Calculation of the vertebral height ratio (VHR). A plane approximating the upper endplate (A) was produced automatically by custom-made software (Orthopedic Viewer, Osaka University). The vertebral heights (D and d) were defined as the distances between the two intersection points and the plane. VHR was defined as the ratio of the vertebral height of the concave side to that of the convex side (e.g., the VHR at the anterior = d/D)
