Objective To investigate the initiation of fracture repair and regulation on molecular level.Methods Literature concernedfracture repair and effects of correlative factors in the process in recent years was reviewed. The initiation in the process of fracture repair and the effects of the correlative factor were summarized to probe into effective methods to intervene. Results During fracture repair, the initiation had particular character and the correlative factors were concerned with the process. Conclusion The correlative factors regulate the initiation of fracture repair on molecular level.
