Evidence of a medial, lateral, or posterior malleolar fracture or other defects was not clear (Figure 1).
The initial transverse view (A-D), coronal view (E,F), and sagittal view (G,H) CT images of the ankle, and 3D reconstruction image of the foot and ankle (I-L).

Computed tomography (CT) images of the ankle showed an avulsion fracture of the anterior tibia by the anterior inferior tibiofibular ligament (AITFL) with a nondisplaced bony fragment (Figure 2).
The initial transverse view (A-C) and coronal view (D-F) MRI images of the ankle.

However, magnetic resonance images suggested no injury of the posterior inferior tibiofibular ligament, interosseous tibiofibular ligament, deltoid ligament, and both the medial and lateral malleoli (Figure 3).
Frontal (A, C, E, G, I) and lateral (B, D, F, H, J) view CT images of the proximal tibia (5 days, 2 weeks, 6 weeks, 3 months, and 6 months after the injury).

Plain radiographs showed successful recovery of the fracture at the proximal fibula (Figure 4).
