DREZ lesions for relief of pain related to spinal cord injury.

Fifty-six patients with intractable pain following a spinal cord injury were treated with dorsal root entry zone (DREZ) lesions. After a follow-up period ranging from 6 months to 6 years, 50% of patients had good pain relief. Certain pain syndromes tended to respond better to DREZ lesions than did others. Patients with pain extending caudally from the level of the injury and patients with unilateral pain were most likely to obtain pain relief from the procedure; diffuse pain and predominant sacral pain did not respond as well.
