目的　观察胫骨后肌与腓骨长肌腱对半缝合治疗小儿痉挛性马蹄内翻足的疗效。方法　先行跟腱滑动延长或腓肠肌腱膜倒“V”形切开 ,然后行胫骨后肌腱及腓骨长肌腱分别对半剖开 ,并将前者外侧半与后者内侧半在足背前外方皮下编织缝合。结果　 2 0例经平均 14个月随访 ,患儿痉挛性马蹄内翻足畸形及步态均得到较满意改善 ,优良率达 89%。结论　胫骨后肌与腓骨长肌对半缝合治疗小儿痉挛性马蹄内翻足 ,是一种安全、简便、有效的方法 Objective To observe the effect of semi-suture of the tibialis posterior muscle and peroneus longus tendon on children with spastic clubfoot. Methods Achilles tendon slide extension or gastrocnemius tendon membrane inverted “V” shape incision, and then the tibialis tendon and peroneus tendon were cut in half, and the former half of the latter and the latter half of the medial half of the latter in the dorsolateral subcutaneous skin Weaving and sewing. Results Twenty cases were followed up for an average of 14 months. The spastic clubfoot deformity and gait were all satisfactorily improved with a good rate of 89%. Conclusion It is a safe, simple and effective method for the treatment of pediatric spastic clubfoot by half tibialis posterior tibialis muscle and peroneus longus muscle
