Fractures of the Palm
Introduction
Fractures of the palm involve the bones located between the finger bones and wrist bones. These bones are called metacarpal bones. Occasionally, the metacarpal bone at the base of the thumb fractures, but these fractures are usually considered separately. Metacarpal fractures often result from punching a hard object. The knuckles are swollen and tender. Usually, doctors can diagnose these fractures based on x-rays taken from several angles. Treatment involves a splint and sometimes first putting the broken pieces of bone back in place (reduction), depending on the type of fracture. (See also Overview of Fractures .) Metacarpal fractures are often called boxer's fractures because they often result from punching a hard object (such as a wall or another person's jaw). When these fractures result from punching someone in the mouth, the skin may be broken ( Hand Infections Caused By Bites ). In such cases, bacteria from the other person's mouth can contaminate the wound and cause infections that, if not treated soon, can permanently affect use of the hand.
