adductor/hunter's canal Flashcards
(32 cards)
Q
A
Where is the adductor canal located?
In the middle 1/3 of thigh, from femoral triangle apex to adductor hiatus in adductor magnus
What forms the roof of adductor canal?
Sartorius muscle
What forms the anterolateral wall?
Vastus medialis muscle
What forms the posteromedial wall?
Adductor longus and magnus muscles
What are the contents of adductor canal?
Femoral artery, femoral vein, saphenous nerve, nerve to vastus medialis
What important transition happens at adductor hiatus?
Femoral artery → popliteal artery
Why is adductor canal block preferred for knee surgery?
Blocks saphenous nerve while preserving quadriceps function (unlike femoral nerve block)
What nerve is in adductor canal but not femoral triangle?
Saphenous nerve (terminal branch of femoral nerve)
What clinical condition results from saphenous nerve entrapment?
Medial knee pain (mimics pes anserine bursitis)
What mnemonic helps remember adductor canal boundaries?
SVA: Sartorius (roof), Vastus medialis, Adductors (walls)
What artery supplies the adductor canal region?
Descending genicular artery (branch of femoral artery)
How does adductor canal relate to popliteal aneurysms?
Femoral artery becomes popliteal artery here - transition zone for aneurysms
What’s the key difference between femoral triangle and adductor canal contents?
Femoral triangle contains femoral nerve; adductor canal contains saphenous nerve
Why is vastus medialis important in adductor canal anatomy?
Forms anterolateral wall; innervated by nerve to vastus medialis in the canal
What happens to the femoral vein in this region?
Receives great saphenous vein near adductor hiatus
