Anatomic and structural evaluation of the hip: a cross-sectional imaging technique combining anatomic and biomechanical evaluations

To describe a technique of cross-sectional imaging of the adult hip designed to evaluate for anatomic anomalies that may predispose to internal derangement in addition to the routine anatomic assessment.Magnetic resonance (MR) imaging, MR arthrography, and multidetector computed tomography (MDCT) scanning protocols utilize high-resolution imaging, and the surrounding anatomy is also assessed using these scanning techniques. Various measurements may be obtained to assess the overarching anatomic configuration including the caput caput collum diaphysis angle, the femoral angle of torsion, the acetabular angle of torsion, the center edge angle, and the femur length.
