Effect of decompression,reduction and fixation through medial pedicle approach in treatment of thoracolumbar vertebral burst fracture and factors influencing outcome of postoperative spinal injury
Objective To explore the curative effect of decompression,reduction and fixation through medial pedicle ap-proach on thoracolumbar vertebral burst fracture,and factors influencing the outcome of postoperative spinal injury.Methods This study included 102 patients with thoracolumbar vertebral burst fracture treated with decompression,re-duction and fixation through medial pedicle approach in our Hospital.The anterior vertebral height loss rate,Cobb an-gle,spinal canal invasion rate and the outcome of spinal injury were observed.The high-risk factors for the outcome of postoperative spinal injury were analyzed.Results The anterior vertebral height loss rate,Cobb angle and spinal canal invasion rate at 1 year after operation were lower/smaller than those before operation(P＜0.05).The grade of spinal injury after operation was better than that before operation(P＜0.05).Univariate analysis showed that preoperative in-jury,hormone use within 8h after injury and spinal canal invasion rate were related to postoperative spinal injury(P＜0.05).Preoperative injury,hormone use within 8h after injury and spinal canal invasion rate were high-risk fac-tors for the outcome of postoperative spinal injury(P＜0.05).Conclusion Decompression,reduction and fixation through medial pedicle approach is effective in the treatment of thoracolumbar vertebral burst fracture,which can effec-tively restore the height of the injured vertebra,and improve spinal nerve function.Spinal canal invasion rate,preopera-tive injury degree,and hormone use within 8h after injury are main factors influencing the outcome of postoperative spi-nal nerve injury.
