Role of Ultrasound in assessment of Developmental Dysplasia of the Hip Joints

Abstract

Background:Developmental dysplasia of the hip (DDH) include spectrum of anatomical abnormalities of the hip joint (dislocated, subluxed ,and dysplasia) arising from a deviation in normal hip development during embryonic, fetal and infantile growth periods.the use of ultrasonography is recommended as well as the clinical evaluation. It is the best to clarify the physical finding, detect a high-risk infant and monitoring DDH to be observed or treated Objectives:Ultrasound has provided increased accuracy in comparison to the clinical and radiographic examinations which has been the accepted techniques for evaluating the hip in the first year of life Patients and methods: The current study was aretrospective study conducted at qena university hospitalfrom 2019 to 2020.ultrasound machine used to obtain alpha angle , assessment of structural anatomy and hip joint stability. Results: right leg affection is represented in 25% for clinically suspected analyzed cases. Left leg represent 30% , both legs represent 40% . Conclusion: Ultrasonographic techniques include static assessment of morphologic features of the hip, as popularized in Europe by Graf and a dynamic evaluation, as developed by Harcke that assesses the hip for stability of the femoral head in the socket, as well as static anatomy. the use of ultrasonography is recommended as an adjunct to the clinical evaluation. It is the technique of choice for extract a physical finding,detect a high-risk infant and monitoring DDH to be observed or treated.
