Abstract

L'invention a pour objet un implant d'ostéosynthèse pour fixer un os fracturé (29). Cet implant comprend un clou (8) comportant plusieurs lames en spirale (10, 12) qui partagent un axe hélicoïdal commun. Au moins deux de ces lames (10, 12) définissent un angle (17) inférieur à 180° dans un plan perpendiculaire à l'axe hélicoïdal. Dans un mode de réalisation préféré, deux lames (12) du clou (8) sont inclinées en direction de leur partie proximale, et deux autres lames (10) présentent une épaisseur uniforme. Les lames sont enroulées en spirale selon un angle d'au moins 30°. Une canulation (24) s'étend au centre du clou (8) pour recevoir un fil-guide. Le clou (8) peut se mettre en prise, par coulissement, avec un élément de fixation (26, 40) qui peut être fixé à une partie allongée (28) de l'os (29), de la même façon qu'une plaque latérale (26) ou un clou intramédullaire (40). Dans une orientation d'implantation préférée, la partie proximale des lames inclinées (12) est parallèle à la partie allongée (28) de l'os (29), et une partie proximale des lames uniformes (10) est perpendiculaire à ces dernières.
