Conditions
Avulsion fracture
An avulsion fracture is an injury to the bone. Basically, it is a fracture that occurs at the location where a tendon or ligament attaches to the bone. This tendon or the ligament pulls off a piece of the bone along with it instead of ligament tear. An avulsion fracture can occur anywhere in the body, most commonly in the knee joint.
Causes
