The hand is a multi-fingered extremity at the end of the arm that plays an essential role of everyday functions. An individual hand is made up of 19 bones that are connected by a series of ligaments. Broken into four segments – fingers, palm, dorsum, and wrist – each part works together to accomplish complex movements.

The hand can be affected by a variety of disorders, most commonly traumatic injuries. Due to the complexity of the bones, tendons, nerves, arteries and ligaments, an injury to the hand needs to be treated by a specialist.
