Fig. 1From: Evaluating the necessity of bone augmentation for distal radius fracture fixed with a volar locking plate: a retrospective studyRadiographic measurements. a Radial height measurement. R is the distance from the distal 1st locking hole to the distal 2nd locking hole in the AP view, which should be fixed in each radiograph, so that that the Radial height/R ratio after correction is shown to minimize statistical error. b Radial inclination measurement is as shown in the figure. c Volar tilt measurement is as shown in the figure. d The status of dorsal collapse. X is the distance from the tip of the dorsal cortex to the 2nd distal locking screw in the lateral view. Y is the distance from the distal 1st to the distal 2nd locking screw in the lateral view. Y is a fixed value in each image, so that the ratio X/Y is shown to minimize statistical errorBack to article page
