Selective Nerve Root Blocks
If a nerve root becomes compressed, it may cause inflammation and pain. When an imaging study does not clearly show which nerve is responsible for the pain, the selective nerve root block (SNRB) procedure may be used to identify the source. In addition to this diagnostic function, a selective nerve root block may provide therapeutic relief of low back pain and/or leg pain, and also can teat far lateral disc herniation (a disc that ruptures outside the spinal canal).
During a radiofrequency neurotomy, radio waves are sent, via injection, to interrupt pain signals between the brain and the affected nerve. Dr. Pappas delivers heat -generated waves, using image-guided technology to directly target and block the nerve. Up to 50 percent of patients with facet or sacroiliac joint pain experience relief, lasting between 3 and 18 months, after the injection.
