Aim: The aim of the study was to assess the usefulness of obtaining a 900 angle between the plane of the osteochondral plate and the surface of the transducer during standard hip ultrasonography according to Graf method.
Material And Methods: In this retrospective study 1078 patients (2156 hips) were included examined between 2008 and 2014 for developmental dysplasia of the hip (DDH) ultrasound screening. The patients were divided in two groups. Group I consisted of 402 patients examined between January 2008 and December 2011 using the standard Graf method. Group II consisted of 676 patients examined from January 2012 to December 2014 using the Graf method with an additional criterion: 900 angle between the plane of the osteochondral plate and the surface of the transducer.
Results: We found more dysplastic patients in group I comparing to group II: 55 (13.7%) and 38 (5.6%) respectively. The difference in the incidence of patients diagnosed with DDH was highly significant (p<0.001). The mean alpha angle value in group I was 65.310, respectively 67.520 for group II (p<0.001).
Conclusion: The new osteochondral plate sign has the potential to reduce the overdiagnosis of DDH and provide a better tailored approach to borderline hips.

Graf ultrasound screening is considered an established method for early detection of developmental dysplasia of the hip (DDH). Although characterized by a high degree of standardization to allow for good reproducibility of results, examination-related factors may still affect sonographic measurements. The relative tilt angle between the hip and the probe is a potential pitfall as it significantly influences sonographic measurements and consequently classification of DDH according to Graf.

Background: The orthopedic department at Al Jalila Children's Specialty Hospital (AJCH) was opened in April 2018. A focused hip ultrasound training course was conducted in April 2019 to improve hip ultrasound imaging quality.
Objectives: This study aims to evaluate the impact of focused training courses on predefined image quality criteria of infant hip ultrasound in the context of developmental hip dysplasia.
