I don't know if it's 'a slight' risk man. Because it seems to me that things often go wrong more than not.
Apart from the 3 people I mentioned above (2 of which are veterans), there is you. But if I am not mistaken your surgery was more recent than Sweden and Medium of Drink Water.
Then there is Android. Did the surgery 2 years ago, suffered nerve damage, hasn't been back until now: http://www.limblengtheningforum.com/index.php?topic=8993.186
This is a guy who did a lot of research prior to the surgery, I'm sure he was extra careful all the time and still didn't go that smooth.
And a good doctor is not a guarantee. Guichet was once considered one of the best LL doctors.
I don't even read that many diaries, perhaps there are more cases like these.
I did LL on 2011, much before than all these.
With external tibias is it almost impossible to go too wrong if the doctor is experienced enough and you don't lengthen fast.
With internals, things are a little more riskier due to fat embolism as it is a much more invasive surgery, still if it is done right and don't lengthen much and fast, things will go well.
I truly don't believe that if you go to a good doctor (with whom you must speak a lot and see other patients of him after rehabilitation) the risks are significant, at least for permanent except some degree of athletic loss which is for sure.
Most LLers with good doctors are doing really good.
Even weirdos like Apotheosis with 3 surgeries (even in arms) at a not young age is doing very well and has a great body.
So LL has risks but for sure most patients are doing well. And the risks are truly worth it because it is the most lifechanging cosmetic surgery a short man can do. Benefits from LL are so big that even veterans like me, who had some problems due to doctors's faults (firtunately almost fixed), would have done another one if they had plenty of money.
That says a lit I believe .
