X-ray lumbosacral spine lateral view showing radiological assessment of structural restoration (Disc height, foraminal height and angle of total lumbar lordosis). Disc height has been measured as (D_A+D_P) / 2; The foraminal height has been measured as the distance between the midpoint of the superior and inferior neural arch (F₁-F₂); The angle of total lumbar lordosis has been measured by the angle formed by the perpendicular lines from the two lines drawn along the superior end plate of L₁ and superior end plate of S₁ (angle ABC)
