MRI-STIR黑色信号线对骨质疏松性椎体压缩骨折患者PVP疗效的预测价值
Predictive Value of MRI-STIR Black Signal Line for PVP Efficacy in Patients with Osteoporotic Vertebral Compression Fractures
摘要
Abstract
Objective:To Explore the predictive value of black signal lines of short wave reversal recovery sequence(STIR)in magnetic resonance imaging for the efficacy of vertebral augmentation(PVP)in patients with osteoporotic vertebral compression fractures.Methods:The study was conducted from February 2022 to December 2023,including 123 patients with osteoporotic vertebral compression fractures treated in our hospital,all of whom underwent MRI-STIR and QCT and underwent PVP after diagnosis.Patients were divided into two groups based on the black signal line in MRI-STIR:those with signal(n=50)and no signal(n=73)and followed for 6 months.Results:There was a statistically significant difference in the distribution of vertebral lesions,signal changes,paraspinal mass signal changes,and adjacent vertebral body signal changes between the two groups(P<0.05).There was no statistically significant difference in the injection volume of bone cement between the two groups(P>0.05);the bone density of patients in the signal group was lower than that in the non signal group,and the incidence of bone cement leakage and poor diffusion were higher than that in the non signal group,with statistically significant differences between the groups(P<0.05).Before surgery and 3 months after surgery,there was no statistically significant difference in Visual Analog Scale(VAS)scores between the two groups(P>0.05);on postoperative days 3 and 7,the VAS scores in the signal group were higher than those in the non signal group,and the difference were statistically significant(P<0.05).At 3,7 days,and 3 months after surgery,the Oswestry Disability Index scores of patients in the signal group were higher than those in the non signal group,and the difference were statistically significant(P<0.05).There was no statistically significant difference in the height ratio and Cobb angle of the injured vertebrae between the two groups before Surgery and 7 days,and 3 months after surgery(P>0.05).Six months after surgery,the incidence of recurrent fractures,Cobb angle changes,and vertebral height loss in the signal group was higher than that in the non signal group,and the differences were statistically significant(P<0.05).Conclusion:Patients with a dark signal line in MRI-STIR had lower bone density,higher rates of complications in PVP treatment,and worse short-term pain and disability scores,with a higher risk of structural changes and re-fracture in long-term follow-up.Thus,the dark signal line in MRI-STIR can serve as an important indicator for assessing the efficacy and risks in patients with vertebral compression fractures.关键词
