Fig. 1 (a) A set of 67 points were used to delineate the contours of proximal femur, pelvis and acetabulum to create the SSM. (b) and (c) Schematic representation of the predefined geometry parameters used in this study. (b) NW, HR, Wiberg angle (w) “in dark grey”, NSA, TI, dotted line (red line shows resulting radius (R)). (c) Shows in dark grey: SS, PW, IPI “orange triangle”, HAL and offset.

Fig. 2 A visual representation of the extremes of the range of variation of SSM modes 5, 9 and 12 (−2.5 and +2.5 times the population standard deviation). The left and right columns contain true radiographs of subjects with extreme scores on the specific modes.
