The pedicle screw (1) for intervertebral support elements (3) consists of a shaft (10) and a head (2) comprising at least two parts (20, 22). The head is formed as a securing means for at least one support element (3). Each support element consists of a piece of a cable-like band (31) and a cylindrical support body (30) with an axial lumen (31″ containing the band. The band is securable outside end surfaces (32) of the support body in the head. The head is formed with a contact surface (23) via which a pressure stress can be exerted on the support body in the band direction, and indeed using the band and in cooperation with a further pedicle screw. A part (20) of the head (2), which is firmly connected to the shaft (10) at the one end of the latter, contains a base groove (21) which is oriented transversally to the shaft and into which the part of the band (31) to be secured or a connecting piece (292) which contains the band can be introduced during the securing of the support element (3) by means of a translatory movement in the direction of the shaft and fixed there.

The invention claimed is: 1. A dynamic stabilization system for a spinal column, the dynamic stabilization system comprising:a first vertebral fastener configured to be secured to a first vertebra, the first vertebral fastener including a head defining a channel;a support element including a spacer having a bore extending therethrough and a flexible member sized to insert through the bore of the spacer; anda first member having at least a portion positionable within the channel of the first vertebral fastener, the first member including a bore configured to receive the flexible member, the bore having a central longitudinal axis;wherein the at least a portion of the first member is positionable into the channel of the first vertebral fastener by translation of the first member in a direction generally transverse to the central longitudinal axis of the bore.
