Case in brief
A patient with a bimalleolar ankle fracture also had a Jones fracture, a Hawkins type I talar neck fracture, and a calcaneal avulsion fracture. Initial plain radiographs showed the ankle and Jones fractures, but CT was needed to identify the talar neck and calcaneal injuries. The bimalleolar ankle, talar neck, and Jones fractures were treated surgically; the calcaneal avulsion fracture was managed conservatively.
What made this case unusual
The combination of four fractures included two injuries—the talar neck and calcaneal avulsion fractures—that were not visible on initial plain radiographs and were detected on CT.
Diagnostic / clinical pearl
In complex ankle trauma, a visible fracture on plain radiographs does not exclude additional injuries; CT can reveal associated non-displaced talar or calcaneal fractures.
