Contents of Femoral Triangle
NAVEL - Femoral nerve, artery, vein, empty space with lymph (fumoral canal with deep lymph nodes)
Femoral sheath
Femoral artery, vein, canal
Nerve NOT included
The proximal opening of the Femoral Canal
Femoral ring
Femoral ring surrounds what Lymph node
Rosenmuller’s Lymph node
Describe how a Femoral Hernia arises
When a loop of small intestine protrudes through the femoral ring into the femoral canal; most common in women
Femoral nerve roots corresponding vertebrae
L2-L4
Meralgia Paresthetic
Compression of the lateral femoral cutaneous nerve as it travels under the inguinal ligament - causes pain and numbness
Cutaneous innervation of the femoral nerve
Lateral femoral cutaneous nerve, anterior femoral cutaneous nerve, saphenous nerve
Saphenous nerve
Supplies skin of anterior/medial knee, leg, foot; becomes superficial between sartorius and gracilis
Adductor Canal
Intermuscular passage that begins at the apex of the femoral triangle and ends at the adductor hiatus (opening of the adductor magnus tendon)
How do femoral vessels reach the popliteal fossa (posterior knee and leg)?
Adductor canal – Adductor hiatus
Chief arterial supply to lower limb?
Femoral artery; inferiorly gives rise to articular branch and saphenous branch
Describe the femoral artery pathway
Begins beneath the inguinal ligament lateral to the femoral vein, travels inferiorly down the femoral triangle (descends on pectineus, iliopsoas, adductor canal), bisects apex deep to sartorius
