If achieved, despite targeted joint blocks no lasting improvement can, in this case, a degradation (neurolysis) of the respective nerves supplying the facet joints help. This is a longer-lasting pain relief (3-18 months) is possible, so that patients can better exercise physiotherapy. Simultaneously, a chronic pain syndrome from the pain repressed memory better and thus the entire situation will be favorably influenced pain.
For the facet joint degradation, there are two methods:
Chemical degradation: Here with the help of neurotoxic solutions such as alcohol (ethanol 94%) or a sugar solution (glucose 5%) on chemical use of existing nerve deserted a respective joint.
Thermal degradation: These are deserted, with the help of high-frequency current supplying the nerves (dorsal rami medialis) of the respective joints. We put one of the most modern pain generators. The treatment is an outpatient basis under local anesthesia and, instead, with or without sedation. After CT-guided placement of special probes is first sought by using a special procedure, the nerve and then deserted specifically about 90 ° C temperature.:
