TÜRK ÇOCUKLARINDA KEMİK YAŞI TESPİTİNDE "GÖK ATLAS" İLE "GR ATLAS"IN GÜVENİLİRLİĞİNİN KARŞILAŞTIRILMASI

Abstract

ABSTRACT COMPARISON OF THE RELIABILITY OF THE "GÖK ATLAS" AND THE "GILSANZ-RATİB ATLAS" IN THE DETERMINATION OF BONE AGE IN TURKISH CHILDREN Introduction In this study, our aim is to investigate whether the atlases published by GÖK and GR, which are widely used in Turkey, are reliable for use in Turkish children aged 5-10 years, and which results are more correlated with their chronological age. Methods In this study, the wrist radiographs of patients aged 5-10 years who applied to Bakırçay University Çiğli Training and Research Hospital Emergency Department due to trauma wereretrospectively analyzed. Bone age was determined on the wrist radiographs of 180 female and 180 male patients in total, using GR and GÖK atlases. Wrist roentgenograms were compared with the GR Atlas and GÖK Atlas, and the age of the closest picture was taken as the bone age of the film. All assessments on CT images were performed by the radiologist . For intra-observer reliability, measurements were reexamined under blinded conditions by the same radiologist on the randomly chosen 10% (n= 36) of the images after four weeks. Results In general, both GR Atlas and GÖK Atlas made more accurate predictions in males. While the GR Atlas is more compatible with the chronological age in the 5-7-8 -10 age group, the GÖK Atlas is compatible in the 6-9 age group . Conclusion It may be practical to use GR or GÖK Atlases according to the age and gender of the children. 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.
