Abstract 【Objective】To explore the clinical effect of the percutaneous pedicle screw internal fixation in the treatment of single-vertebral type A3 thoracolumbar fractures. 【Methods】From August 2016 to August 2018, a total of 40 patients with single-vertebral type A3 thoracolumbar fracture admitted in the First People's Hospital of Chenzhou were analyzed. They were divided into the observation group and the control group, with 20 cases in each group. Patients in the observation group received percutaneous pedicle screw internal fixation, while patients in the control group received posterior open surgery. The perioperative indexes, preoperative and postoperative VAS scores, Cobb's angle, and the percentage of the anterior edge of the vertebral body were compared between the two groups.【Results】Blood loss was (101.0±11.2) mL in the observation group and (360±29.3) mL in the control group ( P <0.01). Operation time was (96.0±9.8) min in the observation group and (133.6±9.5) min in the control group ( P <0.01). Incision length was (7.2±0.5) cm in the observation group and (14.3±1.3) cm in the control group ( P <0.01). Postoperative effusion was (15.0±3.28) mL in the observation group and (144.5±21.6)mL in the control group ( P <0.01). Postoperative hospital stay was (9.0±0.86) d in the observation group A and (16.3±1.0) d in the control group. The amount of blood loss, operation time, incision length, postoperative exudation, and hospital stay in the observation group were less than those in the control group, and the difference was statistically significant ( P <0.05). There was no significant difference in the preoperative VAS scores between the two groups (all P >0.05). VAS scores at 1 week, 1 month, 3 months, and 6 months after surgery in the observation group had significant lower than those in the control group; the difference was statistically significant ( P <0.05).There was no significant difference between the two groups in the preoperative Cobb angle and anterior height ratio of the injured vertebrae ( P >0.05). There were no significant differences in the Cobb angle and the anterior height of vertebral body at admitting to hospital, postoperative one month and one year after operation ( P >0.05). 【Conclusion】Minimally invasive percutaneous pedicle internal screw fixation without decompression pressure in the treatment of single-vertebral type A3 thoracolumbar fractures has better clinical curative effect than open surgery. It also provides less bleeding, shorter hospitalization time, a small incision, less postoperative pain and quicker recovery.
