BackgroundAlthough many risk factors for residual pain following percutaneous vertebroplasty or kyphoplasty (PVP or PKP) have been reported in many studies, research methods and cohorts differ greatly. A previous meta-analysis identified patient- and operation-specific risk factors for residual pain. This study aimed to examine the available data and identify significant risk factors for residual pain after PVP or PKP.MethodsPubMed, EMBASE, Web of Science, and the Chinese Wanfang Database were searched for relevant research in English and Chinese, and full-text publications including patients with and without residual pain were compared. Only studies presenting odds ratios from multivariate analysis of residual pain data were considered. To evaluate the impact of the results of the selected articles, Review Manager 5.4 was used.ResultsTwelve publications including a total of 3120 patients met the requirements. The meta-analysis examined 10 factors associated with residual pain and categorized them as either patient- or operation-associated factors. Thoracolumbar fascia injury, intravertebral vacuum cleft, depression, and number of fractured vertebrae were all significant patient-associated parameters for residual pain. Significant operation-associated risk factors included bone cement distribution and intraoperative facet joint injury.ConclusionsIn this meta-analysis, we identified several significant risk factors for residual pain after PVP or PKP. These findings may be helpful for patient counseling and surgical planning.Copyright © 2024 Elsevier Inc. All rights reserved.
