A Retrospective Study on the Morphology of Posterior Malleolar Fractures Based on a CT Scan: Whether We Ignore the Importance of Fracture Height

Figure 1

Measurements of the fracture area. The area of the fracture block (S1), which is the purple area, was measured with Extended Brilliance Workspace software. Meanwhile, the area of the residual articular surface (S2), which is the turquoise area, was measured. Then, the fracture area ratio () was calculated.
