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.
