Tibial nerve divides into medial planter nerve and lateral plantar nerve after passing under the medial malleolus through the tarsal tunnel to enter the foot. From its origin under the laciniate ligament, it passes deep to the abductor hallucis muscle, and, appearing between this muscle and the flexor digitorum brevis. The medial plantar nerve and vessels were located superficial to the first layer of the sole between the plantar aponeurosis and abductor hallucis muscle. (10 foot/ankle and 19 intrinsic) Ten of these muscles originate outside of the foot itself but cross the ankle joint to act on the ankle joint and help position the foot. Variations of nerve are of anatomical, embryological and clinical importance. . These two branches for the tibial nerve are responsible for innervation of the majority of the intrinsic muscles of the foot. Nerve: Tibial Nerve Trigger Point 1 - Refers pain in the instep, spillover pain that extends from the region of the lower posterior thigh over the back of the knee down posterior medial aspect of leg Trigger Point 2 . . 1st by the medial plantar nerve, and 2nd, 3rd, and 4th by the lateral plantar nerve (S2, S3) Extension of toes at the interphalangeal joints: Third Layer • Flexor hallucis brevis: It arises by a Y-shaped tendon: 1.Lateral limb from the medial part of the plantar surface of the cuboid bone. Table 75.2 Medial plantar nerve anatomy Origin L4-S4 ventral rami form the sciatic nerve General route The sciatic nerve divides in the distal thigh into the tibial (Chap. The medial plantar nerve enters the foot between the abductor hallucis and quadratus plantae and then continues distally to give off four digital branches (Fig. or hypothenar eminences are then squeezed together compressing the posterior tuberosity of the lateral plantar nerve and medial calcaneal nerve branches.
