Abstract: An equipment includes at least a shoring rod and at least an anchoring assembly of the shoring rod to a vertebra; each anchoring assembly comprises a base integral with a hook which has substantially planar part, extending in a parallel plane, or forming a slight angle, less than 15 degrees, with the base. The base has a hole which runs right through it, having an oblong cross-section, and the anchoring assembly comprises a hook-shaped component whereof the part corresponding to the base of the hook is linked to a threaded rod capable of being engaged in the hole with the possibly of pivoting about an axis and of displacement in the plane, and capable of receiving a screw.

Abstract: The invention relates to a plate (2) with a slot (7), adjacent to at least one hole (4, 6) therein, which traverses the whole of said plate and which extends along said hole (4, 6) on a part of the perimeter of said hole (4, 6). The hole (4, 6) and slot (7) thus define a band of material (8) between them which is flexibly elastic. The band (8) comprises locking means (9) on the edge thereof defining the hole (4, 6), which project towards the interior of the hole (4, 6). The object (3), for placement in said hole (4, 6), comprises complementary locking means (10) which, when said object (3) is engaged in said hole (4, 6) come into engagement with the locking means (9) on the band of material (8) such as to connect said object (3) to the plate (2) or to fix said plate (2) to a bone.
