CT to delineate hip pathology in cerebral palsy

Surgical intervention for cerebral palsy hip dislocation or subluxation is frequently undertaken without a full comprehension of the three-dimensional aspects of the femoral-acetabular complex. CT with a modified technique allows more accurate measurement of the angle of femoral anteversion. In this exhibit the authors compare the modified technique with the old technique. Details of femoral had deficits, acetabular configuration, the arc of the acetabulum, the relative position of the femoral head within the acetabulum, and the soft tissue interposed between the femoral head and the acetabulum are well demonstrated with the new technique
