Abstract
Developmental dysplasia of the hip (DDH) is still one of the biggest orthopedic problems in the world. Global poverty and refugee crises have led to it becoming a greater issue even in developed nations. Early diagnosis and effective treatment of DDH are required to prevent the possibility of arthrosis, limb shortening, pelvic asymmetry, and vertebral scoliosis. In late cases, surgery is the only choice for correction. Direct radiography has been used for many years and continues to have an important role, though ultrasonography is the primary source for early postnatal screening. Although magnetic resonance imaging (MRI) has become an important modality to provide sectional imaging in many cases, in late-period dysplasia, computed tomography (CT) and three-dimensional (3D) CT are preferred because it can more effectively demonstrate the cortical bony structures. The aim of this review was to demonstrate the effectiveness of 3D CT and multiplanar reconstruction based on previous studies.
