Point-of-care ultrasound detection of anterior inferior iliac spine avulsion fracture in an adolescent: A case report.

PURPOSE

This study presents a rare case of avulsion fracture of the anterior inferior iliac spine, typically occurring in adolescents engaged in physical activities. The purpose of this study is to emphasize the diagnostic challenges and conservative treatment options available for this condition.

METHOD

We describe the case of a 14-year-old healthy adolescent who suffered from an avulsion fracture following pelvic trauma after participating in a short-distance sprint. Initial physical examination and X-ray imaging were inconclusive, showing no apparent fractures. Due to parental refusal of a Computerized Tomography (CT) scan by concerns over the potential risks associated with radiation exposure, a diagnostic ultrasound was performed, which confirmed the presence of an avulsion fracture at the anterior inferior iliac spine.

RESULTS

The ultrasound findings led to a conservative treatment approach, involving rest, and unloading of the affected limb. Follow-up assessments indicated significant pain relief within four weeks and enabled the resumption of partial physical activity after six months.

CONCLUSION

This case highlights the utility of ultrasound as an effective alternative diagnostic tool in situations where CT scans are not permissible. Additionally, it demonstrates that conservative management can be successful in treating avulsion fractures of the anterior inferior iliac spine in adolescents, leading to satisfactory recovery and return to activity.
