four models in the coronal view under the loading condition of walking are
shown in Fig. 8.16. The maximum upper limit is 654 MPa. Therefore, 0–654
MPa was used as the range to display the stress distribution. In the fractured
femur with implanted PFNA, little stress concentration was observed near
the locking bolt, whereas, it was obvious that stress concentration appeared
when the fracture was healed.
Stress distributions in the proximal femur are different in the process
of healing. The higher stress on the proximal femoral neck region, at the
interface of nail and blade ...
