Abstract: front page image
(EN)This invention relates to devices, systems and methods for the internal fixation of bone fractures, and particularly, to intramedullary fracture fixation devices. An IM rod preferably is provided with multiple curved sections in different planes preferably designed to conform with the long bones of a patient, both during insertion and in the rod's final position in the long bone. In addition, the overlap of portions of the curved sections results in a co-planar curvature of portions of the IM rod which assist in the insertion process by guiding the proper rotation of the IM rod as it is inserted into the bone. Spiraling flutes extending down the distal portion of the rod also assist in properly guiding and orienting the rod about its longitudinal axis during insertion such that the appropriate segment of the curved rod conforms with the appropriate portion of the long bone at the appropriate place.
(FR)L'invention concerne de manière générale des dispositifs, des systèmes et des procédés destinés à la fixation interne de fractures d'os et notamment à des dispositifs de fixation de fractures intramédullaires tels que ceux utilisés pour traiter les fractures d'os longs. Une tige intramédullaire comporte plusieurs sections curvilignes dans des plans différents, destinées de préférence à se conformer aux os longs d'un patient, que ce soit pendant l'insertion de la tige dans l'os long d'un patient ou en position finale. En outre, le chevauchement des parties des sections curvilignes assure une courbure coplanaire des parties de la tige IM, qui facilite le processus d'insertion grâce au guidage de la rotation propre de la tige IM pendant que celle-ci est insérée dans l'os. Les cannelures spiralées qui s'étendent vers le bas depuis la partie distale de la tige facilitent également le guidage approprié et l'orientation de la tige par rapport à son axe longitudinal lors de l'insertion, de manière à ce que le segment approprié de la tige curviligne épouse la partie appropriée de l'os long à l'endroit approprié.
