Study Summary
Chronic, non-neurogenic low back pain (CLBP) is a common condition that affects many individuals across their lives. The lumbar facet joint has been implicated as an important source of CLBP, with a prevalence of 15-45%. Elements of clinical history, physical examination, and imaging (radiographs, standard CT scan, standard MRI sequences) provide poor diagnostic specificity for pain of lumbar zygapophysial joint (Z-joint) origin. Thus, clinicians have traditionally relied upon MBN blocks to confirm or refute this diagnosis. The reference standard for the diagnosis of lumbar Z-joint pain is a positive response to dual comparative MBN blocks, which requires pain reduction of great than or equal to 80% of concordant duration to that expected of two different local anesthetics on independent occasions. Further, dual comparative MBN blocks have a high positive predictive value for determining the clinical outcome of lumbar MBN RFA for the treatment of lumbar Z-joint pain; when patients are appropriately selected using this reference standard and rigorous MBN RFA technique is implemented according to practice guidelines, studies demonstrate excellent clinical outcomes.
Primary Outcome
This is a scale from 0 to 10, with 0 being no back pain at all and 10 being the worst back pain imaginable The primary outcome for this study was the proportion of participants within each group (C-RFA and FJI) who experienced a greater than or equal to 50% reduction in NPRS score at 3 months. Participants were asked to rate their pain over the past 7 days on a scale from 0 to 10.
