Avulsion fractures of the pelvis are usually observed in skeletally immature patients, involved in sports. Sprint running and sudden accelerating and decelerating activities are the most common mechanism for these fractures. We present an adult patient diagnosed with avulsion fracture of the anterior inferior iliac spine, who experienced a nonunion after conservative treatment. The nonunion was treated surgically, 11 months after the fracture. The patient was not allowed to put any weight on the affected extremity and to extend the hip for the first two months. As of the third month, the patient started hip extension and weight bearing gradually with crutches. The patient was free of symptoms six months after the operation and radiographs showed complete healing of the fracture.
