Bilateral anterior inferior iliac spine avulsion in an adolescent soccer player: a typical imitator of malignant bone lesions.

Avulsion fractures are usually diagnosed easily in acutely presented cases. The diagnosis becomes definite if clinical and radiological follow up reflect the fracture's healing phase. A 13-year-old soccer player with bilateral anterior inferior iliac spine (AIIS) avulsion, who had been examined in other institutions with a prediagnosis of malignancy, is reported. Clinically, such cases display the importance of medical management of athletic injuries by specially trained physicians. From the perspective of preventive medicine, the high incidence of AIIS injuries during soccer games, and the bilateral nature of the damage mandate a review of the training programs and shooting techniques for adolescent players.
