BACKGROUND The glenohumeral joint is the most mobile joint in the human body due to the shallowness of the glenoid socket. This unique anatomy also makes it the most dislocated joint in humans. All the techniques described so far for relocation require operator control and prescription drugs. We describe a technique that is unique, easy, and patient-controlled. CASE REPORT A 29-year-old male ...

The glenohumeral joint is innately complex and comprised of both static and dynamic stabilizers. Anterior glenohumeral instability has been estimated to have an incidence of 11.2 cases per 100,000 persons and typically follows a traumatic injury. Although there are specific instances when conservative management is advocated, a majority of these patients are treated with operative stabilization...

In a subset of patients with rotator cuff tears, the glenohumeral joint has minimal degenerative changes and the rotator cuff tendon is either irreparable or very poor quality and unlikely to heal. Reverse shoulder arthroplasty (RSA) is often considered for these patients despite the lack of glenohumeral arthritis. However, due to the permanent destruction of the glenohumeral articular surfaces...

The purpose of this research is to test the experimental conditions which lead to the best determination of the glenohumeral joint rotation centre in vivo with two shoulder circumductions (30°,130° abduction) and two relative displacements (humerus with respect to scapula or clavicle). Nine subjects perform circumduction movements of small magnitude. Three functional methods were used to estima...

Synovial chondromatosis affecting the glenohumeral joint is rare. Treatment primarily consists of arthroscopic loose body removal and synovectomy. Shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. The case of an 84-year-old man with long standing synovial chondromatosis of the sh...

It is not known whether significant differences in the glenohumeral center of pressure and contact pressure exist between surface replacement arthroplasty and hemiarthroplasty compared with the native joint. Twelve fresh-frozen cadaveric shoulders were dissected free of soft tissue, and the joint capsule was removed. The scapula was potted with the glenoid parallel to the ground. A pressure-sen...

BACKGROUND The objective of this study was to investigate serial changes for histology of joint capsule and range of motion of the glenohumeral joint after immobilization in rats. We hypothesized that a rat shoulder contracture model using immobilization would be capable of producing effects on the glenohumeral joint similar to those seen in patients with frozen shoulder. METHODS Sixty-four S...
