Unit 2_The Foot/Ankle Flashcards
What is a hinge joint (uniaxial) that allows flexion/plantar flexion and extension/dorsiflexion?
Ankle (Talocrural)
What’s another name for the ankle joint?
Talocrural Joint
What is a joint of the ankle that includes articulation of the talus and calcaneus and allows inversion (sole turns in) and eversion (sole turns out)?
Subtalar Joint
What ligaments are also known as the Deltoid Ligament (medial collateral ligaments) and make up the medial side of the ankle? These ligaments help prevent an eversion sprain.
Anterior Tibiotalar Ligament
Tibionavicular Ligament
Tibiocalcaneal Ligament
Posterior Tibiotalar Ligament
What motion stresses the medial side of the ankle?
Eversion
What ligaments are known as the Lateral Collateral Ligaments of the ankle and are surrounded by the superior fibular retinaculum and inferior fibular retinaculum?
Anterior Talofibular Ligament (ATFL)
Calcaneofibular Ligament
Posterior Talofibular Ligament (PTFL)
What Lateral Collateral Ligament of the ankle is most often sprained/injured?
Anterior Talofibular Ligament (ATFL)
How do you assess the mobility of the ankle?
Anterior Drawer of the Ankle Test
Stabilize the tibula and fibula and provide an anterior glide. Looking for excess translation comparatively side-by-side
What are coverings of the anterior leg and dorsum of the foot to hold the tendons in place?
Superior Extensor Retinaculum
Inferior Extensor Retinaculum (Crural Cruciate Ligament)
What are coverings of the posterolateral ankle to hold tendons of fibularis longus and brevis mm in place?
Peroneal Tunnel
- Superior Fibular Retinaculum
- Inferior Fibular Retinaculum
What are coverings of the posterior compartment to hold the Tibialis posterior tendon, Flexor digitorum longus tendon, Posterior tibial artery and vein, Tibial nerve, and Flexor hallucis longus tendon of the leg found on the ankle?
Flexor Retinaculum
Tarsal Tunnel
What are the 7 tarsal bones of the foot?
Cuboid
Talus
Calcaneus
Navicular
3 Cuneiforms (medial, intermediate, lateral)

What are the bones of the foot?
Tarsal bones (proximal), Metatarsal bones, Phalanges of the foot
What are the joints of the foot?
Intertarsal Joints
Tarsometatarsal Joints
Metatarsophalangeal Joints
Interphalangeal Joints
What joints of the foot are gliding joints (for flexibility) and are found between the tarsal bones?
Intermetatarsal Joints
What joints of the foot are gliding joints and are found between the distal row of tarsal bones and the base of the metatarsals?
Tarsometatarsal Joints
What joints of the foot are condyloid joints and allow for dorsiflexion/plantar flexion, abduction/adduction?
Metatarsophalangeal Joints
What joints of the foot are hinge joints and allow for dorsiflexion/plantar flexion?
Interphalangeal Joints
What are the arches of the foot?
Medial and Lateral Arches
What extrinsic muscle tendons support the arch of the foot?
Tendon of Tibialis Anterior
Tendon of Tibialis Posterior
Flexor Hallucis Longus
What muscle supports elevating the arch?
Fibularis Longus
What bony prominence on the upper portion of the calcaneus allows for the Flexor Hallucis Longus to assist with elevation of the calcaneus?
Sustenaculum Tali
What structures support the arches of the foot?
Dynamic support provided by ligaments, bones, intrinsic foot muscles, and tendons of extrinsic muscles
What is a fallen arch or “flat foot” that can result from an injury, polyneuropothy, and/or someone may be born with it known as?
Pes Planus
