Dual mobility in primary total hip arthroplasty: current concepts

[摘要] Total hip arthroplasty (THA) is one of the most successful surgical procedures – reducing pain and providing functional improvement to enhance patients’ quality of life. As healthcare continues to evolve and life expectancy rises, the demand for THA will grow, with the number of THAs performed in the United States projected to increase by 174% by 2030 compared to 2005.1 However, THA is not without risk. Total hip arthroplasty instability is a disabling condition and remains the most common indication for revision THA in the United States; accounting for 22.5% of revisions.1 It is particularly prevalent in high-risk cohorts (such as those with neuromuscular disease, obesity or cognitive dysfunction) where revision rates have reached up to 14%.2 The economic ramifications of this are staggering – with the cost of revision often exceeding 50,000 US dollars prior to consideration of additional costs such as post-acute hospital care.
