Around the world, different resurfacings have been introduced in an effort to compete with the BIRMINGHAM HIP
◊. To date, no competitive resurfacing has matched the performance demonstrated clinically by the BIRMINGHAM HIP
◊ . In Australia, where a variety of resurfacing devices have been available and evaluated in their implant registry, the BIRMINGHAM HIP
◊ is not just the most successful, but also the most popular by far.
In the clinical study provided to the FDA, the BIRMINGHAM HIP◊ showed a 98% success rate at 5 years(3). Less than 2% needed to be revised for any reason. Most other devices haven’t been around long enough to have results published. On the two longest competitors, published results show a much lower success rate, of 92%(4) and 95%(5) at shorter follow up times. Because these are resurfacing components, the patients were probably able to get a total hip replacement after failure, but the results appear to be significantly inferior to those of the BIRMINGHAM HIP◊.
