From what I've read, humerus lengthening is less dangerous than CLL however provides much less benefit so there's not much reason for it to be done. But everyone on here acts as if it's much riskier.

This forum needs to pay more attention to scientific studies in general. We are biased to hear bad outcomes.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2323419/
"The humerus is the best place for bone lengthening".

"We found that the humerus had almost the same healing index (range: 25–40 day/cm) as the bones of the lower extremity, but patients who had humeral lengthening had a faster functional recovery. Functional recovery following tibial or femoral lengthening takes about 32 months; this is in contrast with humeral lengthening, which takes only 8 months"

We know that most people recover well enough to function properly in around 8 months from femoral and tibial lengthenings, however they might be talking about more extreme situations and are also talking about frames. I assume they mean absolute full max recovery.


here they are lengthening like 8cm which is probably the absolute max you would ever have to do to compensate for cll. Paley goes up to 5cm. Obviously I think the first few weeks of this would be very bad and probably worse than cll just because of your limitations, but using a WB nail (which paley does) I dont see how this would be even remotely as difficult as CLL is in the long run. You also consider that when you lengthen both arms it's not like legs, 5cm of lengthening gives 10cm wingspan.

perhaps if you are very rich you could stagger the lengthening by a few weeks (obviously this would add an extra procedure cost to put the second nail in). Using wb nail this would be a far easier process in theory.


interested in what others think and to see if there are any contradictory studies.

no one ever said that!

Humerus lengthening is awesome, if you discount the fact that lengthening with Internal implants causes injury to the rotator cuff.

Forearm lengthening for cosmetic purposes is a sin however

people on here like to tell people never to do it, glad a doctor agrees.

is the rotator cuff injury significant or permanent? I consider myself a future humerus lengthening patient, likely with you so im curious what that means

Hello, one of my arm is shorter to the other one due to an accident when I was young, Do someone know how expensive it is to do this operation for the humerus ?

Cosmetically (non-necessary) arm extension is really nonsense.

I mean for me, my arms serve as a reminder / future remnant of short stature, so it would benefit me psychologically and cosmetically to get them extended, just to 1:1 ratio as is natural.

Will talk later when you loose sensation or range of motion, even if it’s just slightly, for nothing.

why do you believe you know more than dr assayag and the medical studies?

I don't even know If I will get humerus done, only if I intend to do more than 1 lengthening which I intend now but things change unpredictably.

I'm not stupid, I won't let sensation or ROM be effected.

It’s not you to decide if that will affect you or not.

Dude arm lengthening is silly. The benefit is absolutely minimal and not worth the risks of said complications that can happen.

For example, curing height related psychiatric problems by LL is worth it if the downside is you get altert sensation in your feet and have to relearn using your legs.

Arm lengthening gives almost no benefit and relearning to use your arms is NOT worth it unless you have a profession where you literally don’t need your arms at all, which given how many office jobs there are is scarce.

Any doctor that is not telling you this benefit/risk evaluation is a merchant in my opinion.

Arm lengthening for cosmetic purposes is dumb, no one is gonna call you out for your arm span, different people have different proportions.

not if your doing 8cm or less but after that it begins to look strange on some people. I want to get to 180cm from 165 so I dont think I can get away with it even with my arms being longer than average for my height. im also pushing the leg to body ratio limits at that point so id rather not have short arms aswell because subjectively it looks better to have longer arms at that point because people with longer limbs usually have them uniformly

Dr assayag,

Is forearm lengthening that risky even for small amounts(around 3-4 cm) given that the patient rehabs constantly and is determined?

theres no safe way current precice nails can enter the humerus. retrograde entry isn't possible due to the shape of the nail and antegrade involves splitting of the supraspinatus which can cause issues long term, especially to those with existing rotator cuff issues

Hey ! I have (or had) the same arm limb discrepancy as you. I live in France and one month ago, I have done my arm surgery (right humerus shorter 8 cm than the left). I have currently an external fixator on. Everything is going well for now. Plus, I have gained 2.5 cm since. Moreover, I will start my physiotherapy Monday because I have started to lost range of motion.

It’s awesome actually. I am not afraid about scars. They will slowly fade away over time and it’s nothing comparable to the joy to have the same arm and everything else ..

Feel free to contact me if I can help because I understand how you feel.

Arent you guy scared that your SHR will be less than .0, and your legs will look unproportionally long, compared to your torso? Im considering getting another surgery, its just that it will make my legs look extremely long
