Abstract

Ce dispositif (2) comporte un corps prothétique ou d'ostéosynthèse (10) qui délimite un trou traversant (11) de réception d'un organe allongé d'ancrage osseux (20), ce trou formant dans sa partie distale (12A) un appui pour le côté distal (22A) d'une tête (22) de l'organe d'ancrage suivant la direction longitudinale (Y-Y) de cet organe. Afin de bloquer la tête dans le trou de manière efficace et simple, un couvercle amovible (30) est prévu pour fermer le trou, en étant adapté pour être fixé au corps par emmanchement dans la partie proximale (12B) du trou suivant la direction de l'axe (X-X) de ce trou, puis par rotation sur lui-même d'une fraction de tour autour de cet axe pour engager des ergots saillants (32) du couvercle, répartis suivant sa périphérie, dans une gorge complémentaire (14) qui est délimitée par le corps suivant la périphérie intérieure du trou. Lorsque le couvercle est ainsi fixé au corps, il forme un appui, direct ou indirect, pour le côté proximal (22B) de la tête suivant la direction longitudinale de l'organe d'ancrage.This device (2) comprises a prosthetic or osteosynthesis body (10) which delimits a through hole (11) for receiving an elongated bone anchoring member (20), this hole forming in its distal part (12A) a support for the distal side (22A) of a head (22) of the anchoring member in the longitudinal direction (YY) of this member. In order to block the head in the hole in an efficient and simple manner, a removable cover (30) is provided to close the hole, being adapted to be fixed to the body by fitting in the proximal part (12B) of the hole in the direction of the hole. the axis (XX) of this hole, then by rotation on itself a fraction of a turn around this axis to engage projecting lugs (32) of the cover, distributed along its periphery, in a complementary groove (14) which is delimited by the body along the inner periphery of the hole. When the cover is thus fixed to the body, it forms a support, direct or indirect, for the proximal side (22B) of the head in the longitudinal direction of the anchoring member.
