title: Inferomedial (subsustentacular) dislocation of the navicular: a case report.
abstract: A unique case of subsustentacular dislocation of the navicular is presented. The authors propose that such a severe displacement cannot occur until there is complete instability across the whole midfoot. The mechanism of injury and the treatment options are discussed. In the present case, there was late collapse of the foot into abduction because the lateral column was not primarily stabilized. Avascular necrosis is a common complication which leads to navicular collapse. A midfoot arthrodesis gave a good result in our patient.
