Anatomic and radiographic evaluation of the hip

The hip is a challenging joint to study is deeply located in the pelvis and surrounding by a large group of muscles with complex tendinous attachments. Our knowledge has recently increased together with the advent of new surgical techniques but further research is needed to better understand hip biomechanics and the relevance of some of radiological findings. Although recent techniques such as MR show anatomy exquisitely is essential to start with pelvis plain radiography for a good evaluation of bone structures and pelvis alignment. During this chapter we will be give a short overview of pelvis normal structures and some key points of MR and MR arthrography technique, because more detailed description is done on every specific chapter.
