Comment on “Tf???”
Murse@slrpnk.net 5 hours agoTo be clear, othopedics is not my area of expertise, so grain of salt, but to my understanding, it’s basically the radius bone, but of the leg. Aim your toes forward in the normal anatomical position; now rotate your entire foot to the left or right. That’s your fibula working. Without it, very limited rotation; but otherwise you can still walk and function mostly normally, just a bit impaired.
I have no idea how ‘chunk missing in the middle’ plays into that. Guessing you’d still have some rotation, but without a secure anchor point, it wouldn’t be great.

Eh… I do specialize in orthopedics and rehabilitation. You can still do all these things without a fully functional fibula, just to a reduced degree. The fibula only contributes to a few degrees of range of motion in the lower limb, we are talking about millimeters. It can be noticeable given enough time or a high enough level of vigorous activity. Most people would live a fairly active lifestyle without noticing this kind of damage to the fibula.

No shit? I would have guessed at least like 15 degrees of rotation. I think I took the radius comparison a bit too literal.

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.

So you won’t notice it unless you’re a ballerina or something?
