The new Fitbone nail seems to support full weight bearing below 200lbs. Seems to be much better than the mechanical nails (G-nail, Betzbone). Seems like a PMax replacement worth considering. Am I missing something?
Why is it not discussed more around here?
-
Where did you hear it supported full weight bearing below 200lbs?
-
A few people were discussing it on the d server. Also in a recent consult with Victor (Cyborg4Life) he mentioned something similar. Like the PMax it only has a weight-approval of much less but the max fatigue load seems to be not much different from the PMax. Birkholtz started using it on a few CLL patients. Still off-label for increased weight bearing. This is just what I have heard, thus my thread
-
I heard from an orthofix rep that it has been pulled from market for more testing, date of return is unknown at this stage.
-
Fitbone was always very unreliabe. Many times it stopped working.
I wouldn't trust it as an alternative to precise max.

I just looked at the literature. In this study (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9940487/) there were not many additional complications compared to the precice system. Also this study by Peter Thaller https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7744673/ also does not seem to have many device-related complications.
Given the renewed delay of the PMax, the question becomes whether the weight-bearing abilities outweigh the small increase in device-related complications.

What's the cost for 2 nails only?
-
this discussions is point less until the nail is approved in your country (FDA, CE, MHRA etc. etc)
I would not use any nail until approved by them and a reputable surgeon offers it
-
Yeah dr paley and his team really sucks
-
No the discussion is not pointless as surgery can be done with Birkholtz or Germany, where the nail is already in use
Also, it has been FDA approved recently: https://www.medicaldevice-network.com/news/orthofix-fda-fitbone-system/
Here is the clearance letter: https://www.accessdata.fda.gov/cdrh_docs/pdf23/K233867.pdf
According to the letter, it is available in 9, 11, and 13mm
Only the trochanteric (anterograde) entry nail for the femur has been cleared as far as I know
-
Do you know the price of the nails?

I could not find any source for CE mark approval of the new Fitbone nail. Do you have a source? because you said it is used in Germany.
In the US, no well known surgeon uses it for cosmetic. Do a search on the Fitbone surgeon directory.
South Africa is quite risky. I would not trust their medical board even if Dr Birkholtz is good. Getting a brand new nail inserted into both femur bones? better be sure that it has full regulatory approval of developed countries if you asking me

I sent Thaller an email but I guess you are corrent in that there is no EU approval yet only US - similar to the PMax nail.
Yes, you are correct in that using that nail in SA is probably quite risky. However, it does have regulatory approval by the FDA if that means anything. Also, I know of one Birkholtz patient who is 1.5cm into distraction with the new Fitbone and no issues thus far. Given the nail is made of Molybdenum it is unlikely to break - worst case scenario is probably that it stops distracting.
However, the P2.2 has issues with locking bolts.
The question still remains whether the increased weight-bearing during distraction outweighs the potential risks of it being a new decive.

So far Birkholtz hasn't even used the new fitbone yet. Orthofix is saying it only had limited release in the US and has now put it on hold, it was still in the process of getting approval in South Africa before the hold so impossible for any patient there to have used it. No doubt the new fitbone is still a decent nail but all the delays mean surgeons will just go with the more popular Precise max when it's released again. Unfortunately Orthofix just took way too long to release the new fitbone when they could have had the market to themselves.
-
Looks like the new precise is delayed until 2026, so Fitbone has an opportunity to capture the market this year.
Anyone know why the delayed? Was it because of the precise max issues?
-
Forget p max bro. Is out of the market
-
I do agreed. Pmax is just out even if goes out tomorrow I will chopse betz or other nail.. that ridiculous paley and that nail. They just can make a good FW nail, they just can’t .. after 5 years paley fail, 2 recalls is just a fail..
-
I just got off a call with Dr. Birkholtz about my own surgery. He offers both the fitbone and p2.2, but he urged me to go with p2.2 since his installation and lengthening using p2.2 is a basic Tuesday, whereas fitbone is still experimental territory for him.
IMO this process is going to be filled with anxiety as is, and I don't want to be freaking out everyday over potential bent nail / alignment problems because I'm pushing the boundaries of a device that may or may not be properly weightbearing.
EDIT: grammar
-
What's the cost of the surgery using fitbone nail with Dr. Birkholtz?
-
same cost, I believe. He didn't mention any price difference.
-
62,500 for femurs, but is going to be pricier if you're going for more than 6.5 cm since he expects 4+ months for 8cm rather than 3 (and it's an all-in package, including food, meds, and housing).
To be clear: I did not ask for fitbone costs but he made no mention of different pricing.

Is the fitbone he offered weight bearing?
-
With the additional delays of the new Precice, you could have had your lengthening done and beam just about recovered when using the old system as opposed to continuing to wait for a possible release that may get pushed back yet again.

It's semi-weightbearing in theory, but not officially approved as a weightbearing device. I forgot the actual weight limit, but it's something >=200lbs.

For the TAA11/13 model, the maximum patient body weight is 100 kg (220 lbs)
For the TAA09 model, the maximum patient body weight is 50 kg (110 lbs)
