Sorry for the bit aggressive response... It's the Israeli in me.
No problems man, just advising you to get a second (and third) opinion on these statements. Yes, they are completely different from what Guichet and Paley say, but also from Baumgart, Birkholtz, Monegal, Rozbruch, and a large etcetera.
1) He lengthens between 5-9 (sometimes 10) cm on tibias (though he sais that in terms of proportions 9 is really pushing it and 8 is the max)
I asked about lengthening more than 5-6. He said that the blood vessels regenerate (And he is correct) and that one knows his limit when nerve pains start. The most limiting factor is the muscles and the achilles tendon (which cause bent knee and ballerina respectivly). I asked him about athletic recovery. He said that from his follow-ups, those that went skiing returned to skiing, those that went swimming returned to swimming and those that were running returned to run.
He advocates for atleast 5-6cm (he usually dont accept people who wanna do less) because he sais that it's not worth it (the process and psychological burden).
It is very, very strange that he uses 5-6 cm as a
lower limit. Virtually any other doctor agrees that going
over 5 cm is dangerous. As an example, I'm going to quote Franz Birkholtz:
"Tibial CLL should probably be limited to around 4-5cm. This has to do with muscle tension and contractures primarily. Although the muscles to grow in the process of distraction histogenesis, there is an element of stretching that has to take place as well and if this is excessive, contractures result (eg ballerina foot) and this may be permanent."Many patients (Sweden, for example) regret having done more than 5 cm in tibia.
3) No LON or LATN (Says can cause misallignemnt problems which are much more difficult to deal with unlike pure externals)
LON or LATN can cause misalignment problems? Intramedullary nails were developed to prevent misalignments often associated with purely external fixators. So this statement sounds quite weird... Did he explain this further?
4) Achilles tendon lengthening is not the big black boogieman that this forum (and the other one) s saying it is (It usually starts between 4-6cm and he prefers to do it immidiatly as it starts because prognosis is much better than to wait it through physiotherapy)
See crimsontide's previous post
6) time frame is usually the same in terms of healing (9-12 months)
Not sure about what he wanted to say with this.
To sum it up, I would get a second and third opinion. Ask Birkholtz, for example. He has a Q&A thread here, and he also offers externals & Precice (as well as LON/LATN). Email Guichet or Monegal. Let's see what they have to say about these things.
And as a final note:
What I really liked about him that a few people in the town (lecco) said that even though as a person he can be pretty bad, as a doctor he is number one (when we asked people where Catagni's studio is and then we asked them about him).
It may sound childish, but I don't want a bad person to be my LL doctor. Aftercare could be an issue.
