Sciatic nerve motor distribution

The motor distribution of the sciatic nerve is as follows

Thigh

• tibial division (posterior compartment of the thigh)
  • long head of biceps femoris
  • semimembranosus
  • semitendinosus
• peroneal division (superficial and lateral to tibial division)
  • short head of biceps femoris

Leg

• tibial nerve (superficial posterior and deep posterior compartments of the leg)
  • gastrocnemius
  • soleus
  • popliteus
  • flexor digitorum longus
  • flexor hallicus longus
  • tibialis posterior
• superficial peroneal nerve (lateral compartment of the leg)
  • peroneus longus
  • peroneus brevis
• deep peroneal nerve (anterior compartment of the leg)
  • extensor digitorum longus
  • extensor hallucis longus
  • tibialis anterior
  • peroneus tertius

Ankle and foot

• medial plantar nerve
  • flexor digitorum brevis
  • adductor hallucis
  • flexor hallucis brevis
  • 1^st lumbrical
• lateral plantar nerve
  • adductor digiti quinti (Baxter’s nerve)
  • quadratus plantae
  • flexor digiti minimi brevis
  • adductor hallucis
  • 2^nd, 3^rd, 4^th lumbricals
  • dorsal and plantar interossei
• deep peroneal (lateral terminal branch)
  • extensor digitorum brevis
