Parameters measured for each ligament, using DRC as an example. W: total width of distal radius. A: distance (in mm and as a percentile of W) from dorsal corner of sigmoid notch to ulnar border of ligament origin. B: distance (in mm and as a percentile of the W) from dorsal corner of sigmoid notch to radial border of ligament origin. C: distance (in mm) of ulnar border of ligament origin from articular surface. D: distance (in mm) of radial border of ligament origin from articular surface.
