Plantar foot anatomy scheme: arteries and nerves

The path of plantar arteries (red) and nerves (green) to the toes is shown. Each digit is innervated by four digital nerves; the dorsal arteries and nerves are not shown in this figure. In order to achieve a complete anesthetic effect, it is necessary to block all four nerves. For a complete block of the great toe, there are additional branches that come up the dorsal aspect of the great toe that can be missed if anesthetic is only injected laterally and medially. In general, foot injections are not performed in the plantar surface.
