Metacarpals

The metacarpalsare long bones within the hand that are connected to the carpals, or wristbones, and to the phalanges, or finger bones. The metacarpals together arereferred to as the "metacarpus."The tops of the metacarpals form the knuckles where they join to the wrist. Onthe palm side, they are covered with connective tissue. You can feel and seethe metacarpals on the back of your hand, through your skin. The fivemetacarpals are called thumb metacarpal,index metacarpal, middle metacarpal, ring metacarpal, and small metacarpal.Ten percent of all fractures that occur are those to the metacarpals andphalanges, the most common injuries being from car accidents, sports injuries,and work-related injuries. The goal in repairing these injuries is to do sowhile maintaining strength of hand grip and no residual pain upon using thehand. Boxers tend to have high incidence of fracture to metacarpals, hence theterm "Boxers Fracture."
