【摘要】 目的 :为带三角肌前束肌蒂锁骨瓣转位术提供解剖学基础。方法 :在 5 0侧成人上肢标本上解剖观测三角肌前束形态 ,血供及其与锁骨的关系。结果 :三角肌前束前缘平均长 16.5cm ,前束在与中间束交界处长 14 .6cm ,前束起始于锁骨部宽 5 .9cm。神经血管束入肌门的体表投影点在肩峰角下 5 .6cm ,约在前束前缘外后方 3 .5cm。肌蒂游离长度达 12 .6cm。结论 :可设计以三角肌前束为蒂的锁骨瓣转位修复肱骨上段骨不连、骨缺损及软组织缺损。更多还原

【Abstract】 Objective:To provide anatomic basis for clavicular flap pedicled with anterior bundle of deltoid muscle (ADM).Methods:Morphology,blood supply and the relationship to clavicle were observed on 50 sides adult arm specimens.Results:The average length of ADM is 16.5 cm,and it is 14.6 cm between the boundary of ADM and middle bundle of deltoid muscle.The ADM is 5.9 cm as it originated from clavicle.Neurovescular tract went into hilus of muscle at 3.5 cm postlateral of anterior border of ADM.Conclusion:Transposition of clavicular flap pedicled with anterior bundle could be used to repair bone nonunion,bone defect and soft tissue defect.更多还原
