Posterior Spinal Stabilisation Using Pedicle Screw fixation in Thoracolumbar Vertebral Fractures

Abstract

Introduction: Pedicle screw provide good control over the three spinal columns of spine and their usage has been diversified from lumbar spine to thoracolumbar and thoracic spine. We evaluated the early results of posterior spinal stabilisation using pedicle screw fixation in twenty patients with thoracolumbar vertebral fractures. Material and Methods: Posterior spinal stabilisation using Pedicle screw construct was done along with laminectomy whenever needed in twenty patients with thoracolumbar vertebral fractures . Patients were followed up for minimum six months. Results: Mean age of the study group was 34.8 years. The most common mode of injury was fall from height (60%). Preoperatively 85% (n=17) of the patient had useless paraplegia (Frankel Grade C and below) whereas 15% (n=3) of the patients had useful paraplegia i.e. Frankel Grade D & E. Post-operatively 60% (n=12) patients had useful paraplegia (Frankel D & E), whereas 40% (n=8) patients had useless paraplegia (Frankel Grade C & below). 30% of the patients were able to return to their previous work or physically challenging job, 25% were able to return to previous employment to heavy labor with some restriction, 35% of the patients were unable to return to their previous employment but worked for full time in their new employment and 10% of the patients were unable to return to their work.Conclusion: Posterior pedicular screws fixation is a effective option for treatment of single-level traumatic thoracolumbar fracture, provided satisfactory functional outcome with preservation of cobbs angle and vertebral height postoperatively without loss of more motion segments.
