Study Design. Retrospective Cohort StudyPurpose. The aim of our study was to determine the rates and indications of reoperations following primary lumbar fusion, as well as the independent risk factors for early and late reoperation.Methods. We retrospectively reviewed patients who underwent lumbar fusion surgery between January 2017 and September 2020. All patients were followed up for more than 1 year. Characteristics, laboratory tests, primary diagnosis and surgery-related variables were

Multivariable logistic regression analysis was used to identify independent risk factors for early and late reoperations.Results. Of 877 patients included in our studies, 34 patients underwent early reoperation, and 35 patients underwent late reoperation. The cumulative reoperation rate was about 3.9% (95%CI, 2.6%-5.2%) at three months,5.6% (95%CI, 4.1%–7.1%) at 1 year and 7.1% (95%CI 5.4%–8.8%) at 2 years. Multivariable analysis indicated that osteoporosis (odds ratio [OR] 3.8, 95%CI 1.3-10.9, p=0.01) and diabetes (OR 2.2, 95%CI 1.1-4.5, p=0.03) were independently associated with early reoperation and multilevel fusion (OR 2.4, 95%CI 1.0-5.5, p=0.03) was independently associated with late reoperation.Conclusions. The most common reasons for early reoperation and late operation were surgical site infection and adjacent segment diseases, respectively. Osteoporosis and diabetes were independent risk factors for early reoperation and multilevel fusion was independent risk factor for late reoperation. Surgeons should pay more attention to these patients and future studies should consider the effects of follow-up periods on results.
