【摘要】：目的为穿支蒂足背中间皮神经营养血管皮瓣修复前足软组织缺损提供解剖基础。方法在30侧动脉内灌注红色乳胶的成人足标本上解剖观测:1足背中间皮神经的走行与分布;2足底弓第3足背穿支及其与足背中间皮神经营养血管间吻合关系。另在1侧新鲜标本上进行摹拟手术设计。结果 1足背中间皮神经主要为腓浅神经外侧支的延续,经十字韧带表面,径直前行至第4跖骨间隙近端附近分为第3、4跖背支,分布于部分足背和趾背皮肤;2足背中间皮神经营养血管为多节段、多源性,与术式关系密切在第4跖骨间隙近端浅出的足底弓第3足背穿支位置相对恒定,并分出众多的细小血管与足背中间皮神经干或旁营养血管链的分支密切吻合。结论可形成以足底弓第3足背穿支蒂足背中间皮神经营养血管皮瓣转位修复前足软组织缺损。
[Abstract]:Objective to provide anatomic basis for repairing soft tissue defect of forefoot with perforator pedicled medial cutaneous neurovascular flap. Methods Anatomical observation was performed on 30 adult foot specimens infused with red latex into the artery to observe the movement and distribution of the middle cutaneous nerve of 1 foot and the anastomosis between the dorsal perforating branch of the third plantar arch and the nutrient vessels of the middle cutaneous nerve of the dorsalis pedis. In addition, a mimic surgical design was performed on one fresh specimen. Results 1 the medial cutaneous nerve of the dorsalis pedis was mainly the extension of the lateral branch of the superficial peroneal nerve. The neurotrophic vessels of the middle cutaneous nerve of the dorsalis pedis were multisegmental and multisource distributed in the skin of partial dorsal foot and dorsal toe of foot. The position of the third dorsal perforating branch of the foot arch was relatively constant in the proximal space of the fourth metatarsal bone. The small vessels were closely anastomosed with the branches of the trunk of the medial cutaneous nerve of the dorsalis pedis or the branches of the vegetative vascular chain. Conclusion the pedicle of the third foot dorsal perforating branch can be used to repair the soft tissue defect of the forefoot by transposition of the medial cutaneous neurovascular flap pedicled with the third plantar arch.
