Objective:
To evaluate the intra and inter observer agreement of the Sauvegrain, Greulich and Pyle methods.
Material And Methods:
This is an observational, retrospective and cross-sectional study ethically approved by opinion 6,192,391. 100 radiographic images of the elbow and 100 of the left wrist and hand were collected from children whose images were selected by a researcher who did not carry out the evaluations. The Sauvegrain, Greulich and Pyle methods were used to determine bone age. We provided a detailed explanation of each method and the evaluators received a file with the study images. After three weeks, the exams were randomized and the radiograms were reevaluated. Of the 100 patients in group A, 61 (61%) were boys and 39 (39%) were girls. In group B, 67 (67%) were boys and 33 (33%) were girls.
Four Statistical Analyzes Were Used:
correlation; intraclass correlation; analysis using the Bland-Altman graph; differences between groups.
Results:
Intra and interobserver agreement between groups was considered excellent.
Conclusions:
Despite the excellent agreement, group A presented a significantly better value than B. Biological ages show a greater difference compared to chronological ages in group A. In group B, skeletal and chronological ages do not show statistical difference according to the accuracy test.
