FIXATEUR EXTERNE POUR L'OSTEOSYNTKESE
PERCUTANEE DE8 FRACTURES EXTRA-CAPSULAIRES
DE L'EXTRENITE 8UPERIEURE DU FEMUR OU
FRACTURES PERTROCHANTERI ENNES
L'ostéosynthèse des fractures pertrochantériennes est habituellement assurée par un matériel interne (clou, plaque ou vis-plaque). Leur mise en place implique une intervention chirurgicale "à ciel ouvert", pour le déposer contre l'extrémité supérieure du fémur.EXTERNAL FIXER FOR OSTEOSYNTKESE
PERCUTANEOUS OF 8 EXTRA-CAPSULAR FRACTURES
OF THE 8UPERIOR EXTRENITY OF THE FEMUR OR
ENTRIES PERTROCHANTERI FRACTURES
Osteosynthesis of pertrochanteric fractures is usually provided by internal material (nail, plate or screw-plate). Their placement involves an "open" surgical intervention, to deposit it against the upper end of the femur.
Cette opération chirurgicale est hémorragique et demande du temps. Elle est habituellement bien supportée, mais les grands vieillards et tous sujets à risque peuvent bénéficier d'un dispositif placé en percutané au moyen d'un fixateur externe. Ce procédé est rapide et moins invasif. Il doit voir ses indications se développer dans l'avenir, du fait de l'accroissement de l'âge des opérés, du refus des transfusions sanguines et des risques septiques engendrés par une intervention chirurgicale avec ouverture large. This surgical operation is hemorrhagic and takes time. It is usually well tolerated, but the elderly and all subjects at risk can benefit from a device placed percutaneously by means of an external fixator. This process is quick and less invasive. He must see his indications develop in the future, due to the increase in the age of operated patients, the refusal of blood transfusions and the septic risks engendered by a surgical procedure with wide opening.
Le dispositif est un fixateur externe réservé à l'ostéosynthèse de l'extrémité supérieure du fémur. Sa conception est établie sur la combinaison des exigences mécaniques nécessaires au maintien d'une telle fracture et des exigences de confort permettant de rendre supportable le port du matériel pendant une période d'au moins deux mois. L'invention est décrite ci-dessous en référence au dessin schématique annexé représentant ce fixateur dans une forme de réalisation non limitative. The device is an external fixator reserved for osteosynthesis of the upper end of the femur. Its design is established on the combination of mechanical requirements necessary to maintain such a fracture and comfort requirements making it possible to bear the wearing of equipment for a period of at least two months. The invention is described below with reference to the attached schematic drawing showing this fixer in a non-limiting embodiment.
La figure 1 en est une vue en perspective, alors qu'il est mis en place sur l'extrémité d'un fémur et les figures 2 et 3 sont, respectivement, des vues en coupe selon II-II et III-III de figure 1. Figure 1 is a perspective view, while it is in place on the end of a femur and Figures 2 and 3 are, respectively, sectional views along II-II and III-III of figure 1.
Le dispositif de base (figure 1) est constitué par une barre de solidarisation curviligne 1 occupant de préférence le quart d'un cercle, visant à épouser la région antéro-externe de la hanche. En effet, le dispositif de base solidarise deux groupes de fiches 2,3, placés dans un plan perpendiculaire l'un par rapport à l'autre : un premier groupe de fiches 2 est introduit dans le col du fémur, selon une inclinaison de sensiblement 1300 par rapport à l'axe de la diaphyse fémorale et dans un plan frontal. Le deuxième groupe est composé de deux ou trois fiches 3, introduites d'avant en arrière dans le plan sagittal et à la partie haute de la diaphyse fémorale. The basic device (Figure 1) is constituted by a curvilinear connection bar 1 preferably occupying a quarter of a circle, aiming to match the antero-external region of the hip. Indeed, the basic device secures two groups of plugs 2,3, placed in a plane perpendicular to each other: a first group of plugs 2 is introduced into the neck of the femur, at an inclination of substantially 1300 with respect to the axis of the femoral shaft and in a frontal plane. The second group is made up of two or three sheets 3, inserted from front to back in the sagittal plane and in the upper part of the femoral diaphysis.
La barre de solidarisation 1 est composée de deux pièces 4,5, emboitées l'une dans l'autre afin de s'adapter au volume de la hanche et aux variations de distance entre l'extrémité des deux groupes de fiches 2,3. Ces deux pièces 4,5 peuvent être verrouillées entre elles à la longueur voulue par un moyen de serrage et, notamment,le serrage de deux vis 6. The joining bar 1 is made up of two parts 4,5, fitted one inside the other in order to adapt to the volume of the hip and to the variations in distance between the ends of the two groups of plugs 2,3. These two parts 4,5 can be locked together to the desired length by a tightening means and, in particular, the tightening of two screws 6.
Aux deux extrémités de la barre de solidarisation 1 se trouvent les pièces de fixation 7,8 de l'extrémité de chacun des groupes de fiches 2,3 (figure 2). At the two ends of the fastening bar 1 are the fixing pieces 7,8 of the end of each of the groups of plugs 2,3 (Figure 2).
La pièce 7 fixe les fiches 2 introduites dans le col du fémur. Elle est composée de deux parties 7a,7b, dont les faces en regard comprennent des évidements hémicylindriques pour recevoir les fiches 2. Les deux parties 7a,7b de cette pièce 7 sont solidarisées entre elles par un moyen de serrage tel qu'une vis 9 qui est vissée dans le corps de la barre de solidarisation 1. Piece 7 fixes the sheets 2 inserted in the neck of the femur. It is composed of two parts 7a, 7b, the opposite faces of which include semi-cylindrical recesses for receiving the plugs 2. The two parts 7a, 7b of this part 7 are secured to each other by a tightening means such as a screw 9 which is screwed into the body of the joining bar 1.
Ce montage permet le pivotement de la pièce 7 sur l'extrémité de la barre de solidarisation 1, ce qui permet de l'orienter à volonté pour régler la direction des broches 2 introduites dans le col du fémur. This assembly allows the part 7 to pivot on the end of the securing bar 1, which allows it to be oriented at will to adjust the direction of the pins 2 introduced into the neck of the femur.
A l'autre extrémité de la barre de solidarisation curviligne 1 (figure 3) se trouve la pièce 8 qui assure le serrage des fiches antérieures et sagittales 3. Elle présente les mêmes caractéristiques générales que la pièce 7, excepté que ses évidements hémicylindriques qui admettent les fiches 3 sont dans un plan sagittal et vertical et qu'ils peuvent être au nombre de trois. At the other end of the curvilinear fastening bar 1 (FIG. 3) is the part 8 which ensures the tightening of the anterior and sagittal sheets 3. It has the same general characteristics as the part 7, except that its semi-cylindrical recesses which admit sheets 3 are in a sagittal and vertical plane and they can be three in number.
La pièce 8 est également composée de deux parties 8a,8b. Elle est en outre montée pivotante et verrouillable à la barre de solidarisation 1, par le même moyen que pour la pièce 7, à savoir une vis 10 lui permettant aussi d'adapter l'orientation des fiches (3). The part 8 is also composed of two parts 8a, 8b. It is also pivotally mounted and lockable to the fastening bar 1, by the same means as for the part 7, namely a screw 10 also allowing it to adapt the orientation of the plugs (3).
La forme du dispositif 1 de base et de ses accessoires peut varier : forme quadrangulaire (figure 1) ou circulaire (figures 2 et 3) en coupe transversale selon les besoins mécaniques, fonctionnels, esthétiques ou économiques. L'essentiel est que le dispositif de base se présente sous une forme courbe adaptée à la face antéro-externe de la hanche. The shape of the basic device 1 and of its accessories can vary: quadrangular shape (Figure 1) or circular (Figures 2 and 3) in cross section according to mechanical, functional, aesthetic or economic needs. The main thing is that the basic device is in a curved shape adapted to the antero-external aspect of the hip.
