foot and ankle Flashcards
fibularis longus
O: head of the upper portion of fibula
I: by long tendon under foot to metatarsal I and medial cuneiform
fibularis brevis
O: distal portion of fibula shaft
I: by tendon running behind lateral malleolus to insert on proximal end of metatarsal V
tibialis anterior
O: lateral condyle and upper 2/3 of tibia; interosseous membrane
I: by tendon into interior surface of first cuneiform and metatarsal I
extensor digitorum longus
O: lateral condyle of tibial proxima 3/4 of fibula; interosseous membrane
I: tendon divides into four parts; inserts into middle and distal phalanges of toes II-V
fibularis tertius
O: distal anterior surface of fibula and interosseous membrane
I: tendon inserts on dorsum of metatarsal V
extensor hallucis longus
O: anteromedial shaft of fibula and interosseous membrane
I: tendon inserts on distal phalanx of great toe
gastrocnemius
O: medial and lateral heads from medial and lateral condyles of femur
I: calcaneus via calcaneal tendon
soleus
O: proximal portion of tibia and fibula; interosseous membrane
I: calcaneus via calcaneal tendon
popliteus
O: lateral condyle of femur and lateal meniscus
I: proximal tibia
tibialis posterior
O: superior portion of tibia and fibula and interosseous membrane
I: tenson passes obliquely behind medial malleolus and under arch of foot; inserts into several tarsals and metatarsals II-IV
flexor digitorum
O: posterior surface of tibia
I: distal phalanges of toes II-V
flexor hallicus longus
O: middle portion of fibula shaft; interosseous membrane
I: under foot to distal phalanx of great toe
