Influencing factors for postoperative residual low back pain in elderly patients with osteoporotic thoracolumbar vertebral compression fracture and construction of prediction model
Objective To analyze the influencing factors for post-operative residual low back pain in elderly patients with osteoporotic thoracolumbar vertebral compression fracture,and establish a predic-tion model.Methods A total of 85 elderly patients with osteoporotic thoracolumbar compression fracture with postoperative residual low back pain and no residual low back pain were selected from September 2019 to September 2022(the former as the study group and the latter as the control group).Clinical data of the two groups were collected.Univariate analysis and multivariate logistic regression analysis were conducted to identify the influencing factors for postoperative residual low back pain.A prediction model was established,and its predictive performance was analyzed using the receiver operating characteristic(ROC)curve.Results Fascia injury,low T value of bone mineral density,bone cement distribution(type O)and short-term complications were independent risk factors for post-operative residual low back pain,while early rehabilitation intervention and good compliance with rehabilitation intervention were pro-tective factors(P<0.05).The risk prediction model was as follows:Log(P)=2.084×fascia injury+2.187×T value of bone min-eral density+1.793×bone cement distribution+1.796×short-term complications-3.099×early rehabilitation intervention-3.734×compliance with rehabilitation intervention-27.052.The area under the ROC curve of this model to predict postoperative residual low back pain in elderly patients with osteoporotic thoracolumbar vertebral compression fracture was 0.888(95%CI:0.837~0.938,P<0.05).The sensitivity and specificity of the model were the best when its threshold value was 16.98,which was 0.867 and 0.864,respectively.Hosmer-Lemeshow test for this model showed no statistically significant difference,with good coincidence.Con-clusion Fascia injury,low T value of bone mineral density,bone cement distribution(type O)and short-term complications are inde-pendent risk factors for postoperative residual low back pain in elderly patients with osteoporotic thoracolumbar vertebral compression fracture.Early rehabilitation intervention and good compliance with rehabilitation intervention are protective factors.A prediction model can be established based on these factors,and corresponding intervention measures should be carried out to alleviate pain.
