Clinical effects of posterior long-segment percutaneous pedicle screw fixation on patients with ankylosing spondylitis complicated with thoracolumbar fractures

【Objective】To observe the clinical effects of posterior long-segment percutaneous pedicle screw fixation on patients with ankylosing spondylitis(AS)complicated with thoracolumbar fractures.【Methods】A retrospective analysis was performed on clinical data of patients with AS and thoracolumbar fractures in our hospital from June 2017 to December 2018 who received posterior long-segment conventional incision internal fixation(control group,n=65)and or who underwent posterior longsegment percutaneous pedicle screw fixation(research group,n=54).The intraoperative and postoperative indexes,pain level(VAS score)before surgery,1 week after surgery and 6 months after surgery,anterior height of vertebral body and Cobb angle of injured vertebrae before surgery,6 months after surgery and 12 months after surgery and recovery of lumbar back function(ODI index)before surgery and 12 months after surgery were compared between the two groups,and the occurrence of complications were recorded within 6 months after surgery.【Results】Six months after surgery,the excellent and good rates of the two groups were 92.59%and 90.77%respectively(P>0.05).The intraoperative blood loss,operative time and hospital stay in study group were significantly lower than those in control group(P<0.05).Before surgery,1 week after surgery and 6 months after surgery,there was a significant difference in the VAS score in the two groups at each time point(P<0.05),and the VAS score in study group at each time point after surgery was lower than that in control group(P<0.05).Before surgery,6 months after surgery and 12 months after surgery,there were significant differences in the anterior height of vertebral body and the kyphosis Cobb angle in the two groups at each time point(P<0.05),but there were no significant differences in the above indexes at each time point after surgery between the two groups(P>0.05).Before surgery,6 months after surgery and 12 months after surgery,there was a significant difference in the ODI index in the two groups(P<0.05),and the ODI index in study group at each time point after surgery was lower than that in control group(P<0.05).Within 6 months after surgery,the incidence rates of complications in study group were significantly lower than those in control group(P<0.05).【Conclusion】For patients with ankylosing spondylitis and thoracolumbar fractures,posterior long-segment percutaneous pedicle screw fixation has a significant treatment effect,and it can not only shorten the operative time and hospital stay and reduce intraoperative blood loss,but also effectively reduce postoperative pain,promote the recovery of lumbar back function and lower postoperative complications,and it has good application value.
