Bones in the Arm

Bones in the Arm
There are three bones in your arm. The upper arm is made up of the humerus bone and the forearm is made up of the ulna and the radius. These three bones meet to form the elbow joint and the radius and ulna join the hand to make the wrist joint, which is known as the carpus.
While it is easy to note that the humerus runs down the arm from the shoulder to the elbow, the radius and ulnar are specific to side either the pinky or thumb side of the wrist. The Radius runs from the elbow joint to the thumb side of the wrist and the ulna from the elbow to the pinky side of the wrist.
When you are diagnosed with a broken arm, it can be one or any combination of all three bones that make up the whole arm. Bone fractures are common in the arms and are usually short-term injuries. They most commonly occur from high-impact collisions such as falls, sports injuries, and automobile accidents. The most common broke bones in the arm are the forearm bones; the radius and the ulna.
While some fractures that are complicated and have multiple breaks may need surgical intervention, the forearm bones are most commonly casted in the proper position to heal a simple fracture. Being that bone is made up of collagen, it is not only strong, but flexible. This is how it is able to take so much force and pressure on a daily basis.
This strength is important considering that most people tend to throw their arms out in front of them to protect them from a fall or accident. Unfortunately, that throwing of the arms is often the cause of a break when falling and is most commonly referred to as FOOSH, or falling on out-stretched hand. Hence the reasons for fractured forearms and in some cases, shoulder injuries or even a broken collar bone.
