2. OBJECTIVE
• Introduction to lower limb
• Compartments of thigh
• Front of thigh
• Superficial fascia and Deep fascia
• Contents in front of thigh
• Muscles
• Vessels
• Nerve
• Femoral triangle
• Femoral sheath
• Adductor canal
• Applied aspects
4. COMPARTMENTS OF THIGH
• Anterior compartment
(Front of thigh )
• Medial compartment
• Posterior compartment
( back of thigh)
5. FRONT OF THIGH
• Between hip joint and knee joint
• Surface landmarks
• Anterior superior iliac spine
• Pubic tubercle
• Midinguinal point
• Midpoint of inguinal ligament
• Greater trochanter
• Medial and lateral condyles of femur and
tibia
• Adductor tubercle
• Patella
• Tibial tuberosity
6. SUPERFICIAL FASCIA
• 2 layers
• Superficial fatty layer
• Campers fascia
• Deep membranous layer
• Scarpa’s fascia
Contains cutaneous nerves, vessels ,superficial inguinal lymphnodes,
great saphenous vein
8. DEEP FASCIA
• Deep fascia - Fascia lata
• Holdens line
• Scarpa’s fascia attached to fascia lata in a
horizontal line from pubic tubercle
Fascia lata
9. MODIFICATION OF DEEP FASCIA
• Saphenous opening
• Oval opening in fascia lata
• Lies 4cm below and 4 cm lateral to
pubic tubercle
10. • Iliotibial tract
• Thickening of fascia lata on
the lateral aspect of thigh
• Above - enclose gluteus
maximus and tensor fascialata,
gluteal aponeurosis
• Below- attached to lateral
condyle of tibia
• Stabilizes the knee
16. RECTUS FEMORIS
• Origin - Ilium
• Straight head -Anterior inferior iliac spine
• Reflected head -Groove above acetabulum
• Insertion
• Base of patella
• Nerve supply
• Posterior division of femoral nerve
• Action
• Extends the knee, flexes the hip
17. VASTUS LATERALIS
• Origin
• Intertrochonteric line , greater trochanter, gluteal
tuberosity, linea aspera
• Insertion
• Into the tendon of rectus femoris , lateral part of base of
patella , lateral border of patella
• Nerve supply
• Posterior division of femoral nerve
• Action
• Extension of knee joint
18.
19. VASTUS MEDIALIS
• Origin
• Intertrochanteric line , spiral line , medial lip of linea aspera, upper
2/3rd of medial supracondylar line, medial intermuscular septa
• Insertion
• Into the tendon of rectus femoris, medial part of base of patella, upper
2/3rd of medial border of patella
• Nerve supply
• Posterior division of femoral nerve
• Action
• Extension of knee joint
20.
21. VASTUS INTERMEDIUS
• Origin
• Anterior and lateral aspect of upper 3/4th of femur
• Insertion
• Base of patella deep to rectus femoris
• Nerve supply
• Posterior division of femoral nerve
• Action
• Extension of knee joint
22.
23. ARTICULARIS GENU
• Detached part of vastus intermedius
• Origin
• Anterior surface of lower part of femur
• Insertion
• Upper part of synovial membrane of knee
joint
24. Nerve supply
Nerve to vastus intermedius
Action
Pulls up the synovial membrane during
knee extension
25. SARTORIUS
• Longest muscle of the body
• Origin
• Anterior superior iliac spine
• Insertion
• Upper part of medial surface
of shaft of tibia
Sartorius
26. • Nerve supply
• Anterior division of femoral nerve
• Action
• flexion of hip and knee joint
• Adducts and rotates the thigh laterally
• Tailor’s muscle
27. TENSOR FASCIA LATA
• Lies between gluteal region and upper
part of front of thigh
• Origin
• Outer lip of iliac crest
• From ASIS to iliac tubercle
• Insertion
• Iliotibial tract
28. • Nerve supply
• Superior gluteal nerve
• Action
• Abducts hip joint
• Maintain extended position of
knee joint through iliotibial tract
34. • Roof
• Superficial branches of femoral
artery and accompanying veins
• Great saphenous vein
• Superficial inguinal lymphnodes
• Femoral branch of genitofemoral
nerve
• Branches of ilioinguinal nerve
35. CONTENTS
• Femoral artery and its branches
• Femoral vein and its tributaries
• Femoral nerve
• Deep inguinal lymphnodes
• Lateral cutaneous nerve of thigh
