Clavicles are one of the most frequent bones to be broken. Say for example a person falls (and falls are common). It is a natural instinct for a person to extend their arm out in front of them for protection from the fall. When a person stretches their arm out and puts full force on their hand and arm, there is a massive amount of pressure also placed on the shoulder and clavicle. This is one of the reasons that they are broken so frequently. Most of the time when someone breaks their clavicle, it breaks in the middle. These type of fractures usually do not require surgery. Fractures that occur near the joint are more complicated and often require surgery to repair it.

The clavicle is there to support the shoulder, and because of the connection between our upper limbs, and the clavicle it absorbs the majority of the impact in a fall that we break with an outstretched arm.  When most people fall their first instinct is to outstretch their hand to protect their head from hitting the ground.  In doing this the force is transmitted from the point of impact at the hand, up the arm, into the shoulder, and to the joint between the shoulder and the clavicle.  This is when the force ceases travelling and affects the body.  If the force is enough it will break the clavicle.  It isn't so much that it is so easy to break, but that it happens to be in a location that absorbs the impact of the most common way to break a fall - an outstretched arm.
