DEVICE FOR ATTACHING A PROTHETIC OR OSTEOSYNTHESIS BODY TO A BONE.

摘要

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.
