ABSTRACT

In thoracolumbar burst fractures, short segment pedicular fixation is an often method which provides stable fixation with less segment involvement. Despite of this, it is found to be inadequate secure the reduction and cause increase of implant failure risk. In this study we aim to determine the effect of long segment posterior fixation in correction and preservation of deformity caused by vertebral fracture. We evaluate patients who had long segment posterior fusion surgery for single level Denis type B patlama fracture retrospectively. The radiologic evaluation of patients done with anterior corpus height loss (ACHL) and local kyphosis angle (LKA) preoperatively, postoperatively and late postoperative. All implant systems were the same and by reason of no patients has neurolojic deficiency, no laminectomies or decompresions performed. Patients evaluated clinically with Linkert questionaire. The period between the accidents and surgeries was 21 hours. Average follow-up time was 42 months. ACHL decresed from 40.55 % to 10.42 % after surgery, but increased to 17,41° at follow up visit. LKA was 16,41° preoperatively and 4.02° in followup. Pain and function scores are good in follow-up. Consequently we believe that long segment posteior fixation should be the prefered choice in treatment of single level Dennis type B burst fractures
