Abstract

The element is characterised in that the stem 1a has, in combination, vertical grooves 1c1 and an ovoid cross-section of large frontal axis.

Description

Elément fémoral d'une endoprothèse de hanche. Femoral component of a hip endoprosthesis.

Plus particulièrement, l'invention concerne une tige fémorale multibloquée pour prothèse totale de la hanche. More particularly, the invention relates to a multiblocked femoral stem for total hip prosthesis.

On rappelle que le but de l'arthroplastie totale est de réaliser une articulation stable, mobile et indolore, en mettant en place un implant de longévité suffisante et apte a être changé si nécesaire. Il existe, a ce jour, une très grande variété de prothèses totales de hanche. It is recalled that the goal of total arthroplasty is to achieve a stable joint, mobile and painless, by implementing an implant of sufficient longevity and able to be changed if necessary. There is, to date, a very wide variety of total hip prostheses.

On sait par ailleurs que, pour avoir un bon maintien de 1'élément de prothèse, avec ou sans ciment, le remplissage niétaphyso-diaphysaire est très imprortant.  It is also known that, in order to have a good support of the prosthesis element, with or without cement, the nietaphyso-diaphyseal filling is very unpredictable.

De face, dans un plan frontal, le blocage sur les corticales est nécesaire a la transmission des contraintes physiologiques en compression, du fait du moment fléchissant. From the front, in a frontal plane, the blocking on the cortices is necessary for the transmission of the physiological constraints in compression, because of the bending moment.

De profil, dans un plan sagittal, une prothèse étroite risque, en s'enfonçant, de transformer le moule de ciment en deux hémivalves, aux mauvaises propriétés micaniques.  In profile, in a sagittal plane, a narrow prosthesis risks, by sinking, to transform the cement mold into two hemivalves, with poor properties micaniques.

De plus, une prothèse étroite ne permet pas de lutter contre les contraintes en torsion ; elle est située trop en avant, et a tendance a se retroverser.  In addition, a narrow prosthesis does not allow to fight against torsional stresses; it is situated too far forward, and has a tendency to retrovert itself.

Le site prothétique doit donc être comblé au maximum par la prothèse. The prosthetic site must therefore be filled to the maximum by the prosthesis.

Un des problèmes que se propose de résoudre l'invention, est de réaliser une prothèse susceptible d'être implantée avec ou sans ciment, en étant apte a remplir d'une manière satisfaisante le site prothétique, notamment au niveau de la niétaphyse.  One of the problems to be solved by the invention is to provide a prosthesis that can be implanted with or without cement, being able to satisfactorily fill the prosthetic site, particularly at the level of the niethaphysis.

Pour résoudre ce probleme, il a été réalisé des implants dits personnalisés, en utilisant une conception et fabrication assitées par ordinateur. Une telle méthode nécessite une infrastructure adaptée et présente certains inconvénients :
- cathode de mesure du site prothétique aléatoire par la radiographie conventionnelle : rigueur de la méthode qui la rend difficile å appliquer ; impossibilité de passer d'un intervenant humain au stade de l'interprétation des données radiologiques et de leur transmission å la machine
- méthode de mesure du site prothétique par la toniodensitoniétrie trop onéreuse
- délai entre la mesure et l'obtention de la prothèse assez long, ce qui rend impossible l'utilisation systématique de ce type de prothèse.To solve this problem, so-called customized implants were made using computer-assisted design and manufacturing. Such a method requires a suitable infrastructure and has certain disadvantages:
- measuring cathode of the random prosthetic site by conventional radiography: rigor of the method which makes it difficult to apply; impossibility of switching from a human worker to the interpretation of radiological data and their transmission to the machine
- method of measurement of the prosthetic site by the too expensive toniodensitoniétrie
- Delay between the measurement and obtaining the prosthesis long enough, which makes it impossible to use this type of prosthesis systematically.

L'invention s'est fixée pour but de remédier å ces inconvénients, d'une manière simple et efficace en ayant pour objectif d'obtenir un remplissage métaphyso-diaphysaire maximum.  The object of the invention is to remedy these disadvantages in a simple and effective way with the objective of obtaining a maximum metaphyseal-diaphysis filling.

L'élément prothétique fémoral est notamment du type de ceux comprenant une tige et un col réunis par une platine. The femoral prosthetic element is particularly of the type comprising a stem and a neck joined by a platinum.

Le problème pose est résolu par un profil particulier et adapté de la tige fémorale qui est remarquable en ce que la tige présente en combinaison des cannelures verticales et une section transversale de forme ovoïde a grand axe frontal. The problem posed is solved by a particular and adapted profile of the femoral stem which is remarkable in that the rod has in combination vertical splines and a cross-section of ovoid shape with a large front axis.

Avantageusement, les cannelures sont formées sur chacune des faces antérieure et postérieure de la tige, depuis la partie connue sous le nom de platine Jusqu'à l'extrémité inférieure de ladite tige, lesdites cannelures étant unidirectionnelles et parallèles. Advantageously, the grooves are formed on each of the front and rear faces of the rod, from the portion known as platinum to the lower end of said rod, said grooves being unidirectional and parallel.

Le chant rectiligne des cannelures est plat. The straight edge of the flutes is flat.

Chaque cannelure est séparée par une rainure de section très sensiblement méplate. Each groove is separated by a groove of very substantially flat section.

Le bord latéral interne de la tige comprend, à partir de son extrémité inférieure, un segment sensiblement rectiligne et vertical prolongé par un rayon de courbure concave dirigé vers l'extérieur et qui s'infléchit pour se raccorder avec le col par une partie concave de faible rayon de courbure dirigée vers l'intérieur, tandis que le bord latéral externe dudit corps comprend, à partir de l'extrémité inférieure de la tige, un segment sensiblement rectiligne et vertical prolongé par un segment légèrement oblique en direction de l'intérieur ledit segment étant raccordé au col par une partie droite disposée très sensiblement dans un plan horizontal. The inner lateral edge of the stem comprises, from its lower end, a substantially rectilinear and vertical segment extended by a concave radius of curvature directed outwards and which flexes to connect with the neck by a concave portion of a small inwardly directed radius of curvature, while the outer lateral edge of said body comprises, from the lower end of the stem, a substantially straight and vertical segment extended by a segment slightly oblique towards the interior of said segment being connected to the neck by a straight portion disposed very substantially in a horizontal plane.

L'extrémité inférieure de la tige est tronconique et arrondie. The lower end of the stem is frustoconical and rounded.

La partie connue sous le nom de platine est de section méplate en étant formée en retrait de la partie supérieure du corps de la tige et du col. The portion known as platinum is of flat section being formed recessed from the upper body of the shaft and neck.

Les faces antérieure et postérieure de la tige sont parallèles et sont évasées de bas en haut sur très sensiblement les 2/5 supérieurs du corps de la tige. The anterior and posterior faces of the stem are parallel and are flared from bottom to top on very substantially the upper 2/5 of the body of the stem.

A partir de cette conception de base de l'lément prothétique, le choix du matériau s'avère important. Notamment, le matériau doit être biocompétent et biocompatible. From this basic design of the prosthetic element, the choice of material is important. In particular, the material must be biocompetent and biocompatible.

On rappelle que la biocompétence est l'aptitude du matériau a remplir sa fonction. La biocompatibilité est l'ensemble des phénomènes mis en jeu dans un environnement physiologique, de telle sorte que le matériau ne soit pas dangereux pour l'organisme, et que l'organisme ne dégrade pas le matériau. Le tissu biologique est un milieu corrosif, qui risque d'entraîner une dégradation chimique ou électro- chimique. La tolérance de l'organisme, au niveau local comme systémique, doit être bonne vis-à-vis du matériau, comme de ses produits d'usure ou de corrosion. It is recalled that biocompetence is the ability of the material to fulfill its function. Biocompatibility is the set of phenomena involved in a physiological environment, so that the material is not harmful to the body, and the body does not degrade the material. Biological tissue is a corrosive medium that may cause chemical or electrochemical degradation. The tolerance of the organism, at the local as well as the systemic level, must be good with respect to the material, as well as its products of wear or corrosion.

Pour résoudre ce problème, l'élément prothétique de hanche, notamment l'ensemble de la tige, est réalisé dans un alliage à forger, i base de titane, contenant 5,5 a 6,5 % d'aluminium et 3,5 a 4,5 X de vanadium, ledit alliage étant connu sous le nom de TAcV. To solve this problem, the hip prosthetic element, in particular the entire stem, is made of a forging alloy, based on titanium, containing 5.5 to 6.5% aluminum and 3.5 to 4.5 X vanadium, said alloy being known as TAcV.

L'invention est exposée ci-après plus en détail a l'aide des dessins annexés dans lesquels
La figure 1 est une vue de face de la tige fémorale.The invention is explained below in more detail with the aid of the accompanying drawings in which
Figure 1 is a front view of the femoral stem.

La figure 2 est une vue de profil correspondant a la figure 1. Figure 2 is a side view corresponding to Figure 1.

Les figures 3, 4 et 5 sont des vues en coupe transversale considérées respectivement selon les lignes 3-3, 4-4 et 5-5 de la figure 1. Figures 3, 4 and 5 are cross-sectional views taken respectively along the lines 3-3, 4-4 and 5-5 of Figure 1.

La figure 6 est une vue en coupe transversale du fémur montrant la mise en place de l'élément prothétique sans ciment. Figure 6 is a cross-sectional view of the femur showing the placement of the cementless prosthetic element.

la figure 7 est une vue semblable & la figure 6, dans le cas oû l'élément prothétique est implanté avec du ciment. Figure 7 is a view similar to Figure 6, in the case where the prosthetic element is implanted with cement.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation des figures des dessins. In order to make more concrete the object of the invention, it is now described in a non-limiting manner with reference to the embodiments of the figures of the drawings.

On rappelle que l'élément fémoral désigné dans son ensemble par Cl) comprend une tige < la), un col (lob) raccordé å la tige par une platine < lc > , ledit col étant apte à recevoir, directement ou d'une manière rapportée, une pièce complémentaire du type cupule. It is recalled that the femoral element generally designated by Cl) comprises a stem (la), a neck (lob) connected to the stem by a plate (lc), said neck being able to receive, directly or in a manner reported, a complementary piece of the cupule type.

Selon l'invention, la tige plan présente en combinaison des cannelures verticales (las) et une section transversale de forme ovoïde à grand axe frontal. Les cannelures < laI) sont formées sur chacune des faces antérieure et postérieure, depuis la partie connue sous le nom de platine < lc > jusqu'à l'extrémité inférieure de la tige. According to the invention, the planar rod has in combination vertical grooves (las) and a cross section of ovoid shape with a large front axis. The flutes (la) are formed on each of the anterior and posterior faces, from the part known as platinum <1c> to the lower end of the stem.

Les cannelures sont unidirectionnelles et parallèles entre elles et à l'axe vertical de la tige. The flutes are unidirectional and parallel to each other and to the vertical axis of the rod.

Comme le montre les vues en coupe des figures 3, 4 et 5, le chant rectiligne des cannelures (lai) est plat, tandis que les intervalles de séparation entre chacune desdites cannelures, constituent des rainures de section sensiblement méplate. As shown in sectional views of Figures 3, 4 and 5, the straight edge of the grooves (lai) is flat, while the separation intervals between each of said grooves, are grooves of substantially flat section.

Le bord latéral interne du corps de la tige (la) comprend, a partir de son extrémité inférieure, un segment sensiblement rectiligne et vertical (a) prolongé par un rayon de courbure concave (b) dirigé vers l'extérieur. Ce rayon (b) s'infléchit pour être raccordé au col < lb) par une partie concave < c) de faible rayon de courbure. The inner side edge of the shaft body (1a) comprises, from its lower end, a substantially straight and vertical segment (a) extended by a concave radius of curvature (b) directed outwards. This radius (b) flexes to be connected to the neck (1b) by a concave portion (c) of small radius of curvature.

Le bord latéral externe de la tige < la) comprend a partir de son extrémité inférieure, un segment sensiblement rectiligne et vertical (d) prolongé par un segent légèrement oblique < e) en direction de l'intérieur selon un angle (or) par rapport A l'axe vertical. Ce segment oblique (e) est raccordé au col tlb) par une partie droite (f) disposée très -sensiblement dans un plan horizontal å go par rapport a l'axe vertical de la tige < la). Cette partie droite (f) constitue la face supérieure de la tige. The outer lateral edge of the stem (la) comprises from its lower end a substantially rectilinear and vertical segment (d) extended by a slightly oblique segment (e) towards the interior at an angle (or) relative to At the vertical axis. This oblique segment (e) is connected to the neck tlb) by a straight part (f) arranged very -sensibly in a horizontal plane å go with respect to the vertical axis of the rod <la). This right part (f) constitutes the upper face of the rod.

L'extrémité inférieure (la2) de la tige - < la) est tronconique et arrondie. The lower end (la2) of the rod - <la) is frustoconical and rounded.

Les faces antérieures et postérieures de la tige sont parallèles et sont évasées de bas en haut sur très sensiblement les 2/5 supérieurs de la tige. Le col (lb) a une section cylindrique en étant incline selon un angle cervicodiaphysaire de l'ordre de 135'. Dans l'exemple illustré, l'extrémité supérieure du col est taillée en tronc de cone en étant apte a recevoir la tête ou cupule. The anterior and posterior faces of the stem are parallel and are flared from bottom to top on very substantially the upper 2/5 of the stem. The neck (Ib) has a cylindrical section being inclined at a cervicodiaphyseal angle of the order of 135 '. In the example shown, the upper end of the neck is cut into a cone trunk being able to receive the head or cup.

A noter que la platine < lc) est de section méplate en étant formée en retrait de la partie supérieure du corps de la tige < la) et du col (1b). Note that the plate (lc) is of flat section being formed recessed from the upper part of the body of the rod (la) and the neck (1b).

La face supérieure Cf) de la tige est percée d'un trou d'impaction < 2) situé dans le même alignement que l'axe vertical de ladite tige. La face inférieure du col (lb) est percée d'un trou d'extraction situé dans un plan perpendiculaire à celui de l'axe principal dudit col. The upper face Cf) of the rod is pierced with an impaction hole <2) located in the same alignment as the vertical axis of said rod. The lower face of the neck (lb) is pierced with an extraction hole located in a plane perpendicular to that of the main axis of said neck.

Le profil en section de la tige < la) en combinaison avec la conception et l'orientation des cannelures, s'avère très avantageux pour l'implantation et le maintien de la tige fé:norale dans le canal médulaire. Dans le cas où la prothèse est posée sans ciment figure 6), l'os spongieux se tasse entre les cannelures. Il apparaît macroscopiquement, un contact parfait et régulier de l'ensemble de la tige avec l'os. Ces résultats avantageux sont également vérifiés dans le cas où la prothèse est implantée avec du ciment (figure 7). The sectional profile of the rod (la) in combination with the design and orientation of the grooves, proves to be very advantageous for the implantation and maintenance of the femoral stem in the medial canal. In the case where the prosthesis is laid without cement figure 6), the cancellous bone is sandwiched between the grooves. It appears macroscopically, a perfect and regular contact of the whole stem with the bone. These advantageous results are also verified in the case where the prosthesis is implanted with cement (FIG. 7).

D'une manière avantageuse, l'élément fémoral < 1) est exécuté dans un alliage à forger à base de titane et contenant 5,5 å 6,5 % d'aluminium et 3,5 a 4,5 'S de vanadium.  Advantageously, the femoral component <1) is performed in a titanium-based forging alloy containing 5.5 to 6.5% aluminum and 3.5 to 4.5% vanadium.

Un tel alliage est connu sous la référence TACT. Such an alloy is known as TACT.

Les avantages ressortent bien de la description, en particulier on souligne, d'une manière particulièrement importante, que l'originalité de cette prothèse réside dans le fait qu'elle doit être implantée sans aucune résection osseuse et que les rainures et cannelures de cette prothèse sont destinées à s'implanter dans un fût fémoral où le spongieux a été repoussé et compressé par cette prothèse sans avoir été enlevé.  The advantages are apparent from the description, in particular it is emphasized, in a particularly important way, that the originality of this prosthesis lies in the fact that it must be implanted without any bone resection and the grooves and grooves of this prosthesis are intended to implant in a femoral shaft where the spongy has been repelled and compressed by this prosthesis without having been removed.
