SPINAL CORD STIMULATION

Spinal cord stimulation (SCS) is a treatment option for patients suffering from a number of chronic pain conditions, such as Complex Regional Pain Syndrome (CRPS), neuropathic (nerve) pain, failed back surgery syndrome, peripheral vascular disease, spinal cord injury or phantom limb pain.

SCS is only performed after more conservative treatment options have failed, and isn't a treatment option for every patient. It involves a surgical procedure to implant a generator (battery) and up to three leads (wires) around the spine. The procedure involves an initial trial period followed by permanent implantation, and is reversible if you do not tolerate it.

The SCS works by electronically stimulating the spinal cord or to specific nerves with small amounts of low voltage electricity that blocks the sensation of pain. Using a magnetic remote control, patients can turn the unit on and off or adjust the intensity. The sensations derived from the stimulator are different for everyone, but most patients describe it as a pleasant tingling or vibrating feeling.

Two kinds of SCS systems are available. The more commonly used system is fully implanted and employs a pulse generator and a rechargeable battery that must be replaced over time. The second system relies on radiofrequency, featuring a receiver that is implanted inside the body, with a transmitter and an antenna that are carried outside the body (much like a pager or cell phone).

Your doctor will discuss the risks, benefits and alternatives to this procedure, as well as determine which system is right for you. Feel free to discuss any concerns or questions at that time.

SCS is an option for patients with no untreated drug addictions and who pass a psychological evaluation, do not have an implanted pacemaker, and have successfully completed the initial trial period.

Stop taking aspirin, anti-inflammatory medication (Motrin, Advil, Aleve, ibuprofen, Celebrex, Naprosyn, naproxen, ketoprofen, Feldene, Indocin, Relafen, Mobic), and blood thinners (Coumadin, Aggrenox, Plavix, heparin, Lovenox) 72 hours before your procedure. Also, refrain from eating or drinking after midnight on the night before the procedure.
