Study Notes
Anatomy
- The clavicle, also known as the collarbone, is a long, slender bone located between the shoulder blade (scapula) and the breastbone (sternum).
- It is a paired bone, with one clavicle on each side of the body.
Functions
- The clavicle serves as a connection between the arm and the body, allowing for a wide range of motion.
- It acts as a strut, providing stability and support to the shoulder joint.
- The clavicle also protects the underlying nerves and blood vessels.
Structure
- The clavicle is a S-shaped bone, with a convex curvature at the lateral (outer) end and a concave curvature at the medial (inner) end.
- It has a rough, porous surface, providing attachment points for muscles and ligaments.
Development
- The clavicle is the first bone to ossify (harden) in the fetus, typically around 5-6 weeks after conception.
- It is formed from two primary ossification centers, which fuse together during childhood.
Clinical Significance
- The clavicle is a common site for fractures, particularly in children and young adults.
- Clavicle fractures can be classified into three types: group I (middle third), group II (lateral third), and group III (medial third).
- The clavicle is also a common site for osteolysis (bone resorption), which can occur due to various conditions such as cancer or infection.
