Abstract
It is known to use pedicle screws and connectors to treat deformities in a spinal column. However, there are cases when screws must be installed in certain positions relative to each other as otherwise the connector may not fit correctly between them. A spinal anchoring element system is therefore provided, comprising a guide tool 60 for aligning a screw-path forming instrument 90 for use in forming a screw-path in a vertebra 10 for the subsequent installation of a pedicle screw 20, the guide tool comprising a guide tool stem 80 and a screw-path forming instrument receiving section 70, the guide tool stem and the screw-path forming instrument receiving section being immovable relative to one another.

A spinal anchoring element system, comprising:
- a) a screw-path forming instrument for use in forming a screw-path in a vertebra for the subsequent installation of a pedicle screw,
- b) a guide tool for aligning the screw-path forming instrument, wherein the guide tool comprises a guide tool stem and a screw-path forming instrument receiving section, the guide tool stem and the screw-path forming instrument receiving section being immovable relative to one another, and
- c) a screw-path forming instrument receiving member, the screw-path forming instrument receiving member including attachment means for attaching it to the guide tool, the screw-path forming instrument receiving member including an internal screw thread for receiving the screw-path forming instrument for creating a thread on the inside surface of the screw-path created in the vertebra by the screw-path forming instrument,
- wherein the screw-path forming instrument includes a guide tool mating section for aligning the screw-path forming instrument in relation to the guide tool.
