An anterior glenohumeral dislocation is a serious condition which can lead to soft tissue damage and substantial defects of the humeral head and glenoid. Disturbance of shoulder joint congruency and soft tissue balancing can lead to poor function and severe impairment in these patients [1]. Little is known about the results of shoulder arthroplasty for the treatment of fixed glenohumeral disloc...

Rotator cuff arthropathy is often associated with disabling pain and shoulder dysfunction. When non operative treatment options have failed, reverse shoulder replacement is usually indicated. Alternative treatment options may be prudent in younger patients, those with multiple co morbidities compromising surgical options, or those unable to comply with postoperative rehabilitation. There is lit...

Rotator cuff injury (RCI) is a major musculoskeletal disorder in the adult population where inflammation and pain are major contributing factors. Coincidence of other clinical conditions like glenohumeral arthritis aggravates inflammation and delays the healing response. The mechanism and signaling factors underlying the sustenance of inflammation in the rotator cuff joint are largely unknown. ...

BACKGROUND There remains controversy on the role of the deltoid on glenohumeral translations during basic and pitching motions. We thus studied the passive effect of the deltoid on the deltoid glenohumeral joint center (GHJC). METHODS Six shoulders were tested using an automated mechanical system. A baseline motion pattern of the intact specimen was contrasted with glenohumeral translation af...

Osteochondritis dissecans (OCD) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. In this study, we report an asymptomatic case of humeral head OCD, which was detected incidentally following a trauma. X-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. However, the...

Milwaukee shoulder syndrome or rapid destructive arthropathy of the shoulder is a rare form of arthropathy that mainly affects elderly women. It is characterized by a rapid destruction of the glenohumeral joint and the rotator cuff and by an important noninflammatory joint effusion containing hydroxyapatite crystals. Radiography plays an important role in the evaluation of patients with articul...

BACKGROUND Shoulder injuries account for up to 17% of all golf related musculoskeletal injuries. One cause may be the repetitive stresses applied to the lead shoulder during the backswing and follow-through phases, which may contribute to the frequency of these injuries. The "elite" golfer may be pre-disposed to developing a shoulder injury based upon the reported adaptations to the glenohumera...

The purpose of this study was to characterize the role of the capsule in the interval between the supraspinatus and subscapularis tendons with respect to glenohumeral motion, translation, and stability. We used a six-degrees-of-freedom position-sensor and a six-degrees-of-freedom force and torque-transducer to determine the glenohumoral rotations and translations that resulted from applied load...
