Clarifications about the Stryde recall

Obviously, being able to walk is better, but moving around with a walker is far better than a wheelchair.

I am interested in doing precice as well. How much did you lengthen, how much did you weight and when where you able to use crutches?

I would expect it's likely permanent. Once the bones heal that is just the way they are. Sometimes bones can remodel a bit after healing. Like if you fixate a bone with a slight misalignment and there is a jagged point sticking out at either end usually that will smooth over with time. But generally the way it heals is the way it remains.

If Paley is right, as long as you aren't showing obvious lysis or weak points that thickening will do you no harm. He says he believes this hypertrophic bone should be stronger than normal bone.

Definitely not permanent. Bones always remodel.

Remodeling is always going to happen. A hole from corrosion will be filled in. hypertrophy will go back to normal. Lysis will go back to normal.
Active corrosion from the nail is what causes this to occur. Once it is removed, remodeling happens

Email Paley if you don't believe me. Also emailed giotikas and he confirmed, removal causes this to eventually remodel and go away

If it's permanent, what's the point of removal then? You're already screwed for forever? Our bones are amazing. They remodel everything.

It will go back to normal. Bones are amazing.

Thanks guys. I've just had time to watch the whole thing there. I think at 25 mins Paley mentions that the thickening goes away after a couple of years, hope this is true.

What I don't understand is why the bone is thickening at the corrosion sites. I get why it would thicken at the screw sites due to adapting to stress load but I'm confused as to why it thickens in an area where there is no direct load placed on the bone. It seems like the bone is almost reacting to the rust in the same way a tissue would to inflammation caused by an infection or likes, I hope I'm completely wrong about this.

You're absolutely right. He even said it in the video. I recommend watching the whole video in detail. Paley specifically acknowledges this. He's not hiding anything, and he tells us that this corrosion is directly causing the bone adjacent to react. He concurs everything you said, in the video.

My experience was very similar to Purushrottam's.  I do recommend giving his diary a read.

My only worry is that, although Paley says the bones are thicker and stronger, it's the reason why they became thicker that worries me. If the hypertrophy occurred due to load bearing exercise or similar then in all probability the bone will be healthy, if it enlarges due to inflammation caused by corrosion then surely it's reasonable to assume there might be something wrong. I'm just curious if a sample of the bone tissue was examined at a cellular level would it be as healthy as normal bone?

Yes, it's not ideal obviously and they are going to find a solution to this to prevent corrosion from affecting the bone. It can and has burned holes through the bone so it's not a good thing and hopefully Nuvasive fixed this soon so people can do CLL!

Not ideal, little bit of an understatement If there was some clarification as to whether or not the thickened bone at the corrosion site is normal, healthy bone then I think it would put a lot of people's minds at ease. The only way they could test that though is by taking a sample and analyzing it.
