Digital Subtraction Arthrography of the Prosthetic Hip

Digital subtraction techniques are easily adapted to the evaluation of loosening in total hip prostheses, allowing real time review of injection dynamics and data manipulation after the study. We have successfully used both standard radiographic and digital imaging techniques in the evaluation of 15 prosthetic hip joints. The digital results are comparable to and often better than those of standard radiographic techniques for the evaluation of loosening in total hip prostheses.
