Hi contacted Barinov’s clinic and here are the current prices:
Ilizarov surgery is 14 500 euros inlcuding 1 month stay in the hospital: surgery under spinal anesthesia, meals and medical care. Each additional month at the clinic is 1 200 euros with accommodation, meals and medical care. With 7.5 cm it may take about 8 months till the end of consolidation when the frames can be removed. So, totally it may cost 22 900 euros. There may be some extra expenses, too, if you need supplements to speed up bone regeneration.
At our clinic LATN alongside with Iizarov is also used. With this method you can stay 5 months at the clinic but you'll need one more surgery to implant the nails which costs 4 300 euros., so the price is hardly cheaper.
It's possible to reduce expenses if you rent an apartment and the clinic may help you to find it. This way you can save 300-400 euros a month.
As for complications, if you follow the surgeon's advice and exercise daily, the process is without any complications but I must say that lengthening requires hard work and a lot of patience.
