摘要：
A data processing method, performed by a computer, for determining a leg length difference and a leg offset difference of a patients leg including a femur connected to a pelvis, comprising the steps of: —determining a first landmark vector between a femoral landmark and a second landmark at a first point in time —determining a second landmark vector between the femoral landmark and the second landmark at a second point in time which is later than the first point in time —calculating an orthogonal projection of the first landmark vector into a sagittal plane and using the direction of the orthogonal projection of the first landmark vector into the sagittal plane as a leg length direction —calculating a direction which is perpendicular to the sagittal plane and using this direction as a leg offset direction and —calculating the leg length difference in the leg length direction and the leg offset difference in the leg offset direction from the first landmark vector and the second landmark vector.
