Background: The flexor digitorum longus (FDL) tendon is harvested for use in the reconstruction of dysfunctional adjacent tendons such as the posterior tibial and the Achilles tendons. The approach to harvest the FDL tendon in the midfoot region is through an incision along the medial border of the foot. This approach involves dissection quite deep in the foot across neurovascular structures in the vicinity placing them at risk. The purpose of this cadaver study was to test the feasibility and safety of a minimally invasive technique, and also to define the relevant topographical surface and deeper surgical anatomy. Methods: In 83 cadaver feet, the FDL tendon was harvested proximally in the hindfoot after it was cut through a small plantar incision in the midfoot. All the tissues superficial to the FDL tendon were then reflected to check for damag
