Abstract
The instrumentation includes a spinal stabilizing longitudinal element (1) that is adapted to be placed in a generally parallel relationship with the portion of the spine (A) to be treated, a connector (6) having an opening (7) therethrough, a mechanism (10) is adapted to affix said bone-anchoring element (2) in the opening (7); the connector (6) has a hook portion (11) adapted to cooperate with a support (32) of the bone-anchoring element (2) for clamping the longitudinal element (1); the hook portion (11) has at its bottom side a recess (12) for receiving the longitudinal element (1); the longitudinal element (1) is clamped against said support (32), so that the force of the support (32) on the longitudinal element (1) is approximately parallel to the axis (D) of the bone-anchoring element (2).
