What is Superion® Interspinous Spacer (ISS)?
What is Superion® Interspinous Spacer (ISS)?
The Superion® InterSpinous Spacer (Superion Spacer) is a small H-shaped spinal implant system for the treatment of moderate lumbar spinal stenosis implant. The device fits between two adjacent bones (spinous processes) in the lower back. This limits movement (extension) at the level where the device is placed. The Superion Spacer is made of titanium alloy.
Features of the Superion System:
- One piece, expandable implant
- Minimally invasive midline approach
- Motion preserving
- Tissue sparing and fully reversible
FIRST IN FLORIDA: Vertiflex Superion Interspinous Spacer Tx for Lumbar Spinal Stenosis
If standing or walking causes pain,weakness or fatigue in the legs, you’re probably suffering from lumber spinal stenosis or LSS. As you stand or walk, the lumbar curvature becomes more pronounced, the spinal nerve more crowded, and the back and legs more painful.
The aim of the Superion spacer is simply to hold the spine in the same open and neutral position as when sitting.
You are a candidate for this simple outpatient procedure if the following are true:
1) you suffer from neurogenic claudication from spinal stenosis: increased pain and tiredness in the buttocks or legs with walking that is relieved with sitting.
2) you have 2 or fewer levels of severe stenosis in the spine
3) the main level is not at the L5-S1 level
4) you want to avoid back surgery
How does it work?
The Superion® ISS system is designed to deliver the implant through a single small incision in the patient’s back. The procedure can be performed under local anesthesia on an outpatient basis and closed with a single suture. Spinal stenosis is a narrowing of the passageways in the spine. When the spinal cord and nerve roots get pinched or compressed during extension of the spine due to the narrowed passageways, this can cause pain, numbness, tingling ,weakness in the leg(s) or legs and back. The device is designed to limit extension of the spinal level to relieve these symptoms.
When is it used?
The Superion Spacer treats patients who suffer from pain, numbness, cramping in their buttock, groin, or legs with or without back pain. The Superion Spacer is used in patients who have difficulty with daily physical activities and who experience relief in flexion from their symptoms.
Spinal stenosis symptoms are often characterized as:
- Developing slowly over time, or slow onset
- Coming and going, as opposed to continuous pain
- Occurring during certain activities (such as walking)
- Feeling relieved by rest (sitting or lying down).
The symptoms of lumbar stenosis generally develop slowly over time and symptoms may come and go. Lumbar stenosis symptoms may include:
- Leg pain
- Leg pain with walking (claudication)
- Tingling, weakness or numbness that radiates from the lower back into the buttocks and legs.
Many people have evidence of spinal stenosis on X-rays, but may not have signs or symptoms. When symptoms do occur, they often start gradually and worsen over time. Symptoms vary, depending on the location of the stenosis:
- In the neck (cervical spine).Cervical stenosis can cause numbness, weakness or tingling in a leg, foot, arm or hand. Tingling in the hand is the most common symptom. Nerves to the bladder or bowel may be affected, leading to incontinence.
- In the lower back (lumbar spine).Compressed nerves in your lumbar spine can cause pain or cramping in your legs when you stand for long periods of time or when you walk. The discomfort usually eases when you bend forward or sit down.
What will it accomplish?
The device should help relieve the symptoms of moderate lumbar spinal stenosis by blocking extension of the affected spinal level.
When should it not be used?
Patients should avoid having surgery with the Superion Spacer if they are experiencing any of the following conditions:
- Allergy to metals such as titanium or titanium alloy.
- Spinal anatomy or pre-existing diseases that would prevent implanting the device or cause the device to be unstable once implanted, such as isthmic spondylolisthesis or greater than grade 1 degenerative spondylolisthesis, ankylosis, fracture of the spinous process or other bones in the spine such as the pars interarticularis, or laminaeon either side or both sides of the back, scoliosis, nerve root compression which causes bladder, bowel, or sexual dysfunction.
- Morbid obesity, defined as a body mass index(BMI) greater than 40.
Benefits of Superion device:
- This surgery helps relieve pressure on your spinal nerves.
- The Superion implant is designed to keep your spine still so when you stand upright the nerves in your back will not be pinched or cause pain.
- The Superion implant is intended to allow you to continue to move your back more than with a fusion surgery. With the Superion implant in place, you should not need to bend forward to relieve your pain.
