Minimally invasive procedure to relieve pain caused by disc degeneration or Annular tear or small disc herniation.
Electrothermal catheter or Radiofrequency needle is inserted under X-Ray/ Fluoroscopic guidance and maneuvered to locate the diseased portion of the disc.
The temperature of the needle or catheter is increased, raising the temperature of damaged disc wall. The heat shrinks and repairs the tear in the disc wall. It also burns the nerve endings causing pain.
