Tibia

Question 1

Tibial plateau

Answer 1

proximal tibial surface on which the femur rests

Divided into two articular sections one for each femoral condyle

Question 2

Medial condyle

Answer 2

the medial part of the tibial plateau
its femoral articulation is oval with the long axis oriented anteroposteriorly
its lateral edge is straight

Question 3

Lateral condyle

Answer 3

the lateral part of the tibial plateau

its femoral articulation is smaller and rounder than the medial articulation

Question 4

Intercondylar eminence

Answer 4

the raised area on the proximal tibial surface between the articular facets

Question 5

Medial intercondylar tubercle

Answer 5

forms the medial part of the intercondylar eminence

Question 6

Lateral intercondylar tubercle

Answer 6

forms the lateral part of the intercondylar eminence

Question 7

Superior fibular articular facet

Answer 7

located on the posteroinferior edge of the lateral condyle

Question 8

Tibial tuberosity

Answer 8

the rugose area on the anterior surface of the proximal tibia
the superior part is smoothest and widest

Question 9

Tibial shaft

Answer 9

the fairly straight segment of the tibia between the expanded proximal and distal ends

Question 10

Soleal (popliteal) line

Answer 10

crosses the proximal half of the posterior tibial surface from superolateral to inferomedial

Question 11

nutrient foramen

Answer 11

inferolateral to the popliteal line

large foramen that exits the bone proximally

Question 12

Anterior surface (anterior crest)

Answer 12

of the shaft forms the anterior edge of the “shin”

Question 13

Medial surface

Answer 13

of the shaft forms the medial edge of the “shin” of the lower leg

Question 14

Interosseous surface

Answer 14

of the shaft is lateral, opposite the fibula

most concave of the three tibial surfaces

Question 15

Interosseous crest

Answer 15

the lateral crest of the shaft which faces the fibula

Question 16

Medial malleolus

Answer 16

the projection on the medial side of the distal tibia that forms the subcutaneous medial knob at the ankle
its lateral surface is articular for the talar body

Question 17

Fibular notch

Answer 17

the distolateral corner of the tibia

triangular nonarticular area

Question 18

Inferior fibular articular surface

Answer 18

a thin articular surface fro the fibula, which faces laterally at the base of the fibular notch

Question 19

Malleolar groove

Answer 19

on the posterior aspect of the medial malleolus

Question 20

Siding: intact

Answer 20

the tibial tuberosity is proximal and anterior

the medial malleolus is on the distal end and is medial

Question 21

Siding: proximal end

Answer 21

the tibial tuberosity is anterolateral, the fibular articulation is placed posterolaterally and the lateral femoral articular surface is smaller, rounder and set laterally
the intercondylar eminence is set posteriorly

Question 22

Siding: fragments of shaft

Answer 22

the entire shaft tapers distally and the interosseous crest is lateral and posterior
the medial surface is the widest and faces anteriorly
the nutrient foramen is posterior and exits proximally
the cortex is thickest at mid-shaft

Question 23

Siding: distal end

Answer 23

the malleolus is medial and its distal most projection is anterior
the fibular notch is lateral and the interosseous crest runs toward its anterior surface
the margin of the articular surface for the superior talus is grooved on the anterior surface but not the posterior surface
