The technique of radiofrequency Coblation "nucleoplasty" was evaluated in 34 cases of contained lumbar disc herniation. Intervention was performed after failure of conservative management. Inclusion criteria were complaints of back pain with or without radicular pain, and failure of six weeks of conservative care. The diagnosis of discogenic pain was confirmed with imaging studies "MRI" and positive provocative discography with elicitation of concordant pain. Exclusion criteria were presenting with disc herniation with sequestration, evidence of previous back surgery, infection or spinal instability, and marked spinal stenosis, non-qualifying results on provocative discography, and the presence of progressive neurological deficits.The follow up period was 12 months. This prospective evaluation demonstrated pain relief defined as 2 points or more relief in VAS, in 63% of the patients at 6 months and 50% of the patients at 1 year regarding the back pain. Regarding the leg pain, pain relief was in 92.6% of the patients at 6 months and 92.3% of the patients at 1 year. Our recommendation is to modify the inclusion criteria for Nucleoplasty to include only patients with contained disc prolapse who are younger than 40 years old whose back pain no longer than 9 months.Conclusion: percutaneous disc decompression using radiofrequency Coblation (Nucleoplasty) is a safe and effective procedure in alleviating discogenic back pain, with or without leg pain.
