Metal Ceramic Metal Hip Replacement

There are ceramic on metal ceramic on ceramic and ceramic on polyethylene versions.
Metal ceramic metal hip replacement. Metal on metal or metal on polyethylene. Ceramic hip replacement. In addition the surfaces are much harder than the traditional artificial plastic hip socket making it less susceptible to wearing out. Ceramic on ceramic and metal on metal bearing surfaces are often employed for total hip replacement because of their resistance to wear.
In fact the only thing harder than aluminium oxide is diamond. The type of ceramic used in hip replacements is an oxide of a metal oxide ceramics and specifically alumina ceramic and zirconia ceramic. The ball is made of ceramic and the socket has a metal lining. In case your imagining that your hip will be made of some sort of pottery let me reassure you.
Like other total hip replacement systems the device comes in two parts but now for the first time the femoral component will made from ceramic and the pelvis side from metal. Ceramic hip replacement systems made of durable ceramic oxides of metal offer both advantages and disadvantages over hip replacement systems made of metal or polyethylene among the advantages of ceramic hip replacements are their durability and that they don t release metal debris into the body which can occur with metallic artificial hips. If for some reason i would need a hip replacement my single biggest concern would be wear particles. Brittleness is a major concern for ceramic and ion release is a drawback for metal.
However they have some limits. Ceramic on metal hip bearings show less wear friction than all metal hip bearings no stripe wear and a 10 fold reduction in metal ion levels were found using the combination. Ceramic is one of the best materials that can be used in a hip replacement but when paired with a metal socket it quickly falls to the back of the pack. An orthopaedic surgeon should determine which hip implant will offer the most benefit and least risk for each patient.
These metal surfaces are highly polished and smooth. Metal on metal implants use a similar design to standard hip replacements but the surfaces of both the ball and the socket are made of metal. Ceramic hip implants are among the newer types of prostheses being used for hip replacement offering greater resistance to damage and smooth movement of the joint. Why a new system.
While these are durable they can be vulnerable to fracture and breaking under big stresses.
