New Data Reinforces the Proven Safety and Effectiveness of the BIRMINGHAM HIP Resurfacing System80-percent of US surgeons choose the BHR hip as it outperforms all other metal-on-metal resurfacing devices
MEMPHIS, Tenn., May 3 /PRNewswire-FirstCall/ — Recent new data(1) presented at this year’s American Academy of Orthopaedic Surgeons (AAOS) annual meeting reinforces the BIRMINGHAM HIP™ Resurfacing (BHR) System as a safe and effective hip resurfacing device. 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.This week, the Hospital for Special Surgery (HSS) in New York City will be holding a medical education course titled “Total Hip: Replacement and Resurfacing” on May 7 and 8 for leading hip surgery specialists from across the U.S. Chairing the course will be Edwin Su, MD, of the Hospital for Special Surgery, and the teaching faculty will include pioneering British surgeon Derek McMinn, MD, inventor of the BHR hip. During a press conference and Q&A webcast on Thursday, May 6, at 3 p.m. US EDT, 8 p.m. GMT, Joseph M. DeVivo, president of Smith & Nephew Orthopaedics (NYSE: SNN, LSE: SN), the maker of the BHR Hip, will be joined by Dr. Su and Mr. McMinn, as well as Scott Marwin, MD, an orthopedic surgeon with New York University’s Hospital for Joint Diseases. The panel will review current data confirming the safety and effectiveness of hip resurfacing and the BHR Hip. Smith & Nephew Orthopaedics will host the call, and additional details are at the bottom of this release. 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. These sources include:
“The BHR Hip’s outcomes are remarkable when compared to other resurfacing devices,” said Dr. Marwin. “The depth and consistency of the data collected globally shows the BHR Hip is truly different.”“For the right patients in my practice, hip resurfacing has proven to be an excellent choice,” said Dr. Su. “They have extremely high levels of satisfaction after returning to their regular lifestyle.” 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. The BHR Hip has a unique metallurgy heritage which goes back more than 30 years and includes a first-generation metal-on-metal resurfacing process which contributes to long-term survivorship of BHR Hip recipients. 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. Of particular importance during hip resurfacing surgery is the correct positioning of the acetabular cup, or hip socket. When this component is not properly aligned, studies show that metal wear can accelerate and resurfacing devices can fail before their time. 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. “Just like the lubricating barrier in a healthy hip, there is a natural fluid layer between the femoral head and the cup that the two metal surfaces glide across during physical activity,” said Mr. McMinn. “If the surgeon malpositions the acetabular cup causing edge loading, the lubrication is lost. It’s equivalent to running a car engine without lubrication oil. High wear will occur, resulting in premature failure. Overall, it is a combination of the metal composition, the design and the quality of the surgical technique that makes the BHR Hip the safest resurfacing implant on the market.” “The bottom line is that the BHR Hip is not like other metal-on-metal hip implants,” said DeVivo. “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.” To participate in the press conference webcast being held on May 6, please use the dial-in numbers below.
