Final answer:
The Buford Complex involves a thickening of the anterior longitudinal ligament, an important structure for spinal stability.
Step-by-step explanation:
A Buford Complex is an anatomical variant that is characterized by a cordlike thickening of the anterior longitudinal ligament. This ligament is crucial as it runs the length of the vertebral column, uniting the anterior aspects of the vertebral bodies. It provides important support to the vertebral column, ensuring stability and protection for the spinal cord and nerves.
