Anterior Compartment Of Thigh Flashcards
Injury to femoral nerve
Paralysis of quadratus femoris
Loss of sensation in medial and anterior aspect of thigh.
Meralgia paresthetica
The lateral cutaneous nerve is compressed as it passes through the inguinal ligament.
Causes pain and parasthesia in upper lateral aspect of thigh.
Treatment: surgical division of inguinal ligament and releasing nerve from compression.
Largest and longest superficial vein of lower limb
Great saphenous vein
Course of long saphenous vein
It begins at the medial aspect of dorsum of foot.
Moves upward infront of medial malleolus.
It enters the medial aspect of thigh by going behind the knee.
It the moves upward and opens into saphenous opening.
It pierces cribiform fascia and opens into femoral vein.
Before piercing cribriform fascia it receives 3 tributaries : superficial epigastric vein, superficial external pudendal vein and superficial circumflex iliac vein
Superficial inguinal lymph nodes
Two sets: horizontal and vertical.
Two sets arranged in T shape.
Upper horizontal again divided into upper lateral and upper medial group.
Drainage of upper lateral group of superficial lymph node
Drain from lower lateral part of infraumblical region of abdomen
Drainage of upper medial superficial lymph node
Drains from lower medial part of infraumblical region of abdomen
Where are lower vertical group of superficial inguinal lymph node present.
Lie along upper part of long saphenous vein.
What is iliotibial tract
Fascia Lata thickens in the lateral aspect to thigh to form 5 cm wide strong fibrous band
Muscles anchored by ilitibial tract
The upper part of iliotibial tract splits and anchors tensor fascia Lata muscle and receives most of the tendons of gluteus maximus.
Attachments of iliotibial tract.
Superficial lamina - tubercle of iliac crest
Deep lamina - blend with lateral aspect of capsule of hip joint.
Lower part- lateral condyle of tibia in Gerdy’s tubercle.
Rectus femoris
Origin:
Straight head upper part of ASIS
Reflected head from groove above acetabulum
Insertion:
Base of patella
Nerve:
Femoral nerve
Action:
Flexion of hip joint and extension of knee joint
Vastus lateralis
Origin
Greater trochanter
Lateral lip of linea aspera
Insertion

Nerve
Femoral nerve
Action
Extension of knee joint
Vastus medialis
Origin
Medial lip of linea aspera
Insertion

Nerve
Femoral nerve
Action
Extension of knee joint
Articularis genu
Origin
Lower part of anterior surface of femur
Insertion
Synovial membrane of knee joint
Nerve
Femoral nerve
Action
Pulls up the synovial membrane of knee joint during extension
Sartorius
Origin
ASIS
Insertion
Medial surface of shaft of tibia
Nerve
Femoral nerve
Action
Flexion of hip and knee joint
Lateral rotation of thigh
What is femoral triangle
Triangular area in the upper front of thigh
Boundaries of femoral triangle
Medial: medial border of adductor longus
Lateral: medial border or sartorius
Base: inguinal ligament
Apex: point of meeting of sartorius and adductor longus
Floor: from lateral to medial
Iliacus
Tendon of psoas major
Pectineus
Adductor longus
Roof: skin and superficial fascia and deep fascia
Contents of femoral triangle
Femoral artery
Femoral vein
Femoral nerve
Deep inguinal lymph nodes
Lateral cutaneous nerve of thigh
