Electromyographic and clinical studies were performed on patients undergoing total hip replacement by the modified direct lateral (29 hips), the direct lateral (29 hips) and the posterior approaches (21 hips). Assessments were made three months after operation. The Trendelenburg test was positive (Grade II) in eight cases operated upon by the direct lateral route, but in only one of each of the other two groups. Denervation occurred in only five of the 28 hips with abductor weakness without statistical difference between the groups. In the modified direct lateral group, radiological evidence of union of the trochanteric sliver was associated with significantly better abductor function than in those with malunion or non-union.
对采用改良直接外侧入路（29髋）、直接外侧入路（29髋）和后入路（21髋）进行全髋关节置换术的患者进行了肌电图和临床研究。术后三个月进行评估。直接外侧入路手术的8例患者Trendelenburg试验呈阳性（Ⅱ级），但其他两组各仅有1例阳性。28例存在外展肌无力的髋关节中仅有5例发生去神经支配，各组之间无统计学差异。在改良直接外侧入路组中，转子骨块愈合的影像学证据显示外展功能明显优于骨块愈合不良或未愈合的患者。
