Introduction
Leggett et al in 2015 found mixed evidence for radiofrequency procedures for discogenic pain. Helm et al in 2019 concluded that there was level 1 evidence for the use of biacuplasty for the treatment of discogenic pain.[1]
Lumbar Disc Innervation
Sinuvertebral nerves, formed by a somatic root from ventral ramus and an autonomic root from grey ramus communicans. An ascending branch passes as far as the above vertebral disc. A descending branch supplies the disc at the level of entry
Fusion
There are no sham controlled studies. There are not even any randomised controlled trials with active controls when disc pain has been proven. RCTs on non specific low back pain were negative.[2] Therefore the benefit of fusion surgery for proven disc pain is unknown.
Radiofrequency Procedures
Intradiscal Electrothermal Annuloplasty
Study | N | Arms | Selection Criteria | Results | Comments |
---|---|---|---|---|---|
Freeman 2005[3] |
57 |
|
Provocation CT discography with discrete annular tear or global degeneration |
❌Negative study up to 6 months |
|
Pauza 2004[4] |

|
CT Provocation discography with posterior annular tear only |
❓ “Positive” study, but modest improvements only

Lumbar Disc IN, discTRODE, Ramus Communicans RF
Study | N | Arms | Selection Criteria | Results |
---|---|---|---|---|
Barendse et al, 2001 (RCT)[5] |
13 |
|
1 x positive analgesic discography (>50% relief) |
❌Negative study at 2 months |
Kvarstein et al, 2009 (RCT)[6] |
10 |
|
1 x positive concordant provocation discography (pain >7/10 at 1/3 levels) |
❌ Negative study up to 12 months |
Van Tilburg 2017, (RCT)[7] |
60 |
|
1 x positive block at ramus communicans (decrease NRS 2 or more, placement confirmed with sensory and motor stimulation) |
❌Negative study at 3 months |
Also Ercelen. Evaluated 120s vs 360 seconds at 80 degrees. Active control No difference.

Also Finch 2005, prospective controlled but not randomised. Positive study.

RF procedure different to block procedure. So unclear if the block is predictive, and how many false negatives there would be.
Cooled Radiofrequency Biacuplasty
Study | N | Arms | Selection Criteria | Results | Comments |

Positive provocative discography and negative control. |
✅Positive study 6 months: Mean NRS decrease 2.78 vs 1.32, mean SF-36 increase 15. no significant improvement in ODI (except in post hoc <40 yo patients) Success: 29.6% vs 3.3% (15 point increase in SF-36 and 2 reduction in NRS |

Provocation discography |
✅Positive study 6 months: Mean NRS decrease -2.4 vs -0.56, Treatment response 50% vs 18% 12 months: Mean NRS decrease -2.2, Treatment response 50% SF36 + 64% ODI |
