Apophyseal Avulsion Fracture
A pelvic apophyseal avulsion fracture occurs with a sudden contraction of the muscle that inserts on the apophysis. This injury usually occurs in activities such as sprinting, hurdling, kicking, jumping, and doing splits.
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.
