Ankylosing spondylitis (AS) is a type of arthritis from the disease spectrum of axial spondyloarthritis. [5] It is characterized by long-term inflammation of the joints of the spine , typically where the spine joins the pelvis. [ 2 ]
HLA-B27 is a polymorphic form of the HLA-B molecule found in up to 95% of people with ankylosing spondylitis of European ancestry, [16] [17] 70% with reactive arthritis, [18] 60% with psoriatic spondylitis, [12] 25% with peripheral psoriatic arthritis, [17] and 70% with spondylitis associated with inflammatory bowel disease.
Enthesopathy of the pelvis likely due to ankylosing spondylitis Enthesopathy can occur at the shoulder, elbow, wrist, carpus , hip, knee, ankle, tarsus , or heel bone , among other regions. Enthesopathies may take the form of spondyloarthropathies (joint diseases of the spine) such as ankylosing spondylitis , or psoriatic arthritis , plantar ...
When involving inflammation, it can be called spondylitis. In contrast, a spondyloarthropathy is a condition involving the vertebral joints, but many conditions involve both spondylopathy and spondyloarthropathy. Examples include ankylosing spondylitis and spondylosis.
Spondylitis is an inflammation of the vertebrae. It is a form of spondylopathy . In many cases, spondylitis involves one or more vertebral joints , as well, which itself is called spondylarthritis .
The term itself is an umbrella term characterizing a diverse disease family united by shared clinical and genetic features, such as the involvement of the axial skeleton. [2] The 2009 introduced term axial spondyloarthritis is a preferred term nowadays and substitutes the old term ankylosing spondylitis. [3]
Ankylosing spondylitis is a type of arthritis in which there is long-term inflammation of the joints of the spine. [2] Other forms of arthritis may sometimes also lead to ankylosis, including rheumatoid arthritis and reactive arthritis; Osteoarthritis usually confers osteophyte formation, which may eventually fuse across joints. Osteoarthritis ...
