Fracture healing

Abstract

Fracture healing, an extremely complicated and also a perfect process, has been successfully attracting man’s attention for many years. Although a great number of mechanisms regarding the process have been figured out, much still remains unknown. Fracture healing is a unique process like no other, which develops without the formation of fibrous scar tissue and can be defined as the regeneration of a variety of tissues. To obtain full functional bone regeneration, it is necessary to progress of anatomical, biochemical, and biomechanical processes with excellent compatibility. In recent years, mesenchymal stem cells and many molecular and chemical pathways which have an important role in bone repair have been well defined. However, fracture repair continues to be an equation with several unknowns.
