ObjectivesTo explore the risk factors of residual back pain after percutaneous vertebroplasty (PVP) in patients with osteoporotic vertebral compression fracture (OVCF).MethodsWe retrospectively reviewed the records of 675 patients with OVCF treated with PVP from January 2015 to January 2020. Postoperative back pain intensity was assessed by the VAS score. Residual back pain was defined as the presence of postoperative moderate-severe pain (average VAS score≥4), and the variables included patient characteristics, baseline symptoms, imaging data and operation-related factors. Risk factors were identified with univariate and multivariate logistic regression analysis.ResultsResidual back pain occurred in 46 of the 675 patients included in the study, with an incidence rate of 6.8%. Multivariate logistic regression analysis showed that low Pre-BMD (OR = 3.576, P = 0.041), multiple vertebral fractures (OR = 2.795, P = 0.026), posterior fascia injury (OR = 4.083, P = 0.032), cement diffusion volume rate <0.2 (OR = 3.507, P = 0.013), facet joint violation (OR = 11.204, P < 0.001), and depression (OR = 3.562, P = 0.035) were positively correlated with residual back pain after PVP.ConclusionsLow pre-BMD (pre-bone mineral density), multiple vertebral fractures, posterior fascia injury, cement diffusion volume rate <0.2, facet joint violation and depression were the independent risk factors of residual back pain after PVP.Copyright © 2023 Elsevier Inc.
