Return to Play After Type II Superior Labral Anterior-Posterior Lesion Repairs in Athletes: A Systematic Review
Superior labral anterior-posterior (SLAP) lesions are a common cause of pain and disability in athletes. Individual studies have suggested low patient satisfaction with SLAP repairs in throwing athletes in particular and it is unclear how frequently athletes return to their previous level of competetion.
Surgical Technique Arthroscopic Posterior Glenoidplasty for Posterosuperior Glenoid Impingement in Throwing Athletes
Posterosuperior glenoid impingement (PSGI) is the repetitive impaction of the supraspinatus tendon insertion on the posterosuperior glenoid rim in abduction and external rotation. While we presume the pain is mainly caused by mechanical impingement, this explanation is controversial. If nonoperative treatment fails, arthroscopic débridement of tendinous and labral lesions has been proposed but reportedly does not allow a high rate of return to sports. In 1996, we proposed adding abrasion of the bony posterior rim, or glenoidplasty.
Osteotomy of the lesser tuberosity in shoulder arthroplasty allows bony healing of the subscapularis tendon but does not prevent fatty degeneration in its muscle. Occurrence or increase in fatty degeneration may depend on the surgical technique.
It has been suggested that limited active ROM of reverse shoulder prostheses relates to lack of strength. However, the postoperative strength has not been quantified.
Passive Range of Motion Characteristics in the Overhead Baseball Pitcher and Their Implications for Rehabilitation
Repetitive overhead throwing motion causes motion adaptations at the glenohumeral joint that cause injury, decrease performance, and affect throwing mechanics. It is essential to define the typical range of motion (ROM) exhibited at the glenohumeral joint in the overhead thrower.
The glenohumeral joint is the most mobile articulation in the body and the most commonly dislocated diarthrodial joint with peaks in the incidence of dislocation occurring during the second and sixth decades. Age at the time of the initial dislocation is inversely related to the recurrence rate. Traumatic anterior instability is often associated with intraarticular injuries. The frequency of injuries may increase with dislocation or subluxation episodes.
Glenohumeral internal rotation (GIR) and total arc of motion (TAM) decrease, whereas external rotation (GER) may increase in throwing. Although decreased GIR has been documented after throwing, its time course for recovery and the effect of pitching role have not.
Clinically evaluating the scapulothoracic joint is challenging. To identify scapular dyskinesis, clinicians typically observe scapular motion and congruence during self-directed upper extremity movements. However, it is unclear whether this method is reliable.
Surgical Treatment of Neer Group VI Proximal Humeral Fractures: Retrospective Comparison of PHILOS® and Hemiarthroplasty
Neer Group VI proximal humeral fractures often are related to persistent disability despite surgical treatment. We retrospectively compared the outcome after open reduction and internal fixation with the PHILOSplate or primary hemiarthroplasty in patients with Neer Group VI fractures focusing on complications, shoulder function, health-related quality of life (SF-36), and potential risk factors for complications.
The cause of shoulder pain and dysfunction in the overhead athlete can be variable. Several studies illustrate the wide variety of lesions seen at the time of arthroscopy in overhead athletes who require surgery but it is unclear whether these differ by sport.
