Abstract:
The invention concerns an osteosynthesis system, comprising at least a linking element (1) in the form of a rod, at least two fixing elements each capable of being anchored in a vertebra, a locking screw (13). The invention is characterised in that the base of the head (5) has a general horse-saddle shape, and the head (5) has guide means for an independent closure component designed to be fixed on the head (5) after the linking element (1) has been positioned in the fork of the head (5), said closure component (3) being generally U-shaped whereof the branches are urged to co-operate with the branches of the fork-shaped part of the head (5) and whereof the base comprises an internal thread for co-operating with the locking screw (13) and the guide means provided on the head (5) is formed by an arc-shaped shoulder on the outer side surfaces of the fork-shaped part. The invention also concerns an ancillary and an element for fixing such a system.
