GA 1 Femoral triangle Flashcards
What are the boundaries of the femoral triangle?
Floor: Pectineus and iliopsoas muscles
Roof: fascia Lata
Base: inguinal ligament
Lateral wall: Sartorius
Medial wall: adductor longus
What are the contents of the femoral triangle?
NAVEL towards the navel
- Femoral Nerve
- Femoral Artery
- femoral Vein
- femoral canal (Empty space) with deep inguinal Lymph nodes
Boundaries (description of location)
(femoral triangle)
Subfascial space
triangular depression
superomedial 1/3 thigh
Femoral sheath
funnel-shaped fascial tube (prolongation of transversalis fascia)
encloses proximal parts of femoral vessels and femoral canal. (allows femoral vessels to glide smoothly deep to ingiunal ligament)
ends 4-10 cm distal to inguinal L.
What are the three femoral sheaths and what’s in them?
are any outside of them?

femoral canal
- part of femoral sheath
- contains a few lymph vessesl, loose CT and fat
- allows femoral vein to expand during increased venous return
- extends distally to saphenous opening
- proximal opening 1 cm wide (femoral ring)
Femoral ring
small opening covered by parietal peritoneum (1 cm wide)
(proximal opening to femoral canal)
Femoral Hernia?

Direct vs indirect ingiunal herniae?
???????
Inguinal lymph nodes location and drain?

Superficial inguinal lymph nodes

Deep inguinal lymph nodes

Femoral nerve spinal roots?
L2-L4
Femoral nerve supplies what muscles?
anterior thigh muscles, and hip and knee joints
- Iliacus
- Sartorius
- Quadriceps femoris
- Pectineus
What is the largest branch of lumbar plexus?
Femoral nerve
Where does the femoral nerve start and end?
forms in abdomen within psoas major
enters thigh just lateral to midpoint of inguinal L.
later to femoral vessels.
what is a part of the saphenous nerve?
terminal cutaneous branch
What innervates 1-7?


Which map is this and what causes this particular pattern?

Dermatomes
Limb rotation more lumbar contributions visible anteriorly and sacral posteriorly
What can an Anterior hip dislocation affect?
femoral nerve and lateral femoral cutaneous nerve
What is meralgia paresthetica
Compression of lateral femoral cutaneous nerve as it passes under inguinal ligament causes pain/numbness along lateral thigh
Saphenous nerve

Adductor canal starts and ends?
begins and femoral triangle apex
ends at adductor hiatus
adductor canal contents?
