Laminar skin-bone fixation transcutaneous implant and method for use thereof
First Claim
1. A laminar skin-bone fixation transcutaneous implant adapted for implantation in a residual limb of an amputee comprising, in combination:
- a biocompatible bone implant post having a first segment adapted for implantation in a bone within said residual limb;
a transcutaneous segment attached to each layer of said implant; and
, a third segment adapted for attachment to a prosthesis for said amputee; and
, at least one biocompatible substantially flexible porous layer adapted for cellular ingrowth attached to adjacent layers and to said transcutaneous segment;
wherein said at least one biocompatible substantially flexible porous layer is adapted for stable sealable ingrowth by skin cells.

Abstract
A laminar skin-bone fixation transcutaneous implant adapted for implantation in a residual limb of an amputee comprising a biocompatible bone implant post having a first segment adapted for bone implantation, a transcutaneous segment attached to one or more biocompatible porous layers adapted for vascularization and stable sealable ingrowth by skin cells, and a third segment adapted for adapted for attachment to a prosthesis. The implant may include an uppermost biocompatible non-porous elastomer layer having a multiplicity of perforations. Methods for use of the implant and an article of manufacture for its packaging are also taught.
