CA 2243152

A dowel (300) is provided by obtaining a plug from the shaft (diaphysis) of various tong bones. The dowel (300,) has an infra-medullary canal (30) which can be packed with any of a variety of osteogenic materials. The dowel (300) has a cortical surface (10) into which an instrument attachment hole (15) may be machined and onto which an alignment marl; (16) may be inscribed for proper orientation of the infra-medullary canal (30) or a driver slot (56) which may be used to assist in further machining of the bone dowel (300). The dowel (300) has a chamfered insertion end and has improved biomechanical and vertebral fusion induction properties as compared to standard dowles known in the art. A threaded (31) or grooved (32) dowel (300) and an apparatus (400) for efficient production thereof are also provided.

Cette invention concerne une cheville (300) qui est obtenue à partir d'un morceau du corps (diaphysis) de divers os allongés, laquelle cheville (300) possède un canal intra-médullaire (30) qui peut être rempli de divers types de matériaux ostéogènes. Cette cheville (300) possède une surface corticale (10) dans laquelle peut être usiné un trou (15) de fixation d'un instrument, et sur laquelle peut être inscrit un repère d'alignement (16) afin d'assurer la bonne orientation du canal intra-médullaire (30), ladite surface pouvant également comporter une fente d'entraînement (56) permettant de faciliter l'usinage complémentaire de la cheville osseuse. Cette cheville (300) comporte une extrémité d'insertion chanfreinée, et possède de meilleures propriétés mécaniques et d'induction de fusion vertébrale que les chevilles classiques connues. Cette invention concerne également une cheville (300) filetée (31) ou comportant des gorges (32), ainsi qu'un appareil (400) efficace destiné à la fabrication de ces chevilles.
