    ObjectiveTo retrospectively analyze prognostic factors in osteoporotic patients who treated with percutaneous vertebroplasty for refracture after vertebral augmentation.MethodsA retrospective analysis was performed of 61 patients with refractures after vertebral augmentation who received percutaneous vertebroplasty treatment again from January 2019 to December 2021. Based on the presence of back pain at the last follow-up, 17 patients were placed in the pain group, and 44 patients were placed in the pain-free group. The following covariates were reviewed: age; bone mineral density; bone cement dosage; bone cement leakage; body mass index; and rate of anterior vertebral height (AVH) loss in the target before surgery, 1 week after surgery, and at last follow-up. Patients were assessed using visual analogue scale score and Oswestry Disability Index.ResultsBinary logistic regression analysis revealed that the rate of AVH loss after surgery was associated with postoperative back pain. According to the receiver operating characteristic curve analysis, the area under the curve of AVH loss rate at 1 week after surgery was 0.6845, and the cutoff value was 0.18; the area under the curve of AVH loss rate at the last follow-up was 0.7306, and the cutoff value was 0.2815. Kaplan-Meier survival analysis showed that patients with lower AVH loss rates had lower incidence of postoperative back pain and better prognosis.ConclusionsOccurrence of postoperative back pain was strongly associated with AVH loss after surgery. Patients with a lower rate of AVH loss had a lower incidence of postoperative back pain and a better prognosis.Copyright © 2022. Published by Elsevier Inc.
