摘要
目的：为带血供肱骨下段骨瓣移位术提供解剖学基础。方法：４０侧成人上肢标本，观测尺侧下副动脉、尺侧返动脉的起始、走行、分支分布、骨膜支和吻合。结果：尺侧下副动脉距髁间连线上３．７±１．７ｃｍ始于肱动脉，外径１．８±０．４ｍｍ，长１．８±０．７ｃｍ，骨膜支１～３支，外径０．８±０．４ｍｍ分布肱骨下段内侧半骨膜。尺侧返动脉前干外径１．１±０．２ｍｍ。尺侧上副动脉、尺侧下副动脉、尺侧返动脉在肱骨内上髁附近互相吻合。结论：利用上述血管吻合关系，设计带血供的肱骨（膜）瓣或骨皮瓣，可移位修复肱骨中上段、尺、桡骨中段骨折骨不连。临床应用已取得良好效果。
Objective:To provide anatomy basis for the transposition of pedicled medial lower part of humerus bone flap.Methods:The origin,course,branch distribution and anastomosis of inferior ulnar collateral artery and ulnar recurrent artery were observed on 40 adult cadaver upper limb specimens.Results:The inferior ulnar collateral artery originates from brachial artery 3.3±1.2 cm above the line between the medial and lateral epicondyles,with a diameter of 1.8±0.4 mm and a length of 1.9±0.6 cm.It gives off 1～3 periosteal branches to the medial lower part of humerus with a diameter of 0.8±0.4 mm.The anterior branch of ulnar recurrent artery is 1.1±0.2 mm in diameter.The superior ulnar collateral artery,the inferior ulnar collateral artery and the ulnar recurrent artery are anastomosis near the medial epicondyle of humerus.Conclusions:A periosteal flap or bone-skin flap in the medial lower humerus region could be designed for transfering to repair nonunions in the upper middle humerus region and the middle part of ulna or radius.Satisfactory results were achieved in clinic.
