What is Anterolisthesis?

The vertebrae are bones that protect the spinal cord. Spondylolisthesis results from the vertebrae slipping out of position, causing a wide range of issues. Anterolisthesis is a specific type of spondylolisthesis where the upper vertebral body slips forward on the vertebra below it, usually in the low back. Depending on the degree of slippage, symptoms can range from nonexistent to debilitating.

1. Causes

The exact cause remains unknown, but anterolisthesis often develops following sudden blunt trauma or fracture, such as in a fall or a vehicle accident. Some people develop anterolisthesis due to long-term, strenuous exercise like bodybuilding. Others may have anterolisthesis due to aging. Anterolisthesis has some links to underlying conditions like arthritis, tumors, and weak bones, as well. Some children are born with a genetic spinal growth issue that later causes anterolisthesis.
