Fig. 6From: A reliable radiographic measurement for evaluation of normal distal tibiofibular syndesmosis: a multi-detector computed tomography study in adultsThe TCS and TFO in the radiographs were measured at the level of plane Y. The “h” was not invariable, which was the perpendicular distance from plane Y (selected in the 3-D image) to the tibial plafond on the anteroposterior view. TCS = tibiofibular clear space; TFO = tibiofibular overlapBack to article page
