Reassuring early serum metal ion levels with a specific modular dual mobility system

In this series of a specific modular DM system, the early mildly elevated cobalt levels in four patients all subsequently normalized. Chromium was mildly elevated in four patients through year two. While these findings are reassuring in the short term as mildly elevated chromium (<2 μg/L) has not been associated with clinical toxicity, additional follow-up is needed to establish the long-term safety and efficacy of this specific modular DM implant.
