Adductor Canal

Question 1

Anatomical location

Answer 1

Narrow conical tunnel located in thigh

From apex of femoral triangle to adductor magnus

Question 2

Anterior border

Answer 2

Sartorius

Question 3

Lateral border

Answer 3

Vastus medialis

Question 4

Posterior border

Answer 4

Adductor longus

Adductor magnus

Question 5

Apex

Answer 5

Adductor hiatus (gap between adductor and hamstring attachments of adductor longus)

Question 6

Contents

Answer 6

Femoral artery
Femoral vein
Nerve to vastus medialis
Saphenous nerve

Question 7

Adductor canal block

Answer 7

Local anaesthetic is administered in the canal to block saphenous nerve
Sometimes blocks nerve to vastus medialis
Provides sensory anaesthesia for procedures involving distal thigh and femur, knee and lower leg on the medial side

Question 8

Locate saphenous nerve

Answer 8

Use sartorius and femoral artery as anatomical landmarks

Question 9

Adductor canal compression syndrome

Answer 9

Entrapment of the neurovascular bundle within the canal
Usually caused by hypertrophy of adjacent muscles eg. vastus medialis
Most common in young males
May present with claudication due to occlusion of femoral artery
Or neurological symptoms due to entrapment of saphenous nerve
