Figure 18a. Acute calcaneal fracture with tendon entrapment in a 25-year-old man. (a) Sagittal MPR image shows fracture of the calcaneus with depression of the Boehler angle. (b) Coronal MPR image shows lateral and superior displacement of the calcaneal fragment, which results in entrapment of the peroneal tendons (arrow). (c) Posterolateral VR image shows entrapment of the peroneal tendons between the fibula and calcaneus (arrow). (d) Posterolateral VR image of the bones shows the proximity of the fibula to the calcaneus.
