The medial antebrachial cutaneous nerve and the medial brachial cutaneous nerve were dissected in twenty fresh cadaver extremities. These nerves have a variable number of cutaneous branches ranging from four to twelve, with an average of eight. Branches always originated medially in both nerves and ran in an anterolateral direction. In all the medial antebrachial cutaneous nerves, there were three to five terminal branches directly overlying the medial epicondyle and supplying the skin over the olecranon. The course of this nerve is predictable relative to the basilic vein and the medial epicondyle. There was a ninety percent incidence of communication between the medial brachial cutaneous nerve and the intercostobrachial cutaneous nerve. The standard incision used for surgery of the ulnar nerve at the elbow will cut the terminal branches of the medial antebrachial cutaneous nerve one hundred percent of the time, and the terminal branches of the medial brachial cutaneous nerve eighty percent of the time, if they are not identified. A posterior approach for transposition of the ulnar nerve would avoid damage to these nerves.
在20个新鲜尸体上肢中解剖了臂内侧皮神经和前臂内侧皮神经。这些神经的皮支数量不一，从4支到12支不等，平均为8支。两支神经的分支均起始于内侧，并沿前外侧走行。在所有前臂内侧皮神经中，有3至5支终末支直接位于内上髁上方，并供应鹰嘴上方的皮肤。相对于贵要静脉和内上髁，该神经的走行是可预测的。臂内侧皮神经与肋间臂神经之间的交通发生率为90%。如果不加以识别，用于肘部尺神经手术的标准切口将100%切断前臂内侧皮神经的终末支，80%切断臂内侧皮神经的终末支。尺神经转位的后路手术可避免损伤这些神经。
