The Effect of Medial Branch Radiofrequency Ablation on Functional Spinal Stability and Lumbar Multifidi Muscle Architecture Assessed by Magnetic Resonance Imaging and Ultrasound Imaging
The purpose of this study is to evaluate the effects of lumbar medial branch radiofrequency
ablation (RFA) on lumbar multifidi muscle size and clinical spinal stability. Specifically,
this study is designed to highlight the comparison of multifidi muscle architecture using
ultrasound imaging (USI) and MRI before and after lumbar medial branch RFA. This study will
also include a commonly utilized functional assessment of the lumbar spine to evaluate the
effects of RFA on lumbar spinal stability.

effects of RFA on lumbar spinal stability.
Radiofrequency ablation (RFA) for the lumbar spine (lower back) is a procedure used to treat
lower back pain secondary to facet arthritis. The procedure ablates (burns) a small nerve
that goes to the arthritic joint in the back. This nerve also innervates a muscle called the
multifidus, thought to be important for lumbar stability. The investigators are conducting a
study to evaluate if RFA has any impact on multifidi size, spinal stability, and overall
function. The tools the investigators will be using to assess the multifidi muscles are
musculoskeletal ultrasound, MRI, physical therapy assessment, and functional questionnaires.
The goal of the study is to determine if RFA impacts the multifidi in a clinically
significant fashion, causing atrophy, spinal instability, and/or functional decline.
