Avulsion fractures of the anterior superior iliac spine (ASIS) are rare. Cases occur predominantly in adolescent athletes when participating in competitive sports. Actions such as sudden starts and stops while running and kicking make adolescent athletes more prone to avulsion fractures. In this study, we present a 16-year-old male who had sudden onset of pain in the right groin while running a race and consequently was unable to raise his right leg. He was treated conservatively and returned to full weight bearing 3 months later. He was followed up at the orthopedic department and recovered uneventfully without residual functional impairment.
