Abstract

Subtalar dislocations represent a spectrum of simultaneous lost of congruence of the talo-calcanealand talo-navicular joints. On the majority of cases, there is an associated bone lesion, with isolatedsubtalar joint dislocation being a rare clinical finding. Commonly, these type of injuries require ahigh amount of kinetic energy, as seen in road traffic accident. Among the four types describedin literature, regarding the foot position to talus, medial dislocation is the most common. Urgentreduction, under sedation or general anesthesia, is mandatory and possibly eased by knee flexionin order to achieve relaxation of the gastrocnemius-soleus complex. Long-term sequelae includeavascular necrosis of the talus, skin necrosis, osteochondral fracture, as well as chronic instability.We present an infrequent case of medial subtalar dislocation resulting from minor sports traumain a young male. This type of lesions, infrequent in the clinical practice of an orthopedic surgeon,constitute a diagnostic challenge in order to achieve reduction as soon as possible, so that potentialcomplications can be reduced.
