At least 2 branches for each joint are treated in this same manner. The neurotomy takes 30 to 45 minutes, depending on the number of levels to be done. The patient is then recovered in the observation area for 30 minutes to 1 hour. Destabilization of the facet joint is a risk and post injection training to strengthen the extensor muscles can prevent this possibility. The nerve eventually grows back and the procedure can be repeated.
Many patients have a combination of facet and discogenic pain, and require separate treatments.
It is thought that by avoiding the burning, that less damage to the nerve is done, and that there are fewer tendencies for the nerve to want to regenerate. In addition, the pulse radiofrequency creates an Electro-magnetic field that may reprogram the DNA in the nerve to stop pain transmission. This technique was recently FDA approved. The neurotomy takes 30 to 45 minutes, depending on the number of levels to be done. The patient is then recovered in the observation area for 30 minutes to 1 hour.
