Abstract: The present paper gives a clear idea of hip joint, it is very complicated structure here we resolve the forces acting on hip joint by using Lami's theorem, by using the geometry from the CT scan the tensile force of ligament and axial compressive forces across the femoral head are obtained at various possible positions of pelvis frame while standing. Analysis is done for a person whose weight varies from 600 N to 1,500 N while standing, it is also extended to finite element analysis, stress distribution and deformation is noticed on the surface of femur. Factor of safety is also obtained.
