BackgroundRecently, the incidence of pyogenic vertebral osteomyelitis with spinal epidural abscess (SEA) has increased. However, the most appropriate surgical management remains debatable, especially for older patients. This study aimed to compare the clinical course in older patients aged between 65 and 79 years and those 80 years or older undergoing surgery for SEA.MethodsData on patient demographics, surgical characteristics, complications, hospital clinical course, and 90-day mortality of patients diagnosed with pyogenic vertebral osteomyelitis and SEA between September 2005 and December 2021 were collected. Comorbidities were assessed using the age-adjusted Charlson comorbidity index.ResultsWe enrolled 45 patients aged 65-79 years and 32 patients ≥80 years. Patients ≥80 years had significantly higher rates of Charlson comorbidity index (9.2 ± 2.4) than younger patients (6.5 ± 2.5; P < 0.001). Arterial hypertension, renal failure, and dementia were significantly more prevalent in octogenarians (P < 0.05). Patients aged ≥80 years had a significantly longer length of hospitalization, while the intensive care unit stay was similar between groups. In-hospital mortality was significantly greater in those ≥80 years (n = 3, 9.4% vs. n = 0, 0.0%; P = 0.029), whereas no differences in 90-day mortality or 30-day readmission were observed. In the second-stage analysis, significant improvements in blood infection parameters and neurologic status were detected in both groups. Of adverse events, pneumonia occurred significantly more frequently in patients aged ≥80 years.ConclusionsSurgical management leads to significant improvements in both laboratory and clinical parameters in older patients. Nevertheless, a personalized medical approach is mandatory in frail patients, especially octogenarians. A clear discussion regarding the potential risk is unambiguously recommended.Copyright © 2022 Elsevier Inc. All rights reserved.
