Overview
This article describes a method for stabilizing long bone fractures using modified Ilizarov external fixators. The procedure allows for the assessment of healing, distraction osteogenesis, and the creation of non-union or critical sized defects for therapeutic studies.

What is the purpose of using Ilizarov fixators?
Ilizarov fixators are used to stabilize long bone fractures and facilitate healing processes.
How is distraction osteogenesis performed?
Distraction osteogenesis is performed by gradually separating bone segments to promote new bone formation.
What analyses are used to assess healing?
Healing is assessed using x-ray, histologic, and molecular analyses.
Who conducted the study?
The study was conducted by Dr. Diane, Y Yuu, and Dr. Chelsea Baney from UCSF.
What are the potential applications of this method?
This method can be used for studying therapeutic interventions for bone defects and improving fracture healing.
Can this model be used for other types of bone injuries?
Yes, the model can be adapted for various bone injuries and healing studies.
