In many spinal surgeries, two or more vertebral bones are permanently joined with a technique called "spinal fusion." A fusion creates a solid mass of bone. It stabilizes your spine.

Your spinal nerves travel through your spinal canal and exit through openings we call "foramen." If any of these spaces are too narrow, your nerves become compressed. We say you have "spinal stenosis." It's a problem that most often happens in the neck and lower back.

This problem affects the spinal nerves in your neck. It's a narrowing of the spinal canal. That's the space your spinal nerves travel through. In a healthy spine, the spinal canal protects these nerves. It keeps them free from injury. But with spinal stenosis, the spinal canal is too narrow, and your nerves get compressed.

The nerves that exit the foramen (open spaces on the sides of your vertebrae) may also be compressed. These compressed nerves can cause pain and other problems.

This is a crack that forms in a narrow bridge of bone at the back of a vertebra. A vertebra is one of the bones that forms your spine. Often, this injury happens in the lumbar spine. It can happen to people of all ages. But, we most often see it in children and teens. That's because their bones are still growing.

This condition is a degeneration of the spine that can affect the spine at any level, resulting in pain and discomfort that can grow worse over time.
