Dr. Peterson is the first surgeon in the region to use the latest technological advancement in total hip replacement; The Dual Mobility MDM hip replacement from Stryker. This incorporates the use of two balls instead of one. An inner ball made of ceramic or metal, and an outer X3 highly crosslinked polethylene ball. This unique bearing has the advantage of greatly increased stability compared with conventional hip replacement. A recent study that reviewed the current literature showed the dislocation rate to be only 0.1% with dual mobility hips versus 2-7% for traditional hip replacement. (MA Mont ’12) The wear rate is also significantly reduced making this a very attractive implant for younger active patients. Note in the video below how both femoral heads move independently of each other and allow greater range of motion than could be accomplished with just one.
