Radiographic Determination of Hip Rotation Center and Femoral Offset in Japanese Adults: A Preliminary Investigation toward the Preoperative Implications in Total Hip Arthroplasty

Figure 4

Correlation between teardrop edge-sacroiliac distance (TSD) and vertical distance (VD, length in perpendicular line between HRC and tangential line to inferior edge of teardrop center) in the Japanese males. A linear line of fit is given in the diagram (, , , and VD = 0.179 × TSD + 3.036).
