Flashcards in Femoral canal Deck (11):
What are the borders of the femoral canal?
medial border: lacunar ligament (joins inguinal and pectineal ligament)
lateral border: femoral vein
anterior border: inguinal ligament
posterior border: pectineal ligament, superior rami of pubis & pectineus muscle
superior border: femoral ring (femoral septum CT)
What is contained within the femoral triangle, sheath and canal?
sheath: artery, nerve, vein
What is the opening to the femoral canal and where is it?
superior border - femoral ring
closed by CT layer - femoral septum
What pieces through the femoral septum?
femoral septum (CT layer) - encloses femoral ring
pieced by the lymphatic vessels exiting the canal
What are the contents of the femoral canal?
lymphatic vessels: draining deep inguinal lymph nodes
deep lymph node: lacunar node
Why is there an empty space within the femoral canal?
to allow veins to distend to cope with increased venous return & increased abdominal pressure
Clinical: femoral hernia
bowel protrudes out of the femoral ring
presents as a lump inferolaterally to the pubic tubercle
Which gender is femoral hernia more common in an why?
women due to their wider bony pelvis
What's a strangulated hernia and how can it occur?
tough borders of femoral canal, so can compress hernia (as not very distensible)
causing hernia's blood supply to be compromised
What is a hernia?
an internal part of body pushes though weakness in muscle or surrounding tissue wall
