How Useful is MRI in Evaluating ALTR ?

Biologic failures of hip replacement have emerged as an increasing threat to the longevity of the prosthesis. While wear of modern day bearings has been greatly reduced with the advent of cross linked polyethylene, local reaction to metal particles either from the bearing itself or to any of the modular tapers appears to be on the rise. Monitoring of these reactions by the use of plain radiographs or serum markers appears to be insufficient to gauge the gravity of the response.Over the past decade, the use of magnetic resonance imaging (MR) techniques has emerged as the superior noninvasive instrument to assess the extent of soft tissue reaction around hip implants.
