ABSTRACT:
This invention relates to a skeletal implant designed to provide a structure which bone can fill so as to biologically anchor the implant in position. A series of cutting edges are aligned on at least part of the surface and directed in a direction of relative movement between implant and bone. Bone removed by these edges is urged into a series of interconnecting spaces beneath the surface. Preferably a porous surface and the cutting edges are provided by perforated microcontoured sheet material. The three dimensional porosity formed by the perforations and contours results in bone debris impacted into the voids particularly at the time of implantation which will subsequently become integral with surrounding bone.
