Abstract

The stabilization systems of a spine by transpedicular screws, laminar and cross hooks are the gold standard of surgical treatment various kinds pathology of a spine, postoperative oligo- or polysegmentar instability.

In 2000 the Institute neurosurgery together with the company INMED developed the new system of polyaxial fixing Coolkeeper F. In 2002 systems Coolkeeper F was further advanced in system Coolkeeper U. The new system was completely universal. This system easy to join with cervical laminar, transpedicular or transarticular fixation system.

 In first spinal clinic of Institute neurosurgery the new transpedicular systems of the mark Coolkeeper F and Coolkeeper U was applied at various pathological conditions requiring transpedicular fixing of thoracic and lumbar part of a spine (48 patients). Traumatic lesions were in 25 patients, spondylosistesis in 9 patients and vertebrae tumors in 14 patients.

We achieved firm stability after operation, that has allowed to carry out early activation of patients. At control ÌRI researches are found out minimal artifacts caused by titanium, that has allowed completely visualized spine, spinal cord, cerebrospinal fluid. At control X-ray, CÒ and ÌRI studies through 3, 6 and 12 months the position polyaxial systems was stable. The systems provided reliable immobilization of the stabilized segments of a spine. Damages of systems, the displacement of screws from vertebral bodies we never have revealed. In one case carried out repeated intervention on lengthening system.

Polyaxial system are useful updating of system transpedicular fixing, is especial in case of multilevel fixing of a spine.
