LEA Tibia Fibula Foot Intro Flashcards
where is the fibula palpable
the head and lateral malleolus
where does the fibula articulate
with the talus and tibia
1st ossification center of the tibia
shaft; 7th- 8th fetal week
2nd ossification center of proximal epiphysis
appears around birth and fuses about 18 years of age
2nd ossification center of the distal epiphysis
appears around age 1 and fuses about 16 years of age
2nd ossification centers of the medial malleolus
- appears between 8-13s years of age
- not always a separate ossification center
- fuses 15 in females, 17 in males
2nd ossification centers: tibial tuberosity
- appears around ages 10-12
- fuses between 14-18
fibula 1st ossification center
shaft about 8th fetal week
distal fibula 2nd ossification center
appears 1st year of life and
fuses around 15-17 years age
proximal fibula 2nd ossification
appears during the 3rd year fuses around 17-19 years of age
2nd ossification fuse in what order
in the order of appearance, different pattern of fusion than other long bones
calcaneofibular ligament attaches
summit of the lateral malleolus
can be the site of avulsion fractures in the distal fibula
the summit of lateral malleolus
the medial triangular surface of the distal fibula is a __ joint
syndesmotic
the distal tibiofibular joint is formed from
the articulation of the medial triangular surface of fibula and the fibular notch of tibia
the triangular facet of medial surface of distal fibula articulates with
the talus
transverse tibfib and posterior talofibular attach to
lateral malleolar fossa
fibularis longus and brevis tendons pass
lateral malleolar sulcus
the lateral malleolus is more ___ than medial malleolus
distal and posterior
the lateral malleolus resists
eversion
aponeurosis attachment on the fibula
crista medialis
the interosseous membrane attaches where on fibula
interossesous medial border
Separates anterior and lateral compartments
anterior intermuscular septum
the anterior shaft of the fibula splits distally to
enclose a lateral triangular area above lateral malleolus that is subcutaneous and palpable
superior (proximal) tibiofibular joint is a __ joint
gliding (planar) synovial and diarthrotic
superior (proximal) tibiofibular joint is located
between the head of the fibula and the lateral tibial condyle
ligaments of the superior (proximal) tibiofibular joint
anterior and posterior proximal tibiofibular ligaments
superior (proximal) tibiofibular joint blood supply
tibial recurrent arteries and
inferior lateral genicular arteries
superior (proximal) tibiofibular joint innervation
- common fibular
2. nerve to popliteus
gliding movements of the superior (proximal) tibiofibular joint occur when
the ankle joint moves in dorsiflexion and plantar flexion
the interosseous membrane attaches
interosseous borders of the tibia and fibula.
the interosseous membrane fibers are arranged
angels inferiolaterally
the distal (inferior) tibiofibular joint
between fibular notch of tibia and medial triangular area of fibula
distal (inferior) tibiofibular joint is a __ joint
syndesmosis, amphiarthrosis
ligaments of the distal (inferior) tibiofibular joint resist
prevent the separation of tibia and fibula and alar wedging
the four distal (inferior) tibiofibular joint ligaments
1 Distal anterior tibiofibular ligament
2 Interosseous tibiofibular ligament
3 Distal posterior tibiofibular ligament
4 Inferior transverse tibiofibular ligament
Talocrural joint
between tibial plafond,
lateral malleolar articular facet,
medial malleolar articular facet
and talus
Midtarsal Joint (Chopart’s joint, transverse tarsal joint):
between rearfoot and midfoot
Lisfranc’s joint (tarsometatarsal joint):
between the midfoot and forefoot
