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 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 sternal angle marks the point at which the costal cartilage of either second rib articulates with the sternum. During physical examinations, the readily palpated sternal angle is thus used as a landmark to identify the 2nd rib, and by extension, by counting, also the remaining ribs. Meanwhile, the first rib cannot be used for this purpose ...
The lateral borders are each marked above by a depression for the first costal cartilage, and below by a small facet, which, with a similar facet on the upper angle of the body, forms a notch for the reception of the costal cartilage of the second rib. Between the depression for the first costal cartilage and the demi-facet for the second is a ...
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.
Costal may refer to: an adjective related to the rib (Latin: costa) in anatomy Costal cartilage, a type of cartilage forming bars which serve to prolong the ribs forward; Costal margin, the medial margin formed by the false ribs; Costal surface (disambiguation) Costal groove, a groove between the ridge of the internal surface of the rib
Anatomy of the costal cartilage. Costochondritis typically presents unilaterally (one side), which is typically the left side. [4] It affects primarily the 2nd to 5th ribs at the sternocostal and costochondral joints. [1] The most commonly reported symptom of costochondritis is chest pain that is often exacerbated by movement and deep breathing.
Structure [ edit ] It passes obliquely upward, forward, and to the right, in the direction of the heart's axis, as high as the upper border of the second right costal cartilage , describing a slight curve in its course, and being situated, about 6 centimetres (2.4 in) behind the posterior surface of the sternum .
