  • Patent number: 8764802
    Abstract: A pedicle screw for intervertebral support elements consists of a shaft and a head comprising at least two parts. The head is formed as a securing means for at least one support element. Each support element consists of a piece of a cable-like band and a cylindrical support body with an axial lumen containing the band. The band is securable outside end surfaces of the support body in the head. The head is formed with a contact surface 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 of the head, which is firmly connected to the shaft at the one end of the latter, contains a base groove which is oriented transversally to the shaft and into which the part of the band to be secured or a connecting piece which contains the band can be introduced during the securing of the support element by means of a translatory movement in the direction of the shaft and fixed there.
