Abstract
The popliteal sciatic nerve block is a well-established and popular technique of peripheral nerve blockade in the lower limb. It is a versatile block in that it may be performed in varying patient positions (prone, lateral, or supine), using different approaches (lateral-to-medial, posterior-to-anterior). The landmark-guided technique uses neurostimulation to locate the nerves and is both effective and easy to perform. The advent of ultrasound imaging though has both revolutionized our approach to the popliteal sciatic nerve block and enhanced our understanding of neural anatomy. In particular, the concept of a paraneural sheath in this region is now well-accepted and has changed the way we think about “intraneural” and “extraneural” injections.
