    “Bamboo Spine” in Ankylosing Spondylitis

    This lateral view of the cervical spine shows a rigid cervical spine in a patient with severe, long-standing ankylosing spondylitis. The spine is completely ankylosed (“bamboo spine”) due to syndesmophytes, fused facet (apophyseal) joints, and paraspinal ligamentous calcification.
