Anatomy of Clavicle

Updated: Jun 9, 2020

The clavicle is a snake shaped bone that is located near the neck region. It is on the anterior side (front side) of our bodies. We have a right and a left clavicle that poke out more medially and "dip" posteriorly as one follows laterally (from the center of your body the clavicle pokes out and then dips back in as you move towards the outside of your body).

The clavicle articulates with the scapula to make the acromioclavicular joint. The acromion of the scapula and the acromial end of the clavicle meet together to make this joint.

A common injury that can be seen with the AC joint is in baseball or softball players. When an athlete dives to catch a ball, has their arm flexed and elbow extended, (stretched in front of them) and lands with enough force, the AC joint can POP out of place.

Check out this video on the clavicle and the resources below:

The arrows indicate structures underneath or on the inferior portion of the clavicle. The dots indicate a rough patch.

1. Acromial End (or distal or lateral)

2. Costal Tuberosity

3. Sternal End

4. Conoid Tubercle

Think of the costal tuberosity being on the sternal end. They both have "st" in their name.
