n a high density plastic socket.
             Unfortunately with all implants some of the pieces will break off causing
             an immune system reaction that destroys underlying joint tissue, and this
             can loosen the implant. Researchers tried to eliminate this problem by
             creating a newer highly crossed-linked polyethylene plastic coating that in
             theory is supposed to be even more durable and stronger. Researchers say
             that implants made from this new material may be best suited for patients
             The next material that is used today is metal-on- metal implants.
             These are very similar to the metal on plastic but are said to last longer.
             There is no research that says this is harmful. This type of implant is
             not recommended for patients with kidney problems, or women at childbearing
             age. Another approach being used is ceramic. This approach is fairly new
             and quickly gaining popularity. The cups only come in one shape, this
             requires surgeon to place cup perfectly to avoid dislocation. In other
             rare cases the bearings can become loose causing hip to fracture.
             Although we can't determine all the information yet, with more research
             we should be able to find out more information on how the cements held up.
             It takes some years to observe the wear on hip implant.
             The last approach is the cementless method which is attached by
             using a porous coating. Using a porous coating will allow the joint to
             adhere to the artificial joint. Post-surgery the bone should grow around
             the porous coating. The bone will then start filling in the space between
             There are three different approaches while performing total hip
             replacement. These approaches are the antero-lateral approach, posterior-
             lateral approach, and last the anterior approach. Alth
