Abstract
This is a retrospective review of 26 patients with chronic intractable pain in which dorsal column stimulation was used as a salvage procedure. On follow-up of 12 to 42.7 months, 21 of the patients had diminished narcotic usage. Seventeen patients subjectively rated their pain relief as good to excellent. Another five patients reported some relief of pain. Two-thirds of the patients reported an increase in their ability to perform daily activities such as walking, stair climbing, and time spent sitting. There are still many technical problems that plague this procedure, as evidenced by a very high technical complication rate of lead migration and lead breakage. Whether or not results diminish over long-term follow-up remains to be seen.
