Medial Branch Radiofrequency Ablation and Lumbar Multifidi

United States4 participantsStarted 2017-01-01

Plain-language summary

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.
