Abstract

Spondyloarthritis (SpA) consists of ankylosing spondylitis, psoriatic arthritis, reactive arthritis, enteropathy-related spondylitis and arthritis, and undifferentiated SpA. It is accompanied by inflammatory back pain and joint symptoms such as oligoarthritis, dactilitis, and enthesitis, which usually occur in the lower extremities. Among these symptoms, enthesitis is an important clinical symptom of SpA because early diagnosis and treatment of enthesitis may improve the prognosis. Therefore, it is important to evaluate objectively the treatment response of enthesitis. Recently, semi-quantitative ultrasonographic evaluation has been used for this purpose by using B-mode images and power Doppler techniques. In this article, I describe the role and application of ultrasonography in the enthesitis of SpA.
