The supine position is used for anterior approaches as well as insertion of IS screws.
Place the patient in the supine position on a radiolucent table.
A urinary catheter should be inserted prior to beginning the procedure.
Prior to starting the procedure fluoroscopic AP, inlet and outlet x-rays should be obtained to ensure adequate visualization.
Prior to draping, ensure that the C-arm is able to obtain the necessary images without being obstructed by the table.
The legs should be accessible for possible reduction maneuvers, but not necessarily prepped and draped. A pillow to flex the hip can help to relax the neurovascular structures and iliopsoas muscle if desired for anterior pelvic approach. All pressure points should be padded.
