Abstract

Vis pour ostéosynthèse comportant un indexage angulaire par rapport au tournevis et à compatibilité universelle La présente invention concerne une vis de serrage (6) pour ostéosynthèse comportant au moins un filetage (7,10) suivant une axe principal (X) et à son extrémité dite apicale (11) une empreinte (12) présentant autour dudit axe principal (X) des formes régulières réparties angulairement, adaptées pour recevoir des formes complémentaires d’un tournevis (19) s’engageant dans ladite empreinte (12), remarquable en ce que l’empreinte (12) de la vis (6) comporte au moins trois formes régulières (13) dont les sommets sont inscrits dans un cercle dit cercle circonscrit (30) et au moins deux sommets adjacents de l’empreinte (21) sont reliés pour former un lobe convexe dit d’indexation (16) dont le rayon de courbure est égal au rayon du cercle circonscrit (30).
