Definitions
- the object of the invention relates to a disc prosthesis for cervical vertebrae intended to be substituted for the fibro-cartilaginous disc ensuring the connection between the cervical vertebrae of the spinal column.
- an intervertebral disc can undergo alterations such as compaction, deformation, displacement or wear and more generally a degeneration associated with mechanical stresses which are applied to it and lead to anatomical and functional destruction of the disc and the vertebral segment.
- This disc alteration modifies the mechanical behavior of the disc and leads to a reduction in the height of the intersomatic space, which leads to a disturbance of the articular functional unit. This results in instability inducing, in particular, an arthritis reaction, a source of pain and of osteophytic process.
- a herniated disc requiring the removal of the cervical disc. It has therefore been proposed to replace the defective disc with an artificial disc of which various types of embodiment have been envisaged.
- a disc prosthesis for lumbar vertebrae comprising first and second fixation plates for neighboring vertebrae, made of a metallic material such as titanium. Between the plates is interposed a hinge ball comprising a first insert mounted on one of the plates and composed of a spherical cap cooperating with a spherical cup of a second insert mounted on the other plate.
- the inserts are made of a biocompatible ceramic material having improved tribological characteristics, in particular as regards its resistance to wear.
- the object of the present invention therefore aims to remedy the drawbacks of the prior art by proposing a disc prosthesis for cervical vertebrae designed to have a relatively long lifespan while being practically insensitive to the phenomena of wear and breakage, while being adapted to allow physiological mobility between the two instrumented cervical vertebrae.
- the prosthesis according to the invention for cervical vertebrae comprises: - a first and a second plate intended to be fixed to neighboring cervical vertebrae, - and articulation means interposed between the two plates placed in superimposed position .
- the articulation means comprise: - means authorizing flexion-extension movements in the sagittal plane according to an angular movement limited by stop means in flexion-extension, - means authorizing inflection movements lateral in a plane perpendicular to the sagittal plane according to an angular movement limited by means of abutment in lateral inflection, - means authorizing relative rotational movements between the first and second plates according to an angular movement limited by means of abutment in relative rotation , - means of assembly with the first and second plates so as to constitute a one-piece prosthesis.
- the articulation means comprise: - a partially spherical profile bore establishing itself inside a chamber arranged in a plate, - and a profile bearing complementary to the bore arranged in the other plate and mounted in the bore to be locked in this last.
- the means authorizing flexion-extension movements comprise an axis extending in the sagittal plane by projecting on either side of the span, in clearances arranged in the second plate in s' opening in the spherical bore.
- the clearances have a determined diameter making it possible to define the angular movement of the relative rotational movements between the first and second plates.
- the relative rotation stop means consist of a female geometric shape cooperating with a complementary male geometric shape, one of the geometric shapes being arranged on the first plate while the other geometric shape is produced on the second plate.
- the lateral inflection stop means consist of the profile of the plates coming into contact with one another.
- the bearing surface is arranged in a first insert mounted on the first plate and produced in the form of a stud and in that the bore is arranged in a second insert mounted on the second plate and produced in the form of a Ring.
- the inserts are made of ceramic or metal.

- the plates 2 and 3 have an anatomical profile making it possible to adapt to the intervertebral space.
- the first plate 2 has in the sagittal plane S, a convex profile while in this same sagittal plane S, the second plate 3 has a substantially planar profile. Furthermore, as can be seen more precisely from FIG. 4, the second plate 3 has in the frontal plane F, a convex profile while the first plate 2 has a plane profile.
- the external faces 2 ⁇ , 3 ⁇ of the plates 2 and 3 are equipped with bone anchoring elements
- each plate 2, 3 has a general trapezoidal shape with a posterior edge respectively 2a, 3a extending opposite and parallel to the frontal plane F and to a front edge 2b, 3b respectively.
- the front edge 2b, 3b of each plate 2, 3 is connected to the respective rear edges 2a, 3a by means of two lateral edges 2c, 3c divergent from the front edge 2b, 3b.
- each lateral edge 2c, 3c is connected on the one hand to the anterior edge 2b, 3b respectively by a connection leave 2d, 3d and on the other hand to the rear edge 2a, 3a via a leave 2nd, 3rd connection.
- articulation means 7 are interposed between the two plates 2, 3 placed in superimposed position.
- the articulation means 7 comprise: - means authorizing flexion-extension movements in the sagittal plane S according to an angular movement limited by means of abutment in flexion-extension 9, - means authorizing lateral inflection movements in a frontal plane F perpendicular to the sagittal plane S according to an angular movement limited by lateral inflection stop means 12, - means allowing relative rotational movements between the first 2 and second 3 plates according to a movement angular limited by means of stop in relative rotation, - assembly means 17 with the first 2 and the second 3 plates so as to constitute a one-piece prosthesis.
- the articulation means 7 make it possible to control in the frontal plane F, in the sagittal plane S and in the transverse plane T the relative movements between the first 2 and second 3 plates according to movements limited corresponding to the natural physiological mobility between two cervical vertebrae.
- the articulation means 7 allow the plates to have movements according to the various combinations of these different planes.
- the articulation means 7 are constituted in particular by a bore 20 of partially spherical profile, being established inside a chamber 21 arranged in the example illustrated in the second plate 3. This bore is intended to cooperate with a profile span 23 complementary to the bore 20.
- the profile span 23 partially spherical is mounted in the bore 20 so as to be locked together.
- the bearing surface 23 is arranged in a first insert 25 mounted on the internal face of the first plate 2 and produced in the form of a stud.
- this insert 25 comprises a base of circular section partially engaged in a housing opening on the internal face of the plate 2. This base is extended by the bearing surface 23 of partially spherical profile.
- the bore 20 is arranged in a second insert 26 mounted in the chamber 21 of the second plate 3 and produced in the form of a ring.
- the inserts 25, 26 are made of metal or ceramic.
- the bore 20 and the bearing surface 23 constitute means authorizing the flexion-extension movements in the sagittal plane S, the lateral inflection movements in the frontal plane F, and the relative rotational movements in the transverse plane T.
- the means assembly 17 between the first and second plates 2, 3 are produced by the insertion of the bearing surface 23 of spherical profile in the bore 20.
- the articulation means 7 comprise an axis 31 passing right through the bearing surface 23 extending in the sagittal plane S.
- the axis 31 protrudes on either side of the bearing surface 23 being engaged in recesses 32 arranged in the ring 26 by opening in the bore 20.
- the two recesses 32 which extend diametrically opposite have a height, that is to say a measurement in the sagittal plane S adapted to allow the flexion-extension movements in the sagittal plane of the plate 2 relative to the plate 3.
- the stop means 9 in flexion-extension consist of the profile of the plates 2, 3 coming into contact with one of the 'other.
- the recesses 32 have a determined diameter, that is to say a measurement in the transverse plane T determined to define the angular movement of the relative rotational movements between the plates 2, 3.
- the clearances 32 limit the rotation of the axis 31 along the transverse plane T.
- the clearances 32 thus constitute the stop means in relative rotation between the plates 2, 3.
- the axis 31 allows lateral inflection movements in the frontal plane F perpendicular to the sagittal plane S, of the plate 2 relative to the plate 3.
- FIG. 6 to 9 illustrate a second alternative embodiment of a prosthesis 1 according to the invention.
- This prosthesis includes articulation means 7 identical to those described above and for this purpose have the same references.
- the bore 20 is part of a ring 38 having a slot 39 allowing the mounting of a bearing surface 23 by elastic deformation.

- the female geometric shape is produced on the insert 25 mounted integral with the first plate 2 while the complementary male geometric shape 41 extends from the bottom of the chamber 21 of the second plate 3.
- These female 40 and male 41 geometric shapes are said to be complementary in the sense that they allow flexion-extension movements in the sagittal plane S, lateral inflection movements in the frontal plane F, and relative rotational movements between the first and second plates.
- These geometric shapes 40 and 41 are adapted to constitute stop means in relative rotation between the plates 2 and 3 for a limited angular movement.
- the bending-extension stop means consist of the internal faces
- the lateral inflection abutment means 12 are constituted by the internal faces 2 2 and 3 2 of the plates 2, 3, respectively, as is clear from FIG. 9.
