Title (EN) OSTEOTOMY WEDGE DEVICE, KIT AND METHODS FOR REALIGNMENT OF A VARUS ANGULATED KNEE
(FR) DISPOSITIF CUNEIFORME, TROUSSE ET PROCEDES D'OSTEOTOMIE POUR LA CORRECTION D'UN GENOU DEFORME EN VARUS
Abstract:
(EN) The invention provides an osteotomy device, a kit, and methods for realigning varus angulated knees. The device involves a substantially wedge shaped body (100) having two intersecting principal surfaces (112, 114) angularly offset. These principal surfaces extend in a direction of a drive axis about a principal plane from an insertion end to a drive surface at a drive end (11). At least one of the principal surfaces is adapted to engage mechanically a surface adjacent thereto. The drive surface is also adapted to receive a force in the direction of the drive axis toward the insertion end. The kit of the present invention includes substantially such an osteotomy device having a cannular opening along its drive axis and an osteotomy pin. A method of the invention involves making a transverse incision partially into the tibia; realigning tibial portions above, and below the incision with respect to each other to create a predetermined angle (A) between opposing faces of the incision, thereby creating a wedge shaped opening (142) providing substantially wedge shaped body having two angularly offset intersecting principal surfaces, wherein at least one of the surfaces is adapted to engage mechanically a surface adjacent thereto; and driving the body into the opening.
(FR) L'invention concerne un dispositif, une trousse et des procédés d'ostéotomie pour la correction d'un genou déformé en varus. Le dispositif comprend un corps sensiblement cunéiforme (100) présentant deux surfaces principales sécantes (112, 114) inclinées qui s'étendent, dans un sens d'un axe d'entraînement autour d'un plan principal, entre une extrémité d'insertion et une surface d'entraînement d'une extrémité entraînement (11). Au moins une des surfaces principales est conçue pour entrer en contact mécanique avec une surface adjacente. La surface d'entraînement est également adaptée pour subir, dans le sens de l'axe d'entraînement, une force s'exerçant vers l'extrémité d'insertion. La trousse de l'invention inclut généralement un tel dispositif d'ostéotomie présentant un orifice tubulaire le long de son axe d'entraînement et une broche d'ostéotomie. Un procédé de l'invention consiste à pratiquer une incision transversale partielle dans le tibia, puis à réaligner les parties du tibia au-dessus et au-dessous de l'incision l'une relativement à l'autre pour obtenir un angle préétabli (A) entre les bords opposés de l'incision, et créer ainsi une ouverture cunéiforme (142). Le procédé consiste ensuite à mettre en place un corps sensiblement cunéiforme ayant deux surfaces principales sécantes inclinées dont au moins l'une est adaptée pour entrer en contact mécanique avec une surface adjacente. Le procédé consiste enfin à insérer ledit corps dans ladite ouverture.
