Femoral Triangle Notes:
Introduction:
Femoral triangle is a triangular depression on the front of upper one 3rd of thigh immediately below Inguinal ligament.
Boundaries:
•Laterally: medial border of sartorius
•Medially: medial border of adductor longus
•Base: inguinal ligament.
•Apex: [directed downwards] point where medial & lateral boundaries cross
Roof:
•Skin
•Superficial frascia
•Deep fascia including cribriform fascia
Floor:
•Medially adductor longus & pectineus •Laterally psoas major & iliacus
Contents:
1,Femoral artery & its branches:
3 superficial & 3 deep branches
Superficial:
•Superficialexternal pudendal
•Superficial circumflex iliac
•Superficial epigastric
Deep:
•Profunda femorts
•deep external pudendal •Muscular branches
2,Femoral vein & it's tributaries:
•Vein accompanies femoral artery
•Vein medial to artery at base of triangle.
•Vein is posteromedial to artery at apex of triangle •Vein receives- great sephanous vein. circumflex vein corresponding to femoral Artery
3,Femoral sheath:
Encloses upper 4 cm of femoral vessels.
4,Nerves:
•Femoral nerve- lies lateral to femoral artery.outside femoral sheath.
•Nerve to pectineus- arises from femoral nerve just above inguinal ligament.
•Lateral cutaneous nerve of thigh-Crosser lateral angle of triangle Runs on lateral side of thigh & divides into blanches. anterior & posterior branches
•Deep inguinal lymph nodes-Lies deep to the deep fascia. These lies medial to upper part of femoral vein & receive lymph from superficial inguinal lymph nodes from glans penis or clitoris & deep lymphatics of lower limb.
Clinical anatomy:
1.Femoral hernia:
•Femoral canal is an area of potential weakness. in the abdominal wall through which abdominal contents may bulge Out forming femoral hernia.
•It is more common in females because femoral canal is wider.
2,Femoral artery can be compressed at midinquinal point against head of femur or against the superior ramus of pubis to control bleeding from distal part of limb in thigh or leg.
