Türk Çocuklarında Kemik Yaşı Tespitinde “GÖK Atlas” ile “Gilsanz-Ratib Atlas“ın Güvenilirliğinin Karşılaştırılması

Abstract

Aim: In this study we aimed to evaluate which of the GÖK and GR atlases is more compatible with chronological age in Turkish children aged 5-10 years.
 Material and Method: In this study, the wrist radiographs of patients aged 5-10 years who applied to İzmir Bakırçay University Çiğli Training and Research Hospital due to trauma were retrospectively analyzed. A total of 360 wrist radiographs were evaluated. Bone age estimates in both groups were compared with chronological ages. 
 Results: In the correlation analysis, the prediction rate with 1-difference tolerance is 88.9% in the GR atlas and 76.7% in the GÖK atlas, while both atlases predict 99% correctly with two-difference tolerance. GR Atlas 168 (46.2%) and GÖK Atlas 147 (40.8%) predicted correctly regardless of gender and age. Of the correct estimations, 53.5% in the GR atlas and 57.8% in the GÖK atlas were male cases. İn male age group at the age of 6 and 10, the GR atlas is more successful, at the age of 7, the GÖK Atlas is more successful, and at the age of 5, 8, and 9 the success of both atlases is the same. İn female age group at the age of 5,7, 8, and 10 the GR atlas is more successful, at the age of 6 and 9 the GÖK Atlas is more successful
 Conclusion: The GR Atlas was more accurate than the GÖK Atlas. Both the GR Atlas and the GÖK Atlas predicted more accurately in males. Since reference values for bone age can change with environmental and genetic factors all over the world, it is beneficial for all races to create atlas models with multicenter studies in order to establish their own standards.
