【摘要】 观测了50侧成人上肢的骨间前神经及其周围结构。讨论了骨间前神经综合征发生和易于误诊的形态学原因以及施行手术时的注意事项。骨间前神经的分支3/4在近侧部入肌,10%的个体与尺神经有吻合,6%的旋前方肌支为双支,38%有拇长屈肌副头。手术切口范围应在肱骨内,外上髁连线远侧39.6±12.6mm之外。此外,还提到了旋前方肌支与鱼际肌支的吻接等问题。更多还原

【Abstract】 On 50 upper limbs of adult cadavers,the anterior interosseous nerve and its adjacent struc-tures were observed and measured.The anatomic causes of anterior interosseous nerve syndrome,its erroneous diagnosis and some notification in operation were discussed.75% of the branchesfrom the anterior interossous nerve entered muscles proximally.10% of the anterior interosseousnerves anatomose with ulnar nerve. 6% of them send double branches to quadrate pronator mus-cle,and 38%of the collateral caputs of long flexor muscle of the thumb receive branches from thenerve.For clinical application,it was suggested that the incision should be 39.6±12.6mm distalto the line between the external and internal epicondyls of humerus.Opreation concerning thetransposition of quadrate pronator branch of anterior interossous nerve to bridge the thenar mus-cle branch of median nerve were discussed.更多还原
