Mobile Bearing Hip™ Replacement

With over 250,000 hip replacement surgeries performed in the United States each year, you are certainly in good company. The high success rate associated with total hip replacement has helped millions of people return to their more active lifestyles.

twin-palm-ortho-hipIn order to help alleviate your pain and get you back to living your life, your doctor wants to ensure that the implant he or she selects for you closely matches your anatomy and allows for performance over time. Stryker’s Mobile Bearing Hip™ with X3® Advanced Bearing Technology is a mobile bearing, rather than a fixed bearing hip replacement. Mobile bearing Hip™ replacement components are designed to fit together in a unique way to allow for a more natural range of motion, more resistance to wear and greater joint stability.

An innovation in hip replacement design, the Mobile Bearing Hip™ Replacement only from Stryker features a unique polyethylene insert made with X3® Advanced Bearing Technology. Either a metal or ceramic head is locked into the insert and the insert moves within the anatomic metal shell. The Mobile Bearing Hip’s™ design allows your doctor to more closely match the implant to your anatomy and provides you with several potential advantages.

Greater Range of Motion

The Mobile Bearing Hip™ Replacement is built for more natural movement. Its anatomic cup is designed to offer stability while allowing greater freedom of movement. Test results demonstrated approximately 145° range of motion in a front-to-back sweep of the leg — a full 5% gain in range of motion when compared with fixed-bearing implants of equivalent size. Stryker’s Mobile Bearing Hip™ is designed to better accommodate your natural walking (gait) cycle of movement in range of motion. Greater range of motion may allow you to maintain your active lifestyle with fewer compromises.

Comfort and stability are important to helping you regain your activity level. The Mobile Bearing Hip™ Replacement is designed to help minimize the potential risks of hip dislocation and irritation of the muscles and tendons that support your hip.

Until now, in order to reduce the possibility of dislocation, doctors often turned to the use of metal-on-metal large head technologies for primary hip replacement. The specialized polyethylene insert of the Mobile Bearing Hip™ implant is designed to offer the potential benefits of a larger diameter head, which contributes to increased joint stability.

Its specially designed cup is also less likely to impinge on the tendon that runs from the groin toward the front of the pelvic bone (iliopsoas tendon). An impingement might result in hip stiffness, groin pain and/or a clicking sensation in the hip — signs that the pelvis may be catching the tendon when the hip flexes. Stryker’s Mobile Bearing Hip™ features an anatomic cup with an iliopsoas tendon cut-out to help prevent impingement.

Less Wear and the Potential for a Longer Lasting Implant

Constantly looking to improve orthopaedic medicine, physicians and engineers study closely the “bearing surface” of implants — where the joint comes together to carry your body weight. Stryker’s Mobile Bearing Hip™ with X3® offers wear protection on two fronts. Both its dual mobility and its X3® technology bearing surface help to create a prosthesis that is designed to resist wear and has the potential to last longer. Test results demonstrate that X3® has shown a 97% decrease in wear compared to conventional polyethylene in laboratory testing. Less wear may mean a longer life for your hip replacement.
