Definitions

  • ABSTRACT A total knee or elbow joint prosthesis having opposing condyle and plateau replacing members for attachment respectively to the upper and lower arm or leg bones, the members having respectively convex and concave spherical mating surfaces.
  • a knee or elbow jointprosthesis comprises an artificial upper bone member and a mating lower bone member, the upper bone member having a pair of spaced condyle portions joined by an intercondyloidal segment. Each condyle portion is formed with a spherically curved downwardly facing convex surface.
  • the lower bone member has a pair of similarly spaced plateau portions joined by an interplateau segment, each plateau portion being formed with a spherically curved upwardly facing concave surface.
  • the radius of each spherical condyle surface is no greater than that of the corresponding spherical plateau surface, and may with advantage be a little less to make for easy articulation in an anterior-posterior plane.
  • FIG. 1 is an elevational view of a knee joint in its anterior aspect. incorporating the prosthesis of the present invention
  • FIG. 2 is a side view, lateral aspect of the knee joint in FIG. I;
  • FIG. 3 is a section taken in the direction of arrows 3-3 of FIG. 1;
  • FIG. 4 is a section taken in the direction of arrows 44 of FIG. 2;
  • FIGS. 5 and 6 are respectively top and bottom views of a plateau member constructed according to the present invention for attachment to the tibia;
  • FIG. 7 is a perspective of a condyle member according to the present invention for attachment to the femur.
  • a knee joint showing the major upper and lower bones, the femur 10, the tibia 11 and the fibula 12, has been illustrated.
  • Various ligaments and tendons which interconnect these bones and regulate, restrict and determine the flexing or articulated movement of the tibia with respect to the femur have not been shown. Hinged movement naturally occurs between the condyle portions 13 of the femur and between the plateau portions 14 of the tibia.
  • the prosthesis of the present invention shall be surgically implanted in substitution for diseased mating portions of the femoral condyles and the tibial plateaus.
  • the prosthesis therefore includes a femoral condyloidal member 15 and a mating tibial plateau member 16 which are uniquely constructed in accordance with the present invention.
  • Member 15 has a pair of spaced condyloidal portions 17 and 18 which are integrally joined by an intercondyloidal segment 19.
  • the proximal posterior surface of each segment 17 and 18 may be provided with a recess 20, 21 and the proximal anterior portions thereof may similarly be provided with recesses 22, 23 therein.
  • Each of the condyloidal portions 17 and 18 include tapered pins 24, 25 which will be received within openings made by the surgeon in the mating portions of the femur.
  • the member can be joined to the femur (after diseased natural condyles have been removed) and secured thereto in a manner which is known.
  • Member 15 may be cast integrally of a metal compatible for the purpose, such as a cobalt-chromiumbase alloy or a stainless steel. Alternatively member 15 may be manufactured of separately produced and surfaced condyle portions which are then welded to a plate which provides the intercondyloidal segment 19. Member 16 also may be metallic, but is preferably is formed mainly of a suitable high density organic polymer. Other materials of construction also may be used for either or both members, such as pyrolytic or vitreous carbon, or a ceramic material.
  • each condyloidal portion 17 and 18 is uniquely formed as a section of the surface of a sphere. That is to say, in both anterior-posterior and in lateral-medial directions, the curvature of each surface 17a, 18a will conform to that of a sphere having a predetermined diameter, which in the present embodiment is approximately the straight line distance between the anterioral and posterioral extremities of each portion 17 and 18 as shown in FIG. 2.
  • the surfaces 17a, being spherical lend themselves to being given a surface finish of extremely high quality by known machining and finishing techniques.
  • the member 16 as shown in FIGS. 1 to 4 attached to a tibia comprises a pair of spaced plateau portions 27, 28 joined by an integral interplateau segment 29. Each plateau portion is provided with a downwardly projecting pin 30, 31.
  • the segment 29 and the plateau portions 27 28 have serrations 32 on their under surfaces which together with the pins 30 and 31 permit the member 16 to be firmly anchored by a suitable cement to the upper end of the tibia after the latter has been suitably prepared surgically.
  • each of the plateau portions 27 and 28 has an upwardly facing concave spherical surface 27a and 28a which may have an identical center of curvature to that of each downwardly convex spherical surface 17a, 18a of the member or advantageously, the radius of the concave surface may be made somewhat greater than that of the convex surface to permit smooth rotation in the anterior-posterior plane with limited lateral-medial motion and axial rotation.
  • a metal wire 34 is preferably imbedded in the member 16 in known relationship with respect to the geometrical dimensions of such member. This is done to provide an X-ray opaque reference member, since the member 16 is of insufficient density to be readily detected in X-ray photographs of the prosthetic knee joint.
  • each spherically curved condyle portion and plateau portion has an anterioral-posterioral dimension substantially greater than its lateral-medial dimension. In the particular embodiment, such anterioral-posterioral dimension is substantially twice the lateral-medial dimension.
  • a joint prosthesis suitable for knee or elbow comprising an upper member and a mating lower member, the upper member having a pair of spaced condyle portions joined by an intercondyloidal segment, each condyle portion being formed with a spherically curved downwardly facing convex surface, and the lower member having a pair of spaced plateau portions joined by an interplateau segment, each plateau portion being formed with a spherically curved upwardly facing concave surface engageable with the corresponding convex surface, the radius of each spherical condyle surface being no greater than that of the corresponding spherical plateau surface, said upper and lower members including means for attachment to a bone structure and providing for substantial articulation of such bone members in a single plane, and said intercondyloidal segment and interplateau segment being substantially narrower than the respective condyle portions and plateau portions thereby providing intercondyloidal and interplateau apertures for receiving cruciate ligaments connecting upper and lower bone structures to which the prosthesis is
  • a joint prosthesis according to claim 1 in which the upper member is metallic and the lower bone member is made mainly of an organic polymer.
  • a joint prosthesis according to claim 1 in which the radius of each spherical condyle surface is less than the radius of curvature of each mating spherical plateau surface.
  • a joint prosthesis according to claim 1 in whic each spherically curved condyle portion and plateau portion has a front-to-back dimension that is substantially greater than its side-to-side dimension.
