Ans. B. Ankylosing Spondylitis
Bamboo spine is seen in Ankylosing spondylitis (AS).
Ankylosing spondylitis (AS) is an inflammatory disorder that primarily affects the axial skeleton. It is more common in males, Male-to-female prevalence is between 2:1 and 3:1.
Sacroiliitis is often the earliest manifestation of AS. In the spine, there is inflammatory granulation tissue in the paravertebral connective tissue at the junction of the annulus fibrosus and vertebral bone. Ascending progression of this process leads to the “bamboo spine.” Other lesions in the spine include diffuse osteoporosis, erosion of vertebral bodies at the disk margin resulting in “squaring” or “barreling” of vertebrae.
