How is a sciatic nerve block performed?

Sciatic nerve block, posterior approach. Needle insertion is in the perpendicular plane; the palpating hand is firmly pressed to decrease the skin–nerve distance and stabilize the anatomy. As the needle is advanced, the first twitches observed are from the gluteal muscles.

How long do sciatic nerve blocks last?

What does sciatic block cover?
