Deep fascia of the thigh
• Iliotibial tract
laterally the deep fascia forms a thick
band, from the iliac tubercle to the
lateral condyle of tibial.
• The fascia lata sends intermuscular septa
to the linea aspera of the femur. These
separate the thigh into three
compartments each of which contains a
group of muscles, the vessels and the
nerves.
Femoral Triangle: Location & Boundaries
• It is a deep hollow in the Upper
third of front of thigh inferior to
the inguinal ligament
Boundaries
• Base: Inguinal ligament
• Medial: Medial border of the
adductor longus muscle
• Lateral: Medial border of the
sartorius muscle
• Floor: (from media to lateral)

•
adductor longus
Pectineus
Psoas major

• Roof: Skin, superficial & deep

Contents
From lateral to medial:
1. Femoral nerve & its branches
2. Femoral artery
3. Femoral vein
4. Lymphatic vessels and some
deep inguinal lymph nodes
5. Lateral femoral cutaneous nerve
6. Femoral branch of genitofemoral
nerve
The femoral artery, femoral vein
and the lymph nodes lies within the
fascial envelope, the Femoral
sheath.
