Supine AP pelvic radiographs are routinely used for planning hip arthroplasties

The most crucial aspects of proper radiograph acquisition for this projection are described, with special focus on patient and equipment positioning. We focus on supine rather than standing AP pelvic radiographs given the practical considerations relevant to performing THA -- supine radiographs can be compared directly to pelvic radiographs captured intra-operatively or at early follow-up when the patient may have restricted weight bearing.
