anatomy of anterior compartment of thigh

2.  Skin – Thick and tough on the exposed
surfaces with more friction (buttock, lateral
aspects of thigh and leg, sole of foot)
 Superficial fascia – loose areolar tissue, fat,
cutaneous nerves, great saphenous vein and
tributaries, cutaneous branches of femoral
artery and inguinal lymph nodes with vessels.

3.  Lateral femoral cutaneous nerve – direct
branch of lumbar plexus
 Intermediate and medial femoral cutaneous
nerves and saphenous nerve – branches of
femoral nerve
 Branch from anterior division of obturator
nerve
 Skin over femoral triangle is supplied by
- Ilio inguinal nerve
- Femoral branch of genito-femoral nerve

5. Three sets of veins
 Superficial veins – lie in the superficial
fascia(Great and small saphenous veins)
 Deep veins – surrounded and supported by
powerful muscles and enclosed in tube of thick
non elastic deep fascia and the accompany
arteries
 Perforating veins – communicate between deep
and superficial veins. They are valved and allow
blood flow from superficial to deep only

7.  It’s the longest vein in the body
 Begins as a continuation of media end of
dorsal venous arch of the foot supplemented
by medial marginal vein – passes upward in
front of medial malleolus – medial surface of
tibia – postero medial aspect of knee joint –
posterior to patella – medial side of thigh –
Saphenous opening 3 cm below and lateral to
pubic tubercle

8.  Posterior arch vein
 Anterior leg veins
 Veins from calf which will communicate with
small Saphenous vein
 Antero lateral vein
 Postero medial vein(accessory Saphenous)
 Superficial epigastric
 Superficial circumflex liac
 Superficial external pudental
 Thoraco-epigastric
 Deep external pudental

9.  Sartorius
 Quadriceps
 Vastus Medialis
 Vastus Intermedius
 Vastus Lateralis
Articularis Genu

16.  SUPERFICIAL EPIGASTRIC ARTERY
 SUPERFICIAL CIRCUMFLEX ILIAC ARTERY
 SUPERFICIAL EXTERNAL PUDENTAL
 DEEP EXTERNAL PUDENTAL
 MUSCULAR BRANCHES
 PROFUNDA FEMORIS ARTERY
- MEDIAL CIRCUMFLEX
- LATERAL CIRCUMFLEX
- PERFORATING BRANCHES
 DESCENDING GENICULAR ARTERY

25.  Ligature of femoral artery
 Femoral nerve block
