Procedure: Exposure of the Sciatic Nerve

The sciatic nerve is the largest nerve in the human body. It originates from the L4–S3 nerve roots, exits the pelvis through the sciatic notch covered by the piriformis and gluteus maximus muscles, and courses between the hamstring muscles of the posterior thigh.

A 59-year-old man presents to the emergency department with acute onset of impaired speech and right-sided weakness. He has a history of hypertension and hyperlipidemia.
