Definitions

  • the invention relates to a set for creating a metatarsophalangeal joint.
  • the set comprises at least one cap-shaped, convex outer contours, to be placed on the metatarsus stump of the great toe and the shape of two ball sections imitated implant with an integrally formed on the base edge, in a circular segment of 30 ° to 180 ° rotating shield.
  • the set has as a basic element a kind of cap prosthesis, which is movable like a joint ball with respect to the Grundphalanx.
  • Decisive feature for the long-term stability is the mentioned Sign. This works together with the sesamoids and the flexor tendon in such a way that the sesame legs do not come into contact with the processed bone. The sesame legs and flexor tendon are instead guided on the surface of the implant.
  • the metatarsus must be processed before fitting the cap prosthesis with suitable tools, such as a tiller, which would result in the risk of ankylosis, a sign would not be provided.
  • suitable tools such as a tiller, which would result in the risk of ankylosis, a sign would not be provided.
  • the bone should be worked so that the shield is flush with the bone, so no step from the shield to the bone is formed. As a result, the emergence of high forces in the area of the shield is avoided on the bone.
  • the basic element of the kit according to the invention is therefore a hemiprosthesis.
  • the cap prosthesis runs against the natural concavity in the Grundphalanx. Since the implant preferably consists of a biocompatible metal, so metal runs against bone / cartilage.
  • the implant has a stalk protruding from the pole region to the concave open side and to be placed in the metatarsus stump. Accordingly, in this case, the metatarsus must be drilled out or milled out so that the pedicle can reach into the bone.
  • the bottom of the implant has a three-dimensional open-mesh spatial network structure on its surface. Bone trabeculae grow into and through these and secure the seat of the cap prosthesis on the metatarsus stump. As a result, a high long-term stability is achieved.
  • the same purpose is served by a measure of a further development of the implant, in which the surface of the stem is at least partially provided with a three-dimensional open-meshed spatial network structure. Bone trabecules also grow into and through them, thus ensuring stable secondary fixation.
  • the stem has an oval cross-section. This training serves the rotational stability of the cap prosthesis.
  • the set additionally comprises a phalanx stick which can be inserted into the basic phalanx and a insert which can be connected to it as a sliding partner for the cap-shaped implant with a concavity which is open towards the metatarsus stump and adapted to the shape of the implant. From this set can therefore be created a complete denture, in which the cap-shaped implant can move relative to an artificial sliding partner.
  • This sliding partner may be made of polyethylene, for example. It is also a sliding into consideration, which consists of a composite ceramic (EP 0502082).
  • the phalanx stem on the other hand, preferably consists of a body-compatible metal.
  • the surface of the phalanx stalk also at least partially has a three-dimensional open-mesh spatial network structure into and through which Bone trapezoid can grow and thus secures the seat of the stem in the Grundphalanx.
  • FIG. 1 shows a schematic side view of the foot skeleton
  • FIG. 3 is a view similar to FIG. 1, but in the region of the joint in section,
  • FIG. 4 is a view similar to FIG. 3 with the implant as a total denture
  • FIG. 5 is a view similar to FIG. 4, wherein a bending movement is shown schematically
  • Fig. 6 is a view of the toggle joint from below
  • FIG. 7 shows a detail enlargement from FIG. 5.
  • the cap-shaped implant 2 sits on the tip of the machined metatarsus. Like a joint ball, it is formed with a pole curve of two spherical sections and works together with the natural concavity of the basic phalanx 9. Formed on the base edge is a circular segment-like shield 4. The metatarsus has been machined so that the bone is flush with the shield 4. 2 shows an enlarged sectional view of the cap-shaped implant 2. It has in this case a protruding from the pole region to the concave open side out into the metatarsus stump to be set stem. The bottom of the implant 2 has a three-dimensional open-meshed spatial network structure 7 on its surface.
  • the surface of the stem is partially provided with a three-dimensional open-mesh spatial network structure 8. Bony trapezes grow into and through structures 7 and 8 to provide stable secondary fixation.
  • the shield 4 At the base edge 3 of the shield 4 is formed. In the present case, it represents an extension of the cap-shaped implant 2. The function of the shield is explained below.
  • FIG. 3 illustrates the position of the implant 2 in the area of the great toe joint due to the partially cut representation in the area of the joint.
  • FIG. 4 shows a similar view to FIG. 3.
  • a complete prosthesis has been created from the set in the present case.
  • the insert 11 serves as a sliding partner for the cap-shaped implant 2 in the exemplary embodiment.
  • the insert 11 has a concavity 12 modeled on the natural concavity of the basic phalanx 9.
  • FIG. 5 shows the complete prosthesis created from the set with the cap-shaped implant 2, the phalanx stem 10 and the insert 11.
  • the cap-shaped implant 2 cooperates with the sesamoidal bone 14, that is, they roll on the implant 2.
  • the shield 4 prevents the contact of the sesame legs with the Metatarsus stump 1 and thus an ankylosis. Also shown is the flexor tendon 15.

  • FIG. 7 is an enlarged view of FIG. 5 in the area of the joint. Clearly visible are the three-dimensional open-mesh spatial network structures 7, 8 and 13 and the shape-adapted concavity 12 of the insert 11 in the phalanx stem 10. The flush transition between the shield 4 and the metatarsus 1 is clear.
