What is grade 1 anterolisthesis L5 on S1?

Grade 1 anterolisthesis of L5 on S1 refers to a condition in which the fifth lumbar vertebra (L5) has slipped forward on the first sacral vertebra (S1). This can cause a variety of symptoms, including:

* Low back pain

* Pain that radiates into the buttocks and legs

The severity of symptoms can vary depending on the degree of slippage. In some cases, grade 1 anterolisthesis may cause only mild symptoms, while in other cases it can lead to significant pain and disability.

Treatment for grade 1 anterolisthesis typically involves conservative measures, such as:

In some cases, surgery may be necessary to correct the slippage and relieve symptoms.
