Femoral Triangle

Question 1

Name the borders of the femoral triangle

Answer 1

Inguinal ligament (superior border) 
Lateral border (medial border of sartorius muscle) 
Medial border (medial border of adductor longus muscle - rest of this muscle forms the floor of the triangle)

Question 2

Name the roof and floor of the triangle

Answer 2

Anteriorly - roof - fascia lata

Posteriorly - base - pectineus, iliopsoas, adductor longus muscle

Question 3

Name the contents of the femoral triangle

Answer 3

Femoral nerve 
Femoral artery 
Femoral vein 
Empty space 
Femoral canal - contains deep lymph nodes and vessels

Question 4

What is found in the femoral sheath?

Answer 4

Femoral artery, vein and canal are contained within a fascial compartment

Question 5

Name the contents of the femoral canal

Answer 5

Lymphatic vessels
Deep lymph node
Empty space
Loose connective tissue

Question 6

What is the significance of the empty space in the femoral triangle?

Answer 6

The empty space allows the veins and lymph vessels to distend, so they can cope with different levels of flow.

Question 7

Clinical relevance: femoral pulse

Answer 7

Inferior to where the femoral artery crosses the inguinal ligament, can be palpated to measure the femoral pulse.
Femoral artery crosses midway between pubic symphysis and ASIS (known as mid-inguinal point).

Question 8

Clinical relevance: femoral hernia

Answer 8

Part of bowel pushes into femoral canal, underneath inguinal ligament.
Manifests clinically as a lump or bulge in an area of the femoral triangle. Usually requires surgical intervention to treat.
