Radiofrequency Rhizotomy
Diagnosis: ___________________
The patient presents today for
radio frequency rhizotomy of the medial branch nerves of the cervical facet
joints at the C4-C5, C5-C6, and C6-C7 levels on the right/left side.
Procedure: The patient/family member has been informed
of the risks and benefits of the planned procedure. Procedure – radiofrequency rhizotomy of the
medial branch nerves of the cervical facet joints at the C4-C5, C5-C6, and
C6-C7 levels on the
right/left side
Informed consent was
obtained. In the fluoroscopy room, the patient
was placed in a prone position and pillows are placed under the chest to allow
the cervical spine to be moderately flexed without discomfort. The patient’s forehead was allowed to rest on
a folded blanket on a small pillow. An
AP view of the cervical spine was obtained.
The fluoroscopy beam was rotated to view the center of the neural arch. The target level was then identified. The skin was prepped and draped in a sterile
manner. Under fluoroscopic the skin and
deeper tissues were numbed with 0.5% lidocaine.
Under fluoroscopic guidance a 2-inch, 20 gauge radiofrequency probe was
guided to contact the centroid of the neural arch. The needle position was confirmed on AP and
lateral views. Initially sensory
stimulation was done, and then motor stimulation was done. Contractions of the multifida were
noted. No extremity contractions
noted. The impedance at each of the
levels was noted to be
right/left at the C4-C5 level,
right/left at the C5-C6
level,
right/left at the C6-C7 level.
Then using the radiofrequency rhizotomy technique, the medial branch
nerves at each of these levels was lesioned.
The duration of the lesioning was 120 seconds and the temperature was
maintained at 42 degrees. The patient
tolerated the procedure well.
Complications none.
