主　　题：Cortical bone Fatigue Microdamage Influential factor 

摘      要：Fatigue is a common cause of bone *** the main load-bearing tissue,cortical bone carries a considerable share of load in the whole *** cyclic loading condition,microdamage may generates and accumulates in cortical bone,which further triggers the fracture of *** is crucial to explore the fatigue properties of cortical bone and the influential factors for both clinical diagnosis and establishment of models that can predict fatigue failure of human cortical *** this review,the fatigue behavior of cortical bone was *** the complex hierarchical structure and self-repairing process,the risk of catastrophic fracture is *** on these understandings,the multiple influential factors of cortical bone fatigue properties were analyzed,which were considered to be a combination of internal and external *** internal factors include material properties of bone composition(i.e.,mineral,organic material,and water)and bone *** factors refer to loading condition such as frequency,amplitude and direction of ***,age,disease,radiation exposure and other factors affect the fatigue behavior of bone by altering one or more factors mentioned above.
