Radiological and Functional Outcome of Short Segment Posterior Stabilization with Intermediate Pedicle Screw in Single Level Thoracolumbar Burst Fractures: A Prospective Study (original) (raw)

Background: Thoracolumbar junction (D11-L2) is very prone for injury because of its location between rigid kyphotic thoracic spine and mobile lordotic lumbar spine. Method: 35 patients treated with short segment pedicle screw fixation with intermediate screw. Clinical (oswestry disability index) and radiological (local kyphotic angle and beck’s index) parameters were used. Results: Most of our patients were male (28 male), 7 female (25.71%)]. Most common involved level L1 (80%) and D12 (25%).Mean preop ODI is 92.037 which decreased to 28.673. Mean preop local kyphotic angle is 15.028° which was corrected to 4.057° with correction loss of 0.657 at final follow-up. Mean preop beck’s index was 0.543 which was corrected to was 0.864 with correction loss of 0.024 at final follow-up. Conclusion: Reinforcement with intermediate screw for a single thoracolumbar burst fracture enhanced the stability. It was faciliative to correction of kyphosis with maintenance of the reduction effects with ...
