A comparison of traditional protractor versus Oxford Cobbometer radiographic measurement: intraobserver measurement variability for Cobb angles.
STUDY DESIGN: A comparison between measurement of radiographs using a traditional protractor method and the Oxford Cobbometer, which has the potential to reduce error. OBJECTIVE: To assess measurement variability of Cobb angles using the Oxford Cobbometer and to compare it to that of measurements made using the traditional protractor method. SUMMARY OF BACKGROUND DATA: Studies of the Cobb method have multiple sources of error and subsequent intraobserver variability. Estimates of intraobserv...Expand abstract
