Osteolysis, which is considered to be a major source of morbidity following total hip joint replacement, has been notoriously difficult to measure accurately, particularly in the acetabular area. In order to study periacetabular osteolysis, specialized software for computerized tomography (CT) scan image analysis has been developed. This software (3D-CT)(More)
Twenty-three cadaver forearm specimens were mounted on a Plexiglas acrylic plastic base for study of the trapeziometacarpal joint. Extrinsic and intrinsic motors were loaded to simulate lateral pinch, and pressure-sensitive film was used to record joint contact patterns in various functional positions. The palmar compartment of the trapeziometacarpal joint(More)

Distraction is usually performed by use of a standard traction table and foot plate, with the patient in either the supine or lateral position. Between 1996 and 2005 at our institution, we have used an inexpensive,(More)
