Significant Assessment Discrepancies Occur Between the Examiners Having and Not Having Further Special Hands-on Course Trainings in Infantile Hip Ultrasonography by the Graf Method.

Significant hip US image assessment variabilities exist between the examiners having further trainings by the authorized trainers in special hands-on courses and the examiners having no further trainings in special hands-on courses in the Graf method. The findings of this study may emphasize the importance of training the hip US practitioners in the special hands-on courses for providing a standard clinical practice as well as for avoiding the assessment variabilities between the examiners in the Graf method.
