-pressure injection injury to the hand that underwent surgical management. Patient demographics, injury details, and hospital course were all reviewed and recorded.

RESULTS

This retrospective review identified 20 cases meeting criteria, all of which involved males. The average age at time of injury was 39.7 years (range, 21-71 years). The incidence of injection injuries over a 10-year time period was 2.1 cases per year. The nondominant hand was injured in 11 cases (63%). The most common site of injury was the index finger with 11 recorded incidents (55%). Other reported locations included the metacarpal (40%) and small finger (5%). Occupational data included 10 construction workers, 5 painters, and 2 cleaning crew members, and 3 had nonmanual occupations. Paint was the most commonly injected substance with 17 reported cases (85%). On average, the delay until surgery was observed to be 21.9 hours (n = 16). Only 1 patient underwent surgery at 6 hours after surgery. The average number of procedures performed was 1.8 (range, 1-4). Hospitalization duration was on average 3.9 days (range, 1-9 days), and the average follow-up length was 69 days (range, 7-112 days). There were no identified cases that necessitated amputation.

CONCLUSIONS

This form of injury most commonly affects male, middle-aged laborers. Our study found very low amputation rates when compared with the current literature, despite observing longer delays to surgery according to current recommendations. Limited comparisons can be made from data regarding clinical course and management because of the small sample size of the current study and the limited published data. This indicates a need for further exploration and collection of data involving parameters such as clinical course and management.

Differences in Rupture Patterns and Associated Lesions Related to Traumatic Distal Triceps Tendon Rupture Between Outstretched Hand and Direct Injuries

BACKGROUND

Traumatic distal triceps tendon rupture results in substantial disability in the absence of an appropriate diagnosis and treatment. To the best of our knowledge, differences in the degree of injury according to the injury mechanisms and associated lesions are not well known.

QUESTIONS/PURPOSES

In this study, we asked: (1) What differences are seen in triceps tear patterns between indirect injuries (fall on an outstretched hand) and direct injuries? (2) What are the associated elbow and soft tissue injuries seen in indirect and direct triceps ruptures?

METHODS

Between 2006 and 2017, one center treated 73 elbows of 72 patients for distal triceps tendon rupture. Of those, 70% (51 of 73 elbows) was excluded from this study; 8% (6 of 73) were related to systemic diseases, 59% (43 of 73) sustained open injuries, and 3% (2 of 73) were related to local steroid injections. We retrospectively collected data on traumatic distal triceps tendon rupture in 30% (22 of 73) of elbows at a single trauma center during a 10-year period. A fall on an outstretched hand was the cause of injury in 15 patients and direct blow by object or contusion were the cause in seven. MRI and surgery were performed in all patients. Traumatic distal triceps tendon rupture was classified by the Giannicola method, which is classified according to the depth and degree of the lesion based on MRI and surgical findings. Associated fractures and bone contusions on MRI were characterized. Ligament injuries on MRI was divided into partial and complete rupture. Agreement between the MRI and intraoperative findings for the presence of a traumatic distal triceps tendon rupture was perfect, and the Giannicola classification of traumatic distal triceps tendon rupture was good (kappa = 0.713).

RESULTS

In the indirect injury group (fall on an outstretched hand), 15 of 15 patients had injuries that involved only the tendinous portion of the distal triceps, but these injuries were not full-thickness tears, whereas in the direct injury group, three of seven patients had a full-thickness rupture (odds ratio [OR] 1.75 [95% CI 0.92 to 3.32]; p = 0.02). The direct injury group had no associated ligamentous injuries while 14 of 15 patients with indirect injuries had ligamentous injuries (OR 0.13 [95% CI 0.02 to 0.78]; p < 0.001; associated injuries in the indirect group: anterior medial collateral ligament [14 of 15], posterior medial collateral ligament [7 of 15], and lateral collateral ligament complex [2 of 15]). Similarly, one of seven patients in the direct injury group had a bone injury (capitellar contusion), whereas 15 of 15 patients with indirect ruptures had associated fractures or bone contusions (OR 16.0 [95% CI 2.4 to 106.7]; p < 0.001).

CONCLUSION

A fall on an outstretched hand may result in an injury mostly to the lateral and long head of distal triceps tendon and an intact medial head tendon; however, direct injuries can involve full-thickness ruptures. Although a traumatic distal triceps tendon rupture occurs after a fall on an outstretched hand, radial neck, capitellar, and medial collateral ligament injury can occur because of valgus load and remnant extensor mechanisms. Based on our finding, the clinician encountering a distal triceps tendon rupture due to a fall on an outstretched hand should be aware of the possibility of remaining elbow extensor mechanism by intact medial head tendon portion, and associated injuries, which may induce latent complications.

Tool and machinery-related hand injuries: a review of national Hospital Episodes Statistics and data from a tertiary hand unit

We sought to identify national trends in tool and machinery-related hand injuries. Hospital Episodes Statistics data in England from 1998 to 2017 were analysed. Data from our hand unit from 2011 to 2017 were also reviewed to establish the types of tool and machinery causing injury. During the 19-year study period 210,291 admissions occurred as a result of tool and machinery-related injuries. The overall incidence rate and mean age increased. The largest increase in incidence rate was in the oldest age group (75 years+). The incidence rate in children fell. During the period studied, 2150 patients underwent surgery in our unit for tool and machinery-related injuries. The hand was involved in 2069 (96%) of the injuries. Adult injuries were caused by a similar proportion of types of tool or machinery in all age groups. This study demonstrates a clear and sustained trend of increasing incidence of tool and machinery-related injuries in adults. The largest increase is in older patients.Level of evidence: IV.

Torture-induced hand electrical injury: A case report

The authors report an unusual case of hand electrical injury related to torture in a war refugee. The patient was referred for the reconstruction of bilateral hand function several years after being tortured. He presented with severe hand contractures combined with motor and sensory loss. After nonoptimal treatment in the acute period, the reconstruction options were limited by the delayed management. This unique clinical presentation can be explained by repetition of prolonged electrical shocks using a low-voltage current.

Firework Injuries of the Hand: An Analysis of Treatment and Health Care Utilization

Background: Firework injuries to the hand can be devastating due to the explosive and ballistic nature of these devices. The aim of this study was to describe the injury and treatment characteristics of patients requiring surgery for firework-related hand injuries and to investigate which factors are associated with an increased utilization of health care resources. Methods: A retrospective chart review of patients undergoing surgery for firework-related hand injuries at two American College of Surgeons level I trauma centers between 2005 and 2016 was performed. Twenty cases were identified. These patients were evaluated for demographics, injury characteristics, number and types of surgical interventions, length of stay, and utilization of health care resources. Bivariate analyses were performed to investigate which factors were associated with increased consumption of health care resources. Results: Injuries ranged from digital nerve injuries to traumatic amputation. Patients underwent a median of 3 surgical operations. More than half the patients underwent flap or skin graft coverage of a soft tissue defect. The median length of hospital stay was 7 days. Factors found to be associated with an increased utilization of surgical and hospital resources included a first web space injury, thumb fracture, and traumatic amputation of any digit. Conclusions: The morbidity inflicted by firework injuries to individual patients is substantial. Patients with severe injuries undergo a median of three surgical operations and have a long duration of initial hospital stay. Knowing which factors are associated with an increased utilization of resources can help prognosticate these preventable injuries.
