Radiology of the Hip Joint
The aim of this chapter is to describe the different imaging modalities of the hip in the trauma setting; this includes the conventional radiography, which is still an essential modality for fracture evaluation due to fast acquisition, cost effectiveness, and the good overview on hip morphology. However, the acquisition technique has a direct implication on radiographic anatomy of the hip and, therefore, this chapter also aims to demonstrate the different technical principles and views of conventional imaging of the hip. In the trauma setting computed tomography (CT) has emerged as an indispensable tool for detailed preoperative planning with the possibility of 3D-reconstruction and multiplanar reformatting. Magnetic resonance imaging (MRI) of the hip is of minor significance in acute hip trauma but is very helpful to detect occult fractures, assess soft tissue injuries, or evaluate posttraumatic deformities.
