Quote from: Uppland on February 15, 2015, 12:28:45 PMYellowspike have you asked guichet about the angle of your femurs, we recently had a topic about this where some people thought it could cause problems with your gait and put etra pressure on your knees.
Dr. Monegal said it's avoidable with a good surgeon, what does Guichet think?
http://www.limblengtheningforum.com/index.php?topic=1760.0
Dr. Guichet said my knee pain on my right knee was caused by a contracture (which he identified in my first consultation and said I probably shouldn't do more than 7cm max because of this), and the pain on my left knee was simply due to the muscles being stretched (and the pain on each knee did feel slightly different). He said as long as the knee cap itself isn't in pain (and it never was for me), it's not much to worry about, and will subside after clicking stops.
Yellowspike - Dr. Guichet, Internal Femurs, Late 2014
5'8 isn't short in my eyes. It's only an inch from the average male height in the United States, and is extremely common (there just as many 5'8 men as 5'10.5 men in the United States). I know many, many 5'8 men myself and it does come off as a very normal height to the point that I usually notice many other things about a 5'8 person before noticing their height.

Agreed completely. That's why 5'8" was always my goal. To me, 5'8" is the start of where one appears "average," even though it's technically not (especially if you're lean and somewhat built like me). I still have some duck-ass, but I'm very happy even now at 5'8". I'll do some light clicking for a few moe days for good measure, but I'm happy now.

I was 5'8. it is actually a pretty good height especially if you wear lifts. I wanted to do LL bec I wanted to feel tall. You will definitely feel pretty average at 5'8. If at any point, you feel short, do this experiment.
Walk into a mall and eye-ball about 100 people. I think you will find that only 60-75 people are taller than you.
At 180 cm (5'11) in Singapore, only 10-15 guys out of 100 are taller than me. I wanted to do 182 cm because statistically only 10 (or less) out of 100 would be taller than me.
So, I think if your goal is average height, you've got it. People like us are insane cos' we do LL to feel tall 
Definitely, I wish u the best in your future endeavours. I started one week earlier than you but done only 4.5 cm on my tibias! I am doing very well but the femur lengthening rate you did was probably insane, was it?

Lol well 5'8" is still somewhat short...but to me, it's not so noticeably short to the point that you stand out like a 5'5" guy would (trust me, I would know). I don't care about being tall, I just didn't want to always be the shortest guy around. I can see why some of you do LL to actually be tall though.
Thank you, I wish you the best too 
My rate of lengthening slowed down every few weeks, but it was still fast enough that it was very painful for my body. Now that I'm home I've sorta slacked off on all the exercises, but I've been making sure to walk as much as I can. I think I'll stop clicks in a day or two because I want to start recovering. My gain is probably more like 6.8cm or something.

5'8 really isn't short. Even 5'7 is barely short, while 5'8 is pretty much the 35th percentile of height.
yellowspike, could you ask guichet about loss of height after lengthening " x " centimetres? apparently some patients on other threads (disobedient, and Sweden) lost a few cms after femur lengthening? is it due to the angulation of the femur bone? willll this happen with tibia (ive never heard of this for tibia)
cos if it is compressive loss its usually about 3- 4mm.

I can already answer this because Dr G already told me. He said in some (not all) patients, after lengthening, you lose 20mm in height that you gained due to compression. That's the number he told me. That's partially why I clicked to 6.65cm on his file (though I still think I gained a bit more). I don't really care because 20mm is very negligible my goal was 2.5 inches (6.35cm).
When lengthening tibia, you can lose 2-5 mms. The amount of loss depends highly on the fixation stability, with externals pins often bend with time and compression happens (to some extent). In modified Ilizarov full-ring fixators with half-pins the risk is minimal due to 2 to 3 times higher fixation stabiltiy compared to classic Ilizarov full wires-only or to half-ring fixators. With internals stability should also be better, but I guess they also can bend under pressure to some extent (the nail itself or the screws).
The same can be said about femurs, expect that they're also usually angled at 10 degrees in men and 15 degrees in women. Let's say you lose 50% of the length gained in the femurs if it's angled at 45 degrees, at 10 degrees that would be if rounded 5 times less, so 10%. Out of 7 cms lengthened you should expect to lose 0.7 cm or 7mm. This is confirmed by the following study:
http://www.ncbi.nlm.nih.gov/pubmed/22933497
QuoteIn a normally aligned limb, intramedullary lengthening along the anatomical axis of the femur results in a lateral shift of the mechanical axis by approximately 1 mm for each 1 cm of lengthening.

I'm a bit confused by this. So, if one has perfectly aligned limbs, they lose about 10% of what they lengthen due to the new angle of the femurs?
I was slightly bow legged before LL, and I'm not now. I remember looking in the mirror and "fixing" my bow legs, and it seemed to increase my height. So I'm wondering if this applies a bit less to me since I was previously bow legged.
Dr. Guichet himself said several times that we stand to lose around 20mm due to compression, and that it doesn't occur in all patients. So I'm inclined to believe him. I'll ask him about this link.
I also wonder if this applies less to weight bearing internal devices (like the Gnail) since they're stronger. You'd think they could withstand more and not compress as much.
