Although the causes are still being understood by medical researchers, spinal cord stimulation is a form of treatment that offers pain relief for a number of conditions. It works by sending a gentle electrical current into the epidural space near the spinal cord, which then disrupts pain signals traveling to the brain. There are different methods for performing this type of therapy, but the most common is a surgical procedure to place a spinal cord stimulator implant inside of the body.
Chronic pain related to a spine condition, diabetes, heart pain, complex regional pain and other conditions or illnesses can be extremely difficult to live with. While there are effective conservative treatment methods, many people attempt these therapies for weeks or months without finding sufficient relief. In situations where a more intensive surgery is either undesirable or the patient is not a viable candidate, a spinal cord stimulator implant can be an effective alternative.
To help you better understand how a spinal cord stimulator implant works and how surgeons place the implanted device, USA Spine Care is sharing the following informative article. We want to help patients become more engaged in the treatment process and make more informed decisions about their care. Please let us know if you have any questions or would like to learn more about finding relief.
The fundamental design of a spinal cord stimulator implant is a pair of electrodes that are attached to the epidural space of the spinal cord near a painful area. These electrodes are attached by thin wires to a power source, or generator. While the generator can be placed outside the body, such as for a spinal cord stimulator trial period, it is typically placed inside as an implanted device.
For generators that are implanted, there are two primary types:
The type of device used depends on a number of factors, including the location of pain and the surgeon performing the procedure. A key aspect of a positive outcome is for the surgeon to create a successful trail for the wiring between the electrodes and the generator.
The other essential component of a spinal cord stimulator implant is the external control device. This allows the patient to modify the electrical current according to the level of pain signals being experienced. Physicians can provide instruction and feedback on optimal use, including turning the device off while driving or operating machinery.
For patients receiving a spinal cord stimulator implant, the first step will be a trial period to determine if this form of treatment will be effective. This phase typically lasts around a week and involves the surgeon placing the electrodes and lead wires and attaching them to an external generator. The trial procedure is less extensive than even the minimally invasive permanent procedure, often involving little more than a couple of X-ray guided injections.
During this time, patients can learn how the controls work and determine the amount of relief they experience from spinal cord stimulation. It is usually recommended to keep a log of symptoms and the levels of stimulation that offer effective relief. Using this information, the surgeon and patient can work together to determine if a permanent spinal cord stimulator implant is the next phase.
If the answer is yes, an outpatient procedure will be scheduled. First the surgeon will replace the trial electrodes with permanent ones, if needed. Next, he or she will place the implanted device in either the abdomen or lower back depending on optimal placement for the patient and condition. After that, the surgeon will create a successful trail under the skin between the electrodes and the generator. This successful trail is necessary for the electrical signal to travel safely to the spinal cord, thereby disrupting pain signals to the brain.
The surgeon will then close the incisions once the procedure is complete.
Complications associated with spinal cord stimulator implants are rare, but any type of procedure has some level of risk. Like many surgeries, one of the primary risks comes in the form of surgical site infection, which is typically reduced for outpatient procedures, particularly in ambulatory surgery centers.
Since it is an implanted device with a power source, patient injuries such as falls can present the risk of device damage. Patients suffering any type of injury should always inform treatment professionals that they have a spinal cord stimulator implant.
To decrease the risk of any complication, patients should closely follow any and all postoperative instructions and attend required follow-up visits. While spinal cord implant surgery is a minimally invasive procedure with a less extensive recovery than other types of spine surgery, rushing back to activities ahead of guidelines may result in problems.
