What's New Going Forward? Dual Mobility Bearings in Total Hip Replacement

Description

This presentation by Simon Jameson reviews the findings on dual mobility bearings in primary total hip replacement as documented in the 17th Annual Report. It highlights the evolution and application of dual mobility bearings, originating in the 1970s, and their role in reducing dislocation rates compared to traditional bearings, as well as concerns regarding wear and complications. Recent FDA approvals for low-wearing polyethylene reinvigorated interest in dual mobility, particularly for specific patient demographics at high risk for dislocation. The report mentions an overall dislocation rate of 2-3% within the first year, increasing to 14% in high-risk groups, with dislocation remaining the top reason for early revision surgeries. It indicates an increasing trend in the use of dual mobility from 0.35% in 2012 to 1.7% in 2019, particularly in patients with fractured neck of femur—accounting for 25% of cases. Although the use of dual mobility bearings is rising, overall revision rates and complications such as infection remain a concern, especially in high-risk patient populations. The findings suggest that while promising, dual mobility bearings require further monitoring and specialized analysis to assess long-term outcomes.
