Distraction osteogenesis and fracture healing : differences and similarities

In experimental research dealing with repair osteogenesis different aspects of its course are stressed. The osteotomy type influences osteoinduction and development of blood vessels, whereas biomechanical features of bone tissue are obtained by proper stabilisation of newly formed callus. Different directions of callus evolution create their final morphology. In this paper, similarities and differences in regenerate and callus morphology are compared in detail.
