We studied the hip abductor strength and Trendelenburg test prospectively in 100 patients undergoing total hip replacement via a lateral or posterior approach. In 49 patients, we used the lateral approach to implant the Charnley total hip replacement, and in 51 patients, the posterior approach to implant the Exeter total hip. Isometric abductor strength was measured with the kinetic communicator device and the Trendelenburg test was recorded preoperatively and at 3 and 12 months postoperatively. Of the original 100 patients, 83 were available for study at 3 months and 73 at 12 months. Hip abductor strength and the Trendelenburg test improved postoperatively in both groups, but we found no difference in hip abductor strength recovery at 3 and 12 months between the lateral approach and the posterior approach. Similarly there was no difference in the Trendelenburg test between the two groups 3 and 12 months following hip replacement.
我们对100例经外侧或后侧入路行全髋关节置换术的患者进行了前瞻性的髋外展肌力量及特伦德伦伯格试验研究。其中49例患者采用外侧入路植入Charnley全髋关节假体，51例患者采用后侧入路植入Exeter全髋关节假体。使用动力学通信设备测量等长外展肌力量，并在术前、术后3个月和12个月记录特伦德伦伯格试验结果。在最初的100例患者中，83例在术后3个月可供研究，73例在术后12个月可供研究。两组患者术后髋外展肌力量及特伦德伦伯格试验均有改善，但我们发现外侧入路和后侧入路在术后3个月和12个月时髋外展肌力量恢复情况无差异。同样，在髋关节置换术后3个月和12个月时，两组患者的特伦德伦伯格试验也无差异。
