Radiography of the Hip: Lines, Signs, and Patterns of Disease

Radiography of the Hip:Lines, Signs, and Patterns of DiseaseScot E. Campbell, MDThe complex anatomy of the pelvis and the often subtlebut significant radiographic findings can be challengingto the radiologist. A sound understanding of the standardradiographic techniques, normal anatomy, and Patterns ofdisease affecting the pelvis can be helpful in accurate diagno-sis. This article will review the common radiographic projec-tions in conventional Radiography of the pelvis and hip andwill discuss radiographic anatomy, including the variouslines used to evaluate the pelvis and hip joint. Specific signsand Patterns of Disease will be addressed, with the goal ofproviding a fundamental approach to interpreting hip andpelvis TechniqueCommonly used radiographic projections of the pelvis andproximal femur include the anteroposterior (AP) view of thepelvis, anterior and posterior oblique (Judet) views of thepelvis, AP view of the hip, and frog-leg lateral (Dan Miller)view of the AP radiograph of the pelvis (Fig.)
