Abstract
The cutaneous innervation of the medial dorsal aspect of the first toe has been reported to originate from different nerve branches. Twenty cadaver feet were dissected to determine the origin of this nerve. In all 20 feet the medial dorsal cutaneous nerve arose from the medial dorsal cutaneous branch of the superficial peroneal nerve. This cutaneous innervation of the first toe is encountered during bunionectomy, first metatarsal osteotomy, excision of the metatarsal head and/or proximal part of the proximal phalanx, arthroplasty, and arthrodesis of the first MTP joint. The information concerning the course and origin of this nerve should assist protection during operative procedures, as well as enable quick localization and identification.
