Figure 1.
The maximum of the anterior-posterior or lateral (MAPL) measurement is obtained by measuring the maximum displacement of the most displaced fracture cortex on the anterior–posterior (AP) view as well as the maximum displacement of the most displaced fracture cortex on the lateral view. Then the larger of the two displacement is the MAPL. (a) Lateral and (b) AP are images from one patient; in this case the larger displacement is on the AP view and the MAPL is 23 mm. (c) Lateral and (d) AP are images from a second patient; in this case the larger displacement is also on the AP view and the MAPL is 21 mm. (e) Lateral and (f) AP are images from a third patient; in this case the larger displacement is on the lateral view and the MAPL is 35 mm. (g) Lateral and (h) AP are images from a fourth patient; in this case the larger displacement is on the lateral view and the MAPL is 4 mm.
