Figure 3 Application of the Greater Trochanter Orthogonal Line: An orthogonal line perpendicular to the anatomical axis of the femur and passing through the level of the tip of the greater trochanter indicates its relative height to the femoral head, which is divided into four zones. A: The relative height postoperatively; B: Comparison with the contralateral healthy side.
