Modern Dual Mobility Implants in Total Hip Arthroplasty: Stability, Survival, and Ion Safety Evaluation

Le résumé fourni par la source

» Dual mobility cup (DMC) implants reduce dislocation rates in both primary and revision total hip arthroplasty (THA), particularly in high-risk patients with neuromuscular disorders, cognitive impairment, or obesity. » The dual articulation mechanism enhances joint stability by increasing jump distance and the head-to-neck ratio, without compromising range of motion. » Incorporation of highly cross-linked polyethylene and vitamin E-infused liners improves wear resistance, supporting broader use in younger, more active patients. » Long-term survivorship of modern DMCs is comparable or superior to fixed-bearing implants, with a lower revision burden and durable fixation when appropriately selected and implanted. » Systemic metal ion levels remain low in well-functioning modular DMCs, though continued monitoring is recommended in younger patients and those with reproductive potential.
