REVIEW
Joseph N Liu, Grant H Garcia, Anirudh K Gowd, Brandon C Cabarcas, Michael D Charles, Anthony A Romeo, Nikhil N Verma
PURPOSE OF REVIEW: To review the etiology, classification, presentation, evaluation, treatment strategy, and outcomes in overhead athletes with partial thickness rotator cuff tears. RECENT FINDINGS: Despite advances in surgical repair techniques, return to play following surgical repair of partial rotator cuff tears remains modest at best. Overhead athletes may be particularly prone to rotator cuff pathology due to the supraphysiological strains within the tendon during the throwing motion, as well as mechanical stress with contact between the undersurface of the rotator cuff and the glenoid...

Study Design Cross-sectional study. Background The drop vertical jump task is commonly used in anterior cruciate ligament injury risk screening; however, the predictive validity is limited. Part of the limited predictive validity may be because the drop vertical jump task does not impose cognitive demands that reflect sports participation. Objectives To investigate the influence of additional cognitive demands on lower extremity mechanics during execution of the drop vertical jump task. Methods Twenty uninjured females (ages 18-25 years old) were required to perform the standard drop vertical jump task, as well as drop vertical jumps which included additional cognitive demands...

Medial-sided elbow pain is becoming more common among pediatric overhead sport athletes. One potential cause of this is a partial or complete tear of the ulnar collateral ligament (UCL). Because the growth plate remains open in many of these athletes, the most common injury experienced is an avulsion at the medial epicondyle. However, although rare, there is a potential to tear the UCL, with the most common tears occurring at the anterior bundle. However, tears to the posterior bundle are quite rare in pediatric patients...

EDITORIAL
Frank A Cordasco
I believe that arthroscopic repair is the treatment of choice for patients with partial thickness rotator cuff tears when nonoperative methods have been exhausted. Excluding overhead athletes and patients in whom long head biceps tendon pathology is the primary concern, I do not believe that a significant role exists for debridement with or without acromioplasty in the majority of patients with partial thickness tears. Regarding the repair technique, I prefer in situ repair for bursal-sided tears because the superior capsule is intact and completion of the tear with repair for articular-sided tears...

Posterior impingement pain in baseball players is typically due to a fractured olecranon osteophyte. Computed tomographic (CT) scanning is the imaging of choice when evaluating posterior or posteromedial elbow pain in athletes who have subjected the elbow to excessive stresses such as occur in overhead throwing and weightlifting. Sometimes the fracture fragment can be so small that it might not be detected on plain radiographs, magnetic resonance imaging, or even at the time of arthroscopy. Symptomatic fractured olecranon osteophytes can be diagnosed clinically with the extension impingement test or arm bar test...

Osteochondritis dissecans (OCD) of the humeral capitellum is a critical elbow injury in adolescent overhead throwing athletes. However, its etiology remains unknown. Medical examinations using ultrasonography found that the prevalence of capitellar OCD among adolescent baseball players was approximately from 1% to 3%. A plain anteroposterior radiograph with the elbow in 45° of flexion is essential for the diagnosis of an OCD lesion. The stability of OCD lesions is evaluated on plain radiographs, computed tomography, and magnetic resonance imaging (MRI)...

We analyzed three-dimensional (3D) humeral deformity (valgus-varus, flexion-extension, and rotational deformation) after little leaguer's shoulder using 3D computed tomography in a 15-year-old male baseball player. Humeral retroversion was increased by 27.1° on the dominant side compared with the nondominant side. Compared with the nondominant shaft, the dominant humeral shaft was deformed in the varus direction (9.4°), resulting in a decreased neck-shaft angle (dominant side, 127.5°; nondominant side, 135...

BACKGROUND: Handball is a physical contact sport that includes frequent overhead throwing, and this combination leads to a high rate of shoulder injuries. Several factors have been associated with shoulder injuries in overhead athletes, but strong scientific evidence is lacking for most suggested risk factors. We therefore designed the Karolinska Handball Study (KHAST) with the aim to identify risk factors for shoulder injuries in adolescent male and female elite handball players studying at handball-profiled secondary schools in Sweden...

Elbow or shoulder injuries are common in overhead sports. Because energy derived from the lower extremity passes through the trunk to the upper extremity in overhead motion, a break in such a kinetic chain could lead to arm injuries. However, there is only limited information about the role of the trunk and lower extremity support in preventing elbow or shoulder injuries. This study aimed to explore the association of trunk and lower extremity pain with elbow/shoulder pain among young overhead athletes. We conducted a cross-sectional study using self-reported questionnaires mailed to young athletes belonging to the Miyagi Amateur Sports Association...

Background: The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the symptoms. The aim of this general article is to summarize the main examination manoeuvres that could be included in an overall approach to a patient with a suspicion of instability...

Creatine supplementation reduces the impact of muscle fatigue on post-activation potentiation (PAP) of the lower body, but its effects on the upper body remain unknown. This study examined the effects of creatine supplementation on muscle strength, explosive power, and optimal individual PAP time of the upper body during a set of complex training bouts in canoeists. Seventeen male high school canoeists performed a bench row for one repetition at maximum strength and conducted complex training bouts to determine the optimal individual timing of PAP and distance of overhead medicine ball throw before and after the supplementation...

Quadrilateral space syndrome (QSS) is a rare orthopedic condition caused by compression, entrapment, or injury to the axillary nerve or posterior humeral circumflex artery as they arise from the quadrilateral space. QSS can present with point tenderness over the quadrilateral space and weakness and paresthesia in the axillary nerve distribution. It is commonly associated with repetitive overhead activities and is seen in athletes engaging in such activities. Here we report a case of QSS in a 42-year-old male weight lifter who presented with pain and soreness in the posterior aspect of his right shoulder radiating around his arm as well as slight weakness of his right shoulder of a few weeks duration...

The Ballistic Six exercise program includes commonly used upper-body exercises, and the program is recommended for overhead throwing athletes. The purpose of the current study was to investigate the effects of a 12-week the Ballistic Six upper-extremity plyometric training program on upper-body explosive power, endurance, and reaction time in pediatric overhead athletes. Twenty-eight female pediatric volleyball players participated in the study. The participants were randomly divided into 2 study groups: an intervention group (upper-extremity plyometric training in addition to the volleyball training; n = 14) and a control group (the volleyball training only; n = 14)...
