Causes
Metacarpal fractures occur more frequently in men. They result from axial forces to the hand, crush injuries, a direct blow or torsion energy. The main causes are:
Sports such as hockey and cricket caused by a direct impact of the bat or hard ball onto the hand
Skiing (thumb metacarpal)
Boxing (little finger metacarpal)
Falls onto fingers/hands in the elderly has almost 50% incidence of all metacarpal fractures
Catching the hand in carpentry machinesĀ
