Ankylosing Spondylitis

Ankylosing Spondylitis (AS) is a type of spinal problem that causes the back to become stiff and inflexible.  It is caused by initial inflammation of the spine where the ligaments or tendons attach to the bone (spond = bone, itis = inflammation).

As the inflammation settles extra bone is produced by the body and this can lead to bony bridges being formed between the vertebrae and stiffness follows this. This is the ankylosing part of the name.

• AS affects about 1 in 200 men and 1 in 500 women in the UK.
• It can affect anyone but usually shows up in late teens or early twenties.
• Occasionally, the diagnosis of AS is missed in younger life and is only made when someone is older.
• It’s a bit hard to diagnose in the early stages as there may be no X-Ray changes, and it can be mistaken for simple lower back pain.
• The condition usually starts at the base of the spine in the sacroiliac joints.
• It can affect other joints, mainly the hips, shoulders and feet and ankles.

Symptoms of ankylosis

• Gradual onset of lower back pain and stiffness. The important thing here is the stiffness, usually worse in the morning and taking a good while to improve on rising. I have met sufferers of AS who are stiff for an hour or more on rising in the mornings.
  
  
• The stiffness usually wears off with exercise and movement as the day goes on.
  
  
• The lower back pain may radiate into the legs and buttocks.
  
  
• Weight loss, fatigue and fevers with night sweats often accompany the illness.

AS is a progressive disease that does need ongoing management but it can be controlled in most people and is not life threatening.

Treatment for Ankylosing Spondylitis

The main ways that this is managed is using medication and exercise.

The main drugs prescribed are:

• Pain killers
• Non-Steroidal anti-inflammatory drugs
• Disease modifying drugs (DMARDS)
• Cortico steroids - either as a joint injection or tablet
• New drugs called Anti TNF medication can also be given.

Most of these need to be prescribed and managed by a rheumatologist.

The exercise programme needs to be tailored to your individual needs and carefully supervised. If you suspect you have AS discuss it with your doctor and if you have been diagnosed with this then you should have regular contact with your own physiotherapist and rheumatology specialist.
