A facet joint nerve radiofrequency ablation (rhizotomy) involves "burning" of a very small nerve that goes to (innervates) the
facet joint of the spinal column, either in the neck or low back. It is preceeded by a positive diagnostic facet medial branch
nerve block. There will not be any permanent numbness or weakness following this procedure.
Facet joint nerve radiofrequency ablation (rhizotomy) is performed in a similar manner as the previously performed diagnostic
facet joint nerve blocks. The difference being that special needles are used to burn these nerves. Small amount of electricity
is used to pinpoint the location of the nerves and the patient will be asked about any pressure, tingling, pain sensation in the
back as the nerves are identified. Burning the nerve will cause a permanent or semi-permanent block of only these pain fibers.
Motor (movement) and sensory ( touch ) fibers are not affected by this procedure.
The procedure may take between 45 and 60 minutes to be performed. Band-Aids may be applied to the needle sites. A nurse
will monitor the blood pressure and pulse, and then review the discharge instructions with the patient before going home on
the same day.
