Abstract

The present invention relates to a clip plate permitting stable osteosynthesis in tibial osteotomies, characterised in that it comprises a double anchoring system, namely compression by means of the clip (1) and stabilisation by means of a screw-type divergent locking system (2), this allowing a solid hold of the fragments, preventing any movement in the osteotomy plane.

Description

La présente invention à pour objet la synthèse des ostéotomies tibiales supérieures du type de valgisation, emportant un coin à base externe. The present invention relates to the synthesis of superior tibial osteotomies of the valgization type, taking away a wedge with an external base.

Cette plaque agrafe vient s'appliquer contre la métaphyse supéro externe du tibia à cheval sur le trait d'ostéotomie
L'ostéotomie tibiale permet, par résection d'un coin osseux et impaction immédiate des fragments, de réorienter l'axe de la jambe. Ceci permet de modifier la charge de chacun des deux compartiments du genou, donc de soulager le compartiment le plus atteint au détriment du compartiment le plus sain. Cette technique est utilisée dans le traitement des gonarthroses latérales ou plus souvent médiales. La résection se fait alors sur le bord externe de l'os.
This staple plate is applied against the upper outer metaphysis of the tibia straddling the osteotomy line
The tibial osteotomy allows, by resection of a bony wedge and immediate impaction of the fragments, to reorient the axis of the leg. This makes it possible to modify the load of each of the two knee compartments, therefore to relieve the most affected compartment at the expense of the healthiest compartment. This technique is used in the treatment of lateral or more often medial osteoarthritis. Resection is then done on the outer edge of the bone.

Lors de cette intervention, il est nécessaire de maintenir les fragments osseux l'un contre l'autre de façon stable. La présente invention à pour but de permettre une impaction calculée, compressive au niveau du foyer d'ostéotomie et une stabilité immédiate autorisant une appui contrôlé par le patient lui même. During this intervention, it is necessary to hold the bone fragments against each other in a stable manner. The present invention aims to allow a calculated, compressive impaction at the osteotomy site and immediate stability allowing support controlled by the patient himself.

On propose un matériel original dans sa structure, sa forme et sa fixation sur les segments osseux. We offer original material in its structure, shape and fixation on the bone segments.

La struture de l'implant est faite de TITANE pur (T40). Ce matériau présente des avantages importants en ce qui concerne son élasticité et sa tolérance biologique. The implant structure is made of pure TITANIUM (T40). This material has significant advantages with regard to its elasticity and its biological tolerance.

Son élasticité proche de celle de l'os permet une sollicitation osseuse optimale pour l'ostéogénèse et la consolidation. Lors de l'appui, il apparaît des sollicitations alternées prises en charge par l'implant et favorisant la formation d'os. La lyse osseuse, fréquente autour des implants habituels, n'apparaît plus. Its elasticity close to that of bone allows optimal bone stress for osteogenesis and consolidation. During support, it appears alternating stresses supported by the implant and promoting bone formation. Bone lysis, frequent around the usual implants, no longer appears.

Sa tolérance biologique supprime toute réaction défavorable et son ablation n'est plus systématique après consolidation. Its biological tolerance eliminates any adverse reaction and its removal is no longer systematic after consolidation.

La plaque agrafe, monobloc, comporte dans sa forme habituelle, une partie verticale, le corps (3 (fig I)), dont le carrossage en baïonnette (4( fig 2)) est calqué sur le contour de l'extrémité supérieure du tibia. Les deux extrémités supportent chacune un oeillet postérieur (5 (fig 1) et (6 (fig I)) et une lame interne(7(fig l))et(8(fig 1)). The staple plate, monobloc, comprises in its usual form, a vertical part, the body (3 (fig I)), whose camber in bayonet (4 (fig 2)) is modeled on the contour of the upper end of the tibia . The two ends each support a rear eyelet (5 (fig 1) and (6 (fig I)) and an internal blade (7 (fig l)) and (8 (fig 1)).

Les lames donnent à l'ensemble le rôle d' "agrafe" et les oeillets le rôle de "plaque". The blades give the whole the role of "staple" and the eyelets the role of "plate".

La lame supérieure (7 (fig i)) est effilée à son extrémité (9 (fig 1)), permettant une pénétration facile de l'implant dans les premiers centimètres. Il existe une double encoche (10 (fig 1)) autorisant une correction de la rotation avant l'enfoncement définitif. La zone de jonction (11 (fig 1)) avec le bord externe est plus large, bloquant cette rotation une fois la correction et l'impactlon faites Sa section ronde ou ovalaire (12 (fig 5)) évite de rompre les travées d'os spongieux.  The upper blade (7 (fig i)) is tapered at its end (9 (fig 1)), allowing easy penetration of the implant in the first few centimeters. There is a double notch (10 (fig 1)) allowing correction of the rotation before final insertion. The junction zone (11 (fig 1)) with the outer edge is wider, blocking this rotation once the correction and impact have been made Its round or oval section (12 (fig 5)) avoids breaking the spans of cancellous bone.

La lame inférieure (E (fig 1)) est en fait un ergot assez court,
pénétrant dans la diaphyse après contrôle de la rotation et dont le but est de
maintenir une compression. du foyer à la fin de l'impaction. Sa section est
tranchante (13 (fig 3)) pour pénétrer l'os cortical. Il exciste également une #ncoche (14 (fig 1))#, simple, à sa base, empêchant le retrait intempestif de
l'implant et donnant un bloquage cortical.
The lower blade (E (fig 1)) is actually a fairly short lug,
entering the shaft after controlling the rotation and the purpose of which is to
maintain compression. from the hearth to the end of the impaction. Its section is
sharp (13 (fig 3)) to penetrate the cortical bone. There is also a #noche (14 (fig 1)) #, simple, at its base, preventing the untimely withdrawal of
the implant and giving cortical blockage.

Le corps (3( fig 1)), la lame (7 (fig 1)) et l'ergot (8 (fig 1)) forment
une agrafe qui donne une stabilité primaire au foyer d'ostéotomie et une
compression par l'effet de pente (1 (fig 2)) qui existe sur la partie inférieure de
la lame et la partie supérieur de l'ergot.
The body (3 (fig 1)), the blade (7 (fig 1)) and the lug (8 (fig 1)) form
a clip that gives primary stability to the osteotomy focal point and a
compression by the slope effect (1 (fig 2)) which exists on the lower part of
the blade and the upper part of the lug.

Les oeillets (5 (fig 1)) et (6 (fig f)), latéralisés et postérieurs par
rapport au corps de l'implant, sont percés d'un trou permettant un débattement
pour pouvoir mettre une vis et fixer l'ensemble sur la métaphyse.
The eyelets (5 (fig 1)) and (6 (fig f)), lateralized and posterior by
relative to the body of the implant, are drilled with a hole allowing a clearance
to be able to put a screw and fix the whole on the metaphysis.

L'oeillet supérieur (5 (fig 1)) admettra une vis à cortical ou une vis à
spongieux et débattera vers l'arrière et le haut pour "emprisonner" le fragment
supérieur essentiellement dans le plan horizontal.
The upper eyelet (5 (fig 1)) will admit a cortical screw or a
spongy and will tumble back and up to "trap" the fragment
essentially higher in the horizontal plane.

La surface ( 16 (fig 5)) de l'implant au niveau supérieur entre corps et
oeillet est incurvée dans le plan horizontal pour suivre la métaphyse dans sa
partie postérieure.
The surface (16 (fig 5)) of the implant at the upper level between body and
eyelet is curved in the horizontal plane to follow the metaphysis in its
posterior part.

L'oeillet inférieur (6 (fig 1)), moins latéralisé (15 (fig 4)) que le
supérieur, admettra une vis à cortical dont le débattement devra être possible
dans les trois plans de l'espace.
The lower eyelet (6 (fig 1)), less lateral (15 (fig 4)) than the
superior, will admit a cortex screw whose deflection must be possible
in the three planes of space.

La forme de l'implant nécessite l'utilisation d'un modèle pour le côté
droit et d'un modèle pour le côté gauche. L'inversion de chacun de ces modèles
est possible en fonction du choix du chirurgien ou de la morphologie particulière
de la métaphyse tibiale supérieure.
The shape of the implant requires the use of a template for the side
right and a template for the left side. The inversion of each of these models
is possible depending on the choice of the surgeon or the particular morphology
of the superior tibial metaphysis.

Cet implant notamment - par les qualités plastiques du matériau
(TITANE T40) peut être modelé in situ et être mis du côté interne de la
métaphyse tibiale.
This implant in particular - by the plastic qualities of the material
(TITANE T40) can be modeled in situ and placed on the internal side of the
tibial metaphysis.
