Abstract:
0.05).[Conclusion]1.It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation.After using CFR/PSF of lower elastic modulus as handle,the stress dodge rate is lower in femur,but the interface stress is higher,and this is the main factor and reason for the prosthesis loosening.2.The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal.The stress value in different combination of same prosthesis handle has no significant difference,that showes mechanical factor is not the main standard for selecting prosthesis combination.
