Title (EN) BOTTOM-LOADING POLYAXIAL BONE ANCHORING SYSTEM
(FR) SYSTEME D'ANCRAGE OSSEUX POLYAXIAL A CHARGEMENT PAR LE DESSOUS
Abstract: front page image
(EN)The invention concerns a polyaxial bone anchoring system (1) comprising a bone anchoring member provided with a hemispherical head (21) and a tubular barrel (3) comprising a base (33) traversed by an axial channel of which the cross section is greater than the cross section of the hemispherical head (21), said channel having, in the lower part, a frustoconical housing (9) that widens in the direction opposite the hemispherical head (21) and, upstream from the frustoconical housing (9), a transverse shoulder (11) of which the internal cross-section is substantially equal to the cross-section of the hemispherical head (21), the system further comprising a conical split ring (4) of which the outer surface matches the inner surface of the frustoconical housing (9) and of which the minimum cross-section when idle is smaller than the nominal cross-section of the hemispherical head (21), said ring being made from a deformable material.
(FR)L'invention concerne un système d'ancrage osseux polyaxial (1) comprenant un élément d'ancrage osseux pourvu d'une tête hémisphérique (21) et un fut tubulaire (3) comportant une embase (33) traversée par un canal axial d'une section supérieure à la section de la tête hémisphérique (21),ledit canal présentant, en partie inférieure, un logement tronconique (9)s'élargissant en direction opposée à la tête hémisphérique (21) et, en amont du logement tronconique (9), un épaulement (11) transversal d'une section intérieure sensiblement égale à la section de la tête hémisphérique (21),le système comportant en outre une bague fendue (4)conique de surface extérieure conjuguée à la surface intérieure du logement tronconique (9)et de section minimale au repos inférieure à la section nominale de la tête hémisphérique (21), ladite bague étant réalisée en un matériau déformable.
