Anatomical terminology

The supracondylar process of the humerus (also known as an avian spur) is a variant bony projection on the anteromedial aspect of the upper arm bone (humerus), about 5–6 cm above the medial epicondyle. It is directed downward, forward and medially pointing to the medial epicondyle. A fibrous band, Struthers ligament, may connect this process to the medial epicondyle. This variation has a prevalence of 0.68% and is significantly more common in women than in men.
