Active people of all ages, rejoice! On the heels of the New York Times‘ article about growing concerns associated with metal-on-metal hip implants, Stryker Orthopaedics has announced the release of the ADM X3 Mobile Bearing Acetabular System, a “next-generation technology for hip replacement surgery designed to minimize the risks associated with total hip replacement.” The ADM X3 device is based on Stryker’s proprietary X3 Advanced Bearing Technology, that features a polyethylene bearing material that has shown, according to the company, “excellent wear characteristics” while preserving mechanical strength of ortho implants.
More about the new shiny hip implant:
While total hip replacement is one of the most successful surgical procedures performed today, dislocation remains one of the top reported complications. To address dislocation, conventional designs focus on the use of metal-on-metal large head technologies which based on recent studies suggest added risk due to metal ion release. Combining an evolution in design with the only anatomic dual mobility acetabular system and its patented X3 Advanced Bearing Technology, Stryker Orthopaedics Mobile Bearing Hip addresses dislocation without the risk of metal ion release.
“By developing an implant that addresses adverse outcomes associated with hip replacement surgery, we are not only helping surgeons to treat their patients more successfully, but we are also striving to reduce global healthcare costs by minimizing surgical complications,” said Bill Huffnagle, Vice President and General Manager of Hip Reconstruction at Stryker Orthopaedics.
This Mobile Bearing Hip system is made possible due to Stryker Orthopaedics’ patented X3 Advanced Bearing Technology which is designed to increase the longevity of the implant. Laboratory tests have shown a 97% reduction in volumetric wear compared to conventional polyethylene. ADM’s anatomic design also has the potential to increase mobility and reduce groin pain. Its dual points of articulation help accommodate multi-directional movement, which provide greater range of motion than fixed implant designs based on laboratory testing. In addition, the anatomic cup design has an iliopsoas tendon cut-out aimed at reducing iliopsoas tendon impingement(6), a key cause of post-operative groin pain.
