Background:.The Thoracolumbar Injury Classification and Severity Score (TLICS) was developed to improve injury classification and guide surgical decision making, yet validation remains necessary. This study evaluates the functional ,clinical and radiological outcome of patients with thoracolumbar spine trauma (TLST) treated according to the TLICS. Aim of the work:To validate the efficacy of Thoracolumbar injury classification and severity score (TLICS) in orthopaedic emergency department at sohag university hospitals. Patients and methods:The TLICS was prospectively applied to a consecutive series of patients (30 cases) treated for TLST between October 2016 and October 2017. Patients with a TLICS score more than 4 points were surgically treated, whereas patients with a TLICS score of less than 4 points were conservatively managed.Those with a score of equal 4 ,group were managed conservatively and the other were operated.The primary outcome was the American Spinal Injury Association Impairment Scale (AIS)(1). Results:The decision taken according to TLICS either conservative if the final score 4. Conservative treatment in the form of rest and dorsolumbosacral brace .Operative in form of posterior fixation with or without decompression .Transpedicular fixation and decompression was needed in 10 cases (33.33%) because they were suffering from neurological insult.The mean age was 34years.There were a marked improvement in angle of kyphosis , vertebral height loss and Oswestry disability index .No patient had neurological worsening during the follow-up. Conclusion:.Thoracolumnar injury and severity score is valid and safe for management of thoracolumbar fractures and has good reliability.
