Risk of Neurovascular Injuries in Flexor Hallucis Longus Tendon Transfers: An Anatomic Cadaver Study

Abstract

Harvesting of the FHL tendon when transection is made distal to the knot of Henry may cause injuries to the medial and lateral plantar nerves. Experience in this procedure may reduce the risk of nerve injuries but even then nerve lesions remain possible. The clinical significance of these nerve lesions is not described in literature and remains to be determined.
