ABSTRACT

The complete reconstruction of any soft tissue defect includes even the sensory recovery which is very significant aspect pertaining to prognosis. Superficial nerves in the vicinity of the vascular axis can be considered as vascular relays and neuroskin grafts can be constructed on them. Variations in innervation to various part of the dorsum of the foot by this nerve should be kept in mind while making these grafts. Authors dissected 50 formalinized cadaveric feet and studied normal anatomy and variations in origin, course, branching pattern, communications, and any other variations in medial, intermediate and lateral dorsal cutaneous nerve. The intermediate dorsal cutaneous nerve was innervating larger area of the skin around 3rd and 4th web spaces in 60% of cadaveric feet. The 2nd web space was innervated by medial dorsal cutaneous nerve in 92% of cadaveric feet. In 52% of cadaveric feet communicating branches were found between intermediate dorsal cutaneous nerve and lateral dorsal cutaneous nerve. In 63% cadaveric feet communicating branches were found   between medial dorsal cutaneous nerve and branch of deep peroneal nerve to 2nd web space. The mean distance between lateral malleolus and intermediate dorsal cutaneous nerve was 4.05cm. These all observations can provide anatomical basis at the time of preparing medial dorsal cutaneous nerve flaps and intermediate dorsal cutaneous nerve flaps and also can minimize morbidity at donor site.

Key words: Medial Dorsal Cutaneous Nerve, Intermediate Dorsal Cutaneous Nerve, Lateral Dorsal Cutaneous Nerve, Medial Dorsal Cutaneous Nerve  Flap, Intermediate Dorsal Cutaneous Nerve Flap, Soft Tissue Defects, Open Reduction And Internal Fixation Of Fibula, Arthroscopy, Local Anesthetic Block, First Dorsal Metatarsal Artery Flap, Defects In Distal Dorsalis Pedis, Compression And Entrapment Neuropathies.
