为肩周炎有关诊治提供结节间沟滑液鞘和肩峰下囊的资料,本文观测了30侧成人肩关节标本,剖检前用有色明胶溶液分别注射到肩峰下囊和肩关节腔内。 一:结节间沟滑液鞘 肱二头肌长头腱起自肩胛骨盂上结节,通过肩关节的关节腔,其腱周包有滑膜,并随肌腱伸出关节囊达给节间沟处,即结节间滑液鞘。从肱骨大结节上缘中点开始测量,此鞘平均长度4.4cm,均与肩关节腔相通。结节间沟的沟嵴上有薄层横韧带将肌腱限制在沟内。 For the diagnosis and treatment of frozen shoulder to provide information on the inter-nodular sulcus and subacromial sulcus, 30 adult specimens of the shoulder were observed. Before dissection, colored gelatin solution was injected into the subacromial sac and shoulder joint cavity Inside. A: nodular groove synovial fluid sheath biceps long tendon from the scapula upper nodules, through the joint cavity of the shoulder joint, the tendon peritoneal synovium, and with the tendon sticking out of the joint capsule to the internode Gully, that is, nodular synovial sheath. Measured from the midpoint of the upper edge of the humerus large nodule, the sheath average length of 4.4cm, are connected with the shoulder joint cavity. There are thin transverse ligaments on the ditch ridge of the nodules that restrict the tendon to the ditch.
