Q

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

A

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.
