摘 要:
[目的]探讨非影像手术导航系统下进行全髋关节表面置换的方法和疗效。[方法]11例（16髋）在导航系统下进行全髋关节表面置换术，设定髋臼假体最佳植入角度为外展角45°，前倾角15°，股骨假体柄颈角为0°，柄干角140°。术后测定假体植入的角度情况，统计手术时间、出血量。[结果]术后手术导航系统植入髋臼假体的前倾角为（15．6±1．2）°、外展角为（45．3±1．5）°，股骨假体柄颈角为（2．2±1．8）°，柄干角为（140．5±2．0）°。平均随访2．5年（40～15个月），术前平均Harris评分35分（25—35分），术后为X线片发现1例髋臼假体周围出现透亮线，而无松动迹象。[结论]非影像手术导航系统下可以精确地植入假体，减少假体松动的发生，具有重要的临床价值。[著者文摘]

Abstract:
[ Objective ] To study the method and curative effect of total hip surface replacement using non-image based surgical navigation system. [Methods] Eleven patients （16 hips） with femoral head osteonecrosis were operated by using nonimage based surgical navigation system. According to the design of the study, the acetabular component was placed in best inclination of 45° and best anteversion of 15°, femoral component was placed in best stemfemoral angle of 140°. Postoperative component position was measured. The operative time and hemorrhage were calculated. Patients were evaluated by radiographys and Harris＇s hip score. [ Results ] The post-operative anteversion, inclination, stem-nech angle and stem-shaft angle reached （ 15. 6 ± 1.2 ）°, （45. 3± 1.5 ）°, （2. 2± 1.8 ）° and （ 140. 5± 2. 0）°. The mean duration of follow-up was 2. 5 years. The average Harris＇s hip score was improved significantly from 35 （25 - 45 ） to 95 （ 85 - 100）, 14 hips were excellent and 2 hips were good. The average operative time was 90 rain （80 - 105 min） . The average hemorrhage were 30 ml （20 -45 ml）. Radiolucent line existed around 1 acetabular prostheses but no became flexible. [ Conclusion] The prostheses can be planted accurately by non-image based surgical navigation system in the total hip surface replacement. It can reduce prostheses flexible and has important clinic value.[著者文摘]
