BACKGROUND Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. METHODS The study was a cross-sectional study evaluating patients with unstable shoulder j...

Clinical studies on primary osteoarthritis have shown better results of total shoulder arthroplasty (TSA) compared to hemiarthroplasty (HA) regarding the function, revision rate and postoperative pain relief. However, a clear recommendation for implantation of TSA or HA, depending on the glenoid type of erosion, does not exist. The aim of the study was to compare the results of TSA and HA with ...

BACKGROUND The purpose of this study was to examine biomechanical properties and the degree of radiolucency of two cemented basic glenoid designs for total shoulder arthroplasty. Our hypothesis was that a component with increased micro-motion in the laboratory at time zero would also exhibit a greater amount of radiolucency in patients at a minimum of 2 years post total shoulder arthroplasty. ...

Both clinical and biomechanical problems affecting the shoulder joint suggest that investigators should study force transmission into and out from the scapula. To analyze force transmission between the humeral head and the glenoid, one must know the position of the glenoid. Studies have analyzed the position of the scapula from the positions of three palpable points, but the position of the gle...

phy (MDCTA) and magnetic resonance arthrography (MRA) are superior to computed tomography (CT) or magnetic resonance imaging (MRI) for evaluating shoulder instability (1, 2). Previous reports have indicated that MRA is more accurate for evaluating the capsuloligamentous complex, the glenoid labrum, the intracapsular portion of the long head of the biceps tendon, and the rotator cuff than CT art...

OBJECTIVE The purpose of this article is to describe the imaging appearances of musculoskeletal injuries related to yoga. We performed an automated search in the database of a large tertiary care center and conducted a retrospective analysis of the imaging findings in 38 patients over a 9-year period. CONCLUSION The most frequently encountered musculoskeletal injuries were tendinous lesions, ...

Glenoid loosening after total shoulder arthroplasty (TSA) remains a major concern. The purpose of this study was to determine the incidence of radiolucent lines (RLLs) after TSA performed with modern glenoid bone preparation and cement techniques for keeled-back glenoid components. One hundred ten consecutive patients with osteoarthritis were included in this study. Patients had undergone prima...

OBJECTIVE To analyze whether the Bernageau radiographic view is adequate for studying the anterior glenoid rim and to determine the distance between the posterior and anterior glenoid rims. METHODS Fifty patients (31 males) with a mean age of 34 years were evaluated by positioning their arm at 160° forward flexion and body at 70° to the x-ray chassis, while positioning the x-ray tube at 30° c...

Glenoid component loosening is a commonly encountered complication of total shoulder replacements. Therefore, focus has been placed on glenoid fixation. Porous metal implants, which promote biological fixation through osteointegration, have provided an uncemented alternative to the traditional cemented implant. In this explantation study, the authors examined the bone ingrowth and ongrowth of a...
