Developmental Dysplasia of the Hip (DDH) is a major health problem which can lead to lifelong handicapped condition of individuals if early diagnosis is missed. Cost for treatment, surgery and rehabilitation of these cases is much higher than that for prevention. According to Graf, hip ultrasound screening method is simple, reproducible, innocuous and can be performed by well- trained neonatologists. The purpose of this study is to determine prevalence and types of hip dysplasia by Graf standard screening method. A prospective study was carried out. Hip ultrasound screening using Graf method was performed by neonatologists at the Amgalan of maternity of the Capital city from January 2013 to March 2015.Totally 6154 neonates were eligible for the study and 50.9% of them were male, 93.27% term and 6.72% preterm, in 8.53% of babies, type IIa (physiological retardation of ossification)was found. Dysplasia or dislocation of hips (type III and IV) was found in 5 (0.08%) neonates. Babies diagnosed with type I on both hips were discharged. Type IIa cases were stopped being swaddled and reassessed after 4 weeks. Cases with type III and IV cases were all treated with abduction treatment or Tubinger. This study is an ongoing project. The implementation of the hip ultrasound screening according to Graf is feasible and can be performed by well-trained neonalogists in Amgalan of maternity of the Capital city.
