Figure <strong>47</strong>-94. Calcaneonavicular coalition in an 11-<br />
year-old with right foot pain. A, Oblique radiograph<br />
shows the abnormal joint in this nonosseous coalition<br />
(arrowheads in magnified dashed box). B, Axial<br />
oblique CT scan through the bottoms <strong>of</strong> the talar<br />
heads (H) shows the symptomatic coalition on the<br />
right foot (black arrowhead) between the elongated<br />
anterior process <strong>of</strong> the calcaneus (APC) <strong>and</strong> the<br />
navicular (N). Incidentally seen is an asymptomatic<br />
coalition on the left (white arrowhead) between the<br />
abnormally broad APC <strong>and</strong> the navicular. C, Axial<br />
oblique CT scan slightly plantar to B. On the right foot<br />
is the symptomatic abnormal joint (arrowhead)<br />
between the broad APC <strong>and</strong> the navicular. On the left<br />
is an extra bone, an os calcaneus secondarius (OCS),<br />
