Abstract
A prosthesis with an integral proximal spacer is described. The prosthesis has a base element with a textured surface to aid in adhesion to bone cement. The integral spacer has a generally tripod shape. A top circumferential portion at least partially surrounds the proximal end of the prosthesis, and three legs extend distally along the length of the prosthesis. Also disclosed is the process for making the prosthesis and spacer, which preferably involves injection molding of PMMA.
