Ankylosing Spondylitis

Ankylosing Spondylitis

Ankylosing spondtliyis is a disabling condition affecting young patients. It begins with pain and stiffness in the lower back and can spread to involve other joints. The hips and other joints are affected by an inflammatory arthritis. Secondary osteoarthritis of the hip joints result and may need a hip replacement.

It is a genetically transmitted condition. Some patients may acquire it by a mutation. It is a sero negative arthritis. Patients have HLA B27 allogene.


Affected joints are painful and swollen. Later deformities develop. Finally the joints become stiff and deformed. The spine also develops a progressive deformity and the patient stoops forward. Hips develop bony fusion. Movement becomes very difficult. The patient can move only by swinging his pelvis. 

Treatment of hip arthritis
When hips are involved, movement becomes difficult. The patient is bedridden. Bilateral Total hip replacements restore mobiltiy and quality of life. Young patients can thus become productive and start earning their living. They can mobilize independently instead of relying on help of family members or friends.
Hip replacement in these patients is difficult. It requires special anesthetic techniques, adequate exposure and post op rehabilitation. 

This X ray shows both hip joints fused by ankylosing spondylitis. There is complete bony fusion of both hips. This patient needed bilateral total hip replacements.
