Description

La présente invention est relative à une prothèse cotyloidienne et The present invention relates to an acetabular prosthesis
plus particulièrement à un cotyle en polyéthylène susceptible d'être more particularly to an acetabular polyethylene capable of being
cimenté directement dans l'os iliaque ou impacté, c'est-à-dire enclique cemented directly into the iliac bone or affected, that is to say, snaps
té dans une pièce métallique stabilisée par des vis. side in a metal part stabilized by screws.

On sait qu'il existe à ce jour de nombreuses et différentes méthodes pour la fixation des prothèses cotyloidiennes. We know that there is to date many different methods for fixing the acetabular prosthesis.

Tout d'abord, il existe des cotyles cimentables qui sont toujours employés, mais essentiellement chez des patients jeunes et dont l'état osseux est sain. First, there are cimentables cups that are still used, but mainly in young patients whose bone health is healthy. Un tel procédé de mise en place comprend certains inconvénients dûs à la toxicité du ciment acrylique utilisé, ce qui donne Such implementation method includes some drawbacks due to the toxicity of acrylic cement used, to give
lieu à des réactions générales et à des nécroses de l'os, pouvant entraîner dans le temps le descellement de la prothèse. rise to systemic reactions and necrosis of the bone, which can lead over time the loosening of the prosthesis.

Ces inconvénients ont été résolus en associant aux prothèses consi dérées des moyens d'ancrage directs sans adjonction de ciment acrylique. These problems were solved by combining the prostheses con sidered direct anchoring means without addition of acrylic cement.

On utilise alors soit des prothèses cotyloidiennes dont la face extérieure de la calotte comporte un filetage, soit des prothèses fixées au moyen de vis. then uses either acetabular prostheses the outer face of the cap comprises a thread or prosthesis fixed by means of screws.

L'utilisation de telles prothèses entraîne certains inconvénients dûs à leur rigidité et à la méthode de mise en place dans le cotyle humain, provoquant ainsi des contraintes qui peuvent dans le temps créer des traumatismes osseux. The use of such prostheses entails some disadvantages due to their rigidity and method of implementation in the human acetabulum, causing stress that may in time create bone trauma. De même, la plupart des calottes métalliques comprennent sur la totalité de leur surface externe une rugosité permettant la réhabiLitation de l'os. Similarly, most of the metal caps comprise on their entire outer surface roughness for the rehabilitation of the bone. Ainsi, lors de nouvelles interventions chirurgicales, L'arrachage de la prothèse provoque une dégradation trop importante de ce dernier. Thus, when new surgery, Pulling the prosthesis causes excessive degradation of the latter.

C'est à ces inconvénients qu'entend plus spécialement remedier la présente invention. It is these drawbacks especially remedy the present invention.

Le cotyle artificiel en matière plastique suivant l'invention se caractérise en ce qu'il comporte des moyens permettant d'une part de cimenter Ledit cotyle directement dans l'os iliaque ou d'autre part de l'encliqueter élastiquement dans une calotte hémisphérique creuse. Artificial acetabulum plastic according to the invention is characterized in that it comprises means serving firstly to cement Said cup directly in the ilium or the other of the resiliently snap into a hollow hemispherical cap .

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre L'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer : The accompanying drawing, given by way of example, will better understand the invention, its characteristics and the benefits it can provide:

Fig. Fig. 4 est une vue semblable à celle de fig. 4 is a view similar to that of FIG. 3, mais illustrant le cotyle encliqueté dans une calotte vissée. 3, but illustrating the acetabulum snapped into a screw cap.

On a représenté en fig. There is shown in Fig. 1 une prothèse cotyloidienne 1, comportant un cotyle artificiel 2 réalisé en une matière plastique tel que le po lyéthylène à haut poids molléculaire et une calotte hémisphérique creuse 3 prévue en titane ou analogue. 1 an acetabular prosthesis 1 comprising an artificial acetabulum 2 made of a plastic material such as po lyéthylène molléculaire high weight and a hollow hemispherical cap 3 provided titanium or the like.

Dans le cotyle artificiel 2 est ménagée une cavité 2a munie d'un cône d'entrée 2b permettant le logement de la boule céphalique 4 de la prothèse fémorale 5, à la manière usuelle. In the artificial acetabular cup 2 is formed a cavity 2a provided with an inlet cone 2b to the housing of the cephalic ball 4 of the femoral prosthesis 5, in the usual manner. La face externe 2c du cotyle 2 est pourvue d'un certain nombre de rainures de retenue 2d prévues avantageusement transversales, de sorte que l'on puisse le fixer soit directement dans l'os iliaque (fig. 3), soit dans la calotte hémisphérique creuse 3 (fig. 4), comme on L'expliquera mieux plus loin. 2c external face of the cup 2 is provided with a number of retaining grooves 2d provided advantageously cross, so that one can set the either directly into the hip bone (Fig. 3) or in the hemispheric cap hollow 3 (fig. 4), as the better explained further.

La calotte hémisphérique 3 représentée en fig. The hemispherical cap 3 shown in Fig. 1 et 2 comprend sur sa paroi externe 3a et de chaque coté de son ple, d'abord une série de fentes 3b réalisées en direction de son centre et dont l'une au moins est débouchante dans un trou excentré 3c donnant une certaine souplesse à la calotte 3 afin de faciliter sa mise en place dans le cotyle humain. 1 and 2 comprises on its outer wall 3a and on each side of its ple, first a series of slots 3b made towards its center and whose at least one opens out into an eccentric hole 3c giving some flexibility to the cap 3 to facilitate its implementation in the human acetabulum.

En outre, ladite calotte 3 comprend un ensemble de trous 3d disposés sur des rayons différents permettant le passages de vis de fixation. Further, said cap 3 includes a set of 3d arranged on different radii holes for the fixing screw passages. De plus, sur la périphérie de la paroi externe 3a est établie une zone de réhabilitation de l'os Se, disposée entre le bord Sf de La calotte 3 et la première rangée de trous 3d et constituée par un moletage ou analogue. In addition, on the periphery of the outer wall 3a has established a bone rehabilitation area Se, Sf disposed between the edge of the cap 3 and the first row of holes 3d and constituted by a knurling or the like.

La partie interne 3g de La calotte 3 comporte un cordon annulaire 3k disposé en face de la zone de réhabilitation 3~, c'est-à-dire entre le bord Sf et la première rangée de trous 3 . The inner part 3g of the cap 3 comprises an annular bead 3k disposed opposite the rehabilitation zone 3 ~, that is to say between the edge Sf and the first row of holes 3. Un tel cordon 3h permet de retenir le cotyle 2 lorsque L'on a choisi de l'encliqueter dans la calotte hémisphérique creuse 3. Such cord 3h allows to retain the cup 2 when we chose to snap into the hollow hemispherical cap 3.

On a montré en fig. There is shown in Fig. 3 le cotyle artificiel 2 cimenté dans le cotyle humain 6a de l'os iliaque 6 préparé à cet effet. 3 the cemented artificial acetabular cup 2 in the human acetabulum 6a of the iliac bone 6 prepared for this purpose. On s'aperçoit que les rainures 2d disposées sur la périphérie dudit cotyle permettent l'adjonction d'un ciment acrylique afin de réaliser la retenue du cotyle artificiel 2 à l'intérieur du cotyle humain 6a. One realizes that the grooves 2d disposed on the periphery of said cup allow the addition of an acrylic cement to realize the retention of the artificial acetabular cup 2 within the human acetabulum 6a.

En fig. In Fig. 4, on a illustré la mise en place de la calotte hémisphérique creuse 3 à l'intérieur du cotyle humain 6a et dans laquelle vient s'encliqueter élastiquement le cotyle artificiel 2. 4, there is illustrated the implementation of the hollow hemispherical cap 3 within the human acetabulum 6a and in which is elastically snap the artificial acetabular cup 2.

La mise en place de la calotte hémi-sphérique creuse 3 dans le coty The establishment of the hemi-spherical cap hollow 3 in the coty
Le humain 6a s'effectue de la manière suivante : Human 6a is carried out as follows:
On fraise tout d'abord La cavité 6a suivant un diamètre légèrement inférieur à celui de la calotte 3. On introduit ensuite cette dernière dans la cavité aménagée. is firstly strawberry The cavity 6a along a diameter slightly smaller than that of the cap 3. Then we introduced the latter in the cavity formed. Cette mise en place entrain sa compression, de sorte qu'elle est maintenue à l'intérieur du cotyle humain 6a par sa simple élasticité, ce qui permet d'ajuster sa mise en place. This placement spirit its compression, so that it is maintained within the human acetabulum 6a by its simple elasticity, which allows to adjust its implementation.

Lorsque le positionnement est obtenu, on engage des vis de fixation 7 dans les différentes rangées de trous 3~, afin de rendre la calotte hémisphérique creuse 3 solidaire du cotyle humain 6a. When the positioning is obtained, is engaged fixing screws 7 in the different rows of holes 3 ~, to make the hollow hemispherical cap 3 attached to the human acetabulum 6a.

De plus, la zone de réhabilitation 3e dont la surface présente un aspect rugueux permet une repousse de l'os récepteur qui assurera la fixation secondaire biologique de l'implant. In addition, the third rehabilitation zone whose surface has a rough appearance allows regrowth of the receiver bone which will provide secondary biological fixation of the implant.

Ensuite, on vient encliqueter élastiquement le cotyle artificiel 2 à l'intérieur de la calotte hémisphérique creuse 3. L'on observe que les rainures 2d disposées sur La périphérie du cotyle 2 correspondent avec les différentes rangées de trous 3d, si bien que les têtes des vis 7 viennent s'y loger. Next, comes elastically snap the artificial acetabular cup 2 in the interior of the hollow hemispherical cap 3. It is observed that the grooves 2d disposed on the periphery of the cup 2 correspond to the different rows of holes 3d, so that the heads screws 7 are housed therein. De plus, au moins une des rainures 2d, avantageusement celle située le plus près du débouché de ta cavité 2a du cotyte 2, coopère avec Le cordon 3h de la calotte 3 afin de retenir ledit cotyle. In addition, at least one of the grooves 2d, preferably the one located closest to the outlet of thy cavity 2a of cotyte 2, cooperates with the cord 3h of the cap 3 in order to retain said acetabulum.

Cette rainure Sfl est pourvue d'un jonc métallique 8 permettant de vérifier à La radiographie la bonne mise en place du cotyle artificiel 2 à This Sfl groove is provided with a metal-ring 8 to check in Radiography proper implementation of the artificial acetabular cup 2
L'intérieur de la calotte hémisphérique creuse 3. The interior of the hollow hemispherical cap 3.

Il doit d'aiLleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the above description has been given as an example and does not limit the scope of the invention which would not depart by replacing the execution details described by any other equivalents.
