Talonavicular Dislocation—What Lies Beneath?

Abstract

Background: 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. Methods: 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. Results: 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. Conclusions: 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.

Medial talonavicular dislocation with nondisplaced navicular fracture: A case report

“…A splint is used until edema subsides and then replaced by a short leg cast or inflatable boot for 3 to 6 weeks. Thereafter, the patient is allowed full weight bearing ambulation [16] .…”

Our results in the treatment of tarsal dislocations

“…Isolated dislocations of the navicular bone without fracture are rare injuries [24]. Because of the complexity of the midtarsal and tarsometatarsal joint complex, the exact mechanism of injury is often not known, particularly when there are multiple deforming forces present, as in high-energy injuries.…”
