We hypothesised that a femoral array placed into bone or an external (pinless) reference marker made no difference to leg length discrepancy in patients undergoing navigated total hip arthroplasty. Consecutive patients undergoing navigated total hip arthroplasty. 162 patients. No statistical difference between preoperative leg length discrepancy (p = 0.524). Mean intraoperative change was 3.7 mm and 4.6 mm (p = 0.262). The mean change in leg length measure post operatively was 4.2 mm and 4.1 mm (p = 0.656). No significant difference in leg length discrepancy between a pinless reference markers and a femoral array placed into the bone.
我们假设,对于接受导航全髋关节置换术的患者,置入骨内的股骨阵列或外部(无针)参考标记物对腿长差异并无影响。连续纳入接受导航全髋关节置换术的患者,共162例。术前腿长差异无统计学差异(p = 0.524)。术中平均变化分别为3.7毫米和4.6毫米(p = 0.262)。术后腿长测量的平均变化分别为4.2毫米和4.1毫米(p = 0.656)。无针参考标记物与置入骨内的股骨阵列之间的腿长差异无显著差异。
