Anterior tarsal tunnel syndrome secondary to missed talus fracture: a case report

Abstract

The anterior tarsal tunnel syndrome (ATTS) has first been described by Kopell and Thompson in 1963. The anterior tarsal tunnel is formed by the fascia lining the inferior extensor retinaculum and talus as well as the navicular bone. Many ATTS cases with various etiologies have been reported since the first description. We report here an ATSS case resulting from a fibro-osseous structure that occurred after a missed talus fracture. The ATTS diagnosis can be made with a comprehensive clinical neurological examination and electrophysiological study. The treatment is based on the underlying etiology, while surgery is the most common treatment providing successful outcomes in the long term.
