A direct blow or crushing injury to your hands and wrists can break any of the bones in them. Common causes include:

  • Falls. Falling onto an outstretched hand is one of the most common causes of a broken wrist or broken hand.
  • Sports injuries. Many wrist or hand fractures occur during contact sports or sports in which you might fall onto an outstretched hand — such as in-line skating or snowboarding.
  • Motor vehicle crashes. High-velocity injuries that can occur during motor vehicle crashes may cause wrist or hand bones to fracture into many pieces, often requiring surgical repair.
