Quadrilaterals (tibia and femur) lengthening x-legs? non-fitbone patients.

Edit Post

Can someone tell me or link me to how quad LL causes xlegs?

That's why we talk about femur LL or quadrilateral lengthening.

Yes, I know, but he said BOTH tibia and femur internals cause x-legs which is not true. I got confused.

Check this out, I found this video on youtube by Dr Rozbruch. It is very simple, easy to understand and may be useful for those who think they have knock knees due to LL.

This is the way to fix misalignments after LL. I have the same plate in my right tibia as I did correction 3 months before together with at shortening surgery.

But what we want to know is if internal femurs cause x legs in every patient or it can be avoided.
If you want to do another surgery to fix it is another topic, the thing is if you can avoid it on the first time and not go for extra surgeries which mean extra time, money and much pain. My tibia fixing was 10 times more painful than LL which was almost painless for me.

As far as I know femurs are mostly straight that's why you can use internals without much of a problem. Tibia got natural curvature which causes X leg but again, apparently according to Dr Lee that can be also minimalized with appropriate nail positioning.

Could you tell me how much does this correction surgery cost?

I am currently doing internal femurs with Dr Paley and have almost finished my lengthening phase. I have not experienced any x-legs at all.
