1. Tibia & Fibula Flashcards
overall fxn of tibia
directly articulates w/ femur
weight is transferred thru condyles
overall fxn of fibula
serves as attachment site for muscles
not much weight/if at all is transferred
name the structure on the tibial plateau:
in green
what attaches here?
tibial tuberosity;
patellar ligament/tendon, & quadriceps tendon both attach here
name the structure on the tibial plateau:
in BLUE
intercondylar eminence/ prominences
*aka “spines” or “processes”
- name the structure(s) on the tibial plateau:
in yellow
- What attaches here?
anterior intercondylar area
ACL attaches here
- name the structure(s) on the tibial plateau:
in purple
- What attaches here?
posterior intercondylar area
PCL attaches
which color is the MEDIAL articular surface?
how do you know?
pink
•medial condyle is elongated, larger, less C-shaped,
whereas lateral is more C-shaped
which bone is this?
identify the surfaces
tibia
- lateral surface - more concave
- medial surface - less concave
- posterior surface
identify MEDIAL surface?
what attaches here?
2.
pes anserinas attaches here
on what surface is the nutrient foramen located?
what is it a branch of?
posterior surface (3)
nutrient artery is a branch of the posterior tibial artery (near it’s origin)
name the borders
- anterior border
- medial border
- lateral/interosseus border
name the muscular compartments located on the tibia
which surface does it correspond with?
(1) anterior compartment muscles (on lateral surface)
(3) posterior compartment muscles (on posterior surface)
describe the course of the anterior border of the tibia?
starts from TIBIAL TUBEROSITY proximally,
extends down anteriorly
forms anterior border of medial malleolus
describe origin and course of soleal line
starts below articulation of tibia and fibula
descends obliquely towards medial side, joining medial border
what inserts ABOVE soleal line?
what originates ON the soleal line?
popliteus inserts above soleal line (deep muscle of posterior compartment)
soleus originates ON the soleal line
the vertical line of tibia separates which 2 muscle attachments?
Tibialis posterior (laterally) and
Flexor digitorum longus (medially)
relationship of nutrient foramen and vertical line?
nutrient foramen is on posterior surface, LATERAL to the vertical line
where does the fibula attach distally?
what type of joint is this?
at the fibular notch
forms a syndesmosis
shape of articular facet on tibia for the talus?
comma shaped
from the lateral view, which COLLICULUS extends further distally?
the anterior colliculus
name the grooves, from medially –> laterally
on the posterior view of the tibia
- medial malleolus
- groove for TIBIALIS POSTERIOR
- groove for FLEXOR HALLUCIS LONGUS
- fibular notch
name the inferior surface of the tibia, which articulates w/ dome of the talus
the PLAFOND
of the plafond, which surface is longer?
(anterior/posterior)
Anterior is longer than posterior
