Recent new data presented at American Academy of Orthopaedic Surgeons (AAOS) annual meeting reinforced the the safety and efficacy of hip resurfacing device Birmingham Hip Resurfacing (BHR) System.
The multi-site study, performed by orthopedic surgeons practicing at nine Canadian academic centers, showed that three years after surgery, 99.91% of their 3,400 hip resurfacing patients experienced no implant failure due to metal wear debris. The BHR Hip was the most used resurfacing device in this study.
The new study recently presented at the AAOS meeting aligns with previously released BHR Hip data from other prestigious sources and further addresses the metal wear debris concerns raised about metal-on-metal hip implants. The BHR Hip’s track record for longevity remains unchallenged in the literature, as well.
Reportedly, to explain the patient advantages seen consistently in the literature, surgeons indicate the key differences between the BHR Hip and other resurfacing devices are its metal composition, its design geometry and its surgical instrumentation.
Additionally, the BHR Hip’s design geometry replicates the natural hip’s ability to pull the body’s own joint fluids into the ball and socket interface, which is believed to be another source of its best-in-class performance. Surgeons believe that the instrument used to implant the BHR Hip is simpler and more accurate than other devices’ instruments, and may contribute to its success.
Joseph DeVivo, president of Smith & Nephew Orthopaedics and the maker of the BHR Hip, said: “The bottom line is that the BHR Hip is not like other metal-on-metal hip implants. Not only does it have the longest track record of any resurfacing device, but the most esteemed medical literature shows it outlasts other implants. It’s in a class all its own it’s safe and effective, and is the best choice for active patients.”
