Which peripheral joints are most commonly involved in Axial Spondyloarthritis?
Approximately 30% of patients with axSpA develop a peripheral arthritis. The hips and shoulders (girdle joints) are involved most commonly. Notably, hip involvement in axSpA is associated with a poor prognosis.
Rarely, arthritis of the sternoclavicular, temporomandibular, cricoarytenoid, or symphysis pubis occurs. Involvement of the thoracic costovertebral, sternocostal, and manubriosternal joints may cause chest pain worsened by coughing or sneezing.
