Unlike congenital dislocation of the hip, developmental dysplasia of the hip is not confined to congenital malformations and includes perturbations in development 12. there is a clear female predominance, and it usually occurs from ligamentous laxity and abnormal position in utero. therefore, it is more common with oligohydramniotic pregnancies. Developmental dysplasia of the hip (ddh) encompasses a wide spectrum of clinical severity, from mild developmental abnormalities to frank dislocation. clinical hip instability occurs in 1% to 2% of full term infants, and up to 15% have hip instability or hip immaturity detectable by imaging studies. hip dysplasia is the most common cause of hip arthritis in women younger than 40 years and.

Objective. the purpose of this article is to review developmental dysplasia of the hip (ddh), a well described entity previously evaluated with a standard multimodality imaging algorithm, typically consisting of ultrasound and radiography depending on patient age. conclusion. mri is increasingly used because it is a noninvasive imaging modality that offers excellent anatomic detail, enabling. Pediatrics (2019) 143 (1): e20181147. pediatricians are often the first to identify developmental dysplasia of the hip (ddh) and direct subsequent appropriate treatment. the general treatment principle of ddh is to obtain and maintain a concentric reduction of the femoral head in the acetabulum. achieving this goal can range from less invasive. A recent study compared the use of ct ver sus mri to evaluate hip reduction in patients with ddh and found that both modalities of fer excellent sensitivity and specificity [27]. ct had sensitivity of 100% and specificity of 96% for the postoperative nonsubluxed hip, whereas mri showed sensitivity of 100% and a specificity of 100%. The left hip is still dysplastic with there still being a shallow acetabulum and decreased alpha angle even though the left hip appears fairly well located in the left acetabulum. the left hip alpha angle measured 45 degrees (normal is usually greater than 60 degrees) but had increased since the last exam.

Developmental dysplasia of the hip (ddh) is a multifactorial derangement of the femoral head and acetabular relationship starting in utero . femoro acetabular relationship works in a synergistic manner, that is, a well placed femoral head within the acetabulum helps the acetabulum to develop optimally and vice versa. Epidemiology, disease burden, and clinical presentation. developmental dysplasia of the hip is a common condition seen in children worldwide, with incidence ranging from 1–34 1000 live births. left untreated, it is also one of the most common factors leading to premature arthritis of the hip. ddh encompasses a spectrum of anomalies ranging.
