ObjectiveBalloon kyphoplasty (BKP) is an effective procedure for osteoporotic vertebral compression fractures; however, there is limited data regarding its outcomes in patients aged ≥81 years. This study investigated the treatment outcomes and prognostic factors for BKP in this age group.MethodsA retrospective analysis was conducted on 115 patients with osteoporotic vertebral compression fracture undergoing single-level BKP after failed conservative treatment, classified into the <81 years (n=70) and ≥81 years (n=45) groups. Surgical results were evaluated as good outcomes (independent indoors 1 year postoperatively) and poor outcomes, followed by univariate and multivariate analyses to determine prognostic factors correlating with these outcomes.Results And ConclusionThe majority of patients (<81 years: 85.7%; ≥81 years: 73.3%) had a good degree of independence at 1 year postoperatively, which was comparable in both groups. Further analysis of patients aged ≥81 years showed that longer duration from onset to surgery, more subsequent vertebral fractures, and lower preoperative body mass index were correlated with poorer outcomes postoperatively, and low body mass index, time from onset to surgery, and female sex were independent risk factors for these outcomes (area under the receiver operating characteristics curve: 0.91).Copyright © 2024 Elsevier Inc.
