Release date: 2007-01-19 Accurately matched hemiarthroplasty for the treatment of avascular necrosis of the femoral head in order to evaluate the efficacy of a precisely matched hemiarthroplasty for the treatment of avascular necrosis of the femoral head. The investigators retrospectively analyzed the clinical data of 41 patients (48 hips) with avascular necrosis of the femoral head. There were 30 males and 11 females; the age ranged from 29 to 49 years, with an average of 37 years. Among them, Ficat III was 35 hips and Ficat IV was 13 hips. The acetabulum was relatively normal. Forty-one patients (48 hips) underwent metal hemiarthroplasty. Results All cases were followed up for an average of 5.2 years. The mean UCLA hip function score was significantly improved (P = 0.001), pain increased from 3.1 points to 9.1 points before surgery; walking increased from 4.4 points to 9.2 points, and activity increased from 5.5 points to 7.1 points. According to the UCLA score, the satisfaction rate of Ficat III 35 hips was 88.6%, and the Ficat IV 13 hips satisfaction rate was 69.2% (P = 0.25). The efficacy of the 8 hips was poor, and the UCLA hip function score was not significantly improved. Postoperative X-ray examination showed that the hips were implanted with hip varus in 7 hips (the angle between the inserted short stem and the femoral axis was less than 130°). The 5-year survival rate of the prosthesis was 83.0%. It can be seen that under the premise of strict control of surgical indications and improvement of surgical techniques, the accuracy of semi-hip surface replacement for the treatment of avascular necrosis of the femoral head is satisfactory.
