Ankylosing Spondylitis (AS)
AS is an inflammatory condition of the spine that causes autofusion and straightening of the spine. Symptoms include pain and deformity in the spine. AS patients also are susceptible to osteoporosis and fractures.
Notice the forward posture on the xray to the left with the patient’s head not even captured on the xray. This patient had great difficulty seeing straight ahead until a pedicle subtraction osteotomy was performed at L3 to enable the patient to stand more erect.
