Femoral-Joint Prosthetic Device
US Patent:
4895573, Jan 23, 1990
Filed:
Mar 23, 1988
Appl. No.:
7/172026
Inventors:
James B. Koeneman - Mesa AZ
Joseph A. Longo - Phoenix AZ
Roger H. Johnson - Phoenix AZ
Thomas M. Hansen - Phoenix AZ
Allan M. Weinstein - Paradise Valley AZ

Assignee:
Harrington Arthritis Research Center - Phoenix AZ
International Classification:
A61F 236, A61F 232
US Classification:
623 23
Abstract:
A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 15. degree. -30. degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified cancellous bone. A 3. degree. -15. degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur. In the method of the invention, the cavity which receives the prosthesis stem is formed by a rasp/broach-type tool whose surface conforms closely to that of the stem.

Abstract:
A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 18. degree. -30. degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified calcellous bone. A 3. degree. -15. degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur. In the method of the invention, the cavity which receives the prothesis stem is formed by a rasp/broach-type tool whose surface conforms closely to that of the stem.
