Abstract
The total implant is constructed of a prosthesis shank, a U-shaped plastic insert which envelops the proximal region of the shank, a deformable sheet metal jacket about the plastic insert and a pair of wedges which are driven into a space between the sides of the prosthesis shank and the sheet metal jacket in order to expand the jacket against the bone during implantation. A guide sleeve is also disposed at the distal end of the shank to slidably receive and guide the distal end of the shank.
