| Lateral Plantar Nerve | |
|---|---|
| Nerve Type | |
| Origin | L4-S4 ventral rami from the sciatic nerve where it runs through the deep posterior compartment of the leg and divides into the lateral plantar nerve within the tarsal tunnel. |
| Course | Travels under the abductor hallucis and diagonally across the sole between the flexor digitorum brevis and quadratus plantae |
| Major Branches | Inferior Calcaneal Nerve (Baxter Nerve), Terminal branches at the mid-lateral edge of the flexor digitorum brevis. |
| Sensory innervation | Fat pad over the fifth metatarsal head, skin of lateral sole. The baxter nerve branch supplies the periosteum at the medial calcaneal tubercle and long plantar ligament. |
| Motor innervation | Flexor Digiti Minimi Brevis (Foot), Flexor Accessorius, Adductor Hallucis, the third and fourth interosseous muscles |
| Conditions | Lateral Plantar Nerve Entrapment |
