Description

Some patients suffer from severe remaining or recurrent pain after implantation of a spinal cord stimulation (SCS) system. Therefore a trial of SCS with additional leads for such pain was performed on three patients with chronic regional pain syndrome, one in a leg, one in failed back surgery syndrome, and one in lumbar spinal canal stenosis. Intravenous antibiotics were given before and after the trial in all cases. The trial duration was approximately 24 hours to avoid infection. The pain in every case was decreased to less than 50 % of the pre-trial pain, and new leads were implanted a few months after the trial, also resulting in good pain relief. Despite the short duration of the trial, the patients could evaluate the effect of its stimulation because their experience with it had been sufficient. A trial of SCS with additional leads for patients with remaining or recurrent pain after permanent implantation of an SCS system is thus a valuable procedure to improve the quality of pain relief.
