Case Discussion

In this case, the MRI reveals a fibrous connection between the talus and calcaneus, accompanied by surrounding reactive edema that is consistent with talocalcaneal coalition. The patient underwent surgical excision of the middle facet coalition without any complications. During the three-week post-operative checkup, the patient exhibited remarkable progress in physical therapy with only occasional use of acetaminophen, while radiography revealed appropriate post-surgical changes.
