逆行岛状V型腓骨肌皮瓣修复后足缺损的应用解剖

目的：为以逆行岛状Ⅳ型腓骨肌皮瓣修复跟骨及后足大面积软组织缺失提供解剖学资料。方法：在５０侧下肢标本、４０块跟骨上对腓骨肌皮瓣的血供、血管蒂旋转点的设定及跟骨内骨小梁的分布情况等进行了观测。结果：（１）腓动脉沿途发出７．６支肌皮支，分布到腓骨及其邻近软组织，该动脉下端与胫关、胫后动脉有丰富而粗大的吻合，完全可提供逆流供血；（２）跟骨内骨小梁的分布在不同的矢状切面上有明显的差异，这与其负重时的应分分

Applied anatomy of backfoot reconstruction by reversed island V-shaped fibular bone-myocutaneous flap

Objective:To provide anatomical basis for repairing calcaneus and serious tissue defect in backoot by reversed island V shaped fibular bone myocutaneous flap pedicled with peroneal vessels.Methods:The blood supply of fibular bone-myocutaneous flap was observed and the reversed point of pedicle were designed on 50 sides of low limb specimens.The trabecular distribution of calcaneus was observed on 40 calcaneus.Results:Peroneal artery gave off 7.6 branches to fibula and neighborhood soft tissue.It has plenty of anastomosis with anterior and posterior tibial artery,and the large co-mmunication branches could provide reversed blood supply completely.The trabecular distribution changed significantly with different sagittal planes.It related with the stress distribution of body wight.Conclusions:The V shaped fibular bone myocutaneous flap pedicled with peroneal vessels could be used for repairing serious tissue defect in the backfoot.A good result has been obtained in clinic.
