Flashcards in MSK - The Femoral Canal Deck (16):
1

Where is the femoral canal located?

In the anterior thigh, in the femoral canal

It is the smallest and most medial pat of the femoral sheath

2

What shape compartment is it?

Rectangular

3

What is the medial border of the femoral canal?

Lacunar Ligament

4

What is the Lateral border of the femoral canal?

Femoral Vein

5

What is the Anterior border of the femoral canal?

Inguinal ligament

6

What is the Posterior border of the femoral canal?

Pecineal ligament and Superior Rami of the Pubis

7

Where is the opening to the femoral canal?

What is it known as?

What is it closed by?

Superior Border

The Femoral Ring

Closed by a connective tissue layer known as the femoral septum

What does the femoral canal contain?

Lympthatic Vessels

Deep Lymph Nodes - The Lacunar Node

Empty Space

Loose Connective Tissue

10

What is the empty space of the femoral canal to allow for?

Allows distension of the adjacent femoral vein so it can cope with:

a) Increased Venous Return

b) Increased Intra-Abdominal Pressure

11

The femoral canal is a site of clinical importance because it is a common site of what?

Bowel Herniation

12

What is the definition of a hernia?

‘where an internal part of the body pushes through a weakness in the muscle or surrounding tissue wall‘

13

What happens during a femoral hernia?

Part of the small intestines protrudes through the femora ring

14

How does a femoral hernia present?

As a lump situated inferiolaterally to the pubic tubercle

15

Why is this type of herniation seen more commonly in women?

Due to their wider bony pelvis

16

How could a strangulated hernia occur?

The borders of the femoral canal are tough, and not particularly extendible. This can compress the hernia, interfering with its blood supply. A hernia with a compromised blood supply is known as a strangulated hernia
