Stryker’s Mobile Bearing Acetabular System Intended to Reduce Hip Replacement Surgery Risks

The ADM X3 Mobile Bearing Acetabular System, which was released by Stryker Corp. at the annual meeting of the American Academy of Orthopaedic Surgeons, is a technology for hip replacement surgery designed to minimize risks, the firm said.

The Mobile Bearing Hip system is possible due to Stryker Orthopaedics’ X3 Advanced Bearing Technology, which is designed to increase the longevity of the implant. Laboratory tests have shown a 97 percent reduction in volumetric wear compared to conventional polyethylene, the company said.

ADM’s anatomic design also has the potential to increase mobility and reduce groin pain, according to Stryker. 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, a key cause of post-operative groin pain, the firm said.

“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, based in Mahwah, N.J.
