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 first seven pairs are connected with the sternum; the next three are each articulated with the lower border of the cartilage of the preceding rib; the last two have pointed extremities, which end in the wall of the abdomen.
The costochondral joints are the joints between the ribs and costal cartilage in the front of the rib cage. They are hyaline cartilaginous joints (i.e. synchondrosis or primary cartilagenous joint). Each rib has a depression shaped like a cup that the costal cartilage articulates with. There is normally no movement at these joints.
The intraarticular sternocostal ligament is a horizontal fibrocartilaginous plate in the center of the second sternocostal joint. It connects the tip of the costal cartilage to the fibrous junction between the manubrium and the body of the sternum , dividing the joint into two parts.
Costochondritis, also known as chest wall pain syndrome or costosternal syndrome, is a benign inflammation of the upper costochondral (rib to cartilage) and sternocostal (cartilage to sternum) joints. 90% of patients are affected in multiple ribs on a single side, typically at the 2nd to 5th ribs.

The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.

Anatomy of the rib cage. The presentation of slipping rib syndrome varies for each individual and can present at one or both sides of the rib cage, with symptoms appearing primarily in the abdomen and back. [3] Pain is most commonly presented as episodic and varies from a minor nuisance to severely impacting quality of life.
