This case describes delayed treatment of a medial talonavicular dislocation with a shear fracture of the talar head, comminuted posterior talar process fracture, and an intra-articular cuboid fracture with subtle medial displacement of the calcanealcuboid joint and the associated treatment. The injury was sustained in a 35-year-old male following a high-energy motor vehicle accident. Three weeks following the injury, delayed treatment was achieved following an attempted closed reduction under general anesthesia followed by open reduction and percutaneous kirschner wire fixation. After a 12-month follow-up the patient was able to return to work and regular activities pain free without complications. Several associated injuries have been described with isolated talonavicular dislocations. This case reviews the technique and care surrounding this injury pattern and its delayed treatment.
Medial talonavicular dislocation associated with cuboid fracture is rare. We report an 18-year-old man with this injury who exhibited excellent results after open reduction and stabilization of the joint with temporary Kirshner wires.
The talonavicular joint is a rare site of dislocation. Its etiology varies and can be the result of either acute trauma or a chronic degenerative process that most commonly occurs in patients with rheumatoid arthritis or Charcot arthropathy. Our aim is to highlight the relationship between the underlying pathology of talonavicular dislocations and the final outcome in the case of operative management.
We present three cases of talonavicular dislocation with the dislocation itself as the only common denominator, and a completely different etiology, natural history, treatment, and prognosis among them.
There was one case of a traumatic talocalcaneonavicular dislocation in a healthy individual, one case in a rheumatoid arthritis patient, and one case in a patient with diabetes mellitus. All patients were treated surgically. The outcomes were excellent, fair, and poor, respectively.
Among many factors that influence prognosis, it is equally critical to evaluate the overall background in which the dislocation occurs so as to apply the suitable treatment. The surgeon not only needs to treat the local incident but also appreciate the general medical condition to provide the best final outcome to the patient.
