- Discussion 
    - see adult femoral anteversion
    - w/ flouroscopy obtain a true lateral view of proximal femur in which femoral neck & shaft are parallel but offset about 1 cm;
    - measure the angle referenced from the horizontal;
    - from the true lateral view, one can adjust rotation of the distal fragment in order to achieve femoral neck anteversion of 15 to
             20 deg (or achieve 15-20 deg of internal rotation of epicondylar axis relative to femoral neck);
    - hence, whatever angle the flouroscope requires to superimposed the femoral neck and shaft, the epicondylar axis needs to be internally rotated 20 deg;
    - finally, assess thigh foot angle of uninjured leg and attempt to match this rotation w/ the injured extremity; 
    - Reider Test:
             - prominence of the greater trochanter indicates axis of the femoral neck
