Ankle & Foot Flashcards
This joint isolates movement to purely plantar and dorsiflexion. It also transfers ground reaction forces to the knee
Tibiofibular joint
The talocrural joint’s axis of motion runs:
- medial to lateral
- superior to inferior
- anterior to posterior
Bones in the rear foot
Talus
Calcaneus
Bones in the mid foot
Navicular
Cuboid
3 Cuneiform
Bones in the fore foot
Tarsals
Metatarsals
Phalanges
Explain how tibial torsion is measured
- A line through the tibial plateaus
- A line through the medial and lateral maleoli
- Measure angle
- Bird’s eye view (from above)
The transverse tarsal joint (midtarsal joint) is made up of what two joints?
- Calcaneocuboid jt
2. Talonavicular jt
Inversion + PF + fore foot adduction is called:
Supination (of the foot)
Eversion + DF + fore foot abduction is called:
Pronation
A rigid foot is associated with ____ (Pronation, Supination)
Supination
A flexible (or mobile) foot is associated with ____ (Pronation, supination)
Pronation
Inversion/eversion occur primarily at what two joints of the foot?
- subtalar jt
- transverse tarsal jt
Abduction/adduction occur primarily at what two joints of the foot?
- subtalar jt
- transverse tarsal jt
The anterior compartment muscles of the leg perform ___ as one of their primary actions
Dorsiflexion
The ligaments of the ankle provide ___ (active, passive) stability
Passive
The triangle shaped ligament on the medial side of the ankle is known as:
Deltoid ligament
The arch supporting ligament from the calcaneus to the navicular bone is known as:
Spring ligament
Extension/dorsiflexion of metatarsophalangeal joint places traction on the plantar fascia and causes the arch to elevate. This is known as:
Windlass effect/mechanism
The windlass effect causes ___ of the calcaneus coupled with ___ of the tibia and fibula
Inversion, external rotation
The minimum functional range for the hallux limitus (the ability of the first proximal phalanx to extend on the metatarsal head)
55 degrees
Which two joints in the foot bear most of the load?
- Talonavicular
2. Cuneonavicular
The position with the least amount of joint surface contact/congruency and ligaments are lax is known as:
Open/loose packed position
Open packed position of the foot?
Plantar flexion
Closed packed position of the foot?
Dorsiflexion
2 phases of gait:
- Stance phase
2. Swing phase
The stance phase makes up __% of the gait cycle, while the swing phase makes up __%
62%, 38%
