Abstract
Aim: Low back pain is a leading cause of patient disability in the USA. Our goal was to determine association between patient characteristics and their response to lumbar medial branch block, radiofrequency ablation of medial nerves or lumbar facet joint injections. Materials & methods: Medical records for the first 100 patients who underwent lumbar medial branch block, radiofrequency ablation of lumbar medial nerves or lumbar facet joint injections between 1 September 2019 and 31 March 2020 were reviewed and demographic data were recorded. Results: At the 3-month post-procedure visit, positive responders were significantly more likely to be non obese patients (BMI <30) and those with pain <5-years. Conclusion: Obesity and chronicity of pain certainly are found to be predictors of response to the above mentioned procedures.
