Fractures…
"Thank
goodness it's only a fracture. I thought it might be broken."
People often think that a fracture is less severe than a
broken bone, but fractures are broken bones.
To
understand why bones break, it helps to know what bones
do and what they are made of. The bones of the body form
the human frame, or skeleton, which supports and protects
the softer parts of the body. Bones are living tissue. They
grow rapidly during one's early years, and renew themselves
when they are broken.
Bones
have a center called the marrow, which is softer than the
outer part of the bone. Bone marrow has cells that develop
into red blood cells that carry oxygen to all parts of the
body and into white blood cells that help fight disease.
Bones also contain the minerals calcium and phosphorus.
These minerals are combined in a crystal-like or latticework
structure. Because of their unique structure, bones can
bear large amounts of weight.
How
Fractures Occur
Bones are rigid, but they do bend, or "give" somewhat
when an outside force is applied to them. When this force
stops, bone returns to its original shape. For example,
if you fall forward and land on your outstretched hand,
there's an impact on the bones and connective tissue of
your wrist as you hit the ground. The bones of the hand,
wrist and arm can usually absorb this shock by giving slightly
and then returning to their original shape and position.
If the force is too great, however, bones will break, just
as a plastic ruler breaks after being bent too far.
Types
Of Fractures
The severity of a fracture usually depends on the force
that caused the fracture. If the bone's breaking point has
been exceeded only slightly, then the bone may crack rather
than breaking all the way through. If the force is extreme,
such as in an automobile collision or a gunshot, the bone
may shatter. If the bone breaks in such a way that bone
fragments stick out through the skin or a wound penetrates
down to the broken bone, the fracture is called an "open"
fracture. This type of fracture is particularly serious
because once the skin is broken, infection in both the wound
and the bone can occur.
Treating
Your Fracture
Because fractures hurt and make it difficult if not impossible
to use the part of the body that is injured, most people
call a doctor or seek emergency care quickly. In some cases,
however, a person can walk on a fractured bone in the leg
or foot, or use a fractured arm. Just because you can use
your hand or foot does not mean that you do not have a fracture.
If you think a bone may be broken, you should seek medical
help immediately. A medical examination and x-rays are usually
necessary to tell for sure and to ensure proper treatment.
It
is very important to control the movement of a broken bone.
Moving a broken or dislocated bone can cause additional
damage to the bone, nearby blood vessels, and nerves or
other tissues surrounding the bone. That's why people giving
first aid or emergency treatment may splint or brace your
injury before medical treatment is given. Also, if there
is an open wound it should be covered by a clean cloth or
bandage on the way to further medical treatment.
At
the emergency room, clinic or doctor's office, the physician
usually applies a splint to prevent further damage, to lessen
the pain and to help stop any bleeding. The patient is usually
asked to recline and elevate the injured part. Elevation
helps to reduce bleeding and swelling.
X-rays
can help the physician determine whether there is a fracture,
and if so, what type of fracture it is. If there is a fracture,
the doctor will "reduce" it, by restoring the
parts of the broken bone to their original positions. "Reduction"
is the technical term for this process.
All
forms of treatment of broken bones follow one basic rule:
the broken pieces must be put back into position and prevented
from moving out of place until they are healed. Broken bone
ends heal by "knitting" back together with new
bone being formed around the edge of the broken parts. The
specific method of treatment depends on:
- The
severity of the break.
- Whether
it is "open" or "closed."
- The
specific bone involved-a broken bone in the spine (vertebra)
is treated differently from a broken leg bone or a broken
rib.
Types
Of Treatment
The following treatments are used for various types of fractures.
Cast Immobilization – A plaster
or fiberglass cast is the most common type of fracture
treatment, because most broken bones can heal successfully
once they have been repositioned and a cast has been applied
to keep the broken ends in proper position while they
heal.
Functional
Cast or Brace – The cast or brace allows
limited or "controlled" movement of nearby joints.
This treatment is desirable for some but not all fractures.
Traction
– Traction is usually used to align a bone or bones
by a gentle, steady pulling action. The pulling force
may be transmitted to the bone through skin tapes or a
metal pin through a bone. Traction may be used as a preliminary
treatment, before other forms of treatment.
Open
Reduction and Internal Fixation – In this
type of treatment, an orthopedist must perform surgery
on the bone. During this operation, the bone fragments
are first repositioned (reduced) into their normal alignment,
and then held together with special screws or by attaching
metal plates to the outer surface of the bone. The fragments
may also be held together by inserting rods down through
the marrow space in the center of the bone. These methods
of treatment can reposition the fracture fragments very
exactly. Because of the risks of surgery, however, and
possible complications, such as infection, they are used
only when the orthopedic surgeon considers such treatment
to be the most likely to restore the broken bone to normal
function.
External
Fixation – In this type of treatment, pins
or screws are placed into the broken bone above and below
the fracture site. Then the orthopaedic surgeon repositions
the bone fragments. The pins or screws are connected to
a metal bar or bars outside the skin. This device is a
stabilizing frame that holds the bones in the proper position
so they can heal. After an appropriate period of time,
the external fixation device is removed.
Each
of these treatment methods can lead to a completely healed,
well-aligned bone that functions well. Remember that the
method of treatment depends on the type and location of
the fracture, the seriousness of the injury, the condition
and needs of the patient, and the judgment of the orthopedist
and the patient.
Successful
treatment of a fracture also depends greatly on the patient's
cooperation. A cast or fixation device may be inconvenient
and cumbersome, but without one a broken bone can't heal
properly. The result may be a painful or poorly functioning
bone or joint. Exercises during the healing process and
after the bone heals are essential to help restore normal
muscle strength, joint motion and flexibility. Help your
broken bone heal properly-follow your orthopedist's advice.
Preventing
Broken Bones
Even though healthy bones are very strong, any bone will
break if the force applied against it is great enough. Bones
that are weakened by disease or misuse may break more easily
than healthy bones. To develop and maintain healthy bones,
a person needs adequate amounts of calcium and proper exercise.
Because
of the way bones are made, calcium is very important in
the growth, development, and maintenance of strong bones.
Adequate amounts of calcium are necessary as a child grows
and for the adult as well. Women, in particular, must have
enough calcium in their diet. The female hormone estrogen
regulates the use of calcium in women's bodies. Following
menopause, when women produce far less estrogen, calcium
regulation is more difficult. So it is very important that
women make their bones as strong as possible before menopause,
through weight-beating exercise and adequate calcium in
their diets. In some women after menopause, bones fracture
very easily because they have been weakened by calcium depletion.
Because
of the way bones are made, they also get stronger with regular
but not excessive exercise. If a person is active, bones
will become stronger and more dense. The bones of an inactive
person are often not as strong and may fracture more easily
than those of an active person. For this reason, older people
should try to remain physically active.
Proper
diet and exercise, along with an understanding of what bones
are made of and how they break, may help in preventing some
fractures. If you do break a bone, seek medical treatment.
