Is cervical spine involvement in juvenile polyarthritis under-recognized?

[1] study evaluates the frequency of radiological cervical spine involvement in young adults with polyarticular JIA (pJIA) compared with RA patients. The authors show that about two-thirds of patients in both groups had radiographic abnormalities in the cervical spine, including anterior atlantoaxial subluxation, erosion of the odontoid process, C1 (cid:2) C2 arthritis and apophyseal joint arthritis. Lesions were found even in patients without clinical symptoms and their presence correlated positively with the severity of disease.
