Interchondral joints

The interchondral joints are small articulations between the apposed costal cartilages of the ribs 7-10.

On each side are three diminutive synovial joints between the surfaces of the 6th and 7th costal cartilages, 7th and 8th costal cartilages and 8th and 9th costal cartilages. The 9th and 10th costal cartilages are interconnected by tough ligamental bands, the intercostal ligaments, these also join together the costal cartilages of ribs 6, 7, 8 and 9 .
