Description

SYSTEME DE PROTHESE D'EPAULE SYSTEM PROSTHETIC SHOULDER
La présente invention concerne un système de prothèse d'épaule perfectionnée, lequel système permet une adaptation de la prothèse en fonction de chaque cas particulier. The present invention relates to a perfected shoulder prosthesis system, which system allows an adaptation of the prosthesis depending on each particular case.

L'évolution des matériaux et des techniques chirurgicales a permis, depuis quelques années, le développement des prothèses d'épaule. The evolution of materials and surgical techniques have, in recent years the development of shoulder prostheses. Celles-ci sont actuellement implantées dans deux indications majeures, l'une en pathologie traumatique et l'autre en orthopédie. They are currently based in two major indications, one in traumatic pathology and one in orthopedics.

En pathologie traumatique, il s'agit de traiter des fractures comminutives de l'extrémité supérieure de l'humérus, et essentiellement les fractures céphalo tubérositaires à quatre fragments : l'un est constitué par la calotte de tête vouée à la nécrose, le deuxième par le trochiter détaché portant la coiffe, le troisième par le trochin portant le sous-scapulaire, et le quatrième par la diaphyse humérale. In traumatic pathology, it comes to treating comminuted fractures of the upper end of the humerus, and essentially the cerebrospinal tuberosity fracture four fragments: one consisting of the head cover dedicated to necrosis, the second the detached trochiter bearing the cap, the third by the lesser tuberosity bearing the subscapularis, and the fourth by the humeral diaphysis. Dans cette indication, la prothèse se limite à une seule pièce humérale comprenant une tige d'ancrage dans l'humérus et un élément céphalique ou tête humérale. In this indication, the prosthesis is limited to a single humeral component comprising an anchor stem into the humerus and a cephalic element or humeral head.

En orthopédie, la mise en place d'une prothèse d'épaule est conséquente soit à des séquelles traumatiques avec cals vicieux, soit à des omarthroses. In orthopedics, the establishment of a shoulder prosthesis is consistent either with sequelae of traumatic malunion or to omarthroses. Celles-ci sont fréquemment dues à une rupture de coiffe ancienne, ou bien encore liées à une polyarthrite rhumatoide. These are frequently due to a break in old cap, or even related to rheumatoid arthritis.

Dans les deux cas, l'absence de coiffe entraîne généralement une arthrose excentrée avec surélévation de l'humérus par rapport à la glène qui est le plus souvent le siège d'un éculement supérieur. In both cases, the absence of cap usually causes an eccentric osteoarthritis with elevation of the humerus relative to the glenoid is most often the site of a superior éculement. Il y a alors nécessité de poser une prothèse totale, c'est-à-dire une prothèse comprenant la pièce humérale déjà mentionnée, ainsi qu'une pièce glénoidienne fixée sur l'omoplate. There then need to ask a total prosthesis, that is to say a prosthesis comprising a humeral component mentioned above, and a glenoid piece attached to the scapula.

Dans les prothèses connues de même type que celle de l'invention, la pièce humérale comprend entre la tige d'ancrage dans l'humérus et l'élément céphalique ou tête humérale une partie intermédiaire ou col faisant un angle de l'ordre de 1350 avec l'axe de la tige. In the known prostheses of the same type as that of the invention, the humeral component comprises between the anchor rod in the humerus and the cephalic or humeral head member an intermediate or neck portion forming an angle of the order of 1350 with the axis of the rod. A la jonction tige-col, des moyens sont prévus pour limiter l'enfoncement de la tige dans l'humérus, afin d'obtenir une qualité d'ancrage satisfaisante et durable. At the junction rod collar, means are provided for limiting the penetration of the stem into the humerus, in order to obtain a satisfactory and durable anchoring quality. Il s'agit par exemple d'une collerette destinée à venir en appui par sa face inférieure sur le bord de section de l'humérus. This is for example a flange intended to rest with its underside on the humerus section edge.

Un problème majeur rencontré par le chirurgien avec ce type de prothèse réside dans l'impossibilité d'en assurer un positionnement correct si les conditions telles qu'une fracture bas située lui imposent de couper lrhumérus au-dessous d'un certain niveau : il n'a alors le choix qu'entre deux alternatives aussi imparfaites l'une que l'autre : soit suspendre la prothèse en ne l'enfonçant que partiellement dans l'humérus, ce qui est source de descellement; A major problem faced by the surgeon with this type of prosthesis is the inability to ensure proper positioning if the conditions such as low fracture located require it to cut lrhumérus below a certain level: it n 'then has the choice between two alternative also imperfect to the other: suspend the prosthesis does pushing partially in the humerus, which is source of loosening; ou bien appuyer la prothèse sur le bord de section de l'humérus, ce qui entraîne le relâchement du deltolde et de la coiffe, avec diminution du bras de levier qui devient inadéquat pour l'abduction et l'élévation active efficaces. or press the prosthesis on the humerus section edge, resulting in the release of deltolde and cap, with decreasing lever arm becomes inadequate for abduction and effective active elevation.

L'objet de l'invention est de prévoir un nouveau système de prothèse d'épaule perfectionnée, notamment en vue d'apporter une solution simple au problème susénoncé. The object of the invention to provide a new advanced shoulder replacement system, in particular to provide a simple solution to the problem susénoncé.

A cet effet, un système de prothèse d'épaule selon l'invention, dont la pièce humérale comporte une tige d'ancrage dans l'humérus prolongée par un col intermédiaire faisant un angle de l'ordre de 1350 avec elle et portant la tête humérale, la partie supérieure de la tige présentant en outre des moyens pour limiter son enfoncement dans le canal médullaire de l'humérus, est caractérisé en ce que la tige et la tête humérale sont des éléments séparés, réunis au moyen d'une pièce intermédiaire orientée selon l'axe du col, et en ce qu'il est prévu un jeu de plusieurs pièces intermédiaires de longueurs différentes, afin de permettre, à partir d'une tige d'ancrage et d'une tête humérale données, de choisir la pièce intermédiaire procurant la longueur de col la plus proche de la valeur désirée. To this end, a shoulder prosthesis system according to the invention, the humeral component comprises an anchor rod in the extended humerus by an intermediate neck forming an angle of the order of 1350 with it and carrying the head humerus, the upper portion of the stem further having means for limiting its insertion into the medullary canal of the humerus, is characterized in that the stem and humeral head are separate members, joined by means of an intermediate piece oriented along the axis of the neck, and in that there is provided a set of several intermediate pieces of different lengths, in order, from an anchoring rod and a humeral head data to select the intermediate piece providing the length of the neck closest to the desired value.

Indépendamment des autres paramètres concernant la tige d'ancrage et la tête humérale, l'invention offre donc au chirurgien la possibilité de choisir en préopératoire la longueur de col en fonction de chaque cas particulier. Independently of other parameters concerning the anchor rod and the humeral head, the invention therefore provides the surgeon the ability to choose preoperatively the neck length depending on each particular case. Du fait de l'angle de 1350 entre la tige et le col, l'augmentation en longueur de celuici entraîne un déport vers l'extérieur de la tige humérale par rapport à l'élément céphalique, qui contribue d'une part à la remise en tension du deltoïde et de la coiffe, en augmentant d'autre part le bras de levier du deltoïde pour l'abduction. Due to the angle 1350 between the rod and collar, the increase in length of the latter causes an offset outwardly of the humeral stem with respect to the cephalic element which contributes a part in the delivery voltage deltoid and cap, increasing the deltoid on the other hand the lever arm for abduction.

L'invention sera mieux comprise à l'aide des explications qui vont suivre et des dessins annexés, dans lesquels The invention will be better understood using the following explanations and the accompanying drawings, wherein

Figs. 2a à 2c sont des vues schématiques représentant, partiellement en coupe, la partie supérieure de la pièce humérale, respectivement avec trois cols de longueurs différentes. 2a to 2c are schematic views showing, partially in section, the upper portion of the humeral component, respectively with three necks of different lengths.

Dans la prothèse totale représentée à la Fig. In total prosthesis shown in Fig. la, la pièce humérale 1 comprend une tige d'ancrage 2 limitée à sa partie supérieure par une collerette 3, une pièce intermédiaire 4 inclinée par rapport à la tige 2 pour former un col et, à l'extrémité supérieure de celle- ci, une tête humérale 5, laquelle est destinée à venir en contact intime par sa surface externe avec la surface concave correspondante d'une pièce glénoidienne 6 fixée à l'omoplate. the, the humeral component 1 comprises an anchor rod 2 limited at its upper part by a flange 3, an intermediate part 4 is inclined relative to the rod 2 to form a neck and, at the upper end thereof, a humeral head 5, which is intended to come into intimate contact by its outer surface with the corresponding concave surface of a glenoid piece 6 attached to the scapula.

La tige humérale 2, en matériau biocompatible tel que titane, présente un état de surface permettant une fixation sans ciment ou un scellement, cet état de surface consistant, par exemple, en la formation de fines pores. The humeral stem 2, biocompatible material such as titanium, has a surface state for cementless fixation or sealing, this surface state consisting of, for example, in the formation of fine pores. Elle est de forme presque cylindrique, avec deux petits méplats avant et arrière 7. It is almost cylindrical, with two small flats front and rear 7.

Au sommet de la tige 2, la collerette 3 est inclinée selon un angle de 45 , environ, par rapport à l'axe longitudinal XX, et au-delà de celle-ci, un plot 8 de type cone Morse fait saillie. At the top of the rod 2, the flange 3 is inclined at an angle of 45, approximately, relative to the longitudinal axis XX, and beyond the latter, a pad 8 type Morse cone protrudes. Il est placé sensiblement au centre de la collerette 3, et orienté perpendiculairement à son plan, soit selon un de 1350, environ, par rapport à l'axe XX de la tige 2. It is substantially placed in the center of the flange 3, and perpendicular to its plane, according to either one of 1350, approximately, relative to the axis XX of the rod 2.

Le repère 9 à la Fig. Reference numeral 9 in Fig. la indique un aileron supéroexterne 9 placé sous la collerette 3, dans lequel sont ménagés au moins deux trous 10. Il a pour fonction d'empêcher la rotation de la tige 2 par rapport à l'humérus, et il sert également de système de fixation éventuelle du trochiter et de la coiffe. indicates the superolateral aileron 9 placed under the flange 3, wherein are provided at least two holes 10. It has the function of preventing rotation of the rod 2 with respect to the humerus, and it also serves as a fastening system potential of the greater tuberosity and the cap.

Plusieurs longueurs et diamètres de tige sont prévus en fonction des morphotypes. Several lengths and shank diameters are provided based on morphotypes. Dans une forme de réalisation satisfaisante, sept modèles différents sont réalisés à partir de trois longueurs et trois diamètres, soit In one satisfactory embodiment, seven different models are made from three lengths and three diameters or
- deux petits modèles de longueur de 120 mm avec - two small 120 mm in length models with
diamètres respectifs de 8 et 10 mm, respective diameters of 8 and 10 mm,
- trois modèles intermédiaires de longueur de 160 mm - three intermediate models length 160 mm
avec diamètres de 8, 10 et 12 mm, with diameters of 8, 10 and 12 mm,
- deux grands modèles de longueur de 200 mm avec - two large 200 mm length models
diamètres de 10 et 12 mm. diameters 10 and 12 mm.

La tête humérale 5 est par exemple en titane nitruré, pour permettre de diminuer les frottements. The humeral head 5 is, for example titanium nitride, to allow to reduce friction.

Elle a la forme générale d'un segment de sphère et présente dans sa face plane un évidement tronconique 11 disposé axialement, et formant la partie femelle d'une liaison à cône Morse pour l'assemblage avec la pièce intermédiaire 4. Comme pour la tige 2, plusieurs modèles de tête humérale sont prévus, avec des diamètres différents. It has the general shape of a spherical segment and has in its flat face a frustoconical recess 11 axially disposed and forming the female a Morse taper connection part for connection to the intermediate part 4. As for the rod 2, several humeral head models are provided with different diameters. En pratique, trois modèles sont suffisants, avec respectivement des diamètres de 34 mm, 40 mm et 46 mm, par exemple. In practice, three models are sufficient, with diameters of 34 mm respectively 40 mm and 46 mm, for example.

Conformément à l'invention, le col de la prothèse est réalisé au moyen de la pièce intermédiaire 4 entre la tige humérale 2 et la tête humérale 5, la pièce 4 étant choisie dans un jeu comprenant plusieurs modèles de longueurs différentes. According to the invention, the neck of the prosthesis is achieved by means of the intermediate part 4 between the humeral stem 2 and the humeral head 5, the piece 4 being chosen from a set comprising a plurality of different lengths models. Un tel jeu est représenté aux Figs. Such a game is shown in FIGS. 2a à 2c. 2a to 2c.

A la Fig. In Fig. 2a, la pièce intermédiaire 4a est une simple bague dont les parois interne et externe sont tronconiques pour ss'adapter respectivement sur le cône 2a, 4a intermediate part is a single ring whose inner and outer walls are tapered to ss'adapter respectively on the cone
Morse 8 de la tige 2 et dans l'évidement 11 de la tête 5. La bague 4a procure une longueur de col minimale puisqu'elle n'écarte que très peu dans la direction de celui-ci la tête humérale 5 de la collerette 3. En pratique, la bague 4a est presque intégralement prise en sandwich entre le cône 8 et la tête 5. Morse 8 of the rod 2 and in the recess 11 of the head 5. The ring 4a provides a minimum neck length since it differs very little in the direction thereof the humeral head 5 of the flange 3 . in practice, the ring 4a is almost entirely sandwiched between the cone 8 and the head 5.

Avec les pièces 4b et 4c, respectivement représentées aux Figs. With parts 4b and 4c, respectively shown in Figs. 2b et 2c, l'évidement 11 de la tête 5 et le cône 8 de la tige 2 sont décalés l'un de l'autre dans la direction YY du col, d'où la nécessité pour lesdites pièces d'une rigidité accrue par rapport à la pièce 4a. 2b and 2c, the recess 11 of the head 5 and the cone 8 of the rod 2 are offset from each other in the direction YY of the collar, hence the need for said pieces of increased rigidity by relative to the part 4a. A cet effet, leur extrémité supérieure est pleine en 41b, 41c, et autour de leur évidement de réception du cône 8, soit dans la zone 42b, 42c audessous de la partie rentrant dans la tête 5, leur section est augmentée. To this end, the upper end thereof is in full 41b, 41c, and around their receiving recess of the cone 8, be in the area 42b, 42c beneath the part falling within the head 5, their section is increased.

Les pièces 4 sont de préférence dans le même matériau que la tige 2, tel que titane, et les différents modèles d'un même jeu permettent par exemple des allongements du col par pas de 5 mm. Parts 4 are preferably of the same material as the rod 2, such as titanium, and different models of the same set enable e.g. elongations of the neck in 5 mm.

Dans une forme de réalisation satisfaisante, les pièces 4 sont au nombre de trois, et le choix entre elles s'opère en fonction de la longueur de col désirée, laquelle est déterminée en pré-opératoire avec l'aide de calques appropriées, de la radio de l'épaule défectueuse et de la radio de l'épaule contro-latérale. In one satisfactory embodiment, the parts 4 are three in number, and the choice between them is carried out depending on the desired length of neck, which is determined pre-operatively with the help of appropriate layers, the radio faulty shoulder and the radio of the contralateral shoulder.

La pièce glénoidienne 6, Fig. The glenoid piece 6, Fig. la, en matériau à faible coefficient de frottement tel que polyéthylène, a une forme générale de calotte sphérique. the, in low-friction material such as polyethylene, has a general shape of a spherical cap. Elle existe en plusieurs modèles, chacun correspondant à un modèle de tête humérale 5. Sa face concave présente une courbure horizontale de même rayon que celui de la tête humérale 5, et une courbure verticale moins prononcée pour permettre un certain roulement de celle-ci. It comes in several models, each corresponding to a humeral head model 5. The concave surface has a horizontal curvature of the same radius as that of the humeral head 5, and a vertical curvature less pronounced to permit a rolling thereof.

La partie de la pièce glénoidienne 6 destinée à être scellée dans l'omoplate est identique dans tous les modèles. The portion of the glenoid piece 6 intended to be sealed in the shoulder blade is identical in all models. Selon une caractéristique de l'invention, au lieu d'un seul moyen d'ancrage disposé centralement, elle en comporte deux, l'un supérieur et l'autre inférieur, pour diminuer les risques de descellement par rotation ou basculement. According to one characteristic of the invention, instead of a single anchorage means disposed centrally, it comprises two, one upper and the other lower, to reduce the risk of loosening by rotating or tilting. Ces moyens sont sensiblement parallèles. These means are substantially parallel. De préférence, au moins le moyen inférieur est légèrement orienté vers le bas, par exemple de 50, pour une meilleure fixation dans le pilier inférieur. Preferably, at least the lower means is slightly downwardly directed, for example 50, for a better fixing in the lower pillar.

Les moyens d'ancrage illustrés à la Fig. The anchoring means shown in Fig. la sont des plots 12 destinés à être scellés dans la glène. the pads 12 are intended to be sealed in the glenoid.

En variante, on utilise des vis, qui sont notamment préférables en cas d'arthroses excentrées avec perte importante de substance. Alternatively, screws are used, which are especially preferable in case of arthrosis eccentric with significant loss of substance. La pièce glénoidienne comporte alors une embase avec des trous de passage pour les vis, sur laquelle vient s'encliqueter la partie en polyéthylène de réception de la tête humérale. The glenoid piece then has a base with holes for the screws, on which snaps the reception polyethylene portion of the humeral head.

Le système de prothèse d'épaule selon l'invention comprend en outre un matériel ancillaire étudié en vue d'un positionnement précis des pièces humérale et glénoidienne. The shoulder prosthesis system according to the invention further comprises an ancillary material studied for a precise positioning of the humeral and glenoid parts. Concernant la pièce humérale, il comprend notamment un calque de toutes les tiges, têtes et cols prévus en tenant compte de l'agrandissement radiologique, un jeu d'alésoirs correspondant en longueur et en diamètre à chaque modèle de tige, et présentant une fente latérale pour le passage d'un ciseau servant à découper le logement de l'aileron supéro-externe 9, un guide de coupe orienté à 450 permettant une coupe précise de l'humérus pour un appui correct de la collerette 3, et un porte-prothèse permettant d'impacter la prothèse, solidement fixe à celle-ci pour éviter tout mouvement de rotation entre les deux pièces. On the humeral component, it includes a layer of all the rods, heads and collars provided taking into account the ray expansion, a set of reamers corresponding length and diameter in each rod pattern, and having a lateral slot for the passage of a chisel for cutting the housing of the upper outer fin 9, an oriented cutting guide 450 for precise cutting of the humerus for proper support of the flange 3, and a prosthesis holder allowing to impact the prosthesis securely fixed thereto to prevent rotational movement between the two parts.

Selon une autre caractéristique de l'invention, ce matériel ancillaire huméral est avantageusement complété par un système de visée externe permettant d'obtenir une rétroversion automatique de la pièce humérale qui doit être calculée à partir du plan bicondylien et qui, en pratique, reste le plus souvent très approximative par manque de moyens de pose adaptés. According to another characteristic of the invention, this humeral ancillary material is advantageously complemented by an external sighting system for obtaining an automatic retroversion of the humeral component to be calculated from the bicondylar plane and which, in practice, remains the usually very rough due to lack of suitable laying means.

Ce système de visée comprend d'une part une pièce en fer à cheval sous forme de deux modèles (droit et gauche), destinée à être serrée sur le bras au niveau de la partie inférieure de l'humérus, cette pièce étant pourvue vers l'arrière de deux tiges de repérage dans son plan, la première indiquant la position rotatoire zéro de l'humérus, et la seconde faisant avec elle un angle de 400 vers l'extérieur. The sighting system comprises firstly a horseshoe piece in two models (right and left), to be clamped on the arm at the lower part of the humerus, this piece being provided to the back of two locating rods in its plane, the first indicating the zero rotational position of the humerus, and the second forming with it an angle of 400 to the outside. D'autre part, une troisième tige devant être parallèle à ladite seconde tige lors de l'introduction de la prothèse dans l'humérus est fixée sur le porte-prothèse, perpendiculairement à l'axe longitudinal XX de la tige 2, ainsi qu'au plan (XX, On the other hand, a third rod to be parallel to said second shaft during insertion of the prosthesis in the humerus is fixed to the prosthesis holder, perpendicular to the longitudinal axis XX of the rod 2, so that to the plane (XX,
YY). YY).

Dans une version simplifiée, le système de visée externe ne comporte qu'une seule tige solidaire du porteprothèse, qu'il suffit d'orienter parallèlement à la direction de l'avant-bras, coude plié. In a simplified version, the external sighting system includes only a single rod secured to the porteprothèse, it is sufficient to orient parallel to the direction of the forearm, elbow bent. Comme ladite troisième tige du système de visée précédemment décrit, cette tige de visée est perpendiculaire à l'axe longitudinal XX de la tige d'ancrage 2. D'autre part, le plan qu'elle définit avec l'axe XX fait un angle de 1300 avec le plan (XX, YY). As said third rod of the sighting system previously described, this sighting rod is perpendicular to the longitudinal axis XX of the anchor rod 2. On the other hand, the plane which it defines with the axis XX at an angle 1300 with the plane (XX, YY).

Le matériel ancillaire glénoidien comporte, quant à lui, un guide de positionnement de la pièce glénoidienne, muni de deux trous pour pouvoir percer les logements des deux moyens d'ancrage, ce qui permet ensuite un positionnement automatique de ladite pièce. The ancillary equipment includes glenoid, meanwhile, a positioning guide of the glenoid piece, provided with two holes to be able to penetrate the housing of the two anchoring means, which then allows an automated positioning of said workpiece.

Un porte-guide vissé sur le guide soit de part et d'autre de celui-ci, soit à sa partie supérieure, permet un bon positionnement quel que soit la voie d'abord, et notamment en cas de voie d'abord supérieure. A guide holder screwed to the guide or to either side of it, or at the top, allows proper positioning regardless of the way first, and especially in case of upper track first. Par ailleurs, un porte-glène permet d'impacter la glène prothétique lors du scellement. Furthermore, a door-impact glenoid allows the prosthetic glenoid cavity during sealing.

Le système de prothèse d'épaule selon l'invention procure une très bonne précision de tous les paramètres, tant dimensionnels que de positionnement, ce qui est essentiel du point de vue fonctionnel et du point de vue de la stabilité à long terme. The shoulder prosthesis system according to the invention provides very good accuracy of all parameters, so that dimensional positioning, which is essential from a functional standpoint and from the standpoint of long-term stability. A noter que la simplicité des moyens de liaison entre les éléments formant la pièce humérale permet même, après contrôle radiologique et/ou contrôle de la tension du deltoïde et de la coiffe, d'interchanger la pièce intermédiaire en per-opératoire si ces contrôles font apparaître que le choix initial la concernant n'était pas le meilleur. Note that the simplicity of the connecting means between the elements forming the humeral component allows even after radiation monitoring and / or control the tension of the deltoid and the cap, to interchange the intermediate piece intraoperatively if such verifications shows that the initial choice for the was not the best.
