Interspinous Spacer (Vertiflex / Superion)
What it is
An interspinous spacer is a small device placed between two bones in the low back. It helps hold open the space for the nerves. It is for some people with spinal stenosis who get leg pain when they walk.
This surgery may be done at GSMC’s surgery center or in a hospital. Your surgeon will explain where. Call 732-202-3000 to learn which surgeon performs it.
Why it is done
- Moderate lumbar spinal stenosis at one or two levels
- Leg or buttock pain with walking that improves with sitting or leaning forward
- At least six months of nonsurgical care without enough relief
- No significant instability, fractures or severe osteoporosis
What to expect
- Before: You meet with your surgeon and may need imaging, blood tests and a health check. You will get instructions about eating, drinking and medicines, including blood thinners. Plan for a ride home.
- During: You get anesthesia or sedation. Using live X-ray, the surgeon places a small spacer between two bones in the back through a small cut.
- After: Most people go home the same day and walk right away. Limit bending and lifting at first. Normal activity often returns in 2 to 6 weeks.
Self-care tips
- Walk a little several times a day.
- Follow your limits on lifting, bending and twisting.
- Keep the cut clean and dry. Follow your wound care instructions.
- Take pain medicine only as directed. Do not smoke; it can slow healing.
When to call us
- Fever over 101°F or chills
- Redness, swelling or fluid draining from the cut
- Pain, swelling or redness in your calf
- New or worse numbness or weakness
Call 911 for chest pain, trouble breathing, or loss of bladder or bowel control.
