FIG. 7-A FIG. 7-B
Fig. 7-A There is mild residual lateral fracture displacement and joint subluxation. Fig. 7-B With the plate used as a reduction tool, both the
fracture and the talus have been reduced to their anatomic position.
FIG. 8-A FIG. 8-B
Fig. 8-A After lateral fixation is complete, the syndesmosis is stressed. Note that the medial clear space and syndesmotic space are widened
while the fibula remains anatomically aligned, indicating syndesmotic instability. Medial clear space widening (arrow) can be appreciated.
Fig. 8-B The syndesmosis is reduced, and a syndesmotic screw is placed. Additionally, with this fixation, the plate is acting as a
substitute lateral cortex.
