Histopathological Finding of Microdamage Accumulation in Atypical Subtrochanteric Femoral Fracture

Figure 1

Radiographs of both femurs. The initial right femoral plain radiograph shows an atypical subtrochanteric fracture (a). On the contralateral side, no fracture is detected at the subtrochanteric site (b). The intramedullary nail is inserted during primary surgery with osteosynthesis (c). The intertrochanteric screw is broken (white arrow) (d), and the fracture site is more displaced than that shown in (c). Revision surgery is then performed. The intramedullary nail is reinserted, and the lag screw is inserted in the femoral neck and head (e).
