摘要
目的探讨正中神经的分支旋前方肌肌支和拇短屈肌肌支移位修复尺神经深支的解剖学依据。方法选择新鲜成人上肢标本8侧,通过对标本进行显微解剖和模拟手术,评估两种神经移位术供受体神经是否匹配以及神经再生距离缩短的程度。数据通过SPSS17.0软件进行分析。结果拇短屈肌肌支和旋前方肌肌支移位术供受体神经纤维数量差异均有统计学意义(P<0.05),两者极大缩短神经再生距离至(37.30±5.76)mm和(74.44±8.90)mm。结论旋前方肌肌支和拇短屈肌肌支移位修复尺神经深支术的共同优点是极大缩短神经再生距离,但是两者神经纤维数量与受体神经均存在差异。
Objective To explore the anatomical basis for the pronator quadratus branch and the flexor pollicis brevis branch transfer to the deep branch of ulnar nerve. Methods Eight fresh upper limb were dissected and observed. Then the transfer operation on the cadaver were imitated. The regenerating distance were recorded and nerve fiber were calculated. All data were analyzed by SPSS17.0. Results The nerve fiber number existed significant differences between the donor and the recipient nerve of both operation（P〈0.05）. The regenerating distance of the flexor pollicis brevis branch and the pronator quadratus branch were（37.30±5.76） mm and（74.44±8.90） mm. Conclusion Both of the pronator quadratus branch and the flexor pollicis brevis branch transfer to the deep branch of ulnar nerve can provide a short regenerating distance, but neither could provide enough nerve fiber.
