What risk does anterior sliding of the vertebra pose?

Anterior sliding of the vertebra, also known as anterolisthesis, poses a significant risk of pinching or compressing the spinal cord. When one vertebra slips forward over another, it can disrupt the normal alignment of the spinal column. This misalignment can lead to pressure on the surrounding nerves or the spinal cord itself, which may result in pain, numbness, or weakness in areas of the body that those nerves control. This is particularly concerning in the cervical and lumbar regions, where such displacement can have serious neurological implications.

In contrast, while conditions like arthritis, muscle strain, and reduced flexibility may occur due to various spinal issues, they are not direct and immediate risks associated specifically with the anterior sliding of the vertebra. The primary concern in this context is the risk of neural compromise from the displacement.
