WebNov 17, 2024 · The main mechanical factor that causes loosening of cementless hip prostheses is stress shielding. Naturally, when a load is applied to the intact femoral head, stress is transmitted through the trabecular bone of the femoral neck to the cortical bone of the proximal femur. Web- stress shielding is the redistribution of load (and consequently stress onthe bone) that occurs when the femoral head is replaced by the femoral component of a total hip replacement; - stress on proximal 10 cm of femoral cortex is reduced, because much of the load bypasses this region and is carried in the metal stem to the isthmus of the femur;
