Flashcards in Femoral Canal Deck (24):
1

What is the femoral canal?

An anatomical compartment, that is the smallest and most medial part of the femoral sheath

2

Where is the femoral canal located?

In the anterior thigh

3

How long is the femoral canal?

~1.3cm

4

What can the femoral canal be thought of as?

A rectangular shaped compartment

5

What are the borders of the femoral canal?

Medial  Lateral 
Anterior 
Posterior

6

What forms the medial border of the femoral canal?

Lacunar ligament

7

What forms the lateral border of the femoral canal?

Femoral vein

8

What forms the anterior border of the femoral canal?

Inguinal ligament

9

What forms the posterior border of the femoral canal?

Pectineal ligament, superior rami of the pubi, and the pectineus muscle

10

Where is the opening to the femoral canal located?

At its superior border

11

What is the opening of the femoral canal known as?

The femoral ring

12

What is the femoral ring closed by?

A connective tissue layer called the femoral septum

13

What is the femoral septum pierced by?

The lymphatic vessels exiting the canal

14

What does the femoral canal contain?

Lymphatic vessels
Deep lymph node 
Empty space 
Loose connective tissue

15

What do the lymphatic vessels of the femoral canal do?

Drain the deep inguinal lymph nodes

16

What is the deep lymph node of the femoral canal?

The lacunar node

17

What does the empty space in the femoral canal allow for?

Distension of the adjacent femoral vein

18

Why is distension of the adjacent femoral vein important?

So it can cope with increased venous return, or increased intra-abdominal pressure

19

Why is the femoral canal of particular clinical importance?

It is a common site of bowel herniation

20

What happens in a femoral hernia?

A part of the small intestine protrudes through the femoral ring

21

How does a femoral hernia present?

As a lump situated inferolaterally to the pubic tubercle

22

Who is a femoral hernia more common in?

Women, due to their wider bony pelvis

23

What is a hernia with a compromised blood supply known as?

A strangulated hernia

24

Why can a femoral hernia become strangulated?

The borders of the femoral canal are tough, and not particularly extendible, which can compress the hernia, interfering with the blood supply
