Injuries to metacarpal bones
 

Metacarpal bones are five in number and are named from lateral to medial

    Metacarpal I

    Metacarpal II

    Metacarpal III

    Metacarpal IV

    Metacarpal V

They are placed distal to the carpal bones, and articulate with the distal row; i.e. trapezium, trapezoid, capitate and hamate. They help to form the endoskeleton of the hand as opposed to that of the digits which is formed by the phalanges
