Definitions

  • the present invention relates to a joint prosthesis.
  • - 1 comprising a ball and a socket, surgically implantable anchoring means for the ball and the socket, and connect ⁇ ing elements by means of which the ball and the socket can 5 be fixed to their respective anchoring means.
  • ankle prostheses for example, of 10 titanium have been developed.
  • anchoring means in the form of titanium plates are used, which, in a first operation, are inserted and screwed securely to the tibia and talus.
  • a second operation is performed in which the ends of the bones are cut off, whereafter the ball and the socket are screwed securely to the anchoring means which are inte ⁇ grated with the bones. Since it is impossible to determine 20 .
  • the surgeon must, at the second operation, either have access to an assortment of different joint components to be certain to find a ball and a socket which will be correctly aligned 25 with each other in view of the positions of the anchoring means, or he must be able during the operation to work on the components of the joint prosthesis in order to achieve a proper fit. This is time consuming and often involves having to accept minor deviations from an ideal alignment.
  • the purpose of the present invention is to provide a joint prosthesis of the type described by way of introduction, which eliminates the need for working up the components or having a variety of different prosthesis components during 35 the second operation. At the same time, it is intended to provide a guite exact fit between the socket and the ball.
  • the connecting elements comprise means permitting relative lateral displacement of the ball and of the socket relative to the associated connected element, means for locking the ball and the socket into the respective connecting element after adjustment of the ball and the socket in relation to each other, and means arranged to permit vertical adjustment of the distance between at least one of the anchoring means and associated connecting element.
  • Figure l shows a partially sectioned side view of an ankle prosthesis according to the invention
  • Figure 2 shows a front view of the ankle prosthesis in Figure 1.
  • the ankle prosthesis according to the invention comprises upper and lower anchoring means in the form of a plate l and a pair of externally and internally threaded sleeves
  • the plate 1 is provided at. its lower end with a bead 3 of circular cross-section, which is disposed in a circular groove 4 in a connecting element in the form of a bridge 5, having a dovetail groove 6 extending perpendicular to the circular groove 4.
  • a slide body 8 In the dovetail groove 6, there is received a slide body 8 having the same profile as the groove 6 and integral with a plate 7.
  • the plate 7 has a depression 9, in which the ankle joint socket 10 is fixed, e.g. by adhesive.
  • the arrangement described makes the 5 socket 10 displaceable laterally relative to the anchoring plate l.
  • the connection via the bead 3 and the groove 4 makes possible a minor angular adjustment of the bridge 5 relative to the plate 1.
  • a connecting element in the form of a second bridge 12 with a dovetail groove 13 is joined to the sleeves 2 by means of four links or legs 14.
  • the links 14 are screwed securely to the bridge 12 and the sleeves 2 with the aid of upper screws 15 which are screwed into the threaded
  • stop screws e.g. socket-head screws 21, 22, which are screwed into threaded through-bores 23 and 24, respectively, to the respective dovetail groove 6 and 13, respectively.
  • the ankle prosthesis described is implanted in two opera ⁇ tions.
  • the plate l is implanted into the tibia and the sleeves 2 are implanted in the talus.
  • the plate 1 is provided with evenly spaced holes 20
  • the sleeves 2 are preferably also provided with holes or perforations (not shown).
  • the tibia is now shortened so that the cylindrical end surface 3 is exposed and it is slid into the cylindrical groove 4 in the bridge 5.
  • This connection permits com ⁇ pensation for minor angular errors when implanting the plate.
  • the bridge 5 has grooves or teeth 26 on its upper surface for integration with the bone.
  • the respective slide bodies 8 and 18 for the ball and socket, respectively are slipped into their dovetail grooves and are adjusted laterally relative to each other and locked with the associated screws 21, 22. If required, in addition to the vertical adjustment possibility provided by the links, additional vertical adjustment can be achieved by varying the thickness of the upper bridge 5 and/or the slide body 8.
  • Suitable modi ⁇ fication of the anchoring means e.g. the plate 1 and the sleeves 2, can enable the joint to be used for elbows, shoulders, etc.
  • the material in all of the joint components, except for the socket, is titanium.
  • the ball is suitably made of Titanium 6 AL 4Vm which is tempered and possibly ion- -nitrated or otherwise surface-hardened. All of the other titanium components are made of titanium GRADE 1.
  • the socket is made of polyethylene, and can be porous and impregnated with HEALON.

Abstract

Prothèse de cheville à composants en titane, comprenant une rotule (19) et un logement (10), fixée sur des moyens d'ancrage (1, 2) destinés à être implantés chirurgicalement dans le tibia et l'astragale. Grâce à des éléments de connexion intermédiaires (5, 12) dotés de rainures en queue d'aronde (6, 13) disposées perpendiculairement l'une par rapport à l'autre, il est possible d'opérer un réglage latéral entre la rotule et le logement de rotule.
