Abstract

The use of peripheral nerves as donor nerves for peripheral nerve regeneration studies, which can provide a long peripheral nerve with intact physiological functions, for autologous nerve grafts was unknown in swine. This study investigated the surgical anatomy of sural nerves (nervus suralis) of cadavers and anesthetized miniature pigs. A loose-S shape incision line was made from the border of the biceps femoris muscle (musculus biceps femoris) to 2 cm above the calx in the leg of anesthetized miniature pigs. The sural nerve was found to branch from the sciatic nerve (nervus ischiadicus) under the biceps femoris muscle and run along the small saphenous vein (vena saphena parva). After being isolated and stimulated using a nerve stimulator, the sural nerve innervated no muscles and tissues in the leg. The sural nerve (14.5
