Talar neck fracture with talar head dislocation and intact ankle and subtalar joints: a case report

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

INTRODUCTION

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.

Talar neck fracture with talar head dislocation and intact ankle and subtalar joints--a rare case report

A rare case of talar neck fracture with intact ankle and subtalar joint is presented. The talar head fragment is dislocated dorsally with the fractured surface of the head facing plantarward. Only two such cases were reported in the literature. The mechanism of injury described in the yesteryears for talar neck fractures does not explain this variety of injury. A possible mechanism of injury has been described. This rare fracture has been successfully treated without any complications after a follow-up of 2 and 1/2 years.
