Medial Proximal Tibia Physeal Overuse Injury of an Athlete.

Overuse injuries are well described for both upper and lower extremities among skeletally immature athletes. To our knowledge, there is no description in the literature of an overuse injury affecting the medial tibial physis that is different from the typical Osgood-Schlatter disease or tibial tubercle apophysitis. In this article we present a 13-year-old athlete with medial proximal tibial widening or epiphysiolysis from overuse playing soccer. We need to be aware that with increased early sports specialization we may see injuries we have not seen before. [Orthopedics. 2022;46(6):e345-e347.].

Surgery for trapeziometacarpal osteoarthritis in relation to cumulative occupational hand force requirements: a Danish nationwide cohort study.

OBJECTIVES: To evaluate if higher cumulative occupational hand force requirements are associated with higher risks of surgery for trapeziometacarpal osteoarthritis and with surgery earlier in life. METHODS: The study was based on Danish national registers. Among all persons born in Denmark 1931 to 1990, we included those who had been employed for at least 5 years since 1991 by the end of 2000, or later when this employment criterion was reached, up until the end of 2016. Cumulative exposure estimates for 10-year time windows (force-years) were assessed by combining individual year-by-year information on occupational codes with an expert based hand-arm job exposure matrix. First-time events of surgery for trapeziometacarpal osteoarthritis 2001 to 2017 constituted the outcome. Surgery rates were analysed by a logistic regression technique equivalent to discrete survival analysis using a 1-year lag. We also calculated rate advancement periods. RESULTS: A total of 2 860 448 persons contributed with around 48 million person-years of follow-up, during which 3977 cases appeared (821 among men and 3156 among women). Compared with <5 force-years, the adjusted OR (ORadj) for ≥5 to <10 force-years was 1.39 (95% CI 1.14 to 1.68) and for ≥10 to 30 force-years 1.47 (95% CI 1.26 to 1.71) among men and 1.64 (95% CI 1.50 to 1.78) and 1.29 (95% CI 1.16 to 1.43) among women. The sex combined ORadj were 1.59 (95% CI 1.47 to 1.72) and 1.36 (95% CI 1.25 to 1.48). Among the exposed, surgery was advanced by 3 to 7 years. CONCLUSION: Medium/high cumulative hand force requirements were associated with elevated hazard rates of surgery for trapeziometacarpal osteoarthritis and advanced the time of surgery by several years.

Utility of Percutaneous Ultrasonic Tenotomy for Tendinopathies: A Systematic Review.

CONTEXT: Chronic tendinopathy is a challenging problem that can lead to significant disability and limitation in not only athletics but also activities of daily living. While there are many treatment techniques described for this overuse injury, no single modality has been proven superior to all others. With recent advances in medical technology, percutaneous ultrasonic tenotomy (PUT) for tendinosis has gained traction with promising results. OBJECTIVE: To examine the data published on PUT for treatment of tendinopathy, analyze the outcomes of the procedure, including duration of pain relief and patient-reported outcomes, and assess the rate of complications associated with the procedure. DATA SOURCES: PubMed, MEDLINE, EMBASE, and Google Scholar. STUDY SELECTION: The following combination of keywords was entered into the electronic search engines: ultrasonic tenotomy, ultrasound tenotomy, Tenex, and ultrasonic percutaneous tenotomy. The search results were screened for studies relevant to the topic. Only English-language studies were considered for inclusion. Studies consisting of level 4 evidence or higher and those involving human participants were included for more detailed evaluation. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Articles meeting the inclusion criteria were sorted and reviewed. Type of tendinopathy studied, outcome measures, and complications were recorded. Both quantitative and qualitative analyses were performed on the data collected. RESULTS: There were a total of 7 studies that met the inclusion criteria and quality measures-5 studies involving the treatment of elbow tendinopathy and 1 study each involving the management of Achilles tendinopathy and plantar fasciitis. PUT resulted in decreased pain/disability scores and improved functional outcome scores for chronic elbow tendinopathy and plantar fasciitis. Results for Achilles tendinopathy showed modest improvement in the short term, but long-term data are lacking. CONCLUSION: PUT is a minimally invasive treatment technique that can be considered in patients with tendinopathy refractory to conservative treatment measures. Further higher quality studies are necessary to accurately assess the comparative effectiveness of this treatment modality.

Olecranon Stress Fracture.

Olecranon stress fractures are a rare upper extremity fracture that primarily affects throwing athletes. The incidence of olecranon stress fractures are increasing owing to the number of patients playing and the volume of engagement in competitive sports, especially in the pediatric population. However, olecranon stress fractures can present a challenge from a management and a rehabilitation perspective owing to their vague presentation, thereby affecting how these patients are diagnosed and managed. Therefore, it is imperative to further evaluate the disease process, diagnosis, and treatment of this condition to best manage our patients.

Rehabilitation of Elbow Injuries: Nonoperative and Operative.

Athletes are subject to traumatic and repetitive stress injuries at the elbow joint as a result of high levels of forces imparted across the elbow. Injuries can be acute to the point of tissue failure, or chronic as a result of repetitive overuse. Complete restoration of elbow function must be achieved to allow the athlete to return to their prior level of function. Systematic and progressive rehabilitation programs can help avoid overstressing healing tissues. Treatment programs are designed to restore full motion, muscular strength, endurance, and neuromuscular control. Multiphased rehabilitation programs are designed to restore function in the athlete's elbow.

Comprehensive Review of Rock Climbing Injuries.

Increasing numbers of people are participating in the sport of rock climbing, and its growth is expected to continue with the sport's Olympic debut in 2020. Extreme loading of the upper extremities, contorted positioning of the lower extremities, rockfall, and falling from height create an elevated and diverse injury potential that is affected by experience level and quantity of participation. Injuries vary from acute traumatic injuries to chronic overuse injuries. Unique sport-specific injuries to the flexor tendon pulley system exist, but the remaining musculoskeletal system is not exempt from injury. Orthopaedic evaluation and surgery is frequently required. Understanding the sport of rock climbing and its injury patterns, treatments, and prevention is necessary to diagnose, manage, and counsel the rock-climbing athlete.

An Unusual Case of a Fibular Sesamoid Phalangeal Ligament Tear Caused By Chronic Trauma.

Injuries involving the first metatarsophalangeal joint and its associated structures are common, especially in athletes. However, injuries to the hallucal sesamoid complex constituted only 3% of all podiatric sports medicine injuries reported by Agosta. This case study reports a female ballet dancer with an isolated fibular sesamoid retraction injury that presented with a history of chronic microtrauma secondary to overuse. When consulting epidemiologic studies of forefoot injuries involving the hallucal sesamoid complex, we were unable to find a single instance of an isolated retraction of the fibular sesamoid resulting from chronic use, demonstrating the unusual nature of this case.

Surgery in Tendinopathies.

Tendinopathies are challenging. The term "tendinopathy" refers to clinical condition characterized by pain, swelling, and functional limitations of tendons and nearby structures. Tendinopathies give rise to significant morbidity, and, at present, only limited scientifically proven management modalities exist. Achilles and patellar tendons are among the most vulnerable tendons, and among the most frequent lower extremity overuse injuries. Achilles and patellar tendinopathies can be managed conservatively and surgically. Several surgical procedures have been described for both conditions, and, if performed well, they lead to a relatively higher rate of success with low complication.

Iliotibial band friction syndrome: An original technique of digastric release of the iliotibial band from Gerdy's tubercle.

The various surgical techniques to treat iliotibial band friction syndrome consist in releasing the iliotibial band by means of plasties that partially interrupt its continuity or by release of the deep aspect. We describe an original technique of digastric distal iliotibial band release from Gerdy's tubercle. Via a 2 cm approach above Gerdy's tubercle, the iliotibial band is incised longitudinally and partially released from the tubercle. Fourteen knees underwent the procedure. With a mean 27±20.6 months' follow-up (range, 12-69 months), return to sport at previous level was possible at a mean 4±2.18 months (range, 1-8 months). Eight patients were very satisfied, 3 satisfied and 2 (15%) dissatisfied. Respect of continuity is a key-point in this technique to control internal rotation of the knee.

Isolated Compression of the Ulnar Nerve Motor Branch: A Case Series With 3 Unique Etiologies.

BACKGROUND: Although ulnar neuropathies are commonly encountered, isolated involvement of the motor branch is exceedingly rare. Previous reports of this entity describe compression as the deep motor branch passes through the piso-hamate hiatus and the adductor pollicis hiatus. This case series described 3 cases of motor branch compression due to unique etiologies which resolved after surgery. METHODS: A retrospective chart review identified patients with compression of the ulnar nerve motor branch. From these patients, 3 were selected with a unique etiology for compression. Patient demographics, objective and subjective findings, and pathology identified during surgery were recorded and analyzed. RESULTS: Eight patients had compression of the ulnar nerve motor branch and 3 unique etiologies were selected; an intraneural ganglion, a constricting leash of vessels, and a series of compressing fibrous bands. All required surgery, and each patient had full resolution of symptoms by 1 year postoperatively. DISCUSSION: Patients presenting with complaints of weakness with a positive Froment and Egawa signs but a negative Wartenberg sign and no sensory complaints can be a diagnostic dilemma. Compression of the ulnar nerve motor branch must be considered, and here we present 3 unique cases. Activity modification in those presenting early may be curative, although many ultimately require surgery. In the cases presented here, all patients experienced full resolution of their symptoms by 1 year after surgery.

Surgery for subacromial impingement syndrome in relation to intensities of occupational mechanical exposures across 10-year exposure time windows.

OBJECTIVES: We aimed to identify intensities of occupational mechanical exposures (force, arm elevation and repetition) that do not entail an increased risk of surgery for subacromial impingement syndrome (SIS) even after prolonged durations of exposure. Additionally, we wanted to evaluate if exposure to hand-arm vibration (HAV) is an independent risk factor. METHODS: We used data from a register-based cohort study of the entire Danish working population (n=2 374 403). During follow-up (2003-2008), 14 118 first-time events of surgery for SIS occurred. For each person, we linked register-based occupational codes (1993-2007) to a general population job exposure matrix to obtain year-by-year exposure intensities on measurement scales for force, upper arm elevation >90° and repetition and expert rated intensities of exposure to HAV. For 10-year exposure time windows, we calculated the duration of exposure at specific intensities above minimal (low, medium and high). We used a logistic regression technique equivalent to discrete survival analysis adjusting for cumulative effects of other mechanical exposures. RESULTS: We found indications of safe exposure intensities for repetition (median angular velocity <45°/s), while force exertion ≥10% of maximal voluntary electrical activity and upper arm elevation >90° >2 min/day implied an increased risk reaching ORs of 1.7 and 1.5 after 10 years at low intensities. No associations were found for HAV. CONCLUSIONS: We found indications of safe exposure intensities for repetition. Any intensities of force and upper arm elevation >90° above minimal implied an increased risk across 10-year exposure time windows. No independent associations were found for HAV.

Arthroscopic treatment successfully treats posterior elbow impingement in an athletic population.

PURPOSE: Posterior elbow impingement can cause disabling pain and limited motion during activities involving elbow extension. Less understood is whether arthroscopic treatment, compared to open surgery, can result in effective management of pain, loss of range of motion, and return athletes to previous levels of activity. This study determined whether arthroscopic debridement is a safe and effective treatment for posterior elbow impingement and whether it enables athletes to return to a previous level of function. METHODS: A retrospective review of 36 consecutive patients that underwent arthroscopic debridement of the posterior elbow was performed. There were 34 male and 2 female patients, with a median age of 32 years (17-54 years). There were 7 professional athletes, 6 college athletes, and 23 high school or recreational athletes. All patients had a positive posterior impingement test for posterior pain with extension and limitations of activity. Arthroscopic debridement and additional surgical procedures were performed, and patients underwent follow-up visits at a median 51 months (range 14-81). RESULTS: Significant improvements were seen in pain, motion, and function. No neurovascular complications were seen related to the arthroscopic debridement. The mean Andrews and Timmerman elbow score improved from 159 ± 27 to 193 ± 11 (p < 0.01). Thirty-five of thirty-six (97%) patients returned to their previous level of activity, including all professional athletes. CONCLUSIONS: Arthroscopic management of posterior elbow impingement is safe and effective and can return patients, including professional athletes, to high-level athletic activity. Athletes with symptomatic posterior elbow impingement can be successfully and safely treated with arthroscopic debridement and typically will return to preinjury levels of activity. LEVEL OF EVIDENCE: IV.

Unusual case of hypotenar Hammer Syndrome and carpal tunnel syndrome association.

BACKGROUND AND AIM OF THE WORK: Hypothenar Hammer Syndrome is a relatively rare disease process caused by repetitive stress or injury to the hypothenar eminence leading to chronic injury to the ulnar artery. Our study reports an unusual case. METHODS: A 57 years old Plumber presented in April 2016 with a history of constant pain and recurrent paresthesia involving the fingers of the right hand for several months, over the previous 1 year, his hand had become more intolerant of exposure to cold temperatures. Angio-RNM and electromyography were performed and showed a severe double compression of ulnar and median nerve and an ulnar artery deformity without thrombosis. Surgery was performed under sedation and axillary anesthesia. RESULTS: After surgery patient' symptoms immediately improved, and within a few months, his hand had normalized. CONCLUSION: Hypothenar Hammer Syndrome is a rare disease process which manifests in certain occupations and activities that put undue stress on the hypothenar area. Furthermore, the carpal tunnel syndrome, a pressure damage of the median nerve, caused by repetitive manual tasks with flexion and extension of wrist has been added as well as hypothenar hammer syndrome which are vascular damages of hand caused by shock-type application of force.

Rupture of the Extensor Hallucis Longus Muscle Secondary to Repetitive Overuse in a Taekwondo AthleteA Case Report.

Closed rupture of the extensor hallucis longus (EHL) tendon is rare, with most cases caused by either direct penetrating trauma or predisposing factors such as corticosteroid injection and iatrogenic trauma incidences. Almost all of the previous case reports have reported on rupture of the EHL tendon rather than the EHL muscle. In this report, we highlight an unusual clinical presentation of a rupture of the EHL muscle and discuss its predisposing factors. This patient was a taekwondo athlete with EHL muscle rupture secondary to repetitive overuse without any underlying systemic or local predisposing factors or direct trauma. Fifteen months after successful surgical treatment, he became fully functional again as an elite taekwondo athlete.

Endoscopic Fascia Release for Forearm Chronic Exertional Compartment Syndrome: Case Report and Surgical Technique.

BACKGROUND: Chronic exertional compartment syndrome (CECS) of the forearm is traditionally treated with open compartment release requiring large incisions that can result in less than optimal esthetic results. The purpose of this study is to describe a case report of 2 professional motocross patients with forearm CECS treated endoscopically using a minimally invasive technique. METHODS: Two professional motocross racers presented with a history of chronic proximal volar forearm pain when motocross riding. Other symptoms included paresthesia and weakness, which, at times, led to an inability to continue riding. Both failed conservative management. Compartment pressure measurements were performed before and after provocative exercises to confirm diagnosis of CECS. Release of both the volar and dorsal compartments was performed endoscopically through a single incision. RESULTS: Symptoms resolved after surgery. The first patient resumed riding at 1 week, competing at 3 weeks, and continues to ride competitively without symptoms at 3 years postoperative. The second patient began riding at 1 week and won second place in the National Supercross finals 5 weeks after simultaneous bilateral release. CONCLUSIONS: This technique is simple and effective. The cannula used protects the superficial nerves while allowing release through a small, cosmetically pleasing incision.

Failure of Bone Marrow Stimulation Techniques.

Marrow stimulation techniques, including microfracture, are among the most commonly performed cartilage restoration procedures for symptomatic chondral defects of the knee. For the vast majority of patients, marrow stimulation results in reduced pain and improved function, providing overall satisfactory outcomes. In some cases, however, marrow stimulation fails, resulting in symptom recurrence and often, the need for repeat surgery. This review will describe the indications and outcomes of microfracture as a primary surgical treatment for focal chondral defects of the knee, identify patient and procedure-specific factors associated with poor clinical outcomes, and will discuss treatment options and their respective outcomes for patients with a failed prior microfracture surgery.

Fast Early Recovery After Transabdominal Preperitoneal Repair in Athletes with Sportsman's Groin: A Prospective Clinical Cohort Study.

BACKGROUND: Current literature on chronic groin pain suggests that laparoscopic mesh repair on athletes enables a faster recovery and subsequent return to unrestricted athletic activities. The aim of this study was to evaluate the role of transabdominal preperitoneal (TAPP) mesh repair in athletes resistant to conservative therapy. METHODS: A multidisciplinary approach with tailored physiotherapy. Thirty-nine professional athletes with chronic groin pain were referred to surgery at a single clinic. A full assessment was carried out on each, including medical history, physical examination, dynamic ultrasound, and pelvic magnetic resonance imaging. TAPP repair was performed using a polypropylene mesh and fibrin glue fixation on 30 athletes who had exhibited typical symptoms, shown resistance to conservative therapy, not benefited from accompanying physiotherapy, and had ceased training in the 3 to 6 months prior. The outcome measures were early postoperative recovery of 6 weeks and full resumption of athletic activities. RESULTS: Mean duration of symptoms from onset to surgical repair was 7 months. Conservative treatment had improved symptoms temporarily or to some extent in 7 athletes, while 2 ceased competing altogether. Twenty-three athletes exhibited unilateral and 16 bilateral groin pain. Laparoscopy confirmed posterior wall deficiency in 24 and true inguinal hernia in 6 athletes. Mild scrotal hematoma occurred in 2 athletes postoperatively; all were discharged within 24 hours of surgery. Twenty-one (70%) returned to sports activities after 6 weeks of convalescence. Persistent mild pain was experienced by 5 athletes postoperatively for up to 1 year, yet did not interfere with normal daily activity. Twenty-five participants (85%) reported full satisfaction with the procedure 1 year after treatment; all returned to the same or even higher level of athletic performance. CONCLUSION: The study confirms that the endoscopic placement of retropubic mesh is an efficient, safe, and minimally invasive treatment that enables fast early recovery.

Medial Elbow Injuries in the Throwing Athlete.

Medial elbow injuries in the throwing athlete are common and increasing in frequency. They occur due to repetitive supraphysiologic forces acting on the elbow during the overhead throw. Overuse and inadequate rest are salient risk factors for injury. Most athletes improve substantially with rest and nonoperative treatment, although some athletes may require surgical intervention to return to play. Because of advances in conservative and surgical treatments, outcomes after medial elbow injury have improved over time. Currently, most athletes are able to return to a high level of play after ulnar collateral ligament reconstruction and experience a low rate of complications.
