Recently, I had to undergo epidural lysis procedure as a treatment for my back pain due to prolapsed discs.
The procedure was to help decrease chronic low back pain due to adhesions and scar tissue formation. The physician inserts a catheter into the epidural space in order to access the area of adhesions. This is usually done through the caudal canal, which is located at the base of the spine, via the sacral hiatus (quoting the surgeon’s exact words). The sacral hiatus is a natural opening in the spine near the tailbone. Aided by real-time X-ray imaging, the catheter can be seen on the monitor and directed precisely to the affected nerve root. Once the tip of the catheter is in place, medication can be injected to relieve pain at the source and dissipate the scar tissue.
