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. ...

Aim: The aim of this study was to determine the notch and shape variations glenoid cavity (GC), emphasize its clinical importance, compare it with previous studies. Material Methods: This performed 157 (78 right sides, 79 left sides) adult Anatolian dry scapulae. GCs were typed as oval, pear, inverted comma shaped noted number GC notch. Results: most common found pear 63 (80.8%) at side, 49 (62...

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...

Aim: The aim of this study is to determine the average morphometric parameters scapula accurate and successful analyzes in clinic. Material Methods: A total 24 dry bone were included study. Parameters determined on scapula; superio-inferior glenoid diameter (SIGD), anterio-posterior 1 (APG1), 2 (APG2), 3 (APG3), width (SW), length (SL), basis-spina distance (BS), spina (SSW), acromiocoracoid (A...

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...

CONTEXT Osseous injury to the glenoid is increasingly being recognized as one of the most important aspects in the successful management of recurrent shoulder instability. Proper early recognition of glenoid bone injury in the setting of recurrent instability will lead to successful nonoperative and operative decision making, particularly in the athletic patient. EVIDENCE ACQUISITION We condu...

BACKGROUND A Hill Sachs lesion is a posterior-superior bony defect of the humeral head caused by a compression of the hard glenoid rim against the soft cancellous bone in the context of an anterior instability episode. The presence of these humeral defects increases with the number of dislocations and larger lesions are associated with a greater chance of development of recurrent instability an...
