Abstract

The stem has, on its large faces, starting from the base of the prosthetic neck (2) receiving a femoral head, a series of grooves parallel to the axis (x - x') of the rod, one (5a) of which, situated substantially on the said axis, is larger than the grooves situated on either side of the said axial groove.

Description

Tige fémorale pour articulation de la hanche. Femoral stem for hip joint.

L'objet de l'invention se rattache au secteur technique des prothèses de hanche. The object of the invention is related to the technical sector of hip prostheses.

Suivant l'invention, on a voulu réaliser une tige fémorale parfaitement adaptée aux différentes morphologies de fémurs, pouvant être implantée efficacement avec ou sans ciment et assurant une stabilité et un ancrage satisfaisants dans le temps. According to the invention, it has been desired to provide a femoral stem that is perfectly adapted to the different morphologies of femurs, that can be implanted effectively with or without cement and that ensures satisfactory stability and anchorage over time.

Pour cela et selon une première caractéristique, la tige fémorale qui est du type autobloquante dans le plan sagittal et dans le plan frontal par la géométrie particulière de sa partie proximale, présente sur ses grandes faces à partir de la base du col prothétique recevant une tête fémorale, une série de rainures parallèles à l'axe de la tige dont l'une, située sensiblement sur le dit axe, est de dimensions plus importantes que les rainures situées de part et d'autre de la dite rainure axiale. For this and according to a first feature, the femoral stem which is of the self-locking type in the sagittal plane and in the frontal plane by the particular geometry of its proximal portion, has on its large faces from the base of the prosthetic neck receiving a head femoral, a series of grooves parallel to the axis of the rod, one of which, situated substantially on the said axis, is of greater dimensions than the grooves located on either side of the said axial groove.

Selon une autre caractéristique, la rainure axiale s'étend sensiblement sur toute la hauteur de la tige fémorale, tandis que les rainures latérales sont limitées à la partie proximale de la tige, avec des hauteurs différentes. According to another feature, the axial groove extends substantially over the entire height of the femoral stem, while the lateral grooves are limited to the proximal portion of the stem, with different heights.

Selon une autre caractéristique, la rainure axiale est plus longue et plus profonde que les rainures laterales. According to another characteristic, the axial groove is longer and deeper than the lateral grooves.

Une autre caractéristique se trouve dans le fait que pour une implantation de la tige fémorale sans ciment dans le canal médullaire, celle-ci reçoit au moins dans sa zone mêtaphysaire préalablement rendue micro-poreuse, une couche dthydroxyapatite par projection à la torche plasma. Another feature is that for implantation of the femoral stem without cement in the medullary canal, the latter receives at least in its metaphyseal zone previously made microporous, a layer of hydroxyapatite by plasma blasting.

Ces caractéristiques et d'autres encore, ressortiront de la description qui suit. These and other features will be apparent from the following description.

Pour fixer l'objet de l'invention sans toutefois le limiter dans le dessin annexe :
La figure 1 est une vue de face de la tige fémorale selon l'invention,
La figure 2 est une vue en coupe considérée suivant la ligne 2 - 2 de la figure 1.To fix the object of the invention without however limiting it in the attached drawing:
FIG. 1 is a front view of the femoral stem according to the invention,
FIG. 2 is a sectional view taken along the line 2--2 of FIG. 1.

La figure 3 est une vue partielle en coupe à grande échéelle considérée suivant la ligne 3 - 3 de la figure 1.  FIG. 3 is a partial sectional view with a large time-line taken along line 3 - 3 of FIG. 1.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous une forme non limitative de réalisation illustrée aux figures du dessin. In order to make more concrete the object of the invention, it is now described in a non-limiting embodiment illustrated in the figures of the drawing.

La tige fémorale (1) illustrée est du type autobloquante en ce sens qu'un remplissage metaphysaire optimal est obtenu par une section ovoide de la partie proximale de la tige dans le plan sagittal, associée a un contact cortical à rainures multiples dans le plan frontal. The femoral stem (1) illustrated is of the self-locking type in that an optimal metaphyseal filling is obtained by an ovoid section of the proximal portion of the stem in the sagittal plane, associated with a multi-groove cortical contact in the frontal plane. .

Dans le détail, en dessous du col prothétique (2 > recevant de manière connue une tête fémorale, les deux grandes faces (3 - 4 > , présentent une série de rainures < 5? parallèles à l'axe (x - x' > de la tige et de dimensions différentes. In detail, below the prosthetic neck (2> receiving in known manner a femoral head, the two large faces (3 - 4>, have a series of grooves <5? Parallel to the axis (x - x '> of the stem and of different dimensions.

Une rainure axiale (5 a > , située sur l'axe x s'étend sensiblement sur toute la hauteur de la tige fémorale, tandis que des rainures latérales (5 b, 5 c, 5 d,5 e) sont limitées à la partie proximale de la tige avec des hauteurs différentes en correspondance avec le profil de la tige. An axial groove (5 a>, located on the x axis extends substantially over the entire height of the femoral stem, while lateral grooves (5 b, 5 c, 5 d, 5 e) are limited to the part proximal of the stem with different heights corresponding to the profile of the stem.

La rainure axiale t5 a) a une largeur et une profondeur plus importantes que les rainures latérales qui peuvent être de même largeur et profondeur ou diftérentes.  The axial groove t5 a) has a greater width and depth than the lateral grooves which can be of the same width and depth or difterent.

Pour implanter ces tiges dans le canal médullaire du fémur sans adjonction de ciment, il est prévu de revêtir la zone métaphysaire au moins d'une couche (C > dlhydroxyapatite par projection à la torche plasma. Pour celai au préalable, on rend par tous moyens connus la dite zone micro-poreuse. In order to implant these stems in the medullary canal of the femur without the addition of cement, it is planned to coat the metaphyseal zone with at least one layer (C> of hydroxyapatite by plasma blasting. known as said microporous zone.

Bien entendu, pour satisfaire à tous les besoins en fonction de la morphologie du sujet, on réalise une gamme de tiges fémorales a progression tridimensionnelle comprenant des tiges latéralisées à col court destinées aux cas de dysplasies et des tiges non lateralisées à col moyen. Of course, in order to satisfy all the needs according to the morphology of the subject, a range of three-dimensional progression femoral stems comprising short-necked lateralized stems intended for the cases of dysplasias and non-lateralised stems with a medium neck are produced.

D'autre part, on utilise des rapes formant tiges d'essai spécialement étudiées afin de réaliser l'empreinte exacte des tiges définitives et de conserver ainsi de l'os spongieux dans les rainures de la tige. On the other hand, rapes forming test rods specially designed to perform the exact imprint of the final stems and thus to preserve spongy bone in the grooves of the stem.

La bici-activité de l'hydroxyapatite accélère l'ostéogénèse et l'ancrage de l'os néo-formé s'opère au niveau du materiau (titane) micro-poreux. The bici-activity of hydroxyapatite accelerates osteogenesis and the anchorage of the neo-formed bone takes place at the level of the material (titanium) micro-porous.

De même, la différenciation des dimensions des rainures, en particulier les dimensions plus importantes de la rainure axiale, assurent une meilleure stabilité et un meilleur ancrage.  Similarly, the differentiation of the dimensions of the grooves, in particular the larger dimensions of the axial groove, provide better stability and better anchoring.
