This population-based cohort analysis found a 25.6% prevalence of PSPS II within one year post spinal surgery and 31.5% within two years post spinal surgery. Identified risk factors include old age, being a woman, economic poverty, comorbid status, underlying disability, type of surgery, and lumbar-level surgery. A large dataset was used to document the prevalence and risk factors for PSPS II post spinal surgery.
