Fall and osteoporotic fractures

Fall is an interaction result of internal and external factors of the body in the old people.Fall is happened frequently in senile persons,it's an important figure of aging.A low energy injury induced fracture happens will be often belonged to osteoporotic fracture,which is also named as fragile fracture.Occurrence of fragile fracture means the decline of bone structure and exhaustion of bone function.Health condition,accompanied diseases,genetic factors,mental and psychological status,behaviors and living environments,gait steady,as well as drugs intake are all the risk factors of fall in aged persons.About 9%of all old people will suffer the fractures after fall.Besides the intervention of external stress force,the bone mineral density and bone quality reduced are also lead to the bone mechanical strength weakness; this is also a key factor of osteoporotic fracture.Some diseases suffered and drugs intake could affect the bone mineral density and bone quality,height of a person,BMI,nutrition situation,gonadal function,VitD insufficienay and prior-fracture history are significant factors for predicting the risks of fragile fractures.A lot of tool for predicting the risks of fall or fragile fracture,FRAX is the most common used method all of the world,which is recommended by WHO as well.Analysis of risk factors will be helpful to identify the individuals who are under the high risk of fall or fragile fracture.The fall and fracture accident of senile people will decline,if the risk factors could be prevent and intervene.It is the most efficient way that has been proved in practice.To improve the analysis system of risk factors individually,monitoring and formulating the intervention process will be effective to reach the target for reducing the falls and fractures in senile persons.
