<strong>47</strong> <strong>Ankle</strong> <strong>and</strong> <strong>Foot</strong> 2289 <strong>47</strong><br />
Figure <strong>47</strong>-93, cont’d Although<br />
there are some metallic streak<br />
artifacts, the resolution is high<br />
enough to visualize the widely<br />
spaced cancellous threads <strong>of</strong> the<br />
lag screw in the talus (white arrow)<br />
<strong>and</strong> the narrowly spaced cortical<br />
threads <strong>of</strong> the syndesmotic screw<br />
(white arrowhead). One operation<br />
<strong>and</strong> 16 months later,<br />
anteroposterior (F), mortise (G),<br />
<strong>and</strong> lateral (H) radiographs no<br />
longer demonstrate residual<br />
lucency along the mortise. Mortise<br />
coronal (I) <strong>and</strong> mortise sagittal (J)<br />
CT scans now reveal solid bony<br />
fusion between the tibia (Ti), talus<br />
(Ta), <strong>and</strong> fibula (Fi).<br />
