Answers from Edward R. Laskowski, M.D. Most avulsion fractures heal very well without surgical intervention. An avulsion fracture occurs when a small chunk of bone attached to a tendon or ligament gets pulled away from the main part of the bone. The hip, elbow and ankle are the most common locations for avulsion fractures in the young athlete. Treatment typically includes resting and icing the affected area, followed by controlled exercises that help restore range of motion, improve muscle strength and promote bone healing.
