Comparative Study of Radioclinical Outcomes of Short-Segment Pedicle Fixation Versus Long-Segment Pedicle Screw Fixation In Unstable Thoracolumbar Burst Fracture
Keywords:
Anterior vertebral body height, posterior vertebral body height and ratio of AVBH/PVBH.Abstract
Background: This study is to compare the traditional long segment fixation and the short segment fixation analyzing the correction of deformity, maintenance of the correction,functional and neurological outcomes and prevention of fixation failure in thoracolumbar burst fracture.
Methods: This study was conducted in 50 consecutive cases of short segment fixation and long segment fixation and comparison by using ASIA impairment scale ,cobbs angle, anterior vertebral body height (AVBH), Posterior vertebral body height PVBH), and ratio of AVBH and PVBH.
Results: Functional and neurological outcomes on basis of ASIA scoring and outcome in our study was similar in both group.Long segment instrumentation prolonged the operative time and increased the amount of blood loss significantly as compare to short segment fixation. Less loss of kyphosis correction was noticed in long segment as compare to short segment in thoracolubar burst fracture. Comparison of anterior vertebral body height, posterior vertebral body and ratio of AVBH/PVBH between short and long segment was statistically not significant .
Conclusion: Study comparing short segment versus long segment fixation in thoracolumbar burst fractures, demonstrated that long segment instrumentation is an effective way to correction of local kyphosis in thoracolumbar burst fractures.
