Smith & Nephew reports trial data of BHR implant

13 February 2012

Smith & Nephew has announced the results of a new study conducted at The McMinn Centre in Birmingham, UK, evaluating the company's Birmingham Hip Resurfacing (BHR) system.

The BHR implant closely matches the size of a patient's natural femoral head (hip ball), provides greater stability in the new joint and decreases the chance of dislocation of the implant after surgery.

The study, carried out at the request of the FDA, included 258 males and 142 females with an average age of 53.2 years that were implanted either unilaterally or bilaterally with the BHR implant.

The ten-year BHR data reported that the Oswestry Modified Harris Hip Score (OMHHS) averaged 92.5 points, demonstrating outstanding long-term clinical implant function.

The study demonstrated that according to the Kaplan-Meier analysis, the BHR implant survival rate was found to be 95.9%, and radiographic success rate was 99.7% as observed by independent radiographic review.

The study found that ten years after the BHR procedure, 99% of the subjects were either satisfied or extremely satisfied.

Smith & Nephew Global Hip Franchise senior vice president John Soto said, "Not only does the BHR Hip offer all the advantages of hip resurfacing, including bone-conservation, greater range of motion and decreased risk of dislocation, but it does so while maintaining implant survivorship rates that are on par with, or in some patient populations even better than, traditional total hip replacement, which has long been considered the most successful orthopaedic surgical procedure for relieving chronic pain."

"The fact is that the BHR Hip is not like other metal-on-metal hip implants. It really is in a class all its own - it's safe and effective, and is the best choice for the right patient," Soto added.

The Birmingham Hip Resurfacing system was designed using knowledge gained from first generation metal-on-metal total hips and a thorough understanding of hip resurfacing principles.
