POCUS of the right ilium demonstrated a hyperechoic structure anterolaterally displaced towards the ASIS, suggesting an ASIS avulsion fracture. A 14-year-old male patient visited our emergency department for groin pain he experienced during a game of baseball.

We reported herein a pediatric case of anterior superior iliac spine (ASIS) avulsion fracture detected by POCUS. X-ray is commonly used to diagnose PAF, but the use of point-of-care ultrasound (POCUS) for this purpose in pediatric emergency departments has yet to be published.
