Sciatic nerve block
Sciatic Nerve Block
The Sciatic Nerve Block (pronunciation: /saɪˈætɪk/ /nɝːv/ /blɑːk/) is a medical procedure used to alleviate pain or provide anesthesia to the lower extremities.
Etymology
The term "Sciatic" is derived from the Latin word "sciaticus", which refers to the hip or the region of the hip-joint. The term "Nerve Block" is a combination of the words "nerve", which refers to the fibrous cords that transmit impulses to the muscles and organs, and "block", which refers to the act of making the passage of these impulses difficult or impossible.
Procedure
The Sciatic Nerve Block is performed by injecting a local anesthetic near the sciatic nerve, which is located in the lower back and runs down each leg. This procedure can be performed under ultrasound guidance to ensure accurate placement of the anesthetic.
Uses
The Sciatic Nerve Block is commonly used in surgeries involving the lower leg, foot, and ankle. It can also be used to manage chronic pain conditions that affect these areas.
