2288 VII Imaging <strong>of</strong> the Musculoskeletal System<br />
A B C<br />
Figure <strong>47</strong>-93. Attempted<br />
arthrodesis. The patient is a 68-<br />
year-old farmer who injured his<br />
ankle 6 years earlier when he misstepped<br />
getting <strong>of</strong>f his tractor. He<br />
underwent arthrodesis surgery 3<br />
years ago, <strong>and</strong> this was revised 1<br />
year ago because <strong>of</strong> failure <strong>of</strong><br />
fusion. The patient is experiencing<br />
persistent pain. Anteroposterior<br />
(A), mortise (B), <strong>and</strong> lateral (C)<br />
radiographs reveal a plate <strong>and</strong><br />
several screws across the ankle<br />
mortise <strong>and</strong> syndesmosis.<br />
Although the metal obscures<br />
visualization <strong>of</strong> portions <strong>of</strong> the<br />
mortise, no bony fusion is seen<br />
medially (black arrowheads).<br />
D <strong>and</strong> E, CT scans were requested<br />
to see if any fusion was present.<br />
Mortise coronal (D) <strong>and</strong> mortise<br />
sagittal (E) images clearly show no<br />
bony bridging throughout the<br />
ankle mortise (black arrowheads).<br />
