2011 R&D 100 Winner
More than 193,000 total hip replacements are performed each year in the United States. While most are successful, some complications from the surgery remain.
The ADM X3 Mobile Bearing Hip Acetabular System, developed by Stryker Orthopaedics, Mahwah, N.J., is designed to minimize the most common complication in total hip replacement, dislocation. This occurs when the implant becomes displaced or misaligned.
Unlike conventional fixed-bearing hip replacement systems with one fixed point of articulation, the ADM X3's dual mobility system has two points of articulation that help accommodate multi-directional movement and provide a greater range of motion than fixed implant designs. A larger diameter femoral head provides improved resistance to dislocation.
The patented X3 Advanced Bearing Technology, designed to increase the longevity of the implant, has been shown in laboratory tests to provide a 97% reduction in volumetric wear compared to conventional polyethylene. The anatomic design features a tendon cutout that matches the patient's anatomy to help avoid impingement and possible groin pain.
