皮下腰椎指数作为经皮椎体球囊后凸成形术后腰背疼痛缓解不佳的风险因素研究
Subcutaneous lumbar spine index as a risk factor for poor relief of low back pain after percutaneous vertebral balloon kyphoplasty
摘要
Abstract
Objective:To analyze whether the subcutaneous lumbar spine index(SLSI)is a risk factor for low back pain(LBP)in patients with osteoporotic vertebral compression fractures(OVCF)following percutaneous balloon kyphoplasty(PKP).Methods:A total of 80 OVCF patients were selected.Based on the Visual Analogue Scale(VAS)score 1 month post-PKP,patients were divided into two groups:LBP group(VAS≥4,n=35)and non-LBP group(VAS<4,n=45).General clinical data,preoperative and intraoperative information were compared between the two groups,and the alleviation of low back pain and functional improvement were assessed.Logistic regression analysis was performed to evaluate risk factors for LBP,and ROC curves were used to assess the predictive value of SLSI for LBP.Results:The LBP group had a significantly longer hospital stay compared to the non-LBP group(P<0.05).There was a statistically significant difference in the distribution of bone cement between the two groups(P<0.05),with the LBP group having less bilateral distribution of bone cement.There were no statistically significant differences in VAS and Oswestry Disability Index(ODI)scores preoperatively and at three days postoperatively(P>0.05).However,the LBP group had higher VAS and ODI scores than the non-LBP group at 3,6,and 12 months postoperatively(P<0.05).Univariate and multivariate Logistic regression analyses showed that SLSI was significantly higher in the LBP group compared to the non-LBP group(P<0.05),indicating it as a risk factor for LBP after PKP.ROC curve analysis indicated that the area under the curve(AUC)for SLSI was 0.769(95%CI:0.667～0.871),with a cutoff value of 0.765 determined by the Youden index(sensitivity:88.6%,specificity:57.8%).Conclusion:A higher SLSI is associated with LBP following PKP.It is recommended that SLSI assessment be performed prior to PKP in OVCF patients as a potential effective predictor for postoperative LBP.关键词
