Tyler J Christensen, M Scott DeBerard, Anthony J Wheeler Department of Psychology, Utah State University, Logan, UT, USA Purpose: The prevalence of radiofrequency zygapophyseal joint neurotomy (RFN) has increased substantially across the past decade.Limited research exists that has examined pre-procedure predictors of RFN outcomes, particularly within workers’ compensation populations. The purpose of this study was to determine if pre-procedure biopsychosocial variables are predictive of outcomes in a cohort of compensated Utah patients who have undergone RFN.Patients and methods: This was a retrospective cohort study consisting of a review of pre-procedure medical records and a telephone outcome survey. The sample consisted of 101 compensated workers from Utah who had undergone RFN. Fifty-six patients (55%) responded to the outcome survey. Patients were an average of 46 months post-neurotomy at the time of follow-up. Outcome measures included patient satisfaction, disability status, Roland–Morris Disability Questionnaire, Stauffer–Coventry Index, and Short-Form Health Survey-36 (v.2). Statistical techniques utilized included frequencies, mean comparisons, and logistic and multiple regressions.Results: Forty percent of patients were totally disabled at the time of follow-up. Lawyer involvement, older age, and a positive history of depression were predictors of poor outcomes in logistic and multiple regression equations.Conclusion: Presurgical biopsychosocial variables were predictive of multidimensional patient outcomes, and a high rate of total disability was observed. Additional research on the effectiveness of RFN for workers’ compensation patients is recommended.
