Is Dr. Doan in Vietnam legit? Any patients that have been there?

I’ve only seen like 3 diaries on him here, and it’s not even clear if they’re legit.

I have scrolled through his FB page and it seems he’s regularly having patients do 8-9 cm on Tibias. So either he’s a huge patient pleaser or else he’s simply spreading lies (but the latter seems kind of stupid because then he’s damaging his own business - better to lie about a bunch of 6 cm Tibia success stories, rather than lie about 8-9 cm Tibia success stories).

So what’s the deal with this doc? Is he legit? Anyone actually been there or anyone know of anyone that’s been there?

While you were there, did you see many Tibia patients doing 7 or 8 cm?

I’m worried about Dr. Doan’s ethics because on his FB page I see many 8 cm Tibia patients and that just seems crazy to me. It isn’t even just a few 8 cm Tibia patients, but many. That’s the real concerning part. Seems insane to me

If you remember correctly, even the Paley doesn't allow anything over 4,5 cm on tibias.

Get ready for a lifetime of wheelchair use, if you do 7-8 cm on tibias, since doing only the tibias, makes you more prone for arthisis and other joint problems - https://pubmed.ncbi.nlm.nih.gov/26398436/

There, you can lengthen your tibia by up to 10 cm, provided the surgery goes smoothly and you have the patience to endure relentless physical pain and mental exhaustion. However, once the external fixator is removed, the achieved length may decrease by up to 2 cm due to device inaccuracies.... You should also consider the tibia‑to‑femur ratio if you undergo a single lengthening procedure. Finally, you will need intensive rehabilitation afterward to ensure your Achilles tendon adapts properly to the tibia’s new length.

Device inaccuracies? This is the first time I think I’m hearing of that.

So if you lengthen Tibias by what you believe to be 6 cm using the LON method, once you finish, you may only get 4 cm at the end of the day???

The measured length often decreases after full recovery due to device inaccuracies, oversized screw holes, incomplete bone healing, and various other factors.

With a 6 cm lengthening, you may lose 1–1.5 cm upon recovery; with a 10 cm lengthening, you may lose up to 2 cm.

In that case it seems LON Tibia isn’t even worth it. That’s a huge joke if you could lose 20% of the length …..

first time I ever heard about that from LON, but would be crazy if you lose that much due to inaccuracies.

The loss of achieved length can occur for several reasons:

Under any method:

  • The body’s weight applies pressure on the screw sites - Especially at the bone ends, where the bone is softer.

  • When the nail is removed, the empty screw holes in the bone allow compression under load, causing a slight reduction in length.

Particularly with the LON method, length loss is more pronounced because:

  • The LON nail is locked in place after Consolidation phase, and the surgeon must find the screw holes for final fixation, often with limited precision.

  • Numerous pin sites from the external fixator enlarge as the bone is lengthened. After frame removal, these oversized holes—especially near the bone ends—leave voids that collapse under body weight, further shortening the limb.

Most patients don’t notice this change because they rarely re‑measure their limb length after the lengthening process is complete.

Therefore, instead of targeting an exact final length, aim for about 20% extra when using LON and 5–10% extra with other methods.
