LON/LATN nail weight bearing? and walking

Edit Post

Android/Kilo or anybody else - my questions are i) is there is any time difference between LON and LATN in being able to walk with crutches and ii) I know LATN nail is thicker than LON nail but my question is - are these weight bearing or only partially weight bearing? I intend to use crutch after I complete lengthening and get the nail and do not intend to put full wight, but still want to know if it is weight bearing and how much can it (LATN/LON nail) be trusted to bear weight. Thanks.

I'm sure it depends on the patient's weight and healing rate, but this paper (LON vs Ilizarov) suggests partial weight bearing until full consolidation. A paper focused on LATN also mentions partial weight bearing.

You can refer to Dr. Donghoon's chart comparing LON, LATN, and PRECICE 1.0. It's a bit old, but should help in answering your question. Here's another page comparing LON and LATN.

Here's a pros and cons list (starting page 3) by Dr. Paley back in 2012, and LON/LATN has pros of weight bearing for transfers, meaning a few steps here and there.

TL;DR - partial weight bearing for both LON and LATN.

Thanks a lot Android. Much appreciated.

one question - the links you sent basically say that LATN patients walk (after nailing, limping walk, I don't mean normal walk) faster (I used to think so as well) but you mention that LON patients can walk faster, am a bit confused, can you advise. Thanks.

LATN, after lengthening you need a few weeks for correction using a hexapod. After that, nails are inserted and locked in second surgery when frames come off. So there's more pain involved on the second round. Luckily bone healing speeds up at this stage for LATN patients.

Benefit of LATN is outlined on page I linked to earlier:

And here's another comparison, again from link above:

TL;DR of above quote: compared to LON, LATN allows for stronger nails for stability, less mechanical resistance during lengthening, infections are less serious, and allows for deformity correction.

ok , thanks  a lot
