Anatomical structure and components of the femoral triangle
Floor of the femoral triangle
The floor of the femoral triangle consists of key anatomical structures including the iliopsoas, pectineus, and adductor longus muscles, which provide support and facilitate movement of the hip joint.

Floor of the Femoral Triangle
The femoral triangle is an important anatomical landmark in the upper thigh, bordered by the inguinal ligament, sartorius muscle, and adductor longus muscle. Its floor is composed of several key structures that provide support and separation between deeper vascular and neural elements.
Key Components of the Floor
- Iliopsoas Muscle: Positioned laterally, this muscle plays a crucial role in hip flexion and stability.
- Pectineus Muscle: Located medially, it assists in hip adduction and flexion.
- Adductor Longus Muscle: Forms the medial boundary and contributes to thigh movement.
- Fascia Covering: The floor is reinforced by deep fascia, particularly the fascia lata, which helps maintain structural integrity.
Clinical Significance
The femoral triangle is an area of vital importance for clinical assessments. It houses the femoral artery, vein, and nerve, making it a common site for vascular access and nerve evaluation. Injuries or pathological conditions affecting this region can impact mobility and circulation in the lower limb.
