The radius moves a lot more than the fibula, which makes sense considering the need for moderate rigidity for weight bearing. The fibula only moves around a degree in internal and external rotation and less than a degree in the sagital tilting.
If you think about the rom in the ankle compared to the wrist it makes a bit more sense.
Yeah I wasn’t thinking ankle at all. And even here and now, I’m trying to rotate my own leg while keeping the ankle rigid, and… yea it doesn’t go very far. Never really appreciated just how large a role the ankle plays there.
No shit? I would have guessed at least like 15 degrees of rotation. I think I took the radius comparison a bit too literal.
