Abstract:Objective: To study the effects of different internal fixation operations on the spinal stability of A1 thoracolumbar fracture.Methods: A retrospective analysis was conducted on the clinical data of 146 patients with A1 type thoracolumbar fractures treated in our hospital from January 2021 to January 2023. Based on the method of internal fixation surgery, 82 patients who underwent six-screw transpedicular fixation were included in Group A, and 64 patients who underwent four-screw transpedicular fixation were included in Group B. Perioperative indicators, sagittal Cobb angle, vertebral height compression rate, Oswestry Disability Index (ODI), stress indicators, and postoperative complications were compared between the two groups.Results: No significant differences were found between Group A and Group B in terms of intraoperative blood loss (248.49±22.36 mL vs. 244.03±20.71 mL), bed rest duration (4.92±1.24 days vs. 5.03±1.10 days), and hospital stay length (8.35±1.76 days vs. 8.75±1.43 days) (P>0.05). The surgery time was significantly longer in Group A (129.80±17.02 minutes) compared to Group B (122.95±15.63 minutes) (P<0.05). At the T2 time point, the sagittal Cobb angle, vertebral height compression rate, and ODI were significantly lower in Group A than in Group B (P<0.05). There were no significant differences in the levels of prostaglandin E2 (PGE2) and norepinephrine (NE) between the two groups at 24 hours and 3 days postoperatively (P>0.05). The incidence of postoperative complications did not differ significantly between the two groups (χ2=2.598, P=0.107).Conclusion: Although the six-screw transpedicular fixation surgery has a longer duration, it more effectively restores spinal stability and improves functional outcomes in patients with A1 type thoracolumbar fractures.
