Pedorthics ALREADY PASSED
What does a Pedorthist do? - =Specialize in shoes, shoe modifications, ankle-foot orthoses and
prostheses
What are the foot's bases of support - =Calcaneus
1st metatarsal head
5th metatarsal head
Talocrucal joint - =Talus
Fibula
Tibia
Hind foot - =Talus and calcaneus
Midfoot - =Navicular, cuboid, cuneiforms
subtalar joint - =talus and calcaneus
Purpose or subtalar joint - =Maintains balance during weight bearing and allows the foot to
adjust on uneven terrain
Midtarsal joint is also known as the - =Transverse tarsal joint
What is the transverse tarsal joint/midtarsal joint composed of? - =Talonavicular and
calcaneocuboid
Tibialis anterior - =Dorsiflexes and inverts foot
Origin: lateral condyle and proximal lateral shaft of the tibia
Insertion: base of metatarsal one and medial cuneiform
,Gastrocnemius - =Plantar flexes foot
Origin: posterior surface of the lateral condolence
Insertion: posterior surface of calcaneus via achilles tendon
Soleus - =Plantar flexes foot
Origin: posterior head and upper third of fibula shaft and posterior to the medial head of the tibia
Insertion: posterior surface of the calcaneus via the Achilles tendon
Fibularis brevis - =Plantar flex and evert the foot
Origin:Lateral distal 2/3 of fibula
Insertion: base of 5th metatarsal
Extensor hallucis longus - =Extends great toe
Origin: anterior surface of fibula
Insertion: dorsal surface of distal phalanx of digit 1
Tibialis posterior - =Plantar flexion and inversion of foot and adduction
Origin: interosseous membrane; posterior superior tibia, distal 2/3 of fibula
Insertion: navicular tuberosity, all cuneiforms, metatarsals 2-4, and cuboid
Anterior tibiotalar ligament - =Connect tibia and talus anteriorly; part of the deep deltoid
ligament
Posterior tibiotalar ligament - =Connects tibia and talus posteriorly; part of the deep deltoid
ligament
Deep deltoid ligament - =extends the function of the medial malleolus, prevents lateral
displacement of talus & prevents external rotation of the talus
, Made up of the anterior and posterior tibiotalar ligaments
Tibionavicular ligament - =Connects the tibia to the navicular; part of the superficial deltoid
ligament
Tibiocalcaneal ligament - =Connects the tibia and the calcaneous; part of the superficial deltoid
ligament
Superficial tibiotalar ligament - =Connects the tibia to the talus superficially; makes up the
superficial deltoid ligament
Superficial deltoid ligament - =Made up by the tibionavicular ligament, tibiocalcaneal ligament,
and superficial tibiotalar ligament
Resists eversion of the hindfoot
Plantar calcaneonavicular ligament - =Spring ligament***; comments the calcaneus to the
navicular on the plantar surface of the foot
Medial longitudinal arch ranges from - =Calcaneus to 1st met head
The medial longitudinal arch is supported by these ligaments - =Plantar aponeurosis
Short and long plantar ligaments
Spring ligament/ plantar calcaneonavicular ligament
The medial longitudinal arch is supported by these muscles - =Tibialis anterior
Tibialis posterior
Flexor hallucis longus
Gastrocnemius
Soleus
