Spinal Cord Stimulator
Helping Patients from North Central Arkansas & South Central Missouri
Spinal cord stimulation, also referred to as neurostimulation, is a minimally
invasive procedure often used to help treat acute and chronic pain. This
procedure is typically used after more conventional methods of treatment
have failed, like physical therapy, medication, injection therapy, and
rest. The procedure involves the application of low voltage electricity
to block the spinal nerves from being able to transmit pain signals. It
is intended to assist patients with pain management and potentially decrease
the amount of pain medication that is normally required to lower your
pain levels. This procedure may be a viable option if you are experiencing
chronic pain in your hands, legs, back or feet, and have not found effective
treatment from the more conventional methods. A slight electric current
will be transmitted from a small, battery-powered generator to your spinal
cord. This will most likely result in a slight tingling feeling, rather
than pain. The procedure is meant to interrupt pain signals, thereby allowing
many patients to return to a normal, active, and healthy lifestyle.
Several medical conditions commonly treated using spinal cord stimulation include:
- Neuritis/Neuropathy
- Arachnoiditis: Painful inflammation of the meninges, accompanied by scarring
- Radiculopathy: Pain that travels down your arms or legs
- Complex regional pain syndrome: Results in pain felt in the arms, hands,
legs, or feet
- Failed back surgery syndrome: Pain that is still felt in the back even
after spinal surgery
- Other chronic pain conditions: Stump pain, spinal cord injury, multiple
sclerosis, and others
Spinal Cord Stimulation Trial Run
On the date of your appointment, please arrive at least 20 minutes prior
to the start of your scheduled procedure. Our nurses will begin an IV
if you will want sedation and then they will conduct a brief nurse pre-operation
assessment. You will be led to the procedure room and our nurses will
get you set up in a hospital bed. Then, you will be provided with nitrous
oxide gas and sedation to help you become more comfortable. At this point,
we place a cold cleaning solution on all our patients to lessen the risk
of infection. Using x-ray guidance, your doctor will proceed to locate
the procedure site and will inject a small amount of numbing medicine.
The shot may sting slightly, but the pain will subside quickly. After,
the doctor will place the epidural needle into the epidural space. Once
the needle’s proper placement is confirmed, the doctor will insert
a small electrode through the needle and into the space. The procedure
is then repeated since the majority of the trials need about two electrodes
to work effectively. Once the electrodes are properly situated, a representative
from the spinal cord stimulator’s device will turn it on and ask
you how it feels. The company’s representative will adjust the device
until you report feeling a pleasant tingling feeling instead of the pain
you have been experiencing. This is painless and usually takes less than
10 minutes. Afterwards, the needles will be taken out and the electrodes
will be taped to your back with a few stitches. The battery will be taped
to your back as well and it will still be connected to the electrodes.
Then you will be given instructions on how to properly care for the device
before you leave our care. This trial will last for five days before you
need to return to our clinic. It is imperative that you thoroughly test
the device by engaging in your normal, everyday activities and observing
how effectively it works to reduce your pain. During this trial, you should
continue taking pain medication as prescribed. When you return to our
clinic, your doctor will take out the electrodes and put a small bandage
over where they used to be located. If you report that the device reduced
your pain levels by at least half, then you will be considered for permanent
implantation of the electrodes.
Spinal Cord Stimulator Permanent Placement
This procedure is only conducted after the patient has reported a successful
trial run, as stated previously. If you are going to receive a permanent
implantation of the spinal cord stimulator from an outside doctor, please
follow their instructions as they can differ from physician to physician.
Permanent implantation of spinal cord stimulators is usually only conducted
in operation rooms and they are typically divided into two categories:
A laminotomy and a percutaneous implant.
Laminotomy
Laminotomies are usually conducted by either a neurosurgeon or an orthopedic
surgeon. This procedure is typically performed in an ambulatory surgery
environment or hospital setting and it requires the application of general
anesthesia. The surgeon will make a small incision in the patient’s
lower back to place the electrodes within it. The electrodes will be secured
and attached to the patient’s spine and ligaments. A laminotomy
is when a tiny amount of spinal bone is removed to make space for the
electrodes. Once they are secured, they will then be sewn into position
by your surgeon. After, they will connect the electrodes to the battery
and sew up all skin incisions. Finally, you will be done and directed
to a separate recovery area.
Percutaneous Implant
Percutaneous implants are performed by a patient’s primary pain physician.
On the day of your appointment, please arrive at least 20 minutes prior
to the start of your scheduled procedure. Our nurses will get you set
up with an IV if you will want sedation and then they will conduct a brief
nurse pre-operation assessment. You will be led to an operation room and
will lie down on a hospital bed. After you are situated in the procedure
room, you will be provided with nitrous oxide gas and sedation in order
to help you become more comfortable. At this point in the procedure, we
place a cold cleaning solution on all our patients to lessen the risk
of infection. Utilizing x-ray guidance, your doctor will locate the procedure
site and inject a small amount of numbing medication. It may sting slightly,
but the small amount of pain will pass quickly. Then, the epidural needle
will be placed into the epidural space and confirmed for proper placement.
Once it is confirmed, your doctor will insert the electrode and repeat
the procedure again in order to place another electrode. After the electrodes
are situated, a representative from the spinal cord stimulator’s
company will turn on the device and ask you to describe how you feel.
Then the representative will adjust the device until you report feeling
a pleasant tingling feeling. Your doctor will make a small incision on
your lower back area and will attach the electrodes just under the skin.
They will then connect the electrodes to the battery and sew up any other
incisions. Finally, you will be taken to a separate room for recovery.
What to Expect Afterwards
You should expect slight pain or discomfort and you should continue to
take your pain medications as directed. You can use over the counter pain
medication and ice for short-term pain relief.
You should avoid these activities for six to eight weeks following the
procedure:
- Twisting, bending, stretching, or lifting anything over five pounds above your head
- Raising your arms above your head
- Sleeping on your stomach
- Sexual activity until after your first follow up appointment with us
Regarding bathing for incision care, you are allowed to shower but you
should not submerge yourself in a bath or pool until after your first
follow up appointment with us. Bandages will fall off gradually after
your procedure and you should leave all stitches and staples in place
until after you meet with us again. Finally, make sure you observe the
site of the incision at least twice daily and make sure it is kept clean
and clear.
Follow Up Visit
You should return to our clinic about 10 days after the procedure in order
to remove your staples and stitches. You may be required to contact the
aforementioned company representative to help create a comprehensive pain
management program.
When you should call your doctor:
- If you have a fever over 101 degrees and it lasts for more than half a day
- If you notice any sign of infection
- If you notice any type of wiring or metal other than the staples or stitches
- If your body develops severe lower back pain, leg paralysis, leg numbness,
or loss of bladder or bowel control
