Preparation: To start, the skin of your back is numbed. The doctor inserts a needle called a “cannula” through the numbed skin. A video x-ray device called a “fluoroscope” helps guide the cannula into your bulging disc.
Procedure: The doctor puts a special probe into the cannula and pushes it into your disc. When the probe is turned on, the tip spins. It removes small parts of the center of the disc. This relieves pressure inside the disc, reducing the bulge.
