The prosthesis includes an anti-dislocation portion consisting of a medial groove (111) formed in the wear shield of the metatarsal component. This cooperates with a medial projection (211) of exactly-corresponding cross-sectional configuration formed in the phalangeal component. ADVANTAGE - Combines increased freedom of joint movement with protection against dislocation.

Description

"PROTHESE TOTALE METATARSO-PHALANGIENNE DE SURFACAGE"
La présente invention concerne une prothèse totale métatarso-phalangienne de resurfaçage,
L'invention trouve une application particulièrement avantageuse dans le domaine des prothèses de resurfaçage des os concernant l'articulation mêtatarso-phalangienne. "TOTAL METATARSO-PHALANGIAN SURFACING PROSTHESIS"
The present invention relates to a total metatarsophalangeal resurfacing prosthesis,
The invention finds a particularly advantageous application in the field of bone resurfacing prostheses relating to the metatarsophalangeal joint.

Dans le domaine de l'orthopédie, il existe des prothèses totales métatarso-phalangiennes, dites de resurfaçage, au sens où elles respectent l'anatomie et la cinématique de l'articulation. Ces prothèses de type connu sont constituées de deux parties, à savoir un composant métatarsien et un composant phalangien. Le composant métatarsien comporte généralement un bouclier de frottement qui, pour être fixé de façon stable à l'extrémité distale du métatarse, doit avoir la forme la plus enveloppante possible, ce qui nécessite des résections rel#tivement importantes, en particulier celle des os sésamoldes. Or la destruction de ces os, qui participent à la sensation tactile de la marche, a pour inconvénient de pLcvoquer chez les patients des facteurs d'instabilité et de mauvaise appréhension du terrain. In the field of orthopedics, there are total metatarsophalangeal prostheses, called resurfacing, in the sense that they respect the anatomy and kinematics of the joint. These prostheses of known type consist of two parts, namely a metatarsal component and a phalangeal component. The metatarsal component generally comprises a friction shield which, in order to be fixed in a stable manner to the distal end of the metatarsus, must have the most enveloping shape possible, which requires relatively significant resections, in particular that of the sesamold bones . However, the destruction of these bones, which participate in the tactile sensation of walking, has the disadvantage of invoking in patients factors of instability and poor understanding of the terrain.

Ces mêmes prothèses, mettant à profit la bonne stabilité des composants, utilisent souvent des liaisons à charnière dont la rigidité permet d'éviter la luxation de l'articulation métatarso-phalangienne, avec cependant le risque de rupture dans le cas de chocs importants comme celui qui se produit lorsque le pied vient buter contre un obstacle telle qu'une marche d'escalier. These same prostheses, taking advantage of the good stability of the components, often use hinged connections whose rigidity makes it possible to avoid dislocation of the metatarsophalangeal joint, with however the risk of rupture in the case of significant shocks like that which occurs when the foot abuts an obstacle such as a stair step.

Aussi, le problème technique à résoudre par l'objet de la présente invention est de proposer une prothèse totale métatarso-phalangienne de resurfaçage, comprenant un composant métatarsien et un composant phalangien, prothèse qui permettrait de sauvegarder les os sésamoïdes tout en évitant une luxation du composant métatarsien rendue pls probable du fait de sa moindre rétention. Also, the technical problem to be solved by the object of the present invention is to propose a total metatarsophalangeal resurfacing prosthesis, comprising a metatarsal component and a phalangeal component, a prosthesis which would make it possible to save the sesamoid bones while avoiding dislocation of the metatarsal component made more likely due to its lower retention.

La solution au problème technique posé consiste, selon la présente invention, en ce que ledit composant métatarsien comporte un bouclier de frottement ayant sensiblement la forme d'une portion de sphère ouverte latéralement, et destiné à être fixé à l'extrémité distale du métatarse sans résection des os sésamoïdes, et en ce que ladite prothèse comporte un dispositif anti-luxation constitué par une rainure médiane aménagée sur le bouclier de frottement du composant métatarsien, et coopérant avec un promontoire médian, congruent à ladite rainure, aménagé sur le composant phalangien. The solution to the technical problem posed consists, according to the present invention, in that said metatarsal component comprises a friction shield having substantially the shape of a portion of sphere open laterally, and intended to be fixed to the distal end of the metatarsus without resection of the sesamoid bones, and in that said prosthesis comprises an anti-dislocation device constituted by a median groove arranged on the friction shield of the metatarsal component, and cooperating with a median promontory, congruent with said groove, arranged on the phalangeal component.

Ainsi, par une forme partiellement enveloppante du bouclier du composant métatarsien, la prothèse, objet de l'invention, permet d'éviter la résection des os sésamoïdes avec tous les avantages qu'il peut en résulter pour le confort de marche des patients. La diminution de rétention du composant métatarsien est compensée par le dispositif anti-luxa,::ion qui absorbe les contraintes induites lors de chocs, grâce à la coopération entre la rainure et le promontoire qui agissent comme une articulation souple, susceptible de se luxer élastiquement et partiellement, préservant ainsi le composant métatarsien de toute contrainte excessive dommageable pour sa stabilité
La description qui va suivre, en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.Thus, by a partially enveloping shape of the shield of the metatarsal component, the prosthesis, object of the invention, makes it possible to avoid resection of the sesamoid bones with all the advantages that it may result for the walking comfort of the patients. The reduction in retention of the metatarsal component is compensated by the anti-luxa, :: ion device which absorbs the stresses induced during impacts, thanks to the cooperation between the groove and the headland which act as a flexible joint, capable of luxating elastically. and partially, thus preserving the metatarsal component from any excessive stress damaging for its stability
The description which follows, with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.

FIGS. 2a, 2b and 2c are respectively a left view, a half front view and a half top view of the metatarsal component mounted in FIG. 1.

Les figures 3a, 3b, et 3c sont respectivement une vue de gauche, une vue de face en coupe selon la ligne
A-A de la figure 3a, et une vue de dessus en coupe selon la ligne B-B de la figure 3b.Figures 3a, 3b, and 3c are respectively a left view, a front view in section along the line

La figure 1 montre en vue de côté une prothèse totale métatarso-phalangienne de resurfaçage, comprenant un composant métatarsien 100 et un composant phalangien 200. FIG. 1 shows a side view of a total metatarsophalangeal resurfacing prosthesis, comprising a metatarsal component 100 and a phalangeal component 200.

Comme on peut le voir sur les figures 1 et 2a, ledit composant métatarsien 100 comporte un bouclier 110 de frottement ayant sensiblement la forme d'une portion de sphère ouverte latéralement, et destiné à ëtre fixé à l'extrémité distale du mététatarse 10 sans résection des os sésamoïdes 11. Dans le mode de réalisation montré aux figures 1 et 2 , le bouclier 110 de frottement a une forme relativement peu enveloppante, inscrite dans une demI-sphère.  As can be seen in Figures 1 and 2a, said metatarsal component 100 comprises a friction shield 110 having substantially the shape of a portion of sphere open laterally, and intended to be fixed to the distal end of the metetatarse 10 without resection sesamoid bones 11. In the embodiment shown in FIGS. 1 and 2, the friction shield 110 has a relatively non-enveloping shape, inscribed in a hemisphere.

La mise en place du composant métatarsien 100 sur le métatarse 10 exige, par exemple, trois resectrons planes de l'extrémité distale de l'os sur lesquels viennenent er appui trois faces planes conjuguées 113,114,115 , usinées sur la partie interne du bouclier 110. The establishment of the metatarsal component 100 on the metatarsus 10 requires, for example, three planar resectrons from the distal end of the bone on which come to bear three planar conjugate faces 113,114,115, machined on the internal part of the shield 110.

Bien entendu, la stabilité dudit bouclier de frottement, tel qu'il est représenté sur les figures 1,2a à 2c, est inférieure à celle d'un bouclier plus enveloppant qui nécessiterait la résection des os sésamoïdes 11. Aussi, de façon à compenser cette moindre rétention, l'invention prévoit de réduire les contraintes appliquées au composant métatarsien 100 à l'aide d'un dispositif anti-luxation constitué par une rainure médiane 111, visible sur les figures 1, 2a et 2c, aménagée sur le bouclier 110 de frottement du composant métatarsien, et par un promontoire médian 211, montrée aux figures 1, 3b et 3c, aménagé sur le corps 210 du composant phalangien 200. Le promontoire 211 et la rainure 111 sont congruents l'un à l'autre de manière à assurer leur coopération lorsque l'articulation métatarso-phalangienne ainsi constituée est sollicitée. Of course, the stability of said friction shield, as shown in FIGS. 1,2a to 2c, is less than that of a more enveloping shield which would require resection of the sesamoid bones 11. Also, so as to compensate this lower retention, the invention provides for reducing the stresses applied to the metatarsal component 100 using an anti-dislocation device constituted by a central groove 111, visible in FIGS. 1, 2a and 2c, arranged on the shield 110 friction of the metatarsal component, and by a median promontory 211, shown in Figures 1, 3b and 3c, arranged on the body 210 of the phalangeal component 200. The promontory 211 and the groove 111 are congruent to each other so to ensure their cooperation when the metatarsophalangeal joint thus formed is requested.

Les figures 2c et 3c indiquent que la rainure 111 et le promontoire 211 peuvent présenter en section droite un profil composé d'une portion de cercle comprise entre deux épaulements rectilignes, respectivement référencés 112 et 212. FIGS. 2c and 3c indicate that the groove 111 and the promontory 211 can have in cross section a profile composed of a portion of a circle comprised between two rectilinear shoulders, respectively referenced 112 and 212.

On remarquera que ladite portion de cercle du profil de la rainure 111 et du promontoire 211 ne dépasse pas le demi-cercle, ce qui donne la possibilité à l'articulation métatarso-phalangienne prothétique de se luxer légérement afin d'absorber les contraintes dues aux chocs survenant lors de la marche et de préserver ainsi le composant métatarsien. It will be noted that said portion of the circle of the profile of the groove 111 and of the promontory 211 does not exceed the semicircle, which gives the prosthetic metatarsophalangeal joint the possibility of luxating slightly in order to absorb the stresses due to shocks occurring during walking and thus preserving the metatarsal component.

On peut observer sur les figures 1 et 28 que le composant métatarsien 100 compote ure quille 120 d'ancrage lisse et de forme effilée. Cette forme particuliere donnée à la quille d'ancrage participe également à la stabilisation à long terme du composant métatarsien 100 puisqu'elle a pour effet de préserver le stock osseux concerné. L'os étant présent en plus grande quantité, le vieillissement sera moins rapide.  It can be observed in FIGS. 1 and 28 that the metatarsal component 100 compotes a keel 120 of smooth anchoring and of tapered shape. This particular shape given to the anchoring keel also participates in the long-term stabilization of the metatarsal component 100 since it has the effect of preserving the bone stock concerned. The bone being present in greater quantity, aging will be slower.

La quille 120 d'ancrage ainsi que le bouclier 110 de frottement peuvent être réalisés dans un matériau métallique, tandis que le composant phalangien 200 est réalisé de préférence dans un matériau plastique tel que du polyéthylène.  The anchoring keel 120 as well as the friction shield 110 can be made of a metallic material, while the phalangeal component 200 is preferably made of a plastic material such as polyethylene.

Comme le montrent les figures 1, 3a à 3c, le composant phalangien 200 comporte une quille 220 d'ancrage munieS de façon classique, d'ailettes 221 rendues pliables du fait de leur division en une pluralité, ici 16, lamelles sectorielles 222.  As shown in FIGS. 1, 3a to 3c, the phalangeal component 200 comprises a keel 220 for anchoring conventionally provided with fins 221 made foldable due to their division into a plurality, here 16, sectoral strips 222.
