  • Method of constructing prosthetic implant with wrapped porous surface
    Patent number: 5018285
    Abstract: A method of constructing a prosthetic implant including a porous pad separate from the stem of the implant and in which the pad is wrapped around the stem for attachment thereto. The pad is first precontoured into a preliminary shape and is then wrapped about the stem in a second and final shape corresponding to the shape of the stem portion about which it is wrapped and subsequently secured.
    Type: Grant
    Filed: January 16, 1990
    Date of Patent: May 28, 1991
    Assignee: Zimmer, Inc.
    Inventors: Arden R. Zolman, Phillip J. Andersen, Steven T. Bayne
  • Prosthetic implant with wrapped porous surface
    Patent number: 5013324
    Abstract: A prosthetic implant including a porous pad separate from the stem of the implant and in which the pad is adapted to be wrapped around the stem for attachment thereto. The pad is first precontoured into a preliminary shape and is then wrapped about the stem in a second and final shape corresponding to the shape of the stem portion about which it is wrapped and subsequently secured.

  • Prosthesis with enhanced surface finish
    Patent number: 4795472
    Abstract: An orthopaedic prosthesis for implantation with a bone cement composition, the prosthesis including a polymer coating and a textured surface underneath at least a portion of the polymer coating. The textured surface, which is visible to the eye without magnification, beneath the polymer coating enhances or increases the surface shear and tensile strength of the prosthesis.

  • Method for constructing a surgical implant
    Patent number: 4660755
    Abstract: A method for constructing a surgical implant provides a porous layer that is metallurgically bonded to a substrate. An electrode passes current through the porous layer and through the substrate while also controlling the compaction of the porous layer relative to the substrate.
