Lower Extremity III Flashcards
Anterior lateral malleolus
. Ankle moves more freely into plantarflexion, restriction in dorsiflexion
. Adducts talus causing inf. Displacement of ant. Calcaneus
. Net result is fallen arch
Post. lateral malleolus
. Ankle moves more freely in dorsiflexion
. Restriction in plantarflexion
. Abducts talus causing sup. Displacement of ant. Portion of calcaneus
. Results in high arch
Is supination or pronation easier in ankle joint?
Supination
. Assoc. w/ plantarflexion
Motion of ankle
. Ant.-post. Gliding and rotation about vertical axis in distal tibia-fibular joint
. Dorsiflexion w/ post. Glide and plantarflexion w/ ant. Glide by tibiotalar joint
. Adduction, toeing in, and supination in plantar flexion
. Abduction, toeing out, and pronation in dorsiflexion
Overpronation of foot is associated w/ ____
. Fallen arch or shin splints
Motion of foot
. Adduction from internal rotation of tibia
. Abduction from external rotation of tibia
Ankle drawer test
. Determines if ATF is intact
. Place one hand on calcaneus and other on ant. Distal tibia
. Foot slightly plantarflexed
. Apply ant. Force to calcaneus and talus w. Post. Force to tibia
. Pos. If laxity of calcaneus and talus ant.
Talar tilt test
. Determines if calcaneofibular ligament is torn
. Laxity w/ valgus stress is deltoid issue, w/ varus stress is calcaneofibular laxity
. Patient lies on side w/ foot relaxed and knee flexed, talus tilted from side to side
Cotton test
. Determines injury to distal syndesmosis/ interosseous membrane
. Stabilize distal tibia, ankle dorsiflexed
. Side to side translation force introduced
. Pos. Is pain
. Indicates high ankle sprain
Kleiger/external rotation test
. Determines injury to interosseus membrane
. Patient seated w/ leg over table w/ knee at 90 degrees
. Fold foot at 90 degrees dorsiflexion
. Passive lat. rotation stress applied to foot and ankle
. Pain over ant. Or post. Talofibular ligaments w/ external rotation indicates syndesmosis Sprain
