Sartorius Fascia

fascia sartorii

The sartorius muscle fascia forms the medial boundary of the femoral triangle and the roof of the proximal adductor canal as the muscle spirals from the ASIS to the medial tibia.

Region: Thigh

Biomechanics

Function & Actions

Provides the medial femoral triangle boundary where femoral vessels and nerve are identified and defines the proximal adductor canal roof.

Clinical Relevance

Clinical Notes

Femoral nerve lies lateral to the femoral artery beneath the fascia iliopectinea at the sartorius medial border — the reference for ultrasound-guided femoral nerve block.

Femoral Nerve Block Using Sartorius Fascia Reference

The sartorius medial border guides femoral nerve block — the nerve lies lateral to the femoral artery beneath the fascia iliopectinea.
