Definitions
- the present invention relates to a novel implant for medical use for fixing at least two adjacent bone elements quickly, reliably and minimally invasive.
- the present invention also describes a method of attaching at least two adjacent bone elements implementing this new implant. This method is particularly suitable for the joining of at least two vertebrae for performing arthrodesis; said implant being of curved shape which makes it particularly suitable for spine surgery.
- bone problems generate or are part of the clinical picture of many pathologies.
- trauma associated with accidents, shocks and falls may also cause bone problems requiring surgery.
- the possibility of fixing bone elements together in order to stabilize or correct a given position is therefore an important medical issue. Indeed, in the field of spine surgery in particular the fact of being able to join bone elements in order to stabilize given areas and / or to release compressed nerve bundles is often the only way to relieve patients.
- the techniques used to date have several drawbacks, including the complexity of the devices to be implanted, the transepicular approach for the fixation screws of these devices which is relatively invasive and generates side effects (hemorrhages, nerve damage, etc.). the need for follow-up involving imaging techniques performance, ie all of the risk factors, technical factors and costs that must be taken into consideration.
- the curved implant is one of these solutions, and has never been proposed to date. Indeed, the implant according to the invention has the advantage of allowing the establishment of a solid attachment requiring a single access path.
- the curved shape makes it possible to work access ways offering working angles that are not suitable for the rectilinear screws known from the prior art.
- the present invention proposes a simple surgical implant which makes it possible to achieve the fixation of at least two adjacent bone elements, for example two adjacent vertebrae, without risk of false journey, without particular technical difficulty and without expensive technical assistance other than a simple apparatus. of fluoroscopy.
- the implants according to the present invention are not positioned in the vertebral pedicles but allow to directly fasten the vertebral bodies together.
- the device is immediately more solid than pedicle screws commonly used in the prior art.
- the present invention therefore also proposes a new method of fixing at least two adjacent bone elements, for example two adjacent vertebrae, without the risk of false path and without particular technical difficulty for a surgeon.
- This method also saves considerable time in the case of the stabilization of more than two adjacent bone elements such as several vertebral stages.
- this new surgical implant is placed directly in the bone element, without staples or nails, so an arthrodesis operation for example can be performed closed rachis between the nerve bundles and without damaging the nerves.
- patient is meant a human being or an animal whose symptoms or pathology require the intervention of a surgeon for the joining of at least two bone elements between them.
- a patient is an individual who has had a vertebral fracture or scoliosis, a vertebral collapse, etc. the method proposed to relieve the pain of said patient being performing arthrodesis, that is to say the bone fusion between two vertebrae.
- Body element means anatomical bone elements requiring stabilization or repair surgery, but also any implant that completely or partially replaces an anatomical bone element, for example an implant made of a metal or alloy of metal, ceramic, polymer, or any other biocompatible material.
- the invention relates to a surgical implant for attaching at least two adjacent bone elements of a patient, said implant being constituted by a rod intended to be sealed by means of a sealing element in a borehole in the at least two adjacent bone elements, characterized in that said rod is curved and hollow so as to form an open channel at one end and having at least one gap so as to allow the sealing member to it is injected into said channel via the open end to flow outside the rod in contact with the bone elements to be sealed.
- rod is meant a solid element, preferably of cylindrical shape and which constitutes the body of the implant according to the invention.
- curve is meant a shape describing or comprising a flat arc or three-dimensional portion, not necessarily regular.

- curvature or “regular arc of curvature”.
- the stem When it is mixed, the stem has a straight portion and at least a curved portion without the stem necessarily having symmetry.
- the composite rod may have two, three or more curved portions. We will then speak of "curvature” or “mixed arc of curvature”.
- “Hollow” means that the rod comprises over all or part of its length a bore in the longitudinal direction so as to form a channel, said channel being open on one end of the rod (so as to introduce a sealing element not this open end).
- the channel is open at the so-called “rear” or “distal” end of the stem, the other end, called “before” or “proximal” being full and may have a pointed shape intended to facilitate the penetration of the stem within the bone elements.
- the channel may also be open at the proximal end of the stem so as to allow the flow of the sealing element at this level as well.
- hole (s) means openings or windows on all or part of the rod which allow the channel formed within the rod to communicate with the outside of the rod.
- one or more longitudinal slots which may extend over all or part of the rod.
- any sealing element injected into the channel may flow and disperse outside the rod in direct contact with the bone elements to be sealed.
- the arrangement of the gaps may be adapted according to the general knowledge of those skilled in the art.
- the invention also relates to a surgical implant, further characterized in that said at least one gap consists of a plurality of openings distributed along the shaft.
- the surgical implant according to the invention is particularly suitable when said bone elements are vertebrae.
- the rod is in the form of a regular cylinder.
- the stem may comprise an anchoring element present on all or part of the length of the stem and projecting towards the bone element.
- At least one of the anchoring elements is a net.
- This net can be made according to different profiles, in particular rounded or sharp depending on whether an anchoring is sought by pressing on the bone element or by insertion into it.
- the at least one net is not of constant height all along.
- the height of the net emerging from the opening may be variable.
- the invention may also be made with an absence of net on certain part of the stem including those which will be surrounded by a non-bone tissue area once the implant is in place.
- the net has on its walls elements such slats or pins, optionally scored, to anchor said net in the bone without the possibility of return unless constrained by a movement exerted by the surgeon with the torque needed to fold or break them.
- the shape of the stem determines the shape of the implant, so in a particular embodiment, the stem is curved and the surgical implant once it is in place is also curved. In a specific embodiment, the stem is curved in different planes. According to an additional characteristic, the shape of the surgical implant according to the invention is curved. According to another additional characteristic, the shape of the surgical implant is mixed, that is to say that it has one or more straight portions and one or more curved portion (s).

- the present invention also relates to a surgical implant characterized in that the stem comprises at least a curved portion
- the materials used for producing the surgical implant according to the invention are biocompatible solid materials, for example of the metal or metal alloy type, in particular titanium or alloys based on titanium and / or steel or alloys based on of steel, ceramics for medical use, polymeric materials for medical use, said materials being considered alone or in combination.
- the rod is made of metal or a metal-based alloy.
- the rod is made of different biocompatible materials so as to have, according to its sections, properties, in particular of different flexibility.
- it is possible to envisage different surface treatments of the stem for example to ensure the biocompatibility, the cutting edge, the spring effect, the sliding or on the contrary the adhesion of one or other of these elements.
- the rod When the rod is made of a rigid material, the surgeon must drill into the bone elements to assemble which curvature is identical to that of the rod.
- the rod When the rod is made of a solid but flexible material, the rod is capable of adapting to any curvature of the drilling performed by the surgeon according to predefined parameters.
- the rod is made of one or more flexible biocompatible material (s).
- the rod may in particular have a nail shape.
- the present invention also relates to a surgical implant, characterized in that the rod is made of one or more biocompatible materials which are flexible.
- the implant may be envisaged to make only certain portions of the rod in a flexible material.
- the flexible portions may be provided to be positioned outside the bone elements to be assembled, for example two vertebrae so as to form a kind of hinge and maintain some flexibility to the implant.
- the present invention also relates to a surgical implant, characterized in that only some of the portions of the shaft are flexible.
- this surgical implant makes it particularly adaptable to the morphology of the adjacent bone elements to be fixed between them. Indeed, it is easy to manufacture "custom-made" surgical implants of substantially curved shape, having a symmetry or not by relative to said curve, etc. All forms are permitted in the present invention depending on the area to be implanted. For implantation at the vertebral level, for example, a curved surgical implant will be preferred in order to adapt to the morphology of the vertebrae and to their articulation. The curvature is then determined according to the morphology of the bone elements to be joined. The curvature of the implant according to the invention will not necessarily be flat and may present twists.
- the stem has a diameter of between 3 and 9 mm, preferably around 6 mm.
- the stem is of curved shape in a plane, with a developed length of 70 mm describing an arc of 44.6 ° and of constant constant radius at 90mm.

- this section is advantageously chosen by those skilled in the art depending, in particular, the nature of the sealing element that will be used.
- the present invention also relates to a surgical implant characterized in that the channel of the stem has a section with a diameter of between 2 and 8 mm, preferably around 3 mm.
- the gaps may be in the form of circular, oval, square, rectangular, etc.
- circular holes will be described here. In view of the dimensions described, the Man art can easily deduce the equivalent surface of these gaps in the case where the shape differs.
- the circular holes have a diameter of between 0.5 and 5 mm.
- the gaps have the same diameter.
- the gaps may have different diameters along the rod, in order to control the amount of sealing element that may flow from the rod as a function of the positioning of the rod within the rods. bone elements to seal.
- the present invention also relates to a surgical implant characterized in that the gaps have a diameter of between 0.5 and 5 mm.
- the gaps are advantageously arranged along the rod, depending in particular on the nature of the elements to be sealed, the nature of the sealing element, and so on.
- the rod has gaps on one or the other or both ends.
- the rod has gaps along its length.
- the respective diameters of the channel section and gaps will be determined primarily according to the sealing member that will be used.
- the more the sealing element will be fluid and homogeneous the more these two diameters may be small.
- the more the sealing element will be heterogeneous or viscous the larger these two diameters will be to allow a sufficient flow of the sealing element. Based on his general knowledge, the skilled person will have no problem to adapt these two diameters to the nature of the sealing member as will be apparent from the examples below.

- acrylic cements have the property of being injected in a relatively homogeneous, liquid or fluid form. By this property, the section of the channel and the diameter of the gaps at both ends can be reduced
- bone cells or an osteoinductive protein it is possible to use bone cells or an osteoinductive protein.
- the INDUCTOS ® products can be cited.
- bone substitutes are generally in a form less homogeneous and more viscous than an acrylic cement. Those skilled in the art will be able to adapt the section of the channel and the section of the gaps to this viscosity.
- the implant according to the invention has at least one hooking device for the installation and removal of the rod by the surgeon using appropriate ancillaries.
- This device is according to a preferred embodiment the hooked device is located on a portion of the end of the rod not inserted into the bone element.
- the hooking device can consist of any means known to those skilled in the art, such as for example a thread, a hook, a ring, a notch, a flat, a magnet, a relief, an impression, a withdrawal, a perforation.
- the invention also proposes a method for fixing at least two bone elements, implementing the implant
- the present invention relates to a method of fixing at least two adjacent vertebrae which implements a surgical implant as described above, said method comprising: practicing with the aid of a tool drilling a drill having the characteristics defined by the surgeon according to the vertebrae to be joined, and then - insert the rod in the borehole thus performed using a placement tool under medical fluoroscopy, then
- FIG. 4 shows the injection of the sealing element (8) via the open end (6) of the rod (4), said sealing element then flowing through the holes (7) directly in contact with the adjacent vertebrae (2, 3).
- FIG. 1 shows a rod (4) of curved shape with a regular curvature arc. More particularly, there is shown in Figure 1 an implant (1) according to the invention consisting of a rod (4) curved and hollow so as to form within it a channel (5) open at the distal end (6) of the rod (4). In this embodiment, the proximal end (7) is solid and is in the form of a tip.
- the rod (4) shown comprises in this embodiment adapted to the use of an acrylic cement several gaps (8) in communication with the channel (5) distributed near the ends (6, 7) of the rod (4).
- Figure 2 illustrates the rod (4) at the moment when it will be inserted into a borehole (10) previously made by the surgeon.
- the advantage of the curved shape of the rod (4) clearly emerges from this figure where we see the ease of installation of the implant.
- the rod (4) can be inserted using a drilling tool and laying within two adjacent bone elements, here two vertebrae (not shown tool).
- Figure 3 shows the rod (4) once positioned within two vertebral bodies (2, 3) to be secured.
- this rod (4) has holes (8) advantageously arranged at both ends to allow the cement to come into contact only with the bone parts of the vertebrae (2, 3) but to avoid any contact at the level of the intervertebral spaces.
- This aspect is of particular interest in the context of the use of an acrylic cement as has been described above.
- the open end (6) is advantageously arranged to allow easy access to facilitate the injection of cement by the surgeon.
- Figure 4 shows the surgical implant (1) in its final position within two adjacent vertebral bodies (2, 3) in our example.
- the cement (11) is then injected via a syringe (12) or any other equivalent device directly into the channel (5) formed in the rod (4).
- the latter will then flow out of the rod (4) via the gaps (8) directly in contact with the vertebrae (2, 3).
- this flow of cement will allow the latter to come to fill the bone trabeculae of the vertebrae (2, 3) and thus to avoid problems or complications related to the phenomenon of pseudoarthrosis.
- the surgical implant (1) may have a hooking device so that the surgeon can easily install and remove it.
- This hanging point is ideally located at the proximal end (7) of the surgical implant (1), ie at the point of insertion of the stem (4) into the first element. bony. Removal of the surgical implant (1) or removal is done by performing the same operations as the pose but in the reverse order.
- This method is particularly suitable for the fixation of several adjacent vertebrae in a patient presenting a lumbar problem requiring the intervention of a surgeon because it avoids the insertion of pedicle screws according to the techniques currently used, which is less invasive and greatly limits the side effects related to the vertebral fixation operation.
- the operation can be considered spine closed under fluoroscopic control, passing between the nerve bundles and without damaging the nerves.
- the present invention also relates to kits or kits containing the equipment necessary for the implementation of the method described above.
- the present invention relates to kits or kits containing a surgical implant in one of the embodiments detailed above.
- the present invention also relates to a kit comprising a surgical implant as described above.
- the present invention relates to kits or kits containing a surgical implant in one of the embodiments detailed above and a drilling tool.
- the present invention relates to kits or kits containing a surgical implant in one of the embodiments detailed above, a drilling tool and a tool for installing the rod; these two tools forming an ancillary kit.
- the kit or kit includes a curved surgical implant and an ancillary kit.
