Long-term results of posterior anchorage of subaxial vertebra in acute unstable trauma

Abstract

Aim: to study long-term results of posterior anchorage of subaxial vertebra in acute trauma. Material and Methods. We conducted an analysis of long-term results of posterior anchorage of subaxial vertebra in 17 patients with acute unstable trauma which had undergone complex clinical neurological and instrumental investigation, surgical treatment performed from dorsal approach, and the estimation of long-term results in preoperative period. Results. The obtained data indicate the method of transarticular anchorage to be effective and safe and not to have any negative effect on biomechanical properties of cervical spine in the long-term postoperative period. Conclusion. The use of posterior anchorage in acute unstable trauma is most reasonable in subaxial injuries accompagnied by the deformities of medial and posterior spinal columns.
