Effect of manual reduction and indirect decompression on thoracolumbar burst fracture: a comparison study

OBJECTIVE: To evaluate the effect of manual reduction and indirect decompression on thoracolumbar burst fracture. METHODS: Sixty patients with thoracolumbar burst fracture who were hospitalized from January 2018 to October 2019 were selected and divided into an experimental group (33 cases) and control group (27 cases) according to different treatment methods. The experimental group was treated with manual reduction and indirect decompression, while the control group was not treated with manual reduction. The operation time and intraoperative blood loss were recorded. VAS score was used to evaluate the improvement of pain. The anterior height of the injured vertebra, wedge angle of the injured vertebral body, and encroachment ratio of the injured vertebral canal were used to evaluate the spinal canal decompression and fracture reduction. JOA score was used to evaluate the improvement of spinal function. RESULTS: There was no significant difference in operation time and intraoperative blood loss between the two groups. Compared with the control group, the VAS score and the wedge angle of the injured vertebral body of the experimental group 3 days after the operation and the last follow-up were significantly lower than that of the control group, and the difference was statistically significant. The ratio of the anterior height of the injured vertebra of the experimental group 3 days after the operation and the last follow-up was significantly higher than that of the control group, and the difference was statistically significant. The difference of the encroachment ratio of the injured vertebral canal between preoperation and 3 days after operation was significantly higher than that of the control group, and the difference was statistically significant. The bladder function of JOA 3 days after the operation of the experimental group was significantly higher than that of the control group, and the difference was statistically significant. And the rest aspect of JOA on 3 days after the operation and last follow-up of the experimental group has no significant difference compared with the control group. CONCLUSION: Manipulative reduction and indirect decompression can obtain a better clinical effect in the treatment of thoracolumbar burst fractures.
