Findings in a pelvic apophyseal avulsion fracture include tenderness at the apophysis, swelling, pain with stretching the involved muscle, and weakness and pain with active contraction of the involved muscle.


Radiographs show the fracture.  Treatment includes rest and protected weight bearing. Ice application and analgesic medications can help relieve pain. A progressive rehab program should also help recovery.
