Abstract
Description
"Prothèse de hanche
La présente invention concerne une prothèse de hanche comprenant une tige destinée à être logée dans le canal fémoral, une embase ayant une surface d'appui du côté de la tige pour prendre appui sur le col fémoral et sur son autre face, un cône morse recevant la tête de prothèse."Hip prosthesis
The present invention relates to a hip prosthesis comprising a rod intended to be housed in the femoral canal, a base having a bearing surface on the side of the rod for bearing on the femoral neck and on its other face, a Morse cone receiving the prosthesis head.
Il existe différents modèles de prothèses de hanche. Ces modèles se distinguent les uns des autres par la forme de la tige, l'état de surface de la tige destinée à favoriser un accrochage osseux ou au contraire éviter cet accrochage et par la partie de l'embase recevant la tête de prothèse. There are different models of hip prostheses. These models are distinguished from each other by the shape of the stem, the surface condition of the stem intended to promote bone attachment or on the contrary avoid this attachment and by the part of the base receiving the prosthesis head.
Toutes les prothèses connues comportent une embase formée de deux surfaces parallèles, la surface tourne# vers la tige prenant appui sur le col fémoral et l'autre surface portant le cône, munie de la tête de prothèse. Les deux surfaces de l'embase sont parallèles et l'ensemble forme un bourrelet annulaire plus ou moins saillant. All known prostheses have a base formed by two parallel surfaces, the surface turns # towards the rod bearing on the femoral neck and the other surface carrying the cone, provided with the prosthesis head. The two surfaces of the base are parallel and the assembly forms a more or less protruding annular bead.
Ces prothèses fémorales constituent un compromis entre des impératifs médicaux (géométrie de l'articulation de la hanche) et des impératifs de fabrication de manière que le prix de la prothèse ne soit pas prohibitif d'autant plus que de telles prothèses ne peuvent être fabriquées en grande série et qu'il faut un assortiment de prothèses dont la longueur, l'épaisseur de la tige, la longueur entre l'embase et la tête, etc..., correspondent aux carac téristiques des différents patients. These femoral prostheses constitute a compromise between medical imperatives (geometry of the hip joint) and manufacturing imperatives so that the price of the prosthesis is not prohibitive especially since such prostheses cannot be manufactured in large series and it requires an assortment of prostheses whose length, thickness of the rod, the length between the base and the head, etc ..., correspond to the characteristics of different patients.
La présente invention a pour but de perfectionner les prothèses fémorales décrites ci-dessus en permettant un meilleur appui de l'embase contre le col fémoral sans que cela ne se traduise par une fabrication et notamment un usinage compliqué rendant le prix prohibitif. The present invention aims to improve the femoral prostheses described above by allowing better support of the base against the femoral neck without this resulting in manufacturing and in particular complicated machining making the price prohibitive.
A cet effet, l'invention concerne une prothèse de hanche du 'type ci-dessus, caractérisée en ce que la surface de l'embase portant le cône est perpendiculaire à l'axe Y-Y de l'embase, la surface de l'embase tournée vers la tige fait un angle faible ss par rapport à la surface portant le cône de sorte qu'une perpendiculaire à la surface du côté de la tige fait avec l'axe X-X de la tige un angle supérieur à 1300. To this end, the invention relates to a hip prosthesis of the 'above type, characterized in that the surface of the base bearing the cone is perpendicular to the axis YY of the base, the surface of the base turned towards the rod makes a slight angle ss with respect to the surface carrying the cone so that a perpendicular to the surface on the side of the rod makes with the axis XX of the rod an angle greater than 1300.
Une telle prothèse satisfait à la fois aux exigences médicales et à celles d'une fabrication simple. Such a prosthesis meets both medical and simple manufacturing requirements.
En effet, comme la surface de l'embase correspondant au cône morse est toujours perpendiculaire à l'axe du cône morse (axe déterminé par des impératifs physiologiques), cette partie de la prothèse se réalise de manière simple par un usinage de révolution (tour), même si, en vue en plan, la collerette formée par l'embase présente une section ellipstique ou mieux ovoidale. e. Indeed, as the surface of the base corresponding to the Morse taper is always perpendicular to the axis of the Morse taper (axis determined by physiological imperatives), this part of the prosthesis is made in a simple way by a machining of revolution (turn ), even if, in plan view, the collar formed by the base has an ellipstic or better ovoid section. e.
Par contre, comme la surface opposée de l'embase, c'est-à-dire la surface située du côté de la tige, est inclinée par rapport à la précédente, dans le sens d'une plus grande inclinaison par rapport à l'axe de la tige, cela augmente l'horizontabilité de la surface d'appui de cette collerette (prothèse de hanche) sur l'ouverture fémorale. By cons, as the opposite surface of the base, that is to say the surface located on the side of the rod, is inclined with respect to the previous one, in the direction of a greater inclination with respect to the axis of the rod, this increases the horizontality of the bearing surface of this collar (hip prosthesis) on the femoral opening.
Sur le plan mécanique, comme cette surface est moins inclinée par rapport à l'horizontale qu'une surface perpendiculaire à l'axe du cône, cela se traduit par une réduction importante de la composante horizontale du poids du patient et au contraire augmente la composante verticale qui agit dans le sens horizontal de l'os, direction dans laquelle l'os présente la meilleure résistance. Cela se traduit par un meilleur accrochage et une meilleure fiabilité de la prothèse. On the mechanical level, as this surface is less inclined with respect to the horizontal than a surface perpendicular to the axis of the cone, this results in a significant reduction in the horizontal component of the patient's weight and on the contrary increases the component vertical which acts in the horizontal direction of the bone, direction in which the bone presents the best resistance. This results in better attachment and better reliability of the prosthesis.
De manière particulièrement avantageuse, l'angle de la surface de l'embase tournée vers la tige par rapport à l'autre surface, est de 50. In a particularly advantageous manner, the angle of the surface of the base turned towards the rod relative to the other surface is 50.
La présente invention sera décrite de manière plus détaillée à l'aide des dessins annexés dans lesquels
- La figure 1 est une vue de face d'une prothèse de hanche, selon l'invention,
- Les figures 2, 3, 4 sont des #oupes respectives, selon les plans de coupe Il, III, IV de la figure 1.The present invention will be described in more detail with the aid of the accompanying drawings in which
FIG. 1 is a front view of a hip prosthesis, according to the invention,
- Figures 2, 3, 4 are respective #sections, according to the section planes II, III, IV of Figure 1.
Selon la figure 1, la prothèse de hanche se compose d'une tige 1 destinée à se loger dans le canal fémoral du patient (ce canal n'est pas représenté). Cette tige présente une section qui évolue entre son extrémité inférieure 2 arrondie et de forme sensiblement circulaire (figure 2) pour passer par une section sensiblement ellipstique (figure 3) pratiquement à mi hauteur de la tige et s'aplatir progressivement en s'agrandissant pour aboutir à la forme elliptique relativement écrasée ou mieux 6voidè écrasée (figure 4). According to Figure 1, the hip prosthesis consists of a rod 1 intended to be housed in the patient's femoral canal (this canal is not shown). This rod has a section which evolves between its rounded lower end 2 and of substantially circular shape (FIG. 2) to pass through a substantially ellipstic section (FIG. 3) practically halfway up the rod and gradually flatten out while enlarging to lead to the relatively flat or better flattened elliptical shape (figure 4).
La partie hachurée, représentée par la section de la figure 4, est la surface de jonction entre la tige 1 et l'embase 3. Cette embase 3 se compose d'une collerette 4 et d'un organe de liaison 5 portant, par exemple, un cône 6 tel qu'un cône morse, sur lequel on emmanche une rotule sphérique ou tête de prothèse (non représentée). The hatched part, represented by the section of FIG. 4, is the junction surface between the rod 1 and the base 3. This base 3 consists of a flange 4 and of a connecting member 5 carrying, for example , a cone 6 such as a morse cone, on which a spherical ball joint or prosthesis head is fitted (not shown).
La collerette 4 de l'embase 3 est délimitée par une surface 7 située du côté de la tige 1 et par une surface 5 située du côté du cône 6. The collar 4 of the base 3 is delimited by a surface 7 situated on the side of the rod 1 and by a surface 5 situated on the side of the cone 6.
L'axe X-X de la tige 1 et l'axe Y-Y de l'embase 3 forment entre eux un angle G . Cet angle $ déterminé par les caractéristiques physiologiques des individus, est égal à 1300. The axis X-X of the rod 1 and the axis Y-Y of the base 3 form an angle G between them. This angle $ determined by the physiological characteristics of the individuals, is equal to 1300.
Les surfaces 7 et 8, situées de part et d'autre de la collerette 4 de l'embase 3, font entre elles un angle ss
La surface 8 est perpendiculaire à l'axe Y-Y alors que la surface 7 est inclinée par rapport à cet axe Y-Y de manière qu'une perpendiculaire à la surface 7 fasse, avec l'axe X-X, un angle supérieur à l'angle i
En d'autres termes, la surface 7 fait avec l'axe X-X un angle supérieur à l'angle que fait la surface 8 avec cet axe X-X.The surfaces 7 and 8, located on either side of the collar 4 of the base 3, form an angle ss between them
The surface 8 is perpendicular to the axis YY while the surface 7 is inclined relative to this axis YY so that a perpendicular to the surface 7 makes, with the axis XX, an angle greater than the angle i
In other words, the surface 7 makes with the axis XX an angle greater than the angle that the surface 8 makes with this axis XX.
De cette manière, la surface 7 est plus inclinée par rapport à la direction X-X qui correspond sensiblement à la direction verticale lorsque le patient est en position debout. Ainsi, la surface 7 est moins inclinée par rapport à l'horizontale que la surface 8, c'est-à-dire que la surface 7 est moins inclinée par rapport à la direction horizontale que ne l'étaient les surfaces correspondantes des prothèses de l'art antérieur. In this way, the surface 7 is more inclined relative to the direction X-X which corresponds substantially to the vertical direction when the patient is in a standing position. Thus, the surface 7 is less inclined relative to the horizontal than the surface 8, that is to say that the surface 7 is less inclined relative to the horizontal direction than were the corresponding surfaces of the prostheses of prior art.
Cela se traduit par une meilleure répartition des composantes du poids dans la direction horizontale et dans la direction verticale. En effet, en rapprochant la surface 7 de la direction horizontale, on augmente la composante verticale du poids, ce qui se traduit par de meilleures conditions statiques et dynamiques en position debout et en position de marche pour le patient ces meilleures conditions se répercutent sur une plus grande fiabilité de la liaison prothèse-fémur. This results in a better distribution of the weight components in the horizontal direction and in the vertical direction. Indeed, by bringing the surface 7 closer to the horizontal direction, the vertical component of the weight is increased, which results in better static and dynamic conditions in the standing position and in the walking position for the patient, these better conditions have an impact on greater reliability of the prosthesis-femur link.
