Description

Tête d'articulation Dour élément orothétiaue. Dour orothétiaue joint head element.

Plus particulièrement, mais non limitativement, I'invention concerne une tête d'articulation destinée à coopérer avec une tige humérale d'une prothèse d'épaule. More particularly, but not exclusively, the invention relates to a joint head designed to cooperate with a humeral stem of a shoulder prosthesis.

Généralement, avec ce type d'élément prothétique, il est nécessaire de pouvoir régler en hauteur, la tête d'articulation par rapport à la tige. Generally, with this type of prosthetic element, it is necessary to be able to adjust the height, the joint head relative to the stem.

A ce jour, les moyens employés pour obtenir ce réglage, ne sont pas satisfaisants et nécessitent très souvent, I'utilisation de plusieurs têtes, avec des tiges d'ancrage de longueurs différentes. To date, the means employed to achieve this setting, are not satisfactory and require very often, the use of several heads with anchor rods of different lengths.

L'invention s'est fixée pour but de remédier à ces inconvénients, d'une manière simple, sûre et efficace. The invention is set to remedy these drawbacks in a simple, safe and effective.

Pour résoudre le problème posé d'obtenir un réglage en hauteur, simple et précis, en utilisant une seule tête d'articulation, cette dernière est équipée d'une tige qui présente des agencements aptes à coopérer successivement avec un moyen de blocage en position monté dans l'élément prothétique, en communication avec la partie complémentaire recevant la tige. To solve the problem of obtaining a height adjustment, simple and precise, using a single joint head, the latter is equipped with a rod which has arrangements capable of cooperating successively with a mounted position locking means in the prosthetic element, in communication with the supplementary part receiving the rod.

Avantageusement, les agencements sont constitués par des empreintes en creux décalées en hauteur. Advantageously, the arrangements consist of hollow indentations offset in height. Les empreintes peuvent également être décalées angulairement. Impressions may also be angularly offset.

Pour résoudre le problème posé d'assurer le blocage en position de l'ensemble de la tête d'articulation par rapport à l'élément prothétique, le moyen de blocage est constitué par une vis coopérant avec l'une des empreintes en creux. To solve the problem of ensuring the blocking in position of the assembly of the joint head relative to the prosthetic element, the blocking means consists of a screw cooperating with one of the indentations.

Avantageusement, le fond des empreintes est tronconique en constituant un angle au centre de 90". Advantageously, the fingerprint base is tapered by forming a center angle of 90 ".

Un autre problème que se propose de résoudre l'invention est de pouvoir positionner, de manière optimale, la tête d'articulation dans la cavité cotyloïde correspondante, pour obtenir une restauration dans des conditions biomécaniques optimales. Another problem to be solved by the invention is able to position, optimally, the joint head in the corresponding acetabulum, to obtain a restoration in optimal biomechanical conditions.

Pour résoudre un tel problème, la tige est désaxée par rapport au centre du corps de la tête. To solve such a problem, the rod is offset relative to the center of the body of the head.

Cette désaxation notamment du haut vers le bas permet un raccordement optimal entre la partie supérieure de la tête et la partie supérieure humérale, pour obtenir une bonne continuité de forme, en éliminant tout problème de gêne mécanique au niveau de la coiffe des rotateurs. This malalignment including from top to bottom allows an optimal connection between the upper portion of the humeral head and the upper part, to obtain a good continuity of form, eliminating any mechanical discomfort problem at the rotator cuff.

L'invention est exposée ci-après plus en détail à l'aide des dessins annexés, dans lesquels: The invention is described below in more detail in the accompanying drawings, wherein:
La figure 1 est une vue en perspective de la tête d'articulation dans le cas d'une tige humérale. Figure 1 is a perspective view of the joint head seen in the case of a humeral stem.

La figure 2 est une vue en coupe et à grande échelle de la tête d'articulation. Figure 2 is a sectional view on a large scale of the joint head.

La figure 3 montre le montage de la tête d'articulation au niveau de la partie proximale d'un élément huméral. 3 shows the mounting of the joint head at the proximal portion of a humeral component.

La figure 4 montre, par une vue à caractère schématique, Figure 4 shows a schematic view,
I'impaction d'un élément prothétique huméral. I'impaction a prosthetic humeral component.

On a illustré aux figures des dessins, une tête d'articulation hémisphérique (1), destinée à coopérer avec un élément prothétique (2), sous forme d'une tige humérale. Is illustrated in the figures of the drawings, a hemispherical articulation head (1), intended to cooperate with a prosthetic element (2) in the form of a humeral stem. Cet exemple ne doit cependant pas être considéré comme limitatif, étant donné que l'invention concerne tout type de tête d'articulation destinée à coopérer avec un élément prothétique quelconque. This example should not, however, be considered limiting, since the invention relates to any type of joint head intended to cooperate with any prosthetic element.

La tête (1) présente une tige (la), destinée à être engagée dans un logement de forme complémentaire (2a), formé dans la partie proximale de l'élément (2). The head (1) has a shank (la), intended to be engaged in a housing of complementary shape (2a) formed in the proximal portion of the element (2). La tige (la) est de section cylindrique, le logement (2a) constituant un alésage. The shank (la) is cylindrical in section, the housing (2a) forming a bore.

Suivant l'invention, la tige (la) présente une série d'empreintes en creux (lai), décalées en hauteur. According to the invention, the rod (la) has a series of indentations (lai), offset in height. Ces empreintes (lai) peuvent également être décalées angulairement sur la périphérie de la tige (la), pour augmenter les possibilités de réglage. These fingerprints (Ia) can also be angularly displaced on the periphery of the shaft (la), to increase the adjustment possibilities.

Une vis de blocage (3) est engagée dans l'élément prothétique (2), en étant en communication avec l'alésage (2a), pour coopérer avec l'une quelconque des empreintes (lai). A locking screw (3) is engaged in the prosthetic element (2), being in communication with the bore (2a), to cooperate with any one of indentations (lai).

On conçoit donc, qu'en fonction de l'engagement de la vis (3) avec l'une ou l'autre des empreintes (lai), on obtiendra différents réglages en hauteur de l'ensemble de la tête (1) par rapport à l'élément (2). It is therefore conceivable that, depending on the engagement of the screw (3) with one or the other of the recesses (lai), one will obtain variable height adjustment of the head assembly (1) relative to the element (2). A noter que chacune des empreintes est tronconique, en constituant un angle au centre de 90". Note that each of the recesses is tapered, constituting a center angle of 90 ".

Suivant une autre caractéristique importante de l'invention, la tige (la) est désaxée par rapport au centre de la tête d'articulation (figure 2) Plus particulièrement, ce désaxage est déterminé pour décaler vers le bas, la tête d'articulation. According to another important feature of the invention, the rod (Ia) is offset relative to the center of the joint head (2) More particularly, this misalignment is determined for shift down, the joint head. Ces dispositions s'avèrent particulièrement interessantes dans le cas d'une prothèse humérale, pour assurer un These provisions are particularly interesting in the case of a humeral prosthesis, to ensure
raccordement optimum, entre la partie supérieure de la tête (1) et la partie optimum connection between the upper part of the head (1) and the part
supérieure de l'élément huméral en assurant une bonne continuité, top of the humeral element ensuring good continuity,
supprimant toute gêne mécanique sur la coiffe des rotateurs. removing any mechanical impediment to the rotator cuff.

Les avantages ressortent bien de la description. The advantages are apparent from the description.
