Ankle Flashcards
hindfoot
talus and calcaneus
Midfoot
Navicular, cuneiforms, cuboid
Forefoot
Metatarsals and phalanges
Talus
Articular cartilage covers
> 1/2 of its surface
Talus articulates with
tibia, calcaneus, fibula, and navicular
Talus consists of
head, neck, and trochlea
Calcaneal tuberosity attachment of the
achilles tendon
Plantar surface of calcaneal tuberosity has lateral and medial processes, attahcments for many
intrinsic ms and the deep plantar fascia of the foot
Calcaneus articulates with
cuboid and talus
- Navicular
- Proximal (concave) surface accepts the head of the talus at the
talonavicular
Navicular
Distal surface contains 3flat facets that articulate with the
3 cuneiforms
Navicular tuberosity attachment for
Tibialis Posterior
Cuneiforms contribute to the
transverse arch of the foot
Cuboid
Distally articulates with the bases of
4th and 5th metatarsals
Cuboid proximally articulates with
calcaneus
Cuboid medially articulates with
lateral cuneiform and navicular
Cuboid
Has a groove on plantar surface for the
fibularis longus tendon
Most mobile metatarsal
1st
Recessed metatarsal
2nd
Injuries at MTP joint include
bunions
Metatarsalgia
Inferior side of 1st metatarsal has
lateral and medial sesamoid bones
Fibularis brevis attaches to
styloid process of 5th metatarsal
Tibialis posterior attaches to
tuberosity of navicular, cuneiform, cuboid, and bases of 2nd, 3rd, and 4th metatarsals
Talocalcaneal joint (STJ)
Designed for
rotation, inversion, eversion
Talonavicular and calcaneocuboid joints (transverse tarsal)
talus, calcaneus, navicular, cuboid, cuneiforms
