Neglected medial swivel talonavicular dislocation treated with arthrodesis: A case report and literature review

Talonavicular dislocation is a rare injury. It usually occurs in conjunction with a variety of midfoot and hindfoot injuries. Isolated medial or lateral talonavicular dislocations without disruption of subtalar joint are known as medial or lateral swivel dislocations respectively, both being extremely rare. We describe a case of neglected medial swivel dislocation with articular impaction injury of talar head, which was managed with open reduction and arthrodesis with two 4 mm cannulated cancellous screws. At 6 months follow-up, patient was pain free and walking full weight bearing. All movements were painless and there was no footwear related problems. Radiographs showed sound arthrodesis of talonavicular joint. Although a rare injury, good results can be obtained by prompt recognition and treatment. In neglected cases, arthrodesis of the talonavicular joint is a viable option, especially if articular injury is present.
