An ischial apophysis avulsion

An ischial apophysis avulsion is an injury to the ischial tuberosity (sitting bone) in a place where the hamstring or adductor magnus (groin) attaches to the bone. In an avulsion of the ischial tuberosity, sudden contraction of the hamstrings or adductor magnus anterior pulls off a piece of the sitting bone. This causes pain and swelling and usually occurs in young athletes between 13 and 25 years.
