Sternocostal joints

  (Redirected from Sternocostal)

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]
