“…Also, children were grouped according to chronological age, not bone age, which may partially affect the results. 36 The carrying angle in this study was observed exclusively as a radiologic angle, although in many studies, it was observed clinically and measured with a goniometer, the results should be interpreted with caution. Although rarely mentioned in previous studies, there are a number of other clinical and radiologic measures that have not been taken into account, and could possibly be useful in evaluating pediatric elbows.…”

Objective: The study aimed to determine relevant radiographic lines and angles of children's elbow Methods: Design: A retrospective cross-sectional study Setting: Tertiary pediatric trauma center Patient Selection Criteria: X-rays of healthy children's elbows aged 0-18 years, in whom the radiographic image of the elbow in two projections was read without signs of fracture and possible indirect signs of fracture, while the exclusion criterion was a clearly visible poor image projection. Outcome Measures and Comparisons: Gender, age [patients were divided into six groups -group 1 (0-3 years), group 2 (4-6 years), group 3 (7-9 years), group 4 (10-12 years), group 5 (13-15 years), group 6 (16-18 years)], side, intersection of the radiocapitellar line in the anteroposterior projection, intersection of the radiocapitellar line in the lateral projection, intersection of the anterior humeral line, Baumann angle, carrying angle, lateral capitellohumeral angle, shaft condylar angle, intersection of the coronoid line and radioulnar overlap. Results: 200 elbows were evaluated. The radiocapitellar line in AP and lateral projections passed through the middle third of the capitellum in 74.5% and 93%, respectively. The anterior humeral line passed through the middle third of the capitellum in 88.5% of cases. When observing the proportion of radiocapitellar lines passing through the middle third of the capitellum in the AP, with increasing age an increasing proportion of lines pass through the middle third of the capitellum [from 8.3% in group 1 (0 to 3 years) to 94.1% in group 6 (16 to 18 years), p = 0.001] and lateral projection (from 50% in group 1 to 100% in group 6, p = 0.023) and anterior humeral line (from 25% in group 1 to 100% in group 6, p = 0.0001). The mean Baumman angle, carrying angle, lateral capitellohumeral angle, shaft condylar angle were 71.59°, 10.97°, 50.84°, and 55.31°, respectively. With age, the shaft condylar angle records the greatest increase (from 41.6° in group 1 to 68.2° in group 6, p = 0.000). A correlation was observed between Baumann's angle and carrying angle (r = - 0.674) and between Baumann's angle and radioulnar overlap (r = 0.542). Conclusions: Considering the anatomical variability of children's elbow, radiological measurements and their interpretation, in the context of timely diagnostics, must be approached with great caution, especially in younger age groups, because it is with them that the largest proportion of lines and angles do not follow established principles.

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. Level of Evidence III, Cross-Sectional Observational Study.
