1. An assembly for rectifying vertebrae, comprising:
two bone anchoring means intended to be implanted on a same vertebra;
a structure for bridging the bone anchoring means to one another, the bridging structure, which is implantable, comprising a triangulation bar and connection means for connecting the triangulation bar to each bone anchoring means,
a correction instrument mounted on the triangulation bar;
means for locking the triangulation bar on the bone anchoring means via the connection means, the triangulation bar thus forming, with the bone anchoring means, a rigid triangular assembly, wherein the connection means comprise two connectors each comprising a first passage area defining a longitudinal passage axis for the triangulation bar and a second passage area arranged to receive one of the bone anchoring means, the second passage area having an oblong form oriented parallel to the longitudinal passage axis of the first passage area, the connectors forming the means for adjusting the angular position of the correction instrument; and
means for adjusting an angular position of the correction instrument relative to the vertebra at a determined angle.
