The authors present a case where the main variants of the humerus were associated on the same specimen: the supracondylar process and the supratrochlear foramen. The supracondylar process, a bony prominence situated on the anteromedial surface of the humerus in the vicinity of the medial epicondyle, could be at the origin of ulnar or median nerve and brachial artery compression syndromes, especially when associated with Struthers' ligament.
The anatomic specimen was discovered accidentally during a larger study aimed at establishing a current norma anatomica and morphometry of the humerus. The supracondylar process and the supratrochlear foramen were morphologically and morphometrically analyzed.
The supracondylar process was situated on the anteromedial surface of a left humerus, roughly 5 cm above the medial epicondyle. It was 12.4 mm in length, mediodistally directed. The supratrochlear foramen was situated above the lateral part of the humeral trochlea, just adjacent to the middle branch of trifurcation of the anterior border of the humerus. It was ovoid in shape with the long axis transversally (6.3/3.7 mm).
Presentation of such variants contributes to increasing the anatomical data capital and might be important for diagnosis of peripheral neurovascular compression syndromes.
作者展示了一个案例，其中肱骨的主要变异出现在同一标本上：髁上突和滑车上孔。髁上突是位于肱骨内侧髁附近的肱骨前内侧表面的一个骨性隆起，可能是尺神经或正中神经以及肱动脉压迫综合征的起源，尤其是与斯特鲁瑟斯韧带相关时。
该解剖标本是在一项旨在建立当前肱骨解剖学标准和形态测量学的更大规模研究中意外发现的。对髁上突和滑车上孔进行了形态学和形态测量学分析。
髁上突位于左肱骨的前内侧表面，在内侧髁上方约5厘米处。其长度为12.4毫米，向内侧远端方向。滑车上孔位于肱骨滑车外侧部分上方，紧邻肱骨前缘分叉的中间分支。其形状为椭圆形，长轴横向（6.3/3.7毫米）。
展示此类变异有助于增加解剖学数据储备，可能对周围神经血管压迫综合征的诊断具有重要意义。
