Your natural hip joint forms what's called a ball and socket joint. With the POLAR3◊ total hip replacement, the ball portion of your joint will be replaced by the combination of a POLARSTEM◊ hip stem and an OXINIUM◊ femoral hip head. For the socket portion, the POLAR3 System uses a combination of the R3◊ cup and a highly cross-linked polyethylene plastic liner.
R3 is the primary cup used by Smith & Nephew surgeons globally. With over a decade of clinical heritage, it has been used in major markets all over the world and has been implanted in more than one million cases since its launch. In addition, it has reported results in all major orthopaedic registries, making it a trusted technology platform with proven success.
The highly cross-linked polyethylene liner, also called XLPE, works in concert with the OXNIUM hip head to make up VERILAST Hip Technology.
Hip replacement surgery is intended to relieve hip pain and improve hip function. However, implants may not produce the same feel or function as your original hip. There are potential risks with hip replacement surgery such as loosening, fracture, dislocation, wear and infection that may result in the need for additional surgery. Longevity of implants depends on many factors, such as types of activities and weight. Do not perform high impact activities such as running and jumping unless your surgeon tells you the bone has healed and these activities are acceptable. Early device failure, breakage or loosening may occur if you do not follow your surgeon's limitations on activity level. Early failure can happen if you do not guard your hip joint from overloading due to activity level, failure to control body weight, or accidents such as falls. Talk to your doctor to determine what treatment may be best for you.
