Prostheses, Joint, Ankle, Tibial Component

Definition : Implantable prostheses designed to be affixed to the distal tibia bone, replacing the socket of the ankle joint. These prostheses provide a partial substitution of the ankle articulation; they typically consist of a metal (e.g., cobalt or chromium alloy) base-plate tray that is attached to the tibia and a hard plastic (e.g., medical-grade polyethylene) cup that serves as the bearing surface. Made of ceramics, polymers, or a combination of materials, the prostheses may be intended for implantation with or without bone cement. Tibial component ankle joint prostheses are used in patients who suffer from osteoarthritis or rheumatoid arthritis, as well as after trauma.
