The Ultrasound Perspective for Sternoclavicular Joint in Spondyloarthritis.

Spondyloarthritis (SpA) is a prevalent genetic disorder that significantly impairs mobility, particularly in the spine, sacroiliac, and peripheral joints. Recent evidence highlights early involvement of the sternoclavicular joint in SpA, which may serve as an initial indicator. Diagnosis often relies on CT and MRI, neglecting ultrasound's potential in identifying SpA-related sternoclavicular arthritis. This review focuses on the joint's anatomy, exploring ultrasound's diagnostic and therapeutic role in SpA-related sternoclavicular arthritis, aiming to provide insights for future ultrasound applications in SpA management.
