an injury to the bone in the area where a tendon or ligament attaches to the skeleton
A small portion of bone, with ligament or tendon attached, is pulled away from the main bone segment.
Avulsion fractures occur at the attachment of ligaments or large tendons to bones, when a fragment of bone becomes detached with injury.
the force of the break has allowed a tendon or ligament to tear off a piece of bone from where it's normally attached.
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament due to the application forces external to the body (such as a fall or pull) or at the tendon due to a muscular contraction that is stronger than the forces holding the bone together. Generally muscular avulsion is prevented due to the neurological limitations placed on muscular contractions.
