Bilateral anterior inferior iliac spine avulsion fractures


Medicine & Science in Sports & Exercise: February 1996 - Volume 28 - Issue 2 - p 161-164
Clinical Studies: Case Study

A case of bilateral groin pain of sudden onset in a 14-yr-old boy is presented. The patient reported sudden onset of pain in both inguinal regions during a 100-m dash. He presented a week later to the clinic where physical examination revealed a shuffling gait, bilateral hip flexion contractures, limited active and passive hip extension, and bilateral weakness of hip flexion and knee extension. Plain radiographs of the pelvis revealed avulsion fragments minimally displaced from both anterior inferior iliac spines (AIIS). Pain relief in the acute phase was achieved by limiting ambulation until weight bearing was painless. The patient was treated conservatively and returned to full speed running in 10 wk. Only one case of bilateral AIIS avulsion fractures has previously been reported. AIIS avulsion fractures that are not widely displaced may be treated conservatively. Following a careful program of rehabilitation, full functional recovery following AIIS avulsion fractures may be achieved in 4-6 wk.
