Common Injuries and Treatments
The elbow joint is the junction between the upper arm bone (humerus) and the forearm bones (radius on the thumb side and ulna on the pinky side). The elbow is a lot like the knee in the lower extremity and its primary motion is bending and straightening. The elbow has a very stable, hard stop of the straightening motion when the end of the humerus fits into the top of the ulna. Bending the elbow is commonly limited by the soft tissue on the front of the arm. The forearm's rotational motion does add a level of movement complexity that allows greater functional range of motion in the wrist and hand, but also allows for more potential injuries at these joints.
