The sternum, also known as the breastbone, is a vital part of the human anatomy. Understanding the structure and function of the sternum is essential for grasping its significance in supporting the upper body and protecting vital organs. Additionally, being aware of common sternum injuries and their treatments is crucial for maintaining overall well-being. Let’s delve into this comprehensive guide to the sternum, covering its anatomy, functions, as well as the management of common injuries. This “Sternum guide” aims to provide valuable insights into this often overlooked yet critical part of the human body.
The Structure and Function of the Sternum
The sternum, also known as the breastbone, is a flat bone located in the center of the chest. It consists of three parts: the manubrium, the body, and the xiphoid process. The sternum plays a crucial role in protecting the vital organs in the chest, including the heart and lungs. Its primary functions include:
- Protection: The sternum provides a shield for the vital thoracic organs, safeguarding them from external trauma.
- Attachment: It serves as an attachment site for the clavicles and ribs, allowing for the articulation of the upper limbs and the protection of the thoracic cavity.
- Hematopoiesis: The bone marrow within the sternum is involved in the production of red blood cells, white blood cells, and platelets, contributing to the body’s immune function.
Understanding the structure and function of the sternum is essential for recognizing its importance in maintaining overall health and well-being.
In the table below, you can see a comparison of the three parts of the sternum:
| Part | Location | Function |
|---|---|---|
| Manubrium | Upper portion | Articulates with the clavicles and first rib |
| Body | Middle portion | Articulates with the costal cartilages of ribs |
| Xiphoid Process | Lower portion | Attachment site for some abdominal muscles |
Remember, a well-maintained sternum is crucial for overall health and physical well-being.

Common Sternum Injuries and Treatment
The sternum is a vital part of the human body, but it is susceptible to various types of injuries. Here’s a brief overview of common sternum injuries and their treatments:
- Fractures: Sternum fractures can occur due to direct trauma, such as from a car accident or a sports injury. Treatment usually involves rest, pain management, and in severe cases, surgical intervention.
- Costal Cartilage Injuries: The costal cartilage connecting the rib to the sternum can be strained or torn, causing sharp pain. Treatment typically involves rest, ice, and anti-inflammatory medications.
- Contusions: Sternum contusions, often seen in contact sports, result from a direct blow to the chest. Treatment includes rest, ice packs, and over-the-counter pain relievers.
- Treatment Options: In most cases, sternum injuries are managed with conservative treatments, but severe fractures might require surgery to realign and stabilize the bone.
Remember, if you suspect a sternum injury, it’s crucial to seek medical attention for a proper diagnosis and treatment plan.
