Analysis of a Cementless Femoral Stem Neck Fracture Using Scanning Electron Microscopy and the Finite Element Method

Figure 3

Fractured surface observed by macroscopy, digital microscopy, and SEM. (a) Fracture surface observed macroscopically. Arrows indicate the advancing direction of the progressive destruction. (b) Fracture surface observed by digital microscopy. There were multiple micro streaks from the edge of the attachment slot in the stem corner (red arrows). (c) Picture of the fractured surface observed by scanning electron microscopy (~×2000). The basis of the streaks was assumed to be the origin of the fracture. SEM: scanning electron microscope.
