INTRODUCTION; The spinal trauma is one of the leading problems in modern era where the individuals are more at risk due to high energy trauma. Thoracolumbar spinal segment is the 2ndmost commonly involved segment after the cervical segment in spinal injuries. About 35 to 60% of all spinal injuries occurring between T12 and L2 . The fractures at thoracolumbar level have associated neurological injury in 15 to 20% patients AIM OF THE STUDY; The aim of this study is to study the efficacy of pedicular screw and rod fixation system in achieving stability and clinical , neurological and radiological outcome MATERIALS AND METHODS; In all, a total of 40 cases were evaluated and assessed during the study period . The study was conducted in the Department of Orthopaedics, GVMCH villupuram. Pre operative x–rays CT,MRI were done and neurological status recorded in all patients. The clinical outcome was measured with Denis pain scale and Denis work scale. Neurological status was assessed with ASIA scale. RESULTS; In our study the clinical outcome was good. Most of the patients returned to their previous job and had a considerable reduction in pain.90% of patients had an improvement in their neurological status. There was a decrease in the regional kyphotic deformity and an increase in anterior vertebral height during the follow up , and four patient had superficial wound infection. CONCLUSION; Instrumented posterior stabilization provides less surgical exposure, correction of deformity and better stabilization of fractures
