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.
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.
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.
Hip resurfacing operations may be the most effective treatment for avascular necrosis of the femoral head in the young and middle aged patients.
探讨表面置换术治疗中青年股骨头缺血性坏死的早期临床效果。
对11例Ficat III-IV期股骨头缺血性坏死患者（14髋）行股骨头表面置换手术。11例中，男性7例，女性4例。年龄范围为35至49岁。另13例Ficat III-IV期股骨头缺血性坏死患者（16髋）行全髋关节表面置换术，13例中，男性8例，女性5例。年龄范围为23至48岁。假体根据中国人的解剖特点进行了改进。
行股骨头表面置换手术的患者随访1至5年。Harris髋关节平均评分由术前39分提高至术后91分。行全髋关节表面置换手术的患者随访6至40个月。Harris髋关节平均评分由术前30分提高至术后93分。
髋关节表面置换手术可能是治疗中青年股骨头缺血性坏死的最有效方法。
