Fracture fixation: principles

Contributor(s): Jessica A Kidd-Millar, Jessica A Kidd, Carl Kirker-Head, Jarred Williams

Internal fixation

  • Internal fixation is the use of implants placed deep to the skin and in contact with bone for the purpose of maintaining realignment of previously distracted bone fragments and/or providing sufficient stabilization for healing:
    • Implants can be plates, screws, wires, pins or a combination.
  • External fixation, in contrast, uses methods of support, part or all of which reside outside the skin:
    • Examples include casts, transfixation pins, external fixators, splints.
    • External fixation is generally not as biomechanically strong as internal fixation because of the distant between the fixation method and the bone.
