Description
DisPositif Dour la réduction de fractures.Device for the reduction of fractures.
La présente invention concerne un dispositif pour la réduction de fractures, en particulier de fractures du grand trochanter.The present invention relates to a device for reducing fractures, in particular fractures of the greater trochanter.
Les fractures per-trochantériennes, dont les traits de fractures intéressent la partie supérieure du grand trochanter peuvent présenter différents types anatomiques basicervicale, per-trochantérienne comminutive, soustrochantérienne sont aujourd'hui traitées par un dispositif vis-plaque. Ce dispositif est constitué d'une plaque maintenue fixe, en appui contre la face extérieure du fémur dont elle épouse le profil, grâce à des vis corticales pénétrant dans des ouvertures réparties le long de son axe longitudinal, cette plaque étant prolongée à son extrémité supérieure par un fût généralement cylindrique s'étendant dans une direction qui forme un angle obtus avec l'axe longitudinal de ladite plaque de manière à pénétrer par implantation per-trochantérienne ou sous-trochantérienne jusque dans le col du fémur. Un clou ou une vis passent dans ce fût pour s'ancrer dans le col et la tête du fémur.Pertrochanteric fractures, the fracture lines of which interest the upper part of the greater trochanter, can present different anatomical types basicervical, comminuted pertrochanteric, subtrochanteric are today treated by a screw-plate device. This device consists of a plate kept fixed, pressing against the external face of the femur whose profile it follows, thanks to cortical screws penetrating into openings distributed along its longitudinal axis, this plate being extended at its upper end. by a generally cylindrical barrel extending in a direction which forms an obtuse angle with the longitudinal axis of said plate so as to penetrate by per-trochanteric or sub-trochanteric implantation as far as the neck of the femur. A nail or a screw pass in this barrel to anchor in the neck and the head of the femur.
Ce dispositif est performant et assure une contention parfaite lorsque le trait de facture est inférieur au point d'insertion supérieur de la vis-plaque. Par contre, lorsque le trait atteint l'endroit de pénétration ou siège au-dessus de lui, il se produit un déplacement secondaire dans le temps de la diaphyse vers l'intérieur avec protrusion du clou et ascension ou déplacement en dehors du grand trochanter.This device is efficient and ensures perfect compression when the invoice line is less than the upper insertion point of the screw-plate. On the other hand, when the line reaches the point of penetration or seat above it, there occurs a secondary displacement in time of the diaphysis inwards with protrusion of the nail and ascent or displacement outside the greater trochanter.
Un autre dispositif assurant le maintien du grand trochanter est décrit dans le brevet EP-A-217.317. Ce dispositif est constitué d'une plaque conformée pour épouser le fémur sur une grande partie de sa longueur à partir du grand trochanter, cette plaque comportant un alésage traversant fileté permettant l'insertion d'une broche susceptible de pénétrer jusque dans la tête du fémur, cette broche étant démontable par simple dévissage lorsque l'os est consolidé. Un tel dispositif, en raison de la hauteur de la plaque qui doit s'adapter parfaitement au profil de l'os, semble en pratique peu applicable sans avoir à disposition une pluralité de plaques susceptibles de s'adapter à n'importe quelle morphologie. En outre, un tel dispositif nécessite un grand nombre de points d'ancrage augmentant les traumatismes et ne facilitant pas le travail du chirurgien.Another device ensuring the maintenance of the greater trochanter is described in patent EP-A-217,317. This device consists of a shaped plate to marry the femur over a large part of its length from the greater trochanter, this plate having a threaded through bore allowing the insertion of a pin capable of penetrating into the head of the femur , this pin being removable by simple unscrewing when the bone is consolidated. Such a device, because of the height of the plate which must adapt perfectly to the profile of the bone, seems in practice not very applicable without having available a plurality of plates capable of adapting to any morphology. In addition, such a device requires a large number of anchoring points increasing trauma and not facilitating the work of the surgeon.
Le but de la présente invention est donc de proposer un dispositif de réduction des fractures du grand trochanter constituant un perfectionnement du système vis-plaque connu a ce jour en supprimant l'inconvénient majeur de ce dernier, à savoir la dérive du grand trochanter par rapport au reste du fémur au cours du processus d'ostéosynthèse.The object of the present invention is therefore to propose a device for reducing fractures of the greater trochanter constituting an improvement of the screw-plate system known to date by eliminating the major drawback of the latter, namely the drift of the greater trochanter with respect to to the rest of the femur during the osteosynthesis process.
L'invention a pour objet à cet effet un dispositif pour la réparation, en particulier la réduction, de fractures comminutives du grand trochanter du type comprenant une visplaque constituée d'une plaque maintenue fixe en appui contre la face extérieure du fémur dont elle épouse le profil grâce à des vis corticales pénétrant dans des ouvertures réparties le long de son axe longitudinal, cette plaque étant prolongée à son extrémité supérieure par un fût généralement cylindrique s'étendant dans une direction qui forme un angle obtus avec l'axe longitudinal de ladite plaque de manière à pénétrer par implantation per-trochantérienne ou sous-trochantérienne jusque dans le col du fémur, et la tête du fémur, dans lequel il est ancré au moyen d'un clou ou d'une vis introduit par un alésage axial traversant dudit fût, caractérisé en ce qu'il comporte une plaque trochantérienne qui est intercalée entre la face extérieure du fémur et la plaque de l'ensemble visplaque, et est maintenue en appui contre l'os, d'une part par ledit ensemble vis-plaque dont la plaque présente un profil complémentaire de ladite plaque trochantérienne et dont le fût traverse au moins un logement ménagé dans la plaque, d'autre part par un prolongement de sa partie supérieure constituant au moins une branche formant crochet conformée pour épouser le profil du grand trochanter et se fixant par simple pression sur ce dernier de telle sorte qu'une ascension du trochanter par rapport au reste du fémur est impossible.The subject of the invention is to this end a device for repairing, in particular the reduction, of comminuted fractures of the greater trochanter of the type comprising a plate consisting of a plate held fixed in abutment against the external face of the femur which it marries profile thanks to cortical screws penetrating into openings distributed along its longitudinal axis, this plate being extended at its upper end by a generally cylindrical shaft extending in a direction which forms an obtuse angle with the longitudinal axis of said plate so as to penetrate by per-trochanteric or sub-trochanteric implantation into the neck of the femur, and the head of the femur, in which it is anchored by means of a nail or a screw introduced by an axial bore passing through said barrel , characterized in that it comprises a trochanteric plate which is interposed between the external face of the femur and the plate of the assembly visplate, and is held in abutment against the bone, on the one hand by said screw-plate assembly whose plate has a profile complementary to said trochanteric plate and whose barrel passes through at least one housing formed in the plate, on the other part by an extension of its upper part constituting at least one hook-shaped branch shaped to match the profile of the greater trochanter and fixing by simple pressure on the latter so that an ascent of the trochanter relative to the rest of the femur is impossible.
Selon une forme de réalisation préférée de l'invention, la plaque trochantérienne comporte un troisième point d'ancrage sur l'os du fémur constitué par un logement traversant, maintenu en regard d'un logement de l'ensemble vis-plaque destiné à recevoir une vis corticale au moyen de guides disposés en relief sur la face apparente de ladite plaque trochantérienne, lesdits guides empêchant tout pivotement de l'ensemble vis-plaque autour du fût formant pivot. En outre, pour parfaire l'ancrage, la plaque trochantérienne est prolongée dans sa partie supérieure par au moins deux branches formant crochet, lesdits crochets étant terminés par des griffes.According to a preferred embodiment of the invention, the trochanteric plate comprises a third anchor point on the bone of the femur constituted by a through housing, held facing a housing of the screw-plate assembly intended to receive a cortical screw by means of guides arranged in relief on the visible face of said trochanteric plate, said guides preventing any pivoting of the screw-plate assembly around the barrel forming a pivot. In addition, to perfect the anchoring, the trochanteric plate is extended in its upper part by at least two branches forming a hook, said hooks being terminated by claws.

La présente invention concerne un perfectionnement au dispositif vis-plaque couramment utilisé à ce jour pour réduire les fractures du grand trochanter. Il est rappelé que le grand trochanter 2 constitue l'une des parties du fémur 1 et jouxte en particulier le col de fémur 3 qui sépare le grand trochanter de la tête de fémur 4.The present invention relates to an improvement to the screw-plate device commonly used to date for reducing fractures of the greater trochanter. It is recalled that the greater trochanter 2 constitutes one of the parts of the femur 1 and adjoins in particular the neck of the femur 3 which separates the greater trochanter from the head of the femur 4.
Ce dispositif vis-plaque représenté aux figures 2A et 2B comporte une plaque 6 formée d'une seule pièce avec un fût 7, ensemble présentant un profil coudé. En effet, l'axe longitudinal yy' de la plaque 6 forme avec l'axe longitudinal xx' du fût un angle obtus a. Le fût 7 est implanté dans une position sous-trochantérienne ou per-trochantérienne et s'étend jusque dans le col du fémur 3, voire dans la tête de fémur 4, où il est maintenu immobilisé au moyen d'un clou ou d'une vis 8. Ce clou 8 est introduit par une extrémité de l'alésage traversant 10 du fût 7 pour faire saillie à son autre extrémité et s'immobiliser dans la tête de fémur 4. La partie plaque 6 de l'ensemble vis-plaque 5 comporte, pour parfaire cet ancrage sur le fémur, des perçages ou logements traversants 9 répartis le long de son axe longitudinal yy' et destinés à permettre l'insertion de vis dites corticales dans le fémur dans la diaphyse de l'os.This screw-plate device shown in FIGS. 2A and 2B comprises a plate 6 formed in one piece with a barrel 7, all having an angled profile. Indeed, the longitudinal axis yy 'of the plate 6 forms with the longitudinal axis xx' of the barrel an obtuse angle a. The barrel 7 is implanted in a sub-trochanteric or per-trochanteric position and extends as far as the neck of the femur 3, or even into the head of the femur 4, where it is kept immobilized by means of a nail or a screw 8. This nail 8 is inserted through one end of the through bore 10 of the barrel 7 to project at its other end and immobilize in the femur head 4. The plate part 6 of the screw-plate 5 assembly includes, to perfect this anchoring on the femur, through holes or housings 9 distributed along its longitudinal axis yy 'and intended to allow the insertion of so-called cortical screws in the femur in the shaft of the bone.
Pour parfaire la contention de l'os par rapport à ce dispositif vis-plaque connu, on insère entre la plaque 6 de la vis-plaque et la face extérieure du fémur 1 une plaque dite trochantérienne 11 dont un mode de réalisation est représenté aux figures 3A et 3B. Cette plaque 11 est conformée de manière à s'adapter parfaitement d'une part à la surface extérieure du fémur, d'autre part à la face intérieure de la plaque 6. La plaque 6 présentant une face interne concave; il en est de même pour la plaque trochantérienne 11. C'est cette forme qui s'adapte le mieux au profil externe du fémur. Cette plaque trochantérienne 11 est maintenue en appui contre la face externe du fémur grâce à des points de fixation disposés en plusieurs endroits. La plaque trochantérienne est tout d'abord maintenue par le fût 7 de l'ensemble vis-plaque 5 qui traverse un perçage traversant 12 ménagé sur ladite plaque trochantérienne 11 avant de pénétrer dans le fémur. De ce fait, en raison du coude que forme le fût 7 avec la plaque 6, la plaque 6 vient maintenir par appui la plaque trochantérienne 12 contre la face externe du fémur. Ce logement traversant 12 de réception du fût 7 ménagé dans la plaque trochantérienne 11 affecte une forme ovoïde élargie dans sa partie inférieure pour permettre l'introduction et le positionnement de l'ensemble vis-plaques 5 quelconques. En effet, selon le type de l'ensemble vis-plaques utilisées, l'angle a entre la plaque et le fût varie.To perfect the compression of the bone with respect to this known screw-plate device, between the plate 6 of the screw-plate and the external face of the femur 1 is inserted a so-called trochanteric plate 11, an embodiment of which is shown in the figures. 3A and 3B. This plate 11 is shaped so as to adapt perfectly on the one hand to the external surface of the femur, on the other hand to the internal face of the plate 6. The plate 6 having a concave internal face; it is the same for the trochanteric plate 11. It is this shape which best adapts to the external profile of the femur. This trochanteric plate 11 is held in abutment against the external face of the femur by means of fixing points arranged in several places. The trochanteric plate is first of all held by the barrel 7 of the screw-plate assembly 5 which passes through a through bore 12 formed on said trochanteric plate 11 before entering the femur. Therefore, due to the elbow formed by the barrel 7 with the plate 6, the plate 6 comes to hold by pressing the trochanteric plate 12 against the external face of the femur. This through housing 12 for receiving the barrel 7 formed in the trochanteric plate 11 has an ovoid shape enlarged in its lower part to allow the introduction and positioning of any screw-plate assembly 5. Indeed, depending on the type of screw-plate assembly used, the angle a between the plate and the barrel varies.
Un deuxième point d'ancrage de la plaque trochantérienne 11 sur le fémur est situé au niveau du grand trochanter de manière à assurer une liaison per-trochantérienne. Ce point d'ancrage est réalisé au moyen de griffes 15 dont est pourvue la plaque 11. Ces griffes 15 sont disposées à l'extrémité de branches 14 ménagées dans la partie supérieure de la plaque trochantérienne. Ces branches 14 sont des prolongements de la partie supérieure de la plaque trochantérienne 11. Les griffes 15 qui, dans l'exemple représenté à la figure 3B, affectent de profil une forme triangulaire, permettent de maintenir le grand trochanter 2 solidaire du reste du fémur 1 par simple pression lors du serrage des autres moyens de fixation de ladite plaque trochantérienne 11. En effet, ces griffes passent facilement à travers l'insertion du vaste externe au niveau de la crête du grand trochanter 2 avant d'être comprimées par la vis inférieure.A second anchor point of the trochanteric plate 11 on the femur is located at the level of the greater trochanter so as to ensure a per-trochanteric connection. This anchoring point is produced by means of claws 15 which is provided with the plate 11. These claws 15 are arranged at the end of branches 14 formed in the upper part of the trochanteric plate. These branches 14 are extensions of the upper part of the trochanteric plate 11. The claws 15 which, in the example shown in FIG. 3B, have a triangular shape in profile, allow the greater trochanter 2 to be held integral with the rest of the femur 1 by simple pressure when tightening the other means for fixing said trochanteric plate 11. In fact, these claws easily pass through the insertion of the large external at the crest of the large trochanter 2 before being compressed by the screw lower.
Le troisième point d'ancrage de la plaque trochantérienne 11 sur le fémur 1 est localisé dans la partie inférieure de la plaque trochantérienne et permet une solidarisation dans la zone corticale. Ce troisième point d'ancrage est constitué par un logement traversant 13 disposé dans la partie inférieure de la plaque trochantérienne 11 le long de son axe longitudinal.The third anchor point of the trochanteric plate 11 on the femur 1 is located in the lower part of the trochanteric plate and allows a connection in the cortical area. This third anchor point is constituted by a through housing 13 disposed in the lower part of the trochanteric plate 11 along its longitudinal axis.
Ce logement traversant 13 est maintenu en regard d'un logement 9 de l'ensemble vis-plaque destiné à recevoir une vis corticale au moyen de guides 16 disposés en relief sur la face apparente de la plaque trochantérienne 11, lesdits guides 16 empêchant tout pivotement de l'ensemble vis-plaque autour du fût formant pivot de part et d'autre de la plaque 11. En conséquence, ces guides, constitués par deux ailes venant en appui de part et d'autre des bords latéraux de la partie plaque 6 de l'ensemble vis-plaque, permettent de maintenir en alignement constant l'ensemble vis-plaque avec la plaque.This through housing 13 is held opposite a housing 9 of the screw-plate assembly intended to receive a cortical screw by means of guides 16 arranged in relief on the visible face of the trochanteric plate 11, said guides 16 preventing any pivoting. of the screw-plate assembly around the barrel forming a pivot on either side of the plate 11. Consequently, these guides, constituted by two wings coming to bear on either side of the lateral edges of the plate part 6 of the screw-plate assembly, allow the screw-plate assembly to be kept in constant alignment with the plate.
L'invention ne se limite pas aux formes de réalisation précitées mais englobe au contraire un grand nombre d'autres modes de réalisation restant dans le cadre de l'invention. The invention is not limited to the abovementioned embodiments but on the contrary encompasses a large number of other embodiments remaining within the scope of the invention.
