Abstract

An anchoring member is provided which comprises a shaft 2 to be fastened to a bone and a head 3 for connection with a rod 10, the head having a substantially U-shaped cross-section and being connected with the shaft 2 at the base 5 thereof, the head further comprising two free legs 6, 7 defining a channel 4 for receiving the rod 10. The free legs 6, 7 are provided with an internal thread 8 extending in direction of the legs. A fastening member 11 and a member 12 embracing the legs at the outside thereof are provided. In order to allow not only straight rods, but also curved rods to be received and thus to allow an individual adaptation to the conditions of the spinal column to be treated the free legs have an external thread 9 and the member 12 has an internal thread cooperating therewith. The fastening member 11 comprises a thread cooperating with the internal thread 8 to allow the fastening member to be screwed in.
