Hip dysplasia is an abnormality of the hip joint where the acetabular socket portion does not fully cover the ball portion of femoral head, resulting in an increased risk for joint dislocation. DDH ranges from a simple flattening of the acetabular cavity to the complete dislocation of the femoral head. If untreated, DDH can cause early hip osteoarthritis and, in the most severe forms, the presence of a limp with severe functional limitations, since walking age5.In the past, the incidence of severe forms of the disease without an early diagnosis program, was reported to be 0.13% of all newborns. Aim: To assess the usefulness of ultrasonography in early detection of Developmental Dysplasia of Hip joint in infants below 90 days of age. Material and Methods: A Cross sectional study was carried out under department of Radiology at a Tertiary rural health care centre. All neonates born in labor room and infants below 90 days of age receiving outpatient and inpatient care at tertiary rural health care centre fulfilling the inclusion criteria. Thus total 630 neonates were studied. Data were entered in EXCEL sheet and analysed using SSPS software version 20.0. Risk factors were presented and assessed by chi-square. Results: Majority 96.5% neonates had age less than 5 days. Mean age was 3.03+5.5 days, ranging between 1 Day to 86 days. On coronal- neutral HIP angle, on right mean alpha was 61.1 and beta was 61.5 and on left side mean alpha was 60.2 and beta was 62.9. Prevalence of Developmental Dysplasia of Hip joint was found to be 1.6%. Conclusion: Present study showed significance for gender, family history and gestational age. Present study concludes that USG can do early detection of DDH because Clinical presentation of DDH is little late. So for early diagnosis and treatment USG can be used as a screening test for all the newborns for DDH.
