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]
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.
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
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 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 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.
Semi-transparent and non-porous, it is usually covered by a tough and fibrous membrane called perichondrium. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, [1] and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs.
The costal part of diaphragm arises from the lower four ribs (7 to 10) costal cartilages. [8] The central tendon of the diaphragm is a thin but strong aponeurosis near the center of the vault formed by the muscle, closer to the front than to the back of the thorax. The central part of the tendon is attached above to pericardium. The both sides ...
