[BetzLandLiberator]

Hello,

I did LL with Dr. Betz some years ago (2012) and I'm thinking about doing the tibias now.
My results with Betz were spectacular so I'm considering him agian but of course I'm really interested in the new Stryde system.

It seems all the diaries here as well as the most well know doctors (e.g. Paley, etc...) say that Stryde is full weight beariing and you can walk without crutches during lengthening (something you cannot really do safely with Betzbone).

But I was reading the official literature of Stryde by NUVASIVE (the company who manufactures Stryde) and they categorically say that Stryde CANNOT withstand full weight bearing. Their description actually seems very similar to Betzbone. Check here on page 22:

https://bdhmedical.nl/wp-content/uploads/2019/06/Stryde-Tibia-Operative-Technique-1.pdf

Consolidation Phase
The Stryde implant cannot withstand the stresses
of full weight bearing. The patient should utilize external
support and/or restrict activities until consolidation occurs.
The consolidation phase should occur with the Stryde
implant in place.
Increase to unrestricted full weight-bearing only after
careful clinical and radiographic evaluation of the patient.
Full weight bearing is only permitted when there is solid
healing of at least three out of four cortices on the A/P
and lateral radiographs as determined by the physician.

I don't know what to make of this. Paley is one of the best LL doctors and he says Stryde is full weight bearing and you can walk during lengthening. And a lot of diaries here (with videos) show people doing just that.

But Stryde's manufacturer says otherwise.

What do you guys think?

[Medium Drink Of Water]

3 out of 4 cortices was how Dr. Peng decided you were ready to have the nail taken OUT.  Yikes!

Interesting. Maybe NUVASIVE is more conservative than every other doctor?
What do you think about this discrepancy between Stryde's official literature (non full weight bearing) and the way doctors are advertising (full weight bearing)?

Must be a typo with Presice 2 because I've been fully weight-bearing and walking unassisted most of the time since 1 month post-op , and then 100% unassisted walking since month 1.5 post op, and even had some instances where I had to jump/step hard into my legs and feared my nail could've broken but nope, solid nails.

It's not a typo. Check the link I provided. That's the official Stryde guide for tibia surgery. I know that there is a lot of cases like you and Paley and other doctors say the same, but I wonder why Nuvasive says otherwise.

I wonder if it is a situation similar to what we had with Betzbone around 2010-2011, a little bit before I had my surgery. Everyone was saying that the nail was weight bearing and we had diaries (in the old forum) of people walking without crutches. But when in the end of 2011/beginning of 2012 Betz changed the protocol and asked the patients to not walk without crutches unless they had more consolidation (similar to NUVASIVE guidelines).

[hanshi]

The definition of full weight bearing is that the leg needs to bear the full body weight. It can be done with or without crutches or other similar aids. Nuvasive is a responsible manufacturer who indicates limits of the weight bearing capacities of its product. With Betz it's different. He doesn't give any clear indications but simply states the nail is fully weight bearing. However in all cases were nails were bent or broken, of which there were many, he didn't follow the regulations( the manufacturer and the doctor both have the obligation to report these incidences to the authorities), refused to hand over the explants to the patients and put the blame on them.
The whole business model of a doctor who prescribes his own product to patients is against regulations and also against the code of ethics for doctors.

People in this forum should be cautious of people shilling for these kinds of "doctors".

[Movie]

Don't really care for checking the link bro, we all know stryde is weight bearing lol even our doctors say so, so possibly just something they're saying to not get sued incase someone has an issue and tries to sue for them "not being weight-bearing" like they said... the only thing I could think of

[BetzLandLiberator]

People in this forum should be cautious of people shilling for these kinds of "doctors".

I'm not shilling for Betz. I just cited him because I did my first LL with him and it was successful.
But I hated to be on crutches for almost a year and I'd like to avoid that if I do my tibias.
That's why I'm interested on Stryde and curious about the difference between NUVASIVE's official position and the doctor's.

P.S. I'm only using the name BetzLandLiberator because that's the name I used in the old forum (as BtzLandLiberator, without the E).

That's what crossed my mind to, but if that's the case the doctors would not say the same because they could be sued.
Anyway, i have an appointment with Dr. Mahboubian in December, so I'll ask him about NUVASIVE position.

[Tomhard]

Hey, how much did you lenghten with Betz?
Because you said you were on crutches for almost a year.

[BetzLandLiberator]

Hey, how much did you lenghten with Betz?

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.

[Medium Drink Of Water]

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?

[hanshi]

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.

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.

Thanks! I'll read her/his diary!

Hey betzlandl.
I sent you another PM

[Montreal172]

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.

The Stryde is far more superior than the betzbone ... there is no comparison...

[BetzLandLiberator]

I thought so too but now I'm not so sure for two reasons:

1) Stryde's manufacturer, NUVASIVE, says the nail is not really full weight bearing. Their description sounds EXACTLY like Dr. betz description of Betzbone. Meaning, it is weight bearing as long as you are careful.

2) The last diaries of Betz's patients shows that they were walking without crutches during lengthening with the last Betzbone.

But, who knows? The old Betzbone that I had (11cm) was definitely not full weight bearing during lengthening, but it seems the new patients have a totally different experience than what I had in 2012.

Explain in more detail. Thank you.

[TemakiSushi]

10mm Stryde has the weight limit of about 75 kilograms
This means it’s not full weight bearing for whoever weigh more than that
But these thin nails are used mainly for women and very short guys with thin bones
Such big company will never write things in the manner where they might have litigation issues.

Betsnails are such a crap using clicking system which is non reversible.
Also clicking is quite painful when lengthening
MaterHY was told that the nail had some contamination inside the nail
Any clicking nails are just craps

Better  to realize that there have been so many shills of Betz, Sarin, Guichet, Mitokovic, Mirzoyan, Sharm, Sha, Salameh etc.. for years of the forum history

What is Donghoon Lee's recommendation on nails and how much weight bearing?

About clicking being "quite painful" that's simply not true, at least not for Betzbone.
It wasn't painful for the majority of patients when I did in 2012.
In the new Betzbone moves even less, so it is even less painful now.

I agree that the reversible nature of Stryde is pretty good for non-union cases and the lack of clicking mechanism means the nail is probably more stable.

Better  to realize that there have been so many shills of Betz,

So anyone that had a good experience with Betz (10cm on the femurs and total recovery of athletic abilities) is a shill now?
So are you a shill for Stryde?
It's impossible to have a serious conversation with this attitude.
I'm considering both Stryde and Betzbone for my tibias.
I think Stryde seems to be the better nail but the NUVASIVE official position about not being weight bearing took away my certainty.
And so far no one could explain why NUVASIVE says something while Paley and the other doctors say something different.

This is one of the reason why I’m leaving this forum. 

If you are comfortable with the Betzbone and has great results from it and that doctor why would you try to convince yourself or other to think otherwise.

Personally I just had my femurs done with success and lengthened the Stryde to the max of 8cm plus walking around in the house without crutches, full weight bearing, with an outstanding doctor.

If Stryde is not fully weight bearing, how am I able to take my first few steps the day after surgery.  I been standing in the tub to shower, brushes my teeth and more. Plus if you watch the videos from Movies dairy, there my friend is solid proof that Stryde is fully weight bearing and there are no videos of other implant nail from a forum user.

I’m not here to promote or trash any doctor or implant nail, but if I’m going to do my tibias also I would not have any second thought of doing it with another doctor or different implant nail unless there is an upgrade on the Stryde nail by Nuvasive.

So no I will not be asking this forum for advise on a new or old implant nail or doctor since I had successfully done it with my doctor and that company nail.

Sorry but it sound like you are just trying to bring up talks about the new Betzbone and Betz like a promoter and not here for real advice since you have an answer to all your replies.

We all know which is the superior and safer implant nail so please just go with your new Betzbone and Betz since you had success on your first go around and stop trashing, Stryde nail by NuVasive.

To all that’s reading this tread and considering CLL, please do your own research on the doctor of choice and nail implant and not be influence by any tread or any “not so silent promoters.”

Oh I already know you will have an answer to my reply😂, so you can continue to keep this tread going.

[BetzLandLiberator]

Dude, are you crazy? I'm not trashing Stryde.
I said more than once that Stryde is my preference right now and it seems the best nail.
I brought an OFFICIAL GUIDELINE by NUVASIVE saying the nail is not full weight bearing.
Is NUVASIVE trashing their own nail?

I'm just trying to understand this.
If anything, you sound like a promoter of Stryde, not me of Betzbone.
