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.
