Objective To investigate the early clinical effect of resurfacing arthroplasty on the treatment of avascular necrosis of the femoral head in the young and middle-aged patients. Methods Eleven patients with avascular necrosis of the femoral head in Ficat Stages Ⅲ -Ⅳ(14 hips)were treated by femoral head resurfacing operations. Of 11 cases, there were 7 males and 4 females. With an age range of 35 to 49 years.While 13 patients with avascular necrosis of the femoral head in Ficat Satges Ⅲ-Ⅳ (16 hips) were treated by total hip resurfacing arthroplasty of 13 cases there were 8 males and 5females. With an age range of 23 to 48 years. The prostheses were improved in light of the anatomic features of the Chinese. Results These patients treated by femoral head resurfacing operations were followed up for 1 to 5 years. The average Harris hip score was increased from 39 points preoperatively to 91 points postoperatively. These patients treated by total hip resurfacing operations were followed up for 6 to 40 months. The average Harris hip score wasincreased from 30 points preoperatively to 93 points postoperatively. Conclusion Hip resurfacing operations may be the most effective treatment for avascular necrosis of the femoral head in the young and middle aged patients.
