Rationale for change
uworld qid 19491 - patient with ankylosing spondylitis has lower back pain, bilateral buttocks pain and stiffness, has fatigue, lumbar spine and sacroiliacs painrful to deep palpation, elevated ESR, with stooped walking posture.
pateitns will have areas of bony erosions and new bone formation causing the stiff or bamboo spine.
inflammatory cytokines activate osteoclast precursors causing bony erosions -> secondary osteoporosis and compression fractures
during the reparative process, excessive new bone formation occurs filling the previously eroded sites manifesting as the bridging syndesmophytes in vertebral column (bamboo spine) makign the spinal ridgitity, postural alterations, and increased risk of fracture.

{{c2::Ankylosing spondylitis}} is characterized by a(n) "{{c1::bamboo spine}}" appearance on X-ray
Extra
Due to ankylosis (fusion) of vertebrae; can cause restrictive lung disease due to costovertebral and costosternal ankylosis

Ankylosing spondylitis with an unstable ventral C5 dislocation
Lateral x-ray of the cervical spine: unstable ventral C5 dislocation to C6. Typical changes of ankylosing spondylitis with osification of the anterior longitudinal ligament (1) and the posterior ligaments (green area).
Ankylosing spondylitis
Lateral x-ray of the thoracic spine: ventral syndesmophyte formation (green areas) with sclerosis of the anterior longitudinal ligament (red ventral line), subchondral sclerosis of the inferior end plate and superior end plate (red horizontal line), and intervertebral disc space narrowing (1). The changes observed here are consistent with ankylosing spondylitis.
Ankylosing spondylitis
Lateral x-ray of the lumbar spine: ankylosing spondylitis with syndesmophytes (green areas, example shown in 1) and sclerotization of the anterior longitudinal ligament (red line). There is also subchondral sclerosis of the inferior and superior end plates (example shown as 2).
Ankylosing spondylitis (1/2)
Anteroposterior x-ray of the lumbar spine: There are isolated marginal spurs, which partly show horizontal spondylophyte growth in line with degenerative changes (example in 1) and partly vertical syndesmophyte growth (example in 2) in ankylosing spondylitis.
