Abstract
Introduction
This study aims to study the degree of interobserver agreement in the interpretation of radiological tests used for forensic age estimation in migrant minors without family references between the radiologist and the forensic doctor and between the two forensic doctors who evaluated each case.
Materials and methods
This is a prospective study of the 69 cases studied at the Institute of Legal Medicine and Forensic Sciences of Alicante during 2023 and 2024. Each observer assessed and assigned a stage, following the Greulich and Pyle atlas for hand and wrist radiographs, the Demirjian stages for panoramic radiographs, and the Schmeling and Kellinghaus classifications for computed tomography scans of the proximal clavicle.
The IBM SPSS Statistics 28.0 statistical package was used; obtaining both the percentage of observed agreement and the Kappa index, which corrects for chance.
Results
The degree of agreement between the two forensic physicians was very good for the hand and wrist radiograph (k = 0.931), very good for the panoramic radiograph (k = 0.828), and substantial for the computed tomography (k = 0.671). However, the degree of agreement between the radiologist and the forensic physician was lower for all three tests: substantial for the hand and wrist radiograph (k = 0.748), moderate for the panoramic radiograph (k = 0.434), and modest for the computed tomography (k = 0.285).
Conclusions
These results highlight the importance of training and instruction in the forensic medical evaluation of these radiological tests.
