Description

PLAQUE D'OSTEOTOMIE TIBIALE D'ADDITION.TIBIAL OSTEOTOMY PLATE OF ADDITION.

La présente invention concerne une plaque d'ostéotomie tibiale d'addition.  The present invention relates to a tibial osteotomy plate of addition.

L'ostéotomie tibiale est l'opération consistant à régler la hauteur du plateau tibial par sectionnement de la masse osseuse sous celui-ci, et intrusion d'un coin de réglage.  The tibial osteotomy is the operation of adjusting the height of the tibial plateau by severing the bone mass under it, and intrusion of a wedge.

L'utilisation d'une plaque d'ostéotomie d'addition s'impose pour réunir et stabiliser la masse osseuse de part et d'autre du coin.  The use of an addition osteotomy plate is necessary to bring together and stabilize the bone mass on both sides of the corner.

Différents types de plaques sont connues, par exemple de forme rectangle, et généralement surdimensionnée par rapport au besoin, ce qui oblige les praticiens à effectuer des incisions d'ouverture importantes au niveau de la jambe.  Different types of plates are known, for example of rectangle shape, and generally oversized compared to the need, which requires practitioners to make significant opening incisions in the leg.

La plaque doit dans chaque cas, pour remplir sa fonction, déborder largement de chaque côté de l'entaille osseuse et du coin qui la comble.  The plate must in each case, to fulfill its function, overflow widely on each side of the bone notch and the corner that fills it.

L'un des buts essentiels de l'invention est de remplir cette fonction en assurant une liaison efficace des parties reliées, tout en permettant de réaliser une incision de dimension la plus réduite possible.  One of the essential aims of the invention is to fulfill this function by ensuring an effective connection of the connected parts, while allowing to make an incision as small as possible.

A cet effet, la plaque d'ostéotomie tibiale d'addition, selon l'invention, se caractérise en ce qu'elle comprend deux branches sensiblement horizontales, dont une supérieure et une inférieure réunies par une traverse, les branches étant dotées de perçages de fixation à l'os.  For this purpose, the tibial addition osteotomy plate, according to the invention, is characterized in that it comprises two substantially horizontal branches, of which one upper and one lower joined by a cross-member, the branches being provided with drill holes. fixation to the bone.

Suivant une autre disposition, la plaque d'ostéotomie tibiale d'addition selon l'invention se caractérise en ce que chacune des branches est pourvue de trois perçages.  According to another arrangement, the tibial osteotomy plate according to the invention is characterized in that each of the branches is provided with three bores.

Suivant une autre disposition, la plaque d'ostéotomie tibiale selon l'invention se caractérise en ce que la branche supérieure est dotée d'un perçage circulaire à chacune de ses extrémités et d'un perçage médian oblong.  According to another arrangement, the tibial osteotomy plate according to the invention is characterized in that the upper branch is provided with a circular bore at each of its ends and a median oblong hole.

Suivant une autre disposition, la plaque d'ostéotomie tibiale selon l'invention, se caractérise en ce que le perçage oblong médian est orienté transversalement à la plaque.  According to another arrangement, the tibial osteotomy plate according to the invention is characterized in that the median oblong hole is oriented transversely to the plate.

Suivant une autre disposition, la plaque d'ostéotomie tibiale se caractérise en ce que le perçage médian est de longueur supérieure à celui du diamètre des perçages d'extrémité, et est incliné en biais par rapport à l'axe de la branche.  According to another arrangement, the tibial osteotomy plate is characterized in that the medial bore is of greater length than the diameter of the end bores, and is inclined at an angle to the axis of the branch.

Suivant une autre disposition, la plaque d'ostéotomie tibiale se caractérise en ce que la branche inférieure est dotée de trois perçages, un circulaire à chaque extrémité et un oblong médian.  According to another arrangement, the tibial osteotomy plate is characterized in that the lower branch is provided with three bores, a circular at each end and a median oblong.

D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description d'une forme préférentielle de l'invention illustrée par les dessins joints dans lesquels: - La figure 1 est une vue montrant une ostéotomie tibiale avec utilisation de la plaque selon l'invention.  Other advantages and characteristics of the invention will appear on reading the description of a preferred form of the invention illustrated by the accompanying drawings in which: FIG. 1 is a view showing a tibial osteotomy using the plate according to the invention.

- La figure 2 est une vue en plan, à échelle agrandie par rapport à l'échelle originale de la plaque selon l'invention.  - Figure 2 is a plan view on an enlarged scale with respect to the original scale of the plate according to the invention.

- La figure 3 est une vue en coupe transversale de la plaquette, la coupe étant réalisée au niveau de la branche supérieure montrant le pliage de la plaquette.  - Figure 3 is a cross-sectional view of the wafer, the section being formed at the upper branch showing the folding of the wafer.

L'opération d'ostéotomie tibiale, comme illustrée en figure 1, consiste à régler la position du plateau tibial 1 en réalisant une découpe sous celui-ci, et en y introduisant un coin de réglage 2 en matériau biocompatible, par exemple en céramique. II est utilisé une plaque 3, de chaque coté du tibia pour réunir la masse osseuse de part et d'autre du coin de réglage.  The tibial osteotomy operation, as illustrated in FIG. 1, consists in adjusting the position of the tibial plateau 1 by cutting under it, and by introducing an adjustment wedge 2 of biocompatible material, for example ceramic. A plate 3 is used on each side of the tibia to join the bone mass on either side of the adjustment wedge.

La figure 2 illustre la plaque d'ostéotomie tibiale d'addition selon l'invention qui comprend deux branches sensiblement horizontales, dont une supérieure 4 et une inférieure 5 réunies par une traverse 6.  FIG. 2 illustrates the tibial osteotomy plate according to the invention which comprises two substantially horizontal branches, of which an upper 4 and a lower 5 joined by a crossbar 6.

Chacune des branches est pourvue de trois perçages. La branche supérieure 4 est dotée d'un perçage circulaire de fixation dans l'os, par vis à chacune de ses extrémités, soit deux perçages de fixation 7-8 et d'un perçage médian oblong 9.  Each of the branches is provided with three holes. The upper branch 4 is provided with a circular drilling for fixation in the bone, with screws at each of its ends, namely two fixing holes 7-8 and an oblong medial piercing 9.

Le perçage médian oblong 9 est un perçage de réglage, par lequel sera vissé une vis provisoire en préalable au vissage définitif, qui permet de bouger la plaque pour régler sa position.  The median oblong hole 9 is a setting bore, which will be screwed a temporary screw before the final screwing, which moves the plate to adjust its position.

Le perçage médian oblong 9 est orienté transversalement à la branche 4 et est incliné en biais par rapport à l'axe longitudinal AA de la branche. Sa longueur est supérieure au diamètre de perçages 7 et 8.  The median oblong bore 9 is oriented transversely to the branch 4 and is inclined at an angle to the longitudinal axis AA of the branch. Its length is greater than the diameter of holes 7 and 8.

Ces dispositions permettent d'obtenir de grandes possibilités de réglage de la position de la plaque par rotation de celle-ci autour de la vis provisoire et/ou par un déplacement de haut en bas et inversement de la plaque par rapport à la vis provisoire.  These arrangements make it possible to obtain great possibilities of adjusting the position of the plate by rotating it around the temporary screw and / or by moving up and down and vice versa the plate relative to the temporary screw.

La branche inférieure 5 est dotée de trois perçages circulaires dont un à chacune des ses extrémités 10 / 11 et un oblong et médian.  The lower branch 5 is provided with three circular holes, one at each of its ends 10/11 and an oblong and median.

Les trois perçages sont sur le même axe, défini par le centre des perçages d'extrémités. Les branches supérieure 4 et inférieure 5 sont décalées angulairement.  The three holes are on the same axis, defined by the center of the end holes. The upper 4 and lower 5 branches are angularly offset.

L'axe AA passant par le centre des perçages 7 8 de la branche 4 est horizontal.  The axis AA passing through the center of the holes 7 8 of the branch 4 is horizontal.

L'axe BB passant par le centre des perçages 10 11 de la branche inférieure 5 est incliné vers l'extérieur pour donner de l'ouverture, qui permet une meilleure adaptation à la forme du coin de réglage et à la nouvelle position de la tête fémorale.  The axis BB passing through the center of the bores 10 11 of the lower branch 5 is inclined outwards to give the opening, which allows a better adaptation to the shape of the adjustment wedge and the new position of the head femoral.

Avantageusement, comme représenté vue en coupe en figure 3, la 20 plaquette est pliée suivant un axe CC médian transversal aux deux branches 4 5.  Advantageously, as shown in sectional view in FIG. 3, the wafer is folded along a median CC axis transverse to the two branches 45.

Cette disposition permet de donner une angulation aux perçages et donc de donner une inclinaison vers l'intérieur aux vis de fixation définitives.  This arrangement makes it possible to give angulation to the bores and thus to give an inclination inwardly to the final fixing screws.

Avantageusement, la traverse 6 est plus large au niveau de la branche supérieure qu'au niveau de la branche inférieure.  Advantageously, the crossbar 6 is wider at the upper branch than at the lower branch.

Pour renforcer la résistance de la plaque, la jonction entre les branches 4 5 et la traverse 6 s'effectue suivant des rayons arrondis venant de construction.  To strengthen the strength of the plate, the junction between the branches 45 and the crossbar 6 is made according to rounded radii coming from construction.

L'exemple illustré aux dessins représente une plaquette gauche.  The example shown in the drawings represents a left plate.

La réalisation de l'ostéotomie nécessite une plaquette droite orientée en sens inverse.  The realization of the osteotomy requires a straight plate oriented in the opposite direction.
