以跗外侧动脉为蒂骰骨瓣转位修复距骨颈骨折的应用解剖

Transposition of cuboid bone flap pedicled with lateral tarsal artery for the repair of talus neck fracture:An anatomical study

在30侧下肢标本上解剖观测了骰骨背侧面血管的来源、走行、分支和分布。骰骨背侧面的动脉主要来自跗外侧动脉。该动脉穿趾短伸肌深面,紧贴骰骨背侧面中份行走。行经骨面时,发出5～12支管径在0.3～1.0mm 至骰骨。以跗外侧动脉为蒂的骰骨瓣大小约为2×1cm。经临床应用证明,本骨瓣是修复距骨颈骨折距骨体缺血性坏死简易可行的一种新术式。

The blood supply(origin,course,branches and distribution)to the do-rsum of cuboid bone was observed on30 adult cadaveric feet.The lateraltarsal artery is the main supporter ofthe part.The artery penetrates deepto the extensors digitorum brevis andpresses close to the middle part of thebone.It distributes 5 to 12 branchesto the dorsal side of the cuboid bone.The cuboid bone flap of 2×1cm insize,pedicled with the lateral tarsalartery,could be transposed to repairtalus neck fracture and ischemic nec-rosis of talus body.Clinical applica-tion showed a satisfactory result forthe new feasible operat actory method.
