L'invention concerne un dispositif (10) et un procédé pour la localisation d'un pédicule et la résection du corps vertébral correspondant. Le dispositif (10) selon l'invention comprend un ostéotome (12) pourvu d'un élément coupant (18) servant à enlever une section d'os de taille permettant d'accommoder une portion d'implant, ainsi qu'un chercheur de pédicule (14) pourvu, à l'extrémité proximale (22), d'un manche (20) pour manipuler le chercheur de pédicule (14) et, à l'extrémité distale (26), d'un localisateur de pédicule (24) relié au manche (20) par une tige (28). Le dispositif selon l'invention est caractérisé en ce que le chercheur de pédicule (14) comprend également un guide d'ostéotome (30) situé sur la tige (28), configuré et dimensionné de manière à engager par glissement au moins une partie de l'ostéotome (12).
