带感觉神经的足背动脉蒂跗外侧动脉皮瓣修复前足缺损

目的探讨前足皮肤缺损的修复及感觉功能恢复的方法。方法在足背外侧设计以足背动脉为蒂的跗外侧动脉皮支穿出点为中心的逆行皮瓣修复前足皮肤缺损，用足背外侧皮神经与跖底神经吻合，足外侧供区用腹股沟全厚皮打包植皮。结果17例跗外侧动脉皮瓣及植皮全部成活，感觉、外形良好、不需要二期整形。结论跗外侧动脉皮瓣逆行转移修复前足皮肤缺损，皮瓣薄、有神经支配、解剖位置恒定。

Lateral tarsal artery flap with dorsal lateral cutaneous nerve to close forefoot cutaneous defect

Objective To investigate the clinical method of closing defect and regain the sensory on forefoot injury. Methods Lateral tarsal artery flap was designed as a reverse flow flap to close forefoot defect in dorsal lateral foot while perforating hranche of lateral tarsal artery as turning point. Lateral cutaneous nerve was inosculated to lateral plantar fascia. Donor site was covered by skin-grafting. Results seventeen cases survived satisfactorily with good shape and regaining sensory. Conclusion Lateral tarsal artery flap can be used in coveraged of forefoot defect. Lateral tarsal artery flap was thin flap with good shape and to regain the sensory of forefoot.
