Analysis of results of reduction of kiphotic deformation by minimally invasive transpedicular stabilization in patients with traumatic compression fractures of thoracolumbar localization

Abstract

OBJECTIVE. Minimally invasive correction of posttraumatic deformation and stabilization of damaged segment are important in treatment and prevention of complications after traumatic compression fractures of the vertebral bodies. MATERIAL AND METHODS. Retrospective study was made in 25 patients with A2-A3 fractures of the vertebral bodies at the period from 2014 to 2015. The patients underwent transcutaneous transpedicular fixation. The research was based on prospectively collected data. The authors evaluated the dynamics of kyphotic deformation of the spine (Cobb angle, sagittal index) before and after operation. RESULTS. The elimination of thoracic and lumbar spine traumatic deformation resulted in decrease of Cobb angle from 42º (39…44º) and 17º (8…24º) to 21º (20..23º) and 9º (5…14º), respectively (p < 0,01 and p < 0,03). There wasn’t noted any significant decrease of reduction angle (p =0,38 and p = 0,46). CONCLUSIONS. Percutaneous transpedicular fixation is the effective minimally invasive method of treatment for patients with A2-A3 traumatic compression fractures of the vertebral bodies.
