Let's talk about LON femur
« on: June 04, 2024, 07:52:48 PM »

Now, apart from higher chance of getting bone infection, what are the other disadvantages of this method on femurs that might result in bad outcomes disregarding ugly scars it leaves which is not an issue and can be fixed later if needed.

Assuming one does no more than 7 cm, can he recover his ROM and mobility fully after a year or two post surgery?

There are many users here who did LON femur, some of them did more than 7 cm and according to them, they are fine now (Meck comes to my mind who did more than 9 cm with LON femur).

Assuming one has to wait for many years in order to afford PRECICE nails, is it justifiable in that case to go with LON femur in order to become taller significantly earlier?

Poor man's double LL option:

Do LON femur for 6.5 cm in order to remain in safe zone and after 6 months post surgery and adequate bone formation, go with pure external tibia for 5.2 cm. After about 10 months post tibia surgery, which means 16 months post femur surgery, you remove the nails from femurs and external frames from tibia in one surgery and stand at 11.5 cm taller with perfect interlimb proportions and biomechanics.

so ur going to put a nail in ur femurs and not in your tibias. with femur monorail u will do 3 surgeries and then your 2 surgeries with tibia skipping the frame removable just having it on for 6 months. and then ur frame removal. u will be in ur home for a long time for recovery and duckbutt if u go more than 6.5 cm.

What about misalignment? Why is there such a stance on the forum that LON femur causes misalignment but PRECICE 2 doesn't. I understand that huge amounts of lengthening will most certainly bend the nails inside but what about 5 cm distraction? In such a conservative amount, is the chance and severity of misalignment less compared with, let's say, 8 cm or more distraction?

I know that the nails used in LON method are not full weight bearing and it's as fragile as PRECICE 2 nails when it comes to walking without assistance (i.e. it might bend or break if the bone bridge is not enough). What about if one limits his weight bearing activities the same way PRECICE 2 patients limit in order to avoid nail bending? Will it lower the chance of nail bending, thus misalignment?

Keep in mind that I'm interested in only 5 or 5.5 cm LON femur lengthening and it's complication rates, not 9 or 10 cm which is another story and most certainly causes nail bending and misalignment.

Based what I know so far from this forum, even boby builder, loyal recommender of external for tibia, would strongly discourage LON femur.

For the misalignment part, can someone share how would that work in favour, if at all, for someone who has bow legs/knock knees?

Thats true. Also, no respectable doctor in the world performs lon femurs.
If you have a low budget the only way is external tibias. If you already did it and want femurs too, either you get enough money for an internal nail or you live with the height you already have. No other option.

Sorry I am new here, what's wrong with LON femurs? What if you have bowlegs, isn't thats how you fix it on femurs?
