旋腓骨颈动脉蒂腓骨上段骨瓣的应用解剖学研究

Applied anatomy of upper fibular bone flap pedicled with circumflex fibular neck artery

目的为以旋腓骨颈动脉为蒂腓骨上段骨瓣的设计提供应用解剖学基础。方法在54侧经动脉内红色乳胶灌注的成人下肢标本上,重点观测旋腓骨颈动脉的起始、走行、分支、分布和吻合。结果旋腓骨颈动脉始于胭动脉,起点在腓骨头尖下(3．3±1．1)cm,干长(1．4±1．0)cm,外径(1．4±0．5)mm,其上行骨膜支与膝下外侧动脉下行骨膜支有恒定吻合。结论以旋腓骨颈动脉为蒂的腓骨上段骨瓣移植术具有手术的可行性。

Objective To provide applied anatomy basis for upper fibular bone flap pedicled with circumflex fibular neck artery, Methods The origin, course, branches, distribution and anastomosis of circumflex fibular neck artery were observed on 54 sides of adult cadaver lower limb specimens perfused with red latex, Results The circumflex fibular neck artery derived from popliteal artery （ 3. 3 ± 1.1 ） cm beneath the tip level of fibular head, with its length of （ 1. 4± 1.0） cm and diameter of （ 1.4 ±0. 5 ） mm, The ascending periosteal branches of circumflex fibular neck artery anastomosed consistently with the descending periosteal branches of inferior lateral genieular artery, Conclusion The transplanting operative design of upper fibular bone flap pedieled with circumflex fibular neck artery was feasible.
