Struthers' ligament and associated median nerve variations in a cadaveric specimen.

A Ligament of Struthers has been identified and studied in a cadaveric arm. Its relationships to a rudimentary supracondylar process, the pronator teres muscle, the median nerve, and the medial epicondyle of the humerus are described. Compared to an extensively studied series of normals, the ligament in this case was associated with abnormally proximal branching of the median nerve, a finding which is surgically significant and not addressed in the literature to date.
