Inclusion criteria
* Predominantly axial pain below the L5 vertebrae * \>75% pain relief from 2 separate lateral branch blocks done on different days (followed by return to baseline pain) * Chronic axial pain lasting for longer than six months: 3 day average VAS between 4 and 8. * Age greater than 18 years. * Failed to achieve adequate improvement with comprehensive non-operative treatments, including but not limited to: activity alteration, non-steroidal anti-inflammatory, physical and/or manual therapy, and fluoroscopically guided steroid injections in and around the area of pathology. * All other possible sources of low back pain have been ruled out, including but not limited to: the intervertebral discs, bone fracture, the zygapophyseal joints, the hip joint, symptomatic spondylolisthesis, tumor and other regional soft tissue structures (this is done by physical exam, medical history, and MRI/CT/X-ray as required)
Exclusion criteria
* Beck Depression Score \>20 or irreversible psychological barriers to recovery * Spinal pathology that may impede recovery such as spina bifida occulta, spondylolisthesis at L5/S1, or scoliosis. * Moderate or severe foraminal or central canal stenosis * Systemic infection or localized infection at anticipated introducer entry site. * Concomitant cervical or thoracic pain greater than 2/10 on a VAS * Uncontrolled or acute illness * Chronic severe conditions such as rheumatoid/inflammatory arthritis * Pregnancy * Active radicular pain * Immunosuppression (eg. AIDS, cancer, diabetes, surgery \<3 months ago) * Worker's compensation, injury litigation, or disability remuneration * Allergy to injectants or medications used in procedure * High narcotics use (\>30 mg hydrocodone or equivalent) * Patients who smoke.
