%X Hip prosthesisis frequently used in the treatment of femoral head fractures. Material properties and the prosthetic attachment of the bone cells greatly influence the biomechanical behavior of the prosthesis because of differences in the design of the prosthesis. In this study, the design of the hip prosthesis used in femoral bone fractures was carried out in a different porous structure. In addition, finite element analyses were performed taking into account the mechanical properties of the bone according to the healing weeks. For this purpose, a two-piece hip prosthesis was designed. Lower part of prosthesis was modeled with two different porous structures with three different dense using SolidWorks 2018 software. Effective elasticity modulus was calculated taking into consideration of the mechanical properties of the hip prosthesis material and the callus structures which were formed during different healing periods.Then, according to the results obtained, the hip prosthesis was mounted on the thigh bone. The obtained models were analyzed using ANSYS 18.0 software under axial force of 1000N.As a result of the analyzes; since porous structures were used in the hip prosthesis, lower stresses in the hip prosthesis were observed.Also, it was concluded that differences on callus structure is an essential parameter that affects mechanical properties of bone-prosthesis structure
