Fig. 4From: Volar locking plates not touching the flexor pollicis longus tendon appear as prominences on radiographs: a cadaver studyLines A, B: A line is drawn parallel to the radial shaft over the plate end and radius ulnar border. The distance between points A and B indicates plate-to-radius ulnar border distance (PRU distance). Lines C, D: A line is drawn perpendicular to the radial shaft over the plate end and distal radius. The distance between points C and D indicates plate-to-distal radius distance (PDR distance)Back to article page
