In a prospective study 50 extremities in 46 patients with total hip replacement (THR) were examined clinically and with EMG preoperatively and 4 weeks postoperatively. Four patients with normal preoperative findings had electromyographical evidence of nerve lesions postoperatively and three of these had clinical symptoms; one patient had no clinical symptoms. Ten patients with normal pre- and postoperative findings were re-examined 1 year after the operation and still found to be normal. In 150 records of patients with THR reviewed retrospectively, only one doubtful case of nerve lesions was found.
在一项前瞻性研究中，对46例行全髋关节置换术（THR）患者的50个肢体在术前及术后4周进行了临床检查和肌电图检查。4例术前检查结果正常的患者术后有神经损伤的肌电图证据，其中3例有临床症状；1例无临床症状。10例术前和术后检查结果均正常的患者在术后1年进行复查，结果仍正常。在回顾性分析的150例THR患者记录中，仅发现1例可疑神经损伤病例。
