Leg Anatomy Flashcards
What nerve runs alongside the anterior tibial artery?
Deep peroneal nerve
What structures are found in the anterior compartment?
deep posterior compartement?
Lateral compartment?
Deep peroneal nerve, ant tib artery and vein
Peroneal artery, post tib artery, tibial nerve
superficial peroneal nerve
What are the surgical approaches to the politeal artery?
Medial suprageniculate
Lateral Suprageniculate
Medial infrageniculate
Lateral Infrageniculate
Why is infrageniculate pop better for bypass then proximal pop?
Less affected by atherosclerotic disease
Describe medial infrageniculate pop approach incision?
what structure is nearby incision?
Describe dissection?
How do you gain more proximal exposure from here?
How do you gain distal exposure from here?
What structures are encountered once the dissection is complete?
How do you rout bypass to this level?
Longitudinal incision approx 1cm behind posterior border of the tibia, extending 1/3 distance down from medial tibial condyle
Greater saphenous vein (retract it posteriorly)
Incise crural fascia 1 cm posterior to tibia and extend proximal to semitendinosus muscle. retract medial head of gastroc retracted posteriorly
divide tendons of semitendinosus, gracilis, sartorius
divide tibial attachement of the soleus muscle
popliteal vein (usually paired), popliteal artery, tibial nerve (posteo-med). popliteal branches aren’t important at this level
Throught the abbductor canal, then tunneled posterior to knee between femoral condyles (bring between heads of the gastroc to avoid compression during contraction)
