[Isolated Lateral Subtalar Dislocation Due to Low-Energy Trauma].

Isolated subtalar dislocations constitute 1% of all dislocations and are extremely rare. They frequently occur as a result of high-energy trauma. Dislocations are classified based on the direction of the dislocation, with 80% being medial. Closed reduction under anesthesia without delay is the optimal treatment method. In our case, we present an extremely rare instance of an isolated lateral subtalar dislocation resulting from a low-energy injury. Although isolated subtalar dislocations are frequently reduced with closed reduction, open reduction was necessary in our case. The structure obstructing reduction in lateral dislocations is often reported to be the tibialis posterior tendon. During open reduction, we identified and documented the tibialis posterior tendon as the obstructing structure. We have also discussed the post-reduction follow-up protocol.
