principles of fracture fixation

  1. 1. + Principles of fracture fixation
  2. 2. + Absolute stability No micromotion in the fracture  healing by primary (direct) bone without callus formation
  3. 3. + Relative stability There is some motion in the fracture fragments  stimulation of callus formation  secondary bone healing by callus formation
  4. 4. + Perren's strain theory
  5. 5. + Fracture Simple fracture (<2 mm) Multifragmentary (>2 mm) Relative stability Bone resorption, healing delay, or nonunion Secondary bone healing (callus) Absolute stability Primary bone healing, osteonal remodelling Bone resorption, healing delay, or nonunion
  6. 6. + Methods of absolute stability Compression by Lag Screw
  7. 7. + Compression plate
  8. 8. + Dynamic compression by Tension band
  9. 9. + Methods of relative stability Bridging plate
  10. 10. + intramedullary nailing
  11. 11. + External fixation
  12. 12. + Home message  Simple diaphysialfracture anatomical reduction and absolute stabilization  Intraarticular fracture  anatomic congruity of the joint surface must be restored and the fragments should be fixed rigidly by interfragmentary compression  Diaphysialmultifragmentaryfracture god alignment in all planes and relative stabilization.
