Fig. 2

a 3D model of the proximal femur from MRI data. (Note the much less precise osseous morphology compared to the CT model shown in Fig. 1). b The same 3D model with the sphere fitted to the femoral head (green), the cross section at the narrowest point of the femoral neck (red) and the femoral neck axis (yellow), connecting the two centers. Both figures were created by the authors using the in-house developed surgical planning software CASPA (Balgrist CARD AG, Zurich, Switzerland)
