Talocrural Joint
The number of DoF available at the talocrural joint
What is one?
The term used to describe the distal articulation between the tibia and fibula
What is syndesmosis?
This ligament runs from the neck of the talus to the neck of the of the calcaneus and is a strong stabilizer of the STJ
What is the cervical ligament?
The convex articulation of the posterior surface of the STJ
What is the calcaneus?
These are the three primary arches of the foot
What are the medial longitudinal arch, lateral longitudinal arch, and transverse arch?
The anterior drawer special test is used to evaluate the integrity of this ligament
What is the anterior talofibular ligament?
The type of injury associated with an injury to the distal tibiofibular joint
What is a high ankle sprain?
A lateral glide of the calcaneus would be performed to increase ROM in this direction
What is inversion?
The relative movement of the TTJ during early phase and late phase STJ pronation
What is supination --> pronation?
This pathology is associated with a collapsed, or lack of, medial longitudinal arch and perhaps a "flat foot"
What is pes planus?
This type of glide is performed to increase ankle dorsiflexion
What is a posterior talar glide?
The common MOI for a syndesmosis sprain is a combination of these two movements
These two muscles are the primary inverters of the foot
What are the tibialis anterior and tibialis posterior?
During a "pronation twist," these two rays of the foot plantarflex in order to maintain contact with the ground
What are the 1st and 2nd rays?
Describe the procedure of the Windlass test
(Pt stands on stool w/ toes hanging off, PT extends great toe at proximal phalanx, positive test = pain)
The CONVEX surface of the talocrural joint
What is the superior talus?
These three structures are the main stabilizers of the distal tibiofibular joints
What are the anterior tibiofibular ligament, posterior tibiofibular ligament, and interosseous membrane?
To perform a MMT of the fibularis brevis, resistance is placed on this distal segment of the foot
What is the fifth metatarsal?
This type of tibiofibular rotation is associated with weight bearing pronation
What is lateral / external rotation?
(Many)
The CONCAVE surface of the talocrural joint
What is the tibial plafond?
This type of glide at the distal tibiofibular joint is performed to increase ankle dorsiflexion
What is posterior glide?
These four muscles are innervated by the medial plantar nerve
What are the first lumbrical, abductor hallucis, flexor digitorum brevis and flexor hallucis brevis?
These are the three components of WB pronation
What are calcaneal eversion, talar plantarflexion, and talar adduction?
This is the muscle that plays the largest role in maintaining the MLA
What is the posterior tibialis?
