Case report highlights metallosis following dual mobility implant use in total hip arthroplasty, suggesting caution.
Case A patient that underwent dual mobility liner placement presented at follow up with clinical history and imaging findings indicative of metallosis. This phenomenon with dual mobility implants is not well reported in the literature. Conclusion Although dual mobility implants allow for increased stability of the acetabular component, the benefits conferred should be weighed against the potential complications. Ensuring proper cup placement and adequate screw fixation can potentially mitigate the risk of metallosis in these cases.
