Femoral Neck Shaft Angle in Men with Fragility Fractures

Figure 1

Measurement of the femoral NSA from the DXA scan printouts. The line AB is the hip axis marked on by the scanner’s software. A line is then drawn from C to D, in which C is the point at which the greater trochanter joins the femoral neck and D is the midpoint of the shaft at the bottom of the picture. The angle 𝛼 is the femoral neck shaft angle.
