The front of the thigh Femoral triangle (Scarpa’s triangle) Is a triangular depressed area located in the upper part of the medial aspect of the thigh immediately below the inguinal ligament. Boundaries Superiorly: Medially: The inguinal The medial border of ligament (the base of the triangle) adductor longus muscle Laterally: The medial border of sartorius muscle Floor: gutter shaped from lateral to medial is made by The iliopsoas muscle The pectineus muscle The adductor longus The apex: directed downwards and is formed by the meeting point of Sartorius and adductor longus muscles Contents of the femoral triangle 1-Terminal part of the femoral nerve and its branches. 2- The femoral sheath!!! 3- The femoral artery and its branches. 4- The femoral vein and its tributaries. 5- Deep inguinal lymph nodes 6- femoral branch of genitofemoral nerve 7- lateral cutaneous nerve of the thigh Is a funnel-shaped sleeve of fascia surrounded the femoral artery , vein and the associated lymphatic vessels in the femoral triangle for 2.5 cm below the inguinal ligament. The femoral sheath is formed by a downwards extension of the abdominal fascia. Anterior wall: fascia transversalis Posterior wall: fascia iliaca Two Anterio-posterior septa divide the sheath into 3 compartments: The femoral sheath 1-Lateral compartment (arterial) occupied by the femoral artery and femoral branch of the genitofemoral nerve 2-Intermediate compartment (venous) occupied by the femoral vein 3-Medial compartment (lymphatic) occupied by the lymph vessels (also Called femoral canal ?  Is the small medial compartment for the lymph vessels. 1.3 cm In length. just admits the tip of the little finger. Its upper opening is called the femoral ring. The femoral septum (is a condensation of extraperitoneal tissue), closes the ring. Note: the femoral ring is wider in femals because of their wider pelvis and therefore, femoral hernia is commoner in femals than in males Femoral canal
