Organization of the Leg Flashcards
deep fascias of the leg
crural fascia
interosseous membrane
retinacula
tendon (synovial) sheaths
crural fascia
continuous w/ the fascia lata
attaches to the anterior and medial borders of the tibia
incision would be made here to relieve compartment syndrome
interosseous membrane
connects the shafts of the tibia and fibula
retinacula
3
extensor
flexor
fibular
compartments of the leg
anterior
lateral
posterior
compartment syndrome
swelling from injuries that can lead to loss of blood flow and amputation of the lower leg
can happen from an accident or a surgery
anterior compartment nerve rule
deep fibular nerve
what action do muscles in the anterior compartment conduct
ankle dorsiflexion and tow extension
what muscles are in the anterior compartment
tibialis anterior
extensor digitorum longus
extensor hallucis longus
fibular tertius (not always present)
lateral compartment nerve rule
superficial fibular nerve
what action do the muscles in the lateral compartment conduct
eversion
what are the muscles in the lateral compartment
fibularis longus
fibularis brevis
nerve rule of the posterior compartment
tibial nerve
what actions do the muscles in the posterior compartment conduct
plantar flexion and toe flexion
what are the groups w/in the posterior group
superficial and deep groups
