  Fig. 1. (A) The prominence on the posterior inferior aspect of the right medial malleolus (red arrow,) called the “double medial malleolus sign” (yellow arrow, medial malleolus). (B) Lateral radiograph of the right ankle reveals a continuous C-shaped arc (yellow arrows), which is formed by the medial outline of the talar dome and posteroinferior aspect of the sustentaculum tali due to their bridging, and the bony prominence (red arrow) over the right sustentaculum tali and medial process of talus were observed. (C) Axial, (D) semicoronal, and (E) sagittal right ankle computed tomography show talocalcaneal coalition (asterisks) in the posterior subtalar joint. (F) Axial, (G) coronal, and (H) sagittal T2-weighted magnetic resonance imaging of the right ankle reveal the talocalcaneal coalition (asterisks) and tibial nerve adjacent to the coalition. The medial plantar nerve (red arrow) was compressed by the coalition (yellow arrows, lateral plantar nerve). (I) Intraoperative finding of talocalcaneal coalition.
