Transdiscal Biacuplasty

What is disc biacuplasty?

Disc biacuplasty is a TransdiscalÔ system used to treat patients with chronic back pain originating in the spinal disc. Such pain is also known as "discogenic pain". The TransDiscal system consists of a radiofrequency generator, and two water-cooled probe electrodes that maximise the treatment area while minimizing excessive heating. Disc biacuplasty (meaning “two needle treatment of the disc”), targets the pain-generating nerves, and may stop them from transmitting pain signals. This treatment could greatly reduce pain, or even eliminate it.

How does the procedure work?

During the procedure, two TransDiscal probes are inserted into either side of the affected disc through introducer needles. Radiofrequency energy is then passed between the probes which heats the disc tissue between and surrounding the probes. The sensory nerve fibres in the spinal disc that may be responsible for pain are thus deactivated.

Typically during the procedure, you will be asked to lie down on your stomach on a procedural table. Your doctor will then inject local anaesthetic to the areas where the introducer needles will be inserted to minimize discomfort. The introducer needles will be inserted through the skin and into the disc using x-ray guidance. Radiofrequency energy is then applied between the two probes, aiming to treat the sensory nerve fibres that are causing the pain.

How long does the procedure take?

The disc biacuplasty procedure is minimally invasive and takes approximately 30 minutes to treat a painful disc. It is done as an outpatient procedure, does not involve general anesthesia. Your doctor may administer a sedative to keep you comfortable.

What can I do after the procedure?

You will be given medical leave for about 3-5 days to allow you to rest. Specific instructions will also be given to you on the activities you should avoid or limit.
