2. Introduction
• Anterior or fascial compartment extends between hip & knee joints.
• Three intermuscular septa divide the thigh into three compartments.
I. Lateral intermuscular septa which separates ant. Compartment of thigh from
medial compartment.
II. Medial intermuscular septa which separates ant. Compartment from
posterior compartment.
III. Posterior intermuscular septa separates the medial compartment from
posterior compartment.

4. FASCIAE OF ANT. THIGH
Superficial fascia
• It has two layers,
a. Superficial fatty layer.
b. Deep membranous layer, which continuous with layer of ant. Abdominal wall.
c. Membranous layer loosely attaches to deep fascia of thigh except near inguinal
ligament, where it firmly attached to horizontal line called Holden’s line.

6. FASCIA OF ANT. THIGH
Deep fascia or fascia lata.
The fascia lata is though fibrous sheath covering the
whole thigh like a sleeve. It attached
• superiorly, to boundary line between lower limb
and pelvis
• Anteriorly, inguinal ligament
• Laterally, iliac crest
• Medially, to pubis, pubis arch & ischial tuberosity
• Inferiorly, sides of knee, capsule of knee joint.
(fascia lata continuous as the fascia of leg)
6

7. ILLIOTIBIAL BAND (IT BAND)
• It is a laterally thickening of fascia lata.
• Superiorly, tract splits into two layers,
superficial and deep laminae.
(Superficial lamina attaches to tubercle of
iliac crest & deep lamina to capsule of hip
joint).
• Inferiorly, attaches to lateral condyle of
tibia.
• It gives attachment to tensor fascia lata &
gluteus maximus.

8. SAPHENOUS OPENING
• It is an oval shape opening in fascia
lata is 4cm below & 4cm lateral to
pubic tubercle.
• Fascia covering the opening is called
cribriform fascia.

9. FEMORAL TRIANGLE
9
• It is a triangular depression on the front of upper
one-third of thigh.
BOUNDRIES
• Laterally, medial border of sartorius.
• Medially, medial border of adductor longus.
• Base formed by inguinal ligament.
• Apex is formed at meeting point of adductor
longus & Sartorius.
• Roof formed by superficial fascia & deep fascia.
• Floor formed medially by adductor longus &
pectineus, laterally by psoas major & illiacus.

10. CONTENTS OF FEMORAL TRIANGLE
• Femoral artery and its branches.
• Femoral vein & tributaries.
• Femoral sheath covering the upper
4cm of femoral vessels.
• Femoral nerve, femoral branch of
genitofemoral nerve & lateral
cutaneous nerve of thigh.

11. FEMORAL SHEATH & FEMORAL CANAL
11
Femoral sheath
• Funnel shaped sleeve of fascia covering upper 4cm of
femoral vessels.
• Continuation of fascia tranversalis.
• It has 3 compartments.
a. Lateral or arterial compartment.
b. Intermediate or venous compartment.
c. Medial or lymphatic compartment (femoral canal)
Femoral canal
This is a medial compartment of femoral sheath. Upper part
of canal called femoral ring.

12. ADDUCTOR CANAL (HUNTER’S/SUBSARTORIAL CANAL)
• It is an intermuscular space situated on medial aspect of the middle third of thigh.
• Extend from the apex of femoral triangle to tendinous opening of adductor.
Boundaries
• Anterior wall: adductor lamina & Sartorius.
• Lateral wall: vastus medialis.
• Posteriomedial wall: adductor longus & magnus
Contents
• Saphaneous nerve, nerve to vastus medialis.
• Femoral vessels
• Lymphatic vessels
12

13. MUSCLES OF ANT. COMPARTMENT OF THIGH
• Anterior compartment has following muscles.
I. Sartorius.
II. Quadriceps femoris.
a. Rectus femoris.
b. Vastus medialis.
c. Vastus lateralis.
d. Vastus intermedius.
13

14.  Sartorius
14
• Origin
Anterior superior iliac spine.
• Insertion
Medial surface of proximal tibia.
• Innervation
Femoral nerve.
• Action
Adducts & lateral rotates the thigh.
Flexes leg at knee joint.

15.  Rectus femoris
• Origin
Anterior inferior iliac spine & margin of acetabulum.
• Insertion
Base of patella
• Innervation
Femoral nerve
• Action
Extends knee
15

16.  Vastus lateralis
16
• Origin
Lateral lip of line aspera, greater trochanter, gluteal tuberosity
& intertronchanteric line.
• Insertion
Lateral part of base of patella.
• Innervation
Femoral nerve.
• Action
Extends knee.

17.  Vastus medialis
• Origin
Medial lip line aspera & intertrochanteric line.
• Insertion
Medial side of patella.
• Innervation
Femoral nerve.
• Action
Extends knee joint & locks the knee during extension.
17

18.  Vastus intermedius
• Origin
Anterior & lateral surface of shaft of femur.
• Insertion
Base of patella.
• Innervation
Femoral nerve.
• Action
Extends knee joint

20. BLOOD SUPPLY ANT. THIGH
FEMORAL ARTERY
• This is the chief artery of lower limb. It is a continuation of externl iliac artery.
• Begins behind inguinal ligament. It run first in femoral triangle and
then in adductor canal where it continuous as popliteal artery.
Branches
• Superficial branches
a. Superficial external pudendal artery
b. Superficial epigastric artery
c. Superficial circumflex illiac artery
• Deep branches
a. Profunda femoris artery
b. Deep external pudendal artery
c. Muscular branches 20

21. 21

22. Profunda femoris artery
• The largest branch of femoral artery in thigh. Originates from lateral side of
femoral artery in femoral triangle.
• It has medial circumflex femoral artery.
• Lateral circumflex femoral artery.
22

23. FEMORAL VEIN
• It is continuation of popliteal vein.
Popliteal vein run upward through
adductor canal to become a
popliteal vein.
• Femoral vein receives,
a. Great saphenous vein.
b. Lateral & medial circumflex
femoral veins.
23

24. Femoral Nerve
• Femoral nerve is a chief nerve of anterior
thigh.
• It is formed by the dorsal division of anterior
primary rami of L2,L3 & L4 spinal nerve.
• It enters in thigh behind inguinal ligament just
lateral to femoral artery.
• It gives branches in femoral triangle
I. Muscular branch (supply to muscles of ant.
Thigh)
II. Cutaneous branch (supply to skin of front of
thigh)
III. Articular branch (to hip & knee joint)
