CT of hip prosthesis: New techniques and new paradigms.

Patients with hip pain after joint replacement are first assessed by analyzing the clinical presentation and conventional radiography findings. When this first step is inconclusive, various different imaging techniques can be used to identify the anomalies. Based on our experience, computed tomography (CT) is the cornerstone for diagnosing the main prosthesis-related complications. In this article, we describe the different CT techniques used for this kind of investigation and provide indications for each technique.
