摘要(Abstract)：

[目的]探讨在小切口人工全髋关节置换术中使用计算机导航对于提高髋臼置入精确度的意义。[方法]2008年7月～2009年10月对56例髋关节病变患者(均为单侧髋)采用小切口人工全髋关节置换术,其中使用计算机导航辅助手术组26例26髋,男14例,女12例,平均年龄(65±14.3)岁,未使用计算机的传统小切口手术组30例30髋,男19例,女11例,平均年龄(67±12.9)岁。比较两组病例切口长度、手术时间、术中出血量、术后引流量、术后Harris评分、并发症及髋臼假体角度,分析小切口人工全髋关节置换术中使用计算机导航的临床意义。[结果]两组在手术时间及术后Harris评分方面无统计学差别。手术切口导航组(4.9±0.65)cm,明显小于传统组(8.0±0.85)cm,差异具有统计学意义(P<0.05)。导航组术中失血量为(373.9±124.55)ml,术后引流量(488.9±225.36)ml,明显小于传统组术中失血(513.7±121.92)ml及术后引流(628.7±193.96)ml,差异均具有统计学意义(P<0.05)。导航组术后所测前倾角为(15.5±2.2)°,外展角为(41.0±1.6),传统组分别为(19.4±2.5)°和(45.5±2.0)°,差异均具有统计学意义(P<0.05),且导航组术后所测数值更集中于术前所设定的理想值(术前设定理想的前倾角为15°,外展角40°)。导航组术后1例发生大转子骨折无移位,传统组术后1例发生假体下骨折,其余病例均无并发症。[结论]小切口全髋关节置换术中,采用计算机导航可进一步减少手术创伤并提高髋臼的置入精度。
