Abstract

The implant comprises a metallic base (1) having fixings into a part of the limb. The base receives a polyethylene insert (2). The base has a reduced thickness without a peripheral rim and has a profile and fittings engaging complementary fittings of the insert enabling its coupling and angular indexation. The profile (1c) of the base located on the lower side engages with a groove section that has a part (2b) formed in the overhang of the insert under face in order to obtain locking. The base has pins (3,4) able to be engaged in holes (2e) in the insert.

Description

L'invention se rattache au secteur technique des implantsThe invention relates to the technical sector of implants

orthopédiques, notamment des prothèses d'épaule.  orthopedic, including shoulder prostheses.

Plus généralement, l'invention concerne tout type d'implants  More generally, the invention relates to any type of implant

prothétiques pour l'articulation d'un membre anatomique, l'implant étant du type de ceux comprenant une embase métallique présentant des agencements de fixation dans la partie du membre anatomique prothésé, ladite embase étant destinée à recevoir, d'une manière fixe, un insert en 10 polyéthylène.  prosthetics for the articulation of an anatomical limb, the implant being of the type comprising those of a metal base having fixing arrangements in the part of the prosthetic anatomical member, said base being intended to receive, in a fixed manner, a polyethylene insert.

A titre d'exemple indicatif, nullement limitatif, dans le cas d'une prothèse d'épaule, cette dernière comprend, essentiellement, un élément huméral et un élément glénodien. L'élément huméral est destiné à être fixé 15 dans la diaphyse humérale, tandis que l'élément glénodien est destiné à être fixé au niveau de la glène de l'omoplate. Le plus souvent, l'élément glénodien présente un plateau ou insert en polyéthylène, fixé sur une embase support présentant tout type d'agencement pour être ancré sans ciment au niveau de la glène de l'omoplate. 20 L'embase en polyéthylène peut délimiter une surface d'appui et de glissement, de profil concave, pour coopérer avec une tête humérale de profil complémentaire convexe. On n'exclut pas une conception inverse de l'ensemble prothétique, à savoir une embase de forme générale 25 hémisphérique en vue de constituer une tête d'articulation coopérant, dans ce cas, avec une surface d'appui et de glissement que présente, directement  By way of example, in no way limiting, in the case of a shoulder prosthesis, the latter essentially comprises a humeral element and a glenodian element. The humeral element is intended to be fixed in the humeral shaft, while the glenodian element is intended to be fixed at the level of the glenoid of the scapula. Most often, the glenodian element has a polyethylene tray or insert, fixed to a support base having any type of arrangement to be anchored without cement at the glenoid of the scapula. The polyethylene base can delimit a support and sliding surface, of concave profile, to cooperate with a humeral head of convex complementary profile. A reverse design of the prosthetic assembly is not excluded, namely a generally hemispherical base 25 in order to constitute a joint head cooperating, in this case, with a bearing and sliding surface that presents, directly

ou d'une manière rapportée, l'élément huméral correspondant.  or in a reported manner, the corresponding humeral element.

Quel que soit le profil en section de l'insert en polyéthylène, ce dernier est généralement clipé dans un évidement de forme complémentaire que présente l'embase métallique délimité par un rebord périphérique. Ce  Whatever the profile in section of the polyethylene insert, the latter is generally clipped into a recess of complementary shape that has the metal base delimited by a peripheral rim. This

rebord enserre, totalement ou partiellement, l'insert en polyéthylène.  rim completely or partially encloses the polyethylene insert.

De tels agencements de construction sont acceptables dans le cas d'une prothèse d'articulation du genou, mais le sont beaucoup moins pour une prothèse d'articulation de l'épaule. En effet, le dimensionnement de l'embase support étant limité, des risques d'usure antérieure et surtout postérieure de l'insert peuvent apparaître du fait de la faible épaisseur sur 10 les rebords. On constate des usures postérieures sur des arthroses sur  Such construction arrangements are acceptable in the case of a knee joint prosthesis, but are much less so for a shoulder joint prosthesis. Indeed, the dimensioning of the support base being limited, risks of anterior and especially posterior wear of the insert may appear due to the small thickness on the edges. There is posterior wear on arthrosis on

dysplasie, à cause de la rétroversion du col de glène. Bien évidemment, comme indiqué, un tel problème apparaît essentiellement dans le cas d'un implant glénodien présentant une embase support métallique fixée sans ciment au moyen, par exemple, de vis dans la cavité glénoidienne de 15 l'omoplate.  dysplasia, due to retroversion of the glenoid neck. Obviously, as indicated, such a problem appears essentially in the case of a glenodian implant having a metal support base fixed without cement by means, for example, of screws in the glenoid cavity of the scapula.

L'invention s'est fixée pour but de remédier à ces inconvénients, de  The object of the invention is to remedy these drawbacks,

manière simple, sre, efficace et rationnelle.  simple, safe, efficient and rational way.

Le problème que se propose de résoudre l'invention est d'éviter tout problème d'usure, notamment dans le cas d'une prothèse de l'épaule o le support de glène est fixé sans ciment. On doit rappeler que l'invention trouve une application générale pour tout type d'implants prothétiques comprenant une embase support métallique recevant, d'une manière fixe, un 25 insert en polyéthylène, en particulier pour les embases tibiales de prothèse  The problem which the invention proposes to solve is to avoid any problem of wear, in particular in the case of a shoulder prosthesis where the glenoid support is fixed without cement. It should be remembered that the invention finds general application for all types of prosthetic implants comprising a metal support base receiving, in a fixed manner, a polyethylene insert, in particular for the tibial prosthesis bases.

du genou unicompartimentale.of the unicompartmental knee.

Pour résoudre un tel problème, il a été conçu et mis au point un implant orthopédique dans lequel l'embase est d'épaisseur réduite et présente un profil et des agencements coopérant avec des agencements complémentaires de l'insert pour permettre son accouplement et son 5 indexation angulaire, lesdits agencements étant aptes à permettre l'intégration de ladite embase, de manière à ce que ledit insert en déborde  To solve such a problem, an orthopedic implant has been designed and developed in which the base is of reduced thickness and has a profile and arrangements cooperating with arrangements complementary to the insert to allow its coupling and its 5 angular indexing, said arrangements being able to allow the integration of said base, so that said insert projects beyond it

au moins du côté inférieur et surtout des côtés antérieur et postérieur.  at least on the lower side and especially on the anterior and posterior sides.

Pour résoudre le problème posé d'assurer la liaison sure et efficace 10 entre le support métallique et l'insert en polyéthylène, le profil de l'embase  To solve the problem posed of ensuring a safe and efficient connection 10 between the metal support and the polyethylene insert, the profile of the base

est situé du côté inférieur et coopère avec une rainure profilée que présente une partie formée en débordement de la face de dessous de l'insert pour obtenir un effet de verrouillage, ladite embase présentant des plots aptes à être engagés dans des trous formés dans l'épaisseur de l'insert, à partir de sa 15 face de dessous.  is located on the lower side and cooperates with a profiled groove that has a portion formed in overflow from the underside of the insert to obtain a locking effect, said base having studs capable of being engaged in holes formed in the thickness of the insert, from its underside.

Pour améliorer l'effet de clipage, les plots présentent une tête débordante. Pour résoudre le problème posé d'assurer l'indexation angulaire de l'insert en polyéthylène par rapport à l'embase support, la face d'appui de l'embase recevant l'insert présente au moins une nervure longitudinale coopérant avec une rainure complémentaire formée à partir de la face de  To improve the clipping effect, the studs have an overhanging head. To resolve the problem posed of ensuring the angular indexing of the polyethylene insert relative to the support base, the bearing face of the base receiving the insert has at least one longitudinal rib cooperating with a complementary groove formed from the face of

dessous de l'insert.below the insert.

Pour résoudre le problème posé d'améliorer la fixation de l'embase support métallique au niveau de la cavité glénodienne, dans le cas d'une prothèse d'épaule, la face d'appui de l'embase recevant l'insert présente, du côté supérieur, une patte support de fixation dont une partie coopère avec  To solve the problem posed of improving the fixing of the metal support base at the level of the glenodian cavity, in the case of a shoulder prosthesis, the bearing face of the base receiving the present insert, upper side, a fixing support lug, part of which cooperates with

une empreinte complémentaire de l'insert.  an additional imprint of the insert.

Pour résoudre le problème posé d'offrir une fixation stable de  To solve the problem of offering a stable fixation of

l'embase support métallique par rapport à la cavité glénodienne, la face de dessous de l'embase coopérant avec la partie du membre anatomique, présente un plot d'ancrage pour l'engagement d'une vis de fixation. La face de dessous présente un profil arrondi pour correspondre à celui de la partie 10 du membre anatomique.  the metal support base relative to the glenodian cavity, the underside of the base cooperating with the part of the anatomical member, has an anchoring stud for the engagement of a fixing screw. The underside has a rounded profile to match that of part 10 of the anatomical member.

L'insert présente une face d'appui et de glissement concave apte à coopérer avec une forme complémentaire d'un autre implant prothétique rendu solidaire de l'autre partie du membre anatomique prothésé. 15 L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels: - la figure 1 est une vue en perspective considérée de dessus, d'une forme de réalisation.de l'implant prothétique dans le cas d'une application à 20 un implant glénodien, l'insert en polyéthylène étant représenté avant fixation sur l'embase support métallique; - la figure 2 est une vue correspondant à la figure 1 considérée de dessous; - la figure 3 est une vue semblable à la figure 2, après fixation de 25 l'insert en polyéthylène sur l'embase métallique support; - la figure 4 est une vue en coupe longitudinale de l'ensemble prothétique selon la figure 3; - la figure 5 est une vue montrant l'impaction de l'ensemble prothétique dans le cas d'une application à une prothèse d'articulation de l'épaule. L'implant prothétique est du type de ceux comprenant une embase  The insert has a concave bearing and sliding face capable of cooperating with a shape complementary to another prosthetic implant made integral with the other part of the prosthetic anatomical member. The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is a perspective view seen from above, of an embodiment of the prosthetic implant in in the case of an application to a glenodian implant, the polyethylene insert being shown before attachment to the metal support base; - Figure 2 is a view corresponding to Figure 1 seen from below; - Figure 3 is a view similar to Figure 2, after fixing the polyethylene insert on the metal support base; - Figure 4 is a longitudinal sectional view of the prosthetic assembly according to Figure 3; - Figure 5 is a view showing the impaction of the prosthetic assembly in the case of an application to a shoulder joint prosthesis. The prosthetic implant is of the type comprising a base

support métallique (1) et un insert en polyéthylène (2).  metal support (1) and a polyethylene insert (2).

Dans l'exemple illustré, l'embase support (1) est destinée à être fixée au niveau de la glène (G) de l'omoplate, représentée schématiquement à la 10 figure 5. Selon l'invention, l'embase (1) est d'épaisseur réduite, sans rebord périphérique, et présente un profil et des agencements aptes à permettre l'accouplement de l'insert (2) pour permettre l'intégration de ladite embase, de manière à ce que l'insert (2) en déborde au moins du côté inférieur et surtout des côtés antérieur et postérieur. 15 Dans ce but, l'embase support (1) présente une face d'appui plane  In the example illustrated, the support base (1) is intended to be fixed at the level of the glenoid (G) of the scapula, shown schematically in FIG. 5. According to the invention, the base (1) is of reduced thickness, without peripheral rim, and has a profile and arrangements suitable for allowing the coupling of the insert (2) to allow the integration of said base, so that the insert (2) at least extends beyond it on the lower side and especially on the anterior and posterior sides. 15 For this purpose, the support base (1) has a flat bearing face

(la) destinée, comme il sera indiqué dans la suite de la description, à recevoir l'insert en polyéthylène (2). La face de dessous (lb) de l'embase support (1) est convexe pour épouser sensiblement la forme de la cavité 20 glénodienne. Cette face convexe (lb) est raccordée tangentiellement au  (la) intended, as will be indicated in the following description, to receive the polyethylene insert (2). The underside (lb) of the support base (1) is convex to substantially match the shape of the glenodian cavity. This convex face (lb) is tangentially connected to the

niveau des bords latéraux de la face plane (la). Le bord transversal inférieur (lc) de l'embase (1) est arrondi et coopère avec une rainure profilée (2a) que présente une partie (2b) formée en débordement de la face de dessous de l'insert (2). A l'opposé, c'est-à-dire du côté supérieur, la face d'appui 25 (la) de l'embase (1) présente deux plots alignés transversalement (3) et (4) présentant chacun une tête débordante profilée (3a), (4a). Les plots (3) et (4) sont destinés à être engagés dans des trous épaulés (2c) et (2d) formés dans l'épaisseur de l'insert (2) à partir de sa face de dessous (2e) coopérant en  level of the lateral edges of the flat face (la). The lower transverse edge (lc) of the base (1) is rounded and cooperates with a profiled groove (2a) that has a part (2b) formed in overflow from the underside of the insert (2). In contrast, that is to say on the upper side, the bearing face 25 (la) of the base (1) has two studs aligned transversely (3) and (4) each having a profiled projecting head (3a), (4a). The studs (3) and (4) are intended to be engaged in shouldered holes (2c) and (2d) formed in the thickness of the insert (2) from its bottom face (2e) cooperating in

appui avec la face plane (la) de l'embase métallique (1).  support with the flat face (la) of the metal base (1).

Après engagement du bord transversal (lc) de l'embase (1) dans la 5 rainure (2a) sous un effet de basculement angulaire et en exerçant un effort de pression au niveau des plots (3) et (4), on obtient un accouplement par clipage de l'insert (2) sur l'embase métallique (1). A noter que, pour améliorer l'ancrage, la rainure (2a) est profilée notamment en forme de biseau. La partie débordante (2b), à partir de laquelle est formée la rainure profilée (2a), constitue un nez profilé en section pour recouvrir le rebord transversal inférieur (lc) de l'embase (1). La face interne (2bl) de ce nez est profilée d'une manière concave pour coopérer en appui avec une branche 15 équerrée arrondie (ld) apte à coopérer avec le pilier de l'omoplate. Cette branche (ld) est formée en débordement de la face de dessous (lb) de l'embase métallique (1). Les bords antérieur et postérieur de l'insert (2)  After engagement of the transverse edge (lc) of the base (1) in the groove (2a) under an angular tilting effect and by exerting a pressure force at the studs (3) and (4), a coupling by clipping the insert (2) onto the metal base (1). Note that, to improve the anchoring, the groove (2a) is profiled in particular in the form of a bevel. The projecting part (2b), from which the profiled groove (2a) is formed, constitutes a profiled nose in section to cover the lower transverse rim (lc) of the base (1). The internal face (2bl) of this nose is profiled in a concave manner to cooperate in abutment with a rounded squared branch (ld) able to cooperate with the pillar of the scapula. This branch (ld) is formed in overflow from the underside (lb) of the metal base (1). The anterior and posterior edges of the insert (2)

débordent de ceux de l'embase (1).protrude from those of the base (1).

Pour assurer l'indexation angulaire de l'insert (2) par rapport à l'embase (1), la face de dessus (la) présente, suivant son axe médian, une nervure (I e) apte à recevoir une rainure complémentaire (2f) formée à partir  To ensure the angular indexing of the insert (2) relative to the base (1), the top face (la) has, along its median axis, a rib (I e) capable of receiving a complementary groove ( 2f) formed from

de la face de dessous (2e) de l'insert (2).  from the underside (2e) of the insert (2).

On peut noter également que la face d'appui (la) de l'embase (1)  It can also be noted that the bearing face (la) of the base (1)

peut présenter, du côté supérieur, une patte support (If) présentant des agencements de fixation (lfl) avec le pilier de la coracode par exemple.  may have, on the upper side, a support tab (If) having fixing arrangements (lfl) with the pillar of the coracode for example.

Cette patte est formée en débordement de la face (la) et est engagée dans l'épaisseur d'une empreinte de forme complémentaire (2g) formée à partir  This tab is formed in overflow from the face (la) and is engaged in the thickness of an imprint of complementary shape (2g) formed from
