Foot & Ankle Flashcards
What 2 bones make up the lower leg
Tibia and fibular
What does the tibia form distally
Medial malleolus
What does the fibular distally form
Lateral malleolus
What bones does the ankle involve
Talus, distal tibia and the fibula
What bones does the foot involve
Tarsal, metatarsus and the digits
Function of the foot & ankle
Stability, support, absorb shock, balance
What 3 groups are the tarsal bones split into
Proximal, intermediate and distal
Name the 2 proximal tarsal bones
Talus and calcaneus
Name the only intermediate tarsal bone
Navicular
Name the 2 distal tarsal bones
Cuboid and cuneiforms
What does each metatarsal consist of
Head, shaft and base
What type of bone are the metatarsals
Sesamoid bones - articulate with head of metatarsals & embedded within tendons of flexor hallucis brevis
What 3 parts are there to the phalanges
Proximal, middle and distal
Each has a head, shaft and base
Name the membrane that spans the distance between the tibia and fibula shaft
Interosseous membrane
Name the joint that connects from the proximal head of the fibula to the inferno lateral surface of lateral condyle of the tibia
Superior tibio fibular joint
What is the ankle joint called
Talocural
State the degrees of movement for dorsiflextion and plantarflextion
Dorsiflextion (knee extended) = 20-30 degrees
Dorsiflextion (knee flexed) = 35 degrees
Plantarflextion = 50 degrees
Sub talar join range of motion
Inversion = 45-60 degrees
Eversion = 15-30 degrees
What type of joint is the mid tarsal joint
Synovial ball and socket joint
Where is the tarsometatarsal joint
Tarsal bones and the metatarsals
Where is the metatarsophalangeal joint
Between the metatarsals and the phalanges
Where’s the interphalangeal joint
Proximal interphalangeal joint (PIP)
Distal interphalangeal joint (DIP)
Name the 7 ligaments
Medial deltoid ligament
Lateral ligament = anterior, posterior talofibular & calcaneofibular
Plantar calcaneonavicular ligament
Bifurcate ligament
Short & long plantar ligament
Deep transverse metatarsal ligaments
