Naviculocuneiform arthrodesis.

NC arthrodesis is a useful procedure to alleviate pain secondary to arthritis or collapse of the medial longitudinal arch. Fusion of this joint provides stabilization of the medial column and is often used in conjunction with other flatfoot-correcting procedures to restore normal function to the foot. Because the NC joint is the center of the lever arm of the foot and is therefore subject to bending-moment stress, concomitant gastrocnemius recession or tendo-Achillis lengthening is recommended.
