Description

On connaît par le FR - A - 2 619 502, une prothèse céphalique ou totale d'épaule en matière répondant aux normes actuelles en chirurgie orthopédique
Cette prothèse se caractérise par le fait que la tige d'ancrage humérale de forme cylindrique légèrement tronconique; en général à section en étoile; présente un prolongement sensiblement cylindro-tronconique pourvu d'une saignée inférieure destinée à recevoir un cran mâle prévu dans un dégagement tronconique percé dans la face inférieure de la tête d'humérus affectant une forme demi-sphérique ou demi-cylindrique ; puis, sur la partie supérieure du prolongement de la tige d'ancrage cylindrique, sont percés des trous pour le rattachement des muscles sur cette tige.We know from FR - A - 2 619 502, a cephalic or total shoulder prosthesis in material meeting current standards in orthopedic surgery
This prosthesis is characterized by the fact that the humeral anchor rod of cylindrical shape slightly frustoconical; generally star-shaped; has a substantially cylindrical-frustoconical extension provided with a lower groove intended to receive a male notch provided in a frustoconical recess pierced in the underside of the humerus head affecting a semi-spherical or semi-cylindrical shape; then, on the upper part of the extension of the cylindrical anchor rod, holes are drilled for the attachment of the muscles on this rod.

Mais, dans bien des cas, la glenne humérale située à l'extrémité externe de l'omoplate est également endommagée et nécessite une prothèse. However, in many cases, the humeral gland located at the outer end of the scapula is also damaged and requires a prosthesis.

Une étude a permis, en tenant compte des impératifs naturels de l'épaule, de créer, en plus de la tête humérale, une prothèse pour la glenne humérale afin d'obtenir un ensemble pratiquement cohérent permettant une remise en état parfait de l'articulation de l'épaule du patient. A study made it possible, taking into account the natural imperatives of the shoulder, to create, in addition to the humeral head, a prosthesis for the humeral glen in order to obtain a practically coherent whole allowing a perfect restoration of the joint of the patient's shoulder.

La présente invention a donc pour objet une prothèse humérale coopérant avec la prothèse d'épaule. The present invention therefore relates to a humeral prosthesis cooperating with the shoulder prosthesis.

Conformément à l'invention, la prothèse pour la glenne humérale destinée à coopérer avec une prothèse céphalique ou totale d'épaule est caractérisée en ce qu'elle est constituée par une embase en forme de plaque trapézoïdale à bords superieur et inférieur de forme en arc de cercle présentant un rebord circulaire relevé à 90" comportant des saignées haute et basse. cette embase étant percée d'au moins de trous oblongs pour le passage de vis à tête bombée tandis que la face arrière de l'embase comporte un plot de fixation, cette embase étant recouverte par une pièce de glissement de forme correspondante présentant sur sa face arrière des protubérances de fixation sur l'embase par pénétration dans les saignées et des évidements à bords arrondis pour le logement des têtes des vis tandis que la face avant de la pièce de glissement comporte un évidement de forme elliptique concave dont la partie haute déborde de la partie basse en formant ainsi un toit destiné à permettre une bonne rotation de la tête d'humérus de la prothèse céphalique. According to the invention, the prosthesis for the humeral glenoid intended to cooperate with a cephalic or total shoulder prosthesis is characterized in that it is constituted by a base in the form of a trapezoidal plate with upper and lower edges of arc form. of circle having a circular rim raised to 90 "having high and low grooves. this base being pierced with at least oblong holes for the passage of domed head screws while the rear face of the base comprises a fixing stud , this base being covered by a sliding part of corresponding shape having on its rear face fixing protuberances on the base by penetration in the grooves and recesses with rounded edges for housing the heads of the screws while the front face of the sliding part has a concave elliptical recess, the upper part of which extends beyond the lower part, thus forming a it is intended to allow good rotation of the humerus head of the cephalic prosthesis.

Suivant une autre caractéristique de l'invention, la face arrière de l'embase est revêtue de métal poreux, d'un fin treillis métallique ou d'un autre revêtement compatible avec le corps humain avec ou sans adjonction de H A P (hydroxylapatite) facilitant l'accrochage de la prothèse sur l'os. According to another characteristic of the invention, the rear face of the base is coated with porous metal, a fine metal mesh or another coating compatible with the human body with or without the addition of PAH (hydroxylapatite) facilitating the hanging of the prosthesis on the bone.

Diverses autres caractéristiques ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée à titre d'exemple non limitatif, aux dessins annexés. An embodiment of the object of the invention is shown by way of non-limiting example, in the accompanying drawings.

La fig. 1 est une vue de face avant de l'embase de la prothèse de glenne. Fig. 1 is a front view of the base of the glenoid prosthesis.

La fig. 2 est une coupe longitudinale de la fig. Fig. 2 is a longitudinal section of FIG.

1 suivant la ligne II-II.1 along line II-II.

La fig. 3 est une vue, à plus grande échelle, montrant la fixation de l'embase de la prothèse au moyen de vis du type à ostéosynthèse humaine. Fig. 3 is a view, on a larger scale, showing the fixing of the base of the prosthesis by means of screws of the human osteosynthesis type.

La fig. 4 est une vue de la face avant de la partie avant de la prothèse destinée à coopérer avec la prothèse humérale. Fig. 4 is a view of the front face of the front part of the prosthesis intended to cooperate with the humeral prosthesis.

La fig. 5 est une vue de la face arrière correspondant a la fig. 4. Fig. 5 is a view of the rear face corresponding to FIG. 4.

La fig. 6 est une coupe suivant la ligne VI-VI de la fig. 4.  Fig. 6 is a section along the line VI-VI of FIG. 4.

La fig. 7 est un schéma montrant la prothèse de glenne montée sur une omoplate humaine. Fig. 7 is a diagram showing the glenoid prosthesis mounted on a human scapula.

A la fig. 1, on a représenté la face avant de l'embase de la prothèse de glenne qui est constituée par une plaque 1 de forme sensiblement trapézoïdale à borts supérieur la et inférieur 1k de forme en arc de cercle présentant un rebord circulaire relevé 2 à 90 qui comporte des saignées 3. (Voir fig. 2). In fig. 1, there is shown the front face of the base of the glenoid prosthesis which is constituted by a plate 1 of substantially trapezoidal shape with upper and lower bows 1k of arcuate shape having a raised circular edge 2 to 90 which has grooves 3. (See fig. 2).

La partie arrière de la plaque 1 est munie d'un plot 4 destiné à être placé pour centrer et fixer d'une manière biomécanique l'embase de la prothèse. The rear part of the plate 1 is provided with a stud 4 intended to be placed to center and fix in a biomechanical manner the base of the prosthesis.

Ce plot 4 peut avoir une forme cylindrique ou autre. This stud 4 can have a cylindrical or other shape.

On peut également mentionner que la surface arrière 1ç de la plaque 1 ainsi que le plot 4 peuvent être revêtus de métal poreux, d'un fin treillis métallique ou d'un autre revêtement avec ou sans adjonction de H A P (hydroxylapatite) permettant une fixation aisée de cette embase de prothèse sur l'os. It may also be mentioned that the rear surface 1c of the plate 1 as well as the stud 4 can be coated with porous metal, with a fine metal mesh or with another coating with or without the addition of PAH (hydroxylapatite) allowing easy fixing. of this prosthesis base on the bone.

De plus, le fond 1ç de la plaque 1 est percé de trous oblongs 6, 7 pour fixer cette embase de prothèse au moyen de vis 8 du type ostéosynthèse humaine à tête bombée 9 qui permettent ainsi avec les trous oblongs 6 et 7 un dégagement angulaire de 90 à 45" pour un bon fonctionnement de l'épaule du patient. In addition, the bottom 1c of the plate 1 is pierced with oblong holes 6, 7 to fix this prosthesis base by means of screws 8 of the human osteosynthesis type with a domed head 9 which thus allow with the oblong holes 6 and 7 an angular clearance. from 90 to 45 "for proper functioning of the patient's shoulder.

Cette plaque 1 est revêtue d'une pièce 11 dite pièce de glissement voir fig. 4 à 6 qui présente sur sa face arrière 11g des évidements à bords arrondis 12, 13 destinés à coopérer avec les têtes bombées des vis 8. This plate 1 is coated with a part 11 called a sliding part, see fig. 4 to 6 which has on its rear face 11g recesses with rounded edges 12, 13 intended to cooperate with the domed heads of the screws 8.

De plus, la face arrière présente des saignées 14, 15 permettant de fixer la pièce 11 de glissement sur la embase 1 d'une manière simple et efficace en engageant les protubérances 16 naturellement dans les saignées 3 de la embase 1.  In addition, the rear face has grooves 14, 15 making it possible to fix the sliding part 11 on the base 1 in a simple and effective manner by engaging the protrusions 16 naturally in the grooves 3 of the base 1.

On obtient ainsi une excellente mise en place de la pièce de glissement 11 sur la plaque 1. La face avant de cette pièce de glissement 11 comporte un évidement 18 de forme élliptique concave mais de façon que la partie haute 18g déborde de la partie basse 18b en formant ainsi un toit destiné à permettre une bonne rotation de la tête d'humérus, en général de forme semi-cylindrique ou semi-sphérique 30 comme cela est visible à la fig. 7. An excellent positioning of the sliding piece 11 is thus obtained on the plate 1. The front face of this sliding piece 11 has a recess 18 of concave elliptical shape but so that the upper part 18g projects beyond the lower part 18b thereby forming a roof intended to allow good rotation of the humerus head, generally of semi-cylindrical or semi-spherical shape 30 as can be seen in FIG. 7.

I1 y a lieu également de signaler que l'embase 1 est réalisée, le plus souvent; en un alliage métallique ou en une autre matière bio-compatible avec le corps humain tandis que la pièce de glissement 11 est réalisée en d'autres matériaux mais en particulier en polyuréthane haute densité, en céramique, en carbone composite, etc. I1 should also be reported that the base 1 is made, most often; in a metallic alloy or in another material which is bio-compatible with the human body while the sliding part 11 is made of other materials but in particular of high density polyurethane, ceramic, carbon composite, etc.

Finalement, il y a lieu également de mentionner qu'il est prévu en 20 dans la pièce de glissement 11 une petite tige métallique placée à la partie supérieure de cette pièce de glissement afin d'obtenir un repère radiologique. Finally, it should also be mentioned that there is provided at 20 in the sliding part 11 a small metal rod placed at the top of this sliding part in order to obtain a radiological reference.

I1 est à remarquer que cette prothèse de glenne présente donc les avantages suivants
a) Une embase métallique sertissant la piece de glissement en matière plastique synthéthique,
b) une possibilité de démontage;
c) le réglage de l'angulation des vis,
d) un revêtement pour la fixation bio-mécanique. It should be noted that this glenoid prosthesis therefore has the following advantages
a) A metal base crimping the sliding part in synthetic plastic,
b) a possibility of disassembly;
c) adjusting the angulation of the screws,
d) a coating for bio-mechanical fixing.
