  1. Dr. SREEKANTH THOTA DEPARTMENT OF ANATOMY Lower limb WINDSOR UNIVERSITYSCHOOL OF MEDICINE

  2. Femoral Triangle • This is a clinically important triangular subfascial space in the superomedial one-third part of the thigh.

  3. The femoral triangle is bounded • Superiorly :Inguinal ligament that forms the base of the femoral triangle. • Medially:Adductor longus. • Laterally :Sartorius. • Apex is where the lateral border of the sartorius crosses the medial border of the adductor longus. • Roof :Fascia lata, subcutaneous tissue, and skin. • Floor :Iliopsoas laterally and the pectineus medially.

  4. Femoral Triangle Inguinal ligament Iliopsoas Pectineus Sartorius Adductor longus Adductor longus

  5. The contents of the femoral triangle, from lateral to medial • Femoral nerveand its (terminal) branches. • Femoral sheath and its contents: • Femoral artery • Femoral vein • Deep inguinal lymph nodes • NAVaL(Lateral to medial)

  6. Femoral Sheath The sheath is formed by an inferior prolongation of transversalis and iliopsoas fascia from the abdomen/greater pelvis. The femoral sheath is subdivided internally into three compartments. 1. Lateral compartment :Femoral artery. 2. Intermediate compartment :Femoral vein. 3. Medial compartment:Femoral canal

  7. Femoral canal The femoral canal is the smallest of the three compartments. It is short (approximately 1.25 cm). The base of the femoral canal, formed by the small (approximately 1 cm wide) proximal opening at its abdominal end, is the oval femoral ring.

  8. Femoral Hernia Femoral Hernias are much more common in women, but can occur in men.  A weakness in the lower groin allows an intestinal sac to drop into the femoral canal.

  9. Femoral Nerve Cutaneous nerve: saphenous nerve and medial and intermediate cutaneous nerve of thigh. Motor nerves: Quadriceps femoris muscles (rectus femoris, vastuslateralis, vastusintermedius, and vastusmedialis muscles) and the sartorius muscle

  10. Femoral Artery Branches Deep artery of thigh OR Profundafemoris artery 1.Medial circumflex femoral 2.Lateral circumflex femoral

  11. Adductor Canal, subsartorial canal; Hunter canal Approximately 15 cm. It extends from the apex of the femoral triangle, where the sartorius crosses over the adductor longus, to the adductor hiatus in the tendon of the adductor magnus. Contents: Femoral artery and vein, the saphenous nerve, and the nerve to vastusmedialis.
