Definitions
- the present invention relates to an interbody spinal immobilization cage of the type comprising a central hollow space intended to be filled with bone fragments in order to allow an osteosy thesis.
- an intersomatic implant is to restore and maintain an inter-vertebral space, and to obtain a bone fusion of the two vertebral bodies adjacent to each other, called "osteosynthesis".
- the interbody implants are hollow and provided with a multitude of holes of various shapes; the hollow space is intended to allow the insertion of one or more bone grafts and the holes are intended to allow the grafts to develop in contact with the vertebral bodies in order to obtain a solid and lasting bone fusion of these same bodies vertebral.
- intersomatic cages comprising a central hollow space intended to be filled with bone fragments
- the intersomatic cage is formed by a cylinder of steel in which eight holes equally spaced in the axial direction were drilled, each hole being centered on a circle concentric with the axis of the cylinder and in which a large hole was drilled, centered on the axis and having a substantially identical radius at that of the circle mentioned above.
- a V shape is also provided in the external surface of the cylinder, thus creating a succession of bumps and hollows, each crossing of a hollow with one of the eight holes thus achieving a perforation.
- the internal surface of the cylinder has a screw thread.
- This intersomatic cage in the shape of a hollow cylinder can thus be screwed into a bone cavity comprising a screw pitch complementary to the V shape.
- a bone fusion takes place then between the bone cavity and the grafts, thanks to the perforations.
- US Pat. No. 5,263,953 which relates to a cage for bone fusion having a helical structure composed of helical turns which are not axially contiguous.
- the helical structure ends at its two ends by radial sections, oriented perpendicular to the axis of the helical structure, both intended to cooperate with grooves made on the instrument used for implantation.
- These two radial sections make it possible to operate a prestress on the helical structure, so that the diameter of this structure decreases, in order to allow the helical structure to be installed.
- the purpose of the helical structure is therefore to allow radial expansion after implantation.
- the cage is therefore not screwed into the bone cavity.
- the major drawback of the intersomatic cages of the prior art lies in the fact that they cannot be removed subsequently without damaging the bone fusion which has taken place inside and through it.
- the present invention intends to remedy the drawbacks of the prior art by proposing an interbody cage which can be removed easily after bone fusion without at all damaging the fusion which has taken place.
- bone fusion can end in the space previously occupied by the structure of the cage and the bone quickly regains its initial dimensions.
- the present invention is of the type described above and it is remarkable, in its broadest sense, in that said hollow space is delimited by a helical structure composed of helical turns not axially contiguous, in order to allow remove said cage by unscrewing the helical structure.
- a helical turn means a winding over substantially 360 °, not closed at its center, said winding having a central cavity.
- the helical structure according to the invention is thus preferably formed of several turns, in order to ensure good immobilization and these turns are not axially contiguous, that is to say that an interspire space is produced between each successive turn in the direction of the axis of the helical structure, to allow bone fusion between the grafts, the bone cavity and the adjacent vertebral bodies, through the free space between the turns.
- the interbody cage according to the invention can be removed at any time, by simply unscrewing the helical structure composed by the helical turns.
- Said helical turns may have in section a circular or oblong shape or a pentagon shape having a pronounced base.
- the intersomatic cage according to the invention preferably comprises, at an axial end, a means for gripping and / or joining with other implants.
- the intersomatic cage according to the invention preferably ends at a distal axial end, with a progressive reduction in the section.
- the present invention also relates to a method for producing an interbody cage, in which said interbody cage is obtained by recessing the central core of a screw.
- the present invention makes it possible to very easily remove the bone fusion cage, without damaging the fusion effected, simply by unscrewing the helical structure.
- the present invention also makes it possible to very easily implant the bone fusion cage, simply by screwing the helical structure. No other element is provided inside the helical structure, so as not to hinder these unscrewing screwing operations.
- FIG. 1 illustrates a partial view of a intersomatic cage according to the invention
- - Figure 2 illustrates a partial view of an interbody cage according to the invention comprising a grasping washer
- FIG. 3 illustrates a partial view of an intersomatic cage according to the invention, the turns of which have an oblong shape in section
- FIG. 4 illustrates a partial view of an intersomatic cage according to the invention produced by recessing the central core of a screw.
- the interbody cage (1) according to the invention is an interbody cage for immobilizing the rac is intended to be implanted in a bone cavity and comprising a central hollow space (2) intended to be filled with bone grafts.
- the intersomatic cage (1) according to the invention is characterized in that the hollow space (2) is delimited by a regular helical structure (3) composed only of helical turns (4) not axially contiguous, that is to say say, separated by an identical pitch and not touching in the direction of the axis A of said helical structure (3), in order to allow said cage to be removed by unscrewing the helical structure, that is to say in turning the helical structure in the opposite direction of the pitch.
- the pitch of the helical structure can be oriented to the left or to the right; it does not matter.
- the helical structure illustrated in Figure 1 has 5 turns, but their number does not matter, only the external dimensions of the helical structure are important. It could, for example, be imagined to produce a helical structure comprising 4 and a half turns or 6 turns.
- one or more bone grafts can be deposited in said hollow space (2) and the bone fusion between the bone cavity and the bone grafts takes place through the interspire spaces (8) located between the helical turns (4) and possibly by the axial end space (s) (5, 5 ').
- the helical structure (3) is similar to that of a regular helical spring, but no quality of elastic return specific to helical springs, following for example an axial compression or an axial extension, is used here.
- the helical structure, composed of several turns, is only used for its ability to be unscrewed once the fusion has taken place, so as not to damage this fusion at all during the ablation of the cage.
- the interbody cage (1) comprises, preferably at its proximal axial end (5) a gripping means (6) and / or junction with other implants, as illustrated Figure 2.
- This gripping means (6) and / or junction with other implants is made, for example, by a washer having in its center a threaded hole.
- Said helical turns (4) have in section a shape facilitating the unscrewing of the interbody cage and, for example, have a circular shape.
- Said helical turns (4) may also have an oblong shape in section, as illustrated in FIG. 3, in order to improve immobilization by increasing the depth of anchoring of the interbody cage in the adjacent vertebral bodies in radial directions relative to to axis A.
- the present invention also relates to a method for producing an interbody cage (1), characterized in that said interbody cage (1) is obtained by recessing the central core of a screw (7), as illustrated in FIG. 4.
- said helical turns (4) have in section a pentagon shape having a pronounced base, corresponding to the face in contact with the central hollow space (2).
- This method makes it possible to easily and quickly produce an intersomatic cage (1) according to the invention comprising means for its implantation and its ablation if the head of the screw is also kept at least partially.
