ABSTRACT:
A spacer for use in the centering of the far end portion of the stem of a prosthetic implant is molded of a synthetic polymeric material compatible with the cement employed to affix the prosthetic implant within the natural bone and includes a post for coupling the spacer with the stem, a flanged spacer portion for extending longitudinally and radially beyond the stem to engage the natural bone for centering the stem, and a reinforcing core extending longitudinally into the post and into the flanged spacer portion to reinforce the spacer against stresses to which the spacer is subjected, especially at a location between the post and the flanged spacer portion of the spacer, during implant and during subsequent curing of the cement.
