摘要
对100侧成人尸体的肘部进行了解剖观察,发现旋后肌的浅深二部均有各自的起止点,可以清楚地分为两块肌肉;由 Frohse 腱弓(旋后肌弓)围成的旋后肌管上口64%近圆形,24%为卵圆形,12%为裂隙状,Frohse腱弓全长为腱性的占71%。本文以旋后肌浅部为标志,将前臂骨间后神经(PIN)分为管前段、管内段、管后段,并记录了各段的分支状况。旋后肌浅部的宽度、旋后肌管的长度与 PIN 管内段的长度三者相等。被动旋前时,可见 Frohse 腱弓对 PIN 的压迫。
One hundred cubituses of adult cadavers were dissected and observed.It wasfound that the superficial and deep parts of supinator were of separate origins andinsertions and could be clearly identified as two muscles.The upper opening ofthe supinator tunnel was encircled by Frohse's arcade which may vary in shape,being nearly circular in 64 cases,semi-circular in 24 and fissure-like in 12.TheFrohse's arcade was tendinous in 71% of the cases.Based on its course,the po-Sterior interossoous nerve can be divided into three parts:the pre-tunnel,the tu-nnel and the post-tunnel.Muscular branches arising from each part of the nervewere described.During passive full pronation of the forearm the pressure on theposterior interosseous nerve by the arcade was most obvious.
