Abstract

Dorsal root ganglionotomy of the S5 nerve is useful for pain around the coccyx. The S5 dorsal root ganglion lies behind the sacrum at a level 1 cm caudal to the S2 foraminal opening and approximately 2 mm lateral to the midline of the sacrum. A small burr-hole was made through the plates of the posterior sacrum to approach the dorsal root ganglion of S5 nerve. Sensory stimulation was performed at 0.3 V, 50 Hz. No motor fasciculations was noted at 0.6 V, 2 Hz. A thermal lesion was created at 75oC for 60 sec. The patient whom we report now was a 67-year-old male who suffered from the pain around the coccyx due to rectal cancer metastasis. He failed to respond to other oral and invasive conventional therapy. We experienced a successful result in the treatment of his intractable pain after the S5 dorsal root ganglionotomy.
