Abstract

The prosthesis consists of a metatarsal component (2) with a bone anchoring shank (5) and an articulated joint surface (6), and a phalangeal component (3) made up of a section (10) with an anchoring shank (12) and an intermediate section (11) with a joint surface (22). The intermediate section allows the phalangeal component to rotate relative to the metatarsal component about its lengthwise axis. The anchoring shanks have self-tapping threads (7) for fixing without cement, and the two joint surfaces (6, 22) are semi-cylindrical in shape.

Description

La présente invention concerne une prothèse métatarso- phalangienne. The present invention relates to a metatarsophalangeal prosthesis.

Les prothèses métatarso-phalangiennes existantes avèrent ne pas respecter parfaitement l'articulation métatarso-phalangienne anatomique. II en résulte un fonctionnement défectueux de prothèses et une usure prématurée de celle-ci, ainsi que le risque de diverses complications. Existing metatarsophalangeal prostheses have failed to fully respect the anatomical metatarsophalangeal joint. This results in defective operation of prostheses and premature wear thereof, as well as the risk of various complications.

La présente invention vise à remédier à cet inconvénient essentiel. The present invention aims to remedy this essential disadvantage.

La prothèse qu'elle concerne comprend - un composant métatarsien possédant une partie allongée, qui permet l'ancrage de ce composant à un os métatarsien, et une partie d'articulation, qui s'étend perpendiculairement à l'axe longitudinal de cette partie allongée ; et - un composant phalangien possédant une partie allongée, qui permet l'ancrage de ce composant à un os phalangien, et une partie d'articulation, qui s'étend perpendiculairement à l'axe longitudinal de cette partie allongée, les parties d'articulation étant conformées pour coopérer l'une avec l'autre. The prosthesis it concerns comprises - a metatarsal component having an elongate portion, which allows the anchoring of this component to a metatarsal bone, and a hinge portion, which extends perpendicularly to the longitudinal axis of this elongated portion ; and - a phalangeal component having an elongate portion, which allows anchoring of this component to a phalangeal bone, and a hinge portion, which extends perpendicularly to the longitudinal axis of this elongated portion, the hinge portions being shaped to cooperate with each other.

Selon l'invention, la prothèse est conformée de telle sorte qu'elle autorise le pivotement du composant phalangien rapport au composant métatarsien autour d'un axe longitudinal. According to the invention, the prosthesis is shaped such that it allows the pivoting of the phalangeal component relative to the metatarsal component around a longitudinal axis.

pivotement permet à la prothèse de respecter seulement l'articulation métatarso-phalangienne mais également l'articulation métatarso-sésamoïdienne. En effet, l'articulation métatarso phalangienne est constituée par deux articulations : l'articulation métatarso- sésamoïdienne, qui est verrouillée lors de la position dite "du toe-off", permettant force de propulsion maximale lors du passage du pas et de la course, et l'articulation métatarso-phalangienne proprement dite, qui permet, de 0 à 80 , au premier orteil de s'adapter à tous les terrains par les possibilités de rotation multidirectionnelle qu'elle offre. pivoting allows the prosthesis to respect only the metatarsophalangeal joint but also the metatarsal-sesamoid joint. In fact, the metatarsal phalangeal joint is composed of two articulations: the metatarsosesamoid joint, which is locked during the so-called "toe-off" position, allowing maximum propulsive force during the passage of the step and the stroke , and the metatarsophalangeal joint proper, which allows, from 0 to 80, the first toe to adapt to all terrains by the possibilities of multidirectional rotation it offers.

La prothèse selon l'invention, grâce audit pivotement, permet une rotation automatique de la phalange par rapport à la tête métatarsienne, sans intervention des éléments musculaires, ligamentaires ou tendineux, ce qui assure le respect précité tant de l'articulation métatarso-sesamoïdienne que de l'articulation métatarso-phalangienne proprement dite. The prosthesis according to the invention, by virtue of said pivoting, allows an automatic rotation of the phalanx with respect to the metatarsal head, without intervention of the muscular, ligamentous or tendonous elements, which ensures the aforementioned respect for both the metatarsopelamoidal joint and of the metatarsophalangeal joint proper.

La forme hémi-cylindrique des parties d'articulation augmente le bras de levier et améliore les possibilités de rotation d'un composant par rapport à l'autre. Cette forme permet à la néo-articulation d'être au maximum de son efficacité, surtout en flexion dorsale, quelle soit la position de la phalange. The hemi-cylindrical shape of the hinge portions increases the lever arm and improves the rotational capability of one component relative to the other. This form allows the neo-articulation to be at its maximum efficiency, especially in dorsal flexion, whatever the position of the phalanx.

Avantageusement, dans ce cas, le composant en deux éléments est le composant phalangien, ce qui permet d'améliorer les possibilités de rotation de ce composant phalangien. Advantageously, in this case, the two-component component is the phalangeal component, which makes it possible to improve the possibilities of rotation of this phalangeal component.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, deux formes de réalisation possibles de la prothèse métatarso-phalangienne qu'elle concerne. For a good understanding, the invention is again described below with reference to the attached schematic drawing showing, by way of non-limiting example, two possible embodiments of the metatarsophalangeal prosthesis it relates.

La figure 1 en est une vue de côté, selon une première forme réalisation, en coupe longitudinale ; la figure 2 en est une vue de côté, selon une deuxième forme réalisation, en coupe longitudinale ; figure 3 est une vue d'un élément et d'un composant qu'elle comprend, perpendiculairement à la vue selon la figure 2, et figure 4 est une vue latérale de la prothèse, après mise en place entre un os métatarsien et un os phalangien. Figure 1 is a side view, in a first embodiment, in longitudinal section; Figure 2 is a side view, according to a second embodiment, in longitudinal section; FIG. 3 is a view of an element and a component that it comprises, perpendicular to the view according to FIG. 2; and FIG. 4 is a side view of the prosthesis, after placement between a metatarsal bone and a bone. phalangeal.

La figure 1 représente une prothèse métatarso-phalangienne comprenant un composant métatarsien 2 et un composant phalangien 3. composant métatarsien 2 possède une partie allongée 5, qui permet son ancrage à un os métatarsien, et une partie d'articulation 6, qui s'étend perpendiculairement à l'axe longitudinal de la partie 5. FIG. 1 represents a metatarsophalangeal prosthesis comprising a metatarsal component 2 and a phalangeal component 3. The metatarsal component 2 has an elongate portion 5, which allows it to be anchored to a metatarsal bone, and a hinge portion 6, which extends perpendicular to the longitudinal axis of Part 5.

Cette dernière présente une forme tronconique et comprend un filet auto-taraudeur 7 sur sa face extérieure. La face extérieure de cette partie 5, ainsi que ce filet 7, sont revêtus d'un matériau ostéo-conducteur, notamment l'hydroxyapatite de calcium. The latter has a frustoconical shape and comprises a self-tapping thread 7 on its outer face. The outer face of this portion 5, and this thread 7, are coated with an osteoconductive material, in particular calcium hydroxyapatite.

partie 6 présente un bossage 8 convexe, en forme de calotte sphérique. part 6 has a convex boss 8, shaped spherical cap.

composant phalangien 3 est formé par deux éléments, savoir une embase 10 et un élément intermédiaire 11. Phalangeal component 3 is formed by two elements, namely a base 10 and an intermediate element 11.

L'embase 10 présente une partie d'ancrage 12 similaire à partie 5 et une partie d'extrémité 13. Cette partie d'ancrage 12 comprend un puits central 15 de forme cylindrique. The base 10 has an anchoring portion 12 similar to part 5 and an end portion 13. This anchoring portion 12 comprises a central well 15 of cylindrical shape.

partie d'extrémité 13 s'étend dans un plan perpendiculaire à la direction longitudinale de la partie 12 et présente une paroi périphérique circulaire 1 qui délimite un logement 17. end portion 13 extends in a plane perpendicular to the longitudinal direction of the portion 12 and has a circular peripheral wall 1 which delimits a housing 17.

figures 2 et 3 montrent une prothèse très similaire à celle qui vient d'etre décrite, sinon que la partie 6 présente un bossage 8 de forme hémi-cylindrique tandis que la partie 21 présente un évidemment 22 de forme hemi-cylindrique correspondant à celle du bossage 8. L'axe du pion 20 passe par l'axe générant l'évidemment 22. Par simplification, les mêmes numéros de référence que précédemment ont été utilisés. Figures 2 and 3 show a prosthesis very similar to that just described, except that the portion 6 has a boss 8 of hemi-cylindrical shape while the portion 21 has a hemi-cylindrical shape 22 corresponding to that of the boss 8. The axis of the pin 20 passes through the axis generating the obvious 22. For simplicity, the same reference numbers as before were used.

prothèse 1 selon l'une ou l'autre de ces formes de realisation est conformée de telle sorte qu'elle autorise le pivotement du composant phalangien par rapport au composant métatarsien 2 autour axe longitudinal. Cette prothèse 1 respecte ainsi l'articulation du métatarse 50 par rapport au sésamoïde 51 (figure 4), en permettant une rotation automatique de la phalange 52 par rapport à la tête métatarsienne sans intervention éléments musculaires, ligamentaires ou tendineux. Prosthesis 1 according to either of these embodiments is shaped such that it allows pivoting of the phalangeal component relative to the metatarsal component 2 about longitudinal axis. This prosthesis 1 thus respects the articulation of the metatarsal 50 with respect to the sesamoid 51 (FIG. 4), allowing an automatic rotation of the phalanx 52 with respect to the metatarsal head without the intervention of muscle, ligament or tendon elements.

L'articulation prothétique est ainsi au maximum de son efficacité, surtout en flexion dorsale, quelle que soit la position de la phalange 52.The prosthetic joint is thus at its maximum efficiency, especially in dorsal flexion, whatever the position of the phalanx 52.
