The aim of this study has been to determine the reliability of the digital measurement of the Cobb angle in idiopathic scoliosis (EI) with a computer program (MD) compared with the traditional measurement (MT). To do so, a concordance study was performed by 4 examiners who measured?33 E1 curves whose limits had been predetermined. An MT and MD were performed using the Raim-JAVA digital program, and the measures were repeated one week later.
We found that the intra- and interobserver reliability in both procedures were similar, without significant differences. Measurement errors were lower in the MT than in the MD (7 % vs 8 % ), without statistical differences.
