Joints & Ligaments of the Foot, Ankle & Leg Flashcards
A joint where the head of the fibula articulates with the lateral condyle of the tibia. There is a flat oval/circular facet on the fibular head which articulates with a similar facet on the tibia.
Proximal Tibiofibular Joint
What type of joint is the proximal tibiofibular joint classified as?
Synovial Plane Joint
With dorsiflexion, there is limited ________ and _________ glide at the proximal tibiofibular joint.
Superior
Posterior
With plantarflexion, there is limited ________ and ________ glide at the proximal tibiofibular joint.
Inferior
Anterior
A ligament that attaches between the anterior proximal tibia and the anterior proximal fibula.
Anterior Ligament of the Fibular Head
A ligament that attaches between the posterior proximal tibia and the posterior proximal fibula.
Posterior Ligament of the Fibular Head
A joint where the distal end of the fibula articulates with the distal end of the tibia.
Distal Tibiofibular Joint
What type of joint is the distal tibiofibular joint classified as?
Fibrous Joint
Strong connective tissue between the tibia and the fibula which thickens at the distal end (helps stabilize bones for walking).
Interosseous Membrane
A ligament that attaches between the anterior distal tibia and the anterior distal fibula.
Anterior Tibiofibular Ligament
A ligament that attaches between the posterior distal tibia and the posterior distal fibula.
Posterior Tibiofibular Ligament
A joint where the distal ends of the tibia and fibula articulate with the trochlea (dome) of the talus. Commonly referred to as the ankle joint.
Talocrural Joint
What type of joint is the talocrural joint classified as?
Synovial Hinge Joint
What 2 movements are available at the talocrural joint?
1) Dorsiflexion
2) Plantarflexion
Which 4 ligaments make up the deltoid ligament?
1) Anterior Tibiotalar
2) Tibionavicular
3) Tibiocalcaneal
4) Posterior Tibiotalar
A ligament that attaches between the medial malleolus and the tarsal bones of the medial foot. It checks eversion of the ankle and is a very strong ligament that can lead to avulsion fractures.
Deltoid Ligament
When a small chunk of bone is pulled away by a tendon/ligament.
Avulsion Fracture
A ligament that attaches between the lateral malleolus and the neck of the talus. It checks inversion of the ankle, especially in plantar flexion. It is palpated through the sinus tarsi.
Anterior Talofibular Ligament (ATFL)
Which ligament is the most commonly injured in the ankle, accounting for 95% of ankle sprains?
Anterior Talofibular Ligament (ATFL)
A ligament that attaches between the lateral malleolus and the lateral calcaneus. It checks inversion when the ankle is in neutral.
Calcaneofibular Ligament
A bursa located between the Achilles tendon and the overlying skin.
Subcutaneous Calcaneal (aka. Retrocalcaneal)
A bursa located between the Achilles tendon and the calcaneus.
Subtendinous Calcaneal
A joint where the inferior aspect of the talus articulates with the superior calcaneus.
Subtalar Joint
What type of joint is the subtalar joint classified as?
Synovial Plane Joint
What 2 movements are available at the subtalar joint?
1) Inversion
2) Eversion
A joint involving the articulation between the talus, the calcaneus, and the navicular. The spring ligament and the sustentaculum tali are also involved.
Talocalcaneonavicular Joint
What type of joint is the talocalcaneonavicular classified as?
Synovial Ball & Socket Joint
Which 2 movements are increased at the talocalcaneonavicular joint?
1) Inversion
2) Eversion
A ligament that attaches between the sustentaculum tali and the posteroinferior surface of the navicular.
Plantar Calcaneonavicular Ligament (aka. Spring Ligament)
Which ligament helps to maintain the medial longitudinal arch by supporting the head of the talus?
Plantar Calcaneonavicular Ligament (aka. Spring Ligament)
Term referring to flat feet.
Pes Planus
Term referring to high arch.
Pes Cavus
