Abstract
Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente, invention est utilisée exceptionnellement comme moyen d'ostéosynthèse chez l'enfant. Les indications sont réservées aux patients porteurs d'une pathologie osseuse, le plus souvent constitutionnelle, entraînant des déformations et une fragilisation pour lesquelles il est souhaitable de mettre en place, de façon permanente un tuteur métallique palliant aux défauts mécaniques du squelette. The present invention is used exceptionally as a means of osteosynthesis in children. The indications are reserved for patients with a bone pathology, most often constitutional, resulting in deformations and embrittlement for which it is desirable to permanently install a metal support compensating for the mechanical defects of the skeleton.
La présente invention peut également être utilisée pour le traitement des pseudarthroses congénitales du tibia, dans l'ostéopétrose, pour les atteintes de la dysplasie fibreuse et également chez certains patients atteints de troubles moteurs sévères, de raideurs articulaires, victimes parfois de fractures à répétition avec des déformations squelettiques. The present invention can also be used for the treatment of congenital non-union of the tibia, in osteopetrosis, for attacks of fibrous dysplasia and also in certain patients suffering from severe motor disorders, joint stiffness, victims sometimes of repeated fractures with skeletal deformities.
On connaît l'installation de broches classiques introduites dans le canal médullaire de tous les os longs, avec l'inconvénient d'avoir une broche fixe ne tenant pas compte de la croissance de l'enfant. We know the installation of conventional pins introduced into the spinal canal of all long bones, with the disadvantage of having a fixed pin that does not take into account the growth of the child.
Le système d'enclouage centro médullaire télescopique, objet de l'invention, permet, après avoir procédé à un certain nombre d'ostéotomies, de traverser et de composer une brochette osseuse avec la partie femelle impactée d'un côté venant rejoindre de l'autre côté la partie mâle. Visiblement l'os est redressé, il se solidifiera avec le temps et l'implant étant télescopique, il grandira avec la croissance de l'enfant. The telescopic centro-medullary nailing system, object of the invention, allows, after having carried out a certain number of osteotomies, to cross and compose a bone skewer with the female part impacted on one side coming to join the on the other side the male part. Obviously the bone is straightened, it will solidify over time and the implant being telescopic, it will grow with the growth of the child.
L'invention est décrite ci-après selon un mode de réalisation particulier non limitatif en regard des dessins annexés sur lesquels : - La figure 1 représente une vue en coupe du matériel installé dans un os long signalé en pointillés. The invention is described below according to a particular non-limiting embodiment with regard to the accompanying drawings in which: - Figure 1 shows a sectional view of the equipment installed in a long bone indicated by dotted lines.
- La figure 2 représente le boulon de verrouillage de la partie femelle. - Figure 2 shows the locking bolt of the female part.
- La figure 3 représente l'une et l'autre extrémités du matériel avec son logement central. - Figure 3 shows both ends of the equipment with its central housing.
Selon un mode de réalisation particulier de l'invention, les deux pièces principales (1,2) coulissent l'une dans l'autre. Il sera nécessaire, afin de s'adapter à la morphologie de chaque patient, de faire différents diamètres et différentes longueurs. According to a particular embodiment of the invention, the two main parts (1,2) slide one inside the other. In order to adapt to the morphology of each patient, it will be necessary to make different diameters and different lengths.
L'implant télescopique sera préférentiellement composé de trois pièces : deux pièces coulissant l'une dans l'autre (1,2) et un boulon de verrouillage. The telescopic implant will preferably be composed of three parts: two parts sliding one inside the other (1,2) and a locking bolt.

Selon un mode de réalisation particulier de l'invention, la partie mâle (2) possède à son extrémité une plaquette rectangulaire (4) soudée à celle-ci, servant d'appui sur l'extrémité osseuse (5) en pointillé (fig. 1). Cette partie mâle est impactée avec un instrument à choc se mettant dans le logement usiné au centre de la plaquette (6). According to a particular embodiment of the invention, the male part (2) has at its end a rectangular plate (4) welded to the latter, serving as support on the bone end (5) in dotted lines (fig. 1). This male part is impacted with an impact instrument placed in the machined housing in the center of the plate (6).
Selon un mode de réalisation particulier de l'invention, la partie femelle (1) possède à son extrémité une partie taraudée intérieure (7) dans laquelle s'installe un boulon métallique fileté (3), possédant sur un côté un méplat (8) représenté de profil (fig. 2) et possédant également un logement central d'impaction (6). Lorsque la partie femelle est installée dans l'os, le boulon (fig. 2) est mis en place et, afin de le rendre prisonnier, il suffit d'écraser légèrement le tube à l'endroit du méplat. According to a particular embodiment of the invention, the female part (1) has at its end an internal threaded part (7) in which a threaded metal bolt (3) is installed, having on one side a flat (8) shown in profile (fig. 2) and also having a central impaction housing (6). When the female part is installed in the bone, the bolt (fig. 2) is put in place and, in order to make it captive, it is enough to slightly crush the tube at the place of the flat.
On constate qu'après l'installation du matériel, l'os est parfaitement redressé et offre au patient l'asurance de conserver un os droit pendant toute sa croissance puisque celui-ci est télescopique.It is noted that after the installation of the material, the bone is perfectly straightened and offers the patient the assurance of keeping a straight bone throughout its growth since it is telescopic.
