3. HISTORY OF THE ADDUCTOR CANAL
Surgeon John Hunter utilized this region as the
site for compression of femoral vessels- by
applying the tourniquet against the bony
resistance of linea aspera to arrest the bleeding
in the operation of
- aneurysm of popliteal vessels or during the
amputation of lower limb below the knee, hence
it is called as HUNTERS CANAL.

7. APPLIED ANATOMY OF ADDUCTOR CANAL
• Penetrating injuries at the canal will
damage the femoral artery, sectioning of
the both the divisions of obturator nerve
and saphaneous branch of femoral nerve.
Manifestations seen are:-
• Loss of blood supply below the knee
region.
• Loss of cutaneous sensation on medial
side of thigh.
• Loss of cutaneous sensation on medial
border of the foot upto great toe.
• Loss of proprioception of knee joint due
to sectioning of genicular branch of
obturator nerve.
8. ANEURYSM OF POPLITEALARTERY
• In the aneurysm of
popliteal artery, the
surgeons ligated the
femoral artery in
subsartorial canal.
• The fibrous roof is
incised to enter the canal.
13. APPLIED ANATOMY-
• 1) Referred pain- In the diseases of hip joint, referred pain is there
along the medial side of thigh or to knee jt, due to common nerve
supply of obturator nerve.
• 2) Surgical division of obturator nerve is essential to relieve the
spasm of the adductor muscles in spastic paralysis.
• 3) In inflammation of ovary, localized peritonitis irritates the
obturator nerve. Pain is referred in such condition to the hip, knee or
inner side of thigh.
• 4) In case of spastic paraplegia obturator nerve is cut in order to
ensure better perineal care.
• 5) Damage to obturator nerve leads to paralysis of adductor muscles
of the medial compartment of thigh and sensory loss on the medial side
of the skin of the thigh.
