Background Context-Systematic reviews of lumbar fusion outcomes in purely workers' compensation (WC) patient populations have indicated mixed results for efficacy. Recent studies on lumbar fusions in the WC setting have reported return-to-work rates of 26-36%, re-operation rates of 22-27%, and high rates of persistent opioid use two years post-surgery. Other types of lumbar surgery in WC populations are also acknowledged to have poorer outcomes than in non-WC. The possibility of improving outcomes by employing a biopsychosocial model with a continuum of care, including post-operative functional restoration in this "at risk" population, has been suggested as a possible solution.
