- Motor distribution of the sciatic nerve
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)
- superficial peroneal nerve (lateral compartment of the leg)
- deep peroneal nerve (anterior compartment of the leg)
Ankle and foot
- medial plantar nerve
-
lateral plantar nerve
- adductor digiti quinti (Baxter’s nerve)
- quadratus plantae
- flexor digiti minimi brevis
- adductor hallucis
- 2nd, 3rd, 4th lumbricals
- dorsal and plantar interossei
- deep peroneal (lateral terminal branch)
