Fig. 4From: Accuracy and practicability of a patient-specific guide using acetabular superolateral rim during THA in Crowe II/III DDH patients: a retrospective studyWe used computed tomography to present the transverse view to measure the anteversion (a) and the coronal view (b) to measure the inclination. We used a standard pelvis anterior-posterior X-ray (c) to assess the BRCD (BRCD = |b-a|). a and b represent the distance between the rotator center and the line that passes through the bilateral teardropBack to article page
