It occurs when an upper vertebra slips in front of the one below. Pain is often the first symptom of anterolisthesis.
Misaligned vertebrae can pinch the nerves, and this can have painful and debilitating consequences. Other parts of the body, such as the arms or the legs, can also be affected by anterolisthesis.
The amount of slippage is graded on a scale from mild to severe. Treatment can range from bed rest to surgery. Anterolisthesis is often known as spondylolisthesis.
