Abstract Objective: To explore the clinical efficacy of posterior transforaminal pedicle screw fixation and conventional open pedicle screw fixation on thoracolumbar fracture-dislocation injury. Methods: A total of 100 patients with thoracolumbar fracture-dislocation injury who underwent elective surgery were divided into observation group(posterior transforaminal pedicle screw fixation,n=45) and control group(traditional open pedicle screw fixation, n=55) according to the surgical procedures. The operation conditions and pain degree, orthopedic imaging indexes changes and Oswestry dysfunction index score (ODI) before operation, at 24h after operation and at the last follow-up were recorded and compared between the two groups. Results: There was no significant difference in the operative time between the two groups (P>0.05). The intraoperative blood loss and postoperative drainage volume in observation group were significantly less than those in control group, and the hospital stay was significantly shorter than that in control group (P<0.05). The VAS scores in observation group were significantly lower than those in control group at 24h after operation and at the last follow-up(P<0.05).There were no statistical differences in the orthopedic imaging indexes between the two groups before operation and at the last follow-up (P>0.05). At the last follow-up, the change range of ODI score in the observation group was larger than that in the traditional group (P<0.05). Conclusion: Posterior transmuscular pedicle screw fixation has less bleeding and less trauma, which can reduce incision pain and promote functional recovery.
