Fracture neck of the talus with isolated talonavicular dislocation: A case report

Talar neck fractures are injuries which frequently result in adverse outcomes or impairment of functional activity. Four groups were identified according to Hawkins classification and Canale modification. We present a female patient with a fractured neck of the talus associated with talonavicular dislocation, but intact tibiotalar and subtalar joints; an injury pattern not fulfilling the criteria described in the Hawkins classification. PATIENT CONCERNS: A 46-year-old woman missed a step and fell down stairs with an immediate painful right ankle and inability to bear weight. DIAGNOSIS: Talar neck fracture with an unusual isolated talonavicular dislocation. INTERVENTIONS: Temporary closed reduction followed by open reduction and internal fixation were performed. OUTCOMES: The patient had excellent functional and radiological outcomes following surgical management. CONCLUSION: We discuss the management of this rare case in addition to a review of the current literature to provide the best evidence-based recommendations for this injury pattern.
