Talonavicular Dislocation—What Lies Beneath?

A Short Review and Report of Three Distinctive Cases

View More View Less
Restricted access

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.
