Management of a Displaced Sciatic Buttress Fragment in an Associated Both Column Acetabulum Fracture: A Case Report.

CASE: We report the case of bilateral acetabula fractures including an associated both column (ABC) acetabulum fracture with dissociation of the sciatic buttress in a 33-year-old woman. The patient was treated with open reduction internal fixation.

CONCLUSION

The case highlights approach utilization and thoughtful sequencing of this rare fracture pattern and constellation of injuries. The displaced sciatic buttress fragment adds complexity to the typical treatment of ABC fractures regarding reduction sequence and exposure. Successful clinical and radiographic outcomes are shown at the 2-year follow-up.
