Traumatic unilateral avulsion of the anterior superior and inferior iliac spines with anterior dislocation of the hip: a case report.
A sixteen-year-old boy involved in a high-speed motor vehicle accident sustained an anterior hip dislocation and avulsion of the anterior ilium extending from the anterior superior iliac spine to the anterior inferior iliac spine. The hip was emergently reduced, and further imaging was obtained to evaluate the bony injury. Computed tomography confirmed the presence of a large displaced bony fragment representing avulsion of the anterior superior and inferior iliac spines and a smaller fragment from the reflected head of the rectus femoris. The patient underwent open reduction and internal fixation of the ilium two days after the initial injury. Postoperatively, he was allowed to bear weight as tolerated with crutches but to avoid active hip flexion. He went on to an uneventful recovery, and at last report (approximately six months after injury), he had returned to full activity. An extensive review of the literature failed to show a similar injury of ipsilateral avulsion of the anterior superior and inferior iliac spines and reflected head of the rectus femoris.
