摘要
目的剖析拇趾腓侧皮瓣修饰再造拇手指的应用解剖,改进切取拇趾腓侧皮瓣计算公式。方法对30例侧成人下肢标本和60例侧足趾移植病例的跖背、跖底血管进行解剖,对趾底动脉进行分型。对先期修饰性再造的14指的挛缩皮瓣进行研究,改进拇趾腓侧皮瓣计算公式。结果提出跖背动脉细浅支的存在,跖背动脉细浅支的出现率为17.8%,转归分为Ⅰ、Ⅱ、Ⅲ型。趾底固有动脉来源分为Ⅰ、Ⅱ、Ⅲ、Ⅳ型。拇趾腓侧皮瓣再植后挛缩度约15%,按改进后的计算公式切取的皮瓣克服了挛缩弊端。结论拇趾腓侧皮瓣的主要供血源为趾底动脉,跖背动脉细浅支不足以为拇趾腓侧皮瓣供血。改进后的皮瓣修饰再造的拇手指外形接近手指。
Objective To improve the calculation formula of cutting fibula side flap of great toe by analyzing its applied anatomy on reconstruction of thumb or fingers.Methods The 30 specimen of adult lower extremities and 60 cases of dorsal or base metatarsal arteries were typed.At the same time,14 cases of modified fibula side flaps of great toe contractured were investigated on reconstructed fingers. Results Superficial branch of dorsal metatarsal artery was founded which can be divided into typeⅠ,Ⅱand Ⅲ, and its occurrence rate was 17.8%. The inherent artery of base metatarsus can be grouped into typeⅠ,Ⅱ,Ⅲ and Ⅳ. The contracture rate of flap is 15%. Many complications can be avoided with improved formula in flap cutting. Conclusions The main blood supply on fibula side flap of great toe is from the base metatarsal artery,and the superficial branch of dorsal metatarsal artery is miner. The reconstructed thumb or fingers like the original ones with the improved flap.
