Abstract :Objectives: Developmental dysplasia of the hip insert ignore into journalissuearticles values(DDH); is an important problem. Ultrasonography insert ignore into journalissuearticles values(US); is a proper method before 6 months of age. For older children, plain radiographs can be useful. S ix risk factors are emphasized: breech presentation, female sex, a positive family history, being first-born, left hip affected, and mode of delivery. In some centers, clinicians prefer to perform a control US examination or pelvic radiographs after 6 months of age for the children having a positive family history. We aimed to evaluate the necessity of control US/direct radiography examinations. Methods: A total of 2 05 children with a positive family history for DDH are included. US examinations are performed according to Graf’s method. We have evaluated direct radiographs by using Hilgenreiner, Perkin, and Shenton lines, acetabular angle. Results: Initial US examinations are performed at a median age of 8.3 weeks. Seventy-four patients insert ignore into journalissuearticles values(36%); had a repeat ultrasound scan at a median age of 7 months; none of them demonstrated abnormal findings. One hundred and thirty-one patients insert ignore into journalissuearticles values(63.9%); had control radiographs at a median age of 8.2 months. Shenton line is considered as normal, and the upper femoral epiphysis is located in inferomedial quadrant according to Hilgenreiner and Perkin lines. Conclusions: A positive family history for DDH may be a less important reason for performing control US or radiographic examination. Patients with a normal screening US result and having risk factors can be discharged from follow up safely, so that unnecessary examinations and family anxiety will be reduced.
