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.

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.

Primary Periphyseal Stress Injuries in Young Athletes: A Systematic Review.

BACKGROUND: Overuse injuries are common in sporting children and adolescents. These injuries are a particular concern when they involve the epiphyseal-physeal-metaphyseal (EPM) complex given their potential to disturb skeletal growth. Specifically, the limits of mechanical tolerance of the EPM complex to repetitive stress may be exceeded by the intense and continuous training characteristic of many youth sports today. OBJECTIVE: This article describes the present status of knowledge on the occurrence and outcome of primary periphyseal stress injuries (PPSIs) affecting the EPM complex in the extremities of children and adolescents involved in youth sports. METHODS: A comprehensive review of the sports medicine literature was conducted to determine the nature and extent of PPSIs affecting the EPM complex of the extremities among youth sports participants and the potential for consequent skeletal growth disturbance and resultant limb deformity associated with these injuries. RESULTS: Our initial search uncovered 128 original published scientific articles reporting relevant data on PPSIs. There were 101 case reports/series, 19 cross-sectional, 1 case-control, and 7 cohort studies with relevant data. The case reports/series studies reported 448 patients with PPSIs involving the extremities. Children and adolescents representing a variety of high impact repetitive youth sports activities-including baseball, badminton, climbing, cricket, dance, gymnastics, rugby, soccer, swimming, tennis, and volleyball-may sustain PPSIs involving the shoulder, elbow, hand and wrist, knee, and ankle and foot. Although incidence data from prospective cohort studies are lacking, data arising from cross-sectional studies suggest that PPSIs may be common in select groups of youth athletes-including the shoulder in baseball players (0-36.6%), wrist in gymnasts (10-83%) and platform divers (52.6%), and fingers in rock climbers (5-58%). Notably, not all stress-related skeletal changes detected on imaging were symptomatic in these studies. When diagnosed and treated with an appropriate period of rest and rehabilitation, most patients studied were able to return to their sport activities. However, our data also show that 57/448 PPSIs (12.7%) produced growth disturbance, and that 28/448 patients (6.2%) underwent surgery for their injuries. Absence of treatment, delayed presentation and diagnosis, and non-compliance with a rest regimen were common in cases that produced growth disturbance. CONCLUSIONS: PPSIs may affect the extremities of children and adolescents engaged in a variety of youth sports, especially at advanced levels of training and competition. Most skeletally immature patients with PPSIs respond well to timely treatment; however, in extreme cases, PPSIs can progress to produce skeletal growth disruption which may necessitate surgical intervention. Clearly, establishing the early diagnosis of PPSIs and providing timely treatment of these injuries are needed to ensure the skeletal health of youth sports participants. Rigorous prospective longitudinal epidemiological and imaging studies designed to provide incidence rates of PPSIs and to determine the effect of PPSIs on long-term skeletal health are also necessary.

Rupture of the Short Head of the Biceps Brachii Muscle Belly Caused by a Rock-Climbing Accident.

The case of a 42-y-old rock climber who sustained a complete, isolated rupture of the short head of the biceps brachii muscle after falling onto his upper arm while bouldering is presented. This is the first description of this rare injury after a climbing accident. Moreover, there is no definitive consensus on whether and when surgical intervention is necessary in such a case. We performed a direct end-to-end suture of the muscle belly through an open surgical approach. Postoperatively, we performed a detailed follow-up, including clinical examinations and sonography and magnetic resonance imaging to check the integrity of the suture. After 6 mo, our patient had regained a full range of motion without functional complaints or pain. Concerning the sports-specific outcome, we only found a slight decrease in rock-climbing abilities (Union Internationale des Associations d'Alpinisme Scale of Difficulty grade VII+ postsurgery compared to VIII preinjury). In conclusion, we suggest that early surgical reapproximation of the muscle belly might be the best treatment option for this severe but rare injury in athletes.

Compartment Syndrome of the Foot: An Evidence-Based Review.

Compartment syndrome of the foot (CSF) is a surgical emergency, with high risk of morbidity and poor outcome, including persistent neurologic deficits or amputation. Uncertainty remains regarding surgical approaches, pressure monitoring values, and the extent of surgical treatment. This review provides a summary of the current knowledge and reports evidence-based diagnostic and therapeutic management options for CSF. Articles describing CSF were identified from MEDLINE, PubMed, and Cochrane databases up until February 2018. Experimental and original articles, systematic and nonsystematic reviews, case reports, and book chapters, independent of their level of evidence, were included. Crush injuries are the leading cause of CSF, but CSF can present after fractures of the tarsal or metatarsal bones and dislocations of the Lisfranc or Chopart joints. CSF is often associated with persistent neurologic deficits, claw toes, amputations, and skin healing problems. Diagnosis is made after accurate clinical evaluation combined with intracompartmental pressure monitoring. A threshold value of <20 mmHg difference between the diastolic blood pressure and the intracompartmental pressure is considered diagnostic. Management consists of surgery, whereby 2 dorsal incisions are combined with a medioplantar incision to the calcaneal compartment. The calcaneal compartment can serve as an "indicator compartment," as the highest-pressure values can regularly be measured within this compartment. Appropriately powered studies of CSF are necessary to further evaluate and compare diagnostic and therapeutic options.

Lumbrical muscle tear: clinical presentation, imaging findings and outcome.

The incidence of lumbrical muscle tear is increasing due to the popularity of climbing sport. We reviewed data from 60 consecutive patients with a positive lumbrical stress test, including clinical examination, ultrasound and clinical outcomes in all patients, and magnetic resonance imaging in 12 patients. Fifty-seven patients were climbers. Lumbrical muscle tears were graded according to the severity of clinical and imaging findings as Grade I-III injuries. Eighteen patients had Grade I injuries (microtrauma), 32 had Grade II injuries (muscle fibre disruption) and 10 had Grade III injuries (musculotendinous disruption). The treatment consisted of adapted functional therapy. All patients completely recovered and were able to return to climbing. The healing period in Grade III injuries was significantly longer than in the patients with Grade I or II injuries ( p < 0.001). We recommend evaluation of specific clinical and imaging findings to grade the injuries and to determine suitable therapy. LEVEL OF EVIDENCE: IV.

Feasibility of a New Pulley Repair: A Cadaver Study.

PURPOSE: In this study, the feasibility of a new pulley reconstruction in which the tendon graft is pulled through a tunnel in the proximal phalanx, was evaluated using a cadaver model, with particular attention paid to the weakening of the bone structure by the drill hole. METHODS: Nine fingers from 6 cadaver hands with intact pulley systems were compared with 9 fingers from 6 cadaver hands with missing A2 to A4 pulleys but that included a repair using the new surgical technique. Each finger was fixed to an isokinetic loading device. The forces in the flexor tendons were recorded in each finger using a force transducer. RESULTS: The forces recorded in the flexor tendons of the control group were significantly higher than in the reconstructed fingers. The most common event in the reconstructed fingers was graft failure. A fracture of the bone due to the drill hole was not observed. CONCLUSIONS: The new pulley reconstruction could represent an alternative to existing reconstructive techniques. The cause for the higher forces recorded in the control group could be attributed to sutures used in the operated fingers. CLINICAL RELEVANCE: The new pulley reconstruction method may enable reduced extensor tendon irritation because it avoids contact with the extensor hood and could possibly prohibit cortical bone loss, a serious side effect in the "one and one-half loop" technique.

Rock Climbing-Related Bone Marrow Edema of the Hand: A Follow-up Study.

OBJECTIVE: Sport climbers strain passive and active anatomical structures of their hands and fingers to the maximum during training or competition. This study was designed to investigate bone marrow edema (BME) in rock climbing athletes. DESIGN: Systematic detection, treatment, and follow-up investigation of rock climbing athletes with BME of the hand. SETTING: Primary-level orthopedic surgery and sports medicine division of a large academic medical center. PATIENTS: Thirty-one high-level climbers with diffuse pain in the hand and wrist joint caused by rock climbing were included in this study. INTERVENTIONS: The therapy consisted of consequent stress reduction and a break from sports. MAIN OUTCOME MEASURES: Reduction of BME shown through magnetic resonance imaging (MRI) and regaining of preinjury climbing levels (Union Internationale des Associations d' Alpinisme metric scale). RESULTS: In 28 patients, MRI revealed osseous edema because of overload at the respective area of interest, mainly in the distal radius, the distal ulna, or the carpal bones, which could not be otherwise diagnosed as inflammations, tumors, or injuries. We classified these edemas and fractures of the hamate because of overload. The edema was a stress reaction to highly intensive training and climbing with presumably high traction to the wrist area. The control MRIs demonstrated that even with a consequent stress reduction, the edemas required 3 to 4 months to disappear completely. CONCLUSIONS: Climbers with nonspecific, diffuse pain in the wrist and/or the fingers should be examined with MRI to detect or exclude the diagnosis of a BME.

Functional and Sports-Specific Outcome After Surgical Repair of Rotator Cuff Tears in Rock Climbers.

OBJECTIVE: The purpose of this study was to analyze the general (Constant Murley score) and sports-specific (change in International Climbing and Mountaineering Federation [UIAA] grade) outcome after surgical repair of rotator cuff injuries in rock climbers. METHODS: In a retrospective study, 12 rock climbers (10 men, 2 women; age 55 years; SD±9; range 28-66 years [mean±SD with range] with rotator cuff lesions were re-evaluated 27±16 (12-72) months after arthroscopic surgical repair of the rotator cuff of the shoulder. The etiology of the rotator cuff pathology was equally chronic (age 61±12 [28-66] years) and acute (age 53±5 [51-65] years). The postoperative general outcome, including the Constant Murley score, was assessed with a standardized questionnaire and clinical examination. The postoperative sports-specific outcome was analyzed using the UIAA metric scale. RESULTS: The postoperative Constant Murley score was 92±7 (80-98). All participants had already started climbing again; 11 of 12 climbers regained a climbing level within ±1.33 UIAA metric grades of their initial capability. CONCLUSION: Arthroscopic repair of acute and chronic rotator cuff tears shows a good functional outcome, enabling most patients to regain a high level of rock climbing ability.

Superior labral anterior posterior lesions of the shoulder: Current diagnostic and therapeutic standards.

Surgical treatment of superior labral anterior posterior (SLAP) lesion becomes more and more frequent which is the consequence of evolving progress in both, imaging and surgical technique as well as implants. The first classification of SLAP lesions was described in 1990, a subdivision in four types existed. The rising comprehension of pathology and pathophysiology in SLAP lesions contributed to increase the types in SLAP classification to ten. Concerning the causative mechanism of SLAP lesions, acute trauma has to be differed from chronic degeneration. Overhead athletes tend to develop a glenohumeral internal rotation deficit which forms the basis for two controversial discussed potential mechanisms of pathophysiology in SLAP lesions: Internal impingement and peel-back mechanism. Clinical examination often remains unspecific whereas soft tissue imaging such as direct or indirect magnetic resonance arthrography has technically improved and is regarded to be indispensable in detection of SLAP lesions. Concomitant pathologies as Bankart lesions, rotator cuff tears or perilabral cysts should be taken into consideration when planning a personalized therapeutic strategy. In addition, normal variants such as sublabral recess, sublabral hole, Buford complex and other less common variants have to be distinguished. The most frequent SLAP type II needs a sophisticated approach when surgical teatment comes into consideration. While SLAP repair is considered to be the standard operative option, overhead athletes benefit from a biceps tenodesis because improved patient-reported satisfaction and higher rate of return to pre-injury level of sports has been reported.

Matrix-associated autologous chondrocyte transplantation combined with iliac crest bone graft for reconstruction of talus necrosis due to villonodular synovitis.

We report the case of a 24-year-old driving instructor with osteonecrosis of the talus and a large articular cartilage and osseous defect. The cystic lesion was caused by villonodular synovitis. After magnetic resonance imaging detection and arthoscopic analysis, the defect was filled with a bone graft, followed by matrix-associated autologous chondrocyte transplantation (MACT) combined with a total synovectomy. In general, lesions similar to the one described in this case are treated using osteochondral autografts, but in our case the osseous defect was too large to perform an osteochondral autograft. Our choice of treatment with an iliac crest bone graft combined with a MACT simultaneously has not yet been published, as far as we know. The patient returned to his former activities of daily living and sport activities, without restrictions or complaints, and with only a slight deficit in range of motion. Morphological and biochemical magnetic resonance imaging 12 months after surgery showed excellent bone healing with no intraosseous edema. The MACT resulted in a good clinical outcome, with 100% defect filling and excellent integration and surface and signal intensity of the cartilage repair tissue, and the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot score increased from 47 to 79 points.

Flap irritation phenomenon (FLIP): etiology of chronic tenosynovitis after finger pulley rupture.

After a pulley rupture, most climbers regain the full function of their previously uninjured fingers. However, in some cases of pulley rupture, a persistent inflammation of the tendon sheath is observed. In this study, 16 cadaver fingers were loaded until pulley rupture and then studied for the rupturing mechanism. In addition, two patients with this pathology were investigated using ultrasound and MRI, and received surgery. In 13 fingers, a rupture of one or several pulleys occurred and almost always at the medial or lateral insertion. In one finger, a capsizing of the pulley underneath the intact tendon sheath was observed, leading to an avulsion between tendon and tendon sheath. A similar pathology was observed in the ultrasound imaging, in MRI, and during surgery in two patients with prolonged recovery after minor pulley rupture. In cases of prolonged tenosynovitis after minor pulley rupture, a capsizing of the pulley stump is probably the cause for constant friction leading to inflammation. In those cases, a surgical removal of the remaining pulley stump and sometimes a pulley repair may be necessary.

Superior labral anterior-posterior lesions in rock climbers­primary double tenodesis?

OBJECTIVE: Shoulder problems, especially SLAP (superior labral anterior-posterior) lesions, are frequent in rock climbers. Although various SLAP repair methods demonstrate 75% to 97% good functional outcomes in general population, the results in overhead athletes are inconsistent and the question whether a primary tenodesis is more efficient arises. DESIGN: Prospective cohort study. SETTING: The patients were treated as inpatient surgical patients, and the follow-up was performed after 6 months and 2 years. PATIENTS: Six high-level rock climbers with SLAP lesions and degeneration of the long biceps tendon anchor or additional pulley lesions were surgically treated with primary tenodesis. INTERVENTIONS: Primary tenodesis was performed for SLAP lesions in high-level climbers. MAIN OUTCOME MEASURES: The postoperative outcome was assessed through physical examination after 6 months and 2 years, Constant-Murley score, re-establishment of initial climbing ability level, and self-perception of the function of the shoulder and climbing ability. RESULTS: All climbers regained their initial climbing level after 6 months. The Constant-Murley score (mean, 97.3%) showed an excellent functional outcome. The self-perception of the shoulder function and climbing ability was 96.8% of normal. CONCLUSIONS: The primary biceps tenodesis is proved to be a reliable alternative to arthroscopic SLAP repair in overhead athletes, especially if constant microtrauma persists.

A simple and effective implant for displaced fractures of the greater tuberosity: the "Bamberg" plate.

Displaced fractures of the greater tuberosity are common findings in trauma surgical patients. Nevertheless, osteosynthesis of these fractures impairs the risk of secondary dislocation or secondary impingement due to the implant (e.g., 4.5 mm cancellous screws with spiked washers). We present an easy and simple technique/implant to perform an osteosynthesis of multiple-fractured greater tuberosity fractures. We use a self-adjusted calcaneus titanium plate (Litos) which is cut into a 6 or more holed small plate. In ten patients we had excellent postoperative outcomes with no complications and no secondary loss of reduction. The surgical technique is easy and efficient.

Extensor hood syndrome--osteophytic irritation of digital extensor tendons in rock climbers.

OBJECTIVE: Injuries to the flexor tendons and flexor tendon pulleys are frequently reported in rock climbers. Osteoarthritic changes with bone spurs are also well known. We report on the less commonly described extensor tendon irritation caused by such osteophytes. METHODS: Thirteen high-level rock climbers (12 men, 1 woman; average age 33.8 years [range 17-55]; average years of climbing experience 19 [range 5-30]; average climbing level 10.2) with extensor hood irritation caused by dorsally located osteophytes of proximal interphalangeal (n = 10) or distal interphalangeal joints (n = 3) were evaluated and managed. Twelve climbers received conservative therapy and 1 climber was treated surgically. RESULTS: Before treatment, the climbers were unable to achieve their normal climbing ability due to extensor tendon irritations with resultant effusion noted in the ultrasound examinations. After conservative treatment, and in 1 case surgery, all patients achieved their previous climbing ability. CONCLUSION: While all climbers were able to achieve their former climbing level after treatment, the condition is progressive and the osteoarthritic changes will likely cause further problems for these individuals in the future. Extensor hood irritation must be considered in the differential diagnosis of finger pain in rock climbers.

Closed flexor pulley injuries in nonclimbing activities.

Closed flexor pulley injuries have been reported in rock climbers. We report 6 digital flexor pulley injuries in 6 patients aged 5 to 73 years that were not associated with a climbing injury. Excellent outcomes were achieved through conservative therapy in 5 patients and surgical therapy in 1 patient.

Injuries to the finger flexor pulley system in rock climbers: current concepts.

Closed traumatic ruptures of finger flexor tendon pulleys began to be recognized specifically over the past several decades. This injury, although rare in the general population, is seen more commonly in rock climbers. This article analyzes this type of injury and the current diagnostic and therapeutic criteria. Ultrasound and magnetic resonance imaging are used to differentiate between a pulley strain, partial rupture, complete rupture, or multiple ruptures. Grade I to III injuries (strains, partial rupture, single ruptures) are treated conservatively with initial immobilization and early functional therapy under pulley protection. Grade IV injuries (multiple ruptures) require surgical repair.

Biomechanical model for the determination of the forces acting on the finger pulley system.

A mathematical model proposed by Hume et al., 1991. Journal of Hand Surgery-American Volume 16, 722-730 for the determination of the forces acting on the A2 and A4 pulley was used. The parameters necessary for this determination include the angle of flexion, the positioning of the pulley with respect to the centre of rotation in the proximal interphalangeal joint (PIP), the relative mismatch between bone and tendon width at the location of the respective pulleys as well as the tendon height at this position. This model was further developed to include the stiffness of the respective pulley, as well as the fact, that there are two flexor tendons of which only one passes through both pulleys. Each parameter was then evaluated using a sensitivity analysis proposed by Fasham et al., 1990. Journal of Marine Research 48, 591-639 in order to determine their relative importance for the outcome of the model. The most important parameter proofed to be the positioning of the pulley with respect to the centre of rotation in the PIP joint. This observation enabled us to give the best possible placement for a pulley graft after pulley rupture.

Treatment of ingrown toenails using a new conservative method: a prospective study comparing brace treatment with Emmert's procedure.

Ingrown toenails cause incapacitation and pain for the patient and lost time from work. Many different conservative and surgical treatment methods have been described. European chiropodists and podologists have long treated ingrown toenails with orthonyxia, which consists of implantation of a small metal brace or plate onto the dorsum of the nail. To determine whether orthonyxia is an acceptable alternative to surgery, we compared the VHO-Osthold brace (VHO-Osthold-Spange GmbH, Deisenhofen, Germany), a new method of orthonyxia, with Emmert's procedure, a standard surgical method that is virtually identical to the Winograd-type procedure, in a prospective study of 41 patients (21 in the brace group and 20 in the Emmert procedure group). Pain due to treatment was significantly lower in the brace group than in the Emmert procedure group, and patients in the brace group could wear regular shoes again without appreciable pain much earlier than those in the Emmert procedure group. In the brace group, there were four recurrences, and one patient was still receiving treatment at the end of follow-up; in the Emmert procedure group, there were three recurrences. None of the patients in the brace group had to take time off from work, whereas in the Emmert procedure group, working patients were off from work for an average of 14.7 days. Brace treatment proved to be a good conservative alternative to operative procedures.
