ABSTRACT
PURPOSE:
The purpose of this study was to report the long-term clinical and radiological results of reverse hybrid total hip arthroplasty. MATERIALS ANDMETHODS:
Between Oct. 1984 and Dec. 1987, reverse hybrid total hip replacements were performed using cemented all-polyethylene acetabular cup and porous coated tri-lock femoral stem. 26 cases in 25 patients were followed up more than 10 years.RESULTS:
The average Harris hip score was 50 points preoperatively, 88 points at last follow-up. Two patients (7.7%) complained thigh pain at POD 1 years and 4 patients (15.4%) complained inguinal pain at last follow-up. On the radiologic findings, endosteal bone formation were observed with bone apposition mainly on the Gruen zone 2 and 6. Osteolysis developed in the proximal portion of the femoral stem, respectively. Definite loosening were found in 9 cases (34.6%) in the acetabulum and none in the femur. The mean rate of linear wear of polyethylene was 0.14 mm/year and the mean rate of volumetric wear was 108.75 mm3/year.CONCLUSION:
The high incidence of acetabular loosening, presumably because of poor bone stock and great volumetric wear associated with use of the thirty-two-millimeter head. The result of tri-lock component can provide satisfactory clinical and radiological result.
