In old age, the costal cartilages are prone to superficial ossification, particularly in women with age of 50 years and over. [3] In costochondritis and Tietze syndrome, inflammation of the costal cartilage occurs. [4] This is a common cause of chest pain. [5] Severe trauma may lead to fracture of the costal cartilage. [6]
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]
It is located approximately 7 cm inferior to the superior margin of the manubrium. [citation needed] The sternal angle is used in the definition of the thoracic plane. [citation needed] The angle also marks the level of a number of features: Boundary between the superior and inferior portion of the mediastinum [citation needed]
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 phrase floating rib (Latin: costae fluctuantes) or vertebral rib refers to the two lowermost (the eleventh and twelfth) rib pairs; so-called because they are attached only to the vertebrae and not to the sternum or any of the costal cartilages. These ribs are relatively small and delicate, and include a cartilaginous tip.
The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the body and xiphoid process of the sternum. [2] The thoracic diaphragm attaches to the costal margin. [3] The costal angle is the angle between the left and right costal margins where they join the sternum. [2]
The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles. On either side of this notch are the right and left clavicular notches. [1] The manubrium joins with the body of the sternum, the clavicles and the cartilages of the first 1.5 pairs of ...
Joints between costal cartilages of the sixth and ninth rib are plane synovial joints. Articulation between costal cartilage of the ninth rib and tenth rib is fibrous. [1] The lateral end of each costal cartilage is received into a depression in the sternal end of the rib, and the two are held together by the periosteum.
