Leg triangle

A thigh triangle ( Latin: Trigonum femorale , Scarpa triangle after Antonio Scarpa ) is a triangular area on the inside of the thigh immediately below the groin . In the thigh triangle run directly under the skin and thigh fascia:

• Femoral artery and its proximal branches
• Femoral vein
• Femoral nerve
• Saphenous nerve

The limits of the leg triangle in humans are :

• proximal: inguinal ligament ( ligamentum inguinale )
• lateral: sartorius muscle
• medial: adductor longus muscle
• dorsal (floor): Musculus iliopsoas and Musculus pectineus

In the quadruped mammals it is limited by:

• above: inguinal ligament ( ligamentum inguinale )
• cranial: sartorius muscle
• caudal: pectineus muscle

The thigh gap continues from the thigh triangle as a vascular-nerve-street.
