"To measure the Cobb angle, one must first decide which vertebrae are the end vertebrae of the curve deformity (the terminal vertebrae) – the vertebra whose endplates are most tilted towards each other 4."
"The Cobb angle was first described in 1948 by American orthopaedic surgeon John R Cobb (1903-1967) 5."
"To measure the Cobb angle, one must first decide which vertebrae are the end vertebrae of the curve deformity (the terminal vertebrae) – the vertebra whose endplates are most tilted towards each other 4."
"In cases where the curvature is not marked, the lines will not intersect on the film/monitor; in this case, two further lines can be plotted, each at right angles to the previous lines 1,4."
"rotation: minor rotation of patients between examinations can significantly change measurements (may be as high as 20° variation); consistent positioning must, therefore, be obtained"
