Ankylosis Spondylitis


This inflammatory arthritic condition commonly affects the sacroiliac joints and causes progressive spinal ankylosing/fusion. Men are predominately three times more affected than women but the earlier the onset of this condition, the more this disease progresses.

Signs and Symptoms:

  • Low back pain with gradual stiffness upon rising.
  • Low back pain can radiate pain into the buttocks, anterior and posterior thighs.
  • Evidence of a loss of lumbar lordosis, increased thoracic kyphosis and a decrease in chest expansion due to costotransverse joint involvement.
  • Patients may also develop permanent changes in peripheral joints such as hips, shoulders and knees.
