Ligaments
This is the motion limited by a deltoid ligament limit and its location
What is eversion?
Medial side of ankle, inferior to malleolus
This phalange only has 1 interphalangeal joint
Hallux
There are two intrinsic muscles on the dorsal foot. What are they?
Extensor Digitorum Breves (extension of first 4 toes)
Dorsal Interossei (abduction of toes 2-4)
The plane of motion for inversion and eversion
Frontal plane about an anterior-posterior axis
the position of the foot when the talocural joint is the least stable
Full plantar flexion; also called loose packed
This is the ligament that is most commonly sprained in the ankle.
Anterior Talofibular
These are the nerves that most likely innervate the nerves that dorsiflex the foot
Deep Fibular Nerve
These extrensic muscle act as a direct agonist of the Tibialis Anterior
Fibularis brevis
Fibularis longus
This proximal joint allows for motion in the horizontal and frontal plane.
Subtalar joint
Inversion/Eversion
Abduction Adduction
These bones make up the malleolus
Distal ends of the tibia and fibula
These are the bones that are connected by the deltoid ligment.
Tibia > Navicular
Tibia> Calcaneal
Tibia>Talas
These bones make up the midfoot
Medial, Intermediate and lateral cuneiform
Cuboid
List the extrinsic muscles that plantar flex and invert the foot
Tibialis posterior
Flexor Digitorum Longus
Flexor hallucis longus
Achilles tendon (gastrocnemius, plantaris, soleus)
What are the kinematics of the ankle when walking? (Referring to the roll and slide)
Roll and slide are in the same direction
DF- anterior
PF - posterior
This describes gate cycle
Two successive heel contacts of the SAME leg while walking
List the 3 LCL ligaments.
Anterior Talofibular Ligament
Calcaneofibular ligament
Posterior Talofibular Ligmanet
These bones articulate to form the 5 tarsometatarsal joints.
Medial Cuneiform and 1st metatarsal
Intermediate cuneiform and 2nd metatarsal
lateral cunefiorm and the 3rd metatarsal
Cuboid and 4th metatarsal
cuboid and 5th metatarsal
This muscle has the ability to plantar flex the foot and flex the knee
Gastrocnemius
This joint allow for the purest form pronation and supination. Allowing three degrees of freedom
Transverse tarsal joint
A conditon that occurs when a person has an excessively fallen or dropped medial longitudinal arch
pes planus
This ligament limits excessive inversion of the
Lateral collateral ligament
Calcaneus and the proximal phalanges
In the talocural joint the concavity formed by the tibia and fibular is often referred to as ....
The mortise
This joint allows for 20 degrees of dorsiflexion and 60 degrees of plantar flexion
Talocrural Joint
Name the articulations between the subtalar, talocural, and the transverse tarsals
- talocural- Trochlea of the talus articulates with the concavity of the distal tibial and fibula
- Subtalar - three inferior facets of the talus match with the superior facets of the calcaneus
-Transverse tarsal - two articulations; one with the talonavicular joint and calcaneocuboid joint
