Bone fracture healing is a complex process that involves both biological and mechanical aspects. There are various factors that influence the time period of fracture healing. Over the past decade, many researchers reported the different factors on which the bone fracture healing process depends. These researches also help the orthopedic surgeon to bring the upgradations in their surgical techniques. The type of stability fixation given to the fracture during surgery, the flow of body fluid at the fracture site and direction of interfragmentary motion, i.e., micromotion during the load-bearing period, are some important factors that are discussed by the various researchers in the past. The aim of this review is to highlight the existing knowledge about the biology of bone fracture repair, the recent research on bone fracture and the effect of biological and mechanical aspects on the bone fracture healing process.
