Illustration from 'Surgical Anatomy: The Treatise of the Human Anatomy and Its Applications to the Practice of Medicine and Surgery, volume III' (by Dr. John Blair Deaver) shows how, to reach the nerve, an incision should be made along the middle of the thigh, beginning on a level with the lower border of the gluteus maximus muscle, 1903. For the great sciatic nerve, internal popliteal nerve, peroneal nerve, anterior crural nerve, anterior tibial nerve, external cutaneous nerve, short and external saphenous nerve, internal and long saphenous nerve, and the musculo-cutaneous nerve. The line for the anterior tibial artery, which closely corresponds the to the general course of that vessel, is drawn from a point midway between the tubercle of the tibia and the head of the fibula, to the middle of the intermalleolar space in front. In ligating the anterior tibial artery in its upper third, an incision is made over the course of the artery, beginning on a level with the head of the fibula. In ligating the anterior tibial artery in its middle third, an incision about three inches long should be made over the coure of the vessel. In ligating the anterior tibial artery in its lower third, an incision about two inches long should be made over the line of the vessel, beginning about three inches above the tibio-tarsal artiulation. .
