Magnetic Resonance Imaging (MRI) can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Early detection can result in timely revision surgery, decreasing the risk for further tissue damage and pain. Researchers reviewed the MRI images of 70 patients who ultimately underwent revision surgery for a failed MoM implant. The images were assessed for the presence of tissue damage, swelling and other characteristics.
