Calcaneonavicular Coalition with Naviculocuneiform and Cuneiform-First Metatarsal Coalitions A Case Report.

Coalitions involving three joints of the midfoot are rare. To our knowledge, this is the first report of a patient having fibrocartilaginous coalition of the calcaneonavicular joint along with partial osseous fusion of the naviculocuneiform (Chopart's joint) and medial cuneiform-first metatarsal joints. These multi-coalition pathologies are challenging to address operatively as pain can persist even after recognizing and surgically addressing each coalition in a patient.
