Costochondral and Interchondral Joints

Anatomical Location of Costochondral Joints

The costochondral joints are the cartilaginous connections between the ribs and the costal cartilages of the thoracic cage.

Structure and Function

These joints are primary cartilaginous joints, composed of hyaline cartilage, allowing slight movement while providing flexibility and strength to the ribcage.

Clinical Significance

Conditions such as costochondritis, an inflammation of these joints, can lead to chest pain that mimics cardiac symptoms.

Interchondral Joints

Interchondral joints are synovial joints formed between the costal cartilages of ribs, aiding in thoracic expansion during respiration.

• Located between the sixth and ninth costal cartilages.
• Provide elasticity for respiratory movements.
• Can be affected by trauma or degenerative changes.
