Abstract
Description
La présente invention concerne un élément de soutien en forme de tuyau pour la réduction et la contention des frac- tures d'os longs, empêchant la rotation des fragments osseux l'un par rapport à l'autre. The present invention relates to a pipe-like support element for the reduction and containment of long bone fractures, preventing rotation of the bone fragments relative to each other.
La grande majorité des éléments de soutien connus de ce genre n'empêchent pas d'une façon adéquate la rotation des fragments d'un os fracturé et les éléments de soutien de ce genre qui empêchent cette rotation nécessitent une utilisation excessive de rayons X ce qui comporte un danger pour les personnes se trouvant dans la salle d'opération. The vast majority of known support elements of this kind do not adequately prevent rotation of fractured bone fragments and such support elements that prevent this rotation require excessive use of X-rays which poses a danger to persons in the operating room.
Lrélément de soutien selon l'invention permet d'éviter ces inconvénients. Il est en effet formé de deux parties principales I et IL. Les deux parties peuvent glisser l'un dans l'autre et comportent un système les empêchant de tourner l'unepar rapport à l'autre. La partie It présente un diamètre inférieur a' la partie r et se terminant distalement par quatre lamelles assez élastiques pour s'ouvrir en éventail dès leur sortie de la partie I en vue de leur ancrage dans le spongieux du fragment distal de l'os fracturé empêchant sa rotation. La rotation du fragment proximal de l'os est empêchée par une pièce fixée sur le bout proximal de la partie I et sur l'os. The support element according to the invention makes it possible to avoid these drawbacks. It is in fact formed of two main parts I and IL. The two parts can slide into each other and have a system preventing them from turning relative to each other. The part It has a diameter smaller than the part r and ending distally by four lamellas sufficiently elastic to open in a fan shape as soon as they leave part I for their anchoring in the cancellous part of the distal fragment of the fractured bone preventing its rotation. The rotation of the proximal bone fragment is prevented by a part fixed on the proximal end of part I and on the bone.
Son introduction, étant aussi simple que les éléments de soutien de ce genre, se fait en perçant l'os au niveau de sa partie renflée afin de créer un passage dans le canal médullaire. La partie 11 étant introduite dans la partie I, l'élément de soutien dons son ensemble est introduit dans le canal médullaire et une fois arrivé dans la région où ce canal médullaire s'élargit, on enfonce seulement la partie IS dont l'extrémité distale s'ouvre en éventail, à cause de l'élasticité des lamelles, dès la sortie- de la partie r. Ce dispositif automatique bloque la rotation du fragment distal de l'os fracturé en diminuant au minimum les contrôles radiologiques contrairement à certains éléments de soutien de ce genre. Its introduction, being as simple as the support elements of this kind, is done by piercing the bone at the level of its swollen part in order to create a passage in the medullary canal. Part 11 being introduced into part I, the support element for the whole is introduced into the medullary canal and once arrived in the region where this medullary canal widens, only the IS part is inserted, the distal end of which opens in a fan shape, due to the elasticity of the slats, from the exit - from part r. This automatic device blocks the rotation of the distal fragment of the fractured bone by minimizing radiological controls, unlike certain support elements of this kind.
te blocage du fragment proximal est obtenu en fixant la pièce 3 à ltextrémité proximale de la partie I et à l'os sou contrôle de la vue et sans aucune irradiation,
Tel qu'il est représenté, l'élément de soutien suivant une coupe longitudinale comporte deux parties t et It. blocking the proximal fragment is obtained by attaching part 3 to the proximal end of part I and to the bone under visual control and without any irradiation,
As shown, the support element in a longitudinal section has two parts t and It.
Le bout proximal de la partie T comporte un épaississement (4) empêchant la pièce (3) de glisser le long de la partie r. Cet épaississement est suivi d'une région héxagonale (5) dans laquelle vient s'emboiter l'hexagone de la pièce 3. Cet héxagone est suivi d'une région filetée permettant la mise en place d'un écrou pour bien fixer la pièce 3 à la partie I. The proximal end of the part T has a thickening (4) preventing the part (3) from sliding along the part r. This thickening is followed by a hexagonal region (5) in which the hexagon of the part 3 fits. This hexagon is followed by a threaded region allowing the fitting of a nut to properly fix the part 3 in Part I.
Une coupe suivant B B' montre les épaississements (6) et les dépressions (7) des parties T et Tt. Ce système empêche les deux parties de faire des mouvements de rotation l'une par rapport à l'autre. A section along B B 'shows the thickenings (6) and the depressions (7) of the parts T and Tt. This system prevents the two parties from making rotational movements with respect to each other.
Une coupe suivant C C' montre la forme de la partie II au niveau de l'insertion des quatre lamelles a, b, c, d. A section along C C 'shows the shape of part II at the insertion of the four strips a, b, c, d.
Chaque lamelle ( D D' ) est formée de la lamelle proprement dite ( 10) et d'un épaississement (11) de chaque côté. Each strip (D D ') is formed of the strip proper (10) and a thickening (11) on each side.
