Flashcards in Anteromedial thigh Deck (46):
1

The fascia Lata

Is a thickening of the deep fascia covering the thigh and separating the muscle compartments.

2

Attachment points of the fascia lata are

Superiorly: Pubic tubercle, pubis and inguinal ligament
laterally: Iliac crest
Posteriorly: sacrum, coccyx and ischial tuberosity

3

What consists of the illiotibial band?

The blending of the fascia lata with the tendon of the 'tensor fascia lata muscle'

4

Where does the illiotibial band attach to?

The lateral aspect of the tibia

5

What is the one deficiency of the fascia lata, and what passes through this?

The Saphenous opening, for which the great saphenous vein passes through to meet the femoral vein.

6

Which of the intermuscular septa (that form thigh compatrments with the fascia lata) is the strongest and therefore easiest to find?

The lateral intermuscular septum

7

Why is the Tensor Fascia Lata muscle considered a gluteal muscle

Because its embryonic origin is in the gluteal region

8

What are the 8 Anterior compartment muscles of the thigh?

Vastus Lateralis
Vastus intermedius
Vastus Medialis
Rectus Femoris
Sartorius
pectineus* (partially)
Psoas Major
iliacus

9

What consists of the iliopsoas and what is the common attachment point of this?

Iliacus and psoas major. These muscles both insert as the lesser trochanter of the femur

10

Where do the Iliopsoas muscles originate from?

Iliacus= iliac fossa and lateral sacrum
Psoas Major= lumbar vertebrae

11

Where does the tensor of the fascia lata originate?


ASIS and iliac crest

12

Where does the Sartorius muscle insert and originate from?

Origin= ASIS
Insertion= superior medial tibia (pes anserinus)

13

what is the function of the iliopsoas muscle?

To FLEX and EXTERNALLY ROTATE the thigh

14

What constitutes the Quadriceps Femoris?

Rectus Femoris
Vastus lateralis, medialis and intermedius

15

what is the common insertion of the quadriceps femoris?

Superior Patella

16

What is the common action of the quadriceps femoris, and what is the exception?

Extends leg via knee
Rectus Femoris also flexes the thigh at the hip joint

17

Where does the vastus lateralis originate?

The greater trochanter and linea aspera

18

Where does the vastus medialis originate?

Intertrochanteric line, medial intermuscularsepta

19

Where does the vastus intermedialis originate?

sup 2/3 femoral shaft
lateral intermuscular septa

20

Why is the pectinius muscle considered both an anterior and medial muscle?

Because it is innervated by both the femoral and obturator nerve. It flexes the thigh as well as adducting it.

21

What constitutes the femoral triangle

The femoral nerve, vein and artery as well as lymphatics

22

The borders of the femoral triangle are made up of

Lateral: Sartorius
Medial: Adductor longus
superiorly: Inguinal ligament
Floor: iliopsoas, adductor longus and pectinius
Roof: subcutaneous tissue, skin and fascia lata

23

The femoral SHEATH contains

The femoral vein, artery and lymphatics. NOT the femoral nerve

24

The femoral canal is.... and how is this important clinically?

A compartment of the femoral sheath that contains lymphatics. What can occur is the abdominal contents can herniate into the femoral canal "femoral Hernia"

25

What is the order of the femoral triangle lateral > medial

Nerve, artery, vein, lymphatics

26

How would you perform a femoral nerve block?

Find the femoral artery (via pulse). inject just LATERALLY to the artery. This is better then using lots of medication.

27

What are the five medial thigh muscles and what is their nerve innervation

Adductor Longus
Adductor Brevis
Adductor Magnus* (both med and post)
Gracilis
Obturator externus
*pectinius

Nerve: obturator (L2-L4)

28

What is another name for Adductor canal and why?

Subsartorial Canal as it occurs deep to the middle third of sartorius

29

What are the boundaries of the adductor canal?

Medial: Sartorius
Lateral: Vastus medialus
Posterior: Adductor Longus and magnus
Inlet: Apex of femoral triangle
outlet: adductor hiatus (adductor magnus muscle

30

What are the actions of the sartorius muscle

Flexes, abducts, externally rotates thigh, flexes leg

31

What is the origin of Rectus Femoris straight head?

AIIS

32

What is the origin of Rectus Femoris reflected head?

superior acetabular rim

33

what is the general order for BOTH the aterial and venous femoral vessels?

Aorta-common iliac artery-external iliac artery- femoral artery

Inferior vena cava-common iliac vein-external iliac vein- femoral vein

34

What is the structural boundary that defines the femoral vessels?

Inguinal ligament

35

Where do both Gracilis and adductor longus originate from?

Body of pubis

36

Where do both adductor longus, brevis and magnus insert to? And where are the extra insertion points for the broad adductor magnus muscle?

Linea Aspera.
Extra points are medial supra condylar ridge and adductor tubercle.

37

The adductor magnus originates from two point on the pelvis, what are these and which part belongs to which group?

Adductor: Inferior pubic ramis
Hamstrings: Ischial tuberosity

38

What are the common movements of the Adductor muscles and gracilis?

Adducts and flexes thigh

39

What makes adductor magnus special in regards to movement?

Due to it's broadness/curvature, it can both flex and extend the thigh using different fibres

40

Where does gracilis insert and what does that mean about it's movement

Insertion: superior medial tibia.
Therefore it can adduct/flex thigh AND internally rotate leg

41

Where is the femoral nerve formed and how?

From L2-4 and is formed within psoas major

42

What does the femoral nerve supply and where does it go?

Supplies flexors of the hip and extensors of the knee in the ant compartment. The terminal branch descends medially and becomes the saphenous nerve (cutaneous).

43

What are the cutaneous branches of the femoral nerve and what do they supply?

Anterior Cutaneous nerve of thigh: anterior thigh
Saphenous Nerve: Medial aspect of leg

44

What is the purpose of the tensor of the fascia lata?

Abducts and stabilizes thigh

45

What are the contents of the adductor canal?

femoral artery and vein, saphenous nerve and nerve to vastus medialis

46

O/I of Pectineus

O: superior pubic ramus
I: inferior to lesser trochanter
