- FIG. 13 is a top view, illustrating an intervertebral stabilization assembly according to the invention.
- FIG. 1 represents two vertebrae respectively upper 2 and lower 2 ', intended to be connected by means of different types of stabilization devices according to the invention, which will be described in the following.
- Each vertebra comprises a vertebral body 4, 4 'extended by a pedicle 6, 6', an upper articular 8, 8 'and a lower articular 10, 10'.
- the intervertebral space is designated by 12, by 14, 14 ′ the facing articular facets, and by 16 and 16 ′ the articular capsules.
- two pedicle screws 18, 18 'fixed in the vertebral bodies 4, 4' corresponding.
- FIG. 2 represents an intervertebral stabilization device according to a first embodiment of the invention, which forms an extra-discal organ 20.
- the latter which is arranged at the rear of the intervertebral space 12, is suitable for cushion a displacement between the vertebrae 2, 2 '.
- the damping member 20 comprises a rigid cylindrical tank 22, made for example of metal, plastic, or ceramic. This tank receives, in its internal volume, a piston 24 which is pivotally mounted on the head 19 of the screw, which screw s. ' extends through an opening 26 formed in the tank 22.
- the lateral walls of the piston are separated from the interior walls • facing the tank by means of two O-rings 28.
- the lower end of the tank 22 is secured to the head 19 'of the lower screw 18'.
- the end walls 30 of the tank 22 define, with the end walls facing the piston 24, two respectively upper 32A and lower 34A chambers.
- the latter are brought into communication by a conduit 36A, extending in the main direction of the tank 22.
- This pipe which is for example made of metal or plastic, is connected to the tank 22 by crimping, screwing or snap-fastening.
- the cross section of this conduit 36A is substantially less than the cross section of each chamber 32A, 34A.
- This conduit 36A has for example a passage diameter of less than 2mm, advantageously between 0.2 and 0.9mm.
- the end walls 30 of the tank 22 are further provided with stops 38, made of a flexible material such as a polymer.
- Each room is filled with a damping fluid.
- This fluid comprises at least one liquid, such as water or oil.
- this damping member 20 is as follows. When the patient leans forward according to arrow F, this has the effect of distancing the vertebrae 2, 2 'from one another and therefore the pedicle screws 18, 18'. In this way, the movable piston 24, for separating the chambers, is directed towards the upper wall 30 of the tank 22 and thus drives the fluid out of the upper chamber 32A, in the direction of the lower chamber 34A. This flow, which occurs through the conduit 36A, is materialized by the arrow f.
- the speed of movement of the fluid through the conduit 36A which conditions the speed of movement- ment of the piston 24 in the direction of the upper wall 30 ′, is adjustable as a function of the section of the duct, the length of the latter and the viscosity of the fluid used.
- the upper stop 38 makes it possible to limit the aforementioned movement, by pressing the wall opposite the piston 24 against this stop 38.
- the elastic nature of the latter confers an additional damping component .
- FIG. 3 shows an alternative embodiment of the damping member 20 described in Figure 2.
- it uses an additional conduit 36B connecting the two chambers 32B, 34B.
- each conduit 36B, 37 is provided with a corresponding non-return valve 40, 42.
- the conduit 36B only allows a transfer of fluid from the upper chamber 32B to the lower chamber 34B, according to the arrow f, while the conduit 37 ensures movement of the fluid only from the lower chamber 34B to the upper chamber 32B , according to arrow f '.
- FIG. 4 illustrates an intervertebral stabilization device according to a second embodiment, which forms a disc implant 52 intended to be inserted at least partially between the vertebral bodies 4, 4 ′ of the vertebrae 2, 2 ′ of FIG. 1.
- This implant includes a pocket 54, made of a deformable but substantially non-extensible material.
- This pocket 54 defines two chambers respectively front 56A and rear 58A, which are connected by a conduit 60A, or throttle, bringing the internal volume of these two chambers into communication.
- This conduit 60 has transverse dimensions substantially smaller than those of the chambers 56A, 58A.
- the implant 52 also comprises a coating formed by two shells 62.
- Each of the latter which has a cross section substantially in an arc, is made of a rigid material, such as titanium.
- These shells 62 which are placed on either side of a median plane of the pocket 54, are intended to come into contact with the vertebral bodies 4, 4 '. They are secured to the pocket 54 for example by gluing.
- Each chamber 56A, 58A is filled by means of a fluid, similar to that contained in the chambers 32, 34 mentioned above.
- FIG. 5 represents an alternative embodiment of the implant 52 of FIG. 4.
- the two chambers 56B, 5fiB are connected, not by a conduit, but by a porous membrane 64, constituting an interface between these two bedrooms.
- This membrane 64 which can extend over the entire cross section of the chambers 56B, 58B, is for example made of a textile material, such as DACRON, or of a porous metal.
- DACRON a textile material
- the presence of the pores of this membrane 64 makes it possible to delay, in a similar manner to the use of the conduit 60, the transfer of fluid between the two chambers.
- the damping component thus imparted depends in particular on the size and the number of pores of the membrane 64.
- FIG. 6 represents an additional variant embodiment of the implant 52 described in FIG. 4.
- the chambers 56C, 58C are connected, not only by a first conduit 65, but also by an additional conduit 66, parallel to the conduit 65.
- Each conduit is provided with a respective non-return valve 68, 70.
- the conduit 65 allows a transfer of fluid only from the front chamber 56C to the rear chamber 58C, while the additional conduit 66 provides fluid transfer only in the opposite direction.
- the transverse dimensions of the conduit 65 are greater than those of the additional conduit 66, so that the fluid is more easily able to flow towards the rear chamber 58C, which corresponds to the bending movement towards the front of the patient.
- this forward flexion movement is damped to a lesser extent than the reverse rearward extension movement.
- at least one of the chambers belonging to the implant in this case the front chamber 56C, contains a volume of gas 72, which can for example be air or even nitrogen .
- This gas 72 is advantageous, insofar as it induces an elastic effect during the compression of the chamber 56C. In fact, when the latter is compressed, it is first of all the air 72 which is expelled therefrom, so that the corresponding movement is only damped to a very small extent.
- FIG. 7 represents an additional variant of the implant 52.
- the implant 52 does not have a pocket, but has end walls 74 sealingly connecting the shells 62. These walls 74 are made of a material deformable but not substantially extensible.
- a cylinder trunk 76 forming a piston, is housed in the interior volume of the implant 52.
- This cylinder trunk the main axis of which is transverse to that of the implant 52, forms a porous system . It contains for example a labyrinth system comprising small cells connected together by pores, which allows it to capture the fluid, so as to cause a slowdown in the flow of the latter.
- This piston 76 defines, with the walls 74 facing, two front chambers 56D and rear 58D.
- the movable piston 76 moves from back to front of the implant 52. This induces compression. sion of one of the chambers 56D, 58D, so that fluid escapes therefrom towards the other chamber, via the pores of the piston 76.
- FIG. 8 represents an alternative embodiment of FIG. 7, in which the piston 76 'is rigid and sealed.
- This piston constitutes, as in the embodiment of FIG. 7, a pivot for the two shells 62, which can pivot relative to one another around the main transverse axis A of this pivot.
- the circulation of fluid between the chambers 56E and 58E, which is not permitted by the piston 76 ', is ensured by means of at least one channel 78 formed in one of the rigid shells 62.
- FIG. 9 illustrates an additional variant of the invention.
- a chamber 56F capable of being used in one of the implants described with reference to the preceding figures.
- This chamber 56F comprises a bag 80, deformable but not extensible, the open end of which is fixed, for example by crimping, to a rigid cover 82, which is slidably mounted in a tank 84 with a closed bottom.
- the facing walls of the bag 80 and the tank 84 are separated by a lubricant 86, such as a silicone gel.
- a conduit 88 passes through the cover 82, so as to bring the internal volume of. room 56F with the outside.
- fluid escapes therefrom or is admitted therein, so that the edges of the cover 82 rise or fall, sliding, along the side walls of the tank 84.
- two chambers 56F can be connected by the conduits 88, so as to form an extra-discal member, of the same type as that of FIGS. 2 and 3.
- These chambers 56F can also be surrounded by shells, similar to those 62.
- the conduits 88 extend into the shells and at least one chamber can be surrounded by a helical spring.
- FIG. 10 illustrates an intervertebral stabilization device according to another embodiment, which forms a disc implant 102.
- the latter comprises two elements respectively left 104 and right 106, arranged on either side of the main axis A of the vertebral chain which, when the patient is in a standing position, is a vertical axis passing through the median plane P extending from back to front of the patient.
- Each element 104, 106 comprises two chambers respectively before 108, 112 and rear 110, 114.
- the two front chambers 108, 112 are put in communication by a front conduit 116, while the two rear chambers 110, 114 are connected by a conduit rear 118.
- the different chambers contain a fluid similar to one of those described above, so that, depending on the pressure conditions exerted on these chambers, a fluid communication is established between them.
- the chambers of the same element are separated by means of respective membranes 120, 122 which may be waterproof, or else porous like the membrane 64 described above. In this way, the two chambers 108, 110 and 112, 114 of an element considered can possibly be placed in fluid communication.
- the right front chamber 108 can be placed in fluid communication with the left rear chamber 114, the left front chamber 112 in this case being placed in fluid communication with the right rear chamber 110.
- These additional fluid relations can be achieved in a manner additional to the relationships permitted by conduits 116, 118.
- FIG. 11 represents a disc implant 102 ′ comprising two rear chambers, respectively right 124 and left 126, as well as a front chamber 128, extending over a substantial part of the width of the disc.
- the rear chambers 124, 126 are placed in fluid communication via a conduit 130.
- each of these chambers 124, 126 is placed in fluid communication with the front chamber 126, via respective conduits 132, 13'4.
- the implants 102, 102 ′, described above, induce an additional damping component, when the patient bends over the sides, since they use chambers arranged on either side of the axis AT.
- FIG. X 2 represents an intervertebral stabilization device in accordance with an additional embodiment, which is generally designated by the reference 150.
- This device comprises a disc implant 152, intended to be inserted at least partially into the intervertebral space 12.
- This implant 152 comprises two chambers respectively front 156 and rear 158, surrounded by two shells 162, similar to those 62 described above.
- the device 150 also comprises a damping member 170, arranged in a similar manner to that described above, namely at the rear of the intervertebral space 12.
- This member 170 comprises a rigid vessel 172 inside which is disposed a piston 174, which comprises a head 176, forming an upper end, the transverse dimensions of which are close to those of the tank.
- An O-ring seal 178 is mounted between the walls facing the head 176 and the tank 172.
- the head 176 of the piston extends from a vertical rod 180 which crosses, in a sealed manner, the lower wall
- the lower end of the rod 180, opposite to the head 176, is ball-mounted on the head 19 'of the lower screw 18'.
- the head 176 delimits respectively upper 186 and lower chambers 188, of the tank 172.
- the upper chamber 186 receives a spring 190, working in compression, which extends vertically between the upper wall of the tank and the facing wall of the head 176.
- This spring 190 allows the piston 174 to be returned to its low position, which corresponds to a lordosed posture of the patient, physiologically advantageous.
- the front chamber 156 of the implant 152 is placed in fluid communication with the upper chamber 186 of the member 170, via a conduit 192, while the rear chamber 158 is placed in fluid communication with the lower chamber 188 via an additional conduit 194.
- fluid is expelled from the front chamber 156 in the direction of the upper chamber 186, which contributes to lowering the piston 174 into the tank 172, opposite the upper screw 18.
- This rise induces a displacement of fluid, via the conduit 194, from the lower chamber 188 towards the rear chamber 158. This bending movement is therefore damped by these different fluid flows.
- the amplitude of this damping can be modulated as a function of the characteristics of the fluid admitted into the different chambers and of the passage section of the conduits 192, 194. It is easily understood that, during a movement of extension of the patient towards the rear, there is both fluid flow and movement of the piston 174, in opposite directions to those mentioned above. As a variant, provision may be made to add two additional conduits to each of the conduits 192, 194, the four conduits thus formed being provided with non-return valves ensuring the flow of the fluid in a single direction. It is also possible to provide that the membrane 196 separating the front 156 and rear 158 chambers is porous, so as to allow a flow of fluid between these two chambers.
- These chambers 186, 188 can be brought into communication by several conduits extending in the wall of the tank 172. These conduits can be arranged one at a time. below the others, so that the head 176 of the piston, as it moves, successively closes the outlets of these conduits. At the end of movement, there therefore remains, in a chamber considered, a volume of residual fluid which cannot be expelled and constitutes a volume of damping.
- the tank may have a double wall defining an annular fluid reserve housing.
- the tank can also be made partially of a porous material, such as a ceramic.
- a piston rod 180 174 passing through the walls of the tank 172 is advantageous. Indeed, this rod 180 and therefore the piston 174, can be connected to the screw 18 'while providing that the latter is located outside of the tank 172. This is advantageous in terms of sealing, insofar as it is necessary to provide only a sealing member in the vicinity of the opening of the tank, through which extends the aforementioned rod.
- an intervertebral stabilization device comprising a disc implant and a damping member, disposed at the rear of the intervertebral space.
- the intervertebral implant makes it possible to restore the height of the disc.
- this implant contains a fluid, it is able to confer on the two neighboring vertebral bodies a certain freedom of mutual movement.
- the extra-discal damping member makes it possible to regulate the movements authorized by the discal implant.
- the stabilization device 150 can be arranged offset from the main axis A, that is to say that the implant 152 and the member 170 are arranged on the same side of the plane P. Such an arrangement makes it possible to remedy asymmetrical collapses of the intervertebral space, seen from behind.
- the invention is not limited to the examples described and shown. Indeed, provision can be made to connect, by means of an intervertebral stabilization device according to the invention, two vertebrae which are not neighboring.
- the fluid communication means described above control the flow of the fluid because they induce a limitation of the flow of this fluid, during its flow between the chambers thus connected. This can be done by giving these communication means reduced transverse dimensions, or even a considerable length. These means induce a restriction, a slowing down of the flow of the fluid and / or a pressure drop of the latter.
- the flow of fluid between the chambers is kept at a value below a limit value, which guarantees that the passage of the fluid from a first chamber to a second chamber is not too rapid. A certain damping of the movements of the patient's column is thus created.
- Providing that two adjacent chambers are separated by a movable member, such as a piston, is particularly advantageous. Indeed, this makes it possible to produce objects, extradiscal and / or intradiscal, which are effective, compact and which are only subjected to a small extent to the problems of sealing.
