An Update on the Use of Metal-on-Metal Hip Implants

    Insights on a European report addressing hip resurfacing and total hip arthroplasty from Dr. Catherine Van Der Straeten and Dr. Luigi Zagra.

    Catherine Van Der Straeten, MD, from Ghent University Hospital, Ghent, Belgium, and Luigi Zagra, MD, from Istituto Ortopedico Galeazzi IRCCS, Milan, Italy, recently participated in the development of a report by the Scientific Committee on Emerging and Newly Identified Health Risks on the use of metal-on-metal (MoM) implants in hip resurfacing and total hip arthroplasty for the European Commission.

    The committee was asked to:

    • Determine the short-, medium-, and long-term local and systemic health effects caused by metal particles, metal ions, and metallo-organic compounds resulting from the implanted medical device and, if possible, to provide indications on limit values for the metals in any forms
    • Advise on the predictive value of metal ions in body fluids, clinical strategies, and other aspects needed to ensure the safety of implanted patients. Criteria that should inform the medical decision with respect to the implanted patient should be identified where possible.
    • Identify criteria regarding the safety and safe use of MoM implants used in arthroplasty, paying special attention to design and patient groups
    • Identify, where relevant, needs for further research

    We caught up with Dr. Van Der Straeten and Dr. Zagra at the recent World Arthroplasty Congress in Paris and asked them to discuss the findings of the committee, the implications for practice, and the research that still needs to be done on MoM implants.
