BONE FRACTURE

General Information

DEFINITION--

    Complete or incomplete break in a bone. Following are the different types of fractures:

  • Complete fracture. The broken bone is completely separated.
  • Incomplete (greenstick) fracture. The broken bone is not completely separated.
  • Comminuted fracture. There are more than 2 bone fragments at the fracture site.
  • Open fracture (compound). The fractured bone has broken the skin.
  • Closed fracture (including stress fracture). The fractured bone has not broken the skin.
  • Compression fracture. The break occurs from extreme pressure on the bone.
  • Impacted fracture. The broken ends have been driven into each other.
  • Avulsion fracture. Force has been applied to a strong tendon, causing it to pull on and break off a portion of bone.
  • Pathologic fracture. A break that occurs from minor injury in bone weakened or destroyed by disease.
  • Stress fracture. A crack in a bone caused by repetitive and prolonged pressure on the bone, usually by intense exercise.

BODY PARTS INVOLVED--Bones.

SEX OR AGE MOST AFFECTED--Both sexes; all ages.

SIGNS & SYMPTOMS

  • Pain and swelling at the fracture site.
  • Tenderness close to the fracture.
  • Paleness and deformity (sometimes).
  • Loss of pulse below the fracture, usually in an extremity (this is an emergency).
  • Numbness, tingling or paralysis below the fracture (rare; this is an emergency).
  • Bleeding or bruising at the site.
  • Weakness and inability to bear weight.

CAUSES--Injury.

RISK INCREASES WITH

  • Osteoporosis.
  • Tumors of the bone or bone marrow.
  • Activities that carry the risk of injury.
  • Reckless behavior that increases the chance of accidents.
  • Older adults (they tend to fall more and bones are fragile).

HOW TO PREVENT

  • Don't drink alcohol or use mind-altering drugs and drive.
  • Wear protective gear for sports.
  • Use your vehicle's seat belt.
  • If you have osteoporosis, adhere to your treatment program and avoid situations in which injury is likely.

What To Expect

DIAGNOSTIC MEASURES--

  • Your own observation of symptoms.
  • Medical history and exam by a doctor.
  • Laboratory studies to determine blood loss.
  • X-rays of injured parts.

APPROPRIATE HEALTH CARE

  • Almost all fractures require immobilization with casts or splints.
  • Hospitalization for anesthesia and treatment of severe fractures.
  • Surgery, if the fracture must be repaired with rods, plates or screws (see Fracture Repair in Surgery section).
  • Physical therapy for rehabilitation.

POSSIBLE COMPLICATIONS--Failure to heal (non-union), shock from blood loss, travel of a fat embolus (clump of fat cells) from the injury site to the lungs or brain, obstruction of arteries.

PROBABLE OUTCOME-- Usually curable with skillful first aid and aftercare. The broken bone should be manipulated, realigned and immobilized as soon as possible. Realignment is much more difficult after 6 hours.


How To Treat

GENERAL MEASURES----Give first aid treatment for bleeding, cover any open wounds, move patient as little as possible. Then transport to hospital or other emergency facility.

MEDICATION--Your doctor may prescribe: pain relievers, muscle relaxants.

ACTIVITY--

  • Immobility of a bone for a long period can cause loss of muscle bulk, stiffness in nearby joints and edema. It is important to begin to use the affected part as soon as is safely possible.
  • There may be physical therapy with special exercises to maintain flexibility of the joint and strength to the muscles.
  • Resume your normal activities as soon as symptoms improve.

DIET--No special diet. Take vitamin-C and zinc supplements to promote bone healing.


Call Your Doctor If

    The following occurs after immobilization or surgery--Swelling above or below the fracture site, severe, persistent pain, blue or gray skin below the fracture site, especially under nails, numbness or loss of feeling below the fracture site. Report any of the above signs immediately.
