The metacarpus is the part of the hand between the wrist and the fingers. It consists of five long bones known as metacarpal bones, which are numbered one to five starting from the thumb side. These bones make up the palm of the hand and provide structure and support for the fingers.
The metacarpus plays a crucial role in hand function, allowing for fine motor skills such as grasping, gripping, and manipulating objects. The metacarpal bones are connected to the wrist bones on one end and the phalanges (finger bones) on the other end, forming a strong and flexible framework for the hand.
Injuries to the metacarpus, such as fractures or dislocations, can significantly impact hand function and mobility. Treatment for these injuries may involve immobilization, physical therapy, or in severe cases, surgery. Proper care and rehabilitation are essential for ensuring a full recovery and restoring hand function.
