Emergency definitive management of a subtalar dislocation with an associated lateral malleolus fracture

Lateral subtalar dislocations are rare injuries with the potential for misdiagnosis and for poor patient outcomes if missed. Prompt reduction and surgical intervention is the consensus and is key to improved patient outcomes.We present a case of a male patient in his 70s who was brought in by ambulance to the emergency department late one afternoon with a lateral subtalar dislocation associated with calcaneal and lateral malleolar fractures. He was operated on that evening, involving cannulated screw fixation of the calcaneus and buttress plating of the lateral malleolus. Non-weight-bearing mobilisation was permitted at 2 weeks and weight-bearing was commenced at 6 weeks postoperatively.The authors could not find any precedent in the literature for same-day definitive fixation and early mobilisation of this rare but significant injury, the combination of which resulted in excellent functional outcomes for the patient.
