Stryker MDM X3 Hip Replacement System Gets US Green Light
by Gene Ostrovskyon Feb 11, 2011 • 9:54 am
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.

I am having my 3 year old BHR revised and, although my cobalt and chromium levels are not out of range (cobalt <1.0 ug/L, chromium .7 mcg/L), I have had symptoms of metal poisoning over the last 3 years. In doing the research on the Stryker MDM which I am receiving in 8 days, I am reading it has a cobat/chromium liner, which has me a bit worried. Does there exist any THR prosthetic that doesn't contain cobalt or chromium (or any other metal that has a history of metal poisoning)?
