Abstract
Bicycles are employed as means of transportation across various age groups, from young students to the elderly, for work, education, health, and leisure trips. Despite not achieving high speeds, bicyclists remain vulnerable to severe and even fatal injuries when they are involved in traffic accidents. Although the rising awareness of ecological issues and traffic law enforcement mean that cyclists are increasingly susceptible to road traffic crashes and injuries. Injuries resulting from a traffic accident involving cyclists can show distinct and specific characteristics depending on the manner of occurrence. The aim of this study is to provide a systematic review of the literature on injuries sustained in cyclists involved in road accidents describing and analysing elements useful for forensic assessment. The literature search was performed using PubMed, Scopus, and Web of Science from January 1970 to March 2023. Eligible studies have investigated issues of interest to forensic medicine about traffic accidents involving bicycles. A total of 128 studies satisfied the inclusion criteria and were categorized and analyzed according to the anatomical regions of the body affected (head, neck, thoraco-abdominal, and limb injuries), and the assessment of lesions in reconstruction of the bicycle accident was examined and discussed. This review highlights that injuries resulting from a traffic accident involving cyclists can show distinct and specific characteristics depending on the manner of occurrence and the energy levels involved in the crash. The assessment of injuries offers valuable insights that integrated with circumstantial and engineering data perform the reconstruction of accident dynamics.

Abstract
INTRODUCTION Outdoor activities offer physical and mental health benefits. However, incidents can occur requiring ambulance transport to hospital. This study aimed to describe the epidemiology and severity of traumatic and medical incidents for mountain bikers and hikers transported by ambulance within Western Australia. METHODS This was a retrospective cohort study of ambulance-transported mountain bikers and hikers within Western Australia from 2015 to 2020. Data were extracted from ambulance electronic patient care records. Multivariable analyses were undertaken to identify variables associated with higher patient severity based on the National Early Warning Score 2 (NEWS2). RESULTS A total of 610 patients required ambulance transport to hospital while mountain biking (n=329; 54%) or hiking (n = 281; 46%). Median age of mountain bikers and hikers was 38 (24-48) y and 49 (32-63) y, respectively. Paramedics reported a fracture in 92 (28%) mountain bikers and 78 (28%) hikers. The predominant injury locations for mountain bikers were upper limbs and for hikers, lower limbs. Cases were trauma related in 92% of mountain bikers and 55% of hikers. A significant association (P<0.001) between the etiology of the ambulance callout and patient severity was found. In trauma etiology cases, the frequency of medium-risk+ NEWS2 severity was 21.4%. In medical cases, the frequency of medium-risk+ severity was 40.8%. CONCLUSION Both mountain bikers and hikers experienced incidents requiring ambulance transport to hospital. Incidents of a medical etiology had a higher clinical risk, as determined by the NEWS2 scores, regardless of activity being undertaken.

Abstract
Woyke, Simon, Anja Hütter, Christopher Rugg, Willi Tröger, Bernd Wallner, Mathias Ströhle, and Peter Paal. Sex differences in mountain bike accidents in Austria from 2006 to 2018: a retrospective analysis. High Alt Med Biol. 25:89-93, 2024. Introduction: Mountain biking is becoming increasingly popular, and mountain bike (MTB) accidents are on the rise. The aim of this study was to assess sex differences in mountain biking accidents in the Austrian Alps. Methods: This retrospective study includes all MTB accidents in Austria from 2006 to 2018. Data were collected by Alpine Police officers and recorded in a national digital registry. Results: The accidents involved 5,095 mountain bikers (81% men and 19% women). The number of MTB accidents rose markedly from 208 in 2006 to 725 in 2018. Men wore a helmet more often than did women (95% vs. 92%; p = 0.001). The most common injury category was "wound/bleeding" for both sexes (men 40% and women 41%). Women were more frequently transported by helicopter or terrestrially (p > 0.001). Conclusion: In the Austrian Alps, the number of MTB accidents more than tripled between 2006 and 2018. Women were involved in only one fifth of all accidents. Sex differences in MTB accidents include (1) women wearing helmets less often, (2) women being less frequently injured, (3) women suffering fewer serious injuries, and (4) women being more frequently transported by helicopter or terrestrially, while men more often did not require transportation.

Abstract
Mountain biking is growing in participation but carries risk for severe injury and burden on health systems. Little is known about the impact of these injuries on emergency medical services, definitive healthcare, and factors contributing to accidents. This review aimed to determine the health service impacts of severe mountain bike trauma and risk factors, with a view to understanding critical gaps and needs. A systematic online search was conducted using the databases PubMed and MEDLINE complete and grey literature relating to mountain bike injury since the databases' inception to July 2023. The results show that although mountain biking has relatively high injury rates that are increasing, the impacts on health services were rarely documented, with some evidence indicating that even small increases in injuries from race events can overwhelm local health services. Severe injuries were more common in downhill disciplines. However, the definitions of what constitutes severe injury were variable. Severe injuries were more common in downhill disciplines, influenced by the rider skill level, demographics, participation in competitive events, trail design, environmental factors, and healthcare availability. Further research in these areas is needed, along with the more consistent reporting of injury severity.

Abstract
Objective To describe the types of analgesic medications administered to patients who were attended by ambulance on recreational trails while mountain biking or hiking and report on the reduction in pain by these agents. Methods This is a retrospective cohort study of patients attended by ambulance (2015-2021) after mountain biking or hiking, on Western Australia (WA) trails. All data were extracted from electronic patient care records created by ambulance personnel who attended the patient. We compared patient and case characteristics between mountain bikers and hikers and the reduction in pain scores achieved by different analgesics. Results A total of 717 patients were included. Paramedics reported traumatic aetiology for mountain bikers in 92 % of cases and hikers in 58 % of cases. A pain score out of 10 was recorded for 538 (75 %) patients. The median (inter-quartile range) initial pain score was 6 (2-8) and the median final pain score was 3 (1-5). Around 48 % of these 538 patients reported ≥25 % reduction in their pain score. A reduction of ≥25 % in their pain score was greatest in those patients who received intravenous fentanyl (81 %), followed by patients administered multiple analgesics (72 %) and methoxyflurane only (52 %). Even 37 % of 134 patients who received no analgesia still reported ≥25 % reduction in their pain score by hospital arrival. Conclusion Trauma was the most common reason mountain bikers and hikers on trails called an ambulance and a large proportion of these patients were in pain on ambulance arrival. Further work assessing the effectiveness of safe, non-opioid analgesics, additional to methoxyflurane, is needed to ensure non-registered practitioners such as first aid providers and event medical teams can offer suitable safe analgesics to these patients. Additionally, among patients given no pharmacological analgesic agent, almost half still achieved a >25 % reduction in their pain scores which reiterates the importance of non-pharmacological pain reduction strategies.

Abstract
Dental anterior fractures are common injuries, especially in those who practice extreme sports. This report describes a 25-year-old Bolivian patient who attended our private dental clinic in La Paz, Bolivia after experiencing an accident during downhill mountain biking. An intraoral examination revealed a fracture line on the buccal side in the middle third of the coronal portion of the right central maxillary incisor which extended towards the proximal and lingual sides. Multidisciplinary treatment, including crown lengthening, osteotomy, root canal treatment, fiberglass post insertion, and reattachment of the fracture segment was performed. A follow-up examination at 10 months later revealed that the tooth was completely reestablished both functionally and esthetically and that there was no periapical pathosis or discomfort. This outcome suggests that if a patient seeks a dental consultation soon after a complex crown-root fracture has occurred, and if the broken tooth segment is available, then reattachment offers an economical and simple treatment option which will allow immediate restoration of functionality and esthetic standards. Continued follow-up should form part of such a treatment plan to allow long-term pulp vitality and periodontal health status to be monitored.

Abstract
Cycling is an increasingly popular activity which is widely supported by health advocates. In the last year, more than a third of Australians used a bike [1]. While road cycling remains popular, participation in off-road recreational cycling, including mountain biking, bicycle moto cross (BMX) riding, and outdoor leisure cycling, is increasing and this is associated with an increase in the number and cost of cycling injuries [2-5]. The aim of this study was to describe and compare contemporary patterns of cycling fracture requiring hospitalisation as a function of cycling mode in the Australian Capital Territory region. This retrospective analysis of cycling-related-fracture hospitalisations in the ACT region described data recorded between July 2012 and December 2019. Logistic regression models were used to calculate probabilities of sustaining a fracture at different sites for each of the cycling modes (on-road, mountain, BMX, leisure, unspecified). These likelihoods were then compared against the on-road fracture profile. Cycling-related-fracture hospitalisations increased by 32% in the seven years analysed. Of all fracture admissions, 442 (33%) were on-road, 658 (49%) off-road, and 242 (18%) unknown. The majority were male (79%), median age 37 (IQR 16, 52). Median length of stay was two days. The number of fractures per admission ranged from one to thirteen with a median of one. Wrist, clavicle, ribs, and skull were the four most frequent fracture sites for all cycling modes. Fracture profiles of on- and off-road accidents were similar, with the exception of wrist fractures which were more likely in off-road (OR 1.96, p < 0.01) and unspecified cycling accidents (OR 5.07, p < 0.01). Skull fractures comprised 19% of all BMX-related fractures. More than half of all fracture-related admissions required surgery. With increasing support for sustainable and healthy transport and recreation activities, the fracture profiles of different cycling modes must first be assessed in order to inform strategies to reduce and manage this injury burden.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12281. [PMID: 36231582 PMCID: PMC9566347 DOI: 10.3390/ijerph191912281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/08/2022] [Accepted: 09/09/2022] [Indexed: 06/16/2023]
Abstract
INTRODUCTION Downhill mountain biking (DHI) is a form of cycling and does not currently have a specific sports-related concussion (SRC) assessment. OBJECTIVE To review the extent, range and nature of research investigating SRC in DMB, provide a summary of key literature findings relating to its identification and management, and then develop a SRC protocol specific to DMB. DESIGN Scoping review as per recognised methods. SETTING Literature-based. The following databases were searched: MEDLINE, EMBASE, Scopus and Web of Science, with no restrictions on date. Results were limited to the English language. PARTICIPANTS Six articles were included in the review from 64 identified articles. The article had to specifically include an analysis of adult downhill riders for inclusion. OUTCOME MEASURES Study type, study group (amateur/professional), concussion incidence, concussion assessment and recommendations. MAIN RESULTS Concussion incidence was identified as between 5-23%. No study outlined a trackside assessment of cyclists or a protocol for return to play where SRC was identified. Several authors identified that riders often continued to participate despite the presence of a concussion. No sport-specific SRC assessment was determined for DHI, and a SRC assessment was therefore developed. CONCLUSIONS This review illustrates the lack of studies and formal protocol in SRC assessment for DHI. In light of this, we propose a three-stage framework specific to the sport to best identify a concussion and act where appropriate while minimising disruption to competition. This framework involves assessing the cyclist on the 'sideline', a second assessment post-event in the medical room and a third assessment the following day. A SRC consensus meeting specific for DHI is suggested with an identified need for updated guidance from UCI, requiring possible rule changes for the sport.

Abstract
Despite recreational mountain-biking's growing popularity worldwide, the literature on mortality in this leisure sporting activity is scarce. Therefore, the aim of the present study was to investigate the characteristics of fatal accidents as well as resulting dead victims during recreational mountain-biking in the Austrian Alps over the past 16 years. For this purpose, a retrospective study based on Austrian institutional documentation from 2006 to 2021 was conducted. In total, 97 fatalities (1 woman) with a mean age of 55.6 ± 13.9 years were recorded by the Austrian Alpine Police. Of those, 54.6% died due to a non-traumatic (mostly cardio-vascular) and 41.2% due to a traumatic event. Mountain-bikers fatally accidented for non-traumatic reasons frequently belonged to older age classes (p = 0.05) and mostly (73.6%) died during the ascent, whereas traumatic events mainly (70.0%) happened during the descent (p < 0.001). Throughout the examined period, the absolute number of fatalities slightly increased, whereas the mortality index (proportion of deaths/accidented victims) did not (mean value: 1.34 ± 0.56%). Factors such as male sex in general, above average age and uphill riding for non-traumatic accidents, as well as downhill riding for traumatic events, seem to be associated with fatalities during recreational mountain-biking in the Austrian Alps. These results should be considered for future preventive strategies in recreational mountain-biking.

Abstract
Introduction Summer alpine sports, including mountain biking, hiking and airborne pursuits, have experienced a recent surge in popularity. Accordingly, trauma associated with these activities has increased. There is a scarcity of literature exploring clinical aspects surrounding injuries. Specifically, no single article provides a general overview, as individual studies tend to focus on one particular sport. In the present study, we performed a systematic literature review to summarize existing knowledge and explore the potential for prevention and clinical decision making in this group. Method Literature searches were performed using the PubMed and Scopus database for the most commonly ventured sports associated with injury: mountain biking, climbing, airborne sports, paragliding, and base jumping. From this search, studies were identified for qualitative and quantitative analyses. These searches were done according to PRISMA guidelines for systematic reviews. Studies were then analyzed regarding epidemiology of injuries, relevant anatomical considerations and prevention strategies were discussed. Results A broad spectrum of injury sites and mechanisms are seen in mountain biking, climbing or airborne sports. Mountain biking related injuries commonly involve the upper extremity, with fractures of the clavicle being the most common injury, followed by fractures of the hand and wrist. Scaphoid fractures remain of paramount importance in a differential diagnosis, given their often subtle clinical and radiological appearance. Paragliding, skydiving, and base jumping particularly affect transition areas of the spine, such as the thoracolumbar and the spinopelvic regions. Lower limb injuries were seen in equal frequency to spinal injuries. Regarding relative risk, mountain biking has the lowest risk for injuries, followed by climbing and airborne sports. Male alpinists are reported to be more susceptible to injuries than female alpinists. Generally, the literature surrounding hiking and water-related mountain sports is insufficient, and further work is required to elucidate injury mechanisms and effective preventative measures. A helmet seems to decrease the likelihood of face and head injuries in mountain sports and be a meaningful preventive measurement.

Chung VWJ, Dias L, Booth G, Cripton PA. Incorporating neck biomechanics in helmet testing: Evaluation of commercially available WaveCel helmets. Clin Biomech (Bristol, Avon) 2022; 94:105628. [PMID: 35358794 DOI: 10.1016/j.clinbiomech.2022.105628] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 12/15/2021] [Accepted: 03/15/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Cycling helmets often incorporate elements aimed to dissipate rotational energies, which is widely acknowledged to play a key role in concussion mechanics. In this study, we investigated the mechanics of an oblique helmet test protocol that induced helmet rotation while using it to evaluate the effectiveness of three helmet models: two standard expanded polystyrene helmets and a commercially-available helmet equipped with a liner designed to mitigate linear and rotational energies. METHODS Helmets equipped with WaveCel were tested against two expanded polystyrene helmet models through guided drops using a Hybrid III (HIII) head-and-neck surrogate. The three helmet models were tested across four impact conditions (n = 5) of different speeds and impact surface angles. FINDINGS Across all tests, a similar sequence of head motion was observed - first a flexion phase followed by an extension phase. The extension phase lacked evidence of biofidelity and was likely attributable to the energy stored in the neckform during the flexion phase; it was therefore neglected from analysis. Results showed WaveCel reduced the probability of AIS2 head injury across all tests (3 to 27% reductions in 4.8 m/s impacts; 36 to 37% reductions in 6.2 m/s impacts). INTERPRETATION The two-phased response of the HIII suggests that boundary condition selection can influence results and should thus be reported in studies using similar methods. While this protocol involved both axial and tangential impact components and were thus representative of real-world collisions, the efficacy of WaveCel should be further investigated through additional laboratory studies and tracking real-world cycling injury statistics.

Abstract
ABSTRACT A web-based injury surveillance system was implemented through a collaboration between University of Utah researchers and the National Interscholastic Cycling Association (NICA) to better understand injury characteristics in mountain biking. Data were collected from NICA leagues during the 2018 and 2019 seasons. Injuries were tracked in 41,327 student-athlete-years, identifying 1750 unique injuries during 1155 injury events. Rider-dependent and rider-independent variables were analyzed. The most commonly reported injuries were concussion (23.6%), injuries to the wrist/hand (22.3%), and shoulder (15.6%). Half of all injury events occurred on downhills. Men and women reported similar yet significantly different injury rates (2.69% and 3.21%, respectively; P = 0.009). Women sustained more lower-limb injuries (37.8% vs 28.3%; P = 0.003). Nearly 50% of crashes resulted in an emergency room visit. Youth mountain bike racing is a rapidly growing sport. Acute traumatic injuries are common. Injury surveillance system data are now being used to inform injury prevention strategies and direct future research.

Abstract
OBJECTIVES The popularity of mountain biking (MTB) in the United States has risen in recent years. We sought to identify the prevalence and distribution of MTB associated head and neck injuries presenting to emergency departments across the U.S. and identify risk factors for hospital admission in this patient population. METHODS The National Electronic Injury Surveillance System (NEISS) was queried for MTB related injuries of the head and neck from 2009 to 2018, with analysis for incidence, age, gender, anatomic site, and diagnoses. RESULTS A total of 486 cases were identified, corresponding to an estimated 18 952 head and neck MTB related ED visits. Patients were predominantly male (80.7%) and white (69.8%) with a median age of 35 years (interquartile range, 21-46 years). A majority (88.4%) of patients were released from the ED, but a significant proportion of patients were admitted (9.2%) or transferred (1.2%). The most common facial fractures were facial/not specified (35%), nasal bone (29%), mandible (15%), orbit (12%), and zygomaxillary complex (9%). The greatest predictors of hospital admission/transfer were injury to the mouth or neck and avulsion-type injury (P < .001). CONCLUSIONS MTB results in a significant number of traumatic head and neck injuries nationwide. Patients are primarily adult, white males. The majority of injuries result in discharge from the ED, however a small amount of these patients experience significant morbidity necessitating hospital admission. Understanding the distribution of MTB head and neck injuries may aid in the clinical evaluation of these patients. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVES To describe the design and implementation of an injury surveillance system for youth mountain bike racing in the United States, and to report preliminary first-year results. DESIGN Descriptive sports injury epidemiology study. METHODS After two and a half years of development and extensive beta-testing, an electronic injury surveillance system went live in January, 2018. An automated email is sent to a Designated Reporter on each team, with links to the injury reporting form. Data collected include demographic information, injured body part, injury diagnosis, trail conditions and other factors associated with injury occurrence. RESULTS 837 unique injuries were reported in 554 injury events among 18,576 student-athletes. The overall injury event proportion was 3.0%. The most common injury among student-athletes was concussion/possible concussion (22.2%), followed by injuries to the wrist and hand (19.0%). Among 8,738 coaches, there were 134 unique injuries reported that occurred in 68 injury events, resulting in an overall injury event proportion of 0.8%. The shoulder (38.2%) was the most commonly injured body part among coaches. Injuries among coaches tended to more frequently result in fractures, dislocations and hospital admission compared with injuries among student-athletes. Among student-athletes, female riders sustained lower limb injuries more than male riders (34.0% vs. 20.7%, p<0.001). CONCLUSIONS A nationwide injury surveillance system for youth mountain bike racing was successfully implemented in the United States. Overall injury event proportions were relatively low, but many injury events resulted in concussions/possible concussions, fractures, dislocations and 4 weeks or longer of time loss from riding.

Mortality in Different Mountain Sports Activities Primarily Practiced in the Summer Season-A Narrative Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16203920.

Abstract
Millions of people engage in mountain sports activities worldwide. Although leisure-time physical activity is associated with significant health benefits, mountain sports activities also bear an inherent risk for injury and death. However, death risk may vary across various types of mountain sports activities. Epidemiological data represent an important basis for the development of preventive measures. Therefore, the aim of this review is to compare mortality rates and potential risk factors across different (summer) mountain sports activities. A comprehensive literature search was performed on the death risk (mortality) in mountain sports, primarily practiced during the summer season, i.e., mountain hiking, mountain biking, paragliding, trekking, rock, ice and high-altitude climbing. It was found that the death risk varies considerably between different summer mountain sports. Mortality during hiking, trekking and biking in the mountains was lower compared to that during paragliding, or during rock, ice or high-altitude climbing. Traumatic deaths were more common in activities primarily performed by young adults, whereas the number of deaths resulting from cardiovascular diseases was higher in activities preferred by the elderly such as hiking and trekking. Preventive efforts must consider the diversity of mountain sports activities including differences in risk factors and practitioners and may more particularly focus on high-risk activities and high-risk individuals.

Abstract
Objective: Cycling is associated with numerous health benefits but also the risk of traumatic injury. Recent data demonstrate an increase in overall cycling injuries as well as hospital admissions from 1997 to 2013 in the United States. We seek to better understand the causes of the increase in cycling injuries and hospital admissions. Methods: Data regarding cycling-related injuries and hospital admissions were obtained from the National Electronic Injury Surveillance System (NEISS). Participation data were derived from the National Sporting Goods Association Sports Participation Survey, and fatality data were collected from the Fatality Analysis Reporting System (FARS). Population estimates were obtained using a complex survey design. Linear regression was used to evaluate univariate relationships between cycling injuries, hospital admissions, deaths, and participation. To evaluate factors associated with hospital admission, we developed a multivariable logistic regression model that included year, age, gender, body part injured, and injury type (i.e., contusion, fracture, or laceration). Results: The number of individuals who cycle did not change significantly over time, but there was a substantial increase in cycling-related injuries, leading to an increase in per participant injuries from 701/100,000 in 1997 to 1,164/100,000 in 2013. When the injuries were evaluated by age group, younger cyclists have an increased risk for injury, whereas the rise in injuries among older cyclists stemmed from an increase in ridership rather than a unique susceptibility to injury. Trends in hospital admissions and fatalities appeared to be driven by increases in the older age groups. In the multivariable model evaluating factors related to hospital admission, the odds of hospital admission increased for each decade after age 25, as well as male gender and body part injured. Conclusion: On a per participant basis, the rate of cycling-related injuries and hospital admissions increased between 1997 and 2013. This trend likely reflects a combination of shifting demographics among cyclists with an increase in older cyclists who are at increased risk of severe injury.

Abstract
With the increasing popularity of mountain biking, also known as off-road cycling, and the riders pushing the sport into extremes, there has been a corresponding increase in injury. Almost two thirds of acute injuries involve the upper extremities, and a similar proportion of overuse injuries affect the lower extremities. Mountain biking appears to be a high-risk sport for severe spine injuries. New trends of injury patterns are observed with popularity of mountain bike trail parks and freeride cycling. Using protective gear, improving technical proficiency, and physical fitness may somewhat decrease the risk of injuries. Simple modifications in bicycle-rider interface areas and with the bicycle (bike fit) also may decrease some overuse injuries. Bike fit provides the clinician with postural correction during the sport. In this review, we also discuss the importance of race-day management strategies and monitoring the injury trends.

Abstract
BACKGROUND Traffic accidents are the most frequent cause of genitourinary injuries (GUI). Kidney injuries after trauma have been well described. However, there exists a paucity of data on other traumatic GUI after traffic accidents. The objective of this study was to analyze the frequency and type of all GUI, by user category, after traffic accidents. METHODS Patient cases were extracted from the trauma registry of the French department of Rhone from 1996 to 2013. We assessed the urogenital injuries presented by each of road user's categories. Severity injuries were coded with the Abbreviated Injury Scale and the Injury Severity Score. Kidney trauma was mapped with the classification of the American Association for the Surgery of Trauma. Multivariate prediction models were used for analysis of data. RESULTS Of 162,690 victims, 963 presented with GUI (0.59%). 47% were motorcyclists, 22% were in a car, 18% on bicycles, and 9% were pedestrians. The most common organ injury was kidney (41%) followed by testicular (23%). Among the 208 motorists with a GUI, kidney (70%), bladder (10%), and adrenal gland (9%) were the most frequent lesions. Among the 453 motorcyclist victims with GUI, kidney (35%) and testicular (38%) traumas were the most frequent and 62% of injuries involved external genitalia. There were 175 cyclists with GUI, 70% of injuries involved external genitalia; penile traumas (23%) were the most frequent. In total, there were 395 kidney injuries, most being low grade. According to the American Association for the Surgery of Trauma kidney injuries were grade I, 59%; grade II, 11%; grade III, 16%; grade IV, 9%; grade V, 3%; and indeterminate, 2%. CONCLUSION GUI is an infrequent trauma after traffic accidents, with kidneys being the most commonly injured. Physicians must maintain a high awareness for external genitalia injuries in motorcyclists and cyclists. LEVEL OF EVIDENCE Prognostic and epidemiologic study, level III.

Abstract
We evaluated 4 men who had benign paroxysmal positional vertigo (BPPV) that occured several hours after intensive mountain biking but without head trauma. The positional maneuvers in the planes of the posterior and horizontal canals elicited BPPV, as well as transitory nystagmus. This was attributed to both the posterior and horizontal semicircular canals (SCCs) on the left side in 1 patient, in these 2 SCCs on the right side in another patient, and to the right posterior SCC in the other 2 patients. The symptoms disappeared after physiotherapeutic maneuvers in 2 patients and spontaneously in the other 2 patients. Cross-country or downhill mountain biking generates frequent vibratory impacts, which are only partially filtered through the suspension fork and the upper parts of the body. Biomechanically, during a moderate jump, before landing, the head is subjected to an acceleration close to negative 1 g, and during impact it is subjected to an upward acceleration of more than 2 g. Repeated acceleration-deceleration events during intensive off-road biking might generate displacement and/or dislocation of otoconia from the otolithic organs, inducing the typical symptoms of BPPV. This new cause of posttraumatic BPPV should be considered as an injury of minor severity attributed to the practice of mountain biking.

UNLABELLED Brustia, Raffaele, Giulia Enrione, Bruna Catuzzo, Luca Cavoretto, Massimo Pesenti Compagnoni, Enrico Visetti, Emmanuel Cauchy, Stefanie Ziegler, and Guido Giardini. Results of a prospective observational study on mountaineering emergencies in Western Alps: mind your head. High Alt Med Biol. 17:116-121, 2016.- BACKGROUND In the northern Italian district Valle d'Aosta district during winter and summer season the population can increase up to 170% of the resident population. A prospective monocentric observational registry was held to obtain a precise picture of seasonal mountain-related medical and traumatic major events. METHODS From 1st January 2012 to 31st December 2013 all patients admitted to the Aosta Regional Hospital Emergency Room for any event occurred above 2500 m were screened: all those affected by High Altitude Illness, Acute Illness in High Altitude, Trauma, or Cold disease were prospectively included. Activity incidence rate is expressed as the occurrence of mountain-related events per 1000 hours of mountain activity. Event Incidence rate is expressed as the occurrence of new cases per 1000 hours of mountain activity. RESULTS Two hundred two patients were included during the study period. Trauma (65.1% vs. 24.6%, p < 0.001) and head commotive injury (48.1% vs. 15.1%, p < 0.001) were more frequent during winter compared to the summer season. High altitude illness (36.9% vs. 9.3%, p < 0.001) and cold pathologies (15.1% vs. 0.1%, p < 0.001) occurred more frequently in summer than in winter. Patients (51.4%) were immediately discharged from emergency room, 8.4% after a 24-hour observation period, and 30.6% required hospitalization. During summer, the event risk is 0.013 per person and 1000 hours of mountain activity, while in winter, event risk amounts to 0.005 per person and 1000 hours of mountain activity. COMMENTS High altitude medical events or trauma represent <1% of pathologies observed in the emergency room department of a mountain district in the western Alps. Head commotive injury is the most observed mountain-related event in high altitude, in winter and during ski practice. High altitude illness and cold injuries are observed more frequently in summer, during trekking or climbing activities.

BACKGROUND Mountain and road bike accidents are particularly common with the increased popularity of the sport. We reviewed the attendances in our emergency department over a 4-year period looking at cycling injuries to detect the level and grade of these injuries and their outcomes. METHOD Royal Blackburn Hospital caters for a population of 550 000. A search through the Hospital information system revealed 104 patients with fractures following mountain bike injuries. These were looked at in more detail. We present a series of 5 severe shoulder girdle injuries following mountain bike accidents in this cohort, to highlight the serious level of injury sustained in this sport. We searched MEDLINE and EMBASE databases over the past 10 years using the keywords, mountain, biking and fracture. This yielded 7 papers. We compared our series with the literature. RESULTS 104 fractures following mountain bike accidents between 2008 and 2011. Fractures of the upper limb were the most common (88.5%) with the clavicle being the most commonly fractured bone (28.8%). CONCLUSIONS Major scapular injuries with destruction or disruption of the four bar linkage of the shoulder girdle are very common following mountain accidents. Clavicular fractures are the commonest upper limb injury. It is easy to miss a disruption to the four-bar linkage associated with a clavicular injury. This paper highlights the severity of the injuries sustained in mountain bike accidents of the upper limb and requirement of adequate protection in this exhilarating sport.

Abstract
OBJECTIVES The purpose of this study was to calculate exposure-based bicycling hospitalisation rates in Canadian jurisdictions with different helmet legislation and bicycling mode shares, and to examine whether the rates were related to these differences. METHODS Administrative data on hospital stays for bicycling injuries to 10 body region groups and national survey data on bicycling trips were used to calculate hospitalisation rates. Rates were calculated for 44 sex, age and jurisdiction strata for all injury causes and 22 age and jurisdiction strata for traffic-related injury causes. Inferential analyses examined associations between hospitalisation rates and sex, age group, helmet legislation and bicycling mode share. RESULTS In Canada, over the study period 2006-2011, there was an average of 3690 hospitalisations per year and an estimated 593 million annual trips by bicycle among people 12 years of age and older, for a cycling hospitalisation rate of 622 per 100 million trips (95% CI 611 to 633). Hospitalisation rates varied substantially across the jurisdiction, age and sex strata, but only two characteristics explained this variability. For all injury causes, sex was associated with hospitalisation rates; females had rates consistently lower than males. For traffic-related injury causes, higher cycling mode share was consistently associated with lower hospitalisation rates. Helmet legislation was not associated with hospitalisation rates for brain, head, scalp, skull, face or neck injuries. CONCLUSIONS These results suggest that transportation and health policymakers who aim to reduce bicycling injury rates in the population should focus on factors related to increased cycling mode share and female cycling choices. Bicycling routes designed to be physically separated from traffic or along quiet streets fit both these criteria and are associated with lower relative risks of injury.

[PMID: 25530389 DOI: 10.1016/j.urology.2014.07.075] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2014] [Revised: 07/05/2014] [Accepted: 07/09/2014] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To describe epidemiologic features of sports-related genitourinary (GU) injuries and determine patient cohorts and particular sporting activities associated with increased GU injury risk. MATERIALS AND METHODS The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury-related US emergency department (ED) presentations, was analyzed to characterize GU injuries between 2002 and 2010. A total of 13,851 observations were analyzed to derive national estimates. RESULTS Between 2002 and 2010, an estimated 137,525 individuals (95% confidence interval, 104,490-170,620) presented to US EDs with GU injuries sustained during sporting activities. Nearly three-quarters of injuries occurred in the pediatric population. The most common product involved was a bicycle, representing approximately one-third of injuries in both adult and pediatric populations. Injuries related to team sports such as football, baseball or softball, basketball, and soccer were also common, particularly among boys where they represented a combined third of all injuries. Eighty-nine percent of all patients were evaluated and treated in the ED without inpatient admission. The large majority of injuries involved the external genitalia (60%), and significant injuries of paired GU organs (kidneys and testicles) requiring inpatient admission were rare (8.5%). CONCLUSION Sports-related GU injuries are most commonly sustained during the use of a bicycle. However, there are other associated activities with identifiable high-risk cohorts, products, and situations. Consumers, practitioners, and injury-prevention experts can use our epidemiologic data to prioritize and develop strategies aimed at the prevention and limitation of such injuries, particularly when counseling at-risk cohorts, such as those with solitary kidneys or testicles.

Abstract
BACKGROUND Cycling is gaining more popularity both as a sport, on and off-road and also as a means of commute. Cycling accidents harbour significant injury risks including fractures. Proximal femoral fractures are uncommonly associated with cycling in the young adult population. The purpose of this study is to describe this unique pattern of injury as well as the outcome of proximal femoral fractures caused by cycling in the young to mid age population. STUDY DESIGN retrospective cohort study. 23 fractures in 22 patients were available for analysis. 11 were femoral neck fractures, with six displaced ones, and the rest trochanteric fractures. 21 patients were male patients, and the average age was 42 (range 27-60). All patients but two were operated within 24 h from admission. Radiographic analysis included reduction quality, fracture classification and arthritic changes. Clinical outcome was measured using SF-12 and Oxford hip scores. RESULTS All fractures healed. Two patients with displaced femoral neck fractures developed avascular necrosis requiring arthroplasty. One patient developed an AVN 2 years after a stable trochanteric fracture but did not require an arthroplasty as of yet. Eight patients required hardware removal due to symptoms. 77% of patients had resumed cycling at the pre-injury level. Mean SF-12 score was 47.1 ± 11.7 for the physical component and 53.7 ± 6.3 for the mental component. Mean oxford hip score as was 40.1 ± 12.2. Radiographic analysis revealed good to acceptable reduction quality. Fracture type, age, cycling type and reduction were not significantly associated with outcome. CONCLUSION Proximal femoral fractures caused by cycling in young to mid-aged adults are an emerging pattern of injury. Overall favourable result can be expected in the majority of cases, with displaced femoral neck fractures having a risk for AVN. Further delineation of the exact cause for this phenomenon is required with possible intervention for injury prevention.

Abstract
Although generally a safe activity with considerable health benefit, the wide social prevalence of cycling, its performance by both young and elderly riders, and the increasing operation of bicycles in complex urban environments results in a significant incidence of trauma. Orthopedic injuries, followed by head and facial trauma, are most frequent but all anatomic regions can be affected and the spectrum of injury ranges from minor to severe and potentially fatal. Clinicians need to be aware of the range of injuries and causative mechanisms as many patients may present with relatively minor signs and symptoms despite significant underlying pathology. Non-commuter, recreational cyclists are also at risk for injury due to: variable terrain and environmental conditions; increased competitive and risk-taking behavior; technical equipment failure; and poor compliance with protective equipment. Numerous injury preventative strategies have been advocated including: increased rider training; creation of dedicated traffic lanes for commuting cyclists; bike-awareness education for motorists and interventions to improve cyclist visibility; increased utilization of protective equipment and programs to reduce concomitant drug or alcohol use. Of all preventative strategies, bicycle helmets have received the most study, leading to legislated use in some jurisdictions. As urban environments become more congested for commuter cyclists, and interest in recreational and competitive cycling grows, bicycle injury is likely to become more prevalent.

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

Abstract
OBJECTIVE The objective of this study was to examine the patterns of severe injury documented at a northern British Columbia regional trauma center based on age, sex, month of year, activity type, injury type, and injury severity as they relate to participation in outdoor recreational activities. METHODS A retrospective analysis of data abstracted from the British Columbia Trauma Registry for patients sustaining injuries between April 1, 2004, and March 31, 2007, while engaged in outdoor recreational activities in the Northern Health Authority. The British Columbia Trauma Registry inclusion criteria are as follows: 1) admitted for treatment of injuries sustained from the transfer of external energy or force; 2) admitted to the facility within 7 days of injury; and 3) length of stay more than 2 days or in-hospital mortality. RESULTS In all, 159 patients met study criteria. August and September were peak injury months (mean 7.3 and 7.0 per month, respectively). The highest injury patterns involved cycling (n = 31), all-terrain vehicle operation (n = 30), horseback riding (n = 22), and snowmobiling (n = 22). Of the 159 patients, 76.1% were male, with a peak age distribution between 10 years and 19 years (22%). Males were more commonly injured than females among cycling (83.9%), all-terrain vehicle (86.7%), and snowmobile (100%) traumas. Females were more commonly injured from horseback riding events (42.1%). CONCLUSIONS This study emphasizes the need for rapid translation of research findings into injury prevention awareness and programming in northern British Columbia, particularly relating to cycling, horseback riding, snowmobiling, and all-terrain vehicle operation. Further investigation is required to analyze long-term outcomes for this common injury population.

Abstract
BACKGROUND Street and mountain bicycling are popular recreational activities and prevalent modes of transportation with the potential for severe injury. The purpose of this investigation was to compare the incidence, risk factors and injury patterns among adults with severe street versus mountain bicycling injuries. METHODS We conducted a retrospective cohort study using the Southern Alberta Trauma Database of all adults who were severely injured (injury severity score [ISS] ≥ 12) while street or mountain bicycling between Apr. 1, 1995, and Mar. 31, 2009. RESULTS Among 11 772 severely injured patients, 258 (2.2%) were injured (mean ISS 17, hospital stay 6 d, mortality 7%) while street (n = 209) or mountain bicycling (n = 49). Street cyclists were often injured after being struck by a motor vehicle, whereas mountain bikers were frequently injured after faulty jump attempts, bike tricks and falls (cliffs, roadsides, embankments). Mountain cyclists were admitted more often on weekends than weekdays (61.2% v. 45.0%, p = 0.040). Injury patterns were similar for both cohorts (all p > 0.05), with trauma to the head (67.4%), extremities (38.4%), chest (34.1%), face (26.0%) and abdomen (10.1%) being common. Spinal injuries, however, were more frequent among mountain cyclists (65.3% v. 41.1%, p = 0.003). Surgical intervention was required in 33.3% of patients (9.7% open reduction internal fixation, 7.8% spinal fixation, 7.0% craniotomy, 5.8% facial repair and 2.7% laparotomy). CONCLUSION With the exception of spine injuries, severely injured cyclists display similar patterns of injury and comparable outcomes, regardless of style (street v. mountain). Helmets and thoracic protection should be advocated for injury prevention.

Abstract
This case-control study describes the profile of bicyclists injured in mountain bike terrain parks (MBTPs) and examines risk factors for severe injury among MBTP riders. Cases were hospitalised bicyclists injured in MBTPs. Controls were bicyclists injured in MBTPs who were discharged from the emergency department. No significant differences were observed in the distribution of age and sex between cases and controls. A higher proportion of cases compared with controls suffered a head injury (22%), fracture (41%) or internal organ injury (32%). Controls suffered a higher proportion of superficial injuries (26%), sprains (10%) or wounds (16%). Upper extremity protective equipment (e.g. elbow or shoulder pads) was used more by cases than controls (23% vs. 11%, p = 0.03). Riders who self-reported cycling faster than usual had significantly higher risk of severe injury compared with others. The risk of severe injury may be reduced by encouraging bicyclists to control their speed or by modifying MBTP design to limit the opportunity to gain speed.

Abstract
BACKGROUND The purpose of this study was to describe patterns and rates of sport and active recreation injuries that result in major trauma or death and to examine trends in these rates for all sport and active recreation activities and key sporting groups, for the period July 2001-June 2007, in Victoria, Australia. METHODS All sport and active recreation related major trauma cases and deaths were extracted from the Victorian State Trauma Registry (VSTR) and the National Coroners Information System, for the period July 2001-June 2007. Participation data from the Exercise Recreation and Sports Survey (ERASS) was used to establish incidence rates for the group as a whole and for key sporting groups. Poisson regression analysis was used to examine trends in major trauma and death due to participation in sport and active recreation across the six year study period. RESULTS There were 1019 non-fatal major trauma cases and 218 deaths. The rate of major trauma or death from sport and active recreation injuries was 6.3 per 100,000 participants per year. There was an average annual increase of 10% per year in the major trauma rate (including deaths) across the study period, for the group as a whole (IRR 1.10, 95% CI, 1.06-1.14). There was no increase in the death rate (IRR=0.94, 95% CI, 0.87-1.02; p=0.12). Significant increases were also found for cycling (IRR 1.16, 95% CI, 1.09-1.24) off-road motor sports (IRR 1.10, 95% CI, 1.03-1.19), Australian football (IRR 1.21, 95% CI, 1.03-1.42) and swimming (IRR 1.16, 95% CI, 1.004-1.33). CONCLUSION The rate of major trauma inclusive of deaths, due to participation in sport and active recreation has increased over recent years, in Victoria, Australia. Much of this increase can be attributed to cycling, off-road motor sports, Australian football and to a lesser extent swimming, highlighting the need for co-ordinated injury prevention in these areas.

Abstract
OBJECTIVE The popularity of mountain bicycle (MTB) riding has increased significantly since its inception in the 1970s, as have injuries from MTB riding. As MTB stage racing is a relatively new segment of MTB racing, the purpose of this study was to evaluate the injury and illness patterns associated with MTB stage racing to assist future medical providers in covering events. METHODS The Trans-Sylvania Mountain Bike Epic Race consisted of 7 stages. An onsite medical team of physicians, nurses, and paramedics provided medical coverage. The providers logged each medical encounter on a medical form. The log included the location where the treatment was provided (on course, at the finish or after the race), a description of the injury/illness, treatment that was rendered, the supplies needed for treatment, and the disposition of the patient (continue, withdraw but continue the next day, withdraw, or transfer to the hospital). RESULTS A total of 52 athletes competed in the inaugural edition of the race. There were 30 separate medical encounters, with a total of 34 injuries/illnesses. Of these, 22 (65%) were classified as injury, and 12 (35%) were classified as illness. Four athletes withdrew from the race, 1 from injury and 3 from illness. Skin and soft tissue injuries/illnesses were the most prevalent. CONCLUSIONS Injury and illness patterns of MTB stage racing are similar to those of other wilderness sporting events and prior data on MTB-related injuries. Minor skin, soft tissue, and orthopedic injuries are the most common. Illness accounts for the majority of withdrawals.

Abstract
BACKGROUND The increasing popularity of climbing activities is associated with a rise in the number of respective injuries and overuse syndromes. However, a comprehensive scrutiny of the incidence, kind and severity of climbing-related ailments in Austria is so far outstanding. We aimed to evaluate injuries and overuse syndromes in sport climbing and bouldering in Austria and to investigate whether the injury incidence differs between specific groups of climbers. DESIGN Retrospective cross-sectional self-report study. METHODS A self-report questionnaire to assess (a) demographic and anthropometric characteristics, (b) climbing experience and skill level, and (c) detailed information on climbing-related injuries was made available in climbing halls and on the Internet. Data from 193 climbers (133 males and 60 females; age 30.4 ± 8.1 years; average climbing experience 9.3 ± 7.7 years) were acquired. RESULTS A total of 374 injuries were reported by 130 participants (67.4 %). The single most common differential diagnoses, accounting for 56.7 % of all injuries, were strains and ruptures of annular ligaments of the fingers, lateral epicondylitis of the elbow, and sprains or fractures of the ankle joint. The odds for strains of the annular ligaments and lateral epicondylitis were greater in men and increased with older age and higher exposure to climbing stress. CONCLUSIONS This is the first comprehensive study investigating climbing-related injuries in Austria. The incidence and kind of the ailments reported confirm results of previous studies. Moreover, our results suggest that the risk to suffer climbing-related overuse syndromes, but not acute injuries, is dependent on sex, age, and exposure to climbing stress.

Abstract
OBJECTIVE To report the demographic characteristics, injury rate, severity, and morbidity in BASE jumping. DESIGN Cross-sectional survey. SETTING BASE jumping group meetings from 2006 to 2010. PARTICIPANTS Heterogenic group of 102 International BASE jumpers. ASSESSMENT OF RISK FACTORS Injuries reported as function of jumps made, jumping days, age, experience, and sex. MAIN OUTCOME MEASURES Incidence, severity, and type of injuries. RESULTS Responses from 68 subjects were available for analysis. The median number of jumps was estimated at 286 per respondent. The median time respondents had participated in BASE jumping was 5.8 years. There were 39 reported severe injuries sustained by 29 different jumpers. Nineteen thousand four hundred ninety-seven jumps were reported, resulting in 2 severe injuries per 1000 jumps (0.2% severe injury rate) or 2.6 severe injuries per 1000 jumping days. Forty-nine respondents (72%) had witnessed the death or serious injury of other participants in the sport. Twenty-four accidents (61%) involved the lower limbs, 8 (20%) the back/spine, 7 (18%) the chest wall, and 5 (13%) were a head injury. The mean Abbreviated Injury Score was 3.2 (range, 2-5). Fifteen (52%) of the 29 injured jumpers required 20 acute surgical interventions, which were mostly orthopedic related. There was a significant correlation between number of jumps made and injuries sustained (P < 0.05). CONCLUSIONS BASE jumpers have an average of 1 severe injury for every 500 jumps. Most active BASE jumpers have witnessed death or severe injury of a participant and have experienced a "close call" incident.

Abstract
OBJECTIVE The objective of this review is to summarize evidence on injuries occurring in individuals participating in mountain and wilderness sports. DATA SOURCES Scopus, ISI Web of Knowledge, SPORTDiscus, Ovid Safety and Health, Index to Theses, COPAC, and sportscotland e-library. The search terms were (mountain* or wilderness or adventure or climb* or (hill walk*)) and (accident* or injur* or rescue*) and (epidemiolog* or statistic* or pattern* or survey*). The search period was from 1987 to 2010. STUDY SELECTION A total of 2034 articles were identified. The full text of 137 articles was retrieved. Fifty articles met inclusion criteria-mountain and wilderness; nonmotorized, leisure time, outdoor activities; and nonfatal injury. Skiing and snowboarding articles were excluded. DATA EXTRACTION Study design was classified using the "STOX" hierarchy of evidence. Study quality was rated independently by 2 reviewers. DATA SYNTHESIS All studies were observational. Twenty-one (42%) were longitudinal, 20 (40%) were cross-sectional surveys, and 9 were cohort studies. A majority of casualties were aged 20 to 39 years. There was a clear male majority, 70% to 89% in most studies. The percentage of casualties who sustained severe injuries ranged from 5% to 10%--less than 10% were admitted to hospital. Casualties sustained an average of 1.2 to 2.8 injuries (most >1.6), which mainly affected the soft tissues; between 2% and 38% were fractures. Up to 90% of injuries were to the extremities. CONCLUSIONS The majority of mountain and wilderness sports injuries are minor to moderate. However, some casualties have life-threatening medical problems, which may have long-term implications for return to sport and general well-being.

Abstract
OBJECTIVE To use the National Trauma Data Bank (NTDB) to evaluate bicycling-related genitourinary (GU) injury. Bicycling is a popular recreational and competitive sport with recognized risks. GU injuries associated with bicycling is unknown. METHODS Patient cases were extracted from the NTDB, version 9.1, using the mechanism of injury Ecode for pedal cyclist and ICD-9 codes for GU injuries. The type of GU injuries, patient demographics, Injury Severity Score, surgical management, outcomes, and disposition were analyzed. RESULTS Of 635,013 trauma cases evaluated, 16,585 were identified as trauma because of bicycle injury. GU injuries were sustained in 358 (2%) patients; 86% were male, with a mean age of 29 years. The most commonly injured GU organ was the kidney (75%), followed by bladder and urethra (15%), and penis and scrotum (10%). These injuries resulted in nephrectomy (0.4%), cystorrhaphy (11.3%), scrotorrhaphy (42.1%), testicular repair (3.1%), and penile repair (7.5%). Most common associated injuries included vertebral fracture (35%), pelvic fracture (25%), spleen (19%), and open head wound (15%). Patients who sustained a vertebral fracture commonly sustained a concomitant bladder and urethra (37.7%) or a renal injury (22.6%). CONCLUSION GU injury is an infrequent occurrence with bicycle trauma, occurring in 2% of bicycle injuries, with kidneys being the most commonly injured GU organ. Physicians treating bicyclists who sustained a vertebral fracture should be aware of a possible concomitant renal or bladder injury. Young males appear to be principally at risk for GU injury.

Abstract
Despite public health measures to prevent childhood injuries, the incidence of pediatric fractures is increasing. This fracture incidence is dependent on many demographic factors, the various contributors to bone health, and an individual's risk-taking behavior. Although traditional play activities continue to be the prevalent causes for fractures, there is an evolving array of new sport and recreation activities that carry significant fracture risk. The following review article outlines the developing epidemiology of pediatric fractures by analyzing some of the individual risk factors that influence fracture incidence as well as the variety of activities that are associated with these fractures.

Abstract
BACKGROUND Multiple studies have described in general the injuries associated with mountain biking, and detailed accounts of spine injuries sustained in hockey, gymnastics, skiing, snowboarding, rugby, and paragliding have previously been published. However, no large-scale detailed assessment of mountain biking associated spinal fractures and spinal cord injuries has previously been published. PURPOSE This study was undertaken to describe the patient demographics, injuries, mechanisms, treatments, outcomes, and resource requirements associated with spine injuries sustained while mountain biking. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients who were injured while mountain biking, and who were seen at a provincial spine referral center between 1995 and 2007 inclusive, with spinal cord injuries and/or spine fracture were included. A chart review was performed to obtain demographic data, and details of the injury, treatment, outcome, and resource requirements. RESULTS A total of 102 men and 5 women were identified for inclusion. The mean age at injury was 32.7 years (95% confidence interval 30.6, 35.0). Seventy-nine patients (73.8%) sustained cervical injuries, while the remainder sustained thoracic or lumbar injuries. Forty-three patients (40.2%) sustained a spinal cord injury. Of those with cord injuries, 18 (41.9%) were American Spinal Injury Association (ASIA) A, 5 (11.6%) were ASIA B, 10 (23.3%) ASIA C, and 10 (23.3%) ASIA D. Sixty-seven patients (62.6%) required surgical treatment. The mean length of stay in an acute hospital bed was 16.9 days (95% confidence interval 13.1, 30.0). Thirty-three patients (30.8%) required intensive care unit attention, and 31 patients (29.0%) required inpatient rehabilitation. Of the 43 patients (40.2%) seen with spinal cord injuries, 14 (32.5%) improved by 1 ASIA category, and 1 (2.3%) improved by 2 ASIA categories. Two patients remained ventilator-dependent at discharge. CONCLUSION Spine fractures and spinal cord injuries caused by mountain biking accidents typically affect young, male, recreational riders. The medical, personal, and societal costs of these injuries are high. Injury prevention should remain a primary goal, and further research is necessary to explore the utility of educational programs, and the effect of helmets and other protective gear on spine injuries sustained while mountain biking.

Abstract
For more than two decades the popularity of mountain biking as a national pastime as well as a competitive sport has been undiminished. However, its related risks are not monitored as closely as those, for example, of skiing. The injuries caused by mountain biking are specific and cannot be compared with those caused by other cycling sports. This is due not only to the characteristics of the terrain but also to the readiness to assume a higher risk compared to cycle racing.The particular value of radiology is in the acute trauma setting. Most often musculoskeletal lesions must be examined and digital radiography and MRI are the most useful techniques. Severe trauma of the cranium, face, spine, thorax and abdomen are primarily evaluated with CT, particularly in dedicated trauma centers. Therefore, radiology can play a role in the rapid diagnosis and optimal treatment of the trauma-related injuries of mountain biking. Thus, the unnecessarily high economical damage associated with mountain biking can be avoided.

Abstract
Cycling is often considered a leisurely activity with minimal potential for severe or chronic injury. Acute head and spinal trauma can be devastating and can predominantly contribute to all-cause mortality in injuries attributed to cycling. Chronic overuse injuries primarily affecting the ulnar, median, and pudendal nerves are also a cause of significant morbidity for the cyclist.
