Abstract：Objective To compare biomechanical properties of the short-stem prosthesis with conventional prosthesis with the finite element analysis method for the elderly femoral neck fracture after femoral head replace -ment.Methods Three-dimensional finite element models of the upper femur and prosthesis were established .The stress distribution difference between the short-stem prosthesis and conventional prosthesis was compared by using fi-nite element analysis software Ansys 5.7.Results The maximum mises stress of the short-stem prosthesis de-creased significantly,while stress distribution model remained the same .Conclusion The short-stem prosthesis presents superior mechanical properties in femoral head replacement among the elderly femoral neck fractures .
