Anterior superior iliac spine (ASIS) avulsion injuries typically occur in athletes during forceful muscular contraction. The anterior superior iliac spine is the site of attachment for sartorius and tensor fascia latae muscles.

Pathology

Anterior superior iliac spine avulsion, like other pelvic avulsion injuries, is a stable fracture.

Treatment and prognosis

These can usually be treated on an outpatient basis with crutches, analgesics, and modified activity. Spontaneous recovery usually occurs within 4-to-6 weeks.

Occasionally, surgical intervention is required to remove painful fragments or to regain anatomic fixation.
