An international physician group writing in the British journal Annals of the Rheumatic Diseases, has updated recommended parameters that constitute lesions in the sacroiliac joints of patients with spondyloarthritis. The definitions of capsulitis, enthesitis, fat lesion and erosion were revised and new definitions were developed for joint space enhancement, joint space fluid, fat metaplasia in an erosion cavity, ankylosis and bone bud.
