Abstract

The assembly has a group of spindles, where each spindle is alternately associated to oblong cones to form a modular above-knee prosthesis with a constant cervico-diaphyseal angle (alpha). Each spindle is different from other spindles by its longitudinal dimension. Each cone is different from other cones by its longitudinal dimension. A hemispherical cavity (10) of a modular collar (11) of each spindle receives an impaction tool for impacting the prosthesis in an axis (A1). A cylindrical threaded passage (9) receives a threaded tool to withdraw the prosthesis after withdrawing the cones.

Description

FAMILLE D'ÉLÉMENTS DE PROTHESES FEMORALES MODULAIRES DOMAINE TECHNIQUE DE L'INVENTION FAMILY OF ELEMENTS OF MODULAR FEMORAL PROSTHESES TECHNICAL FIELD OF THE INVENTION

[1] L'invention se rapporte à une famille d'éléments de prothèses fémorales modulaires adaptables à la morphologie de l'os à soutenir. La 10 présente invention s'applique au domaine des prothèses, et plus particulièrement au domaine des implants fémoraux. [1] The invention relates to a family of modular femoral prosthesis elements adaptable to the morphology of the bone to be supported. The present invention applies to the field of prostheses, and more particularly to the field of femoral implants.

ÉTAT DE LA TECHNIQUE STATE OF THE ART

[2] Il est connu dans l'état de la technique de réaliser une prothèse fémorale polyvalente en proposant une gamme de prothèses dont l'angle 15 cervico-diaphysaire varie linéairement en fonction de la longueur de la queue. On dit alors que la prothèse est à latéralisation homothétique. Toutefois, faire varier l'angle cervico-diaphysaire pour le conformer de manière satisfaisante à la taille de la prothèse engendre des contraintes de production évidentes. Par ailleurs, cette gamme ne fournit que des prothèses constituées d'une seule 20 pièce. Par conséquent, l'optimisation de prothèse doit être établi par un gabarit unique pour chaque patient afin d'être spécifiquement adaptée à sa morphologie. [2] It is known in the state of the art to provide a versatile femoral prosthesis by providing a range of prostheses whose cervico-diaphyseal angle varies linearly with the length of the tail. It is said that the prosthesis is homothetic lateralization. However, varying the cervico-diaphyseal angle to conform satisfactorily to the size of the prosthesis generates obvious production constraints. Moreover, this range only provides prostheses consisting of a single piece. Therefore, the prosthesis optimization must be established by a single template for each patient to be specifically adapted to its morphology.

[3] Il est également connu dans l'état de la technique d'adapter une prothèse fémorale à la morphologie d'un patient par l'assemblage deux pièces, 25 une queue et un élément en forme de col, aptes à former un angle cervicodiaphysaire variable. L'efficacité de tenue de la prothèse implique que les deux pièces, une fois assemblées, soient fixement solidaires l'une de l'autre et par conséquent, rend difficile un retrait éventuel de la prothèse. [3] It is also known in the state of the art to adapt a femoral prosthesis to the morphology of a patient by assembling two pieces, a tail and a neck-shaped element, capable of forming an angle cervicodiaphyseal variable. The holding efficiency of the prosthesis implies that the two parts, once assembled, are firmly fixed to each other and therefore makes it difficult to remove the prosthesis.

OBJET DE L'INVENTION OBJECT OF THE INVENTION

30 [004] La présente invention vise donc à remédier aux inconvénients de l'état de la technique en proposant une famille d'éléments de prothèses5 fémorales modulaires permettant l'assemblage d'un implant fémoral adaptable à chaque patient et le retrait aisé de l'implant. [004] The present invention therefore aims to overcome the drawbacks of the state of the art by proposing a family of modular femoral prosthesis elements 5 allowing the assembly of a femoral implant adaptable to each patient and the easy removal of the patient. 'implant.

[5] Pour ce faire, l'invention propose une famille d'éléments de prothèses fémorales modulaires comprenant une famille de fuseaux et une famille de cônes oblongs. Chaque fuseau de la famille comporte une partie inférieure définie par un premier axe longitudinal, sur laquelle sont formées des stries, s'étendant longitudinalement sur ses faces, et des rainures sur ses tranches. Chaque fuseau comporte également, une partie supérieure comportant des stries s'étendant transversalement sur ses faces, des dentures sur ses tranches et, un col modulaire sur lequel sont formées une cavité tronconique de section transversale oblongue, définie par un second axe longitudinal et destinée à la réception d'un cône oblong, ladite cavité tronconique étant prolongée par un dégagement taraudé de forme cylindrique, et une cavité hémisphérique centrée sur le premier axe longitudinal. Par ailleurs, chaque cône oblong de la famille comprend en outre une première portion d'extrémité de section transversale oblongue destinée à être insérée dans la cavité oblongue et une seconde portion d'extrémité tronconique de section transversale circulaire. [5] To do this, the invention provides a family of modular femoral prosthesis elements comprising a family of spindles and a family of oblong cones. Each spindle of the family has a lower portion defined by a first longitudinal axis, on which are formed ridges, extending longitudinally on its faces, and grooves on its edges. Each spindle also comprises an upper portion having striations extending transversely on its faces, teeth on its edges and a modular neck on which are formed a frustoconical cavity of oblong transverse cross section, defined by a second longitudinal axis and intended for receiving an oblong cone, said frustoconical cavity being extended by a threaded clearance of cylindrical shape, and a hemispherical cavity centered on the first longitudinal axis. Furthermore, each oblong cone of the family further comprises a first end portion of oblong cross section intended to be inserted into the oblong cavity and a second frustoconical end portion of circular cross section.

[6] Chacun des fuseaux et des cônes oblongs se différencie des autres fuseaux et des autres cônes constituant la famille par sa dimension 20 longitudinale. [6] Each of the spindles and oblong cones differs from other spindles and other cones constituting the family by its longitudinal dimension.

[7] De plus, chaque fuseau est apte à être associé alternativement à plusieurs cônes oblongs pour constituer une prothèse fémorale modulaire, dont l'angle cervico-diaphysaire formé entre les deux axes longitudinaux est constant. La cavité hémisphérique est disposée de manière à pouvoir y insérer 25 un outil d'impaction pour impacter la prothèse dans le premier axe longitudinal, le dégagement taraudé étant agencé de manière à pouvoir y insérer, après retrait du cône oblong, un outil fileté pour le retrait de la prothèse. La prothèse ainsi assemblée est impactée dans le fémur d'un patient par insertion d'un outil d'impaction dans la cavité hémisphérique et est retirée du fémur du patient 30 après retrait du cône oblong, par un effort de traction suite à l'insertion d'un outil fileté dans le dégagement taraudé. [7] In addition, each spindle is adapted to be associated alternately with several oblong cones to form a modular femoral prosthesis, the cervico-diaphyseal angle formed between the two longitudinal axes is constant. The hemispherical cavity is arranged to be able to insert an impaction tool for impacting the prosthesis in the first longitudinal axis, the threaded recess being arranged to be able to insert, after removal of the oblong cone, a threaded tool for the removal of the prosthesis. The prosthesis thus assembled is impacted in the femur of a patient by insertion of an impaction tool in the hemispherical cavity and is removed from the femur of the patient 30 after removal of the oblong cone, by a tensile force following the insertion. a threaded tool in the threaded clearance.

[8] Préférentiellement, la seconde portion d'extrémité tronconique de section transversale circulaire du cône oblong comprend un renfoncement pour la fixation d'un élément de type tête sphérique. Par ailleurs, le cône oblong 35 comporte un axe confondu avec le second axe longitudinal ce qui permet l'amélioration de la tenue du cône oblong dans le col modulaire une fois la prothèse implantée. [8] Preferably, the second frustoconical end portion of circular cross section of the oblong cone comprises a recess for fixing a spherical head type element. Furthermore, the oblong cone 35 has an axis coinciding with the second longitudinal axis which allows the improvement of the holding of the oblong cone in the modular neck once the implanted prosthesis.

[009] Avantageusement, afin de balayer la plus large plage de morphologie possible, la dimension longitudinale du fuseau est comprise entre 127mm et 167mm et la dimension longitudinale du cône oblong est comprise entre 45mm et 65mm. [009] Advantageously, in order to scan the widest range of possible morphology, the longitudinal dimension of the spindle is between 127mm and 167mm and the longitudinal dimension of the oblong cone is between 45mm and 65mm.

[0010] Selon un mode de réalisation avantageux, la prothèse formée par le fuseau et le cône oblong est recouverte d'un matériau microbillé. Ce matériau particulier comporte des charges sphériques renforçantes de très faible diamètre visant à la bonne tenue en compression et en cisaillement de la prothèse lorsque celle-ci est en mouvement dans le corps du patient. According to an advantageous embodiment, the prosthesis formed by the spindle and the oblong cone is covered with a microbead material. This particular material comprises spherical reinforcing fillers of very small diameter aimed at the good resistance in compression and shearing of the prosthesis when it is moving in the body of the patient.

For the sake of clarity, identical or similar elements of the various embodiments are marked with identical reference signs throughout the figures.

EXEMPLE DE RÉALISATION EXAMPLE OF REALIZATION

25 [0013] Sur la figure 1 est représentée une vue d'un fuseau 1 selon l'invention. Le fuseau 1 défini selon l'axe géométrique Al, présente sur sa partie inférieure 1 a des stries 3 s'étendant longitudinalement de manière à empêcher la rotation de la prothèse, une fois le fuseau 1 associé à un cône oblong. Leur nombre est limité afin de réaliser un compromis entre le mouvement de rotation et la minimisation des efforts pour le retrait de la prothèse. En parallèle, la partie inférieure 1 a comporte également des rainures 5 sur ses tranches qui permettent de diminuer le nombre de stries 3 tout en annihilant la rotation de la prothèse. [0014] La partie supérieure 1 b du fuseau présente quant à lui des stries 7 s'étendant transversalement sur sa largeur. Couplées à des dentures 4, ces stries 7 permettent le maintien de la prothèse implantée et limite les mouvements de varisation et de valgisation du fémur. FIG. 1 shows a view of a spindle 1 according to the invention. The spindle 1 defined along the geometric axis A1, has on its lower part 1a streaks 3 extending longitudinally so as to prevent the rotation of the prosthesis, once the spindle 1 associated with an oblong cone. Their number is limited in order to achieve a compromise between the rotational movement and the minimization of efforts for removal of the prosthesis. In parallel, the lower part 1a also has grooves 5 on its edges which make it possible to reduce the number of grooves 3 while annihilating the rotation of the prosthesis. The upper part 1b of the spindle has meanwhile streaks 7 extending transversely across its width. Coupled with teeth 4, these grooves 7 allow the maintenance of the implanted prosthesis and limits the movements of varisation and valgization of the femur.

[0015] Par ailleurs, la partie supérieure 1 b comporte un col modulaire 11, 10 dans lequel sont formés des cavités 8 et 10 dirigé selon I' axe géométrique A2. L'angle a formé entre les axes Al et A2 est fixé de manière standard à 135°. La cavité 8 est de section transversale oblongue, de forme tronconique et, est destinée à recevoir un cône oblong. Elle est prolongée par un dégagement taraudé 9 de plus petite section visant à recevoir un outil fileté. La fixation de 15 l'outil fileté dans le dégagement 9 permet alors de retirer pratiquement le fuseau par un effort de traction. De plus, ainsi définie, la cavité 8 recevant le cône oblong bouche le dégagement taraudé 9, interdisant par conséquent toute pollution du dégagement 9 susceptible d'affecter la facilité du retrait de la prothèse. Avantageusement, le col modulaire 11 présente une seconde cavité 20 10 de forme hémisphérique et dirigée selon l'axe géométrique Al, permettant l'impaction de la prothèse dans l'axe du fémur du patient. Selon la taille de la prothèse à implanter, la dimension longitudinale du fuseau mesurée entre son col modulaire 1l et son extrémité de queue 6 varie entre 127 et 167 millimètres. Furthermore, the upper part 1b has a modular neck 11, 10 in which are formed cavities 8 and 10 directed along I geometric axis A2. The angle formed between the axes A1 and A2 is set in a standard manner at 135 °. The cavity 8 is oblong in cross section, frustoconical in shape and is intended to receive an oblong cone. It is extended by a threaded clearance 9 of smaller section for receiving a threaded tool. Fixing the threaded tool in the clearance 9 then makes it possible to substantially remove the spindle by a traction force. In addition, thus defined, the cavity 8 receiving the oblong cone blocks the threaded clearance 9, thus preventing any pollution of the clearance 9 likely to affect the ease of removal of the prosthesis. Advantageously, the modular neck 11 has a second cavity 20 10 of hemispherical shape and directed along the geometric axis A1, allowing impaction of the prosthesis in the axis of the femur of the patient. Depending on the size of the prosthesis to be implanted, the longitudinal dimension of the spindle measured between its modular neck 11 and its tail end 6 varies between 127 and 167 millimeters.

[0016] La figure 2 représente une vue du col modulaire 11 selon l'invention. 25 La cavité 8 est une cavité oblongue tronconique définie selon l'axe A2. Sa forme oblongue permet l'encastrement d'un cône oblong mâle (non-illustré) dont la taille de sa section transversale définit une limite de profondeur d'encastrement. Plus précisément, quelque soit la taille de la section transversale de l'élément destiné à être inséré dans la cavité 8, la forme de la 30 cavité 8 permet une fixation solide de l'encastrement. Par ailleurs, cette cavité 8 est pourvue en son centre d'un dégagement 9 en forme de cylindre de révolution autour de l'axe A2. Le dégagement 9 est taraudé afin de pouvoir y insérer un outil fileté. Le col modulaire 11 présente également une cavité hémisphérique 10 dirigée selon l'axe géométrique Al permettant une impaction 35 de la prothèse dans l'axe du fémur du patient. [0017] Sur la figure 3a est illustrée une vue d'un cône oblong 15 selon l'invention. Le cône 15 comporte en outre une première portion 16 de section transversale oblongue et de forme tronconique. Sa section transversale 17 illustrée sur la figure 3b est conformée de telle sorte que le cône 15 soit adapté à la cavité 8 du col modulaire 11. Par ailleurs, la seconde portion du cône oblong 18 présente une section transversale circulaire pourvue d'un renfoncement 19. Par le biais de ce renfoncement 19, la seconde portion 18 est apte à être associée à un élément d'extrémité, par exemple, une tête sphérique. Les dimensions longitudinales des cônes oblongs formant la famille de cônes sont comprises entre 45 et 65 millimètres. Figure 2 shows a view of the modular neck 11 according to the invention. The cavity 8 is a frustoconical oblong cavity defined along the axis A2. Its oblong shape allows the embedding of an oblong male cone (not shown) whose size of its cross section defines a limit of embedment depth. More specifically, whatever the size of the cross section of the element intended to be inserted in the cavity 8, the shape of the cavity 8 allows a solid fixing of the recess. Moreover, this cavity 8 is provided at its center with a clearance 9 in the form of a cylinder of revolution about the axis A2. The clearance 9 is tapped in order to insert a threaded tool. The modular neck 11 also has a hemispherical cavity 10 directed along the geometric axis A1 allowing impaction 35 of the prosthesis in the axis of the femur of the patient. In Figure 3a is shown a view of an oblong cone 15 according to the invention. The cone 15 further comprises a first portion 16 of oblong cross section and of frustoconical shape. Its cross section 17 illustrated in Figure 3b is shaped such that the cone 15 is adapted to the cavity 8 of the modular neck 11. Furthermore, the second portion of the oblong cone 18 has a circular cross section provided with a recess 19 Through this recess 19, the second portion 18 is adapted to be associated with an end element, for example, a spherical head. The longitudinal dimensions of the oblong cones forming the family of cones are between 45 and 65 millimeters.

[0018] L'invention n'est pas limitée aux aspects et aux modes de réalisations précédemment décrits. En effet, il est tout à fait envisageable de constituer une famille de prothèses fémorales modulaires plus étoffée, proposant davantage de fuseaux et de cônes oblongs. Par ailleurs, il est également possible d'ajouter un paramètre variable supplémentaire, tel que l'angle cervico-daphysaire, ce qui permettrait d'élargir et de compléter la famille d'éléments de prothèses fémorales modulaires, ou bien encore, d'adapter l'invention à d'autres types d'implants. The invention is not limited to the aspects and embodiments described above. Indeed, it is quite possible to build a family of modular femoral prosthesis more expanded, offering more spindles and oblong cones. Moreover, it is also possible to add an additional variable parameter, such as the cervico-daphyseal angle, which would allow to widen and complete the family of elements of modular femoral prostheses, or even to adapt the invention to other types of implants.
