Clavicle

Anatomy:
The clavicle (collarbone) extends between the manubrium of the sternum and the acromion of the scapula. It is classed as a long bone and can be palpated along its length. In thin individuals, it is visible under the skin.

Innervation:
The intermedial supraclavicular nerve middle supraclavicular nerves (nn. supraclaviculares medii; supraclavicular nerves) cross the clavicle, and supply the skin over the pectoralis major and deltoideus, communicating with the cutaneous branches of the upper intercostal nerves.

Vasculature:
The subclavian artery and vein, and the divisions of the brachial plexus, lie posterior to the medial curvature of the clavicle and pass beneath the middle third of the clavicle where the divisions branch into cords and the subclavian vessels become the axillary vessels.

Possible Effects of a Strike:
  • paralysis of arm
  • perforation of the lungs
