Coblation Nucleoplasty

Coblation (ablation + coagulation) nucleoplasty is a technique of vaporization of the NP by the application of high-voltage radiofrequency energy. Using the ablation mode, the wand is advanced into the NP. Then, in the coagulation mode, the wand is withdrawn. This technology uses low temperatures (50-70°) and causes minimal damage to the surrounding tissue. Disc volume is reduced by 10% to 20% at the end of the procedure (15,16). Coblation nucleoplasty provided 80% good results in an open study (17,18).
