Lateral and high-angle oblique radiographs of the pelvis aid in diagnosing pelvic discontinuity after total hip arthroplasty.

Diagnosis of a pelvic discontinuity before revision total hip arthroplasty is critical for adequate preoperative planning. The lateral view of the pelvis or high-angle oblique views can aid in visualizing the posterior column when hip hardware obscures the view on standard anteroposterior and Judet views of the pelvis. These views are easy to obtain and can provide valuable information when planning revision total hip arthroplasty.
