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 prominent knobs of bone at the costochondral joints of rickets patients are known as a rachitic rosary or beading of the ribs.The knobs create the appearance of large beads under the skin of the rib cage, hence the name by analogy with the beads of a Catholic Christian rosary.
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] The ligaments connecting them are: Articular capsules; Intraarticular sternocostal ligament; Radiate sternocostal ligaments; Costoxiphoid ligaments
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. [2] Like the ribs, the costal cartilages vary in their length, breadth, and direction. They increase in length from ...
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 articulations of the heads of the ribs (or costocentral articulations) constitute a series of gliding or arthrodial joints, and are formed by the articulation of the heads of the typical ribs with the costal facets on the contiguous margins of the bodies of the thoracic vertebrae and with the intervertebral discs between them; the first, eleventh and twelfth ribs each articulate with a ...
