Adductor Canal & Popliteal Fossa (Viva)

ADDUCTOR CANAL


Q.1 What are the boundaries of the adductor canal?

Posteriorly:

  • Adductor longus above and
  • Adductor magnus below.

Anteriorly:

  • Vastus medialis.

Medially:

  • Sartorius which lies on a fascial sheet extending across the anterior and posterior walls.

 

Q.2 What is the extent of the adductor canal?

It extends from the apex of the femoral triangle to the tendinous opening in the adductor magnus.

 

Q.3 What are the contents of the adductor canal?

  • Femoral artery.
  • Femoral vein.
  • Descending the genicular branch of the femoral artery.
  • Saphenous nerve.
  • Nerve to vastus medialis.
  • Obturator nerve.

 

POPLITEAL FOSSA


Q.1 What are the boundaries of the popliteal fossa?

Superolaterally: Biceps femoris tendon.

Superomedially: Semimembranosus and Semitendinosus.

Inferomedially: Medial head of gastrocnemius.

Inferolaterally: Lateral head of gastrocnemius and plantaris.

 

Q.2 Which structures form the floor of the popliteal fossa?

From above downwards:

  • The popliteal surface of the femur
  • The capsule of the knee joint
  • Popliteal fascia.

 

Q.3 What is the relationship between the tibial nerve and popliteal vessels in the popliteal fossa?

From superficial to deep lie, the tibial nerve, popliteal vein, and popliteal artery. The popliteal artery is crossed by the popliteal vein and tibial nerve posteriorly from the lateral to medial side.

 

Q.4 What are the contents of popliteal fossa?

  • Popliteal artery and its branches.
  • Popliteal vein and its tributaries.
  • Tibial nerve and its branches.
  • Common peroneal nerve and its branches.
  • Genicular branch of obturator nerve.
  • Posterior cutaneous nerve of thigh.
  • Popliteal lymph nodes.
  • Fat.
