Objective: To evaluate the efficacy of percutaneous posterior pedicle screw system in asymptomatic single segment A3 thoracolumbar burst fractures. Methods: From January 2018 to May 2021, 25 patients with asymptomatic single-segment A3 thoracolumbar burst fractures without neurological symptoms were treated. All patients were treated with a simple percutaneous posterior pedicle screw system to perform a reduction of the fracture block by the same group of physicians. CT examinations were performed before and after surgery, and the fracture reduction and spinal canal diameter recovery were followed up, and the clinical data were retrospectively analyzed. Results: Postoperative CT scan was performed on 25 patients. The results showed that the posterior margin of the thoracolumbar spine was well restored, the height of the vertebral body and the diameter of the spinal canal were basically restored, and the space occupied by the spinal canal disappeared. On the third day after surgery, the patients had a postoperative cobb angle (6.16°±3.43°), anterior edge compression ratio of vertebral body (5.55%±2.61%), and vertebral body translation rate (6.81%±3.07%)Compared with the preoperative cobb angle (14.5°±5.91°), the anterior edge compression ratio of vertebral body (30.96% ±5.80%), the vertebral body translation rate (21.44% ±7.29%), the spinal canal mass (35.75% ±12.46%), and the VAS score (6.52±1.42) were significantly improved. The difference was statistically significant (P <0.05). All patients were followed up for 22 to 30 months, with an average of 26.44±2.02 months. The postoperative cobb angle, anterior margin compression ratio, vertebral body translation rate, and spinal canal occupancy rate were not significantly different after surgery. The difference was not statistically significant (P>0.05). Conclusion: Single segment A3 thoracolumbar burst fracture without neurological symptoms treated with percutaneous posterior pedicle screw system, no open surgery, has certain effectiveness and safety, This surgical method can be combined with clinical indications for scientific and rational application to reduce surgical trauma.
