The instrumentation comprises 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) has an opening (7) therethrough, said opening (7) has dimensions greater than a cross-section dimension of a machine thread section (4) of said bone-anchoring element (2). A mechanism (10) is adapted to affix said bone-anchoring element (2) in said opening(7). said mechanism (10) comprising a pressure element (10) received by said bone-anchoring element (2); 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) having at its bottom side a recess (12) for receiving the longitudinal element (1). The longitudinal element (1) is clamped against said support (32), whereas the force of the support (32) on the longitudinal element (1) is approximately parallel to the axis (D) of the bone-anchoring element (2). <IMAGE> |
