First metatarsal-cuneiform dorsal exostosis: its anatomical relation with the medial dorsal cutaneous nerve.

The results of the cadaver dissection show the importance of identifying the proper digital nerve at the time of surgery. In all 20 cadaver dissections, the nerve crossed the first cuneometatarsal joint. Identification of this nerve, along with meticulous dissection may help prevent the formation of postoperative neuroma.
