Rhizotomy is a surgical procedure in which a nerve root is cut off from the spinal cord. This procedure is used to treat chronic pain caused by conditions such as spinal stenosis, herniated discs, and degenerative disc disease. Rhizotomy can also be used to treat spasticity, a condition in which the muscles become stiff and difficult to control.
The procedure begins by making an incision in the skin over the affected area. The surgeon then carefully locates and separates the nerve root from the spinal cord. The nerve root is then cut, allowing the nerve to be isolated from the spinal cord. After the nerve has been cut, it is cauterized to prevent re-growth of the nerve.
Rhizotomy has been used to treat chronic pain for many years, with success rates ranging from 50-90%. However, it is important to note that this procedure is not without risks. Potential complications include nerve damage, infection, and bleeding. Additionally, the effects of the procedure may not be permanent, and the pain may eventually return.
Rhizotomy is a relatively safe and effective procedure for reducing chronic pain. However, it is important to note the potential risks and to discuss them thoroughly with a medical professional before undergoing the procedure.
