A Diagram of Cobb angle measurement in the sagittal plane of the vertebral body. B Diagram for measuring the degree of vertebral compression. UVH (Upper vertebral height) = ( H1 + H2 + H3) / 3. LVH (Lower vertebral height) = ( H7 + H8 + H9) / 3. IVH (Injured vertebra height) = ( H4 + H5 + H6) / 3. VBCR (Vertebral compression ratio) = IVH / [ (UVH + LVH ) / 2 ]
