Hand, Wrist and Elbow Conditions
Your hand is made up of 27 bones. There are 14 small bones in your fingers called the phalanges - three for each finger and two for your thumb. Your wrist is made up of eight bones known as carpals. And your palm contains five bones called the metacarpals. Fractures to the metacarpal bone that leads to your little finger account for about one-third of all hand fractures in adults.
The two bones of your lower arm - your ulna and your radius - meet at the hand to form your wrist.
There are two major nerves in your hand, known as the median and the ulnar nerves. They run the length of your arm to transmit electrical impulses to and from the brain to create movement and sensation in your hand.
