Overview
Am I A Candidate For X Stop Spinal Surgery ?
You may be a candidate for the X Stop spinal surgery if you have primarily leg pain rather than mostly back pain and your pain is due to spinal stenosis/ foraminol stenosis. Your leg pain is worse with prolonged standing and bending backwards. You must get significant relief of your pain when you sit down and bend forward or stand and bend forward.
Advantages Of X-Stop Procedure :
- It is done on outpatient basis and is performed under local anesthesia
- Patients are home within 24 hours in most cases
- Minimal invasive procedure do not requires no removal of bone or tissue and usually do not require pain medication
- The implant is designed to remain in place without being attached to bones or ligaments
- The procedure is reversible if needed
What Is Spinal Stenosis ?
Spinal stenosis is a narrowing of the spinal canal. Some patients are born with this narrowing, but most often spinal stenosis is the result of a degenerative condition that develops in people over the age of 50. Spinal stenosis is the gradual result of aging and “wear and tear” on the spine from everyday activities. Degenerative or age-related changes in our bodies can lead to compression of nerves (pressure on the nerves that may cause pain and/or damage).
As we age : -
- the ligaments of the spine can thicken and calcify (harden from deposits of calcium)
- bones and joints may also enlarge
- bone spurs, called osteophytes, may form
- discs may collapse and bulge (or herniate)
- one vertebra may slip over another (called spondylolisthesis)
Diagnosing
Before confirming a diagnosis of stenosis, it is important for your doctor to rule out other conditions that may produce similar symptoms.
In order to do this, most doctors use a combination of techniques, including:
History : -
Your doctor will begin by asking you to describe any symptoms you have and how the symptoms have changed over time. Your doctor will also need to know how you have been treating these symptoms, including medications you have tried.
Physical Examination : -
Your doctor will then examine you and check for any limitations of movement in your spine, problems with balance, and signs of pain. Your doctor will also look for any loss of reflexes, muscle weakness, sensory loss, or abnormal reflexes.
Tests : -
After examining you, your doctor may use a variety of tests to confirm the diagnosis.
Examples of these tests include:
X-ray : -
shows the structure of the vertebrae and the outlines of joints.
MRI (Magnetic Resonance Imaging) : -
provides a three-dimensional view of our back and can show the spinal cord, nerve roots, and surrounding spaces, as well as signs of degeneration, tumors or infection.
CAT Scan (Computerized Axial Tomography) : -
depicts the three-dimensional shape and size of your spinal canal and bony structures surrounding it.
Myelogram : -
highlights the spinal cord and nerves after a dye is injected into your spinal column, which appears white on an X-ray film
The X STOP procedure
The x-stop spinal surgery procedure may be performed in either the operating room or special procedures room at the hospital. Using local anesthesia and with the help of X-ray guidance, the X STOP implant is inserted through a small incision in the skin of your back. Alternatively, your surgeon may elect to use general anesthesia.
You will be placed on your side during the procedure so that you can bend your spine when the X STOP is inserted. The surgery to implant the X STOP typically lasts 45 minutes to an hour-and-a-half. During this time you may be awake and able to communicate with your doctor.
Why May X STOP IPD Work ?
The X STOP implant is designed to keep the space between your spinous processes open, so that when you stand upright the nerves in your back will not be pinched or cause pain. With the X STOP implant in place, you should not need to bend forward to relive your symptoms.
X STOP IPD : Clinical Study Results
The X STOP IPD System was tested in a carefully controlled research study that took place in nine hospitals across the United States. In this study, 100 patients with lumbar spinal stenosis had x-stop spinal surgery with the X STOP device. These patients were compared to 91 patients who did not have surgery, but were treated by their doctors in other ways (for example, with medications, corsets, physical therapy, etc.).
Approximately half of the patients who received the X STOP device in this two-year research study experienced a degree of pain relief and ability to increase their activity levels that was sufficient to be considered a successful outcome at two years after the surgery. The clinical benefit beyond two years has not been measured.
The likelihood of needing an additional operation during the study was low. During the study, 6% of patients did not have a satisfactory treatment outcome and decided to have a laminectomy operation (removal of part of the vertebra in the spine), at which time the X STOP was removed.
In addition, the implant dislodged (moved out of proper position) in one patient after a fall, and the implant was later removed. A second operation was also required in three other X STOP patients for the following conditions: drainage of a collection of blood, drainage of fluid around the wound, and removal of damaged tissue with secondary closure of the wound (allowing the wound to close on its own). Overall, 90% of patients had significant improved clinical outcome with visual analogue pain scale (VAS), Oswestry disability score/index (ODI), were achieved.
