✦ Synopsis

Computed tomography (CT) was employed to evaluate the femoral component of the prosthesis in surface-replacement total hip arthroplasty in seven patients suffering from rheumatoid arthritis. Image reconstruction using the high frequency filter resulted in an image of the cementbone interface inside the cup which allowed the detection of bone resorption. This new application of CT could prove to be a valuable complement to conventional methods in the radiological assessment of metal cup arthroplasties.
