ABSTRACT

To explore the effects of working length on fracture healing, so as to provide the basis for related fracture treatment, the simulation of fracture healing under different working length were conducted using finite element method, and the change in the process of callus growth during healing periods was simulated based on the inter-fragmentary strain theory (IFS). The iterative process for updating callus modulus in every finite element was conducted by the second-developed ABAQUS based on Python code. Results show that the increased working length in a special range could have positive effects on the fracture healing, while exceeding the range would result in a negative effect, so it is a wise choice to choose a suitable working length for fracture healing process.
