Spinal Cord Stimulator Implant Surgery
For Pain Relief From Reflex Sympathic Dystrophy And Failed Back Syndrome
Back and leg pain often have causes which either improve on their own or which the surgeon can correct (such as pressure on the nerve roots). Sometimes there is no easily correctable cause of the pain.
Among other things, scar tissue around the nerves or chronic inflammation of the nerves such as arachnoiditis may cause leg and back pain. When the neurosurgeon feels that open surgery to decompress the nerves is unlikely to help the pain, an operation to implant a spinal cord stimulator may be very beneficial for the patient.
For reasons not completely understood, the stimulator sends electrical impulses to the areas of the spinal cord causing the pain and interferes with the transmission of pain signals to the brain. It blocks the brain’s ability to sense pain in the stimulated areas, thus relieving pain without the side effects that medications can cause. The electrical impulses can be targeted to specific locations and, as pain changes or improves, stimulation can be adjusted as necessary.
Before implanting a permanent stimulator, the patient will undergo a trial stimulation period to see if the stimulation helps with their pain. If it does, a permanent stimulator may be implanted. A battery pack will also be implanted to provide charge to the stimulator.
