Anatomical Features of the Femoral Triangle

Introduction

The femoral triangle is an essential anatomical region located in the upper thigh. It serves as a passage for major neurovascular structures that supply the lower limb.

Anatomical Boundaries

• Superior Boundary: Inguinal ligament
• Medial Boundary: Adductor longus muscle
• Lateral Boundary: Sartorius muscle
• Floor: Formed by iliopsoas, pectineus, and adductor longus muscles
• Roof: Fascia lata and subcutaneous tissue

Contents of the Femoral Triangle

The femoral triangle contains several critical structures arranged from medial to lateral:

1. Femoral Vein: Responsible for venous drainage of the lower limb.
2. Femoral Artery: The major artery supplying blood to the leg.
3. Femoral Nerve: Essential for motor and sensory functions in the thigh.
4. Femoral Canal: Contains lymphatic structures and allows expansion of the femoral vein.

Clinical Significance

The femoral triangle is a crucial site for medical interventions, including femoral artery catheterization and examination of femoral hernias.

Conclusion

Understanding the femoral triangle’s anatomy is vital for surgical procedures and diagnosing conditions related to vascular and nervous structures in the thigh.
