The Hand, Wrist, and Elbow
Fractures of the hand can occur in either the small bones of the fingers (phalanges) or the long bones (metacarpals). They can result from a twisting injury, a fall, a crush injury, or direct contact in sports.
The scaphoid is one of the small bones in the wrist. It is the wrist bone that is most likely to break. The scaphoid is located on the thumb side of the wrist, in the area where the wrist bends.
When you bend your elbow, you can easily feel its "tip," a bony prominence that extends from one of the lower arm bones (the ulna). That tip is called the olecranon. It is positioned directly under the skin of the elbow, without much protection from muscles or other soft tissues. It can easily break if you suffer a direct blow to the elbow or fall on a bent elbow.
