The glenohumeral joint is a spherical articulation with a remarkable range of motion in several planes and decreased stability. The maintenance of joint stability is influenced by the functioning of specific muscle groups in the shoulder region, a complex system of ligaments reinforcing the joint capsule, and the labrum which augments the glenoid fossa. Lesions of the aforementioned structures ...

The glenoid version is an important factor in the etiology of anterior dislocation of the shoulder and the planning of shoulder surgery. Few reports compare the magnetic resonance imaging (MRI) measurements of the glenoid version with those of computed tomography (CT). This study aimed to show that it is possible to use MRI instead of CT, which is accepted as the gold standard today for the eva...

BACKGROUND As resource allocations in health care are being increasingly guided by cost containment issues, surgical professionals must consider the costs associated with various procedures. The present study identifies the financial costs attributed to the two principal treatment options available for zygoma fractures: the Gillie's method and open reduction and internal fixation (ORIF). METH...

BACKGROUND The integrity of the glenoid defines the surgical treatment in anterior shoulder instabilities. The reliability of plain radiographs to detect anterior glenoid rim deficiencies was determined. MATERIALS AND METHODS The anterior sclerotic glenoid line (SGL) was assessed on anteroposterior radiographs of 86 shoulders (34 anterior instabilities, 15 posterior instabilities, 37 stable) ...

Glenoid dysplasia is an uncommon developmental abnormality of the scapula that is frequently overlooked. We report a case of severe glenoid dysplasia in a 55 year old man and demonstrate its radiographic, direct MR arthrographic and arthroscopic appearances.

BACKGROUND Reverse total shoulder arthroplasty has become a widely accepted surgical procedure in Japan since the time when the implants were approved for use in 2014. There is a doubt, however, as to whether the implants designed for Western people are suitable for Japanese people, particularly for females of relatively small stature. The purpose of this study was to investigate the glenoid di...
