A recent study has found that a modern type of hip implant can dramatically cut dislocation risks after certain hip replacement surgeries. The dual-mobility implant, which features a small ball rotating within a larger ball, has been shown to reduce dislocation rates by 70% compared to traditional implants.

How it Works

The dual-mobility implant works by creating a larger diameter ball that must travel further to escape the socket, reducing the risk of dislocation. Researchers in Europe conducted a study involving 1,600 people aged 65 or over, randomly assigning them to receive either a standard implant or a dual-mobility implant. The results showed that dislocation rates were 1.3% with the dual-mobility cup, compared to 4.2% with traditional hip replacement.

The study also found that the overall risk of surgical complications was lower with the new cup, although there were no differences in rates of implant infections, deaths, or quality of life during the first year. The researchers noted that the reduction in complications could offset the higher upfront cost of the dual-mobility implant.

Implications

The findings of this study have significant implications for the treatment of hip replacement patients. With the dual-mobility implant, patients may be able to reduce their risk of dislocation and improve their overall quality of life. The study’s authors also noted that the change to dual-mobility implants could be implemented immediately, as surgeons are already familiar with both implant types.
