Abstract

ABSTRACT

Radiography is the mainstay of the imaging evaluation of the prosthetic hip, but arthrography, aspiration, scintigraphy, sonography, computed tomography, and magnetic resonance imaging all have roles in the evaluation of the painful prosthesis. This article reviews the appearance of normal hip arthroplasty as well as the appearances of potential complications.

KEYWORDS
