What is Anterior spondylitic ridging?

Anterior spondylitic ridging refers to the formation of bony ridges along the anterior (front) aspect of vertebrae, often associated with ankylosing spondylitis, a type of inflammatory Arthritis that primarily affects the spine. This condition leads to inflammation and eventual fusion of spinal vertebrae, resulting in stiffness and reduced flexibility. The ridging occurs as a result of new bone formation due to chronic inflammation and can contribute to the characteristic changes seen in X-rays of affected individuals. It is important for diagnosis and monitoring disease progression.
