Struthers ligament

Struthers' ligament is a rare feature of human anatomy, consisting of a band of connective tissue that runs between the shaft of the upper arm bone, the humerus, and a projection at the same bone's lower end. It was discovered by John Struthers,
It is not a constant ligament, and can be acquired or congenital. Its clinical significance arises form the fact that the median nerve, passes in the space between the ligament and the humerus, and in this space the nerve may be compressed leading to supracondylar process syndrome.
