Abstract:Objective To compare the clinical efficacy of posterior open and percutaneous pedicle screw fixation in the treatment of single segment asymptomatic thoracolumbar vertebral body fractures.Methods From August 2018 to November 2020,32 patients with thoracolumbar vertebral body fractures including 18 males and 14 females with an average age of (53.56±9.48)were randomly divided into open group(n=16)and percutaneous group(n=16).The percutaneous group was treated with minimally invasive percutaneous pedicle screw fixation,and the open group was treated with open pedicle screw fixation.The operation time,intraoperative blood loss,postoperative hospital stay,incision length,visual analogue score(VAS) before and after surgery,the ratio of anterior and posterior vertebral height(%) and kyphosis Cobb angle at the last follow-up were compared between the two groups.Results All patients were followed up for 6 ~ 12 months,with an average follow-up of (9.20±2.14)months.There were no significant differences in baseline data,ratio of anterior and posterior vertebral height(%) and kyphosis Cobb angle between the two groups(P>0.05).The VAS score of the percutaneous group was slightly higher than that of the open group on the first day after operation,but the difference was not statistically significant(P>0.05).The ratio of anterior and posterior vertebral height(%)and kyphosis Cobb angle in two groups were significantly improved postoperation(P<0.05).The minimally invasive group had less intraoperative blood loss,shorter operation time,shorter postoperative hospital stay,shorter incision length,lower VAS score on the third day after operation and the differences were statistically significant compared with the open group(P<0.05).Conclusion Minimally invasive percutaneous pedicle screw fixation and open pedicle screw fixation in the treatment of thoracolumbar vertebral body fractures have the same curative effect,but the percutaneous group has the advantages of less blood loss,shorter operation time and postoperative hospital stay,less trauma and lower VAS.
