What is It?
The Superion InterSpinous Spacer (Superion Spacer) is a small H-shaped device made of titanium alloy that is designed to reduce the symptoms of moderate degenerative lumbar spinal stenosis. The device is implanted between two adjacent bones in the lower back, and limits movement at the location where the device is placed.
How Does it Work?
Spinal stenosis is defined as a narrowing of the passageways in the spine. The narrowing puts pressure on your nerves and spinal cord and can cause pain, numbness, tingling, and/or 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 benefits patients who suffer from pain, numbness, and/or cramping in their buttock, groin, or legs with or without back pain.
What Will it Accomplish?
The device should help relieve the symptoms of moderate lumbar spinal stenosis by blocking extension of the affected spinal level.
