In case of small lumbar disc prolapsis we offer radiofrequency ablation with Cosman RF technology. Under CT-control and under local anestesia a very thin needle is inserted into the intervertebral disc. Due to the permanent CT-control  safety is ensured. Then intervertebral disc ablation is done. In addition, after ablation, betamethasone is injected, which removes the release of the nerve root. Ablation leads to the wrinkling of the intervertebral disc, and then to a decrease and shrinkage of disc hernia. The process of wrinkling and resorption takes about 6-12 weeks.
