Quote from: E Z on March 13, 2021, 07:11:40 AMWhat health issues could this cause? As a stryde patient, I’m extremely worried right now. My nails are still in and it has been almost 1.5 years post-op
Why don't you get the nail removed since it's been so long? Better to be safe than sorry...

And 0 internal nail has to be safer than 1.

Looks like I wasn't far off. 
Except I would have never guessed their primary solution is to coat or encapsulate the device. That's creative.
To summarize, the main point is at 14:30. He says of 122 implants that they followed up in a year on:
- 36% of the bones were totally normal
- 64% total of the bones had abnormal changes
Of those 64% with abnormal bone reactions, it was broken down into:
- 40% had extra bone thickening (hypertrophy)
- 3% bone breakdown (lysis).
- 21% had combination of hypertrophy and lysis.
The issue seems to develop at 6-12 months once the distraction is done. There have been no fractures so far from lysis, but that would be the main threat. He didn't talk about what you'd need to do if you got bad lysis (as none have had it so far that bad), but I presume you might need a permanent nail or grafting if it fractured and wouldn't thicken back up.
Then at ~51 min he talks about two possible solutions NuVasive is working on:
- Coat the junction in polyethylene (plastic)
- Add a sleeve over it to seal it the junction
He guesses if they try to fix the problem (rather than just re-release it) it will most likely happen by 10 months from now and maybe longer.

Precise-2 seems to be safe, so why not have just one frame (which is safer and easier than two) and stil be fully able to move around independently? Am I missing something here?

No I believe this is a bs method.
No reason to do intelnals on one leg and lon on the other. You have the disadvantages of both methods and no advantage compared to any of these methods on its own.
For tibias fully extrernals is the safest and most used way.
If you can't stand bulky frames and you have the money, do fully internals.
If you don't have enough money and want something in the middle, do lon with monorails.
Simple as that.
