What is costal cartilage?

Costal cartilage is the cartilaginous structures that connect the ribs to the sternum (breastbone). There are twelve pairs of ribs in the human body, and each rib is attached to the sternum by its own piece of costal cartilage.

This cartilage is composed of hyaline cartilage, a type of flexible connective tissue that is made up of collagen and proteoglycans. Costal cartilage helps to provide flexibility and support to the ribcage, allowing for movement of the chest during breathing and other activities.

While costal cartilage is typically flexible and can withstand a fair amount of stress and strain, it can become damaged or injured in certain circumstances. Common injuries to costal cartilage include fractures, dislocations, and inflammation. These injuries can cause pain, swelling, and difficulty breathing.

Treatment for injuries to costal cartilage typically involves rest, ice, compression, and elevation to reduce swelling and inflammation. In more severe cases, splinting or surgery may be necessary to repair the damaged cartilage.

Overall, costal cartilage plays an important role in supporting the ribcage and allowing for proper chest movement, and proper care and treatment should be taken if any injuries or issues arise.
