Nonunion of a Hawkin's group II talar neck fracture without avascular necrosis

The authors present an unusual case of talar neck nonunion without avascular necrosis following a Hawkin's group II fracture. A review of the literature and treatment of this rare complication are discussed. The nonunion was treated by debridement and iliac crest bone grafting to the defect and external electrical bone stimulation. The deformity of the rearfoot caused by the fracture nonunion was addressed by using a triple arthrodesis utilizing the Synthes 7.3-mm cannulated screw system.
