Long-term prediction of bone density distribution for retained intramedullary nail

摘要：

　　Intramedullary nailing is a standard treatment for adult long bone fracture.Previous numerous animal,biomechanical and clinical studies have documented the shortterm performance of the intramedullary nails,however,the long-term influence of the nails on the change of bone density distribution is still not fully understood.According to bone remodeling theory,a set of computational algorithms was implemented in the Finite Element model to predict the bone density distribution for retained intramedullary nail.The bone density was recorded to observe the progression of remodeling.The results show that the effect of intramedullary nail on the Gruen zone 4 and 5 of femur is small,while the effect on the Gruen zone 1,2 and 6 is greater than other zones.This simulation indicated that intramedullary nail plays a significant role in the long-term bone density distribution after surgery.
