Case report of combined iliac crest and ASIS apophysis avulsion fracture in an adolescent footballer.

Pelvic apophyseal avulsion fractures are uncommon injuries that typically occur in adolescents during sporting activities. Iliac crest (IC) apophyseal injuries represent a small percentage avulsion fracture around the pelvis with a reported incidence rate of 5%. We present a rare case of an adolescent boy who sustained a combined anterior superior iliac spine/iliac crest apophyseal avulsion fracture while playing football. With painful limited hip range of movement and inability to weight-bear, plain film and computed tomography scan illustrated a displaced fracture which was managed conservatively with an excellent clinical and radiological outcome. A review of apophyseal fractures around the pelvis, including incidence, mechanism of injury and treatment options regarding surgical versus conservative treatment, are discussed.
