Abstract

This paper reports a rare case of the symptomatic third metatarsal (MT3) - lateral cuneiform (LC) in a 55-year-old male who presented with complaints of severe intermittent pain in his right foot. Plain radiographs and computed tomography scans revealed sclerosis and irregularity at this joint. The intraoperative findings demonstrated a fibrocartilaginous coalition. The pain had improved one year after removing the MT3-LC joint by en bloc and arthrodesis.
