Traumatic posterior acetabular defects reconstructed with iliac crest autograft. A report of two cases

In two cases of posterior wall acetabular fracture, the fracture fragment was too comminuted to be fixed per primam. A full-thickness iliac crest autograft was used as initial reconstruction in these two cases. Although the reconstruction was not anatomic, one of the two patients is functioning with only minimum symptoms at five years. Incorporation of the autograft has been documented in both cases. Although the procedure may not accurately reproduce the anatomy of the hip joint, it will appropriately supplement viable acetabular bone structure.
