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.
The natural history of spontaneous idiopathic frozen shoulder is controversial. Many studies claim that complete resolution is not inevitable. Based on the 40-year clinical experience of the senior author, we believed most patients with idiopathic frozen shoulder might have a higher rate of resolution than earlier thought.
Stress lesions of the upper extremity are relatively uncommon, and physeal stress lesions of the clavicle are rare. We present a case of bilateral physeal stress-related lesions of the proximal clavicular growth plate near the sternoclavicular joint in an adolescent male gymnast.
Goniometers can be used to assess shoulder ROM with reasonable accuracy, but not internal rotation. Vertebral level, as determined by the hand-behind-the-back method, is used frequently but its reproducibility is questionable. We therefore devised a new measuring tape-based method for determining vertebral level.
There is a lack of consensus regarding optimal surgical management of displaced and unstable three-part proximal humeral fractures.
Is Reverse Shoulder Arthroplasty Appropriate for the Treatment of Fractures in the Older Patient?: Early Observations
The treatment of comminuted proximal humerus fractures in older patients is challenging. Variable values of functional outcomes scores, ROMs, patient satisfaction, and bony healing have been reported with conventional techniques, including open reduction and internal fixation, percutaneous pinning, and hemiarthroplasty. Another alternative is reverse total shoulder arthroplasty, although it is unclear whether this provides better ROM or function.
