O3366 CHARNLEY-KERBOULL TOTAL HIP ARTHROPLASTY FOR AVASCULAR NECROSIS OF THE FEMORAL HEAD. A MINIMUM 10-YEAR FOLLOW-UP STUDY



Abstract

Aims: The purpose of this retrospective study was to report on the minimum 10-year follow-up results of a consecutive series of cemented low friction total hip arthroplasties performed for avascular necrosis of the femoral head. Methods: One hundred and twenty-two THAs in 96 patients were performed between January 1980 and December 1990. All prostheses were of Charnley- Kerboull design, combining a 22.2-mm femoral head and an all-polyethylene socket. Both components were cemented. The mean age of the series was 50.8 ± 13.3 years (21–85 years). Eighty hips were graded Ficat III and 42 hips were graded Ficat IV. Results: At the minimum 10-year follow-up evaluation, 59 patients (75 hips) were still alive and had not been revised at a mean of 13.9 years (10–21 years), 7 patients (7 hips) had been revised, 20 patients (24 hips) had died from unrelated causes, and 10 patients (16 hips) were lost to follow-up. The mean dñAubignŽ hip score was 17 ± 1 at the latest follow-up. The mean wear rate for unrevised hips was 0.07± 0.06 mm per year. Revision was performed for polyethylene wear associated with periprosthetic osteolysis in 6 hips and for deep sepsis in one. Three hips had recurrent dislocations. The survival rate at 15 years, using revision for any reason as the end-point, was 88.5% (95% conþdence interval, 80.2 to 96.9%). Conclusions: This series indicated that Charnley Kerboull low friction total hip arthroplasty for avascular necrosis could provide satisfactory long-term clinical and radiologic results.
