Preoperative angiographic assessment of the superior gluteal artery in acetabular fractures requiring extensile surgical exposures.
Extensile exposures used for complex acetabular fracture reconstructive surgery often create abductor muscle flaps pedicled on the superior gluteal artery. Preoperative arteriograms were performed in eight patients who required extended iliofemoral or modified extended iliofemoral surgical approaches to assess the integrity of the superior gluteal artery. All of the patients had complex acetabular fractures, with significant displacement of the fracture into the sciatic notch. Abnormalities of the superior gluteal artery were found in three patients. One patient demonstrated a complete laceration of the superior gluteal artery, one patient a complete arterial occlusion, and one patient had a compressive entrapment of the artery at the fracture site. Preoperative angiographic evaluation of the superior gluteal artery is suggested for patients with acetabular fractures that are displaced into the sciatic notch and who will require an extensile surgical exposure creating an abductor muscle flap supplied by the superior gluteal artery.
