Proximal tibiofibular joint (H) classification
Non-axial plane synovial joint
Ligaments of fibular HD
Ant/post bands
Proximal Tibiofibular joint CPP
Full dorsiflexion
Proximal tibiofibular joint Capsular Pattern
Pain on stress
Proximal tibiofibular joint typical dislocation
Rare: typically superior dislocation of fibular HD
Intermediate tibiofibular joint classification
Functional: amphiarthroidal (Ltd mobility)
Structural: Fibrous syndesmosis
Intermediate tibiofibular joint ligaments
Interosseus membrane
Prox/distal hiatus for arteries to pass through
Distal tibiofibular joint classification
Functional: ampiarthroidal (Ltd mobility)
Structural: fibrous syndesmosis
Distal tibiofibular joint ligaments and movement
Lig: Ant/post tibfib lig
mvmnt: small amounts of joint separation (1-2mm) w full dorsiflexion
Strongest of the ankle ligaments
Interosseus ligament
Interosseous ligament kinematics
Class 2 lever
Small motions at the lateral malleolus result in large motions in proximal tib/fib joint
Distal tibiofibular joint CPP
Full dorsiflexion
Distal tibiofibular joint capsular pattern
Pain on stress
Distal tibiofibular joint typical dislocation
High distraction force in the distal joint may lead to dislocation of fibula
With ________, the fibula abducts away from the tibia and fibula rotates ________ at distal end
Dorsiflexion, medially
With ___________, the fibula adducts toward the tibia and rotates ______ at the distal end
Plantarflexion, Laterally
Ankle mortise is made up of..
Medial malleolar and inf. articular facets of tibia
Lateral malleolar articular facet of fibula
Deep fibres of post. tibfib lig. (dist. to TF joint)
Talocrural joint classification
Uniaxial hinge synovial
The medial malleolus is slightly _____/______ compared to the lat. malleolus
Anterior/superior thus not a true medial-lateral axis
Both the knee and ankle move upon _____ axis
Oblique
In open chain, during dorsiflexion slight _______ must occur at the subtalar joint
Eversion
During open chain dorsiflexion of the talocrural joint the tib/fib rotate _______ and slides _______
Medially, superiorly
Plantarflexion at TC joint open chain
Slight inversion must occur at the subtalar joint
Occurs due to oblique axis
Plantarflexion at TC joint open chain the tib/fib rotate _____ and fibula adducts and slides _______
Laterally, inferiorly
