Abstract

A cylindrical or similar shock-absorbing component (1) is located between two adjacent vertebral projections (E1,E2) to receive artificial ligaments which pass through its central aperture. Eyelet components (3,4) are located on either side of holes formed in the vertebral apophyses, to receive transverse fasteners (6) to which the end portions (5) of the ligaments are attached. The eyelets each consist of a pair of washers, with interengaging flanges extending inwardly of the apophyse hole to engage each other. The end portions of the ligaments include loops which engage over a bolt or similar fastener passed through the passage defined by the interengaging flanges of the washers.

L'invention se rattache au secteur technique des prothèses intervertébrales. The invention relates to the technical sector of the intervertebral prosthesis.

II est connu d'utiliser, pour assurer une contention intervertébrale des prothèses associant des ligaments à des cales rigides ou souples, généralement disposés entre les apophyses épineuses des vertèbres. It is known to use, to ensure containment intervertebral prosthesis combining ligaments in rigid or flexible shims generally located between the spinous processes of the vertebrae. Ce type de prothèses à pour but de stabiliser la flexion - extension et la rotation. This type of prostheses designed to stabilize the flexion - extension and rotation. Généralement, les extrémités des ligaments sont cousus en huit, entre les apophyses épineuses. Typically, the ends of the ligaments are sewn into eight, between the spinous processes.

A partir de cette conception de base, le problème que se propose de résoudre l'invention, est d'améliorer la fixation des ligaments, au niveau des épineuses. From this basic design, the problem is solved by the invention is to improve the attachment of ligaments in thorny.

Pour résoudre un tel problème, il a été conçu et mis au point un dispositif de fixation d'une prothèse ligamentaire comprenant un élément amortisseur placé entre deux épineuses, ledit élément étant conformé pour le pasage de ligaments artificiels. To solve such a problem, it has been designed and developed a device for fixing a ligament prosthesis comprising a damper element arranged between two spinous, said element being shaped to the pasage of artificial ligaments.

Selon l'invention, le dispositif comprend des moyens aptes à être engagés et positionnés dans des trous formés dans l'épaisseur des apophyses épineuses, lesdits moyens étant conformés pour le passage d'organes de fixation coopérant avec des agencements que présentent les extrémités libres des ligaments. According to the invention, the device comprises means adapted to be engaged and positioned in holes formed in the thickness of the spinous processes, said means being shaped for the passage of fastening members cooperating with fittings that have the free ends of ligaments.

Pour résoudre le problème posé d'assurer la fixation des ligaments au niveau des épineuses, les moyens sont constitués par deux parties complémentaires emboitables. To solve the problem of ensuring the attachment of ligaments at thorny, the means are formed by two complementary parts which fit together.

Chaque partie présente un corps cylindrique creux, les corps des deux parties étant emboitables, I'une des extrémités des corps étant prolongée par une collerette d'appui faciale sur une partie correspondante de l'apophyse épineuse. Each part has a hollow cylindrical body, the bodies of the two parts being nestable, I'une the ends of the body being extended by a collar face bearing on a corresponding part of the spinous process.

Pour résoudre le problème posé d'assurer la fixation des ligaments, les agencements de ces derniers sont constitués par des oeillets sertis en bout desdits ligaments. To solve the problem of ensuring the attachment of ligaments, these arrangements consist of eyelets crimped end said ligaments.

Les organes d'assemblage sont constitués par un système qui comprend un boulon, deux écrous et une goupille. The fasteners are constituted by a system which includes a bolt, a pin and two nuts.

L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels: The invention is explained below in more detail in the accompanying drawings, wherein:
La figure 1 est une vue en perspective des éléments engagés dans les épineuses pour la fixation des ligaments. Figure 1 is a perspective view of the elements involved in the spinous for attachment of ligaments.

La figure 2 est une vue en plan d'un ligament équipé des agencements de fixation. Figure 2 is a plan view of a ligament with fastening arrangements.

La figure 3 est une vue en coupe longitudinale montrant la mise en place du dispositif selon l'invention. Figure 3 is a longitudinal sectional view showing the installation of the device according to the invention.

La figure 4 est une vue en plan correspondant à la figure 3. Figure 4 is a plan view corresponding to Figure 3.

D'une manière connue, I'élément prothétique comprend un élément amortisseur (1), constituant une cale apte à être disposée entre deux apophyses épineuses (El) et (E2). In a known manner, I'élément prosthetic comprises a damping element (1), forming a wedge adapted to be disposed between two spinous processes (El) and (E2). La cale (1) est conformée pour le pasage dans des conditions déterminées de ligaments artificiels (2). The wedge (1) is shaped to the pasage in specified conditions of artificial ligaments (2). Plus particulièrement, la cale (1) est réalisée dans une matière semi rigide, sous forme, par exemple, d'un corps cylindrique. More particularly, the shim (1) is performed in a semi-rigid material, as, for example, of a cylindrical body. La cale (1) est percée de part en part pour le passage des ligaments (2). The wedge (1) is pierced right through for the passage of the ligaments (2).

Avantageusement, la cale est percée pour le passage, d'une manière croisée, de deux ligaments. Advantageously, the wedge is pierced for the passage, in a crosswise manner, two ligaments. Cette cale (2) peut, de manière connue, présenter différentes hauteurs pour caler les vertèbres, en distraction réduite. This wedge (2) can, in known manner, have different heights to wedge the vertebrae, in reduced distraction.

Selon l'invention, le dispositif, apte à assurer la fixation des ligaments (2), présente des moyens conformés pour être engagés et positionnés dans des trous (T) formés dans l'épaisseur des épineuses. According to the invention, the device, suitable for ensuring the attachment of the ligaments (2) has means shaped to be engaged and positioned in holes (T) formed in the thickness of the spinous.

Comme le montre la figure 1, ces moyens sont constitués par deux parties complémentaires (3) et (4). As shown in Figure 1, these means are constituted by two complementary portions (3) and (4). Chaque partie présente un corps cylindrique creux (3a) (4a), lesquels corps étant emboitables. Each part has a hollow cylindrical body (3a) (4a), which body being nestable.

En outre, I'une des extrémités de chacun des corps (3a) et (4a) est prolongée par une colerette d'appui faciale (3b) et (4b), de manière à assurer un centrage de l'ensemble des deux parties (3) et (4), après emboitement dans le trou correspondant de l'apophyse épineuse. In addition, I'une the ends of each of the body (3a) and (4a) is extended by a bearing face rim (3b) and (4b), so as to ensure centering of the assembly of two parts ( 3) and (4), after fitting into the corresponding hole of the spinous process. Après emboitement, les deux parties (3) et (4) constituent un élément ayant très sensiblement la forme d'un diabolo. After nesting, the two parts (3) and (4) constituting an element having very substantially the shape of a diabolo.

Ces dispositions permettent donc d'enserrrer la section des épineuses. These provisions allow the thorny enserrrer section.

Selon une autre caractéristique, après introduction des ligaments (2) dans la cale (1), les extrémités (2a) et (2b) de chacun des ligaments, sont équipées d'oeillets (5) qui, avantageusement, sont sertis en bout desdites extrémités. According to another feature, after introduction of the ligaments (2) in the shim (1), the ends (2a) and (2b) of each of the ligaments, are equipped with eyelets (5) which, advantageously, are crimped end of said ends.

La fixation des ligaments par rapport aux épineuses s'effectue au moyen d'organes d'assemblage, coopérant avec les oeillets (5) et engagés dans les corps creux (3a) et (4a) des parties (3) et (4). Fixing ligaments compared to the spinous is effected by means of connecting elements, cooperating with the lugs (5) and engaged in the hollow bodies (3a) and (4a) of the portions (3) and (4). Ces organes d'assemblage sont constitués par un système comprenant un boulon (6), deux écrous (7) (8) et une goupille (9). These assembly members are constituted by a system comprising a bolt (6), two nuts (7) (8) and a pin (9).

II convient d'analyser la technique opératoire, en fonction de la mise en oeuvre du dispositif selon l'invention. It should analyze the operative technique, depending on the implementation of the device according to the invention.

L'opérateur perce, dans un premier temps, les épineuses très sensiblement dans leur partie médiane. The operator drills, at first, the spinous very substantially in their median part. II est alors possible d'engager, dans les trous (T) effectués, les parties (3) et (4) qui sont emboitées au niveau de leur corps creux (3a) et (4a). It is then possible to engage in the holes (T) carried out, the parts (3) and (4) which are nested in their hollow bodies (3a) and (4a). Les colerettes (3b) et (4b) sont en appui sur les faces correspondantes des épineuses (El) et (E2). The colerettes (3b) and (4b) are supported on the corresponding faces of the spinous (El) and (E2).

L'opérateur met ensuite en place la cale amortisseur (1), entre les épineuses considérées (El) et (E2) et engage les ligaments d'essai dans la cale (1), pour mesurer leur longueur. The operator then sets up the damper shim (1), between the spinous considered (El) and (E2) and engages the test ligaments in the bilge (1), for measuring their length.

Après avoir pris ces mesures, les ligaments définitifs (2) sont introduits dans la cale (1) et équipés en bout des oeillets (5). After these steps, the final ligaments (2) are introduced into the cradle (1) fitted at the end eyelets (5). Il suffit alors d'engager le boulon (6) au travers des oeillets et des parties emboitées (3) et (4), et d'assurer l'assemblage au moyen des écrou et contre-écrou (7) et (8). It is sufficient to engage the bolt (6) through the eyelets and nested parts (3) and (4) and ensure the assembly by means of nut and against nut (7) and (8). La goupille (9) assure le blocage en translation du système écrou contre-écrou en cas de blocage accidentel. The pin (9) provides the locking in translation of the nut against nut system in case of accidental blocking.

Bien évidemment, le dispositif de fixation tel que décrit, peut etre répété sur plusieurs étages, par exemple, pour trois épineuses. Of course, the fastening device as described, can be repeated on several floors, for example, for three spiny. Dans ce cas, le même système de boulon est utilisé pour deux montages successifs. In this case, the same bolt system is used for two successive fixtures. Le boulon reçoit, en superposition, les extrémités des ligaments consécutifs. Receives the bolt, in superposition, the consecutive ends of the ligaments.

La forme de réalisation de la cale amortisseur et des ligaments n'est pas décrite en détail car parfaitement connue pour un homme du métier, en étant susceptible, par ailleurs, de faire l'objet de différentes variantes d'exécution, en fonction du cas pathologique à traiter. The embodiment of the damper shim and ligaments is not described in detail as well known for a skilled person, by being capable, moreover, be subject to different variants of execution, depending on the case disease to treat.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle le meilleur contrôle de la rotation axiale. The advantages are apparent from the description, in particular better control of axial rotation is emphasized and recalled.
