The femoral triangle


The femoral triangle is a hollow region located in the supero-medial part of the anterior thigh. It is an easily acessable area through which multiple neurovascular structures pass through. It is also known as"scarpa's triangle" and "femoral trigone".


  • Femoral Nerve- Which innervates the anterior compartment of the thigh
  • Femoral Artery- Arterial supply for majority of the lower limb
  • Femoral Canal-Contains lymph nodes and vessels
  • Femoral Vein-  The great saphenous vein drains into the femoral vein within the triangle
  • Superfical and deep inguinal lymph nodes


The femoral triangle has three borders namely

  • Superior border- which is formed by the Inguinal Ligament
  • Lateral border- which is formed by the medial border of the Sartorius Muscle 
  • Medial- which is formed by the medial border of the Adductor Longus   

Floor and roof

The floor of the femoral triangle is comprised of the Adductor Longus, pectineus, psoas major and illiacus muscles. The shape of the floor is gutter shaped since all the muscles forming the floor pass to the posterior aspect of the femur.

The roof of the femoral triangle consists of skin, superficial and deep fasica of the the thigh.
