Introduction
The nerve fibers innervating the annulus fibrosus are the major origin of degeneration-associated discogenic pain. Coblation is a tissue-dissociating technique in which the nerve fibers in the degenerative disc tissue are ablated. We hypothesized that coblation annuloplasty would be an effective maneuver for cervical discogenic pain without radiculopathy.

Aim
To observe the therapeutic efficacy of coblation annuloplasty in patients with cervical discogenic pain without radiculopathy.

Material and methods
Forty patients diagnosed with cervical discogenic pain without radiculopathy were screened for coblation annuloplasty therapy. The patient-rated visual analog scale (VAS) score for pain, significant pain relief rate, and Modified MacNab pain-relieving effect were adopted to evaluate the therapeutic effect within a 1-year follow-up period.

Results
Thirty-three patients eventually completed the study. The average pain duration was 4.6 ±1.6 years (range: 0.5–8 years). The mean VAS pain score decreased from preoperative 6.8 ±0.9 to postoperative 2.5 ±1.3 (p < 0.01). For all participants, the immediate pain relief rate was 78.7% (26/33), which continued to postoperative 6 months. One year later, 22 (66.6%) subjects reported that their pain was significantly alleviated. According to the Modified MacNab criteria, 63.6–82.1% considered the effect of surgery for their pain therapy as “excellent” during the 1-year follow-up period. No significant complications such as hemorrhage, paresthesia, or infection were observed.

Conclusions
This study is the first to demonstrate that coblation annuloplasty is an effective intervention providing significant alleviation of neck pain from cervical discogenic injury without radiculopathy.
