Relevance of studying axial syndrome in spondyloarthritis (review of literature)

The article reports the problems of sacroiliitis and spondylitis in patients with ankylosing spondylitis and psoriatic arthritis. Based on the concept of primary involvement the sacroiliac joint in inflammation, they are most often is the object of investigations. But inflammatory changes also affect the spine that’s called the spondylitis. Due to the widespread introduction of medical imaging, scientists know the various variants of axial characteristic in inflammatory spondylopathies: angular (Romanus lesion) and non-angular spondylitis (Andersson lesion, osteitis of the arch, inflammation of the facet joints). However, generally accepted criteria for assessing inflammation of the spinal column in these pathologies have not been developed. Also, frequency of these lesions is not researched. Further study of various variants of spondylitis in ankylosing spondylitis and psoriatic arthritis is necessary, since these data will significantly contribute to the understanding of axial involvement in inflammatory spondylopathies.
