“X-STOP” INTERSPINOUS PROCESS DECOMPRESSION (IPD)
The X-STOP is a minimally invasive procedure which involves placing a titanium metal implant between the spinous processes of the vertebrae in the back of your spine (Refer to figures). The spinous processes are the prominent bumps that you feel when you run your fingers down your back. By placing the implant between these processes, it indirectly opens the space for exiting nerve roots from the spinal cord, which relieves the compression of the nerve. The procedure does not involve removal of bone. Since the implant is located between the spinous processes, it is not located near the spinal cord or the exiting nerves. The process is reversible and more advanced procedures remain future options. Average length of the surgery is 45 minutes to 1.5 hours.
Pre-operative testing and preparations
Prior to your surgery date, you will be required to undergo routine laboratory
tests, EKG and a chest x-ray. If you are over 50 years of age or have any history of
cardiac or pulmonary problems, you will also be required to have a clearance by a
cardiologist or pulmonologist, respectively. You will also be given information on what
medications, both prescription and over the counter, that need to be discontinued preoperatively
as many can interfere with wound healing and bleeding time.
What to expect in the hospital postoperatively
You will wake up in the recovery room after the operation is over. During this
time you may be disoriented and tired, which is the normal effects of the anesthesia
wearing off. Once stable, you will be greeted by friends and family. Your incision will
be covered by a sterile dressing, which will stay in place for 2 to 3 days.
It is important to begin moving as soon as possible to prevent blood clots and
speed your recovery. You are able to walk the same day as your surgery. As you begin
to heal, slowly increase your activity level. Physical therapy is sometimes necessary
and we will inform you if need be. The procedure is typically done on an outpatient
basis, however, depending on your age and additional medical conditions, it may be
necessary to remain in the hospital overnight. Before your discharge, you will be
provided with a list of “do’s and don’ts” and arrangements will be made for home
health if necessary.
Once you arrive home
You may shower, but do not soak in the bath or hot tub for 4 to 6 weeks.
Once the dressing is removed and you are informed to keep it open to the air,
make sure that you protect it from sun exposure. Once the incision is healed,
sunscreen should be on the incision for 6 months to one year. This will help
decrease its appearance.
Maintain a healthy diet, especially one that is high in dietary fiber to decrease constipation. Additionally, a diet rich in protein is ideal for the healing process.
Drink plenty of fluids.
Monitor your incision. It is common to have a small amount of blood and fluid
leakage, however, if there is persistent drainage contact the office. Additionally,
watch for opening of the incision, redness or warmth around the incision, or fever greater
than 101ºF.
No driving for 4 to 6 weeks or until advised.
No lifting greater than 5 pounds for 4-6 weeks.
No bending at the waist or twisting the back. No jumping, running, or highimpact
sports.
Typical recovery time is 2 weeks to 6 weeks.
