Abstract:
Total hip arthroplasty (THA) has developed rapidly in recent years, which reconstructs the joint function of some terminal hip joint diseases and obtains favorable efficacy. However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale. This paper analyzed the effects of cement and cementless prosthesis, coated prosthesis, and THA approaches on stress shielding in the proximal femur to reduce stress shielding effect by improving prosthesis design, low elastic modulus materials, decreased section area of the prosthesis, cement prosthesis, appropriate coated materials and improved THA approaches.
