Definitions
- the invention relates to an implant system comprising a concave spherical cap-shaped socket part and a corresponding convex spherical cap-shaped joint part, wherein the hinge part rests in the socket part, according to the feature combination according to claim 1.
- a component arrangement for a prosthesis in particular a cervical disc prosthesis, which consists of two basic components with attached sliding surfaces.
- H are the basic components preferably made of polyether ether ketone and the sliding surfaces, for example, a Co-Cr alloy.
- polyether-ether ketone has a modulus of elasticity similar to that of cortical bone, this material is particularly well suited for bonding surfaces of the prosthesis to be implanted and the bone exposed for good elasticity characteristics.
- the material In order to achieve an increase of the bone to the PEEK material, however, the material must be subjected to a special treatment.
- the Co-Cr alloy used in the sliding surfaces was used due to the good sliding properties with low abrasion of the material.
- This cervical intervertebral disc prosthesis initially consists of a first and a second plate intended to be attached to adjacent cervical vertebrae.
- a ball joint is provided, which is arranged between the two plates, which are mounted one above the other, wherein the ball joint consists of a spherical cap which cooperates with a spherical cap.
- the plates can be advantageously carried out in titanium, the Contact surface with the vortex plates of the vertebrae, for example, with hydroxyapatite or titanium coated with surface effect, in order to improve the anchoring between the prosthesis and the adjacent bones.
- the ball joint can in turn have a different combination of materials.
- the spherical cap may be made of zirconia, while the corresponding spherical cap may be made of alumina.
- Ceramic has a decisive disadvantage.
- Prostheses which are formed, for example, as a ball joint or include such, can not be economically produced so that the spherical cap and the spherical cap play with each other without play with the whole surface (this can not be achieved even with metal implants).
- Each ball joint is ultimately condemned to having either a point pad or a ring pad due to this game.
- point support may have such a effect on a ceramic material that premature wear of the prosthesis occurs with the addition of tensile forces, resulting in breakage or displacement of the prosthesis.
- an implant system which comprises a concave spherical cup-shaped socket part and a corresponding convex spherical cap-shaped hinge part, wherein the hinge part rests in the socket part, according to the feature combination according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.
- At least three support elements are arranged on the surface of the joint part or on the surface of the socket part, which describe a ball triangle or a spherical polygon.
- the described spherical cap-shaped socket and joint parts may on the one hand be components of a hip, knee, elbow, jump or wrist.
- the spherical cap-shaped elements may represent parts of an implant system for intervertebral disc prostheses in the spinal region.
- the advantage of the support elements on the surface of the socket or joint part is, on the one hand, that the entire load acting on the implant system can be distributed over at least three points, instead of one point as usual.
- the hinge part can not have any translation within the customary play.
- the three support elements are arranged on the surface of the joint or socket part on the convex or concave curvature that they a spherical triangle - also called a ball triangle - (in three support elements) or a spherical polygon - also called ball quadrangle - (more than three Limit support elements). This means that at no time all support elements lie on a circular arc.
- the support elements are arranged around a central point of the spherical cap-shaped joint part or pan part spherically by 120 °. Whereby these angle specifications are not subject to any tolerance (for technical reasons the angle specifications do not have to be complied with), since the at least three existing support elements always rest on the surface of the socket part or of the joint part.
- the support elements are designed according to the invention as punctual elevations of the surface of the spherical cap-shaped hinge part or the spherical cap-shaped pan part.
- curved surface of the joint part or the cup part so individual elements are attached which form the punctual elevations of the support elements.
- the elements may be dome-shaped or pyramid-shaped shapes which, due to their bearing on the surface of the joint part or of the socket part (depending on the part on which the support elements are mounted) represent support elements in the form of punctiform elevations.
- the curved surfaces of the joint and socket part described in the embodiments represent only an exemplary form of the individual parts of the implant system.
- the surfaces can also be designed plan or be provided with bevels.
- the support elements are designed as a flat elevations relative to the surface of the spherical cap-shaped joint part or pan part.
- elements in the form of, for example, small prisms or cylinders are mounted on the surface of the joint or pan part, which give a support element in the form of a flat elevation due to their support on the surface of the joint part or socket part.
- the support elements are not only formed on a uniformly curved socket or joint part, but the respective surfaces of the socket or joint part in the support elements form a level or recess or one, based on the entire Gelenkteil- or pan part surface , have a smaller radius of curvature.
- the entire implant system described consists of a ceramic material.
- a metal or plastic implant titanium and PEEK as a plastic material may be mentioned.
- material combinations are conceivable, according to which the joint part, for example, titanium and the joint part u. a. can be made of PEEK.
- the support elements are again preferably made of ceramic.
- such ceramic support elements are pressed into the titanium or PEEK plates of the joint or socket part.
- the support elements have a lower roughness than the remaining surface of the socket or joint part, so that the support elements are smoother than the remaining surface of the respective component of the implant system.
- the support elements are surface-treated.
- the elements are polished because this is a relatively simple production step. This has the advantage that not the entire part on which the support elements are arranged must be polished, but only the support elements are processed, which come into contact with the corresponding implant system part.
- the support elements are coated with a different material, so through the material coating
- a smoother or more resistant surface can be designed.
- the implant system described with the support elements according to the invention can preferably be used in connection with prostheses in the spinal area. So a use as an intervertebral disc prosthesis is conceivable.
- the socket part described in such a case for example, the acetabulum and the joint part is the joint bone located on the thigh bone.
- FIG. 1 shows a representation of an implant system according to the invention with supporting elements as punctiform elevations
- FIG. 2 shows the support element resting on the socket part
- FIG. 3 representation of an implant system according to the invention with introduced into the joint part recesses and support elements in the form of flat elevations and
- Fig. 4 is a further illustration of an inventive
- Implant system with introduced into the joint part Recesses and support elements in the form of flat elevations.
- the implant system consists of a joint part 1 and the socket part 2. It can be seen that the joint part 2 is formed in the form of a convex spherical cap member and the socket part 2 in the form of a corresponding concave spherical cap shaped element.
- FIG. 1 are located on the hinge part 1 three support elements 3, which are arranged around the central point of the curved hinge part spherical at 120 ° to each other. Furthermore, it is clear that the support elements 3 describe a ball triangle. For imaginary connecting lines, the supporting elements 3 enclose a spherical triangle. However, if more than 3 points of support are used, they will include a sphere polygon.
- the advantage in the construction of an implant system with three support elements is that regardless of the distances of the support elements to each other and the maintenance of tolerances, the support elements always rest in the spherical cap.
- FIG. 2 The interaction between the support elements 3 and the contacting socket part 2 is shown in FIG. 2 shown.
- the section shows a arranged on the hinge part 1 support element 3, which contacts the concave-shaped surface of the socket part 2. Due to the design of the support element 3 as a spherical cap, a point contact takes place.
- FIG. 3 shows a further exemplary embodiment of the implant system according to the invention.
- the three support elements 3 are on the surface of the joint part 1, but not directly on a uniformly convex surface but on a recess 4.
- This recess 4 has a concave curvature in the middle of each of the support elements 3 are mounted.
- the concave curvatures serve to provide a draft-free construction which is particularly important in the manufacture of a ceramic implant system.
- support elements 3 in the form of a flat survey. That is, the support elements 3 have a basic shape of a truncated cone, which is known to be flattened at its top. This flattening is completely in contact with the surface of the socket part 2 in a composite implant system.
