The aim of this study is to assess the effectiveness of clinic based ultrasound screening by Orthopaedic surgeon for early diagnosis and treatment of developmental dysplasia of hip (DDH) in one stop clinic. This prospective study included 395 infants (185 male and 210 female) (5.2% of study population) who were referred for screening on the basis of abnormal findings or the presence of risk factors for DDH. Average age was 12.5 weeks (1 day to 15 months). All infants were assessed for risk factors of DDH. Clinical examinations were performed by the senior author followed by ultrasonography of both of the infant's hips, using the Graf's technique. Alpha and beta angles were calculated and hips were classified according to Graf's classification system.Aim
