Nerves of the Foot

Images[1]_moved.jpg plantar foot_moved.jpg
  • Branches of the Tibial nerve
    • Medial calcaneal nerve
      • innervates
        • plantar medial heel
    • Medial plantar nerve
      • innervates
        • Abductor Hallucis
        • FHB
        • FDB
        • lumbricals to 2nd and 3rd toes
      • at risk
        • proper branch of medial plantar nerve at risk with medial-plantar approach to the tibial sesamoid
    • Lateral plantar nerve
      • innervates 
        • adductor hallucis
        • quadratus plantae
        • all interossei muscles
        • lateral two lumbricals
        • abductor digiti minimus (via Baxter's nerve - the first branch of LPN)
          • Baxter`s nerve
            • courses anterior to the medial tubersosity between the QP and FDB
      • provides sensation to
        • plantar lateral foot
        • lateral fourth toe
        • fifth toe
    • Physical exam
      • injury to lateral/medial plantar nerve leads to weak or absent MTP flexion (intrinsic minus)
  • Sural Nerve
    • Provides dorsal sensory in 4th web space (70-80% of time)
    • Most vulnerable during
      • extensile lateral approach to calcaneus
      • screw placement for stress fx of proximal 5th MT
      • Achilles tendon repair - especially percutaneous technique
  • Deep peroneal Nerve
    • Innervates EDB, and EHB in foot
    • Provides sensation to the first dorsal webspace
    • Found compressed beneath inferior retinaculum in anterior tarsal tunnel syndrome
    • Lateral branch
      • most vulnerable during removal of calcaneonavicular bar
      • during approach for reduction of Lisfranc injury
    • Injury
      • injury leads to weak or absent EDB and EHB function
        • this can be seen with trauma or CMT
  • Superficial Peroneal Nerve
    • Medial branch
      • dorsomedial aspect of hallux
        • most vulnerable during bunion surgery
    • Lateral cutaneous branch
      • emerges from deep fascia 12-15 cm proximal to tip of lateral malleolus
      • most vulnerable with
        • arthroscopic anterolateral portal
        • ORIF of distal fibula fx (especially Weber C)
    • At risk with ankle inversion injuries
  • Saphenous Nerve
    • Supplies sensation to
      • medial side of foot
