Percutaneous navigable intradiscal decompression in treatment of lumbar disc herniation: a single-center experience

Background/aim: Minimally invasive procedures have been increasingly used for the treatment of herniated discs. Nonsurgicalinterventions minimize the secondary damage to other tissues and shorten the length of hospital stay by avoiding general anesthesia.Possible complications are thermal injuries, root injury, discitis, endplate damage, dural injury, meningitis, infection, increase in pain,and muscle spasm. We aimed to evaluate the efficacy of percutaneous decompression therapy by using intradiscal navigable electrodeson pain and functional movement index in patients with herniated nucleus pulposus (HNP).Materials and methods: A total of 209 patients with protrusive lumbar disc herniation underwent percutaneous ablation decompressiontreatment using an intradiscal routable electrode (L-Disq) in our pain clinic. Visual analog scale (VAS) and Oswestry Disability Index(ODI) scores were recorded at the beginning and at the 1st, 3rd, 6th, and 12th months after treatment. Patient satisfaction was evaluatedat the 12th month by a patient satisfaction scale (PSS).Results: When compared to initial values, VAS and ODI scores showed statistically significant improvement at the 1st, 3rd, 6th, and12th months (P < 0.001). Mean VAS scores were 7.28 and 3.03 points (P < 0.001) while mean ODI scores were 32.46 and 20.48 points(P < 0.001) at the beginning and at the 12th month, respectively. Satisfaction rate of all patients was 81%. We also attempted to treat theexisting annular fissure using an ablation method and we believe that treating the herniated disc together with the fissure in the samesession increased our success rate.Conclusion: With clinical evidence, we suggest that L-Disq may be considered as an appropriate option with a low risk of complicationsin pain management in cases of lumbar disc herniation that are resistant to conservative methods.
