Lachmans Lower Limb

Question 1

How does the sciatic nerve enter the gluteal region?

Answer 1

Exits the pelvis and enters the gluteal region by passing through the greater sciatic foramen.

In most cases, the sciatic nerve passes inferior to the piriformis muscle.

However, in a common variation, the common fibular portion of the sciatic nerve passes above the piriformis muscle or through the muscle.
