The invention concerns an equipment comprising two shoring rods, members for anchoring said two rods to the vertebrae, at least a crosspiece () in two parts () and members () assembling said crosspiece () to the shoring rods. The invention is characterised in that one of the crosspiece parts () comprises a spherical head () and a thread () adjacent to said head (); the other crosspiece part () comprises a spherical bulging end (), defining internally a spherical cavity () adapted to receive said head (), and each crosspiece () comprises a nut () designed to co-operate with said thread (), including further a spherical seat () with a shape matching that of the wall () delimiting the cavity (). The invention also concerns plates (for anchoring the equipment to the sacrum.

Vertebral arthrodesis equipment

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.
