Area of Science:

  • Orthopedic Surgery
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Distraction osteogenesis (DO) evolved from G.A. Ilizarov's clinical work and experimental biology.
  • Initially applied for fractures and nonunions, DO is now used for limb lengthening and bone transport.

Purpose of the Study:

  • To describe the history, definition, methods, and monitoring of distraction osteogenesis.
  • To present experimental and clinical data on bone regeneration rates.
  • To propose potential applications in craniofacial surgery.

Main Methods:

  • Review of the historical development and principles of DO.
  • Analysis of experimental data from tibial lengthening in over 125 animals.
  • Evaluation of clinical outcomes in over 100 patients.

Main Results:

  • Distraction osteogenesis facilitates direct bone formation through intramembranous ossification.
  • Experimental data show new bone formation and remodeling at rates of 200-400 microns daily.
  • Clinical studies report average bone regeneration rates of 213 microns/day in adults and 385 microns/day in children.

Conclusions:

  • Distraction osteogenesis is a viable method for significant bone regeneration and lengthening.
  • The technique demonstrates consistent results across various age groups with minimal need for bone grafts.
  • Potential applications of distraction osteogenesis in craniofacial surgery warrant further investigation.
