Patients with chronic back pain that has not responded well to other treatments may be candidates for a spinal infusion pump. This device allows localized pre-programmed infusion of pain medications directly to the fluid surrounding the spinal cord. This therapy offers relief to patients suffering with significant chronic back pain that has not responded well to traditional surgical and nonsurgical treatment options. This procedure does, however, involve a minor surgical procedure during which a small medication delivery device is implanted under the skin. A miniature computer allows precise delivery of medication to the spinal nerves thus modulating and greatly reducing the pain signals perceived by the patient.
