Anterior Superior Iliac Spine (ASIS) Avulsion Fracture

Video Transcription

Video Summary

A 15-year-old male experienced left hip pain during a varsity football game, with a radiograph revealing an avulsion fracture of the anterior superior iliac spine. Such fractures, resulting from forceful muscle contractions, are common in young athletes due to strong muscles against weak, unfused growth plates. Key tendon attachment sites in the pelvis help identify fracture locations: most commonly, the ischial tuberosity for the hamstrings, followed by the anterior inferior and superior iliac spines. Lesser common locations include the iliac crest and pubic symphysis, which correlate with various muscle attachments. Recognizing these patterns assists in accurate diagnosis.
