clavicle anatomy


The clavicles, also know as collarbones, are a pair of long bones that connect the scapula to the sternum. The clavicle is one of the most commonly broken bones in the human body. It also serves as an important and easily located bony landmark due to its superficial location and projection from the trunk. It receives its name from the Latin: clavicula (“little key”) because the bone rotates along its axis like a key when the shoulder is abducted.

The functions of the clavicles is to hold the arms freely and supported, away from the trunk; Covering the cervicoaxillary canal, it protects the neurovascular bundle that supplies the upper limb and Transmits physical impacts from the upper limb to the axial skeleton.

Fractures of the clavicles are common. A fracture is easy to detect because the clavicle lies directly under the skin, making any deformity immediately visible. Symptoms of a fractured clavicle include an inability to move the arm because of pain and tenderness, swelling.
