The fifth metacarpal is one of the five long bones in the hand, specifically located in the palm. It connects the wrist to the little finger, playing a crucial role in hand movement and grip. Each metacarpal bone is numbered from one to five, with the fifth being the outermost bone on the side of the little finger. Injuries to the fifth metacarpal, such as fractures, are common, especially in sports or accidents. These injuries can affect hand function and may require medical attention. Proper treatment is essential for recovery and to restore full use of the hand.
