Abstract：Objective To evaluate the clinical efficacy of intervertebral and transpedicular short segment fixations in thoracolumbar vertebral fractures. Methods Data of 50 patients with thoracic and lumbar vertebral fractures was retrospectively analyzed,who were treated by short segment fixation in People's Hospital of Bozhou City during Jan.2015 and Jul.2016.Twenty-two patients with thoracolumbar vertebral fractures received intervertebral short segment fixation (control group),and 28 patients with thoracolumbar vertebral fractures received transpedicular short segment fixation (test group).Patients' vertebral height ratio and sagittal Cobb angle were compared before operation,after operation and at 6 months after operation.Also,the operation time and blood loss were compared. Results There was no statistical difference (P<0.05) in vertebral height ratio and sagittal Cobb angle before operation between the two groups (P>0.05),but had difference (P<0.05) when compared with after operation.In regard of time points of after operation and at 6 months after operation,the vertebral height ratio of the test group was higher than the control group [(88.8±10.5)% vs.(85.1±10.1)%,(86.1±10.4)% vs.(80.6±10.4)%],and sagittal Cobb angle was lower than that of the control group[(5.7±3.2)° vs.(6.3±4.7)°,(6.8±3.6)° vs.(12.1±5.6)°],with statistical difference between the two groups (P<0.05).The operative time,blood loss of the test group were higher than those of the control group[(125±20.5)min vs.(100±26.4)min,(252.6±48.4)mL vs.(146.4±50.2)mL],and the differences were statistically significant (P<0.05). Conclusion Transpedicular short segment fixation in thoracolumbar vertebral fractures could effectively correct kyphosis,reconstrcuct vertebral height and postoperative recovery,and it has greater surgical trauma than the intervertebral short segment fixation.
