Quote from: DonBones on April 29, 2021, 12:53:04 PMJust where does this opinion come from?
People seem to think that Betzbone breaks, but I have not heard first hand accounts nor am I ware of the circumstances of the break. If someone went skiing with that nail in, it wouldn't come as much of a surprise, for instance.
You should also keep in mind that Stryde breaks and Precise breaks as well. That is all documented in studies:
Styde: https://www.tandfonline.com/doi/full/10.1080/17453674.2021.1903278
"Unrelated to the scope of the study, but importantly, 2/30 femoral Stryde nails broke within 1 year after implantation (nail diameter: Ø11.5, Ø11.5; patient weight: 55 kg, 85 kg)."
It also causes lesions and pain.
Precise: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5253187/
"In the second case (loss of 10mm distraction) the nail broke shortly after the diagnosis and the nail was exchanged."
In addition to that Precise is not weight-bearing.
Betzbone does not have these problems. Now I don't mean to argue for one nail over the other, but it's important to keep in mind that there is no 100% safe way to do it and all nails come with advantages and disadvantages. In my opinion a statement like "Betzbone is overpriced trash" that is not supported by any evidence is irresponsible.
If you want to criticise something, then please do it, but also provide evidence and not rely solely on something you've heard somewhere.
Betz admitted himself that he had problems with nails and screws about a decade ago. On the old forum there were quite a lot of people with implant bending/breaking. However, two things come into play here. First, apparently the nail has been remodelled since then and in the past few years there was no report of nail breakage (as far as I know), second you have to keep in mind that people are responsible for this too. If you take the lengthening process light hearted and you start running or slip or whatever ofc that's gonna damage the nail. The fact that he lets you lengthen at home pushes this further (making you "forget" you do this from times to times probably).
However, I do believe if you are cautious and responsible the nail is a valid option, especially nowadays.
There are implant failures with magnetic nails too plus the rusting issue etc. So there are some cons as well. People will echo chamber that STRYDE is the best thing available, which is probably true but with it being gone I think the advanced albizzia nail (Betzbone) is a good option. First hand reports from Betz patients atm seem all be excellent.
