Abstract:【Objective】 To investigate the influencing factors of spinal canal decompression for thoracolumbar burst fractures. 【Methods】A total of 83 patients with thoracolumbar burst fractures treated in our hospital was selected as the research object. According to whether the ratio of the anterior posterior diameter of the spinal canal to the anterior posterior diameter of the adjacent spinal canal was ≥ 90%, they were divided into 57 cases in the good decompression group and 26 cases in the poor decompression group. The age, sex, body mass index (BMI), cause of injury, injury segment, AO classification, Asia classification (Grade A~E), time interval from injury to operation, bone turnover angle, bone displacement distance and surgical approach were compared between the two groups; Logistic regression analysis was used to explore the relationship between the displacement distance of posterior upper edge fracture block and the effect of spinal canal decompression. 【Results】The proportion of patients with Asia Grade A~B and anterior surgery in the good decompression group was higher than that in the poor decompression group (P<0.05); There was no significant difference in age, sex, body mass index (BMI), cause of injury, injury segment, AO classification and time interval from injury to operation between the two groups (P>0.05); The preoperative bone turnover angle and bone displacement distance of patients in the good decompression group were lower than those in the poor decompression group (P<0.05); Logistic regression analysis showed that the increase of preoperative bone mass displacement distance, the high preoperative Asia Grade (C~E Grade) and the use of posterior surgery were the independent risk factors for the poor effect of postoperative spinal canal decompression (P<0.05). 【Conclusion】Patients with thoracolumbar burst fractures have higher preoperative Asia grade, posterior surgery and increased displacement distance of the posterior upper edge of the vertebral body are independent risk factors for poor effect of postoperative spinal canal decompression.
