The amount of articular curvature mismatch providing optimal performance in total shoulder arthroplasty (TSA) is unknown. The objectives of this study were to quantify glenohumeral joint mechanics before and after TSA and to compare the performance of 3 glenoid components: (1) nonconforming, (2) conforming, and (3) a novel design featuring a conforming center extending into a nonconforming peri...

BACKGROUND AND PURPOSE It is difficult to evaluate glenoid component periprosthetic radiolucencies in total shoulder arthroplasties (TSAs) using plain radiographs. This study was performed to evaluate whether computed tomography (CT) using a specific patient position in the CT scanner provides a better method for assessing radiolucencies in TSA. METHODS Following TSA, 11 patients were CT scan...

We present a case of an intra-articular osteoid osteoma in the knee that was mistaken for a painful fabella syndrome after unsuccessful knee arthroscopy for the treatment of postero-lateral knee pain. In this case both the initial clinical presentation and the imaging proved to be deceiving. The diagnosis of intra-articular osteoid osteoma was considered only once typical clinical features appe...

INTRODUCTION Knee osteoarthritis is characterized by inflammation in the intra-articular space or synovial membrane, breakdown of articular cartilage, and sclerosis of the subchondral bone. Intra-articular injections of Sodium hyaluronate which have viscoelastic and protective effect on articular cartilage and restores normal articular homeostasis. The efficacy of these injections is diminished...

BackgroundThere are various modifications of the Bankart repair, and postoperative changes to glenoid morphology after repair reported. Among procedures performed, a decrease in lateral diameter might be related surgery that involves removal articular cartilage labrum–anterior inferior glenohumeral ligament complex on surface. This is contrast cases without significant bony lesions not edge gle...

The calcaneus is the most commonly fractured tarsal bone. Displaced intraarticular calcaneal fractures are usually caused by a fall from height with one or both heels directly hitting the ground. Displaced intra-articular calcaneal fractures are complex and highly disabling injuries. There is ongoing debate regarding the optimal treatment for each type of displaced intra-articular calcaneal fra...
