Abstract Objective: To explore the effect of single, bilateral nail and trans-nail on the efficacy and complications of type A1 thoracolumbar fracture. Methods: A total of 129 patients with A1 thoracolumbar fractures admitted from May 2019 to May 2020 were selected as the subjects who were simply randomly divided into group A, B and C, 43 cases in each. Patients in group A were treated with trans-vertebral screw placement, patients in group B with trans-vertebral screw placement on one side, patients in group C with trans-vertebral screw placement on both sides. The three groups were followed up for 1 year to compare the differences in surgical indexes, efficacy and complication. Results: During the follow-up, all patients had no serious complications such as vascular, nerve and visceral injuries during the operation. The amount of intraoperative blood loss and duration of operation in group A were lower than those in group B and C (P<0.05); walking time, full weight bearing time, hospital stay, ratio loss rate of anterior edge height and sagittal Cobb Angle loss rate of injured vertebrae were higher than those of B and C groups(P<0.05), but there was no significant difference between group B and group C (P>0.05).Repeated measures of ANOVA showed that 1 week and 1 year after surgery, Cobb Angle of sagittal position, high compression rate of anterior edge of injured vertebrae and Oswestry dysfunction score of injured vertebrae in group A were all higher than those in group B and C, and the differences were statistically significant(P>0.05). Conclusion: The treatment of injured vertebral nail in patients with A1 thoracic and lumbar fracture is better than the trans-injured vertebral nail, which can effectively prevent the late vertebral height loss and posterior protrusion deformity, and improve the prognosis of patients. Moreover, there is no obvious difference between single vertebra and bilateral nailing, which can be selected according to the patient's condition.

Key words： A1 type thoracolumbar fractures Unilateral fixation of injured vertebrae Bilateral fixation of injured vertebrae Trans-injury nailing Curative effect Prognosis
