电刺激定位法修复腕部正中神经损伤

Median nerve of the wrist repair with electrical fuscicular orientation

目的 :阐明神经束支定位法在远端正中神经损伤修复中的作用。方法 :选择 44例远端正中神经损伤病例 ,进行神经内束支分离 ,双极电刺激定位后束膜吻合 ,与 17例外膜吻合组对照。结果 :束支分离定位法在远端正中神经损伤修复中的成功率为 88.6 % ,治疗组较对照组感觉恢复率有提高 ,但无明显差异 ( P>0 .0 5 ) ,运动功能恢复率显著提高 ( P<0 .0 1)。结论 :神经内束支分离定位应用于远端正中神经损伤修复是可行的 。

Objective:To clarify the effects of fascicular orientation in repairing low median nerve injuries.Methods:44 low median nerve injuries were repaired using end-to-end fascicular suture after intraneural fascicular dissection and electrical fascicular orientation. The control group was 17 nerve injuries repaired with epineurial sutare.Result:Satisfactory result were obtaines in 39 cases of low median nerve injuries. The sensory recovery in treatment group was faster than in control group, but no significant diference (P>0.05).Better motor functions were achieved in treatment group(P<0.01).Conclusion:Intraneural fascicular disseciton and electrical fascicular orientation is useful for treating low median nerve injuries,and has a good recovery of nerve functions.
