Stryker has received clearance from the FDA for its MDM X3 Modular Dual Mobility Mobile Bearing Hip System.

MDM X3 is a third-generation dual mobility device that allows surgeons to offer the benefits associated with Stryker’s dual mobility technology to a broader patient population, including those who may benefit from advanced fixation. Like Stryker Orthopaedics’ ADM X3, MDM X3 is designed to enhance stability and jump distance, which may increase range of motion in specific patients.

ADM X3 Mobile Bearing Hip System is Stryker’s flagship mobile bearing product and was developed to enhance joint stability. To address limitations in stability, conventional designs focus on the use of metal-on-metal large head technologies, which, based on recent studies, suggest added risk due to metal-on-metal articulation. 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 is designed to offer the benefits of a large diameter bearing without a metal-on-metal articulation.

The dual points of articulation in dual mobility constructs help accommodate multi-directional movement, which provides the potential for greater range of motion and reduced wear compared to competitive fixed implant designs, based on laboratory testing.
