From: Evaluation of an objective staging system for assessment of cervical vertebral maturation
Objective staging system outcomes: (A) concavity depth (CD), the linear perpendicular distance from point Cd (most superior point of the inferior border of the body) to CL (the lower border) at C2, C3 and C4; (B) Body Shape, the ratio of Body width (BW) to Body height (BH) of C3 and C4; (C) Superior Wall Inclination Angle (SWIA), the angle between superior border (CS) and posterior border (CP) of C3 and C4
