Deforming implant-bone interface

摘要

A prosthesis can have a wall portion that deforms to conform to a surface. The deformation of the wall can be plastic (i.e. permanent) or elastic (i.e. able to return to the pre-deformed configuration). The surface can be an anatomical surface.

主权项

1. A prosthesis for placement in an anatomy, comprising:
an interior wall having an interior wall outer surface and an interior wall inner surface; an exterior wall having an exterior wall outer surface and an exterior wall inner surface, wherein at least a portion of the interior wall inner surface faces at least a portion of the exterior wall inner surface; a connecting wall connecting the interior wall and the exterior wall, wherein the connecting wall is rigid relative to at least the exterior wall, wherein:
the interior wall is spaced apart from the exterior wall to define a void between the interior wall inner surface and the exterior wall inner surface;the interior wall is rigid relative to the exterior wall;the exterior wall is configured to deform into the void when forced against a non-smooth anatomical surface, forming a deformed exterior wall, such that the exterior wall outer surface of the deformed exterior wall comprises a non-smooth surface; and a strengthening material operable to be placed within the void defined by the interior wall and the deformed exterior wall.
