OBJECTIVE
The objective of this study was to determine the frequency and anatomical characteristics of Struthers' ligament and the supracondylar humeral process and evaluate the clinical implications in compressive neuropathy of the median nerve .
METHOD
We dissected 60 arms from 30 cadavers (26 males and 4 females): 15 were previously preserved in formalin and glycerin and 15 were dissected fresh in the Anatomy Laboratory for this paper. The relationships between Struthers' ligament and the median nerve and brachial artery and veins were documented with drawings and photos .
RESULTS
The supracondylar humeral process was not found in any of the 60 dissected arms. Struthers' ligament was identified in six arms (two bilateral); in all cases high insertion of the pronator teres muscle was observed .
CONCLUSION
Struthers' ligament is an aponeurotic structure that may or may not be associated with the supracondylar humeral process, and is an important potential site of median nerve compression in the lower third of the arm. Level of Evidence IV, Case Series.
目的
本研究的目的是确定斯特鲁瑟斯韧带和肱骨髁上突的发生率及解剖特征，并评估其在正中神经压迫性神经病中的临床意义。
方法
我们从30具尸体（26例男性和4例女性）上解剖了60只手臂：15只先前保存在福尔马林和甘油中，15只为撰写本文在解剖实验室新鲜解剖。用绘图和照片记录斯特鲁瑟斯韧带与正中神经、肱动脉和静脉之间的关系。
结果
在解剖的60只手臂中均未发现肱骨髁上突。在6只手臂（2例双侧）中发现了斯特鲁瑟斯韧带；所有病例均观察到旋前圆肌高位附着。
结论
斯特鲁瑟斯韧带是一种腱膜结构，可能与肱骨髁上突有关，也可能无关，是手臂下三分之一处正中神经受压的重要潜在部位。证据等级IV，病例系列。
