Avulsion fractures of the pelvic apophyses are a result of repetitive strain injuries or sudden, forceful eccentric or concentric contractions of corresponding muscle groups in the leg. Using a case study approach, we present the clinical and radiological features, and management of a 14-year-old boy who presented to our hospital with an avulsion fracture of the anterior inferior iliac spine. The literature on the subject, along with the management of the condition, is reviewed and presented. A condition often treated nonoperatively, the focus of treatment is based on effective nursing and rehabilitation of the patient on an outpatient basis. Without this vital role, patients are at risk of unnecessary hospitalization that also has adverse socioeconomic effects.
