摘要： 目的探讨腓肠肌肌支神经转移术修复腓深神经损伤的可行性和有效性。方法32 只成年雌性Sprague-Dawley 大鼠分成空白组、对照组、神经直接吻合组(腓深神经直接吻合)和神经转移组(腓肠肌外侧头肌支转移至腓深神经)，每组各8 只。术后12 周，肉眼观察神经吻合口生长情况，测量胫神经各肌支长度(L1)、入肌点处直径(D1)、各肌支起点至腓骨颈平面的距离(S)，腓总神经膜内可分离的最大长度(L2)、腓深神经的直径(D2)，比较手术前后大鼠患肢腓神经功能指数(PFI)、复合肌肉动作电位(CMAP)波幅、神经传导速度(NCV)、胫前肌湿重、肌酸磷酸激酶(CK)酶活性。结果所有实验大鼠均L10.05)。结论腓肠肌外侧头肌支神经转移至腓深神经修复腓深神经在解剖上可行，但要实现无张力吻合需要将腓总神经向近端进行神经膜内无损伤分离。腓肠肌外侧头肌支神经转移术能有效恢复腓深神经功能。

Abstract: Objective To explore the feasibility and effectiveness of lateral gastrocnemius muscle branch nerve transferring for deep peroneal nerve injury. Methods Thirty-two adult female Sprague-Dawley rats were divided into control group (n=8), sham group (n=8), nerve direct repairing group (n=8) and nerve transferring group (n=8). Twelve weeks after the anastomosis, the nerve anastomosis was observed visually, the length of lateral of gastrocnemius muscle branch (L1), the diameter at the point of entering muscle (D1), the maximum detachable length of nervus peroneus communis (L2), the diameter of deep peroneal nerve (D2) and the distance between branch point and neck of fibula (S) were measured. The peroneal nerve functional index (PFI), the amplitude of compound muscle action potential (CMAP), nerve conduction velocity (NCV), the weight of the tibialis anterior and the creatine kinase (CK) activity of theanterior tibial were compared among groups. Results L10.05). Conclusion It is feasible that lateral head muscular branches of gastrocnemius nerve transferring can repair deep peroneal nerve injury, which is needed to separate superficial peroneal nerve and deep peroneal nerve in the epineurium without damaging nerve for tension free neuroanastomosis. Lateral head muscular branches of gastrocnemius nerve transferring can repair the function after deep peroneal nerve injury.
