摘要
2001-01/2005-12北京积水潭医院创伤骨科行Kocher-Langenbeck入路手术的髋臼骨折患者36例,均在术前行胫骨结节或股骨髁上骨牵引,排除术后X射线片有创伤性关节炎表现、其他下肢合并损伤。应用Biodex多关节肌肉等速训练与测试系统,对患肢及健侧髋关节的外展肌群、后伸肌群在60(°)/s慢速和180(°)/s快速条件下进行等速肌力测试对比,采用可信度较高的峰力矩、总作功、平均功率等指标予以评估,两侧肌力差异≤10%为正常,≥20%为异常,11%~19%为可疑异常。结果快速测试数值显著大于相应的慢速测试数值(t=2.21,P<0.05),后伸肌群肌力的改变要显著大于外展肌群肌力的改变(t=4.33,P<0.05),提示髋臼骨折Kocher-Langenbeck入路手术中应加强对后伸肌群主要是臀大肌的保护,尽量减少其损伤,并保护肌肉血运,术后应侧重加强肌肉耐力的康复训练。
