Orthopedic Structures Flashcards
attachment of plantar fascia
calcaneal tuberosity
uppermost part is the trochlea
talus
articulates the 3 cuniforms; anterior to talus
navicular
calcaneous, navicular, talus, 1st cuneiform, 1st metatarsal’ spring ligament, deltoid, plantar fascia
medial-longitudinal arch
calcaneous, cuboid, 5th metatarsal; short planar, long plantar, PF, peroneus longus
lateral longitudinal arch
metatarsal heads
anterior metatarsal arch
across transverse tarsal bones; short plantar lig and peroneal longus, tib posterior
transverse arch
pronation and supination occur at what joint
subtalar
flexion of distal phalanges 2-5
flexor dig longus
flexion of middle phalanges 2-5
flexor dig brevis
flexion of proximal phalanges
lumbricales
extension of middle phalanges
abductor hallucis,
extension of distal phalanges
lumbricales, ext digitorum longus, extensor hallicus longus
occurs in young, physically active adults
apophysitis of calcaneus (severs disease)
causes include pronation and trauma; athlete complains of mid-foot sprain with pain on dorsum of foot and.or over anterior/lateral ankle after an inversion mechanism; referred pain to heel
cuboid subluxation
ankle is PF with rearfoot locked, sudden forceful hyper-PF of forefoot results in dorsal displacement of proximal end of metatarsals
Tarsometatarsal fracture/dislocation
most common acute fracture is fx to the diaphysis at the base of the 5th metatarsal
jones
pain under 2nd or 3rd metatarsal heads; heavy callus forms in area od pain; causes include inflexibility of gastro/soleus complex
metatarsalgia
