Iliac Apophysitis in a High School Football Player: A Case Report.

Iliac crest avulsion injuries are rare and frequently misdiagnosed in adolescents. We report a case of a 16-year-old boy who presented with iliac apophysitis following a noncontact injury during a football game. The diagnosis was confirmed with radiography. The patient was treated conservatively with activity modification, limited weight bearing, and physical therapy, resulting in full recovery. This case highlights the importance of considering rare apophyseal injuries and obtaining appropriate imaging in adolescent athletes.
