Abstract:
[Objective]To study the mid-term outcomes about cementless total hip arthroplasty in the treatment of patients with alcoholic osteonecrosis of the femoral head.[Method]From March 1997 to June 2002,41patients(47 hips) was treatmented by cementless total hip arthroplasty,the mid-term (equal to or more than 5 years) results were evaluated both clinically and radiographically.Clinical outcomes were evaluated according to Harris evaluation score. Components migration,bone changes around the implant were measured radiologically. Kaplan-Meier analysis was performed to evaluate the surviving rate of the femoral and acetabulum components. End point was radiographical loosening or revision of the acetabular and femoral component for any reason.[Result]Forty-seven hips in 41 patients were followed up at least 5 years. The mean Harris hip score increased from preoperation(42.4?6.4)points to (91.8?4.4) points at the time of final follow up. No component was loose,No component was revised. The focal area of pelvic osteolysis in 2 hips and small focal area of femoral osteolysis in 6 hips were found. The surviving rate of the femoral and acetabulum components,was 1.0(95% confidence interval,0.98 to 1.00).[Conclusion]The mid-term outcomes about cementless total hip arthroplasty in the treatment of patients with alcoholic necrosis of femoral head had been satisfactory. Because the wear of component,osteolysis can not be avoided,clinical and radiographical follow-up for cementless total hip arthroplasty must be carried out persistently.
