Abstract:
1. A transcutaneous prosthesis which comprises: a first component shaped for implantation into a bone; a second component adapted for location between the bone and the skin, the second component having an outer surface having one or more surface treatments for stimulation of fibroblastic cell proliferation and attachment of epithelial cells, the surface treatments being porous, being micro-pitted, and/or being coated with an external coating of a material selected from hydrated calcium phosphate, adhesion promoting proteins and alumina oxide ceramics; and a third component adapted for location to extend directly from the skin surface in use, the third component having an outer surface thereof, wherein the outer surface of the third component comprises a non-stick material whereby the surface has a surface energy that is lower than a surface energy of the first and second components and which deters bacterial adhesion, wherein, in use, a transition from the second component to the third component is essentially at the surface of the skin and the third component extends from the skin surface, such that the non-stick outer surface of the third component is adjacent to the surface treated outer surface of the second component when the first component is implanted in a bone.
