The final choice is whether to have the femoral side made as a single unit or opt for a modular version.
Ceramic on epoly.
Ceramic epoxy coating is a unique abrasion resistant coating that protects by binding ceramic particles to a resin system thus creating an encapsulating ceramic shell.
There are two main techniques used in hip replacement fixation.
Ceramic epoxy coating provides.
This lip serves to lower the risk of dislocation.
A randomized trial of ceramic on ceramic bearing versus ceramic on crossfire polyethylene bearing in total hip arthroplasty.
From 2007 to 2014 the use of ceramic on poly bearing surfaces increased from 11 1 of cases in 2007 to 50 8 of cases in 2014.
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 ceramic cup can not incorporate the lip that is a standard part of a plastic cup liner.
Ceramic devices by contrast appear to cause far less inflammation and few if any pseudotumors.
Each ceramic particle is resin coated and becomes tightly packed in the cured film.
This appears true whether the device is all ceramic ceramic and metal or ceramic and plastic.
While it may seem reasonable to suggest that these benefits translate to longer problem free use we can really only assume that at this stage.
