STRYDE cannot withstand full weight bearing, according to NUVASIVE

Quote from: wanttaller on November 18, 2019, 03:08:16 PMHey, how much did you lenghten with Betz?
Because you said you were on crutches for almost a year.

9cm in the left femur, 10cm in the right femur (I had a 1cm discrepancy in the femurs.).
It took me 4 months to length then 5 months until I could get off crutches.
I felt strong enough to walk around 3 months post-lengthening, but Betz only gave me ok to get rid of the crutches at 5 months post-lengthening so I listened to him.

People weigh different amounts, and most of the body's mass is above the legs anyway.  So maybe "full weight bearing" isn't a claim anyone should make about a device alone.

I'm wondering if the NUVASIVE point of Stryde not being weight bearing is only for tibia (the .pdf I linked above is the instructions for a tibia surgery, not femur).

Do we have any diary here of people doing Tibia with Stryde and walking during lengthening?

No, I have the Nuvasive Stryde manual for femur and there's written exactly the same. Your confusion is due to the bs which has been spread all those years by Betz. No serious manufacturer will simply write his implant is fully weight bearing without any restrictions because he will be liable in case of problems.

Only Betz has the brazenness to state his nail is fully weight bearing but at the same time doesn't accept liability in case something happens. You were simply very lucky nothing happened to you in 2012.

Stryde is FDA approved. Betzbone has only CE marking. For CE marking the manufacturer only needs to pay a private consultant. There is no FDA in Europe.
The only control mechanism for European medical products are the doctors who use them. Therefore there is nobody who controls the implants Betz uses. He is free to test new prototypes with his patients without them knowing.
Nobody can be sure what kind of implant Betz will use on him/her.

Interesting. Can you share the link with the femur manual?

To be fair, Paley and Mahboubian also say that Stryde is full weight bearing, no?

I know that some patients had a hard time with Betz, but that wasn't my case. He was super cautious with me because I had the 11mm Betzone (the older model) and lengthened a lot (against his advise of stopping at . That's why he only gave me the ok to walk 9 months and half after the  surgery.

But then what's the difference between STRYDE and Precise 2.
As I taught full-weight bearing was the selling point.

Well, Stryde seems to be much MORE weight bearing than Precice, that's for sure.
But - considering NUVASIVE official guides - it seems Stryde is much closer to the current Betzbone than people would like to admit: a nail that can be full weight bearing only if you are very careful.

But that's just a guess. I'm really puzzled by the fact that NUVASIVE position is different from Paley's, specially because he worked with them to develop the nail.
