foot/ankle Flashcards
what major muscle is responsible for foot eversion?
peroneus longus
what major muscle is responsible for plantarflexion?
gastroc/soleus
what major muscle is responsible for dorsiflexion?
anterior tibialis
what major muscle is responsible for foot inversion?
posterior tibialis
this is what distal connection of the tibia to the fibula
syndesmosis joint (made up of AITFL, PITFL, and transverse ligament)
nerve responsible for hip flexion
L2
nerve responsible for medial hamstring reflex
L5
Nerve responsible for cremasteric and Babinski reflexes
S2-S4
positive anterior drawer sign of the ankle means what?
ATF sprain (anterior talofibular ligament)
positive findings on the talar tilt test indicate what?
calcaneofibular ligament tear (lateral….pain with inversion)
In the _______ test, the patient is prone with feet dangling over the edge of the bed. Provider squeezes the gastroc and looks for the foot to ________. If this does not happen, it may indicate rupture of the ___________
Thompson test, plantarflex (normal), absence = Achilles tendon rupture
during this test, the patient will experience reproduction of pain at a point away from the site of pain and suggests a fracture of syndesmotic injury
compression test
This view of the ankle in plain film is taken at 15 degrees internal rotation
Mortise view
This view allows us to see tib/fib/talar joint
mortise
What tendon is exclusively lateral ankle?
peroneal
whenever you suspect an ankle sprain/inversion injury and there’s ttp of the peroneal nerve, what must you ALWAYS do?
palpate the insertion at the 5th metatarsal for avulsion/fx
How do you tx ankle sprain? (medial or lateral)
1) walking boot
2) PT
which ankle ligament is strongly a/w the medial malleolus?
deltoid ligament
If you suspect a medial ankle sprain/eversion injury and there’s ttp to the deltoid ligament, what must you ALWAYS do?
palpate the proximal fibula for avulsion/fx
Your patient has pain with dorsiflexion and resisted plantar flexion. There is ttp over the Achilles tendon. How will you treat?
Achilles tendonitis, tx with
1) walking boot with heel lift,
2) PT
3) NTG patch
How do you know if it’s Achilles tendonitis vs Achilles rupture?
1) acute onset
2) defect/gap
3) THOMPSON TEST
