Abstract

The prosthesis consists of a shank (1) which bulges at its proximal end, which is connected by a base (2) and a neck (3) to a cone (4). The proximal end of the shank has a series of surface grooves (20A-20D), all but one of which has a rounded closed end before it meets the base. The shank comprises diaphysial (10) and epiphysial (13) sections, with the grooves only in the latter; each groove's rounded end is an a quarter olive shape, about 4mm across and 5mm long by 1mm deep.

Description

"Tige fémorale à rainures pour prothèse de la hanche"
La présente invention concerne une tige fémorale à rainures pour prothèse de la hanche."Femoral stem with grooves for hip prosthesis"
The present invention relates to a grooved femoral stem for hip prosthesis.

D'une manière générale, une telle tige comporte un fût, destiné à être engagé dans le canal médullaire d'un fémur, tulipé en partie proximale, raccordé par un socle à un col se terminant par un tronc de cône destiné à coopérer avec une tête de fémur. In general, such a rod comprises a barrel, intended to be engaged in the medullary canal of a femur, tulipated in the proximal part, connected by a base to a neck ending in a truncated cone intended to cooperate with a femur head.

Afin d'accroître l'ancrage, notamment antirotatoire, du fût dans le spongieux du fémur et/ou dans un ciment polymère, on a proposé d'aménager sur ce fût des rainures unidirectionnelles et parallèles entres elles selon la direction générale de ce dernier, de manière à y créer un nacrorelief.  In order to increase the anchoring, in particular anti-rotation, of the barrel in the cancellous part of the femur and / or in a polymer cement, it has been proposed to arrange on this barrel unidirectional grooves parallel to each other in the general direction of the latter, so as to create a nacrorelief there.

On a constaté qu'avec des rainures arrivant débouchantes sur le socle, le spongieux et/ou le ciment a tendance à être évacué vers l'extérieur et l'ancrage du fût est mal réalisé. It has been found that with grooves arriving emerging on the base, the cancellous and / or the cement tends to be evacuated towards the outside and the anchoring of the barrel is poorly carried out.

On a constaté également qu'avec des rainures arrivant non débouchantes le spongieux et/ou le ciment était à l'inverse soumis & de trop fortes pressions. It has also been found that with non-opening arriving grooves the cancellous and / or the cement was conversely subjected to too strong pressures.

La présente invention a pour but d'améliorer l'ancrage, notamment antirotatoire, de ce type de tige fémorale. The present invention aims to improve the anchoring, in particular anti-rotation, of this type of femoral stem.

Elle propose une tige fémorale pour prothèse de la hanche comportant un fût qui est tulipé en partie proximale, destiné à être engagé dans le canal médullaire d'un fémur et sur lequel est raccordé par un socle un col se terminant par un tronc de cône destiné à coopérer avec une tête de fémur, des rainures étant ménagées longitudinalement sur ledit fût, caractérisée en ce que toutes les rainures arrivent non débouchantes sur ledit socle exceptée la rainure la plus interne située à la base du col qui arrive débouchante sur ledit socle. It proposes a femoral stem for hip prosthesis comprising a barrel which is tulipated in the proximal part, intended to be engaged in the medullary canal of a femur and on which is connected by a base a neck ending in a truncated cone intended to cooperate with a femur head, grooves being formed longitudinally on said barrel, characterized in that all the grooves arrive non-emerging on said base except the innermost groove located at the base of the neck which arrives through said base.

Grâce à cette conception, on obtient un bon ancrage du fût dans le site prothétique tout en évitant de mettre le ciment ou le spongieux sous trop forte pression. Thanks to this design, a good anchoring of the barrel is obtained in the prosthetic site while avoiding putting the cement or the cancellous bone under too strong pressure.

On combine ainsi les effets d'ancrage des rainures non débouchantes et les effets d'évacuation des rainures débouchantes. This combines the anchoring effects of the non-opening grooves and the evacuation effects of the opening grooves.

Selon un mode de réalisation préféré, l'extrémité des rainures non débouchantes qui se trouve au voisinage du socle présente une forme dite "en quart d'olive", correspondant à une olive coupée en quatre une fois dans le sens de sa longueur et une fois dans le sens de sa largeur. Cette forme permet une compression convenable du ciment et/ou du spongieux. According to a preferred embodiment, the end of the non-opening grooves which is in the vicinity of the base has a shape called "quarter olive", corresponding to an olive cut in four once in the direction of its length and a times across its width. This form allows proper compression of the cement and / or the sponge.

La présente invention sera mieux comprise et d'autres avantages apparaîtront à la lumière de la description qui va suivre d'un exemple de réalisation faite en référence aux dessins annexés sur lesquels
- la figure 1 est une vue de côté d'une tige fémorale selon un exemple de réalisation de l'invention
- la figure 2 est une vue arrière de la tige fémorale de la figure 1 selon la flèche II ;
- la figure 3 est une vue en coupe selon la ligne III
III de la figure 1
- la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 1 illustrant ; et
- la figure 5 est une vue selon la flèche V de la figure 4.The present invention will be better understood and other advantages will appear in the light of the following description of an embodiment given with reference to the accompanying drawings in which
- Figure 1 is a side view of a femoral stem according to an exemplary embodiment of the invention
- Figure 2 is a rear view of the femoral stem of Figure 1 according to arrow II;
- Figure 3 is a sectional view along line III
III of figure 1
- Figure 4 is a sectional view along line IV-IV of Figure 1 illustrating; and
- Figure 5 is a view along arrow V in Figure 4.

Selon l'exemple de réalisation choisi et représenté sur les figures, la tige fémorale presente une forme classique et connue en soi avec un fût 1 destiné à être engagé dans le canal médullaire d'un fémur surmonté d'un socle 2 avec un col 3 se terminant par un tronc de cône 4 destiné à coopérer avec une tête de fémur. According to the embodiment chosen and shown in the figures, the femoral stem has a conventional shape and known per se with a shaft 1 intended to be engaged in the medullary canal of a femur surmounted by a base 2 with a neck 3 ending with a truncated cone 4 intended to cooperate with a femur head.

Le fût 1 comprend une lame diaphysaire 10 à axe rectiligne 11 qui s'effile vers une pointe terminale 12 et un tronçon épiphysaire 13 qui s'élargit depuis la lame diaphysaire 10 jusqu'au socle 2. La direction générale 15 du col 3 forme un angle avec l'axe 11 de la lame diaphysaire 10 correspondant à l'angle cervico-diaphysaire naturel du sujet. Le tronçon épiphysaire 13 présente une section de forme ovoïde avec deux faces 13A et 13B globalement planes réunies par des bords arrondis 16 et 17. Selon cet exemple de réalisation sur chaque face 13A et 13B du tronçon épiphysaire 12 sont ménagées quatre rainures, 20A, 20B, 20C et 20D. Elles s'étendent selon la direction générale de l'axe rectiligne 11 de la lame diaphysaire 10, parallèlement entre elles. La rainure 20D la plus interne située à la base du col 3 arrive débouchante sur le socle 2 (comme on le voit mieux sur la figure 3), tandis que les autres rainures 20A, 20B et 20C arrivent non débouchantes sur le socle 2. Les rainures non-débouchantes les plus externes 20A sont situées à l'amorce du bord arrondi 16 comme cela est visible sur la figure 2. The barrel 1 comprises a diaphyseal blade 10 with a rectilinear axis 11 which tapers towards an end point 12 and an epiphyseal section 13 which widens from the diaphyseal blade 10 to the base 2. The general direction 15 of the neck 3 forms a angle with the axis 11 of the diaphyseal blade 10 corresponding to the subject's natural cervico-diaphyseal angle. The epiphyseal section 13 has an ovoid-shaped section with two generally planar faces 13A and 13B joined by rounded edges 16 and 17. According to this embodiment on each face 13A and 13B of the epiphyseal section 12 are formed four grooves, 20A, 20B , 20C and 20D. They extend in the general direction of the rectilinear axis 11 of the diaphyseal blade 10, parallel to each other. The innermost groove 20D located at the base of the neck 3 arrives through the base 2 (as can be seen more clearly in FIG. 3), while the other grooves 20A, 20B and 20C arrive non-emerging on the base 2. The outermost non-emerging grooves 20A are located at the start of the rounded edge 16 as can be seen in FIG. 2.

L'extrémité des rainures non débouchantes 20A, 20B et 20C, au voisinage du socle 2 présente une forme dite "quart d'olive" que l'on peut définir par les paramètres a largeur de l'olive, b demi-hauteur de olive et c demi-profondeur de l'olive. La valeur de a est environ 5 mm, la valeur de b environ 4 mm et la valeur de c environ 1 mm, selon la profondeur de rainure désirée. L'autre extrémité de l'ensemble des rainures 20A - 20D s'amenuise de manière classique en pointe. The end of the non-emerging grooves 20A, 20B and 20C, in the vicinity of the base 2 has a shape called "quarter olive" which can be defined by the parameters a width of the olive, b half height of olive and c half depth of the olive. The value of a is approximately 5 mm, the value of b approximately 4 mm and the value of c approximately 1 mm, depending on the desired groove depth. The other end of the set of grooves 20A - 20D tapers in a conventional manner to a point.

Il va de soi que des variantes de réalisations sont possibles notamment concernant la forme du fût de la tige ou le nombre de rainures qui est bien entendu proportionnel à la largeur des faces 13A, 13B.  It goes without saying that variant embodiments are possible, in particular concerning the shape of the barrel of the rod or the number of grooves which is of course proportional to the width of the faces 13A, 13B.
