ANKYLOSING SPONDYLITIS & THE HIP: WHAT HAPPENS

HOW COMMON IS HIP INVOLVEMENT IN ANKYLOSING SPONDYLITIS?

Hip involvement in Ankylosing spondylitis has been reported in up to a 1/3rd of patients and is usually bilateral.

WHY DOES IT OCCUR

It’s 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.

KEY POINT ON HIP INVOLVEMENT IN AXIAL SPONDYLOARTHROPATHY

On the AP X-ray for anyone with an axial Spondyloarthropathy, don’t forget to assess and comment on the hip joints.

This post has been made in conjunction with Dr Joe Thomas, a Senior Consultant Rheumatologist at Aster Hospital in Kochi India, who has a vast amount of clinical experience. He also has 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.
