(Chapter 4) Footnote 39:

Hippocrates De locis in homine 26.6.48 describes the knee joint as “hingelike,” gigglumoeidh/j; so also the arm joint in De fracturis 2.16.22. Galen De ossibus ad tirones 2.735.13, In Hippocratis librum de fracturis commentarii 18b.349. A good example of a pivot joint is the articulatio radio-ulnaris proximalis. Vesalius re-uses this drawing of a hinge in chapter 15 to illustrate the movement of the atlas on the dens or odontoid process of the axis (second neck vertebra).
