Pediatrics Case 1 Background

Avulsion Fracture of the Anterior Superior Iliac Spine

Groin injuries comprise 2-5% of all sports-related injuries. Differential diagnosis of groin pain in athletes includes adductor strain or tear, osteitis pubis, sports hernia, iliopsoas bursitis, stress fracture, nerve compression, snapping hip syndrome, and avulsion fracture.

Pelvic avulsion fractures most commonly occur in young sprinters, hurdlers, soccer players, and gymnasts, in the following locations:

  • ischial tuberosity
  • anterior superior iliac spine (ASIS)
  • anterior inferior iliac spine (AIIS)
