Hip replacement surgery is a complicated procedure recommended to patients with hip joint injury or osteoarthritis of the hip.
Ceramic on ceramic hip replacement no restrictions.
Ceramic hip replacements are a safer choice because no metallic ions are released into the body.
Predicting wear of ceramic ceramic hip prosthesis using finite element method for different radial clearances.
Ceramic materials offer the potential for a longer lasting hip replacement conventional hip replacement systems use an insert made of plastic and a head made of metal.
This lip serves to lower the risk of dislocation.
Disadvantages of ceramic hip replacement systems include the potential for the material to fracture the expense and noise.
A ceramic cup can not incorporate the lip that is a standard part of a plastic cup liner.
There have been numerous studies released that tout the lack of issues within all ceramic hip replacement devices.
The standard rule of no bending and no twisting is not universal for all hip replacements because it depends on the incision.
Tribology materials surfaces interfaces.
Ceramic on ceramic hip replacements fulfill this need providing a longer lasting implant using stronger materials than cobalt chrome and polyethylene.
If the incision goes through the back of the hip then the precautions will include no bending over past 90 degrees no pivoting on the feet no crossing legs avoid stepping backwards and keep your toes pointed forward while walking.
These ceramic based materials have demonstrated significantly lower wear than a metal on metal hip solution because of the durability of ceramics versus traditional metal hip replacements.
They do not have any biological adverse effects or allergic responses for example.
Ceramic hip replacement disadvantages.
This artificial joint prosthesis helps reduce pain and improve function.
Ceramic on ceramic seems to be the golden child for hip replacement devices for the fast few years.
Therefore a ceramic on poly replacement has the advantage of the lip and a ceramic on ceramic has the advantage of being tougher and permitting the use of a larger femoral head.
A fractured hip may necessitate a ceramic hip replacement.
Over time these components may wear as the parts move back and forth with normal joint use.
