【摘要】 目的探讨采用表面置换术治疗中青年股骨头坏死的临床效果。方法对11例(14髋)Ficat分期为期或早期的股骨头坏死患者采用股骨头表面置换术,并对假体的形状进行了改进,其中男7例,女4例,年龄35~49岁。对13例(16髋)Ficat分期为期或早期股骨头坏死患者采用全髋表面置换术,其中男8例,女5例,年龄23~48岁。结果股骨头表面置换术患者术后随访1~5年,髋关节Harris评分从术前平均39分增至91分;X线片示假体无松动移位,近段股骨和髋臼无骨吸收和骨溶解,髋关节间隙除1例轻度狭窄外余均无磨损征象,无1例翻修。全髋表面置换术患者术后随访6个月~3年4个月,Harris评分从术前平均30分增至93分,有1例因技术原因术后半年假体松动而进行翻修,评为失败。结论表面置换术是治疗中青年股骨头缺血性坏死较为理想的一种方法。更多还原

【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 Satges 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 preoqeratively 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.更多还原
