Intradiscal Electrothermal Therapy

This is a minimally invasive treatment, for spinal disc related chronic low back pain. In it controlled levels of thermal energy are applied on the site of the disc that was affected with an annular tear.

How is it performed?

The procedure comprises of the following steps:

  • A flexible catheter is inserted into the specific disc area under x-ray guidance and navigated in proper direction.
  • The terminal portion of the catheter is placed along the posterior disc wall and then it is gradually heated to 90 degrees for 15 to 16 minutes.
  • After this the catheter is removed and the disc is injected with a small amount of antibiotic and anesthesia to lessen discomfort and the risk of infection.
  • In case the catheter is not fully advanced along the posterior disc, the thermal treatment is performed and then a second catheter is inserted from the opposite side and the second thermal treatment is carried out.

Alternative to Invasive Surgery

Who are the candidates?

Patients having two discs as the main source of lower back pain are the right candidates for the IDET Therapy.

How long it takes?

The entire therapy takes less than one hour.


When the disc is heated it takes several days to get settled. The patients after going through this are advised to halt their usual activities that stress their lower back. Our physicians will prescribe some medicines to cure the discomfort.


Patients start experiencing relief, within 12 to 16 days following the procedure.
