Oldest recorded instances of Cosmetic Limb Lengthening? Studies?

Edit Post

The Ilizarov apparatus has been around since the 50s, and CLL developed from there. I think the vast majority of members are aware of the immediate and (relative) short-term risks of LL here, but I don't see much talk about the long term. Are there any studies out there that followed the early CLL patients? Did their situation deteriorate in old age? I think this would be important information to know, even for those who have made their research and are aware of the surgery's and its initial years' risks.

This is not about the CLL patients, and I found it posted elsewhere in the forums, but I thought it'd be good to share this here:
