Joints of the Foot Flashcards
Name the two arches of the foot
- Transverse arch
2. Longitudinal arch
What are the functions of the arches in the foot
- Distribute weight
- Act as shock absorbers
- Act as spring boards
Which side of the foot has a more pronounced longitudinal larch
The medial side
What supports the transverse arch
- Tibialis posterior tendon
- Peroneus longus tendon
- Adductor hallucis muscle
- Deep transverse metatarsal ligament
What bones form the lateral side of the longitudinal arch
- Calcaneus
- Cuboid
- Metatarsals 4 and 5
What bones form the medial side of the longitudinal arch
- Calcaneus
- Talus
- Navicular
- Cuneiforms (x3)
- Metatarsals 1-3
What structures provide dynamic support of the longitudinal arch
- Intrisnic muscles of the foot
- Flexor hallucis longus tendon
- Flexor digitorum longus tendon
What structures provide passive support of the longitudinal arch
- Plantar calcaneonavicular (spring) ligament
- Short plantar (calcaneocuboid) ligament
- Long plantar ligament
- Plantar aponeurosis
How many different joints are within the foot
8
Name the different joints of the foot
- Subtalar
- Talonavicular
- Calcaneocuboid
- Cuneonavicular
- Tarsometatarsal
- Intermetatarsal
- Metatarsophalangeal
- Interphalangeal
What joints form the transverse tarsal joint
Talonavicular and calcaneocuboid joints
What type of joint is the subtalar joint
Plane synovial
Describe the arrangement of the subtalar joint
Talus is slightly concave posterior to the calcaneal articular surface; calcaneus is slightly convex posterior to the articular facet
What ligaments support the subtalar joint
Medial, lateral, interosseous and posterior talocalcaneal
Name the different sections of the transverse tarsal joint, and the type of joint
- Talocalcaneal = plane synovial
- Talonavicular = ball and socket
- Calcaneocuboid = plane synovial
