Ankylosing spondylitis peripheral joint Hip involvement.
This post has been made in conjunction with Dr Joe Thomas, a Senior Consultant Rheumatologist in Kochi India with a vast amount of clinical experience. He also happens to have a very strong interest in Imaging of Arthropathies and has joined us to bring a clinical perspective to the imaging and to advise on what rheumatologists want when we report their referrals.
This is the first of what will be many joint posts with Joe on Imaging in Arthropathies.
HOW COMMON IS IT:
Hip involvement in Ankylosing spondylitis has been reported in up to a 1/3rd of patients and is usually bilateral.
WHY DOES IT OCCUR:
- Its primarily an inflammatory process. This results in cartilage destruction and loss of joint space.
- Eventually it can result in joint fibrosis and ankylosis.
WHO GETS IT:
- The younger the age of onset of AS, the more likely hip involvement is.
- Peripheral joint involvement increases with increasing duration of AS.
WHAT CAN BE DONE:
THR can result in in improved hip function and mobility.
On the AP X-ray for anyone with an axial Spondyloarthropathy, don’t forget to assess and comment on the hip joints.
