    ObjectiveThis study aimed to evaluate preoperative and perioperative predictors associated with persistent low back pain (LBP) following lumbar fusion in patients aged >75 years.MethodsThis single-center retrospective study examined 310 patients aged >75 years who underwent lumbar fusion for lumbar degenerative disease (104 males, 206 females; mean age, 79 [75-90] years). The visual analog scale (VAS) score for LBP was examined preoperatively and 2-year postoperatively. The persistent LBP group comprised patients with a 2-year postoperative LBP-VAS score ≥3. The demographic and preoperative radiographic parameters were also reviewed. A multivariate stepwise logistic regression analysis was performed of variables with values of P < 0.2 on the univariate analysis.ResultsNinety-nine patients (32%) experienced persistent postoperative LBP. Multivariate logistic regression analysis revealed that age <82 years, history of previous lumbar decompression, and greater preoperative VAS score for LBP were associated with greater postoperative persistent LBP after lumbar fusion, whereas other factors, such as gender, body mass index, osteoporosis, diabetes mellitus, depression, symptom duration, operative time, estimated blood loss, and spinopelvic sagittal parameters, were not.ConclusionsThis study showed that a relatively younger age, history of preoperative lumbar decompression, and greater preoperative VAS score for LBP were preoperative predictors of postoperative persistent LBP following lumbar fusion in elderly patients. In contrast, preoperative spinopelvic sagittal parameters were not associated with persistent postoperative LBP. Although lumbar fusion is expected to improve LBP, surgeons should pay attention to age, surgical history, and preoperative back pain intensity.Copyright © 2024 Elsevier Inc. All rights reserved.
