Femoral triangle Flashcards
What forms the superior border?
Formed by the inguinal ligament, a ligament that runs from the anterior superior iliac spine to the pubic tubercle
what forms the medial border?
Medial border of the adductor longus muscle.
The rest of this muscle forms part of the floor of the triangle.
what forms the lateral border?
Formed by the medial border of the sartorius muscle.
Roof?
Fascia lata
Floor?
pectineus, iliopsoas and adductor longus muscles.
What is the action of the inguinal ligament
The inguinal ligament acts as a flexor retinaculum, supporting the contents of the femoral triangle during flexion at the hip.
What are the contents of the femoral triangle?
Its contents (lateral to medial) are:
Femoral nerve – Innervates the anterior compartment of the thigh, and provides sensory branches for the leg and foot.
Femoral artery – Responsible for the majority of the arterial supply to the lower limb.
Femoral vein – The great saphenous vein drains into the femoral vein within the triangle.
Femoral canal – A structure which contains deep lymph nodes and vessels.
What is the most lateral structure?
Femoral nerve
What are the contents of the femoral sheath?
the femoral artery, vein and canal are contained within a fascial compartment – known as the femoral sheath.
Where can the femoral artery be found?
Mid inguinal point-
Just inferior to where the femoral artery crosses the inguinal ligament, it can be palpated to measure the femoral pulse. The femoral artery crosses exactly midway between the pubic symphysis and anterior superior iliac spine (known as the mid-inguinal point). It is superficial
