The present work was aimed at understanding the stress-shielding caused by hip-joint implantation into a femur by using a human cadaver with a cementless hip implant. In particular, bone quality was assessed from the standpoint of preferential c-axis orientation of biological apatite (BAp). Comparing the implanted side to the non-implanted side, a finite element analysis (FEA) indicated that artificial hip-joint implantation had a significant stress-shielding on the femur. The results also showed a remarkable decrease in the degree of preferential BAp orientation as well as bone loss in Haversial canal in the medial-proximal femur. This is the first report showing a reduction in the degree of preferential BAp orientation due to a stress-shielding after artificial hip-joint implantation. Since preferential BAp orientation is an important parameter for determining bone mechanical function, these findings should be taken into account in future artificial hip-joint designs, especially those involving the stem component.<br>
