BACKGROUND Although overhead throwing athletes may develop unique glenohumeral range of motion characteristics, to our knowledge these characteristics have not been studied longitudinally in major league pitchers. HYPOTHESIS Major league pitchers (starters and relievers) experience an increase in glenohumeral external rotation and a decrease in internal rotation and total range of motion. Gle...

The anterior-inferior glenohumeral capsule is the primary passive stabilizer to the glenohumeral joint during anterior dislocation. Physical examinations following dislocation are crucial for proper diagnosis of capsule pathology; however, they are not standardized for joint position which may lead to misdiagnoses and poor outcomes. To suggest joint positions for physical examinations where the...

Traumatic anterior glenohumeral subluxations comprise the majority of glenohumeral instability events and are endemic in young athletes. Unlike the definitive complete dislocation event, subluxation events may often be more subtle in presentation and, therefore, may be overlooked by clinicians. Glenohumeral subluxation events are associated with a high rate of labral tears as well as humeral he...

During a total shoulder replacement the glenohumeral joint is substituted by a prosthesis. The joint is a loose ball-and-socket joint, in which the humeral head is the ball and the glenoid is the socket. Most important for successful surgery is that the position of the center of rotation of the glenohumeral joint is maintained [1]. During motion, the two geometric centers of both spherical arti...

INTRODUCTION In contrast to adults, traumatic glenohumeral dislocation is a rarely observed condition among children. In some cases, success in durable reduction with conservative methods, and achieving lasting treatment, may not be possible. CASE PRESENTATION In this study, the case of a 7-year-old Turkish girl with a Salter-Harris type II fracture and glenohumeral dislocation of the proxima...

Glenohumeral arthrodesis is an end-stage salvage operation that has traditionally been performed in an open fashion. In recent years an arthroscopic approach has been described. The purpose of this report was to present an arthroscopic glenohumeral arthrodesis technique with the assistance of O-arm-based navigation. An illustrative case example is presented. This technique allows not only a min...

OBJECTIVE To determine variables among glenohumeral elevation and 3-dimensional scapular rotations that are related to shoulder function as assessed by the Disability of the Arm, Shoulder and Hand-Disability/Symptom (DASH-D/S) scale. DESIGN Prospective, cross-sectional study. PATIENTS Eighty-eight patients with shoulder pain and limited range of motion were included. METHODS Each patient ...

BACKGROUND Patients with incomplete recovery from obstetric brachial plexus injury (OBPI) usually develop secondary muscle imbalances and bone deformities at the shoulder joint. Considerable efforts have been made to characterize and correct the glenohumeral deformities, and relatively less emphasis has been placed on the more subtle ones, such as those of the coracoid process. The purpose of t...
