SPINAL IMPLANT WITH A LOCKABLE PATELLA LINK

摘要

The invention relates to a spinal implant (100) including: a part (110) for anchoring into a vertebra, comprising first linking means (112); and a mounting part (120) including, on the inside thereof, an axial recess (151) for transversely receiving a linking rod (30), the axial recess (30) being defined on the side of the anchoring part (110) by a bottom (156), as well as a second linking means (140, 53) engaging with said first linking means so as to form a patella link between said anchoring part and said mounting part. According to the invention, the spinal implant comprises retaining means (154) in the vicinity of the bottom of the axial recess of said mounting part for attaching a blocking element (130) in a fixed so-called blocking position in which the patella link formed by said first and second linking means is blocked so as to render said anchoring and mounting parts rotationally fixed relative to one another about at least two orthogonal axes.
