Acute tarsal tunnel syndrome after pes cavus correction. Can the foot position be a triggering factor?

Abstract

Acute tarsal tunnel syndrome is a rare entity in general population. We present a case report of an acute onset after pes cavus correction, treated with gradual foot plantigrade repositioning with an external fixator, without need of tunnel release. The patient's vivid symptomatology and the good clinical course after conservative treatment, underlines the vulnerability of the tibial nerve when treating patients with stiff varus deformities, and further highlights the importance of gradual corrections by utilising the external fixators in the treatment plan.
