Description
IMPLANT INTER-SOMATIQUE.INTER-SOMATIC IMPLANT.
L'invention concerne un implant inter-somatique, plus particulièrement destiné à être inséré entre les corps vertébraux de deux vertèbres consécutives, notamment au niveau cervicale ou au niveau lombaire, en vue de réaliser la fusion des corps vertébraux à ce niveau. Il est connu depuis longtemps déjà de réaliser la fusion des corps vertébraux, afin de soulager la douleur des patients, inhérente aux pathologies chroniques affectant un ou Io plusieurs disques intervertébraux cervicaux ou lombaires, parmi lesquelles on peut citer les affaissements discaux majeurs avec sténose foraminale, les discopathies iatrogènes, les dysfonctionnements disco-ligamentaires chroniques mono- ou oligosegmentaires, les hernies discales, les spondylolisthésis, et de manière générale les The invention relates to an inter-somatic implant, more particularly intended to be inserted between the vertebral bodies of two consecutive vertebrae, in particular at the cervical level or at the lumbar level, with a view to achieving the fusion of the vertebral bodies at this level. It has long been known to carry out the fusion of the vertebral bodies, in order to relieve the pain of the patients, inherent in chronic pathologies affecting one or Io several cervical or lumbar intervertebral discs, among which one can cite major disc sagging with foraminal stenosis, iatrogenic disc diseases, chronic mono- or oligosegmental disco-ligament dysfunctions, herniated discs, spondylolisthesis, and generally
instabilités vertébrales.vertebral instabilities.
Parmi les solutions techniques envisagées pour aboutir à la fusion des corps vertébraux, il a été suggéré d'insérer entre les deux corps vertébraux consécutifs concernés, une cage inter-somatique, qui, de manière traditionnelle, constitue une cale insérée entre les plateaux en vis à vis des deux corps vertébraux concernés, définissant un volume à l'intérieur duquel est mis en place un ou plusieurs greffons d'os, Among the technical solutions envisaged to result in the fusion of the vertebral bodies, it has been suggested to insert between the two consecutive vertebral bodies concerned, an inter-somatic cage, which, traditionally, constitutes a wedge inserted between the screw plates with respect to the two vertebral bodies concerned, defining a volume inside which is placed one or more bone grafts,
notamment spongieux, de telle sorte à réaliser une greffe vertébrale inter-somatique. in particular spongy, so as to carry out an inter-somatic vertebral graft.
A cet effet, les parois notamment supérieure et inférieure de la cage en question To this end, in particular the upper and lower walls of the cage in question
présentent des lumières traversantes, pour permettre à la greffe osseuse de prendre. have through lumens to allow the bone graft to set.
Si, sur le plan théorique, cette solution technique apparaît séduisante, l'expérience démontre qu'au niveau pratique la fusion intervient de manière non satisfaisante entre If, on the theoretical level, this technical solution appears attractive, experience shows that at the practical level the fusion occurs in an unsatisfactory way between
les deux corps vertébraux consécutifs concernés. the two consecutive vertebral bodies concerned.
Le caractère non satisfaisant de cette fusion est inhérent à différents facteurs. Tout d'abord, un facteur anatomique, dans la mesure o les cages inter-somatiques de l'art antérieur, présentent un profil généralement parallélépipédique ou cylindrique, ne correspondant pas au profil particulier anatomique des plateaux intervertébraux. De la sorte, il n'y a pas, au niveau de la cage, de réelles contraintes, nécessaires au développement de la greffe d'os, et partant aboutissant à la fusion des corps vertébraux. En outre, cette absence de forme adaptée à l'anatomie explique les micro-mouvements de l'implant entre les plateaux vertébraux, qui entraînent des risques de pseudarthroses, et le recul de l'implant, si celui-ci n'est pas stabilisé par une The unsatisfactory nature of this merger is due to various factors. First of all, an anatomical factor, insofar as the inter-somatic cages of the prior art, have a generally parallelepiped or cylindrical profile, not corresponding to the particular anatomical profile of the intervertebral plates. In this way, there are no real constraints at the level of the cage, necessary for the development of bone grafting, and therefore leading to the fusion of the vertebral bodies. In addition, this absence of shape adapted to the anatomy explains the micro-movements of the implant between the vertebral plates, which involve risks of non-union, and the retraction of the implant, if the latter is not stabilized. by one
ostéosynthèse postérieure complémentaire. additional posterior osteosynthesis.
Afin de palier ces inconvénients, on a proposé, par exemple dans le brevet français FR-A-2 813 519, un implant inter-somatique souple, susceptible de se déformer élastiquement sous l'effort de pression engendré par les corps vertébraux, afin de In order to overcome these drawbacks, it has been proposed, for example in French patent FR-A-2 813 519, a flexible inter-somatic implant, capable of deforming elastically under the pressure force generated by the vertebral bodies, in order to
favoriser le contact du greffon avec les corps vertébraux sus- et sousjacents. promote contact of the graft with the overlying and underlying vertebral bodies.
Pour autant, un tel implant souple ne permet pas de réaliser la fonction de calage, However, such a flexible implant does not allow the setting function to be achieved,

Qui plus est, il n'est pas possible avec un tel implant de prévoir un calage différentiel, i5 c'est à dire d'amplitude et d'orientation souhaitées, fonction de la pathologie What is more, it is not possible with such an implant to provide for differential timing, i5 of desired amplitude and orientation, depending on the pathology

L'objet de la présente invention vise à surmonter ces différents inconvénients. The object of the present invention aims to overcome these various drawbacks.
Elle propose à cet effet un implant inter-somatique, permettant tout à la fois une adaptation anatomique de l'implant aux corps vertébraux au niveau desquels il est destiné à être implanté, sans nécessiter pour autant une quelconque ostéosynthèse postérieure associée, et d'autre part, d'assurer la fonction de calage, selon une To this end, it proposes an inter-somatic implant, allowing both an anatomical adaptation of the implant to the vertebral bodies at the level of which it is intended to be implanted, without requiring any associated posterior osteosynthesis, and other part, to ensure the timing function, according to a
orientation différentielle.differential orientation.

plateau supérieur du corps vertébral inférieur. upper plateau of the lower vertebral body.
Cet implant se caractérise en ce que par défaut, les deux branches forment entre elles un angle réduit convergent par rapport à leurs zones de jonction, et en ce que chacune des deux branches supérieure et inférieure est munie d'un filetage interne ou une goulotte interne, orienté selon la dimension principale des branches, et destiné à coopérer avec une vis, pour aboutir à l'écartement des branches, selon une angulation voulue. En d'autres termes, l'invention propose une cage inter- somatique rigide, à effet dynamique, ledit effet étant sélectionné par le praticien lors de l'intervention chirurgicale de mise en place de l'implant, en actionnant une vis dont le degré de vissage induit une plus ou moins grande divergence des branches supérieure et inférieure, constitutives de la cage. Ce faisant, il devient possible, avec l'implant inter-somatique conforme à l'invention, d'aboutir à un calage en cyphose ou en lordose, en fonction de la pathologie diagnostiquée, ladite cage étant cyphosante par défaut, et susceptible de devenir lordosante de manière progressive, typiquement entre - 5 O à + 8 par rapport à la This implant is characterized in that by default, the two branches form between them a reduced convergent angle with respect to their junction zones, and in that each of the two upper and lower branches is provided with an internal thread or an internal chute. , oriented along the main dimension of the branches, and intended to cooperate with a screw, to result in the spacing of the branches, at a desired angle. In other words, the invention provides a rigid inter-somatic cage, with a dynamic effect, said effect being selected by the practitioner during the surgical operation for placing the implant, by actuating a screw whose degree screwing induces a greater or lesser divergence of the upper and lower branches, constituting the cage. In doing so, it becomes possible, with the inter-somatic implant according to the invention, to result in a setting in kyphosis or in lordosis, depending on the pathology diagnosed, said cage being kyphogenic by default, and likely to become lordosing gradually, typically between - 5 O to + 8 compared to the
direction parallèle moyenne définie par les deux plateaux vertébraux concernés. mean parallel direction defined by the two vertebral plates concerned.
Selon une caractéristique de l'invention, le filetage ménagé au niveau des branches supérieure et inférieure, est susceptible d'être détruit, ou simplement déformé au moyen d'un outil approprié, après mise en place de la vis selon le degré de vissage souhaité, lui-même dépendant de l'orientation souhaitée des branches Selon une autre caractéristique de l'invention, les branches supérieure et inférieure présentent un profil bombé, selon la direction principale des branches d'une part, et According to a characteristic of the invention, the thread formed at the level of the upper and lower branches is capable of being destroyed, or simply deformed by means of an appropriate tool, after positioning the screw according to the desired degree of screwing. , itself dependent on the desired orientation of the branches According to another characteristic of the invention, the upper and lower branches have a convex profile, in the main direction of the branches on the one hand, and

En outre, le sommet du dôme ainsi réalisé est sensiblement situé à la jonction du tiers postérieur et des deux tiers antérieurs, mesurés par rapport à la plus grande dimension In addition, the top of the dome thus produced is substantially located at the junction of the posterior third and the anterior two thirds, measured with respect to the largest dimension.
desdites branches, dans un souci d'une plus grande adaptation anatomique. said branches, for the sake of greater anatomical adaptation.
Selon une autre caractéristique de l'invention, l'implant présente une surface médiane réduite, permettant d'obtenir une surface de contact prédéterminée et choisie, avec un deuxième implant symétrique destiné à venir s'insérer également au niveau de l'espace inter-vertébral. On définit ainsi un implant gauche et un implant droit, les deux implants étant symétriques l'un de l'autre par rapport à leur surface latérale destinée à According to another characteristic of the invention, the implant has a reduced median surface, making it possible to obtain a predetermined and chosen contact surface, with a second symmetrical implant intended to be inserted also at the level of the space between vertebral. A left implant and a right implant are thus defined, the two implants being symmetrical to one another with respect to their lateral surface intended for

L'implant inter-somatique conforme à l'invention a été tout particulièrement représenté en relation avec la figure 2. Il est destiné à être inséré entre les plateaux The inter-somatic implant according to the invention has been particularly shown in relation to Figure 2. It is intended to be inserted between the plates
vertébraux (15, 16) de deux vertèbres consécutives (voir figure 1). vertebrae (15, 16) of two consecutive vertebrae (see Figure 1).
Il est réalisé en tout matériau, notamment en titane, voire en polyetherétherkétone, commercialisé sous la marque PEEK. Ce matériau est bien connu pour être stable et par ailleurs radio-transparent, permettant notamment de contrôler parfaitement la fusion lorsque celle-ci est intervenue. Qui plus est ce matériau est également connu pour présenter une élasticité se rapprochant le plus de l'os, favorisant de fait le It is made of any material, in particular titanium, or even polyetheretherketone, sold under the brand PEEK. This material is well known for being stable and also radio-transparent, in particular making it possible to perfectly control the fusion when it has occurred. What is more, this material is also known to have an elasticity closest to the bone, thereby favoring the
phénomène de fusion recherché.phenomenon of fusion sought.
Selon l'invention, cet implant inter-somatique est constitué d'une cage rigide, définie par une branche supérieure (2), une branche inférieure (3) , solidarisée au niveau de According to the invention, this inter-somatic implant consists of a rigid cage, defined by an upper branch (2), a lower branch (3), secured at
l'une de leur extrémité par une zone de jonction (4). one of their ends by a junction zone (4).
En revanche, leur autre extrémité est libre, définissant une fente (11), tel qu'on peut However, their other end is free, defining a slot (11), as can be
bien l'observer sur la figure 2.observe it well in figure 2.
En d'autres termes, l'implant inter-somatique conforme à l'invention, présente une In other words, the inter-somatic implant according to the invention has a
fente obturée au niveau de la zone de jonction (4). slot closed at the junction zone (4).
Selon une caractéristique de l'invention, en l'absence de contraintes externes, l'orientation de la fente à partir de la zone de jonction (4) est convergente. En d'autres termes, la fente a une largeur plus faible au niveau de l'extrémité libre de la fente (11) According to a characteristic of the invention, in the absence of external constraints, the orientation of the slot from the junction zone (4) is convergent. In other words, the slot has a narrower width at the free end of the slot (11)
qu'au niveau de la zone de jonction (4). than at the junction zone (4).
L'objectif recherché est qu'en l'absence de contrainte, l'implant intersomatique, The objective sought is that in the absence of constraint, the interbody implant,
produit un effet cyphosant par défaut lors de sa mise en place. produces a kyphogenic effect by default when it is put in place.
La cage ainsi réalisée définit un volume interne, au sein duquel est destiné à être inséré un ou plusieurs greffons d'os spongieux ou un substitut osseux, destiné à permettre la The cage thus produced defines an internal volume, into which is intended to be inserted one or more spongy bone grafts or a bone substitute, intended to allow the
fusion effective entre les deux corps vertébraux entre lesquels est inséré ledit implant. effective fusion between the two vertebral bodies between which said implant is inserted.
A cet effet, l'expansion de l'os spongieux s'effectue au niveau de toute la périphérie de la fente, sauf au niveau de l'ouverture traversante (5) définie au niveau de la zone de jonction (4), o cette ouverture est comblée, à tout le moins en partie par la vis (12) For this purpose, the expansion of the cancellous bone takes place at the level of the entire periphery of the slot, except at the level of the through opening (5) defined at the level of the junction zone (4), where this opening is filled, at least in part by the screw (12)
décrite ci-après plus en détail.described below in more detail.
Selon une caractéristique de l'invention, les deux branches, respectivement (2) et (3) présentent au niveau de leur face interne respective, un filetage partiel (8) s'étendant sensiblement sur partie de leur longueur, et s'interrompant un peu en deçà de leur extrémité libre en formant une goulotte (14) exempte donc de tout filetage, et faisant According to a characteristic of the invention, the two branches, respectively (2) and (3) have at their respective internal face, a partial thread (8) extending substantially over part of their length, and interrupting a slightly below their free end by forming a chute (14) therefore free of any thread, and making
seulement fonction de guidage d'une vis (12) décrite plus en détail ciaprès. only guide function of a screw (12) described in more detail below.
Ce filetage ainsi défini, est destiné à coopérer avec une vis (12), de pas de vis correspondant. Cette vis (12) est insérée au niveau de l'ouverture (5) de la zone de jonction (4), après la mise en place de l'implant inter-somatique au niveau de l'espace inter-vertébral souhaité. Cette vis vient donc mordre dans le filetage (6) de la zone de jonction (4). La tête de vis est munie soit d'une fente, soit d'une croix, soit encore d'un volume hexagonale (13), afin de pouvoir coopérer ave un tournevis ou une clef six pans. On conçoit aisément que lors du vissage de cette vis, faisant également fonction de bouchon, elle progresse sur le filetage partiel (8), et est en outre guidée par la goulotte (14), ladite vis (12) présentant alors une portion terminale (15) exempte de tout filetage, afin de coopérer librement avec la goulotte (14). Au fur et à mesure de sa progression, elle induit l'écartement progressif des branches (2) et (3) l'une de l'autre. De la sorte, le vissage de la vis au niveau de ce filetage transforme progressivement l'action cyphosante de l'implant en action lordosante, typiquement dans une gamme comprise entre -5 à +80 par rapport à la parallèle moyenne définie par l'orientation This thus defined thread is intended to cooperate with a screw (12), of corresponding screw pitch. This screw (12) is inserted at the opening (5) of the junction area (4), after the inter-somatic implant has been placed at the desired inter-vertebral space. This screw therefore comes to bite into the thread (6) of the junction zone (4). The screw head is provided either with a slot, or with a cross, or else with a hexagonal volume (13), in order to be able to cooperate with a screwdriver or a hexagon key. It is easy to see that when this screw is screwed, also acting as a plug, it progresses on the partial thread (8), and is further guided by the chute (14), said screw (12) then having a terminal portion ( 15) free of any thread, in order to cooperate freely with the chute (14). As it progresses, it induces the progressive separation of the branches (2) and (3) from one another. In this way, the screwing of the screw at the level of this thread progressively transforms the kyphogenic action of the implant into lordosing action, typically in a range between -5 to +80 relative to the mean parallel defined by the orientation
des deux plateaux au niveau desquels l'implant est inséré. of the two plates at the level of which the implant is inserted.
On conçoit dès lors tout l'intérêt de l'implant inter-somatique de l'invention, dans la mesure o en fonction de la pathologie rencontrée, le chirurgien est à même d'utiliser un implant inter-somatique standard, qu'il règle en fonction de l'action souhaitée dudit We can therefore see the whole point of the inter-somatic implant of the invention, insofar as depending on the pathology encountered, the surgeon is able to use a standard inter-somatic implant, which he adjusts depending on the desired action of said
implant par simple vissage plus ou moins prononcé de la vis au sein du filetage (8). implant by simple more or less pronounced screwing of the screw within the thread (8).
En outre, afin de s'assurer qu'il n'y a pas modification du réglage souhaité par le praticien, on procède à la destruction du filetage (8) situé en amont de la vis par rapport au sens du vissage, par exemple à l'aide d'un outil tranchant Ce faisant, la vis ne peut plus reculer. Parallèlement, elle ne peut plus avancer, compte-tenu de la pression exercée par les deux branches, respectivement supérieure et In addition, in order to ensure that there is no modification of the adjustment desired by the practitioner, the thread (8) located upstream of the screw relative to the direction of screwing is destroyed, for example at using a sharp tool In doing so, the screw can no longer move back. At the same time, it can no longer move forward, given the pressure exerted by the two branches, respectively upper and
inférieure, sur la vis, et de par sa configuration cyphosante par défaut. lower, on the screw, and by its default kyphosic configuration.
Selon l'invention, la zone (5) de la face postérieure de la cage est relativement réduite au regard de cette face postérieure. De la sorte, lors de la mise en place de l'implant, et surtout lors de l'opération de vissage, le praticien peut visualiser la progression de la cage dans l'espace inter-vertébral sans être gêné par l'ancillaire de pose, optimisant According to the invention, the area (5) of the rear face of the cage is relatively small with regard to this rear face. In this way, during the placement of the implant, and especially during the screwing operation, the practitioner can visualize the progression of the cage in the inter-vertebral space without being hampered by the ancillary of placement , optimizing
ainsi les conditions de sécurité.thus the security conditions.
Corollairement, outre l'action dynamique possible de l'implant, l'invention vise As a corollary, in addition to the possible dynamic action of the implant, the invention aims
également à optimiser son profil anatomique. also to optimize its anatomical profile.
Ainsi, les faces externes des branches respectivement supérieure et inférieure sont bombées, afin de permettre une meilleure adaptation au profil concave des plateaux Thus, the external faces of the upper and lower branches respectively are curved, in order to allow a better adaptation to the concave profile of the plates
des corps vertébraux au niveau desquels elles sont destinés à exercer une pression. vertebral bodies at the level of which they are intended to exert pressure.
Plus spécifiquement, elles présentent un double bombage, c'est à dire à la fois selon More specifically, they have a double bending, that is to say both according to
leur dimension principale, mais également selon une direction perpendiculaire à celleci, ainsi qu'on peut bien l'observer en relation avec les figures 2 à 4. their main dimension, but also in a direction perpendicular to this, as can be seen in relation to Figures 2 to 4.
Ce bombement est légèrement dissymétrique, et est plus prononcé au niveau de la zone interne de l'implant. A cet égard, la hauteur de l'implant en zone interne est This bulging is slightly asymmetrical, and is more pronounced in the internal area of the implant. In this regard, the height of the implant in the internal area is
légèrement supérieure à celle en zone externe. slightly higher than in the external area.
Le sommet du bombement est avantageusement situé à la jonction du tiers postérieur et des deux tiers antérieurs, respectivement des faces supérieure et inférieure des The top of the bulge is advantageously located at the junction of the posterior third and the anterior two thirds, respectively of the upper and lower faces of the
branches supérieure et inférieure. upper and lower branches.
Par ailleurs, la convexité de la branche inférieure est légèrement inférieure à celle de la In addition, the convexity of the lower branch is slightly lower than that of the
branche supérieure.upper branch.
Ce faisant, l'écartement des branches (2, 3) résultant de l'introduction de la vis (12) au sein de la cage induit un appui desdites branches contre les plateaux vertébraux respectifs sensiblement au niveau de toute leur surface, respectivement inférieure et supérieure, et non limité à leur seule extrémité, favorisant de fait le phénomène de In doing so, the spacing of the branches (2, 3) resulting from the introduction of the screw (12) within the cage induces a support of said branches against the respective vertebral plates substantially at the level of their entire surface, respectively lower and superior, and not limited to their only end, favoring in fact the phenomenon of
fusion recherchée.fusion sought.
Parallèlement, compte-tenu que ce type d'implant est appelé à fonctionner par paires, ainsi qu'on l'a représenté en figure 7, c'est à dire un implant coopérant avec chacune des cavités du plateau du corps vertébral, l'une des faces latérales présente une surface réduite en médiane, permettant d'obtenir une surface de contact prédéterminée et choisie, avec un deuxième implant symétrique destiné à venir s'insérer également au niveau de l'espace inter-vertébral. On définit ainsi un implant gauche et un implant droit, les deux implants étant symétriques l'un de l'autre par rapport à leur surface latérale destinée à venir en contact l'une de l'autre lors de la mise en place desdits At the same time, given that this type of implant is called upon to operate in pairs, as shown in FIG. 7, that is to say an implant cooperating with each of the cavities of the plateau of the vertebral body, the one of the lateral faces has a reduced surface in the middle, making it possible to obtain a predetermined and chosen contact surface, with a second symmetrical implant intended to also be inserted at the level of the inter-vertebral space. A left implant and a right implant are thus defined, the two implants being symmetrical to each other with respect to their lateral surface intended to come into contact with one another during the positioning of said implants.

On dispose ainsi d'un implant inter-somatique intervertébral cumulant à la fois une fonction anatomique et une fonction dynamique, simplifiant le travail du praticien, tout We thus have an intervertebral intervertebral implant combining both an anatomical and a dynamic function, simplifying the work of the practitioner, while
en fonctionnant à partir d'éléments standards. by operating from standard elements.
Plus spécifiquement, la forme particulière de l'implant conforme à l'invention, plus particulièrement adaptée à l'anatomie des plateaux vertébraux, permet d'augmenter la surface de contact avec ceux-ci, de disposer d'une meilleure répartition des More specifically, the particular shape of the implant according to the invention, more particularly adapted to the anatomy of the vertebral plates, makes it possible to increase the contact surface with these, to have a better distribution of the
contraintes, et partant, d'aboutir à une meilleure fusion. constraints, and therefore, to achieve a better merger.
De plus, de par cette forme mieux adaptée anatomiquement, l'implant devient autostable, et ne nécessite donc pas d'ostéosynthèse postérieure de stabilisation, ce qui In addition, due to this better anatomically adapted shape, the implant becomes self-supporting, and therefore does not require posterior stabilization osteosynthesis, which
n'était pas le cas avec les implants de l'art antérieur. was not the case with prior art implants.
io En outre, le caractère dynamique de l'implant conforme à l'invention permet outre une meilleure adaptation de celui-ci à la pathologie du patient, également de réduire les risques d'éventuelles déformations type cyphose, hyperlordose, scoliose, spondylolisthésis. Enfin, de par son anatomie et son caractère dynamique, l'implant de l'invention assure une fonction de calage, selon une orientation différenciée, conduisant à une stabilité intrinsèque. - In addition, the dynamic nature of the implant according to the invention makes it possible, in addition to better adaptation of the latter to the patient's pathology, also to reduce the risks of possible deformations such as kyphosis, hyperlordosis, scoliosis, spondylolisthesis. Finally, due to its anatomy and dynamic nature, the implant of the invention provides a wedging function, according to a differentiated orientation, leading to intrinsic stability. -
