Abstract:
Objective To evaluate the short and middle-term outcome of metal surface hemiarthroplasty in treatment of femoral head osteonecrosis. Methods Forty-one patients (forty-eight hips) with average age of 40 years were performed hemi-arthroplasties and followed up for minimum 3 years. Thirty-five cases were at the stage of Ficat Ⅲand 13 at the stage Ⅳ and their acetabular were relatively normal. Measurements of the hip reconstruction were made on the anteroposterior pelvic radiograph assisted with computer. The outcome of metal surface hemi-arthroplasty and the correlation between the orientation of the femoral component and the migration of implant was evaluated. Results The mean duration of follow-up was 5.2 years. The average UCLA hip score was improved significantly (P
