First of all, It is a simple procedure to get pain relief for disc herniation or degenerative disc disease.
Also, It involves the insertion of the thin needle in the disc & injection of ozone. The specialized ozone generator produces ozone.
The action of ozone is due to the active oxygen atom liberated from breaking down of the ozone molecule. When ozone is injected into the disc, the active oxygen atom (called the singlet oxygen or the free radical) attaches with the proteoglycan bridges in the jelly-like material. Hence, It is called the nucleus pulposus.
As a result, They are broken down and they no longer capable of holding water. As a result, disc shrinks and mummified and there is decompression of nerve roots.
Above all, It is almost equivalent to surgical discectomy. Therefore the procedure is called ozone discectomy or ozonucleolysis.
