Why should the femoral neck fracture be reduced anatomically?

Why should the femoral neck fracture be reduced anatomically?

Because in this position remaining vascular supply of the femoral head after a fracture is best preserved and the revascularisation of the head of femur is best facilitated.
Furthermore primary bone healing of a femoral neck fracture only occurs with anatomic alignment of the fracture ends with a maximum width of the gap of maximal 1mm.
No osteosynthesis will survive an inadequate reduction of a femoral neck fracture.
