The variability in measurement of the angle of curvature in scoliotic spines was estimated by having 50 anteroposterior roentgenograms read in random order twice by five orthopedic surgeons. The average error was ±9 (±2 SD) on duplicate readings, with a range of ±5° to ±15.1° for individual orthopedists. Difficulty in reproducibly choosing the end vertebrae prior to making the angle measurment appeared to be the major source of measurement error.
