Anatomical terminology [ edit on Wikidata]

The sternocostal joints, also known as sternochondral joints or costosternal articulations, are synovial plane joints of the costal cartilages of the true ribs with the sternum. ^[1] The only exception is the first rib, which has a synchondrosis joint since the cartilage is directly united with the sternum. ^[1] The sternocostal joints are important for thoracic wall mobility. ^[2]

The ligaments connecting them are:

• Articular capsules
• Intraarticular sternocostal ligament
• Radiate sternocostal ligaments
• Costoxiphoid ligaments

Clinical significance

Ankylosis, joint stiffness caused by ossification, may occur at the sternocostal joints. ^[3]

• Costochondritis
