Abstract
Equipment includes bony anchoring members, one or two linking rods, intended to be connected to these anchoring members, and parts for connecting the rod(s) to the anchoring members; at least one anchoring member includes a proximal stud articulated with respect to a base portion enabling bony anchoring; clamping elements enable assembly of the connecting part on the anchoring member. The proximal stud includes a surface forming an axial stop, against which the connecting part is intended to rest, and the clamping elements clamp this connecting part against this surface which is positioned so that the connecting part, when clamped there against, is not clamped against the base portion so that there remains, after clamping, a possibility of articulated backlash of the proximal stud with respect to the base portion.
