Evaluation of acetabular coverage: three-dimensional CT imaging and modified pelvic inlet view.
The anterior and posterior coverages of the acetabula were evaluated by comparison of anterior edge-center-posterior edge (ACP) angle by modified inlet view and three-dimensional computed tomographic (3-D CT) images of the hip. Acetabular coverage in 3-D CT images was classified into three grades of front and rear views. The close relationship of this grading and the ACP angle was confirmed. Conventional radiographs with a modified inlet view are usually significant to evaluate the acetabular coverage, however, in the future, 3-D CT images will be routinely used in complicated hip surgery because they provide more detailed information to aid preoperative planning.
