Imaging of the pelvis and hip.

Imaging is basic in the orthopedic evaluation of hip disorders. For optimal evaluation of these images, the orthopedic surgeon must not only correlate normal anatomy and pathology with radiographic findings, but must also be familiar with the newer modalities of CT, magnetic resonance imaging and ultrasound and the role and place of these studies in the evaluation of musculoskeletal disorders. This article correlates normal anatomy of the hip with these modalities and discusses the details of these techniques, particularly CT and MRI, that are pertinent to the orthopedic surgeon.
