Note the tibial nerve as it follows a distal path through the center of the tibiofemoral joint line, but then quickly courses medially towards the tarsal tunnel. The tibial nerve enters the lower leg then pierces the soleus muscle.

Cutaneous Innervation

  • Medial sural cutaneous n.
  • Medial and lateral calcaneal brs.
  • Lateral dorsal cutaneous n.

Dysfunction

Entrapment sites:

  • Indirect
  • Direct
    • Soleus origin
    • Tarsal tunnel

Palpation

  • Patient positioned in prone
  • Palpate lateral head of the gastrocnemius at the distal joint line of the tibiofemoral joint.
  • Move medially and you should be able to strum the tibial nerve as it runs vertically.
  • Follow the tibial nerve inferiorly to palpate where it passes through the soleus origin.
    • This can be a place where the tibial nerve can be entrapped.

Treatment

Notes

“The tibial nerve, the larger of the two branches of the sciatic nerve, begins its own course in the upper part of the popliteal space. It descends vertically through this space, passing between the heads of the gastrocnemius muscle to the posterior aspect of the leg, and to the posteromedial aspect of the ankle, where its terminal branches serve the foot and ankle (see Chapter 21).”

“The tibial nerve supplies the gastrocnemius, plantaris, soleus, popliteus, tibialis posterior, flexor digitorum longus, and flexor hallucis longus muscles. Articular branches pass to the knee and ankle joints.”
