We investigate the analytical solution for an internal bone remodeling under magnetic field, rotation, porosity and a medullary pin. The model with prescribed boundary conditions has been solved using Lame’s potential method. A new theoretical approach for surface remodeling is thus developed. The components of stresses, stress of the fluid, displacement and rate of internal remodeling are theoretically analyzed and calculated numerically. A movement of the periosteal surfaces and endosteal with remodeling time is displayed considering various values of magnetic field, rotation and bone porosity. The results obtained indicate to the pronounced effect of magnetic field, rotation and porosity on the rate of internal remodeling in bone and agreement with the results obtained previous by others if the rotation and magnetic field have been neglected.
