Three-Dimensional Quantitative Study and Functional Outcome Analysis of Coronoid Fracture in Different Elbow Injury Patterns.

BACKGROUND: Coronoid fractures are often part of a complex fracture-dislocation of the elbow. For an optimum prognosis, it is important to understand the characteristics of coronoid fractures in different elbow injury patterns. Significant differences in these characteristics have been observed in various studies, but these previous studies have suffered from limitations, such as insufficient quantification and unknown prognostic differences among different injury patterns. Therefore, we aimed to quantitatively analyze coronoid fracture characteristics and functional outcomes in different elbow injury patterns using 3D-CT. METHODS: All patients with coronoid fractures surgically treated at our hospital between January and December 2017 were categorized into three groups according to elbow injury pattern: PLRI, VPMRI and OFD. 3D models were reconstructed using Mimics 17.0, and the total volume (TV) and number of coronoid fragments (NCF) were measured. The coronoid process edge was classified into different anatomical regions, and each region was assigned a number to quantify the distribution of fracture lines. At the last follow-up, the ROM, VAS, MEPS, complications and reoperations were recorded. RESULTS: The ninety-two patients enrolled had an average age of 42±15 years and a male-to-female ratio of 66:26. The median TV in PLRI patients was less than that in VPMRI patients [431 (132, 818)mm3 vs. 1125 (746,1421)mm3,adjusted P<0.001] and OFD patients [431 (132, 818) mm3 vs. 2565 (381, 4076)mm3, adjusted P =0.001]. The median NCF in PLRI patients was also less than that in VPMRI patients [1 (1, 2) vs. 2 (1, 3), adjusted P=0.043]. Most of the PCFL-Rs (79%) were located around the volar edge of the lesser sigmoid notch. Compared with that of PLRI, the PCFL-Us of the VPMRI and OFD tended to be located on the more ulnodorsal side of the coronoid process edge. The median ROM [110 (90, 133), P=0.001] and the median MEPS [85 (68, 95), P=0.038] of patients with OFD were significantly less than those of patients with the other two patterns. The incidence of elbow stiffness (56%, 5/9, P=0.001) and implant-related irritation (44%, 4/9, P<0.001) in the OFD group was significantly higher than that in the other two groups. CONCLUSION: Coronoid fractures differ significantly in fragment volume, comminution severity and fracture line distribution among different elbow injury patterns. OFD has the worst functional outcomes among complex elbow injury patterns.

Sports-Related Musculoskeletal Injuries in Medical Students.

Background: Little attention is paid to the problem of sports-related injuries in amateur or nonathletes or recreational student athletes. We investigated the prevalence of sports-related musculoskeletal (MSK) injuries in medical students and attempted to identify the risk factors for these injuries. Methods: We conducted a cross-sectional questionnaire-based observational study on medical students of a tertiary care teaching hospital in central India. A total of 500 medical students were approached; the questionnaire consisted of details, such as age, gender, height, weight, predominant sport played or the sport during which they sustained an injury, estimated time spent playing every week, if they had undergone any formal training for the sport, any preexisting MSK condition, details of the injury and the treatment taken, if any, after joining medical school, and duration from getting injured to return to studies and sports. The odds ratio (OR) and logistic regression were calculated for multiple parameters. Statistical significance was set at P ≤ 0.05. Results: Seventy-four of the 402 students who responded reported sustaining a sports-related injury; 33 and 41 students reported injury while playing contact and noncontact sports, respectively. Of these, 58 students reported that they had received formal training in sports. Football, volleyball, cricket, and kabaddi were the sports during which most injuries occurred. The injury rate was 3.7 per 1000 playing or practice hours. Conclusions: Almost one-fifth of the students reported sustaining a sports-related MSK injury after joining medical school. The risk factors identified for these injuries were male gender, participation in team sports, participation in noncontact sports, and lack of adequate preparation or practice.

Age-specific Patterns of Intimate Partner Violence Related Injuries in US Emergency Departments.

PURPOSE: To identify intimate partner violence (IPV)-related injury patterns of U.S. patients of three age groups: <18 years (adolescents), 18-25 years (emerging adults), and >25 years (adults). METHODS: We performed a nationally representative retrospective review of all patients presenting to U.S. Emergency Department for IPV-related injuries from 2005 through 2020. Demographics and injury patterns were calculated using statistical methods accounting for the weighted stratified data. Main outcomes were injury morphology, mechanism, severity, location, and temporal associations of IPV-related injuries among the three age groups. RESULTS: There was a higher proportion of female victims, sexual assault cases, and lower trunk injuries among adolescents compared to emerging adults and adults. There was increasing injury severity, fractures, and hospital admissions with increasing age. Adolescents experienced a greater prevalence of fractures of the head, neck, hands, fingers, and distal lower extremity, while trunk fractures increased with age. The peak prevalence of violence-related Emergency Department visits among adolescents was in June and September, with the peak day as Tuesday. DISCUSSION: Injurious forms of IPV are prevalent across all age groups, with sexual assault cases demonstrably higher among adolescents and increasing severity of injuries as victims age. Identification of age-specific injury patterns will aid health-care professionals and policymakers in developing targeted interventions for adolescents who experience IPV.

Changes in injury type among NBA athletes in response to the COVID-19 pandemic.

CONTEXT: The 2019-2020 NBA season was altered significantly by the COVID-19 pandemic with a midseason suspension of games, the NBA 'bubble' tournament, and a shortened offseason. Concerns were raised regarding player conditioning and the potential increased risk of injury due to the schedule changes. The purpose of this study was to determine the impact of the COVID-19 pandemic and associated schedule changes on NBA injuries. It was hypothesized that injury rates would be higher in the year following the pandemic and teams who participated in the bubble would have higher injury rates in the following season than non-bubble teams. Furthermore, the types of injuries would shift toward more severe injuries in the condensed 2019-20 season and the following 2020-21 season. DESIGN: Retrospective Cohort Study. METHODS: The NBA's public injury reports were queried to identify players listed on an injury report. Standardized injury events were calculated for four pre-COVID-19 seasons (2015-2019), the COVID-19 season (2019-2020), and the post-COVID-19 season (2020-2021). Injury characteristics including type and location were extracted for each year and differences within each period were calculated. RESULTS: When excluding injury events related to COVID-19 health and safety protocols, the overall injury events per 1000 exposures were not significantly different between time periods of pre-COVID-19, COVID-19, and post-COVID-19 seasons; (p = 0.199), and no difference was found in the rates of teams who participated in the bubble. Injuries, including soreness and strains, significantly decreased while fracture injuries significantly increased in the COVID-19 year. CONCLUSIONS: The COVID-19 pandemic led to an increased number of games missed, but no increase in injury rates when accounting for health and safety protocols. Additionally, bubble participation had no impact on injury rates. However, despite no changes in injury rates, the types of injuries changed with an increased proportion of severe injuries and decreased proportion of minor injuries.

Injury Pattern and Current Early Clinical Care of Pediatric Polytrauma Comparing Different Age Groups in a Level I Trauma Center.

Introduction: Pediatric polytrauma is a complex condition with unique characteristics and requirements for early clinical care. This study aimed to analyze the injury patterns, early clinical care, and outcomes of pediatric polytrauma patients in a Level I trauma center. The focus was on evaluation between different age groups and the recognition of injuries as potential factors influencing outcomes. Methods: A prospective cohort study model of pediatric polytrauma patients (ISS ≥ 16) was conducted over a 13-year period, stratified by age groups (Group A: 0-5 years; Group B: 6-10 years; Group C: 11-15 years; and Group D: 16-18 years). A comparison of the groups was conducted to examine variations in early clinical care, trauma mechanisms, distribution of affected body regions (as per AIS and ISS criteria), and trauma-related mortality. Additionally, factors contributing to mortality were evaluated. Results: The median age of patients was 16 years, with a male predominance (64.7%). The Injury Severity Score (ISS) varied across age groups, with no significant difference. The 30-day mortality rate was 19.0%, with no significant age-related differences. Trauma mechanisms varied across age groups, with motor vehicle accidents being the most common mechanism in all age groups except 0-5 years, where falls were prevalent. Analysis of injury patterns by AIS body regions indicated that head trauma was a significant predictor of mortality (Hazard Ratio 2.894, p < 0.001), while chest, abdominal, and extremity trauma showed no significant association with mortality. Multiple regression analysis identified the ISS and preclinical GCS as valid predictors of mortality (p < 0.001 and p = 0.006, respectively). Conclusions: While age-related differences in injury severity and clinical interventions were limited, head trauma emerged as a critical predictor of mortality. Early recognition and management of head injuries are crucial in improving outcomes. Additionally, the ISS and preclinical GCS were identified as valid predictors of mortality, emphasizing the importance of early assessment and resuscitation. A tailored approach to pediatric polytrauma care, considering both age and injury patterns, might contribute to survival benefits in this vulnerable population.

[Bicycle accidents in the course of time in Münster, Germany : Analysis of changes in bicycle accidents over the past 10 years]. / Münsteraner Fahrradunfälle im Wandel der Zeit : Analyse der Entwicklung der Fahrradunfälle in den letzten 10 Jahren.

BACKGROUND: Bicycles have been a popular means of transport for many years. Especially in times of increased climate discussion, the bicycle has moved further into focus as an environmentally friendly and cost-effective means of transport. Bike lanes and roads are becoming more crowded and new means of transport such as pedelecs or e­scooters are emerging. METHODS: A total of four studies by Münster University Hospital on bicycle accidents and the official accident statistics of the Münster police were compared. In the period from 2009 to 2019, three studies were conducted that considered all bicycle accidents and one study that only considered pedelec riders separately. RESULTS: The age distribution as well as main causes of accidents remained almost the same over the years. The number of pedelec accidents has increased. Pedelec riders have a higher average age and a higher proportion of intensive care stays; however, this cohort also has a high rate of helmet wearers. Overall, the willingness to wear a helmet seems to have increased. CONCLUSION: It should be considered that with increasing bicycle traffic, safety measures must be increased accordingly. In this respect, accident prevention should focus on three major areas, engineering, education and enforcement.

Analysis of female strangulation homicides in King County, Washington, from 1978 to 2022.

Asphyxia due to strangulation is an uncommon but important modality of homicide that tends to disproportionately involve female victims. The present study was designed to investigate the circumstances, motivations, and injuries associated with strangulation homicides of females and to measure trends in incidence over time. Electronic records of the King County Medical Examiner's Office in Seattle, Washington, were used to compile a data set of all homicides in King County from 1995 through 2022. A second data set of female homicides due to strangulation was constructed with additional records prior to 1995, supplemented with data abstracted from autopsy reports, and linked to the Washington Attorney General's Office Homicide Investigation Tracking System database. This comprehensive data set was used to analyze demographics, circumstances, motives, and injuries of female strangulation homicides from 1978 through 2016. The results found that, from 1995 through 2022, females accounted for 22.8% of 2394 homicides but 80.3% of strangulation homicides. The average annual rate of all strangulation homicides decreased until 2020. Mean ages of female decedents were 27.7 years in homicides associated with sexual assault, 36.8 years with domestic violence, and 63.9 years with robbery. Lethal assaults most often occurred in private homes, and perpetrators were usually well known to the victim. Injuries included petechiae in 83%; ligature marks in 20%; fingernail marks in 1.4%; hyoid fractures in 23%; and thyroid cartilage fractures in 31%. Fractures were more common in manual strangulation and in decedents of ages over 40 years.

Injury Patterns and Incidence in an Elite Youth Football Academy-A Prospective Cohort Study of 138 Male Athletes.

BACKGROUND: There is a lack of evidence regarding injury incidence in German elite youth football academies, and the risk of re-injury is unknown. Therefore, the objectives of this study were (1) to determine injury patterns and incidence in an elite youth football academy in Germany, (2) to monitor overuse-/trauma-related injuries over the course of the season, and (3) determine the risk of re-injury. METHODS: A prospective cohort study was conducted in the 2012/2013 season among 138 male players from an elite youth football academy in Germany. Injuries were recorded according to the consensus statement on injury definitions and data collection in studies of football injuries. Injury incidence was reported as the number of injuries per 1000 h of exposure and the number of injuries per squad season. RESULTS: A total of 109 injuries were reported, resulting in a cumulative time-loss of 2536 days. A squad of 25 players sustained 19.7 injuries per season, with an average of 23.3 days (15.7-30.9; 95% CI lower-upper) of absence per injury. Ligament sprains (28%), muscle strains (19%) and physeal injuries (12%) were the most common causes of time-loss. Physeal injuries were the most common severe type of injury (29%), with a mean time-loss of 29.7 days (18.2-41.2; 95% CI lower-upper). Re-injuries accounted for 3% of all injuries and resulted in significantly more time-loss than non-re-injuries (60 vs. 23 days; p = 0.01). CONCLUSION: In the youth academies studied, a team of 25 players sustained an average of 19.7 injuries per season, resulting in a cumulative time-loss of 459 days. Physeal injuries are a major contributor to severe injuries and therefore require special attention.

Recreational windsurfing-related acute injuries: a narrative review. Part 1: injury epidemiology and a proposal for standardized injury definitions.

Objective: The purpose of this review was to identify the epidemiology of, and develop standardized injury definitions for, acute injuries among recreational windsurfers. Methods: A literature search was conducted from the PubMed and Google Scholar databases through February 28, 2023, using relevant keywords with Boolean operators, such as "windsurfing" AND "epidemiology" AND "risk factors." Only peer-reviewed, relevant windsurfing-related injury articles were included. Results: A wide range of acute injuries, from minor, moderate, severe, to catastrophic, were reported. Injury rates, frequency of anatomical distributions, existing and potential risk factors, the proposed standardization definitions of behaviour types, skill levels, general windsurfing-related injuries, and injury severity classifications and levels for windsurfing epidemiology were identified and tabled. Conclusions: There is inconsistency in the epidemiological methods and definitions of windsurfing research. The injury rates remain difficult to compare among the identified studies. Future in-depth windsurfing-related injury studies should focus on prospective designs using standardized injury definitions.

Objectif: Le but de cette étude était d'identifier l'épidémiologie des blessures aiguës chez les véliplanchistes amateurs et d'élaborer des définitions normalisées de ces blessures. Méthodologie: Une recherche documentaire a été effectuée dans les bases de données PubMed et Google Scholar jusqu'au 28 février 2023, en utilisant des mots clés pertinents avec des opérateurs booléens, tels que "windsurfing" AND "epidemiology" AND "risk factors" (planche à voile ET épidémiologie ET facteurs de risque). Seuls les articles pertinents sur les blessures liées à la planche à voile, examinés par des pairs, ont été retenus. Résultats: Un large éventail de blessures aiguës, allant de mineures à catastrophiques, a été rapporté. Les taux de blessures, la fréquence des répartitions anatomiques, les facteurs de risque existants et potentiels, les définitions de normalisation proposées pour les types de comportement, les niveaux de compétence, les blessures générales liées à la planche à voile, ainsi que les classifications et les niveaux de gravité des blessures pour l'épidémiologie de la planche à voile ont été déterminés et présentés. Conclusions: Les méthodes et définitions épidémiologiques de la recherche sur la planche à voile manquent de cohérence. Les taux de blessures restent difficiles à comparer entre les études retenues. Les futures études approfondies sur les blessures liées à la planche à voile devraient se pencher sur des modèles prospectifs utilisant des définitions de blessures standardisées.

Evaluating Changes in Trauma Epidemiology during the COVID-19 Lockdown: Insights and Implications for Public Health and Disaster Preparedness.

The COVID-19 pandemic demanded changes in healthcare systems worldwide. The lockdown brought about difficulties in healthcare access. However, trauma still required further attention considering its modifications. The presented study aims to investigate the variances in epidemiological patterns of trauma during the lockdown and the previous year, with a view to better understand the modifications in healthcare provision. The authors analyzed data from the first lockdown in 2020 (12 March-30 May) and the same period in 2019 from 35 hospitals in Lublin Province. A total of 10,806 patients in 2019 and 5212 patients in 2020 were included in the research. The uncovered changes adhered to the total admissions and mortality rate, the frequency of injuries in particular body regions, and injury mechanisms. The lockdown period resulted in a reduction in trauma, requiring an altered approach to healthcare provision. Our research indicates that the altered approach facilitated during such periods is essential for delivering tailored help to trauma patients.

Mechanisms and weapons in physical elder abuse injuries: Findings from legally adjudicated cases.

INTRODUCTION: Elder abuse is common, but many characteristics have not been well-described, including injury mechanisms and weapons in physical abuse. Better understanding of these may improve identification of elder abuse among purportedly unintentional injuries. Our goal was to describe mechanisms of injury and weapons used and their relation to injury patterns. METHODS: We partnered with District Attorney's offices in 3 counties and systematically examined medical, police, and legal records from 164 successfully prosecuted physical abuse cases of victims aged ≥60 from 2001 to 2014. RESULTS: Victims sustained 680 injuries (mean 4.1, median 2.0, range 1-35). Most common mechanisms were: blunt assault with hand/fist (44.5%), push/shove, fall during altercation (27.4%), and blunt assault with object (15.2%). Perpetrators more commonly used body parts as weapons (72.6%) than objects (23.8%). Most commonly used body parts were: open hands (55.5% of victims sustaining injuries from body parts), closed fists (53.8%), and feet (16.0%). Most commonly used objects were: knives (35.9% of victims sustaining injuries from objects) and telephones (10.3%). The most frequent mechanism/injury location pair was maxillofacial/dental/neck injury by blunt assault with hand/fist (20.0% of all injuries). The most frequent mechanism/injury type pair was bruising by blunt assault with hand/fist (15.1% of all injuries). Blunt assault with hand/fist injury was positively associated with victim female sex (OR: 2.27, CI: [1.08 - 4.95]; p = 0.031), while blunt assault with object mechanisms was inversely associated with victim female sex (OR: 0.32, CI: [0.12 - 0.81]; p = 0.017). CONCLUSION: Physical elder abuse victims are more commonly assaulted with an abuser's body part than an object, and the mechanisms and weapons used impact patterns of injury.

Safety Factors and Patterns of Bicycle Trauma in a Tertiary Level 1 Trauma Center in Boston, Massachusetts: A Retrospective Review and Survey Study.

Objectives: Increasing bicycle ridership is accompanied by ongoing bicycle-related accidents in many urban cities. There is a need for improved understanding of patterns and risks of urban bicycle usage. We describe the injuries and outcomes of bicycle-related trauma in Boston, Massachusetts, and determine accident-related factors and behaviors associated with injury severity. Methods: We conducted a retrospective review via chart review of 313 bicycle-related injuries presenting to a Level 1 trauma center in Boston, Massachusetts. These patients were also surveyed regarding accident-related factors, personal safety practices, and road and environmental conditions during the accident. Results: Over half of all cyclists biked for commuting and recreational purposes (54%), used a road without a bike lane (58%), and a majority wore a helmet (91%). The most common injury pattern involved the extremities (42%) followed by head injuries (13%). Bicycling for commuting rather than recreation, cycling on a road with a dedicated bicycle lane, the absence of gravel or sand, and use of bicycle lights were all factors associated with decreased injury severity (p<0.05). After any bicycle injury, the number of miles cycled decreased significantly regardless of cycling purpose. Conclusion: Our results suggest that physical separation of cyclists from motor vehicles via bicycle lanes, regular cleaning of these lanes, and usage of bicycle lights are modifiable factors protective against injury and injury severity. Safe bicycling practices and understanding of factors involved in bicycle-related trauma can reduce injury severity and guide effective public health initiatives and urban planning.

Changes in injury patterns, injury severity and hospital mortality in motorized vehicle accidents: a retrospective, cross-sectional, multicenter study with 19,225 cases derived from the TraumaRegister DGU®.

PURPOSE: In the last 20 years, the number of fatalities due to road traffic accidents (RTA) in Germany has steadily decreased from 7503 to 2724 per year. Due to legal regulations, educational measures and the continuous development of safety technology the number of severe traumatic injuries and injury patterns are most likely to change. The aim of the study was to analyse severely injured motorcyclists (MC) and car occupants (CO) that were involved in RTAs in the last 15 years and investigate the development and changes of injury patterns, injury severity and hospital mortality. METHODS: We retrospectively evaluated data from the TraumaRegister DGU® (TR-DGU) considering all RTA-related injured MCs and COs (n = 19,225) that were registered in the TR-DGU from 2006 to 2020 with a primary admission to a trauma center with continuous participation (14 of 15 years) in the TR-DGU, an Injury Severity Score (ISS) ≥ 16 and aged between 16 and 79 years. The observation period was divided into three 5-year interval subgroups for further analysis. RESULTS: The mean age increased by 6.9 years and the ratio of severely injured MCs to COs changed from 1:1.92 to 1:1.45. COs were in 65.8% male and more often severely injured in the age groups under 30, while the majority of severely injured MCs were in the age group around 50 years and in 90.1% male. The ISS (- 3.1 points) as well as the mortality of both groups (CO: 14.4% vs. 11.8%; MC: 13.2% vs. 10.2%) steadily decreased over time. Nevertheless, the standardized mortality ratio (SMR) hardly changed and stayed < 1. Regarding the injury patterns, the greatest decline of injuries with AIS 3 + were to the head (CO: - 11.3%; MC: - 7.1%), in addition, a decrease of injuries to extremities (CO: - 1.5%; MC: - 3.3%), to the abdomen (CO: - 2.6%; MC: - 3.6%), to the pelvis in COs (- 4.7%) and to the spine (CO: + 0.1%; MC: - 2.4%) were observed. Thoracic injuries increased in both groups (CO: + 1.6%; MC: + 3.2%) and, furthermore, pelvic injuries in MCs (+ 1.7%). Another finding was the increase of the utilization of whole body CTs from 76.6 to 95.15%. CONCLUSION: The severity of injuries and their incidence, especially head injuries, have decreased over the years and seem to contribute to a decreasing hospital mortality of polytraumatized MCs and COs injured in traffic accidents. Young drivers and an increasing number of seniors are the age groups at risk and require special attention and treatment.

Epidemiology of Football Injuries of the German Bundesliga: A Media-Based, Prospective Analysis over 7 Consecutive Seasons.

BACKGROUND: This study describes the implementation of a standardised, prospective injury database covering the entire 1st male German football league ("Bundesliga") based on publicly available media data. For the first time, various media sources were used simultaneously as the external validity of media-generated data was low in the past compared to data obtained by way of the "gold standard", i.e. by the teams' medical staffs. METHODS: The study covers 7 consecutive seasons (2014/15-2020/21). The primary data source was the online version of the sport-specific journal "kicker Sportmagazin™" complemented by further publicly available media data. Injury data collection followed the Fuller consensus statement on football injury studies. RESULTS: During the 7 seasons, 6653 injuries occurred, thereof 3821 in training and 2832 in matches. The injury incidence rates (IRs) per 1000 football hours were 5.5 [95% CI 5.3-5.6], 25.9 [25.0-26.9] per 1000 match, and 3.4 [3.3-3.6] per 1000 training hours. Twenty-four per cent of the injuries (n = 1569, IR 1.3 [1.2-1.4]) affected the thigh, 15% (n = 1023, IR 0.8 [0.8-0.9]) the knee, and 13% (n = 856, IR 0.7 [0.7-0.8]) the ankle. Muscle/tendon injuries contributed 49% (n = 3288, IR 2.7 [2.6-2.8]), joint/ligament injuries 17% (n = 1152, IR 0.9 [0.9-1.0]), and contusions 13% (n = 855, IR 0.7 [0.7-0.8]). Compared to studies using injury reports from the clubs' medical staff, media data revealed similar proportional distributions of the injuries, but the IRs tended towards the lower end. Obtaining specific locations or diagnosis especially with regard to minor injuries is difficult. CONCLUSIONS: Media data are convenient for investigating the quantity of injuries of an entire league, for identifying injuries for further subanalysis, and for analysing complex injuries. Future studies will focus on the identification of inter- and intraseasonal trends, players' individual injury histories, and risk factors for subsequent injuries. Furthermore, these data will be used in a complex system approach for developing a clinical decision support system, e.g. for return to play decisions.

E-scooter and E-bike injury pattern profile in an inner-city trauma center in upper Manhattan.

BACKGROUND: Electric bikes and scooters are becoming popular means of short-distance transportation in major cities. Regulations for safe riding established by ride-sharing companies and local governments have not been effectively implemented. Inner-city hospitals are at the frontline of receiving traumas related to e-bikes and e-scooters and are receiving an increasing number of injuries. The works of literature reporting these injuries are limited. METHOD: This study reviewed all the trauma activations at a major trauma center in NYC from 04/2019 to 08/2021. Patients with e-bike and e-scooter injuries were included in the study. Socio-demographics of riders, passengers, injury patterns, and outcomes were reviewed. Logistics regression was used to analyze the factors associated with Injury Severity Scale. RESULTS: We reviewed 1979 patient charts of trauma activation in the Emergency Department. We included 88 scooters, 24 E-bike, and 5 nonrider scooter injuries. 91% were male and 9% were Female victims. The majority were African American patients (34%) and Hispanic patients (46%). 87% belonged to the 18-50 years age group, and 13% were above 50 years and below 18 years were excluded from the study. 36% of victims were under the influence of drugs or alcohol and only 25% of riders wore helmets. 58% of patients were discharged from the ED, 42% required hospital admission, and 14% required ICU care. Odds of non-mild injury (moderate to critical injury) in comparison to mild injury were significantly greater with increasing age. CONCLUSIONS: The use of e-bikes and e-scooters is increasing as a means of affordable short-distance transportation but with evidence of significant injuries with varying severity. These findings suggest a need to review public policy regarding e-bike and electric scooter use regulations for the safety of riders and pedestrians; Driving While Intoxicated (DWI) law enforcement, mandatory helmet, education, speed control, creation of special lanes, and no car zones.

Epidemiology and outcomes of traumatic chest injuries in children: a nationwide study in the Netherlands.

Thoracic injuries are infrequent among children, but still represent one of the leading causes of pediatric mortality. Studies on pediatric chest trauma are dated, and little is known of outcomes in different age categories. This study aims to provide an overview of the incidence, injury patterns, and in-hospital outcomes of children with chest injuries. A nationwide retrospective cohort study was performed on children with chest injuries, using data from the Dutch Trauma Registry. All patients admitted to a Dutch hospital between January 2015 and December 2019, with an abbreviated injury scale score of the thorax between 2 and 6, or at least one rib fracture, were included. Incidence rates of chest injuries were calculated with demographic data from the Dutch Population Register. Injury patterns and in-hospital outcomes were assessed in children in four different age groups. A total of 66,751 children were admitted to a hospital in the Netherlands after a trauma between January 2015 and December 2019, of whom 733 (1.1%) sustained chest injuries accounting for an incidence rate of 4.9 per 100,000 person-years. The median age was 10.9 (interquartile range (IQR) 5.7-14.2) years and 62.6% were male. In a quarter of all children, the mechanisms were not further specified or unknown. Most prevalent injuries were lung contusions (40.5%) and rib fractures (27.6%). The median hospital length of stay was 3 (IQR 2-8) days, with 43.4% being admitted to the intensive care unit. The 30-day mortality rate was 6.8%. CONCLUSION: Pediatric chest trauma still results in substantial adverse outcomes, such as disability and mortality. Lung contusions may be inflicted without fracturing the ribs. This contrasting injury pattern compared to adults underlines the importance of evaluating children with chest injuries with additional caution. WHAT IS KNOWN: • Chest injuries are rare among children, but represent one of the leading causes of pediatric mortality. • Children show distinct injury patterns in which pulmonary contusions are more prevalent than rib fractures. WHAT IS NEW: • The proportion of chest injuries among pediatric trauma patients is currently lower than reported in previous literature, but still leads to substantial adverse outcomes, such as disabilities and death. • The incidence of rib fractures gradually increases with age and in particular around puberty when ossification of the ribs becomes completed. The incidence of rib fractures among infants is remarkably high, which is strongly suggestive for nonaccidental trauma.

Electric scooter-related accidents: a possible protective effect of helmet use on the head injury severity.

Despite electric scooter use has proliferated in Italy since 2019, actionable data regarding injury incidence and patterns associated with electric scooter accidents are limited. This study aims at analyzing the rate, clinical, and demographic features of electric scooter accidents accessed to the Emergency Department (ED) of Fondazione Policlinico Universitario A. Gemelli IRCSS (Rome, Italy). This retrospective study included all patients older than 18 years riding an electric scooter in the ED from June 2019 to April 2022. Personal data, injury circumstances, helmet use, and health data were collected. Abbreviated Injury Scale (AIS) codes of all diagnoses were recorded, and the Injury Severity Score (ISS) was calculated for each patient. The analysis includes 92 patients admitted to the ED due to an e-scooter accident during the study period, with an increase in years. Thirty-two patients presented bone fractures especially concerning the extremities and the face districts. The median Injury Severity Score in the study cohort was 3, with the highest AIS represented by AIS Pelvic-Extremity and AIS External. Moreover, statistical significance was found between AIS Head-Neck and severity of trauma. E-scooters have become a familiar sight in cities worldwide recently, with many new companies renting them for use. But their arrival has also brought new safety concerns. Although most injuries reported are minor, the meager rate of helmet use is critical. Implementing compulsory helmet use for electric scooters for all ages could be a protective factor for being patient with head trauma on urban streets.

The Impact of the COVID-19 Pandemic on Injury Patterns in Inpatient and Outpatient Orthopaedic Trauma.

The effect of banning of nonessential services during the novel coronavirus disease 2019 (COVID-19) pandemic led to a perceived change in the volume of trauma cases and injury patterns. Literature indicates trends toward less trauma overall, with a decrease in outdoor, sporting, and motor vehicle injuries. However, studies focusing on outpatient orthopaedic trauma are less common. The main aim of this study was to assess the effect of COVID-19 pandemic on differences in inpatient and outpatient injury patterns and mechanisms. Patients requiring orthopaedic inpatient admission to Mater Dei Hospital, Malta, were analyzed between March 15 and June 17 between 2019 and 2021. For outpatients, all newly referred patients seen at the fresh trauma clinic (FTC) on the first 5 clinic days of each month from April to June between 2019 and 2021 were assessed. There were a total of 503, 362, and 603 hospital admissions during the data collection period from 2019, 2020 and 2021, respectively. There was a decrease in elbow ( p = 0.015) and pelvis ( p = 0.038) pathology since COVID-19 pandemic. In contrast, there was an increase in shoulder injuries ( p = 0.036) and lacerated wounds ( p = 0.012) in 2021. The most frequent mechanisms of injury for inpatients were low impact falls, and fall from heights greater than 1 m. Machine-related injuries ( p = 0.002), blunt trauma ( p = 0.004), and twisting injuries ( p = 0.029) increased in 2021. In the outpatient setting, there were a total of 367, 232, and 299 new referrals in 2019, 2020, and 2021, respectively. Injury patterns in this cohort were similar throughout, except for a significant increase in shoulder injuries during 2020 ( p = 0.009). There appears to be some minor variation in injury mechanisms due to lifestyle changes; however, most injury patterns have remained fairly constant. Further research should focus on the use of public awareness campaigns to decrease home-related trauma during enforced periods of lockdown.

Drug-Induced Liver Injury.

Drug-induced liver injury (DILI) is a spectrum of liver injuries that can be classified by phenotype and injury patterns. Some injury patterns can be predicted in a number of drugs that are commonly used in practice, but idiosyncratic reactions are unpredictable and are not dose related. There are diagnostic criteria to assist in the classification of DILI phenotype as well as therapeutic interventions to ensure maximal support to the patient affected with DILI to include referral for liver transplantation in some cases.

Is the Use of Segways or E-Scooters in Urban Areas a Potential Health Risk? A Comparison of Trauma Consequences.

Background and objectives: Electromobility has become increasingly popular. In 2001, Segway personal transporters (Segway) were established for tourists, and e-scooters have been in use since their approval in 2019. The aim of this study was to analyze and compare the types of injuries directly related to the use of Segways and e-scooters, respectively, in a German city and to phrase potential safety advice. Materials and Methods: All patients presenting to our emergency department after Segway incidents were retrospectively analyzed and compared with the prospectively collected cohort of patients following e-scooter incidents. Presented injuries were analyzed by body region and injury severity score (ISS). Epidemiological data were collected. Results: Overall, 171 patients were enrolled. The Segway group included 56 patients (mean age 48 years), and the e-scooter group consisted of 115 patients (mean age 33.9 years). Head injuries (HI) occurred in 34% in the Segway group compared to 52% in the e-scooter group. The ISS was approximately equal for both groups (mean ISS Segway group: 6.9/e-scooter group: 5.6). Conclusions: Since the e-scooter group presented a high number of HI along with a higher likelihood and greater severity of HI, mandatory use of helmets is suggested.
