ANATOMY DEPARTMENT

2. INTRODUCTION
 Also known as HUNTER`S
CANAL or SUBSARTORIAL
CANAL.
Define as:
Intermuscular space situated on
the medial side of the middle one
third of the thigh.

3.  EXTENT:
from apex of femoral
triangle (above) to the tendinous
opening in the adductor magnus
muscle.
 SHAPE:
Is triangular in cross section

4. BOUNDARIES:
ANTERIOR WALL: vastus medialis
POSTERIOR WALL / FLOOR: above- adductor longus
below – adductor magnus
MEDAIAL WALL / ROOF: a fibrous membrane joining the
anterior and posterior wall. It is over lapped by ssartorius.

6. SUB SARTORIAL PLEXUS OF NERVE
 Nerve plexus is formed on the roof of the canal under cover of
sartorius muscle and so known as sub sartorial plexus.
 Nerves included:
MEDIAL CUTANEOUS NERVE OF THIGH branches
SAPHENOUS NERVE
OBTURATOR NERVE (anterior division)
 It supplies the over lying fasacia lata and neighbouring skin

7. CONTENTS OF ADDUCTOR CANAL
a) Femoral artery and its branches ( muscular and genicular
descending branch)
b) Femoral vein
c) Nerves : Saphenous nerve
Nerve to the vastus medialis
Two division of obturator nerve

11. CLINICAL SIGNIFICANCE
For various surgical procedures femoral canal is exposed through adductor
canal.
After ligature of femoral artery the collaterals are developed by anastomosis
between;
descending branch of lateral circumflex femoral and descending genecular
arteries
Fourth perforating artery and muscular branches of popliteal artery
