    Abstract:
    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 Stages III - IV (16 hips) were treated by total hip resurfacing arthroplasty of 13 cases there were 8 males and 5 females. 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 was increased 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.
