From: A new acute scaphoid fracture assessment method: a reliability study of the ‘long axis’ measurement
Plain radiograph of a scaphoid fracture demonstrating the measurements made. Detailed legend - the long axis (l) and the distance along the long axis to the fracture site are shown (f, fracture distance), while the ulnar (u) and radial (r) distances to the fracture site are also shown. Note (f) is measured along (l) but for ease of demonstrating the methodology (f) has been moved just adjacent to (l). In this example the long axis measurement is f/l which equals 0.28
