    Author: Rath SA, Seitz K, Soliman N, Kahamba JF, Antoniadis G, Richter HP.
    Journal: Stereotact Funct Neurosurg; 1997; 68(1-4 Pt 1):161-7. PubMed ID: 9711710.
    Abstract:
    During a 16 years' period, a total of 79 dorsal root entry zone coagulations were performed in 68 patients for deafferentation pain. Of the 23 patients who underwent surgery for pain due to cervical root avulsion, 18 (82%) had a good (12) or fair (6) pain relief (mean follow-up period 51 months). Twelve (57%) patients with spinal cord injuries noted continuous pain reduction (10 good, 2 fair; mean follow-up 52 months). Continuous marked improvement for longer periods was reported only by 2 out of 10 patients with postherpetic neuralgia and 1 out of 7 patients with painful states due to other brachial plexus lesions and none out of 5 with spinal cord lesions (3) and phantom limb pain (2).
