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.

Description

DlsDosItlf de fixation d'une prothèse liaamentaire.  DlsDosItlf for fixing a liaental prosthesis.

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

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. Ce type de prothèses à pour but de stabiliser la flexion - extension et la rotation. Généralement, les extrémités des ligaments sont cousus en huit, entre les apophyses épineuses. It is known to use, to ensure intervertebral compression of prostheses associating ligaments with rigid or flexible wedges, generally disposed between the spinous processes of the vertebrae. This type of prosthesis aims to stabilize flexion - extension and rotation. Generally, the ends of the ligaments are sewn in 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 conception, the problem which the invention proposes to solve is to improve the fixation of the ligaments, at the level of the spines.

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 shock absorbing element placed between two thorns, said element being shaped for the passage 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 able to be engaged and positioned in holes formed in the thickness of the spinous processes, said means being shaped for the passage of fixing members cooperating with arrangements which have the free ends of the 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 resolve the problem posed of securing the ligaments at the thorny level, the means consist of two complementary nestable parts.

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, one of the ends of the bodies being extended by a facial support flange 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 posed of securing the ligaments, the arrangements of the latter consist of eyelets crimped at the end of said ligaments.

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

L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels:
La figure 1 est une vue en perspective des éléments engagés dans les épineuses pour la fixation des ligaments.The invention is set out below in more detail using the appended drawings, in which:
Figure 1 is a perspective view of the elements engaged in the thorny for fixing the ligaments.

La figure 2 est une vue en plan d'un ligament équipé des agencements de fixation. FIG. 2 is a plan view of a ligament equipped with the fixing 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. FIG. 4 is a plan view corresponding to FIG. 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). La cale (1) est conformée pour le pasage dans des conditions déterminées de ligaments artificiels (2). Plus particulièrement, la cale (1) est réalisée dans une matière semi rigide, sous forme, par exemple, d'un corps cylindrique. La cale (1) est percée de part en part pour le passage des ligaments (2). In a known manner, the prosthetic element comprises a damping element (1), constituting a wedge capable of being disposed between two spinous processes (El) and (E2). The wedge (1) is shaped for the passage under determined conditions of artificial ligaments (2). More particularly, the wedge (1) is made of a semi-rigid material, in the form, for example, of a cylindrical body. The wedge (1) is drilled right through for the passage of the ligaments (2).

Avantageusement, la cale est percée pour le passage, d'une manière croisée, de deux ligaments. Cette cale (2) peut, de manière connue, présenter différentes hauteurs pour caler les vertèbres, en distraction réduite. Advantageously, the wedge is pierced for the passage, in a crossed manner, of two ligaments. 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, capable of securing the ligaments (2), has means designed to be engaged and positioned in holes (T) formed in the thickness of the thorny plants.

Comme le montre la figure 1, ces moyens sont constitués par deux parties complémentaires (3) et (4). Chaque partie présente un corps cylindrique creux (3a) (4a), lesquels corps étant emboitables.As shown in Figure 1, these means are constituted by two complementary parts (3) and (4). Each part has a hollow cylindrical body (3a) (4a), which bodies 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. Après emboitement, les deux parties (3) et (4) constituent un élément ayant très sensiblement la forme d'un diabolo. In addition, one of the ends of each of the bodies (3a) and (4a) is extended by a facial support flange (3b) and (4b), so as to ensure centering of the assembly of the two parts ( 3) and (4), after fitting into the corresponding hole of the spinous process. After interlocking, the two parts (3) and (4) constitute an element having very substantially the shape of a diabolo.

Ces dispositions permettent donc d'enserrrer la section des épineuses. These provisions therefore allow to enclose the thorny 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 characteristic, after introduction of the ligaments (2) into the wedge (1), the ends (2a) and (2b) of each of the ligaments, are equipped with eyelets (5) which, advantageously, are crimped at the end of said extremities.

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). Ces organes d'assemblage sont constitués par un système comprenant un boulon (6), deux écrous (7) (8) et une goupille (9). The ligaments are fixed relative to the thorns by means of assembly members, cooperating with the eyelets (5) and engaged in the hollow bodies (3a) and (4a) of the parts (3) and (4). 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. The operative technique should be analyzed, 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. 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). Les colerettes (3b) et (4b) sont en appui sur les faces correspondantes des épineuses (El) et (E2). The operator first pierces the thorny plants very appreciably in their middle part. It is then possible to engage, in the holes (T) made, the parts (3) and (4) which are fitted at their hollow body (3a) and (4a). The flanges (3b) and (4b) are supported on the corresponding faces of the thorns (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 wedge (1), between the thorns considered (El) and (E2) and engages the test ligaments in the wedge (1), to measure their length.

Après avoir pris ces mesures, les ligaments définitifs (2) sont introduits dans la cale (1) et équipés en bout des oeillets (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). La goupille (9) assure le blocage en translation du système écrou contre-écrou en cas de blocage accidentel. After taking these measures, the final ligaments (2) are introduced into the wedge (1) and fitted at the end of the eyelets (5). It then suffices to engage the bolt (6) through the eyelets and the nested parts (3) and (4), and to ensure the assembly by means of the nut and lock nut (7) and (8). The pin (9) locks in translation the nut-lock nut system in the event of accidental blocking.

Bien évidemment, le dispositif de fixation tel que décrit, peut etre répété sur plusieurs étages, par exemple, pour trois épineuses. Dans ce cas, le même système de boulon est utilisé pour deux montages successifs. Le boulon reçoit, en superposition, les extrémités des ligaments consécutifs. Obviously, the fixing device as described, can be repeated over several stages, for example, for three thorns. In this case, the same bolt system is used for two successive assemblies. The bolt receives, in superposition, the ends of the consecutive 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 cushioning shim and of the ligaments is not described in detail because it is perfectly known to a person skilled in the art, being moreover capable of being the subject of different variant embodiments, depending on the case. pathological to be treated.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle le meilleur contrôle de la rotation axiale.  The advantages clearly emerge from the description, in particular it emphasizes and recalls the better control of the axial rotation.
