2. Overview of Hip/Lower Extremity Blocks Flashcards
how many nerves supply the leg
4
major nerves to leg
- femoral
- lateral femoral cutaneous
- obturator
- sciatic
femoral nerve innervation
anterior thigh and knee
lateral femoral cutaneous innervation
upper lateral thigh
hip
obturator nerve innervation
medial thigh
hip joint
knee joint
sciatic nerve innervation
posterior thigh
posterior knee
everythin below the knee except the medial portion of the lower leg
which nerve is a branch of the femoral nerve
saphenous
saphenous innervation
medial lower leg, ankle, foot
branches of the sciatic nerve
- deep peroneal
- superficial peroneal
- tibial
- sural
largest terminal branch of lumbar plexus
femoral nerve
dose the saphenous nerve have motor or sensory?
sensory only
longest spinal nerve in the body
sciatic nerve
which nerve provides motor innervation to the leg
sciatic
femoral
branches of tibial nerve
posterior tibial
sural
branches of common peroneal nerve
superficial peroneal
deep peroneal
saphenous nerve
superficial peroneal nerve
deep peroneal nerve
posterior tibial nerve
sural nerve
motor component of femoral nerve
quads
leg/knee extension
which blocks work for femoral nerve?
femoral nerve block
fascial iliaca block
which blocks for lateral femoral cutaneous?
fascia iliaca is better than femoral + fascial iliaca
which blocks for obturator nerve?
femoral and fascia iliaca are not reliable for obturator nerve
femoral and fascia iliaca block what nerves?
femoral (reliable)
saphenous (reliable)
lateral femoral cutaneous (reliable)
obturator (not reliable)
which lower leg nerve block uses less volume of anesthetic?
femoral nerve block
how much volume does femoral block use?
20 mL
FICB (fascia iliaca) is more ________
lateral
how much volume for FICB?
30-40 mL
