Clavicle

Os claviculae

The clavicle extends horizontally from the sternum to the acromion of the scapula. It is the first bone to ossify (by intramembranous ossification) and the last to complete ossification. The medial two-thirds are convex anteriorly, while the lateral third is concave.

Type Bone
Body System Skeletal
Body Region Shoulder
Latin Name Os claviculae
FMA ID 13321

Function

A slender S-shaped bone that forms the anterior part of the shoulder girdle. Acts as a strut to keep the upper limb away from the trunk, allowing free movement. Transmits forces from the upper limb to the axial skeleton.

Clinical Significance

The clavicle is the most commonly fractured bone, typically at the junction of the middle and lateral thirds. Clavicle fractures can injure the subclavian vessels or brachial plexus. Sternoclavicular joint dislocations are uncommon but potentially dangerous.
