Figure 3. Measurement and calculation of the displacement. The percentage of the non-overlapping fracture line length in the total fracture line length was used to calculate the fracture displacement. (a) Example of the coronal displacement: 6.2/(6.2+7.5)x100= 45. (b) Example of the sagittal displacement: this fracture was considered to be 100% displaced in sagittal plane, because it has a bayonet apposition and there is no overlapping of the fracture line in the sagittal plane.
