Avulsion fracture
Avulsion Fracture
An avulsion fracture (/əˈvʌlʃən ˈfrækʧər/) is a type of bone fracture that occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur in any bone in the body but is most commonly seen in areas where a tendon or ligament, which are attached to the bone, are injured. The force of the injury causes the tendon or ligament to pull off a piece of the bone, resulting in an avulsion fracture.
Etymology
The term "avulsion" comes from the Latin avulsio, meaning "to tear off", while "fracture" comes from the Latin fractus, meaning "broken".
