Lecture 18: Femoral Triangle

Question 1

boundaries

Answer 1

• sup: inguinal lig
• medial: lateral border of adductor longus
• lateral/inf: sup border of sartorius
• floor: iliopsoas (lat) and pectineus (med)
• roof: skin and fascia (fascia lata; cribriform) of thigh

Question 2

retroinguinal space

Answer 2

• between inguinal lig and hip bone
• allows passage of femoral a/v/n from pelvis to femoral triangle
• these structures are easy to injure bc they’re close to the skin

Question 3

iliopectineal arch

Answer 3

divides retroinguinal space into lateral and medial compartments

Question 4

lateral (muscular) compartment contents

Answer 4

• iliacus

- femoral n.

Question 5

medial compartment contents

Answer 5

• femoral sheath

- pectineus

Question 6

femoral sheath

Answer 6

contains femoral artery and vein and inguinal lymph nodes in femoral (adductor) canal

Question 7

adductor canal contents

Answer 7

• femoral artery and vein

- saphenous nerve (cutaneous branch of femoral n) that provides cut innervation to lower leg
