Thirty-one patients of chronic pain treated with dorsal column stimulation (DCS) are reported. All of them had been treated previously with drugs and multiple procedures including injections and frequently several operations. After a trial of percutaneous DCS, permanent implantations were carried out. The patients have been followed for up to eight years. Overall, sixty per cent of patients had good to fair relief of pain with DCS. Some of them had a good response for five years and more.
