Further observations on spinal meningeal nerves and their role in pain production

Summary

Fifty-one cases of patients with back problems plus radiculopathy following the standard laminotomy or laminectomy for disc or spur excision were subjected to spinal meningeal denervation procedures. The results have been satisfactory.

An autopsy finding on a patient with two previous disc surgeries was reported. There was considerable anatomical disruption of the meningeal nerves with myxoid intrafascicular changes similar to a Morton's neuroma (perineural fibromatosis), but with intact intradural spinal nerves, indicating that the damage to meningeal nerves may have been the cause of her pain.
