BACKGROUND Rheumatoid arthritis affecting the shoulder is typically associated with rotator cuff compromise and can also result in severe glenoid erosion. Since reverse shoulder arthroplasty is capable of addressing both rotator cuff disorders and glenoid bone deficiencies, our aim was to evaluate the outcome of reverse shoulder arthroplasty in patients(More)
BACKGROUND Recent studies have reported the theoretic amount of coracoid graft available for harvesting with the Latarjet procedure. Our aim was to investigate the actual dimensions of coracoid grafts harvested using a standardized technique. We also hoped to confirm previous recommendations regarding placement of the inferior glenoid drill hole to avoid(More)
PURPOSE We assessed the clinical and radiologic results of a cemented all-polyethylene convex-back keeled glenoid component used with a third-generation prosthesis. METHODS Between 1996 and 2003, in 4 European centers, 333 shoulder arthroplasties were performed for primary osteoarthritis by use of a cemented all-polyethylene convex-back keeled glenoid(More)
Osteoarthritis is a disease of multifactorial aetiology characterised by progressive breakdown of articular cartilage. In the early stages of the disease, changes become apparent in the superficial zone of articular cartilage, including fibrillation and fissuring. Normally, a monolayer of lubricating molecules is adsorbed on the surface of cartilage and(More)
Improved staging of cartilage degeneration is required, particularly during early stages when minimal surface damage is visible arthroscopically. Degradation of articular cartilage extracellular matrix, resulting from degenerative changes associated with osteoarthritis, can influence its functional properties. Cartilage mechanical properties therefore may(More)
OBJECTIVES Published scoring methods for quantifying synovitis focus on acute inflammatory parameters, and are unsuitable as outcome measures in experimental surgical models of osteoarthritis (OA). The aim of the present study was to define a modified histopathological scoring system for ovine synovium more suited to the chronic pathology induced by ovine(More)
Recurrent anterior shoulder instability is common in contact athletes and the high-energy injuries seen in this group make them more prone to bone loss. Athletes with recurrent instability and associated bone loss have high failure rates when treated with a soft tissue reconstruction procedure. Therefore it is preferred to manage recurrent instability in(More)
Controversy surrounds the optimal technique for fixation of displaced fractures, although locked intramedullary nailing is emerging as a preferred technique in managing displaced proximal humerus fractures in appropriately selected patients. This technique provides stable fracture fixation allowing early postoperative mobilization critical in ensuring a(More)
