摘　　要：目的探讨虚拟影像导航辅助下全髋关节置换的方法和疗效。方法对13例(15髋)髋关节产疾患,在导航系统下进行小切口微创全髋关节表面置换术。术前髋关节平均Harris评分40分(25～50分),采用改良Hardinge手术入路,统计手术时间、出血量。术后进行Harris评分分析和X线检查。结果在导航系统下顺利完成微创全髋关节置换,平均手术时间为90min(80～105min),出血量为300ml(200～450ml)。术后Harris评分为90分(80～110分),优14髋,良1髋。平均随访2年(10～40个月),X线摄片发现1例髋臼假体周围出现透亮线,但无松动迹象。结论虚拟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。Objective To study the method and curative effect of virtual image- guided total hip arthroplasty. Methods Fifteen patients （15 hips） underwent virtual image- guided total hip arthroplasty. The preoperative average Harris hip score was 40. The modified Hardinge approach was used. Patients were evaluated by Harris hip score and radiography. Results Total hip arthroplasty succeeded in 18 hips by navigation. The average operative time were 90 min （85--100 min）. The average hemorrhage were 300 ml （200--450 ml）. The average incision length were 7.5--8.5 cm. The average VAS were 3.5. The postoperative average Harris hip score was 90, 14 hips were excellent, and 1 hip was good. The mean duration of follow- up was 2 years （10--40 months）. Radiolucent line existed around 1 acetabular prosthesis but none became loosening. Conclusion The prostheses can be implanted accurately by non- image based surgical navigation system in the total hip replacement. Navigation system which can reduce loosening of prostheses has important clinic value.
