All I can find about Dr. Parihar online is about external fixator. But I will dig deeper?
Is the Greek doctor called Dr. Giotikas?
Yes the Greece guy is giotikas.
Yes parihar mostly performs external and has probably only performed max 7-8 internals AFAIK. But he's good, has decades of experience, isn't after your money ,is ultra cautious, has 0 complication rate(I can vouch for that since I'm an Indian and I have talked to docs to know about different leg deformity surgeons), is trained under Paley.
Externals is not necessarily bad. In tibias you should actually prefer externals over internals. (At least that's what a relative of mine told me. He's a doc although not exactly a field he specializes in).
The only reason why you might want to avoid Parihar is that it is in India. I'm from India and people from the west tend to have problems here. My sister had an Australian friend. The girl apparently had no issues whatsoever here. Idk, some people face a lot of difficulties here and others go Yolo ,eat street food yet face no issues. I really can't comment on that. Idk if there is a way based on which I can predict how much of a difficult time you'll have here but I would say - if you live in a hotel+ don't eat fuchka,paratha,spicy chicken/mutton/curry that you're not accustomed to+know someone here to guide you and help you - I don't see how you can face issues here.
But I'm a moron, talk to people before you go anywhere ,be it Greece or India or Africa or fricking Bermuda triangle. Talk to people.
Also, getting an apartment here in Bombay is a problem. You might only get a hotel. But if you know people here who can arrange a place for you or something. you're looking at spending 70$ a month in a pretty good place (obviously if you share it with 2 dudes). A caretaker would cost less than 50$ a month. I mean plan things well in advance with someone you know who lives in Bombay.
note- I dont live in Bombay. I live in Calcutta. So I'm of no help
