second longest and second strongest bone
tibia
male v female tibia
male is nearly vertical
female - distal end more medial compared to proximal end
inferior surface of tibia
tibial plafond
superior surface of tibia
tibial plateau
shape of the tibial plateau
oval
wider side tos ide
larger condyle on tibia
medial condyle
the roughened medial surface of medial condyle of tibia is an attachment site for…
tibial (medial) collateral ligament
three structures in non-articular intercondylar ridge of tibia
- anterior intercondylar fossa
- intercodnylar eminence
- posterior intercondylar fossa
what 3 attachments are at the anteriro intercondylar fossa?
- anterior horn of medial meniscus
- anterior cruciate ligament
- anteriro horn of lateral meniscus
where are the medial and lateral intercondylar tubercles located?
on intercondylar eminence between two intercondylar fossa
spine/ridge located b/w two intercondylar fossa
itnercondylar eminence
what 3 attachments are there to the posterior intercondylar fossa
- posterior horn of lateral meniscus

inferior
what attaches at tibial tuberosity
patellar ligament
the patellar ligament is a continuation of ..
quadratus femoris tendon
posterolateral depression on lateral tibial condyle
fibular facet
* oval shaepd
what are the borders of shaft of tibia?
anterior (shin)
medial
lateral
anterior border of tibia
tibial tuberosity to the medial malleolus
attachments to anterior border of tibia
crural fascia (Deep fascia of leg)
medial border of tibia
medial condyle to medial malleolus
4 attachments to medial border of tibia
- medial collateral ligament
- popliteus
- soleus
- flexor digitorum longus
anterior and medial borders of tibia corkscrew medially so at the medial malleolus …
anterior border becomes anterior border of malleolus
just as leg rotates medially in development
lateral border of tibial shaft aka
interosseous crest
lateral border of tibial shaft
extends from articular facet from fibula and divides to form tow ridges inferiorly (anterior and posterior borders of fibular notch)
what attaches to the anterior and posterior borders of the fibular notch?
posterior inferior tibiofibular ligament
what are the surfaces of the tibial shaft?
posterior
medial
lateral
between the anterior and medial borders of tibia

medial (superior protion)
what attach on the medial surface of the tibia superiorly
pes anserinus and tibial collateral ligamnet
attachment at roughened area superior protion, medial surface of tibia
tibial/medial collateral ligament
what attaches along inferior medial surface of tibial shaft
crural fascia
what is the only muscular attachment to lateral surface of tibia?
tibialis anterior
- upper 1/2 to 2/3 grooved by m origin
what 4 tendons cover the distal portion of lateral surface of tibia?
(medial to lateral)

describe the soleal line
- oblique ridge extending superolateral to inferomedial on posterior surface
- partial origin of soleus m
describe the vertical line
- extends inferiorly from soleal line on posterior surface of tibia
