Ankylosing spondylitis
Ankylosing spondylitis represents a relatively rare
condition in which the spine ossifies (lays down bone).
It typically affects young males and will initially
produce pain in the sacroiliac joints.
As the spine becomes more rigid, multiple small stress
fractures may develop. Gravity tends to tip the body
forward, and the patient may develop a flexed forward
posture.
The same process can develop in the cervical spine
(neck) and result in a "chin on chest" deformity.
If the deformity becomes severe, the spine may be surgically
realigned, although this is a large surgical procedure
with significant risk of neurological injury.
Generally, treatment for ankylosing spondylitis is
conservative and the symptoms can be managed with NSAID’s
and physical therapy exercises that concentrate on maintaining
motion in the lumbar spine and hips.
