"Run-and-jump failure": new injury patterns in indoor bouldering.

In recent years, professional and non-professional bouldering have seen a fundamental change in movement patterns towards complex movement sequences. This is associated with increased demands on the musculoskeletal system, especially the lower extremities, which can lead to new injury patterns. In the course of our clinical work, we have already seen an increasing number of lower extremity injuries after run-and-jump sequences, with a severe one being highlighted in this case report.

Occupational Aspects of Alpine Helicopter Rescue Operations: Recommendation of the Medical Commission of the Union Internationale des Associations d'Alpinisme.

Helicopter rescue operations in the mountains or at high altitude are well-known as strenuous tasks often associated with some risk. However, there is no standardized procedure for preventive checkups of rescue personnel by occupational care professionals. Therefore, the Medical Commission of the International Climbing and Mountaineering Federation (UIAA MedCom) suggests the procedure presented in this study. This comprehensive recommendation is based on more than 2 decades of research of MedCom members and extensive literature search. A total of 248 references were selected by the committee as relevant for the topic. To keep the recommendation handy, the complete list is available as supplemental material (see online Supplemental Material). This article recommends standardized procedures for occupational screening and better health of search and rescue personnel.

Wrist Injuries in Climbers.

BACKGROUND: Acute and chronic injuries to the wrist are among the most common sport-related complaints of climbing athletes but have not been extensively evaluated in this population. Therefore, it is important to categorize climbing injuries to the wrist, analyze risk factors, and assess treatment outcomes. PURPOSE: To evaluate the distribution, outcomes, and influencing factors of wrist injuries in climbers. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Climbing athletes with wrist injuries who presented to our specialized sports medical center over the course of 4 years (2017-2020) were selected. All had prospectively completed questionnaires including their climbing-specific background (years of training, climbing level, training methods, etc). Injuries were analyzed (International Climbing and Mountaineering Federation [UIAA] grade and diagnosis), and treatment methods and outcomes were retrospectively assessed with a minimum follow-up of 2 years. Parameters included the climbing score, visual analog scale for pain score, Patient-Rated Wrist Evaluation (PRWE) score, and shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score including the sport component (DASH-Sport) score before and after treatment as well as time to return to climbing. RESULTS: A total of 69 patients (25 female, 44 male) with 78 wrist injuries were identified and analyzed. Of these, 7 injuries were bilateral, occurring at the same time, and 2 injuries were independent reinjuries to either the same or the contralateral side. In addition, 24 injuries (30.8%) were acute, while 54 (69.2%) were chronic. Overall, 2 injuries had a UIAA grade of 3; all others had a UIAA grade of 2. The most frequent injuries were synovitis of the ulnocarpal recess, ulnar impaction, bone marrow edema of the lunate, wrist sprains (joint capsular pain with stress, with no pathological finding on magnetic resonance imaging), and wrist ganglion cysts. Nonoperative treatment was performed for 61 of the injuries, while 17 were treated surgically. In 51 cases (65.4%), injuries healed without consequences; in 27 cases (34.6%), discomfort remained. The visual analog scale pain score decreased from 4.8 ± 1.9 before treatment to 0.7 ± 1.0 after treatment (P < .001), the PRWE score decreased from 53.6 ± 24.9 to 10.3 ± 13.1 (P < .001), the QuickDASH score improved from 53.0 ± 16.6 to 20.0 ± 20.2 (P < .001), and the DASH-Sport score improved from 82.0 ± 16.1 to 38.1 ± 23.5 (P < .001). The climbing score improved from 2.5 ± 1.1 to 4.3 ± 1.0 points (P < .001). The patient-reported number of days with pain was negatively correlated with changes in the PRWE score (r = -0.351; P < .001), QuickDASH score (r = -0.316; P = .007), and climbing score (r = -0.264; P = .025) as well as the number of days without climbing (r = -0.266; P = .025). The number of days without climbing was positively correlated with changes in the PRWE score (r = 0.369; P < .001). CONCLUSION: Wrist injuries in climbers constituted a diverse set of diagnoses. Ulnar-sided injuries were most common, and many patients had >1 diagnosis. Outcomes for all treatment methods (surgery and nonoperative care) were favorable, but approximately one-third of climbers had persistent wrist discomfort after treatment, underscoring the need for accurate diagnoses and acute and expert care.

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.

Functional and Sport-Specific Outcome Following Traumatic First-Time Shoulder Dislocation and Arthroscopic Surgical Repair in Rock Climbers.

INTRODUCTION: Traumatic shoulder dislocations rank among the most common shoulder injuries in climbers, with rising numbers over the last years. The objective of this study was to analyze the outcome following traumatic first-time shoulder dislocation and subsequent surgical treatment in this population. METHODS: In a retrospective study, climbers who experienced a traumatic shoulder dislocation were treated with an arthroscopic repair of the labrum-ligament complex (LLC). The functional outcome was assessed with a standardized questionnaire and clinical examination, including the Constant Murley and Single Assessment Numeric Evaluation scores. The sport-specific outcome was analyzed using the Union Internationale des Associations d'Alpinisme (UIAA) scale of difficulty and a sport-specific outcome score. RESULTS: The functional and sport-specific outcome for 27 climbers (20 men; 7 women; 3 with bilateral injuries; age, 34±11 [17-61] y; data presented as mean±SD [range]) was assessed 53±29 (12-103) mo after surgery. The postoperative Constant Murley score was 95±8 (67-100) points. At follow-up, 93% (n=25) of patients had started climbing again. Twenty-one climbers (78%) reached a climbing level within the range of ±0.33 UIAA grades of their initial capability or even exceeded their preinjury grade. Only 7% (n=2) of the patients had a recurrent shoulder dislocation, leading to a secondary surgery, and, therefore, required ongoing postoperative treatment at the time of follow-up. CONCLUSIONS: Arthroscopic repair of the LLC following first-time traumatic shoulder dislocation in climbers shows a good outcome and a low recurrence rate. After surgery, most patients are able to regain a high level of rock-climbing ability.

High-resolution ultrasound tendon-to-bone distances in partial and complete finger flexor A2 pulley ruptures simulated in human cadaver dissection: toward understanding imaging of partial pulley ruptures.

Introduction: The A2 pulley tear is the most common injury in rock climbing. Whereas complete A2 pulley ruptures have been extensively researched, studies focused on partial A2 pulley ruptures are lacking. A2 pulleys rupture distally to proximally. High-resolution ultrasound imaging is considered the gold-standard tool for diagnosis and the most relevant ultrasound measurement is the tendon-to-bone distance (TBD), which increases when the pulley ruptures. The purpose of this study was to establish tendon-to-bone distance values for different sizes of partial A2 pulley ruptures and compare these values with those of complete ruptures. Material and methods: The sample consisted of 30 in vitro fingers randomly assigned to 5 groups: G1, no simulated tear (control); G2, simulated 5 mm tear (low-grade partial rupture); G3, simulated 10 mm tear (medium-grade partial rupture); G4, simulated 15 mm tear (high-grade partial rupture); and G5, simulated 20 mm or equivalent tear (complete rupture). A highly experienced sonographer blinded to the randomization process and dissections examined all fingers. Results: The tendon-to-bone distance measurements (medians and interquartile ranges) were as follows: G1, 0.95 mm (0.77-1.33); G2, 2.11 mm (1.78-2.33); G3, 2.28 mm (1.95-2.42); G4, 3.06 mm (2.79-3.28); and G5, 3.66 mm (3.55-4.76). Significant differences were found between non-torn pulleys and simulated partial and complete pulley ruptures. Discussion: In contrast, and inconsistent with other findings, no significant differences were found among the different partial rupture groups. In conclusion, the longer the partial pulley rupture, the higher the tendon-to-bone distance value. The literature is inconsistent regarding the tendon-to-bone distance threshold to diagnose a partial A2 pulley rupture. The minimum tendon-to-bone distance value for a partial rupture was 1.6 mm, and tendon-to-bone distance values above 3 mm suggest a high-grade partial pulley rupture (15 mm incision) or a complete pulley rupture.

Exercise Resistance Band induced injuries during Covid 19 Pandemic Lockdown Training.

The COVID-19 (coronavirus disease 2019) pandemic forces athletes to perform their workout at home with alternative training methods. Exercise resistance bands, often used for this purpose, can cause damage when they recoil or tear. Potentially resulting injuries include bruises, head injuries, lacerations, facial fractures and eye injuries. The following article presents two case reports including accident mechanism, injuries, diagnostic evaluation and treatment.The first patient presented with an open depressed skull fracture caused by a recoiling exercise resistance band, while the second patient sustained a complex ocular trauma caused by a tearing exercise resistance band when performing supported chin-ups.

Ski Mountaineering-Scientific Knowledge of This New Olympic Sport: A Narrative Review.

ABSTRACT: Ski mountaineering (skimo) has been accepted as a new sport for the 2026 Milan-Cortina Olympics. The equipment used in this competitive ski mountaineering varies from leisure ski mountaineering equipment mainly in one point: the minimal weight. At the elite athlete level, skimo demands both maximal endurance performance and a high-intensity anaerobic capacity for the sprint and vertical races. Race time significantly correlates to V˙O2max, body mass index and racing gear mass. Available literature only rarely comments on competitive skimo injuries. Injuries are not only due to falls in downhill skiing but also can result from external hazards, such as avalanches and cold. The high training load of athletes in combination with a low body weight, low body fat, and exposure to cold cause high rates of respiratory infections in athletes. The inclusion of skimo into the Olympic program is expected to result in certain changes, such as higher training loads for the athletes and increased scientific interest into training methods.

Acute and Chronic Injury Patterns in Competitive Paraclimbing Sports.

OBJECTIVE: This is the first study to evaluate sport-related injuries in competitive Paraclimbing athletes with the aim of creating a medical database for future research on injury prevention. DESIGN: This was a descriptive epidemiology study. Data collection took place in two parts. In the first part, an online survey ( n = 81) was conducted. The second part was undertaken during three competitions ( n = 273) of the 2021 International Federation of Sport Climbing Paraclimbing competitions. Injury severity grading was determined using the Climbing Injury Score of the International Federation of Sport Climbing. RESULTS: In the online survey, 76 injuries were reported: 62% acute and 38% chronic injuries. Injury severity was as follows: 21 scored 1, 34 scored 2a, 19 scored 2b, and 2 scored 3. The most injured body regions were the upper extremity (66%) with shoulder injuries (29%) most common; 53% reported regular pain/discomfort during training/competition and 16% used nonsteroidal anti-inflammatory drugs regularly to prevent pain/discomfort when training. In the 2021 International Federation of Sport Climbing Paraclimbing competitions, eight injuries were recorded. Injury severity was as follows: seven scored 1 and one scored 2a. The most injured body region was the upper extremity (47%). Overall, the calculated climbing time was 975 hrs, and injury incidence risk was 8.21 per 1000 hrs. CONCLUSION: Compared with nondisabled climbers, the injury pattern seems to be sport dependent but influenced by the unique impairments of the athletes. In Paraclimbing competitions, the injury severity is mostly mild, with an overall low injury incidence. A concern is the number of athletes with pain/discomfort during training/competition with regular nonsteroidal anti-inflammatory drug intake.

UIAA Medical Commission Recommendations for Mountaineers, Hillwalkers, Trekkers, and Rock and Ice Climbers with Diabetes.

Hillebrandt, David, Anil Gurtoo, Thomas Kupper, Paul Richards, Volker Schöffl, Pankaj Shah, Rianne van der Spek, Nikki Wallis, and Jim Milledge. UIAA Medical Commission recommendations for mountaineers, hillwalkers, trekkers, and rock and ice climbers with diabetes. High Alt Med Biol. 24: 110-126.-The object of this advice article is not only to give the diabetic mountaineer general guidance but also to inform his or her medical team of practical aspects of care that may not be standard for nonmountaineers. The guidelines are produced in seven sections. The first is an introduction to the guidelines, and the second is an introduction to this medical problem and is designed to be read and understood by diabetic patients and their companions. The third section is for use in an emergency in mountains. The fourth is for rock, ice, and competition climbers operating in a less remote environment. These initial sections are deliberately written in simple language. The fifth and sixth sections are written for clinicians and those with skills to read more technical information, and the seventh looks at modern technology and its pros and cons in diabetes management in a remote area. Sections One and Two could be laminated and carried when in the mountains, giving practical advice.

Cardiovascular Risk Profiles and Pre-Existing Health Conditions of Trekkers in the Solu-Khumbu Region, Nepal.

BACKGROUND: High-altitude tourist trekking continues to grow in popularity on the Everest Trek in Nepal. We examined which pre-existing cardiovascular and health conditions these global trekkers had and what health issues they encountered during the trek, be it exacerbations of pre-existing conditions, or new acute ones. METHOD: Trekkers (n = 350) were recruited from guesthouses along the Everest Trek, mostly at Tengboche (3860 m). After completing a questionnaire on their health and travel preparation, they underwent a basic physical examination with an interview. RESULTS: Almost half (45%) had pre-existing conditions, mostly orthopaedic and cardiovascular diseases. The average age was 42.7 years (range 18-76). The average BMI was 23.4 kg/m2, but 21% were overweight. A third were smokers (30%), and 86% had at least one major cardiovascular risk factor. A quarter (25%) were suffering from manifest acute mountain sickness (AMS), and 72% had at least one symptom of AMS. Adequate pre-travel examination, consultation, and sufficient personal preparation were rarely found. In some cases, a distinct cardiovascular risk profile was assessed. Hypertensive patients showed moderately elevated blood pressure, and cholesterol levels were favourable in most cases. No cardiovascular emergencies were found, which was fortunate as timely, sufficient care was not available during the trek. CONCLUSION: The results of earlier studies in the Annapurna region should be revalidated. Every trekker to the Himalayas should consult a physician prior to departure, ideally a travel medicine specialist. Preventative measures and education on AMS warrant special attention. Travellers with heart disease or with a pronounced cardiovascular risk profile should be presented to an internal medicine professional. Travel plans must be adjusted individually, especially with respect to adequate acclimatisation time and no physical overloading. With these and other precautions, trekking at high altitudes is generally safe and possible, even with significant pre-existing health conditions. Trekking can lead to invaluable personal experiences. Since organized groups are limited in their flexibility to change their itinerary, individual trekking or guided tours in small groups should be preferred.

The Energetic Costs of Uphill Locomotion in Trail Running: Physiological Consequences Due to Uphill Locomotion Pattern-A Feasibility Study.

The primary aim of our feasibility reporting was to define physiological differences in trail running (TR) athletes due to different uphill locomotion patterns, uphill running versus uphill walking. In this context, a feasibility analysis of TR athletes' cardiopulmonary exercise testing (CPET) data, which were obtained in summer 2020 at the accompanying sports medicine performance center, was performed. Fourteen TR athletes (n = 14, male = 10, female = 4, age: 36.8 ± 8.0 years) were evaluated for specific physiological demands by outdoor CPET during a short uphill TR performance. The obtained data of the participating TR athletes were compared for anthropometric data, CPET parameters, such as V˙Emaximum, V˙O2maximum, maximal breath frequency (BFmax) and peak oxygen pulse as well as energetic demands, i.e., the energy cost of running (Cr). All participating TR athletes showed excellent performance data, whereby across both different uphill locomotion strategies, significant differences were solely revealed for V˙Emaximum (p = 0.033) and time to reach mountain peak (p = 0.008). These results provide new insights and might contribute to a comprehensive understanding of cardiorespiratory consequences to short uphill locomotion strategy in TR athletes and might strengthen further scientific research in this field.

Companion Rescue and Risk Management of Trekkers on the Everest Trek, Solo Khumbu Region, Nepal.

BACKGROUND: Trekking to high-altitude locations presents inherent health-related hazards, many of which can managed with specific first aid (FA) training. This study evaluates the trip preparation, FA knowledge, and FA self-assessment of trekkers (organized by tour operators vs. individually planned tours). Data obtained shall be used for specific FA trip preparation and management of emergencies en route for this population. METHODS: A total of 366 trekkers on the Everest Base Camp Trek, Nepal, were interviewed using a questionnaire specifically designed to evaluate their FA knowledge and management of emergencies. Data evaluation was performed using descriptive statistics. RESULTS: A total of 40.5% of trekkers experienced at least one medical incident during their trip, of which almost 50% were due to acute mountain sickness (AMS). There was more AMS in commercially organized groups than in individually planned ones (55% vs. 40%). For more than 50%, no medical care was available during their trip. A total of 80% could answer only 3/21 FA questions completely correctly. Only 1% showed adequate knowledge concerning FA strategies. A total of 70% were willing to enroll in an FA class specialized towards the needs of trekkers. CONCLUSIONS: The importance of high-altitude FA knowledge and trip preparation is widely underestimated. There is an unmet demand amongst trekkers for specific wilderness FA classes.

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.

Left Ventricular, Left Atrial and Right Ventricular Strain Modifications after Maximal Exercise in Elite Ski-Mountaineering Athletes: A Feasibility Speckle Tracking Study.

Eleven world elite ski-mountaineering (Ski-Mo) athletes were evaluated for pronounced echocardiographic physiological remodeling as the primary aim of our feasibility speckle tracking study. In this context, sports-related cardiac remodeling was analyzed by performing two-dimensional echocardiography, including speckle tracking analysis of the left atrium (LA), right ventricle (RV) and left ventricular (LV) global longitudinal strain (LV-GLS) at rest and post-peak performance. The feasibility echocardiographic speckle tracking analysis was performed on eleven elite Ski-Mo athletes, which were obtained in 2022 during the annual medical examination. The obtained data of the professional Ski-Mo athletes (11 athletes, age: 18-26 years) were compared for different echocardiographic parameters at rest and post-exercise. Significant differences were found for LV-GLS mean (p = 0.0036) and phasic LA conduit strain pattern at rest and post-exercise (p = 0.0033). Furthermore, negative correlation between LV mass and LV-GLS (p = 0.0195, r = -0.69) and LV mass Index and LV-GLS (p = 0.0253, r = -0.66) at rest were elucidated. This descriptive reporting provided, for the first time, a sport-specific dynamic remodeling of an entire elite national team of the Ski-Mo athlete's left heart and elucidated differences in the dynamic deformation pattern of the left heart.

Prevalence of amenorrhea in elite female competitive climbers.

Elite competitive sport climbers exhibit a high strength-to-weight ratio and are reported in the literature to be lighter and leaner than their athletic counterparts. Current research regarding nutrition among climbers is sparse but suggests that they may be at high risk for low energy availability and Relative Energy Deficiency in Sport (RED-S). The prevalence of amenorrhea, one of the primary indicators of RED-S, is unknown in this athletic population. The purpose of this study was to determine the prevalence of current (previous 12 months) amenorrhea among elite level competitive sport climbers. Methods: An anonymous online survey was distributed via email to 1,500 female climbers registered as competitors within the International Federation of Sport Climbing to assess the prevalence of amenorrhea over the past 12 months. Results: A total of 114 female sport climbers answered all survey questions regarding menstrual function and 18 athletes (15.8%) presented with current amenorrhea. The majority of the athletes (72%; n = 82) were categorized with eumenorrhea. An additional 14 athletes (12.3%) provided information that indicated irregular cycles, but answers to all menstrual cycle questions were not congruent to elicit a classification of amenorrhea and these athletes were categorized with a menstrual status of unsure. The average BMI for climbers with eumenorrhea was 20.8 ± 1.8 kg/m2 and 19.9 ± 2.4 kg/m2 for those with amenorrhea. A higher percentage of climbers with amenorrhea revealed they currently struggle with an eating disorder compared to those without amenorrhea (13.5 vs. 22.2%, respectively). Conclusion: This study indicates that some female climbers competing at the World Cup level do have menstrual disturbances with relatively normal BMIs and some currently struggle with one or more eating disorders. Even though World Cup competitions use BMI critical margins to screen competitors, this research highlights the need for more medical supervision of competitive elite female sport climbers in order to protect their overall health, including menstrual function. Further research is required to clarify how many climbers suffer from endocrine abnormalities related to RED-S. With more scientific evidence in this area practitioners will be better equipped to educate the athlete and coach with evidence-based nutrition recommendations.

Physiological Effects of Training in Elite German Winter Sport Athletes: Sport Specific Remodeling Determined Using Echocardiographic Data and CPET Performance Parameters.

Nine ski mountaineering (Ski-Mo), ten Nordic-cross country (NCC), and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance and pronounced echocardiographic physiological cardiac remodeling as a primary aim of our descriptive preliminary report. In this context, a multicenter retrospective analysis of two-dimensional echocardiographic data including speckle tracking of the left ventricle (LV-GLS) and CPET performance analysis was performed in 31 elite world winter sports athletes, which were obtained during the annual sports medicine examination between 2020 and 2021. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18-32 years) were compared for different CPET and echocardiographic parameters, anthropometric data, and sport-specific training schedules. Significant differences could be revealed for left atrial (LA) remodeling by LA volume index (LAVI, p = 0.0052), LV-GLS (p = 0.0003), and LV mass index (LV Mass index, p = 0.0078) between the participating disciplines. All participating athletes showed excellent performance data in the CPET analyses, whereby significant differences were revealed for highest maximum respiratory minute volume (VE maximum) and the maximum oxygen pulse level across the participating athletes. This study on sport specific physiological demands in elite winter sport athletes provides new evidence that significant differences in CPET and cardiac remodeling of the left heart can be identified based on the individual athlete's training schedule, frequency, and physique.

Physiological Aspects of World Elite Competitive German Winter Sport Athletes.

Nine Ski mountaineering (Ski-Mo), ten Nordic-Cross Country (NCC) and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance as the primary aim of our descriptive preliminary report. A multicenter retrospective analysis of CPET data was performed in 31 elite winter sports athletes, which were obtained in 2021 during the annual medical examination. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18-32 years) were compared for different CPET parameters, and athlete's physique data and sport-specific training schedules. All athletes showed, as estimated in elite winter sport athletes, excellent performance data in the CPET analyses. Significant differences were revealed for VE VT2 (respiratory minute volume at the second ventilatory threshold (VT2)), highest maximum respiratory minute volume (VEmaximum), the indexed ventilatory oxygen uptake (VO2) at VT2 (VO2/kg VT2), the oxygen pulse at VT2, and the maximum oxygen pulse level between the three professional winter sports disciplines. This report provides new evidence that in different world elite winter sport professionals, significant differences in CPET parameters can be demonstrated, against the background of athlete's physique as well as training control and frequency.
