Radiofrequency thermocoagulation is also a better treatment. Radiofrequency current is a high-frequency alternating current with a frequency of 100 kHz-3 MHz, which utilizes radiofrequency electrodes to form a radiofrequency electric field within the intervertebral disc, and plays a role within a certain range. The temperature generated by radiofrequency energy can vaporize part of the nucleus pulposus of the intervertebral disc, reducing the volume of the nucleus pulposus of the intervertebral disc to achieve the purpose of decompression; it also has a thermal effect, improving local circulation, so that the muscle spasm due to pain can be relieved and improved; radiofrequency thermo-coagulation is also conducive to inflammatory factors, pain-causing factors, as well as sinus inactivation of the spinal nerves. Its advantages include: strong controllability of temperature, time and range, which can effectively avoid thermal damage to the nerve root and greatly reduce the risk of treatment.
