Abstract:
PURPOSE: The purpose of this study was to evaluate the short term results of cementless revision total hip arthroplasty using an interlocking femoral stem. MATERIALS AND METHODS: Between November 1997 and October 1999, 73 hips were revised using a cementless, proximally-coated, long femoral stem with distal holes for interlocking screw fixation (BiCONTACT(R)). Among them, 66 patients (68 hips) were followed both clinically and radiologically for at least two years. RESULTS: The average Harris hip score was 61 (range, 33-78) preoperatively, and this improved to 85 (range, 68-95) at the last follow-up. Mild thigh pain was present in 4 patients, but was not associated with loosening. Radiologically, significant subsidence (>5 mm) of the stem was noticed in no case. A radiolucent line wider than 2 mm was present in 1 hip (zones 4 and 5), but was not progressive. At the most recent follow-up, all stems were fixed by bony ingrowth and no visible osteolysis was detected. CONCLUSION: The short term results of revision total hip arthroplasty using an interlocking femoral stem (BiCONTACT(R)) were satisfactory.
