Abstract

The humeral shank for a shoulder prosthesis has a reinsertion finn (1a) on the outside of its proximal end, connected to the head by lengthwise and transverse sections which ensure the partial integration of the fin into the general volume defined by the body of the shank (1). The lengthwise connecting section is formed by grooves (1c) on either side of the fin, linking progressively with the body of the shank, while the transverse section is formed by cut-away surfaces designed to reduce the cross-section of the body at the level of the fin. The proximal end of the shank is also equipped with a thrust collar (1g) which is oval in shape, and has a hole (1f) pierced through it. ADVANTAGE - More reliable retention of bone fragments from fractured shoulder.

Description

Tige humérale pour prothèse d'épaule.  Humeral stem for shoulder prosthesis.

On distingue essentiellement, deux grands types de tiges humérales, en fonction de leur mode d'ancrage dans l'humérus, avec ou sans ciment. There are essentially two main types of humeral stems, depending on how they are anchored in the humerus, with or without cement.

Ces tiges sont appliquées, soit pour des traitements dégénératifs, soit pour des traitements traumatologiques. Par contre, aucune prothèse ne répond à ces deux indications. These rods are applied, either for degenerative treatments, or for trauma treatments. However, no prosthesis meets these two indications.

Un des problèmes que se propose de résoudre l'invention, est de créer une prothèse humérale, qui, notamment au niveau de sa tige, réponde aux indications d'un traitement dégénératif et d'un traitement traumatologique. One of the problems which the invention proposes to solve is to create a humeral prosthesis, which, in particular at the level of its stem, responds to the indications of degenerative treatment and trauma treatment.

Un autre problème que se propose de résoudre l'invention est d'équiper la tige d'un système permettant le positionnement et le maintien de fragments osseux, notamment dans le cas où il est nécessaire de réunir les morceaux d'une épaule éclatée. Another problem which the invention proposes to solve is to equip the rod with a system allowing the positioning and the maintenance of bone fragments, in particular in the case where it is necessary to join the pieces of an exploded shoulder.

On connaît des tiges fémorales présentant en débordement au niveau de leur partie proximale, une ailette de réinsertion équipée de trous pour le rapprochement et le maintien des fragments osseux, en combinaison avec des fils de suture. Toutefois, il apparait que l'ailette déborde totalement du profil de la tige humérale, en créant ainsi une saillie qui risque de traverser la gouttière de l'humérus. There are known femoral stems having an overflow at their proximal part, a reinsertion wing equipped with holes for bringing together and maintaining the bone fragments, in combination with suture threads. However, it appears that the fin completely overflows from the profile of the humeral rod, thereby creating a projection which risks crossing the gutter of the humerus.

L'invention s'est fixée pour but de remédier à ces inconvénients, d'une manière simple, sûre et efficace. The object of the invention is to remedy these drawbacks in a simple, safe and effective manner.

Le problème que se propose de résoudre l'invention est d'éviter tout problème de fractures per-opératoires, compte-tenu de la présence de l'ailette, tout en conservant ses trous, pour le rapprochement des fragments osseux des plans postérieur et antérieur. The problem which the invention proposes to solve is to avoid any problem of intraoperative fractures, taking into account the presence of the fin, while retaining its holes, for bringing together the bone fragments of the posterior and anterior planes. .

Un tel problème est résolu en ce que l'ailette est raccordée au corps de la tige par un profil longitudinal et transversal aptes à assurer l'intégration partielle de ladite ailette dans le volume général défini par la section du corps de la tige. Such a problem is solved in that the fin is connected to the body of the rod by a longitudinal and transverse profile capable of ensuring the partial integration of said fin in the general volume defined by the section of the body of the rod.

II apparait que cette géométrie externe proximale de la tige humérale permet de mettre en contact les fragments osseux, les uns par rapport aux autres, tout en assurant une repousse osseuse la plus rapide possible. It appears that this proximal external geometry of the humeral rod makes it possible to bring the bone fragments into contact, one with respect to the other, while ensuring bone regrowth as quickly as possible.

Avantageusement, le profil longitudinal est constitué par des rainures formées de part et d'autre de l'ailette et s'étendant d'une manière progressivement décroissante avec le corps de la tige. Le profil transversal est constitué par des pans coupés déterminés de manière à diminuer la section du corps de la tige au niveau de l'ailette. Advantageously, the longitudinal profile is formed by grooves formed on either side of the fin and extending in a progressively decreasing manner with the body of the rod. The transverse profile consists of cut sides determined so as to reduce the cross-section of the body of the rod at the level of the fin.

Suivant une autre caractéristique, la partie supérieure de chacune des rainures est raccordée au niveau de la partie proximale par un profil étagé. According to another characteristic, the upper part of each of the grooves is connected at the level of the proximal part by a stepped profile.

L'extrémité supérieure de l'ailette et du profil étagé constituent un pan incliné dont les bords sont coupés.The upper end of the fin and of the stepped profile constitute an inclined section whose edges are cut.

Pour résoudre le problème posé d'assurer une parfaite stabilité de la tige après impaction dans le canal médullaire, cette dernière présente à sa partie proximale, une collerette d'appui de forme ovoïde. To resolve the problem posed of ensuring perfect stability of the rod after impaction in the medullary canal, the latter has at its proximal part, a support flange of ovoid shape.

Pour résoudre le problème posé de faire une synthèse entre le compartiment interne et externe, la tige est percée transversalement, de part en part, au niveau de sa partie proximale, notamment dans la partie médiane de la méthaphyse. Ce trou permet le passage d'un passe fils. To solve the problem posed of making a synthesis between the internal and external compartment, the rod is pierced transversely, right through, at its proximal part, in particular in the middle part of the methaphyse. This hole allows the passage of a grommet.

L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels:
La figure 1 est une vue partielle en perspective de la partie proximale de la tige humérale selon l'invention.The invention is set out below in more detail using the appended drawings, in which:
Figure 1 is a partial perspective view of the proximal part of the humeral rod according to the invention.

La figure 2 est une vue de face de la tige selon l'invention. Figure 2 is a front view of the rod according to the invention.

Les figures 3 et 4 sont des vues de côté correspondant à la figure 2. Figures 3 and 4 are side views corresponding to Figure 2.

La figure 5 est une vue partielle et en coupe, de la partie proximale de la tige humérale. Figure 5 is a partial sectional view of the proximal part of the humeral rod.

La figure 6 est une vue en coupe transversale considérée selon la ligne 6.6. de la figure 5. Figure 6 is a cross-sectional view taken along line 6.6. in Figure 5.

La figure 7 montre l'impaction de la tige humérale. Figure 7 shows the impaction of the humeral stem.

La tige humérale désignée dans son ensemble par (1), présente d'une manière connue, une ailette de réinsertion (la). Cette ailette présente une série de trous (1b) pour le positionnement et le maintien des fragments osseux. The humeral rod generally designated by (1), has in a known manner, a reinsertion wing (la). This fin has a series of holes (1b) for positioning and maintaining the bone fragments.

Selon l'invention, L'ailette (1 a) est raccordée au corps de la tige (1), par des profils longitudinal et transversal, aptes à assurer l'intégration partielle de ladite ailette dans le volume général défini par la section du corps de la tige.  According to the invention, the fin (1a) is connected to the body of the rod (1), by longitudinal and transverse profiles, capable of ensuring the partial integration of said fin in the general volume defined by the section of the body. of the stem.

Comme le montrent notamment les figures 1 et 4, le profil longitudinal est constitué par des rainures (tic) et (nid) formées de part et d'autre de l'ailette (la). Ces rainures (1c) et (1d), se raccordent de manière progressivement décroissante avec le corps de la tige. La partie supérieure de chacune des rainures (tic) et (nid) est raccordée au niveau de la partie proximale par un profil étagé (ici) (1d1). L'extrémité supérieure du profil étagé (ici) (ide) et l'extrémité supérieure de l'ailette (la) constituent un pan incliné (1e), dont les bords sont biseautés. As shown in particular in Figures 1 and 4, the longitudinal profile is constituted by grooves (tic) and (nest) formed on either side of the fin (la). These grooves (1c) and (1d), connect progressively decreasing with the body of the rod. The upper part of each of the grooves (tic) and (nest) is connected at the proximal part by a stepped profile (here) (1d1). The upper end of the stepped profile (here) (ide) and the upper end of the fin (la) constitute an inclined face (1e), the edges of which are bevelled.

Suivant une autre caractéristique, la partie proximale de la tige (1) présente, au niveau de sa métaphyse, un trou transversal (If), pour permettre te positionnement et le maintien des fragments osseux, en combinaison avec les trous (lob) de l'ailette (la). La partie proximale de la tige présente une colerette d'appui (1g), de forme ovoïde. According to another characteristic, the proximal part of the rod (1) has, at its metaphysis, a transverse hole (If), to allow the positioning and the maintenance of the bone fragments, in combination with the holes (lob) of the 'fin (the). The proximal part of the stem has a support flange (1g), of ovoid shape.

Bien évidemment, comme le montre notament la figure 5, la partie supérieure de la tige, présente tout agencement (1h) permettant la fixation d'une tête humérale (2). Obviously, as shown in Figure 5, the upper part of the rod has any arrangement (1h) allowing the attachment of a humeral head (2).

Les avantages ressortent bien de la description, en particulier on souligne et-on rappelle l'intégration de l'ailette évitant tout problème de fracture per-opératoire, tout en conservant les trous pour le rapprochement des fragments osseux des plans postérieur et antérieur.  The advantages emerge clearly from the description, in particular it underlines and-one recalls the integration of the fin avoiding any problem of intraoperative fracture, while retaining the holes for bringing together the bone fragments of the posterior and anterior planes.
