A retrospective analysis of mission reports in the national Swedish Police Registry on mountain rescue 2018-2022: here be snowmobiles.

BACKGROUND: Increasing mountain activity and decreasing participant preparedness, as well as climate change, suggest needs to tailor mountain rescue. In Sweden, previous medical research of these services are lacking. The aim of the study is to describe Swedish mountain rescue missions as a basis for future studies, public education, resource allocation, and rescuer training. METHODS: Retrospective analysis of all mission reports in the national Swedish Police Registry on Mountain Rescue 2018-2022 (n = 1543). Outcome measures were frequencies and characteristics of missions, casualties, fatalities, traumatic injuries, medical conditions, and incident mechanisms. RESULTS: Jämtland county had the highest proportion of missions (38%), followed by Norrbotten county (36%). 2% of missions involved ≥ 4 casualties, and 44% involved ≥ 4 mountain rescuers. Helicopter use was recorded in 59% of missions. Non-Swedish citizens were rescued in 12% of missions. 37% of casualties were females. 14% of casualties were ≥ 66 or ≤ 12 years of age. Of a total 39 fatalities, cardiac event (n = 14) was the most frequent cause of death, followed by trauma (n = 10) and drowning (n = 8). There was one avalanche fatality. 8 fatalities were related to snowmobiling, and of the total 1543 missions, 309 (20%) were addressing snowmobiling incidents. Of non-fatal casualties, 431 involved a medical condition, of which 90 (21%) suffered hypothermia and 73 (17%) cardiovascular illness. CONCLUSIONS: These baseline data suggest snowmobiling, cardiac events, drownings, multi-casualty incidents, and backcountry internal medicine merit future study and intervention.

Suspension syndrome: a scoping review and recommendations from the International Commission for Mountain Emergency Medicine (ICAR MEDCOM).

BACKGROUND: Suspension syndrome describes a multifactorial cardio-circulatory collapse during passive hanging on a rope or in a harness system in a vertical or near-vertical position. The pathophysiology is still debated controversially. AIMS: The International Commission for Mountain Emergency Medicine (ICAR MedCom) performed a scoping review to identify all articles with original epidemiological and medical data to understand the pathophysiology of suspension syndrome and develop updated recommendations for the definition, prevention, and management of suspension syndrome. METHODS: A literature search was performed in PubMed, Embase, Web of Science and the Cochrane library. The bibliographies of the eligible articles for this review were additionally screened. RESULTS: The online literature search yielded 210 articles, scanning of the references yielded another 30 articles. Finally, 23 articles were included into this work. CONCLUSIONS: Suspension Syndrome is a rare entity. A neurocardiogenic reflex may lead to bradycardia, arterial hypotension, loss of consciousness and cardiac arrest. Concomitant causes, such as pain from being suspended, traumatic injuries and accidental hypothermia may contribute to the development of the Suspension Syndrome. Preventive factors include using a well-fitting sit harness, which does not cause discomfort while being suspended, and activating the muscle pump of the legs. Expediting help to extricate the suspended person is key. In a peri-arrest situation, the person should be positioned supine and standard advanced life support should be initiated immediately. Reversible causes of cardiac arrest caused or aggravated by suspension syndrome, e.g., hyperkalaemia, pulmonary embolism, hypoxia, and hypothermia, should be considered. In the hospital, blood and further exams should assess organ injuries caused by suspension syndrome.

Women's Health at High Altitude: An Introduction to a 7-Part Series by the International Climbing and Mountaineering Federation Medical Commission.

Horakova, Lenka, Peter Paal, Jacqueline Pichler Hefti, Marija Andjelkovic, Beth A. Beidleman, Mia Derstine, David Hillebrandt, Dominique Jean, Kaste Mateikaite-Pipiriene, Alison J. Rosier, Susi Kriemler, and Linda E. Keyes. Women's health at high altitude: An introduction to a 7-part series by the International Climbing and Mountaineering Federation Medical Commission. High Alt Med Biol. 24:243-246, 2023. Background: Women have been traveling to high altitude since the inception of modern mountaineering. Although there are distinct female-specific features such as menstruation and menopause relevant to adaptation to and performance at high altitude, very little data exist on women's high-altitude health. To summarize what is known to date, the Medical Commission of the International Climbing and Mountaineering Federation (UIAA) has created a series of articles on women's health, high altitude illness, and performance at high altitude. Methods: Assembling an international author team, two types of manuscripts were developed: (1) reviews on female-specific topics such as pregnancy; (2) reviews on sex differences in high-altitude related illnesses, nutrition, cold injuries, and mortality. Results: The literature search yielded 7,165 articles, with 482 studies meeting the inclusion criteria for full-text review. The authors of individual chapters reviewed these articles and performed additional hand searches. Conclusions: Some important questions on women sojourning and exercising at high altitude have been studied, but many are still awaiting a qualified and evidence-based response. Our seven reviews, to be published in future issues of this journal, summarize what is known about lowland women sojourning at high altitude, provide recommendations, and highlight knowledge gaps in high altitude women's medicine.

Frostbite and Mortality in Mountaineering Women: A Scoping Review-UIAA Medical Commission Recommendations.

Kriemler, Susi, Kaste Mateikaite-Pipiriene, Alison Rosier, Linda E. Keyes, Peter Paal, Marija Andjelkovic, Beth A. Beidleman, Mia Derstine, Jacqueline Pichler Hefti, David Hillebrandt, Lenka Horakova, and Dominique Jean; for the UIAA MedCom Writing Group on Women's Health in the Mountains. Frostbite and mortality in mountaineering women: a scoping review-UIAA Medical Commission recommendations. High Alt Med Biol. 24:247-258, 2023. Background: The harsh environment of high altitudes (HA) poses many serious health risks for mountaineers, including cold injuries and death. The aim of this work was to review whether female mountaineers are at special risk for frostbite or death at HA compared with their male counterparts. Methods: The UIAA Medical Commission convened an international author team to review women's health issues at HA and to publish updated recommendations. Pertinent literature from PubMed and Cochrane was identified with additional publications found by hand search. The primary search focus was for articles assessing cold injuries and death in women mountaineers at HA. Results: We reviewed the literature and identified 20 relevant studies: 2 studies on frostbite at HA, plus 7 studies and 1 report for death at HA. An additional 10 studies about frostbite at low altitude were included. We found that female mountaineers at HA were at lower risk of death than their male counterparts, but sex differences in frostbite were inconclusive. Conclusions: The frequency of cold injuries and mortality in female mountaineers is not yet well studied, and the studies that have been published tend to lack precise exposure data. More studies and registries with sex-differentiated data are needed.

Rehabilitation of Annular Pulley Injuries of the Fingers in Climbers: A Clinical Commentary.

ABSTRACT: The annular pulley ligaments of the fingers are one of the most injured anatomical structures in those who participate in climbing. Despite this, there is a paucity of guidance clearly describing the rehabilitation and physical preparation parameters to return to sport following such injuries. The foundation of effective rehabilitation is the judicious application of progressive loading to increase the morphological and material properties of the damaged tissues. We maintain the optimal management of the climbing athlete after a traumatic annular flexor pulley system rupture should be grounded in the principles of strength and conditioning.

Self-Reported Injuries in Indoor Gym-Based Rock Climbers: A Retrospective Study of Predictors of Prolonged Injury and Seeking Medical Care.

INTRODUCTION: Indoor climbing injuries are often related to overuse, and climbers choose between self-management and seeing a medical practitioner. This study evaluated predictors of prolonged injury and seeking medical care for indoor climbing injuries. METHODS: A convenience sample of adult climbers from 5 gyms in New York City was interviewed about injuries over the past 3 y, because of which they stopped climbing for at least a week or saw a medical practitioner. RESULTS: In total, 122 of 284 (43%) participants had at least 1 injury, for a total of 158 injuries. Fifty (32%) were prolonged, lasting at least 12 wk. Predictors of prolonged injury included older age (odds ratio [OR], 2.28, per 10-y increase; 95% CI, 1.31-3.96), hours per week spent climbing (OR, 1.14, per 1-h increase; 95% CI, 1.06-1.24), climbing difficulty (OR, 2.19, per difficulty group increase; 95% CI, 1.31-3.66), and years of climbing experience (OR, 3.99, per 5-y increase; 95% CI, 1.61-9.84). Only 38% of injuries were seen by a medical practitioner. Predictors of seeking care included prolonged injury (OR, 3.04; 95% CI, 1.39-6.64) and rope climbing preference (OR, 1.98; 95% CI, 1.02-3.82). The most common theme for seeking care was serious pain or interference with climbing or daily activities. CONCLUSIONS: Despite prolonged injuries being common, especially in older, more experienced, and higher-level climbers, only a third of climbers with injuries seek medical care. Outside of injuries causing minimal pain or limitation, those who self-managed reported receiving advice from other climbers or online research as a prominent reason for that choice.

A Guide to Indoor Rock Climbing Injuries.

ABSTRACT: Rock climbing is an increasingly popular indoor sport with a sizable risk of overuse injuries. Yet, many medical practitioners have little familiarity with evaluating and treating climbing injuries because of the terminology, biomechanical demands, mechanisms of injury, and return to sport counseling needed, unique to the sport. This review seeks to educate practitioners on these aspects. Upper extremity injuries occur more frequently than lower extremity injuries, with finger injuries being most prevalent. Pulley injuries, consisting of rupture of the A2 or A4 annular pulleys are the most common type of injury. Other finger injuries include tenosynovitis of the flexor tendons, as well as lumbrical muscle tears. Elbow injuries occur frequently, with medial epicondylopathy being most common. Brachialis injuries are seldom seen outside of climbing. Lower-extremity injuries are typically more acute in nature, including ankle injuries from falls and knee injuries from strenuous climbing moves.

Epidemiology of Emergency Medical Search and Rescue in the North Shore Mountains of Vancouver, Canada, from 1995 to 2020.

INTRODUCTION: Little is known about the epidemiology of emergency medical search and rescue incidents globally. The purpose of this study was to describe the epidemiology of emergency medical search and rescue incidents in the North Shore Mountains of Vancouver, British Columbia, Canada. METHODS: This was a retrospective review and descriptive analysis of search and rescue incident reports created by North Shore Rescue over a 25 y period from 1995 to 2019, inclusive. Incident reports were screened for inclusion against a priori criteria defining a medical callout. The National Advisory Committee of Aeronautics (NACA) severity score was used as a method to grade medical acuity of included subjects. RESULTS: We included 906 subjects. Their median age was 35 y (interquartile range, 24-53), and 65% of subjects were men. Forty-one percent (n=371) of subjects were classified as non-trauma and 54% (n=489) as trauma. The top 3 activities were hiking (53%), biking (10%), and snow sports (10%). Forty-nine percent of incidents were classified as having a NACA score of ≥3. For subjects with trauma, the top 3 body regions were lower limb (52%), head (18%), and torso (12%). For subjects with non-traumatic conditions, the top 3 causes were mental health crises (25%), exposure (25%), and cardiovascular incidents (11%). CONCLUSIONS: Half of the incidents were serious enough to require medical assessment at a hospital (NACA score ≥3). Given this medical acuity, there is a need for evidence-based guidelines and core training competencies for mountain medical search and rescue. Standardized core data sets and outcomes are needed to monitor quality of care over time.

Primary Periphyseal Stress Injuries of the Fingers in Adolescent Climbers: A Critical Review.

ABSTRACT: The worldwide rise in popularity of climbing and development of climbing as a competitive sport is reflected by its debut at the 2021 Summer Olympic Games in Tokyo. Digital primary periphyseal stress injuries in adolescent climbers may pose a significant risk to long-term skeletal health. The aim of this article is to critically review research on the diagnosis and management of primary periphyseal stress injuries of the fingers in adolescent climbers. We adopted a systematic approach to searching for relevant literature. Articles were identified after searches of the following electronic databases: Discover, Academic Search Complete, PubMed, Embase, SPORTDiscus, and ScienceDirect. Conclusive evidence suggests digital primary periphyseal stress injuries are a consequence of repetitive microtrauma. Pain reported by adolescent climbers on the dorsal aspect of the proximal interphalangeal joint should be investigated promptly to avoid serious negative consequences. Clinicians should be aware of the efficacy of imaging techniques to inform a clinical diagnosis. A conservative management approach is preferred but in rare cases surgical intervention may be necessary. A diagnostic and therapeutic algorithm for digital primary periphyseal stress injuries is presented.

Head Injuries in Rock Climbing: A Scoping Review.

Rock climbing was recognized as a sport at the 2020 Tokyo Olympics. Despite its increasing participation, there is no knowledge synthesis of head injuries (HIs), defined as any injury to the head, associated with climbing, making it challenging for clinicians to provide evidence-based care. Our aim was to synthesize HI literature within rock climbing and identify knowledge gaps. Six databases (Medline, Embase, Sports Medicine & Education Index, SPORTDiscus, CINAHL, and Cochrane) were searched. Two reviewers screened 345 studies and 31 studies were selected for data abstraction. We found the quality of individual studies mainly "fair" to "good." Both HI and traumatic brain injury (TBI) had inconsistent definitions and categorization. The HIs represented between 0 to 36% of reported climbing injuries. Between 11 to 100% of HIs were TBIs, defined as an HI with permanent or temporary neurological sequelae. The most common causes of HIs were outdoor falls and falling objects. Climbing-specific factors associated with the causes were infrequently examined in the literature. Data sources of safety practices were incomplete. Overall, there was a lack of literature examining HIs, mechanisms of injury, and safety practices associated with climbing. To improve the tracking of HIs in climbing, we suggest the use of consistent reporting standards and the creation of a climbing injury surveillance system.

[Bouldering: a sport with a high risk of intraarticular fractures]. / Bouldern ­ Trendsport für jedermann mit Potential zu schwerwiegenden Gelenkverletzungen.

Bouldering is a famous new sport with an increasing number of athletes. It became an Olympic sport in 2020. As no major sports equipment is required, everybody can take up bouldering even with little knowledge. However, despite the low climbing height there is a high risk of severe joint injuries, especially in the lower limb. Increasing numbers of climbers have led to an increase in injuries. New floor designs are supposed to reduce these risks. Improved documentation and specific research in bouldering should provide more insight into risks, injury patterns and prevention.

Risk profiles in two different alpine rock climbing styles.

INTRODUCTION: The aim of this study is to evaluate the injury risk profile of the two different styles of rock climbing, alpine climbing with minor route protection (AC) and alpine sport climbing on well-protected routes (SC), in order to develop preventive strategies for risk management.  PATIENTS AND METHODS : 18 SC and 12 AC rock climbing accidents were evaluated retrospectively with a focus on climbers` demographics (age, experience, training intensity, performance level), accident demographics (unforeseen events preceding the injury, ascending or descending, fall height), injury patterns (injury severity, pathologies, pathomechanism) and environmental conditions (rock characteristics, route frequency, route grade, weather).  RESULTS : Injuries were mainly sustained by male lead climbers during ascent (80%). The lower extremity was injured in 46%, the upper extremity in 40%, the pelvis in 6% and the head, chest and spine in 3%. Climbers were significantly older (43 vs. 31 years; p=0.03) and more experienced (21.5 vs. 5.7 climbing years) in AC. Falling height was significantly greater in AC (14.8 vs. 4.7m). Unforeseen events preceding the injury differed significantly between both groups. Slipping off and letting go preceded the fall in 78% in SC, while rock dislodging occurred only in AC. There was a tendency that climbers in SC climbed near or above their performance level, while climbers in AC climbed below their level. SC climbers tended to show more ankle fractures while AC climbers tended to present more cases with multiple injuries. DISCUSSION: AC and SC climbers differ in their risk profiles. Poorer route protection in AC resulted in more severe injuries. Yet in SC routes, good protection alone was not enough to avoid severe injuries. For prevention, climbers should be aware of the specific risks in AC and SC routes and should adjust their behaviour accordingly. Athletic skills were overestimated in SC, while alpine demands were underestimated in AC. A higher focus on visual and haptic grip control may help to prevent loss of hold. A careful lining of the rope into solid rock can reduce rockfalls for the seconder. Continuous attention is mandatory in rope handling and belaying. Applying more mobile pros is recommended in AC because they may shorten fall heights.

Cases of Lightning Strikes during Mountain-Sports Activities: An Analysis of Emergencies from the Swiss Alps.

BACKGROUND: Lightning strikes are a risk during mountain-sport activities. Yet little is known about the prevalence of injuries related to lightning strikes during mountain hiking, backcountry skiing, or high-altitude mountaineering. This study therefore examined the occurrence and characteristics of lightning-strike-related emergencies during mountain-sport activities in the Swiss Alps. METHODS: We analyzed 11,221 alpine emergencies during mountain hiking, 4687 during high-altitude mountaineering, and 3044 during backcountry skiing in the observational period from 2009 to 2020. Identified cases were analyzed in detail regarding age, sex, the time of occurrence, altitude, location, the severity of the injury as quantified by its NACA Score (National Advisory Committee for Aeronautics Score), and injury pattern. RESULTS: We found no cases related to backcountry skiing. Eight cases of lightning strikes during mountain hiking (four female and four male) were identified. The mean age was 32.5 ± 17.5 years, the mean NACA Score was 2.5 ± 1.9, and the mean altitude was 1883.8 ± 425.7 m. None of these cases were fatal, and only one victim was seriously injured. Fifteen cases were identified during high-altitude mountaineering (four female and 11 male). The mean age was 38.7 ± 5.2 years, the mean NACA Score was 3.1 ± 2.5, and the mean altitude was 3486.4 ± 614.3 m. Two lightning strikes were fatal. In these two cases, rope partners were injured by a lightning strike (NACA Score = 4). Most cases were on relatively exposed terrain, such as the Matterhorn Hörnligrat or the Eiger Mittellegigrat. DISCUSSION: The typical victims were 30-40-year-old men. It is possible that the lightning strikes are a consequence of a lower risk aversion among these alpinists, which is be supported by the fact that most of the events occurred on famous mountains such as the Matterhorn or Eiger. Furthermore, since most of the locations were on relatively exposed terrain where one could not quickly find shelter, we recommend careful tour planning with serious consultation of the weather forecast and the likelihood of thunderstorms before climbing exposed sections to prevent emergencies related to lightning strikes.

Epidemiological Study of Foot Injuries in the Practice of Sport Climbing.

BACKGROUND: Climbing is a multidisciplinary sport, where the main objective is to reach the highest point of a rock wall or to reach the end of an established route. There are different types of modalities: sport climbing and traditional climbing. The risks and precautions taken with respect to this sport will directly affect the epidemiology of injuries related to its practice. The present study was designed to identify and characterize the most frequent injuries in the feet of climbers and to determine if there is a relationship between the injuries that appear and the time spent practicing the sport. METHODS: A total of 53 people were collected, 32 men and 21 women, corresponding to the climbers of the FEXME (Extremadura Federation of Mountain and Climbing). To determine the diagnoses, exploratory tests, classified according to the variables to be studied, are carried out: inspection variables and questionnaire variables. RESULTS: The average number of years of climbing was seven years, and the average number of hours of training per week was 6.6 h. Some type of alterations were presented in 70% of the respondents, and foot pain was present during climbing in 45% of the participants. The p-value showed a relationship between years of climbing and the occurrence of chronic foot injuries (p = 0.035), however, there is no relationship between the occurrence of injuries and chronological age. CONCLUSION: We can see that the most frequent injuries in the practice of climbing are claw toes, dermal alterations such as bursitis of the first toe and hallux limitus, followed by hallux valgus. Similarly, only a significant relationship was found between the number of years of climbing and the appearance of foot injuries.

Early Sport Specialization and Past Injury in Competitive Youth Rock Climbers.

INTRODUCTION: Sport specialization has been shown to have negative effects on athletes but has not been studied within rock climbing. This study seeks to evaluate the proportion and impact of specialization in pediatric climbers. METHODS: Climbers (ages 8-18 y) were recruited from throughout the United States to complete a 1-time survey regarding climbing experience, training patterns, and injury history. The main outcome of proportion of climbers suffering an injury was assessed within the last 12 mo and within their entire climbing experience (defined as "lifetime" injury). Early specialization was defined as exclusive participation in climbing, with training for >8 mo‧y-1, prior to age 12 y (late specialization if after age 12 y). RESULTS: Participants (n=111, 14±3 y [mean±SD], 69 females) were high-level climbers. Fifty-five percent of participants specialized in climbing, and 69% of those specialized early. Hand and ankle injuries occurred most commonly. Seventy-eight percent of late specialized climbers had a lifetime injury. Late specialized climbers were 1.6 times (95% CI: 1.1-2.3) more likely than early specialized climbers to have had a lifetime injury and 1.8 times (95% CI: 1.1-2.8) more likely to have had an injury in the last 12 mo. No difference in overuse injuries was found between specialization groups. CONCLUSIONS: Early specialization is common among youth climbers but was not associated with an increase in injuries. Late specialization was associated with a higher likelihood of having had a climbing injury in the last 12 mo and during an entire climbing career.

Upper Extremity Injuries in Rock Climbers: Diagnosis and Management.

Rock climbing places substantial stress on the upper extremities and can lead to unique injuries not common to other sports. With increasing popularity of the sport, hand surgeons are expected to see more patients with these pathologies. An understanding of the sport, accurate diagnoses, and appropriate treatment protocols are critical to maintain climbers' competitive abilities.

Review and Analysis of Mountaineering Accidents in the United States from 1947-2018.

DeLoughery, Emma P. and Thomas G. DeLoughery. Review and Analysis of Mountaineering Accidents in the United States from 1947-2018. High Alt Med Biol. 23:114-118, 2022. Introduction: Given the popularity of mountaineering, it is important to better understand accidents related to this sport. We undertook this review of accidents to better understand the demographics and locations involved in mountaineering accidents over 71 years. Methods: Data collected from "Accidents in North American Mountaineering" booklets from 1947 to 2018 included the date, state and location of the accident, sex and age of the victim, type of accident, injuries sustained, and distance fallen if a fall occurred. If at least 10 accidents occurred in an individual state and/or location, these sites were separately analyzed. Results: From 1947 to 2018, 2,799 people were reported to be involved in mountaineering accidents, and 43% of these accidents resulted in death. Women were involved in 12% of cases. Falls were the most common accident (68% incidence, 45% fatal), followed by falling rock (7%, 26% fatal), avalanche (6%, 75% fatal), and falling into a crevasse (2%, 52% fatal). The average age of victims was 30 years. California had the most accidents (18%), followed by Washington (16%) and Alaska (15%). Denali had the greatest frequency of both accidents and deaths (11%, 8% of deaths), followed by Mount Rainier (6%, 7% of deaths) and Mount Hood (2%, 3% of deaths). Conclusions: Accident victims tend to be young and predominantly male, and the accidents themselves are most often falls. Avalanches were identified as an accident cause with a high fatality rate.

Characteristics of bouldering injuries based on 430 patients presented to an urban emergency department.

INTRODUCTION: Bouldering is a climbing sport that has been attracting a greater number of recreational and professional athletes over recent decades, which has led to an increase in sport-related injuries. The aim of this study was to determine the characteristics and the types of acute injuries caused by bouldering. Further athlete-specific factors and covariates for the trauma types were investigated. MATERIALS AND METHODS: In this retrospective analysis, all patients presented to the level 1 trauma center at the hospital of the Technical University of Munich after an acute trauma related to bouldering were identified via the hospital documentation system. The period of observation was ten years, from 2010 until 2020. Epidemiological and injury-specific information as well as the initial treatment were registered. In a second step, the affected patients were invited to participate in an online survey in order to collect information about their skills, experience, and details about the trauma. RESULTS: A total of 430 patients with 447 acute injuries were identified. There were 244 injuries among female and 203 injuries among male patients. The most common anatomical region affected was ankle (36.7%), knee (16.8%), elbow (12.3%), spine (7.2%) and shoulder (6.3%). The majority of 273 (61.1%) injuries were located at the lower extremities. The most frequent types of injury were sprains (53.0%), fractures (22.8%) or joint dislocations (11.9%). Surgical treatment was necessary for 89 (19.9%) patients. A return to bouldering was more likely in male patients 50 (75.8%) than in females 47 (59.5%) (p = 0.038). Subjectively, inexperienced boulderers were also less likely to return to the sport than advanced boulderers with greater experience (p = 0.001) CONCLUSION: The incidence of bouldering injuries is rising. Typical bouldering injuries could be identified and quantified at least for those patients who were presented to a hospital emergency department. Injuries in this setting do differ from the injury types known from rock climbing injuries as they are located on the lower extremity more often. Injuries of the fingers and hand, which are common climbing injuries, have been barely encountered in the emergency center.

Injury Rates, Patterns, Mechanisms, and Risk Factors Among Competitive Youth Climbers in the United States.

INTRODUCTION: Competitive rock climbing is a fast-growing sport. Despite comprehensive reviews on adult climbing-related injuries, few pediatric-specific reviews exist, and studies exclusively on competitive youth climbers are needed. Objectives of this study include 1) estimating the injury rate (IR); 2) describing injury patterns and mechanisms; and 3) identifying injury risk factors in competitive youth climbers. METHODS: The study design was cross-sectional. Competitive youth climbers were included. Participants completed an anonymous questionnaire to document climbing injuries over the preceding 12 mo. Demographic data and data regarding injuries were collected. The IR was calculated. Analyses were performed to assess association between injury and multiple variables. Multivariate logistic regression was completed for significant variables to control for exposure time. RESULTS: The IR was 2.7 injuries per 1000 climbing hours. Hand/Finger injuries were most frequent; chronic overuse was the most common etiology. Injury severity was low overall. Risk factors significantly associated with climbing injury were climbing discipline (bouldering > sport/lead climbing), return to climbing while still in pain, finger taping, higher number of hours climbed per session and per year, climbing at higher bouldering difficulties, and unsupervised climbing. CONCLUSIONS: The IR in competitive youth climbers was found to be lower than previously reported but higher than suggested by adult studies or those that exclude chronic injuries. Findings are consistent with types, severity, and mechanisms reported in other studies. Modifiable risk factors, especially return to climbing while still injured, warrant further prospective investigation.

Pulley Rupture in Rock Climber after Collagenase Treatment for Dupuytren Contracture.

Pulley injuries and Dupuytren disease are quite common in rock climbing. We report a rock climber who was treated for a Dupuytren contracture with collagenase injection therapy. Two months later, he developed a traumatic pulley injury during climbing and was treated with a ring orthosis. However, the finger contracture deteriorated and both a recurrent pulley rupture and a second pulley rupture were diagnosed. We were unable to find any reports on the use of collagenase in rock climbers with Dupuytren disease. We report a case of pulley rupture in a rock climber, treated for Dupuytren contracture in the treated and an adjacent finger, 2 months after the injection of collagenase. Level of Evidence: Level V (Therapeutic).
