Non-osseous subtalar coalition (PDF and link)  

07.05.2024
A cVRT image of the right foot show an irregular and narrowed subtalar joint involving both middle and posterior subtalar facet, which are deformed. There are no signs of bony bridging, confirming the diagnosis of a non-osseous talocalcaneal coalition. Additionally, a talar beak can be seen at the superior aspect of the talus head. Note that the input images for cVRT creation are reconstructed at 0.2 mm, with a very sharp kernel of Br84u and an image matrix of 1024 × 1024.
