M.6.13 Understanding Bone Fractures and Treatments

Feb 17, 2025

Characterization of Bone Fractures

In this lecture, bone fractures are characterized based on six categories, some of which may overlap:

  1. Location of Fracture

    • Where the fracture occurs in the body.
  2. External Appearance

    • How the fracture appears from the outside.
  3. Type or Nature of the Break

    • The specifics of how the bone is broken.
  4. Position of Bone Ends

    • Non-displaced Fracture: Ends maintain their original position.
    • Displaced Fracture: Ends are out of normal alignment.
  5. Completeness of the Break

    • Complete Break: Bone is broken all the way through.
    • Incomplete Break: Bone is not broken all the way through.
  6. Skin Penetration

    • Open (Compound) Fracture: Bone penetrates the skin.
    • Closed (Simple) Fracture: Skin remains intact.

Common Types of Fractures

  1. Comminuted Fracture

    • Bone fragments into three or more pieces.
    • Common in elderly due to brittle bones.
    • Displaced and complete fracture.
  2. Compression Fracture

    • Bone is crushed.
    • Seen in osteoporotic patients or from extreme trauma (e.g., falls).
  3. Spiral Fracture

    • Caused by torsion or twisting forces.
    • Common in sports.
    • Complete and possibly compound fracture, often displaced.
  4. Epiphyseal Fracture

    • Occurs in adolescents.
    • Cartilage in epiphyseal plate dies off leading to fracture between diaphysis and epiphysis.
  5. Depressed Fracture

    • Typically seen in the skull.
    • Bone or portions of the bone are pushed inward.
  6. Greenstick Fracture

    • Similar to a green twig that bends but does not break completely.
    • Incomplete break with non-displaced ends.
    • Typically a simple fracture.

Treatment of Fractures

  1. Reduction

    • Closed Reduction: Realignment without surgery. Manipulation of bone ends into place.
    • Open Reduction: Surgical intervention using pins and wires to maintain alignment.
  2. Immobilization

    • Depends on the severity, which bone is broken, and patient's age.
    • Casting is a common method to maintain immobility and facilitate healing.
