Figure 1 Measurement of dislocation height on anteroposterior radiographs. A: Inter-teardrop line. H0: Dislocation height, defined as the vertical distance from the junction of the femoral head and neck to the inter-teardrop line. H1: Pelvic width, defined as the vertical distance between the horizontal line of the highest point of the pelvis and the horizontal line of the lowest point of the pelvis. D: Femoral head diameter (28 mm), as a calibration standard.
