Purpose
The primary objective of this randomized controlled trial is to evaluate the safety and efficacy of the TransDiscal System (TDS) in treating discogenic pain of the lumbar spine using a modified disc biacuplasty procedure. The primary efficacy measure will be the Visual Analog Scale (VAS) at 6 months post treatment/randomization and the TransDiscal System will be compared against medical management (standard of care).

Primary Outcome Measures:
- Change in Average Daily Pain Visual Analog Scale (VAS) Score Between Screening and Follow up. [ Time Frame: Baseline and 6 months ]Visual Analog Scale (NRS) - score range = 0 - 10. "0" corresponds to "no pain" and "10" indicates "worst pain imaginable". The means of these scores and their respective standard deviations are reported for each study group.
Secondary Outcome Measures:
- Percentage of Study Group Subjects With Greater Than 2 Points Decrease or 30% Drop in Average Daily Pain Related Visual Analog Scale (VAS) Score. [ Time Frame: Baseline and 6 months ]Visual Analog Scale (NRS) - score range = 0 - 10. "0" corresponds to "no pain" and "10" indicates "worst pain imaginable". The means of these scores and their respective standard deviations are reported for each study group.
- Mean Change in Score of Short Form 36-Physical Functioning (SF36-PF) From Screening to 6 Month Follow up Visit [ Time Frame: Baseline and 6 months ]Short Form 36-PF - score range = 0 - 100. "0" corresponds to "greatest disability" and "100" indicates "no disability". The means of these scores and their respective standard deviations are reported for each study group.
- Mean Change in Score of EuroQuol 5d Visual Analog Scale (EQ-5d VAS) Between Screening and 6 Month Follow up Visit [ Time Frame: Baseline and 6 months ]EQ-5d VAS - score range = 0 - 100. "0" corresponds to the "worst imaginable health state" and "100" indicates the "best imaginable health state". The means of these scores and their respective standard deviations are reported for each study group.
- Mean Change in Score of Beck's Depression Inventory (BDI) Between Screening and 6 Month Follow up Visit [ Time Frame: Baseline and 6 months ]BDI - score range = 0 - 63. "0" corresponds to "minimal depression" and "63" indicates "severe depression". The means of these scores and their respective standard deviations are reported for each study group.
- Mean Change in Score of Patient Global Impression of Change (PGIC) Between Screening and 6 Month Follow up Visit [ Time Frame: Baseline and 6 months ]PGIC - score range = 1 - 7. "1" corresponds to "very much improved" and "7" indicates "very much worse" pertaining to overall activity, symptoms, emotions, and quality of life. The means of these scores and their respective standard deviations are reported for each study group.
- Mean Change in Score of Oswestry Disability Index (ODI) Between Screening and 6 Month Follow up Visit [ Time Frame: Baseline and 6 Months ]ODI - score range = 0 - 100. "0" corresponds to "no disability" and "100" indicates the "maximum disability possible". The means of these scores and their respective standard deviations are reported for each study group.

Detailed Description:
The intervertebral discs serve as joints between the vertebral bodies, providing both structural support and flexibility to the spinal column. Intervertebral discs do not remain structurally intact over a lifetime and degenerate as a natural part of aging. Degenerated discs do not react to stresses and forces the same as healthy discs. When too much stress is applied to a degenerated disc, tears can result. Evidence suggests that when a tear is present, sensory nerve endings can grow into the tear and transmit pain.
The TransDiscal System (TDS) is a medical device that is used in a procedure called Disc Biacuplasty and is currently available in the United States and throughout the world. The TDS enables the back of the disc to be heated to high enough temperatures to ablate the nerves inside that are transmitting pain, while maintaining low enough temperatures to prevent damage to surrounding tissues. The TDS uses two electrodes, located at the ends of two thin probes, which are placed on both sides of the back of the intervertebral disc by inserting them through the skin into the disc using x-ray guidance. Radiofrequency (RF) current flows in the disc between the two electrodes, heating the tissue in the disc to the desired temperature. The study evaluates a modified heating protocol than what is currently in clinical use which should allow for a larger area of the back of the disc to be heated.

Criteria
Inclusion Criteria:
- Age ≥21 years
- Able to understand the informed consent and able to complete outcome measures
- Objective measurements indicating functional impairment related to low back pain
- Stabilized on pain medication regimen for >2 months as defined by a <10% change in dosage
- History of chronic low back pain (>6 months) unresponsive to non-operative care (including physical therapy, anti-inflammatory medication, epidurals, diagnostic facet joint/medial branch blocks, and sacroiliac joint interventions as performed or deemed appropriate by the Investigator)
- Score ≥5 on the Visual Analog Scale (VAS) relating specifically to the average daily low back pain
- Back pain more prominent than leg pain which is commonly exacerbated by flexion or bending or prolonged sitting.
- Single level concordant pain reproduction present on lumbar discography in desiccated disc. Magnetic resonance Imaging (MRI) image also supports discography findings. Changes in other disc spaces in the lumbar region do not demonstrate neural compressive lesion.

Exclusion Criteria:
- Evidence of compressive radiculopathy with predominant leg pain
- Evidence of nucleus pulposus herniation or free disc fragments on MRI
- Evidence of > 2 discs dessicated based on MRI or symptomatic involvement of more than one lumbar disc levels.

- Prior lumbar surgery of any kind at the treatment level (micro-discectomies, and/or minimally invasive procedures at other levels that are not excluded)
- Prior spinal fusion below the T10 Level
- Symptoms or signs of lumbar canal stenosis at any level
