-Arthrography of the hip prosthesis-

Arthrography of hip arthroplasties is a safe, easy-to-perform procedure. It is mainly indicated when infection of the arthroplasty is suspected: the contrast agent fills bone defects that may be present between normal bone and the prosthesis and reaspiration of injected fluids may lead to bacteriological diagnosis. Another indication for arthrography of hip arthroplasties is unexplained painful hip prosthesis.
