胫神经腓肠肌内侧头肌支切断的小腿减肥术

Neurotomy of the motor branches of tibial nerve innervating the medial gastrocnemius muscle for calf reduction

目的探索缩小小腿腓肠肌改善小腿外形的手术方法.方法通过窝皮肤皱襞4～5cm横切口,切断胫神经腓肠肌内侧头肌支,使腓肠肌内侧头失神经萎缩,达到小腿减肥的目的.测量并记录小腿周径和外形的变化.结果本组16例患者行胫神经腓肠肌内侧头肌支切断术后,小腿最大周径平均缩小（3.5±1.1）cm.小腿内侧曲线变得平缓.患者术后可立即下地行走,无明显肿胀.随访半年,站立、行走等日常活动未受影响.结论行胫神经腓肠肌内侧头肌支切断术,可缩小小腿,改善小腿外形,方法简便、安全,效果明显,同时不影响患者的行走功能.

Objective To evaluate a method to reduce the volume of gastrocnemius muscle for calf reduction. Metlaeds The motor branches of tibial nerves to medial the gastrocnemius muscle were explored and cut off through a 4-5 cm long incision at popliteal crease. The circumference and the shape of the leg were measured and recorded. Results Nettrotomy of the nerve to medial the gastrocnemius muscle was performed in 16 cases. After operation, the circumference of the leg was reduced （3.5 ± 1.1 cm averagely） and the curve of the medial line of the calf was reduced. There is no obvious swelling in these cases and the patients were able to walk immediately after operation. The function of the leg was not obviously influenced. Conclusion Neurotomy of the nerve to the medial gastrocnemius muscle was a safe and effective method for calf reduction.
