The movement of 75 two-component hemi-arthroplasties, implanted following displaced subcapital fracture of the femoral neck, were examined radiologically in equal numbers of Hastings hips (22 mm), 22-mm Bi-articular hips and 32-mm Bi-articular hips. A classification of the movement of the two-component hemi-arthroplasty was devised. The 22-mm Bi-articular(More)
The aim of this study was to develop a reliable technique for measuring the area of a curved surface from an axial computed tomography (CT) scan and to apply this clinically in the measurement of articular cartilage surface area in acetabular fractures. The method used was a triangulation algorithm. In order to determine the accuracy of the technique, areas(More)
