Bones in the Human Hand

10. Injuries

Injuries to bones and joints in the hand are common because so many fragile bones reside under a thin layer of skin and muscle. Hands are constantly in motion, performing the tasks of daily living. There are many more joints in the hand than any other part of the body, so they are also susceptible to arthritis. The most common injuries are sprains affecting the wrist, fractures of individual bones, and dislocation of phalanges.
