The Atlas-method of Greulich and Pyle (GPA) is widely used for forensic age estimations based on hand-wrist radiographs. The Tanner Whitehouse (TW2RUS, TW3RUS) and Fels methods (FELS) are two other well-known methods. The aim of this study was to investigate bone-age assessment on two samples of hand-wrist radiographs of different ethnic origin. To our knowledge, this is the first comparative study on GPA, TW2RUS, TW3RUS and FELS methods. A total of 174 hand-wrist radiographs from young Danes (12-20 years) and young asylum seekers of mixed ethnic origin (chronological age unknown) were blindly assessed by all methods by two of the authors. Reproducibility was least with the GPA method. TW2RUS had the highest accuracy for boys. FELS had the highest accuracy for girls. Between the three methods bone-age assessments could differ up to three years. Differences among methods were unaffected by ethnic origin. In conclusion, the practical consequences of the choice of method should be kept in mind when performing forensic age estimation. Because relevant information on accuracy of methods can rarely be obtained, the use of more than one method for bone-age assessment should be considered.
