What is an avulsion fracture?

An avulsion fracture occurs when a small section of bone becomes detached at a site where a ligament or tendon attaches. This often happens due to a sudden, forceful pull on the ligament or tendon, which can lead to the pulling action being strong enough to disrupt the bony attachment. The fracture typically results in a piece of bone being pulled away along with the soft tissue structure.

This type of injury is particularly common in sports and activities that involve rapid changes in movement or excessive strain on joints, where the force exerted on the tendon or ligament is significant enough to overcome the strength of the bony interface. Understanding this type of fracture is crucial for athletic trainers as it directly impacts treatment protocols and rehabilitation processes. Proper identification and management of an avulsion fracture are essential to ensure proper healing and prevent future injuries.
