1. Describe topographic relationships of the plantar nerves relative to tendons and muscles along  the plantar aspect of the foot. 2. Correlate MR and US with cadaveric images. 3. Discuss compression areas and syndromes related to this anatomy.  

Branches of the posterior tibial nerve: -Medial calcaneal nerve. -Inferior calcaneal nerve. -Medial and lateral plantar nerves. Topographic relationships of the medial plantar nerve (assessed systematically in 6 levels) -Sustentaculum tali. -Between abductor hallucis and quadratus plantae. -Knot of Henry level (‘triangle sign’). -Between flexor brevis tendons, abductor hallucis. -Between flexor tendons and flexor digitorum brevis muscle. -Between flexor tendons. Topographic relationships of the lateral planter nerve (assessed systematically in 5 levels) -Between abductor hallucis and quadratus plantae. -Between flexor brevis and quadratus plantae. -Between flexor brevis and abductor digiti minimi. -Between peroneus longus, flexor brevis and abductor digiti minimi. -Between flexor tendons. Interdigital nerves (assessed in 2 levels) -Superficial to transverse ligament at web space. -Between digits. Specific compression syndromes Jogger’s heel. Jogger’s foot. Abductor hallucis syndrome. Joplin. Baxter’s syndrome. Morton’s neuroma.
