osteology of leg

Question 1

what is attached in anterior intercondylar fossa

Answer 1

anterior horn of medial and lateral meniscus, anterior cruciate ligament

Question 2

posterior intercondylar fossa attachment

Answer 2

posterior horn of lateral meniscus, posterior horn of medial meniscus, posterior cruciate ligament

Question 3

what is the difference between the shaft vs distal end of tibia and how are the surfaces connected from shaft to distal end?

Answer 3

shaft has 3:

borders: anterior, medial lateral
surfaces: posterior, medial, lateral

Distal end has 5 surfaces: anterior, posterior, medial, lateral and inferior

anterior surface of distal tibia is continuous with lateral

posterior surface of distal tibia is continous with posterior surface of shaft superiorly, inferiorly it is continous with medial malleolus.

Question 4

Answer 4

tibial tuberosity to the anterior border of medial malleolus

crural fascia attaches to ant border

Question 5

what attaches to the the medial border of tibia

Answer 5

tibial collateral ligament, popliteus, soleus , FDL

Question 6

what attaches to the medial superior surface of tibia?

Answer 6

sartorius, gracilis, semitendinosus= pes anscerinus

tibial collateral ligament

Question 7

what is located on the lateral surface of the tibia?

Answer 7

ONE muscle attachment: TA- upper 2/3 
distal end (med-lateral): tibialis anterior, extensor hallucis longus,EDL , peroneus tertius

Question 8

what is the direction of the soleal line on Tibia? what is the second line on the posterior surface? what attaches medial and lateral to it

Answer 8

superolateral to inferomedial

vertical line

• medial: FDL
• lateral: TP

Question 9

where does the nutrient branch branch from for the tibia? how is the nutrient forament directed?

Answer 9

Question 26

what demarcations are located in the posterior surface of tibia

Answer 26

soleal line and vertical line

Question 27

where does the nutrient foramen lie in the tibia

Answer 27
