摘要
观察40侧成人手标本,第一掌背动脉是第二掌骨背桡侧的主要血供来源,可分3种类型.可以第二掌背动脉为蒂,第二、三掌骨近端和远端骨瓣转位.修复陈旧性手舟骨骨折。文中讨论了与该术式有关的应用解剖学要点.
On 40 hand specimens of adultcadavers,the second dorsal metaca-rpal artery was observed to bedistributed on the radial-dorsal sideof the second metacarpal bone and onthe radial-dorsal side of the thirdmetacarpal bone.The dorsal metaca-rpal artery,which is 0.6mm indiameter and has three variations,can be used as the vascular pediclefor the transposition of the proximalor distal portion of the secondor the third metacarpal bone forrepairing old scaphoid fracture.Forproximal metacarpal bone flap,thevascular pedicle should be freed for2.5 to 3.0cm in length,and turneddeeply around the tendon of longradial extensor muscle of wrist.Fordistal metacarpal bone flap,thevascular pedicle is long enough to thescaphoid bone.
