Anatomy of the Clavicle

credit:https://www.theskeletalsystem.net/arm-bones/clavicle-collarbone.html

The clavicle is a long bone that extends from the manubrium of the sternum to the acromion of the scapula

Ligaments:

- Costoclavicular ligament

- Coracoclavicular ligament

Muscles:

The shaft of the clavicle is an attachment point for many muscles including:

- deltoid, trapezius, subclavius, pectoralis major, sternocleidomastoid and sternohyoid

Clavicle fractures:

- Most common MOI: FOOSH or fall on shoulder

- 15% of clavicle fractures occur in lateral third, 80% in middle third, and 5% in medial third.

- With operative management, the supraclavicular nerves may be damaged and result in numbness over the upper chest and shoulder.
