T12 - L4
spinal nerves in Femoral nerve
L2 - L4
- femoral artery
- nerve
- vein
- anterior superior iliac spine
- inguinal ligament
- sartorius
indications for femoral nerve block
thigh, femur, and knee surgery
amount of LA in femoral block
10-20 mL
Femoral Block

Indications for Adductor Canal block
knee arthroscopy or replacement, ACL repair, lower leg surgery involving saphenous nerve
Advantage of adductor canal over femoral block
only sensory block, no motor fibers involved
adductor canal block anesthetizes the ____ nerve
saphenous
adductor canal is bounded by which 3 muscles
sartorius, vastus medialis, and adductor longus
Indications for Saphenous nerve block
saphenus vein harvesting
or
supplemental for medial foot/ankle surgery in combination with sciatic nerve block
volmue of LA in saphenous nerve block
5 - 10 mL
the saphenus nerve is the terminal sensory branch of the _____ nerve
femoral nerve
innervation of saphenous nerve
medial leg
Saphenous nerve block

spinal nerves in Sacral plexus
L4 - S3
the sciatic nerve lies across which muscles
piriformis
sciatic and femoral nerve blocks will often miss _____ nerve and lateral percutaneous
obturator
(do sciatic and fascia illiaca)
which nerve causes dorsiflexion
common peroneal nerve
which nerve causes plantarflexion
tibial nerve
muscle boundaries of the politeal fossa
semi-tendenosis/membranosus and bicep femoris
the sciatic nerve splits into _____ and ____
tibial and common peroneal
}Which is most appropriate combination of nerve blocks for knee arthroscopy with a tourniquet:
