Abstract

L'invention porte sur un dispositif et un procédé de fixation de fractures, lequel dispositif comprend une vis (10) comportant une tige munie d'une partie d'extrémité sur la surface extérieure de laquelle est configuré un filetage (12), et comportant un alésage traversant. L'alésage traversant comprend deux parties d'alésage de diamètre différent (16, 17). Le saut de diamètre (18) entre les deux parties d'alésage précitées est agencé de façon qu'il est adjacent à l'extrémité de la vis munie du filetage. Ce saut de diamètre peut soutenir une pièce rapportée (30, 50) qui soutient à son tour une broche en polymère (20, 40) lorsque cette dernière est mise sous pression dans la vis. La pression, conjointement à l'application d'une vibration ultrasonore, fluidifie la broche en polymère et comprime le matériau à travers des trous ménagés dans la paroi de la vis.
