肱骨二头肌沟及其腱鞘的观察

Observation of bicipital groove and the tendon sheath of biceps brachii

在181侧成人干燥肱骨及30侧上肢标本观察了二头肌沟的形态及肱二头肌长头腱鞘的构造。沟可分为浅沟、中间及深沟型。沟内侧壁与肌腱的关系更为密切。小结节上方有一滑膜皱襞加强内侧壁。腱鞘的内侧壁长于外侧壁。讨论了其功能和临床意义。

The shape of the bicipital grooveof humerus and the structure of thetendon sheath of biceps brachii werestudied on 181 adult humeri and 30adult upper extremities.There arethree types of bicipital groove,namely,the shallow,the intermediate and thedeep ones.The medial wall of thetendon sheath is longer than that ofthe lateral one and is strengthened bya synovial fold above the lesser tube-rosity.
