Avulsion Fractures

Avulsion fractures are injuries to a bone where a tendon or ligament is stretched under pressure to the point where it pulls away from the bone. This pressure causes pieces of the bone to be pulled along with the tendon or ligament, causing a fracture. An avulsion fracture can occur anywhere in the body. A child is more vulnerable to have an avulsion fracture than an adult because the growth plate in a child’s skeleton is weaker than its associated tendon. As a result, tendons or ligaments in close proximity to the growth plate can pull hard enough that the growth plate fractures. Occasionally this type of injury involves the pelvis.

Treatment

In most cases, avulsion fractures can be treated non-surgically with ice and rest. Exceptions to this are avulsion fractures that caused severe tendon or ligament retraction or tendon damage in addition to the fracture. In such cases, surgery may be necessary to reattach the bone fragments to the fracture base. An experienced doctor, such as Dr. Louis, should be consulted to determine the best treatment for the patient’s specific avulsion fracture.
