Abstract

La présente invention concerne le domaine général des dispositifs d'ostéosynthèse, de type vis ou broche associée ou non à une plaque d'ostéosynthèse, et comprenant des moyens structurels supplémentaires aptes à verrouiller en rotation ladite vis ou ladite broche, afin de prévenir tout phénomène de dévissage et ainsi maintenir la compression dudit dispositif sur l'os, et le cas échéant sur ladite plaque d'ostéosynthèse. Conformément à l'invention, le dispositif d'ostéosynthèse comporte des moyens structurels supplémentaires comprenant au moins un logement (8) aménagé sur la vis (1) sur la broche, qui est apte à recevoir, après vissage de ladite vis (1) ou de ladite broche dans le matériau osseux (15), un élément structurel rapporté (2) ici en forme de clavette. L'élément structurel (2), positionné dans ledit logement (8), est adapté pour s'étendre en partie hors de l'encombrement de la vis (1) ou de la broche, cela dans le matériau osseux de réception (15).
