A bone fracture is a break in a bone. The soft tissue surrounding the
break may also be injured. Most bone fractures are the result of injuries
from falls or vehicle crashes, but fractures can also be caused by certain
diseases. The May 5, 2004, issue of JAMA includes
an article about external fixation (see below) to
treat bone fractures.
Injuries from falls, sports, or vehicle crashes
Osteoporosis—weakening of the bones associated
Tumors that grow on or near bones
Prolonged walking or running—sometimes called
Simple—the bone is broken in one place.
Comminuted—the bone is broken in several
places with at least 3 bone fragments.
Open—the skin is injured exposing the broken
bone (also called "compound").
Closed—the skin is intact over the broken
Undisplaced—the broken bone pieces are aligned.
Displaced—the broken bone pieces are not
If you think you have broken a bone, seek emergency
medical care immediately.
A medical examination and x-rays can help determine
if and where a bone is broken.
The broken pieces may need to be put back in place
and then immobilized until the bones can heal as new bone forms around the
The type of treatment will depend on the kind of
fracture and the specific bones involved.
Fractured bones usually need at least 4 weeks to
heal although casts may be removed before that to prevent stiffness (particularly
for fractures involving the elbow or hand).
Physical therapy may be required after the bone
Casting—After the broken bones have been
manipulated back into their proper positions, a plaster or fiberglass cast
is applied to keep the bones from moving while they heal.
External fixation—Pins or wires are set into
the bone through the skin above and below the fracture. These are connected
to a ring or a bar outside the skin that holds the pins in place. After the
bones have healed, the pins are removed.
Internal fixation—In a surgical procedure,
metal rods, wires, or screws are inserted in the bone fragments to keep them
