    Study Notes

    Femoral Triangle

    • The femoral triangle is a space in the upper third of the front of the thigh
    • The shape of the femoral triangle is inverted triangular
    • The base is directed upwards, the apex is directed downwards and medially
    • Boundaries:
      • Base (directed upwards): Inguinal ligament
      • Medial border: Medial border of the adductor longus muscle
      • Lateral border: Medial border of the sartorius muscle
      • Apex (directed downward): Meeting between the medial and lateral borders. Continuous with the adductor (sub-sartorial) canal
      • Floor:
        • From medial to lateral, comprised of the following muscles:
          • Adductor longus
          • +/- Adductor brevis
          • Pectineus
          • Iliopsoas
      • Roof:
        • The following layers from superficial to deep:
          • Skin
          • Superficial Fascia
          • Deep Fascia (fascia lata) which contains the following structures:
            • Saphenous opening
            • Great Saphenous vein
    • Contents:
      • Lateral to medial:
        • Femoral nerve
        • Femoral artery (surrounded by femoral sheath)
        • Femoral vein
        • Lymphatic vessels
        • Lymph node (deep inguinal L.N.)
        • Femoral canal (structure inside the femoral canal)
    • Apex of the femoral triangle:
      • Points inferiorly
      • Continuous with a fascial canal (adductor canal)
      • Descends medially down the thigh and posteriorly through an aperture in the lower end of the adductor Magnus muscle
      • Opens into the popliteal fossa behind the knee

    Clinical Correlation

    • Vascular Access to the Lower Limb:
      • Many radiological procedures involve catheterization of the femoral artery/vein for access to the contralateral lower limb, ipsilateral lower limb, vessels of the thorax and abdomen, and cerebral vessels
      • The femoral artery is used by cardiologists for coronary angiography and angioplasty
      • Access to the femoral vein allows catheters to access the renal veins, gonadal veins, right atrium, right side of the heart and distal vessels of the pulmonary tree

    Femoral Hernia

    • A femoral hernia passes through the femoral ring medial to the femoral vein
    • It travels through the femoral canal until it reaches the saphenous opening
